	<![CDATA[
	<p>The Sheldon Memorial Art Gallery and Sculpture Garden is pleased to present <em>Food for Thought</em>, the thirteenth annual Sheldon Statewide exhibition. Sheldon Statewide is a unique collaboration between the Sheldon Gallery, the Nebraska Art Association (a nonprofit volunteer membership organization dedicated to the advancement of the visual arts in Nebraska) and the efforts and cooperation of the many Nebraska communities that serve as exhibition venues. The mission of the Sheldon Gallery is the acquisition, exhibition, and interpretation of 19th-20th-century American art. Sheldon Gallery has achieved a national reputation for this collection. Each year twenty works from this collection are circulated throughout the state of Nebraska.</p>
<p>The 1999-2000 Sheldon Statewide exhibition focuses on a popular yet powerful subject for artist in the Western artistic tradition. <em>Food for Thought</em> assembles a diverse group of artists, working from diverse perspectives and with diverse intentions, who have chosen to represent food.</p>
<p>Food is the very stuff of life, it nourishes us, sustains us, even gives us pleasure. However, in the hands of artists, food is transformed aesthetically and imbued with added meaning and significance. The representation of food in the Western artistic tradition has served a variety of symbolic purposes. First and foremost is the representation of the material beauty of the world around us, a beauty that has intrigued and seduced artists for centuries. Second, some artists have represented this material beauty in order to emphasize its transient nature, thus serving to redirect attention from the temporal pleasures of this world for the presumably more enduring concern of one's soul.</p>

<title>FLOWERS, LIES AND REVOLUTION:
CONTEMPORARY CUBAN ART</title>
<link>http://digitalcommons.unl.edu/sheldonpubs/32</link>

	<![CDATA[
	<p>Flowers, Lies and Revolution surveys some themes that emerge in contemporary Cuban art, as revealed in three private collections in Lincoln, Nebraska. What a landlocked state and a sea locked nation share are the desires, comforts, and complexities of the other. This exhibition celebrates the transnational scope and vision witnessed in the breadth and focus of the three local collections: those of Karen and Robert Duncan, Kathy and Marc LeBaron, and Lisa and Tom Smith.</p>
<p>The collections represent the dominant trends of a new generation of Cuban artists that emerged in the last 30 years. Their work continues a tradition of testing the limits of artistic freedom in Cuban society-a critical practice consistent with the Cuban Revolution in 1959, but which fell under intense state scrutiny in the 1970s.</p>
<p>In recent decades artists have worked with increasing self-reflection in responding to life in Cuba. They have explored new representational strategies with which to frame their aesthetically and conceptual responses. The art they produce is less concerned with the standpoint of the collective-an earlier, revolutionary interest-than with the individual's response to the collective-a later, laissez faire interest. The island's contemporary art reveals an increasing sensitivity to individualism in its critical responses to Cuban society.</p>

	<p>Symbolizing purity, sustenance, tranquility, power, movement, and continuity, water is a source of life as well as destruction and death. Its surface serves as a metaphor for self-reflection and contemplation. It flows over cultural and physical boundaries. Water is indispensable to human survival, yet many take it for granted. We pollute it, misuse it, and fight over it. It is easily accessible to some while nearly out of reach to others. <strong><em>Flow</em> </strong>explores the theme of water as subject and symbol, natural wonder, recreational resource, and environmental concern.</p>
<p>Artists with an affinity toward nature, especially landscape painters, chose water as a primary subject because of its reflective beauty and emotive qualities. Those close to the land also wish to protect it, and to do so some have turned to documentary imagery. Water was a central theme of the Provincetown, Massachusetts, painters and the San Francisco Bay Area figurative artists. American Impressionists gravitated toward water's abstract, absorbing quality.</p>
<p>Water and exceptional light drew artist and art teacher Charles Hawthorne to Cape Cod, where he helped established an artist colony and persuaded Ross Moffett to join their circle. Although Moffett studied in Chicago and New York, he was born on an Iowa farm, and could identifY with the Portuguese fishermen in the west end of Provincetown. "I regarded this group as proletarian," he wrote, "at least as a working class, and .. .! thought, not too difficult to connect them with farmers .... " <em>Red Dory</em> exemplifies Moffett's attempt to depict the fishermen and their environment as inseparable, organic elements. His use of patterning, negative space, color, and form reflects his interest in modernist ideas as well as life on the water.</p>

	<![CDATA[
	<p>As the art musem of the University of Nebraska, the Sheldon Memorial Art Gallery staff is committed to making the exceptional permanent collection available to all Nebraskans. The Sheldon Gallery's Statewide Touring Exhibition Program realizes that goal by circulating art of the highest quality to communities throughout the state. Each Statewide exhibition addresses an art historical genre or theme , and together the five exhibitions constitute a mini-art history course and a unique focus on the Sheldon Gallery's renowned collection. As the exhibition series continues , the relationships between diverse artworks are increasingly apparent.</p>
<p>FISH, FOWL AND FAUNA, offers a selection of animal images drawn from the permanent collection that document a variety of stylistic, art historical and technical resolutions to the familiar subjects. Like the previous statewide exhibitions, FISH, FOWL AND FAUNA spans approximately one-hundred fifty years and includes examples of painting, sculpture, and works on paper, made by both academically trained and folk artists. From internationally renowned sculptor Alexander Calder's abstract bronze, Snake on Arch, to the charming iron frog decoy made by an unknown artist, and from John Woodhouse Audubon's 19th century zoological study of the Californian Hare to the expressionist painting, Longhorn #7, by Theodore J. Waddell, a wide variety of artistic responses to the animal kingdom is evident.</p>
<p>While many staff members contribute to the year long preparation of each exhibition, we are especially appreciative of the efforts of the Community Programs Coordinator, Lonnie Pierson Dunbier. Ms. Dunbier has 'luthored the notes which support the photographs herein , and she has trained innumerable volunteer docents to conduct local tours in each hosting community. We also thank Curatorial Assistant, Karen Williams, for her thoughtful design of this brochure.</p>

	<p>Among the various types of artistic expression, portraits are probably considered the most approachable by the greatest number of people. And yet, upon closer consideration, it is evident that no amount of scrutiny on the part of the artist, or the viewer, can deliver the portrait from a fundamental limbo resulting from its dual referential and aesthetic functions. The portrait partakes of a variety of truths, but never resides within anyone verity. The philosophical debate about the nature of likeness has raged since the time of Plato, and remains unresolved.</p>
<p>The motivations and limitations of portraiture have changed over the course of history. During the Renaissance, portraits were used not only to record historical personages, but also to advertise the role of the subject. The sitter typically sought to be portrayed as if "from nature," a request which required the artist to achieve a "true likeness." But Renaissance verisimilitude was acceptable only in an idealized form, thus Renaissance portraits typically achieve a balance between the classical ideal and actuality. Artists sought this balance in different ways, some accentuating the real, some the ideal. Thus, while facial imperfections and idiosyncrasies are faithfully recorded, an idealistic veneer is also apparent.</p>
<p>During the seventeenth century, portraiture more directly embraced the mind of the subject. Artists were fascinated with the details of costume and peculiarities of character. Also, dramatic lighting was used to promote the importance of the sitter to the viewer. Typically, the subject would directly encounter the viewer with a steady gaze. Sometimes an arm or hand would drape over a foreground windowsill or ledge. Thus the subject's proximity to the picture plane made the subject appear to enter the viewer's space. The Baroque portrait style was perhaps the most influential type, and remains the dominant traditional approach to likeness.</p>

<title>Using Targeting Outcomes of Programs as a Framework to Target Photographic Events in Nonformal Educational Programs</title>

	<![CDATA[
	<p>Targeting Outcomes of Programs (TOP) is a seven-step hierarchical programming model in which the program development and performance sides are mirror images of each other. It served as a framework to identify a simple method for targeting photographic events in nonformal education programs, indicating why, when, and how photographs would be useful to inform other evaluation strategies. In two case studies, photographs enhanced the formative story of a geoscience project being developed and tested, and contributed to the outcome narrative of a 10-year partnership project between two universities. In both cases, TOP proved to be an efficient and easy-to-use framework. Using TOP in this fashion has the potential to help evaluators address challenges posed by the subjectivity of photography and possible biases of the photographer in the research process.</p>

<title>Evolving Eden</title>

	<![CDATA[
	<p>Eden is an idealized place where one experiences happiness, harmony and a sense of timelessness. While some believe this can only be experienced after death, others are convinced that the only Eden is the one we currently inhabit and therefore good stewardship is needed in order to sustain it. Photographers have historically captured our evolving planet and have brought to light its beauty as well as its destruction due to human intervention.</p>
<p>The artists in Evolving Eden address the much-discussed topic of the environment and our relationship with our surroundings, using three distinct approaches. While Arno Rafael Minkkinen's spiritual images attempt to eliminate the boundary between self and the external world, Hans Eijkelboom shows us a world of homogenous consumerism in an urban environment far removed from nature. Minkkinen's self-portraits leave those material objects and associations, including clothes, behind. He is the lone person in much of his work. Eijkelboom's subjects strive to obtain individuality through their personal style and dress, but in actuality they become elements in a larger collective. Edward Burtynysky's beautiful yet detached photographs of industrial wreckage capture the environmental consequences of consumer culture and exemplify a lack of responsible management of our natural resources.</p>
<p>Finnish-born American photographer Arno Minkkinen contorts his tall, thin body within pristine, Eden-like environments. Equipped with his lens and without the aid of an assistant, he photographs himself as being in a harmonious, solitary relationship with nature. Minkkinen's approach might best be described as spiritual or transcendental; his body can be seen as a metaphor for the land. For almost 40 years Minkkinen has created black-and-white, large-scale self-portraits, unmanipulated, and developed in his darkroom. They are evocatively beautiful yet serendipitous and witty in their defiance of what seems humanly possible to achieve. They take us to places seemingly unmarred by human intervention and remind us of the ideal to seek a balance with nature.</p>

<title>El Espiritu de Aztlan</title>

	<![CDATA[
	<p>The Spirit of Aztlan celebrates Mexican and MexicanAmerican art and its significant contribution to the development of American culture. Referring to the homeland of the ancient Aztec civilization, the term "Aztlan" evolved during el Movimiento (Chicano Civil Rights Movement) in a conscious effort to reclaim Native American ties and improve economic, political and cultural situations. This spirit of self-identity began in Mexico, with the Mexican muralist movement and artists such as Diego Rivera, David Siqueiros and Jose Clemente Orozco. Large mural and printmaking projects strengthened national identity and instigated change in Mexico in the1920s and 1930s. The United States government was directly inspired by the Mexican public art concept and consequently initiated the Works Progress Administration (WPA) to support art projects during the Great Depression. The Chicano art movement, which began in the 1960s, continues the Mexican muralist practices. Utilizing art as a tool for change and unity, artists Ester Hernandez and Rupert Garcia mass-produce posters and paint murals in a campaign to recognize Indian ancestry, address the lives of working class people, and promote spiritual and revolutionary themes. California artists Manuel Neri and Salomon Huerta create figures that lack identity and Mexican cultural associations and therefore further the conversation regarding the term "Aztlan."</p>
<p>Although the style of the Mexican muralists' work echoed that of their European counterparts, the subjects were inherently Mexican and realism was maintained in order to communicate with the masses. Equipped with strong personalities, artistic genius and support from good relations between the U. S. and Mexico, the "three greats:' Rivera, Siqueiros and Orozco, received much attention in America and made lasting impressions. In 1931, Rivera (1886-1957) was commissioned to paint a mural at the San Francisco Stock Exchange, and a retrospective of his work followed at the Museum of Modern Art, drawing a record crowd of 57,000 people. Rivera's self-portrait was created in 1930, the year he began experimenting with lithography. Capturing his full, rounded face and forthright stare, the work communicates confidence at this point in his career. I In Open Air School, Rivera depicts students of all ages, including adult field workers, who gather to broaden their education.</p>

<title>EARTH AND FIRE: CERAMICS FROM THE
SHELDON MEMORIAL ART GALLERY</title>
<link>http://digitalcommons.unl.edu/sheldonpubs/26</link>

	<![CDATA[
	<p>EARTH AND FIRE: CERAMICS FROM THE SHELDON MEMORIAL ART GALLERY, the sixth annual Sheldon Statewide exhibition is a diverse selection of ceramics made in America during the past 100 years. From delicate Victorian vases to commercial ware of the early twentieth century and contemporary sculptural works, this comprehensive assembly truly offers something for everyone.</p>
<p>Though EARTH AND FIRE addresses the American connibution to the ceramics tradition, clay vessels and figures have been formed by nearly every culture since the beginning of civilization. These objects, made of the very earth itself, were not only utilitarian, but also often ritualistic or created for purely aesthetic reasons. The earliest American ceramic objects - pots and jars from the ancient Southwest - date from about 850 AD through the late Pueblo eras. With the coming of the Europeans, more and more types of ceramic vessels were introduced to this country.</p>
<p>Included in EARTH AND FIRE are works by eccennic artist George Ohr whose work of the early twentieth century was unknown to the art world until the recent past. The art potteries of the late nineteenth and early twentieth centuries are represented by examples from the Rookwood and Grueby studios. The art pottery movement laid the groundwork for the establishment of an American ceramic tradition. The ensuing decades, up to mid-century, saw the emergence of characteristics that can be identified as peculiar to ceramics produced by Americans. During the last forty years these qualities have been more fully defined, most particularly in the works of those artists who were involved in and who have benefitted from the "revolution" in ceramics that took place after the second world war. Notable among these are sculptural ceramic works by masters such as Peter Voulkos, Tom Rippon, Peter Shire and Richard Shaw. EARTH AND FIRE also includes works by Nebraska ceramicists Gail Kendall and Margaret Furlong. Today American ceramics, once a stepchild of other cultures, is strong enough to influence many of those cultures on which it once depended.</p>
<p>As the art museum of the University of Nebraska-Lincoln, the Sheldon Memorial Art Gallery staff is committed to making the exceptional permanent collection available to all Nebraskans. The Sheldon Statewide exhibition program realizes that goal by circulating art of the highest quality to communities throughout the state. Each Sheldon Statewide exhibition addresses an art historical geme or theme, and together the six exhibitions constitute a mini-art history course and a unique focus on the Sheldon Gallery's renowned collection. As the exhibition series continues, the relationships between diverse artworks are increasingly apparent.</p>

<title>Divine Abstractions: Spiritual Expressions in Art</title>
<link>http://digitalcommons.unl.edu/sheldonpubs/25</link>
<guid isPermaLink="true">http://digitalcommons.unl.edu/sheldonpubs/25</guid>

	<![CDATA[
	<p>In Northern Europe during the early 1800s, artists began departing from the rationalism of the Enlightenment and the realism of traditional artwork. Their desire to express the mysterious and unseen essence of the divine through their artwork transformed the way we think about art. Called Romanticists, these artists valued subjective experience over reason and the individual experience rather than the collective. They abandoned conventional religious iconography and produced private, intensely meditative images, depicting the divine as something eternal and infinite. These artists believed that material reality hindered experiencing the divine. They sought to fracture the shell of physical reality to access an inner truth.</p>
<p>Historical factors contributing to this transformation included the diminished influence of the Catholic Church, improved education, and foreign travels. Intellectually, they were guided by historically far-ranging philosophies. Pythagoras, for example, taught them that there was only one substance, "the absolute," from which all things, from the minutest particle to the farthest star, were composed and that a world soul animated this unified reality. Spinoza also proclaimed that everything is a manifestation of the one substance, his concept of God. Jacob B6hme, a German mystic, had a vision of this unitary reality when he saw divine energy shining forth from every object around him. Madame (Helena Petrovna) Blavatsky in the 19th century introduced Theosophy; its doctrine asserts that all cultures and religions strive for spiritual awareness and would unite in the universal absolute when they evolved to a higher consciousness.</p>
<p>While the Romanticists were active in Germany, New England Transcendentalists inspired the Hudson River School artists. Influenced by Swedish philosopher, scientist, and Christian mystic Emanuel Swedenborg,Transcendentalists also saw a spiritual world underlying nature. American artist Ralph Albert Blakelock, for instance, maintained a Romantic artistic style, mystically reordering reality. Dusky evening scenes with luminescent moonlight became his signature style. Heavy Woods -Moonlight communicates a spiritual essence that envelops the viewer in a meditative stillness. Norman Geske, Blakelock biographer, notes that the artist "proceeded with an imagination that was singularly free of any allegiance to established procedures" and was "critically and tragically" ahead of his time in his abstract impressionistic style.</p>

<title>Dislocated Emblems: Recent Work by Warren Rosser</title>
<link>http://digitalcommons.unl.edu/sheldonpubs/24</link>
<guid isPermaLink="true">http://digitalcommons.unl.edu/sheldonpubs/24</guid>
<pubDate>Tue, 15 May 2012 12:30:12 PDT</pubDate>
<description>
	<![CDATA[
	<p>Though emerging artists often dazzle us with brash or daring work, the artist at mid-career has reached a level of consistency and retrospection that delivers the work from facile solutions. With a career that now spans more than twenty-five years, Warren Rosser's work has evolved into the kind of subtle dialogue between carefully honed technique and highly articulated personal vocabulary that is achieved only with the diligence and insight of maturity. "Dislocated Emblems" is a watershed of Rosser's long commitment to his art. These new works are the culmination of an intensely productive year when Rosser's aesthetic, philosophical, and emotional concerns converged, resulting in multimedia constructions that are both visually and intellectually compelling.</p>
<p>Schooled as a painter in his native South Wales, much of Rosser's work refers to the dilemma of rendering a three-dimensional world on a two-dimensional surface. This classic conundrum has led Rosser into sculpture, back to drawing, and, most recently, away from gesture and toward works that include photography and kinetic elements. Fundamental to his physical solutions is Rosser's reference to the human form. In earlier works, the body was an explicit subject. With "Dislocated Emblems," Rosser uses the verticality of the figure as an implied coordinate, a way of orienting the viewer to the artist's psyche.</p>
<p>Some of Rosser's titles give us an indication of his thematic concerns. Titles like Reflex and MemoryRevisited, Stages, and Union of Fortune- Tellers and Alchemy allude to the artist's interest in universal concepts such as the duration of time, the mutability of perception, and the transitory nature of human experience. Poetics aside, Rosser has committed himself to deciphering the plethora of information that bombards us daily, organizing and dissecting his visual language and placing it in a wider, philosophical context. He has set as his task the creation of "emblems" that signify the very stuff of reality: time, motion, and memory. Throughout the exhibition, single works are constructed as sequential imagery, to be read in real time, from left to right, or from top to bottom. Machinelike, motorized components churn and whir, lending magically absurd qualities to the more formal elements. In each work we are met with a complement of sensory signposts, as the eye moves from form to shadow, from actual space to the ghostly residue of a form, from static imagery to rotating contraptions which emit lowlevel repetitive sounds that mimic the body's pulse.</p>

	<![CDATA[
	<p>The Rohman name has been synonymous with the artistic an cultural life of Lincoln and greater Nebraska for decades. It can be seen on buildings and projects throughout the city and state, from Opera Omaha and the University of Nebraska- Lincoln opera program to the Museum of Nebraska Art in Kearney and Lincoln's own Meadowlark Music Festival. In summer 2005, the Rohman's were the first family to be honored with a named gallery at the Sheldon Museum of Art. But the Rohman's have also enriched the region's cultural heritage in less visible ways too numerous to count. <em>An American Taste: The Rohman Collection</em> pays tribute to their generosity to, and legacy at, the Sheldon, which has taken the form of a special, unparalleled, contribution: their art collection.</p>
<p>The Rohmans have continued to build this institution's holdings of nineteenth- and twentieth-century sculpture by donating pieces by Malvina Hoffman and Edward Thaxter, but perhaps their most visible contribution was to the acquisition of Claes Oldenburg and Coosje van Bruggen's monumental outdoor sculpture Torn Notebook (fig. 7), a work that has become synonymous with the University of Nebraska since its unveiling and, appropriately, greets all visitors to the campus and the city.</p>
<p>The artworks on display here and in Poetical Fire are but a small fraction of the more than one hundred objects that the Rohmans have contributed over the last forty years. The collection that bears their name is a testament to their astute eye and discriminating tastes, as well as to their generous philanthropy.</p>

<title>Decisive Line
Drawings by Dan Howard</title>
<link>http://digitalcommons.unl.edu/sheldonpubs/22</link>
<guid isPermaLink="true">http://digitalcommons.unl.edu/sheldonpubs/22</guid>

	<![CDATA[
	<p>In mathematics, a line is the geometric figure formed by a point moving along a fixed direction, and its major property is that it is one-dimensional. In art, however, line has much more than a single dimension. Lines are mutable and chameleon-like in character-they can be soft and seductively flowing, agitated and emotionally loud, or passively descriptive. Line also serves as the fundamental element of most drawings. In this exhibition, Dan Howard reveals his continuing fascination with, and mastery of, line. Composed not only of charcoal, graphite, and pen-and-ink drawings, but also of oil paintings, this array of works showcases the artist's fluency in drawing and represents just a sampling of his production over the past two decades.</p>
<p>Although drawing is often dismissed as preparatory in nature, it is in fact central to most visual enterprises. The revered neoclassical artist JeanAuguste- Dominique Ingres declared, "Drawing is the probity of art. To draw does not simply mean to reproduce contours; drawing does not simply consist of line: drawing is also expression, the inner form, the surface, modeling." To Ingres and to many others before and since, drawing constituted the bedrock of art. One only need look across the expansive history of art to see the truth of his assertion. Renowned artists such as Leonardo da Vinci, Albrecht Durer, Kathe Kollwitz, and Pablo Picasso produced breathtakingly affecting and impressive paintings, prints, sculptures, and works in other mediums, all of which stemmed from their enviable abilities as draftsmen. And drawing's importance is not limited to the West; consider the centrality of ink drawings to centuries of Asian art.</p>
<p>In <em>Decisive Line</em>, the primacy of drawing-and line in particular-is on full display. Most of the works on display here, especially those done in graphite or pen and ink, consist predominately of crosshatched lines. This is consistent with Howard's working methods over the course of his career, which got an early start. The artist was born in Iowa City in 1931 and majored in art as an undergraduate at the University of Iowa. After a short stint in the Air Force in the mid-1950s, he returned to the university, where he received his Master of Fine Arts (with a concentration in painting) in 1958. After moving through the ranks at Arkansas State and Kansas State universities, Howard came to the University of Nebraska-Lincoln in 1974 as a full professor and chair of the Department of Art, in which capacity he served until 1983. He retired in 1997 but has continued the vigorous practice that he established years earlier.</p>

<title>Some Notes on Nebraska Birds: A List of the Species and Subspecies Found in the State, with Notes on Their Distribution, Food-Habits, etc.</title>
<link>http://digitalcommons.unl.edu/biosciornithology/83</link>
<guid isPermaLink="true">http://digitalcommons.unl.edu/biosciornithology/83</guid>

<description>
	<![CDATA[
	<p>For upwards of twenty-five years the writer has taken an interest in our birds and made notes relative to their abundance, migrations, nesting, food-habits, etc., simply for personal gratification.</p>
<p>About two years ago, during a conversation in which the relation of birds to horticulture incidentally arose, Professor F. W. Taylor suggested the advisability of devoting a portion of a succeeding annual report to our Nebraska birds. With this object in view both the professor and the writer broached the matter to other members of the Society. Several at once not only became interested in the matter, but suggested its early accomplishment. Our late lamented Secretary, D. U. Reed, was especially in favor of the scheme. Accordingly it was decided that my usual report as entomologist should be omitted from the present volume and its place given to one on birds.</p>
<p>It is on these grounds that I now present for publication some " Notes on Nebraska Birds," and it is to be hoped that they will in a measure, at least, have the desired effect, viz., the protection of our birds, which means the destruction of insect pests in proprotion as the protection reaches out. Just so soon as it was decided that this subject be treated in the present report efforts were at once made to secure all such additional material and information as would tend towards making our knowledge as complete as possible. Correspondence with various persons interested resulted in the bringing together of notes taken by about forty separate workers located in different parts of the state.</p>
<p>By referring to the catalogue on the succeeding pages it will be seen that there are 415 distinct species and subspecies listed. Of these, future more critical examination may eliminate six or seven forms. Perhaps it will also be found that at least twenty-five are only accidental visitors. To counteract these possible eliminations there will undoubtedly be several additions made when we shall be better acquainted with our bird fauna.</p>
<p>These notes, besides definitely extending the recorded ranges of many of our North American birds, will show that at least 227 breed within the state and that more than 100 remain within our borders during ordinary winters.</p>

	<p>In response to hypoxic stress, many animals compensate for a reduced cellular O<sub>2</sub> supply by suppressing total metabolism, thereby reducing O<sub>2</sub> demand. For small endotherms that are native to high-altitude environments, this is not always a viable strategy, as the capacity for sustained aerobic thermogenesis is critical for survival during periods of prolonged cold stress. For example, survivorship studies of deer mice (<em>Peromyscus maniculatus</em>) have demonstrated that thermogenic capacity is under strong directional selection at high altitude. Here, we integrate measures of whole-organism thermogenic performance with measures of metabolic enzyme activities and genomic transcriptional profiles to examine the mechanistic underpinnings of adaptive variation in this complex trait in deer mice that are native to different elevations.We demonstrate that highland deer mice have an enhanced thermogenic capacity under hypoxia compared with lowland conspecifics and a closely related lowland species, <em>Peromyscus leucopus</em>. Our findings suggest that the enhanced thermogenic performance of highland deer mice is largely attributable to an increased capacity to oxidize lipids as a primary metabolic fuel source. This enhanced capacity for aerobic thermogenesis is associated with elevated activities of muscle metabolic enzymes that influence flux through fatty-acid oxidation and oxidative phosphorylation pathways in high-altitude deer mice and by concomitant changes in the expression of genes in these same pathways. Contrary to predictions derived from studies of humans at high altitude, our results suggest that selection to sustain prolonged thermogenesis under hypoxia promotes a shift in metabolic fuel use in favor of lipids over carbohydrates.</p>

	<![CDATA[
	<p>We report the draft genome sequence of the red harvester ant, <em>Pogonomyrmex</em> <em>barbatus</em>. The genome was sequenced using 454 pyrosequencing, and the current assembly and annotation were completed in less than 1 y. Analyses of conserved gene groups (more than 1,200 manually annotated genes to date) suggest a high-quality assembly and annotation comparable to recently sequenced insect genomes using Sanger sequencing. The red harvester ant is a model for studying reproductive division of labor, phenotypic plasticity, and sociogenomics. Although the genome of<em> P. barbatus</em> is similar to other sequenced hymenopterans (<em>Apis mellifera</em> and <em>Nasonia vitripennis</em>) in GC content and compositional organization, and possesses a complete CpG methylation toolkit, its predicted genomic CpG content differs markedly from the other hymenopterans. Gene networks involved in generating key differences betweenthe queenandworker castes (e.g.,wingsandovaries) show signatures of increased methylation and suggest that ants and bees may have independently co-opted the same gene regulatory mechanisms for reproductive division of labor. Gene family expansions (e.g., 344 functional odorant receptors) and pseudogene accumulation in chemoreception and P450 genes compared with <em>A. mellifera</em> and <em>N. vitripennis</em> are consistent with major life-history changes during the adaptive radiation of <em>Pogonomyrmex</em> spp., perhaps inparallel with the development of the North American deserts.</p>

	<![CDATA[
	<p>Transgenic corn hybrids that express toxins from <em>Bacillus thuringiensis</em> (Bt) are highly effective against the European corn borer,<em> Ostrinia nubilalis</em> (Hübner), and the closely related Asian corn borer, <em>Ostrinia furnacalis</em> (Guenée). Since the registration of Bt corn hybrids in the U.S. in 1996, there has been a great deal of information generated on <em>O. nubilalis.</em> However, relatively little information exists for <em>O. furnacalis</em>. To help determine whether the information generated for <em>O. nubilalis</em> can be leveraged for decisions regarding the use of transgenic Bt corn against <em>O. furnacalis</em>, experiments were designed to determine whether the pattern of sensitivity to various Bt Cry1 toxins is similar between the two species. Test insects included laboratory-reared <em>O. furnacalis</em> originating from Malaysia, a Bt-susceptible laboratory colony of <em>O. nubilalis</em> maintained at the University of Nebraska-Lincoln (UNL) and an out-group consisting of the sugarcane borer, <em>Diatraea saccharalis</em> (F.), from Louisiana which represents a different genus from the same family. <em>O. furnacalis</em> and <em>O. nubilalis</em> exhibited a similar pattern of susceptibility to all the Cry1 toxins and were highly susceptible to the range of Bt toxins tested including Cry1Aa, Cry1Ab, Cry1Ac and Cry1F. Both of the <em>Ostrinia</em> species were more tolerant to Cry1Ba compared with <em>D. saccharalis</em>, although sensitivity of <em>O. furnacalis</em> was intermediate and did not differ significantly from that of <em>O. nubilalis</em> and <em>D. saccharalis. D. saccharalis</em> was also susceptible to the range of toxins tested but unlike the two <em>Ostrinia</em> species, was more tolerant to Cry1F and more susceptible to Cry1Ba. These results indicate that both of the <em>Ostrinia</em> corn borer species are similar in sensitivity to the Cry1Aa, Cry1Ab, Cry1Ac, Cry1Ba and Cry1F toxins, thus suggesting shared toxin receptors and mechanisms of toxicity for the two species.</p>

<title>DSC enthalpic transitions during starch gelatinization

<description>
	<![CDATA[
	<p>Background: Starch phase transition characteristics were studied by pre-treating starch samples in excess water, dilute sodium chloride and dilute sucrose solutions and subjecting them to differential scanning calorimetry (DSC). Unmodified maize, wheat and potato starches were held at specific temperatures between 30 and 90 °C for 30 min and promptly cooled to 25 °C. Treated samples were then analyzed in situ by DSC. Results: It was found that the progression of the phase transition behavior differed among the three starches and was dependent on the solvent. It was also revealed that phase transition-related enthalpic changes started to occur at low temperatures and that this process involved a continuous sequence of structural changes, resulting in progressive differences in endothermic patterns from low to high temperatures. Conclusion: These findings are in agreement with recent evidence suggesting that starch gelatinization occurs over a wider temperature range rather than as a sudden order–disorder transition taking place within a narrow temperature range. The phase transition mechanism is determined by starch type and solvent combination.</p>

	<p>Accurate assessment of temporal changes in gross primary production (GPP) is important for carbon budget assessments and evaluating the impact of climate change on crop productivity. The objective of this study was to devise a simple remote sensing- based GPP model to quantify daily GPP of maize. In the model, (1) daily shortwave radiation (SW), derived from the reanalysis data (North American Land Data Assimilation System; NLDAS-2) and (2) smoothed Wide Dynamic Range Vegetation Index (WDRVI) data, derived from Moderate Resolution Imaging Spectroradiometer (MODIS) 250-m observations were used as proxy variables of the incident photosynthetically active radiation (PAR) and the total canopy chlorophyll content, respectively. The model was calibrated and validated by using tower-based CO2 flux observations over an 8-year period (2001 to 2008) for one rainfed and two irrigated sites planted to maize as part of the Carbon Sequestration Program at the University of Nebraska–Lincoln. The results showed the temporal features of the product SW*WDRVI closely related to the temporal GPP variations in terms of both daily variations and seasonal patterns. The simple GPP model was able to predict the daily GPP values and accumulated GPP values of maize with high accuracy.</p>

<title>Complex terrain leads to bidirectional responses of soil

	<![CDATA[
	<p>Research on the terrestrial C balance focuses largely on measuring and predicting responses of ecosystem-scale production and respiration to changing temperatures and hydrologic regimes. However, landscape morphology can modify the availability of resources from year to year by imposing physical gradients that redistribute soil water and other biophysical variables within ecosystems. This article demonstrates that the well-established biophysical relationship between soil respiration and soil moisture interacts with topographic structure to create bidirectional (i.e., opposite) responses of soil respiration to inter-annual soil water availability within the landscape. Based on soil respiration measurements taken at a subalpine forest in central Montana, we found that locations with high drainage areas (i.e., lowlands and wet areas of the forest) had higher cumulative soil respiration in dry years, whereas locations with low drainage areas (i.e., uplands and dry areas of the forest) had higher cumulative soil respiration in wet years. Our results indicate that for 80.9% of the forest soil respiration is likely to increase during wet years, whereas for 19.1% of the forest soil respiration is likely to decrease under the same hydrologic conditions. This emergent, bidirectional behavior is generated from the interaction of three relatively simple elements (parabolic soil biophysics, the relative distribution of landscape positions, and inter-annual climate variability), indicating that terrain complexity is an important mediator of the landscape-scale soil C response to climate. These results highlight that evaluating and predicting ecosystem-scale soil C response to climate fluctuation requires detailed characterization of biophysical- topographic interactions in addition to biophysical-climate interactions.</p>

	<![CDATA[
	<p>Pure abstract art has always been controversial. Since the first abstractions of early modernism, to the emotional paintings of abstract expressionists during the mid century, the concrete abstraction of minimalism of the 1960s and recent symbolic abstraction, any apparent retreat from representation has been met with discourse. This consternation has been shared by both the lay public and the informed viewer, for the problems posed by abstraction refer to essential questions about reality while they appear to avoid the real world. But this apparent contradiction between non representation and content has become more obscure as both artists and viewers become more visually sophisticated.</p>
<p>In each of its diverse manifestations, abstraction refers to that which is not seen in the world around us, but felt, imagined, or conceived in the mind of the artist. The viewer must take a leap of faith when contending with a work of abstraction, because the usual methods for corroborating the truth are not applicable. A painting of a bouquet of flowers or a bronze sculpture of a mythological goddess are verifiable subjects. The viewer can recognize them from personal or literary experience. But abstraction exists in a hermetic place, unsullied by worldly assumptions. This inherent isolation from the visible world has continually lent abstraction a mysterious role in twentieth century art. And that which is mysterious is often suspect and sometimes threatening.</p>
<p>The first true abstract paintings were made by Wassily Kandinsky in Russia and Arthur Dove in the U.S., each in about 1910. They were logical evolutions of the late nineteenth century rejection of academic art and its insistence upon placid depictions of the natural world or moralistic interpretations of history. As the culmination of early modernism, the first abstractions embodied the radical imperative to pursue an art which could communicate certain transcendental truths without the mediating elements of narration, symbolism, or retinal mimicry. They were paintings which sought a direct communion with the pure truth of an inner reality, or the reality of another plane. They were the tools with which modernists would establish a new aesthetic for the new century, an aesthetic dependent upon the crucial separation of abstraction from realism.</p>

	<![CDATA[
	<p>Art critic Clement Greenberg described Dan Christensen (1942-2007) as "one of the painters on whom the course of American Art depends." 1 This retrospective exhibition documents Christensen's life-long quest to understand the possibilities of color, paint, and pictorial space. Though long associated with Color Field painting, Christensen's relentless experimentation with style and technique places him among this country's most ambitious abstract and gestural painters.</p>
<p>Christensen was born in Lexington, Nebraska and grew up outside of Cozad. As a teenager Christensen listened to music on radio stations from Shreveport and Little Rock and grew fond of soul, blues, and pop music. His early aspirations to reach beyond his Midwest roots and experience a larger world, coupled with a youthful sense of independence and self-reliance, contributed to his eventual move to New York City. In 1964 he graduated from the Kansas City Art Institute and after one year of graduate school moved to the East Coast where he spent the rest of his life. Although he was painting the figure when he arrived in New York, he soon made an abrupt break from this style.</p>
<p>Artists in Christensen's circle met and shared ideas at Max's Kansas City, a bar on Park Avenue South in New York City. There, Christensen met Minimalist artists Carl Andre and Brice Marden, whom he considered important early influences. Max's is also where Christensen met art dealer Rich8rd Bell8my, who offered to represent him in 1966. Shortly afterward, Bellamy brought art collector and author James Michener for a studio visit. Michener bought a paintingthe first real sale Christensen made</p>

	<![CDATA[
	<p>Synthetic Cubism not only synthesized "real" materials with painted/constructed reality, but also synthesized earlier discoveries, permitting objects to seem tangible while forms and surfaces were shuffled in space as thin as gossamer.</p>
<p>World War I ended the joint investigations of Picasso and Braque and dispersed the international community of artists who had gathered in Paris. Excepting Juan Gris and Ferdinand Leger, all of these artists, including the American artists, were on-lookers. Few grasped all of the issues and formal ideas with which Braque and Picasso experimented. Most seized upon an aspect of the style and wedded it to theories of their own, sometimes political, sometimes purely aesthetic.</p>
<p>Those theories produced Futurism in Italy, Vorticism in Britain, Constructivism and Suprematism in the Soviet Union, De Stijl in Holland. Orphism and Purism were generated by French painters while two Americans in Paris, Morgan Russell and Stanton MacDonald-Wright developed their concept of Synchronism. The work of some of these moved toward pure abstraction, the work of others returned to a more traditional, often figurative art.</p>
<p>Fundamental to nearly all, however, was the use of the facets of Analytic Cubism. Fractured planes served to generate complex, geometric images which frequently were held to be a metaphor for the mechanized and shattered quality of modern industrialized experience. To many parts of this complicated avantgarde profusion of styles the American artist could and did respond. Generally, however, progressive American painters did not, collectively, generate a national style as can be discovered in Russia or Holland. Rather, Cubism in America tends to reflect the diversity of styles produced internationally.</p>

	<![CDATA[
	<p>The Sheldon Memorial Art Gallery and Sculpture Garden is pleased to present Conrad Bakker: Art and Objecthood, an installation that engages many of the most important aesthetic and cultural issues in the contemporary artworld. This exhibition is part of a semesterlong focus at the Sheldon Art Gallery on the significance and influence of Marcel Duchamp, one of the most influential artists of the twentieth century. In addition to this exhibition, the permanent collection galleries of the Sheldon Art Gallery include Duchamp's famous Boite-en-Valise, an etching of his infamous Fountain, and the work of other artists, both historical and contemporary, who have been influenced by this important artist. Finally, I am teaching a seminar in the Department of Art and Art History on Duchamp and his significance on the contemporary artworld, a seminar that will interact with and engage not only the Sheldon's permanent collection, but Art and Objecthood as well.</p>
<p>This exhibition's subtitle, "Art and Objecthood," alludes to several important aesthetic themes. First, it refers to the title of one of the most influential critical essays of the last thirty years, written by Michael Fried in 1967, which argued that the "theatricality" of Minimalism ("objecthood") needed to be defeated through the "absorption" of advanced modernist painting and sculpture (art).l Second, Art and Objecthood refers also to a problem that interested Marcel Duchamp throughout his career, namely, what separates an art object from a non-art object? This concern is seen most explicitly in his "Readymades," in which he explored and exploited the distinction between art object and non-art object. Third, Art and Objecthood also refers to the "objecthood" of art, that is, art's identity as a commodity for consumption among other objects and the socio-political implications of consumer culture.</p>

	<p>A Brief History of Sheldon Statewide</p>
<p>Commemoration-the theme of this year's exhibition-is particularly appropriate, as 2012 marks the twenty-fifth anniversary of Sheldon Statewide. The program began in 1987 as a joint effort of the Sheldon Museum of Art and the Sheldon Art Association, then known as the Sheldon Memorial Art Gallery and the Nebraska Art Association. Conceived as a project of the association's Statewide Committee, chaired by Lois Roskens, it was part of the group's centenary celebrations. From its first exhibition, Miniature Masterworks, Sheldon Statewide has provided opportunities for communities throughout the state to gain access to original works of art. Miniature Masterworks, organized by Sheldon Educator Suzanne Wise, was launched in North Platte, where it succeeded due to the organizational skills of Rhonda Seacrest, the support o,f the North Platte Telegraph and Superintendent of Schools Doug Christensen, and the vigilance of Sharon Skinner. Sheldon docents Nancy Dawson, Lonnie Pierson Dunbier, Phyllis Pauley, Alison Petersen, Jan Roberts, and Ellen Zumwalt worked with local volunteers to provide tours. Over the last quarter century, Sheldon Statewide exhibitions have been viewed in twenty-four Nebraska communities, reached over 275,000 people, and supported additional outreach programs such as Art in Society: Nebraska. Venues have included art galleries, banks, historical museums, and libraries in Chadron, Columbus, Falls City, McCook, North Platte, and Scottsbluff, to name only a few.</p>
<p>The Sheldon Museum of Art wishes to acknowledge the visionary planning of those who first helped to guarantee that the program became a truly statewide endeavor. In Sheldon Statewide's first decade, Nebraska Art Association President Art Thompson, Sheldon Director George Neubert and Curator Daphne Deeds, and museum staff and steady supporters including Nancy Dawson, Lonnie Pierson Dunbier, Karen Janovy, Janice Roberts, and Rhonda Seacrest all helped to guide and shape it. The program has also benefited from the direction of Sharon Kennedy, Susan Soriente, and Sarah Feit. Initial financial support for Sheldon Statewide was provided by the Sheldon Art Association and was renewed in 1992 by UNL Chancellor Graham Spanier. Today, Lonnie Pierson Dunbier, Rhonda and James Seacrest, Farmers Mutual Insurance Company of Nebraska, the Nebraska Arts Council, Nebraska Cultural Endowment, and the Sheldon Art Association support the project. Sheldon Statewide remains a key embodiment of the museum's mission as part of a land-grant institution that is committed "to fostering collaborations within the University and among our constituents in the community, Nebraska, and the nation."</p>
<p>This year's Sheldon Statewide examines commemoration as a theme in art-what brings people together, gives them a sense of identity, and how our perception of commemoration changes over time. Today, for example, Doris Lee's Thanksgiving (fig. 1) seems an endearing and whimsical depiction of a favorite American holiday: a scene of domesticity and tradition in which women and children prepare for the annual family feast in a bustling kitchen. However, the painting actually sparked a firestorm of criticism upon its debut in the 1930s.</p>

<p>As part of the Sheldon Memorial Art Gallery's responsibility and mission to reflect and document the historical development of the visual arts of the United States, we have a commitment to respond to those artists within our own region who contribute to that development. It is within this context that we present Characters: Portraits by Robert Weaver as one of the Sheldon Solo series. Lincoln artist, Robert Weaver, has established a regional reputation for his artistic effort and achievements, but he also has become a well-known "character" because of his artistic independence and personality. This current exhibition focuses on Weaver's recent highly charged and bold portrait paintings of local, powerful and influential individuals that capture the subjects/ personalities with directness and honesty, often revealing the nature of both the artist and the sitter.</p>

	<![CDATA[
	<p>The Sheldon Memorial Art Gallery and Sculpture Garden is pleased to present Sheldon Solo: Carol Haerer, The White Paintings, an exhibition featuring Carol Haerer's white paintings of the mid to late 1960s. This exhibition is the most recent installment of the "Sheldon Solo" exhibition series, a series established in 1988 to feature the work of important American artists within the context of the Sheldon Gallery's nationally recognized collection of 20th-century American Art.</p>
<p>A midwestern native who attended Doane College and the University of Nebraska-Lincoln, Carol Haerer studied in Paris on a Fulbright Fellowship in 1955, and after receiving an M.F.A. from the University of California-Berkeley, she moved to New York. It was in New York where she began to paint intensely subtle white paintings which received considerable critical attention in the late sixties, in part because they seemed to offer a way out of what was perceived by many in the art world to be the straightjacket of Minimalism. But the critical attention they received in the sixties has rarely been noted by art historians, who have tended to evaluate painting or sculpture from this period by the theoretical standards of Minimalism. But as "minimal" as Haerer's paintings appear at first blush, they are images, even atmospheres, but not "objects." This exhibition offers an opportunity for our audience actually "to experience" these paintings as they were intended to be viewed, as an aesthetic environment. We would like to thank Dr. Charles Eldredge, Hall Distinguished Professor of American Art at the University of Kansas and former Director of the National Museum of American Art in Washington, DC for writing the essay for this publication.</p>

	<![CDATA[
	<p>T he presentation of Robert Colescott's groundbreaking solo exhibition, which represented the American Pavilion at the 1997 Venice Biennale, offers a unique opportunity for the Sheldon Memorial Art Gallery and Sculpture Garden to display a selection of African-American art from its permanent collection. This exhibition, entitled Black Image and Identity, serves several important purposes. First, it locates Robert Colescott, one of the most important and influential African-American artists of the twentieth century, within the broader historical context of a dynamic and diverse African-American visual arts tradition. Second, it focuses attention on the important influence that Colescott has exerted on younger artists who have been concerned with racial identity. Third and finally, Black Image and Identity reveals that there is no monolithic, static, and constant set of features called "black identity" but it is in reality subject to constant negotiation and construction. It is the contested and "unstable" status of what constitutes a "black identity" that has challenged artists who have chosen to engage the issue of black identity.</p>
<p>The history of the African-American contribution to national and international culture in the 20th century deserves a much more nuanced treatment than is possible in the scope of this brief essay. But it is useful for the purposes of this exhibition to sketch out at least the outlines of a series of developments as a framework within which Black Image and Identity can be viewed. W.E.B. DuBois's influential book, Souls of Black Folk (1903) attempted to destroy the 19th-century racial stereotypes by emphasizing the presence of a consistent and coherent "black culture." Artists such as Henry Ossawa Tanner contributed to such racial reconceptualization through paintings that communicated the humanity of black family and community life through the cultural idiom of white, middleFig. 3. Michael Rav Charles, While Power, 1994. class Victorian America. These intellectual and aesthetic attempts to articulate a black culture "fully human" formed the foundation for the so-called Harlem Renaissance of the teens and twenties. Over against the "Old Negro" of the 19th century, which dominant culture represented as subservient, always willing to please, and unable to engage serious culture, the Harlem Renaissance participated in reconstituting the "New Negro;' a concept that was both "isolationisF and "integrationist." On the one hand, the Harlem Renaissance focused on the distinct Harlem community as a "black community." On the other hand, the Harlem Renaissance portrayed the black intellectual and artist as fully equipped and capable of interacting and advancing high culture. James VanDerZee's photographs, two of which are represented in this exhibition, communicate quite profoundly the tension of this two-pronged conception of "Blackness," a phrase Richard Powell described as "always signif[ying] more- visually and conceptually--than it has been allowed to represent officially."</p>

<title>The Genocide Archives of the Armenian Patriarchate of Jerusalem</title>

	<![CDATA[
	<p>The Armenian Genocide left behind a plethora of unexamined information in the language of the "victim group." Examining these documents will not only reaffirm the veracity of the historical event, it will also provide historians new ways of understanding, analyzing, and researching the Genocide. The available Armenian sources could be divided into private archives, ecclesiastic archives, diaries and eyewitness accounts, Armenian press articles, and original historical works written by the survivors themselves or prepared by the PanArmenian Unions founded by the dispersed Armenian communities. In the name of academic objectivity, some historians have downplayed the importance of these sources in the reconstruction of the history of the Armenian Genocide. Others have argued that due to the fact that these materials were written by the victim group, they cannot constitute valuable or reliable historical documents because of their lack of objectivity. Following this line of reasoning, some Armenian historians have systematically avoided the use of Armenian sources so that their scholarship would not be labeled as biased by international historians or Turkish scholars. This raises major questions regarding the attitudes of historians in general to Armenian sources. Why should an Ottoman document be more valuable or more authentic than an Armenian one? What makes a document from the Ottoman Archives more authentic than a document from the Armenian Patriarchate of Jerusalem? Why is the story told by the victim group less credible than the one told by the "perpetrator group?"</p>
<p>Despite the fact that such trends exist among scholars, there are other historians who value these sources and use them as part of the reconstruction of the history of the period. Raymond H. Kevorkian's monumental contribution to the history of the Armenian Genocide is one such example. His extensive reliance on the Armenian sources has contributed immensely to our understanding ofthe Armenian Genocide from micro-social, political, and economic perspectives. In addition, his concentration on the process of the Genocide from each and every province to the death camps along the Euphrates and Der Zor route ought to be regarded as an important contribution to understanding the mechanisms of the Genocide and the different processes that contributed to the systematic annihilation of the indigenous Armenian populations of historic Armenia. Another useful source is the history books that were written by Pan-Armenian Unions in the Armenian Diaspora during the post-Genocide period. The main objective of these history-writing practices was to preserve the local identities of the Armenians. Ninety percent of these works were written in Armenian. While one would argue that much of this kind of literature presents a way of mourning their lost homeland, whatever was written during this period is unique since as far as I know there is no popular counterpart mirroring the same period of time in Turkish. Although some of these pieces sound more folkloric/amateur than methodologically sound and historical, it does not undo the fact that they provide invaluable information on the history of the Armenian Genocide. In addition, the Armenian press during the period from the beginning of the War and prior to the formation of the Republic of Turkey should be considered as an important source for understanding the reaction of the remaining Armenian communities within the Ottoman Empire in particular and the Diaspora in general towards the horrendous event. A thorough examination of these newspapers will not only provide vital information about the period but will also shed light on the ways in which Ottoman Turkish society reacted to the Genocide. It is important to mention that many of these rare newspapers are found at the Gulbenkian Library in Jerusalem, which houses the world's third largest collection of Armenian historic newspapers spanning from the 19th to the 20th centuries.</p>

<title>From Bloodless Revolution to Bloody Counterrevolution: The Adana Massacres of 1909</title>

	<![CDATA[
	<p>The historiography of the Adana Massacres of 1909 is represented by two diverging views. While some Turkish scholars deny the involvement of the local government officials in the massacres by putting all of the blame on the Armenians who revolted as part of a conspiracy to establish a kingdom in Cilicia, some Armenian scholars, whose work is overshadowed by the Armenian genocide, accuse the Committee of Union and Progress (CUP) of acting behind the scenes to destroy the Armenian economic infrastructure in Adana in order to curb any future political and economic development in the area. By deviating from the existing historiography, the present article contends that the Adana Massacres should be viewed as part of the revolutionary process which led to the erosion of social and political stability in the region, the creation of weak public-sphere institutions, and intensification of the existing economic anxieties, all of which led to the enactment of violence against the vulnerable Armenian population of Adana. Understanding the factors and the motives that led to the enactment of violence will shed new light on understanding the future acts of violence perpetrated against the indigenous Armenian population of the Ottoman Empire.</p>

	<![CDATA[
	<p>School readiness is determined by the life experiences of young children between birth and enrollment in formal education programs. Early intervention and education programs designed to promote school readiness often focus on skills a child fails to demonstrate that are believed to be of importance to social and academic success. The <em>Getting Ready</em> model of early childhood intervention (Sheridan, Edwards, & Knoche, 2003) recognizes the transactional nature of young children’s development and the important role parents play in pre-school readiness and school-age success. In the <em>Getting Ready</em> model, collaborative partnerships between parents and professionals are encouraged to promote parent’s competence and confidence in maximizing children’s natural learning opportunities, and preparing both parents and children for long-term school success. Parent-child interactions in everyday experiences, mutual observations and goal-directed problem solving, and young children’s successful development constitute the input, processes and outcomes of the <em>Getting Ready</em> model. The empirical rationale for and specific components of the model are described, with practice implications embedded throughout this paper.</p>

	<p>The contrast between the appearance of a work of art which has been professionally restored and one which continues to suffer from at least some of the ills which art can be heir to can seem nearly miraculous, or so subtle as to be invisible to the casually observant eye.</p>
<p>The ills are numerous and reflect the fragility of many if not most works of art. Variations in relative humidity can cause a canvas to shrink or expand. Variations in temperature can do the same. With time and continued fluxations, tiny cracks may appear and grow into fissures that cross the surface of the painting. The paint may actually lift away from the canvas; if the cleavage is sufficiently severe, flakes of paint may fall away from the surface and be lost. Both paint and canvas may become so dry that either can threaten to turn to powder when touched.</p>
<p>The artist may use a stretcher too flimsy for his canvas. The canvas itself may develop draws, sags and buckles, all of which threaten the paint on the surface.Or the artist may use paints and glazes which are chemically incompatible; he or she may use materials that are destined to self-destruct. (As an example, for a large number of drawings, Franz Kline used paper that was expected to last only a year or two: pages torn from a Manhattan telephone directory).</p>
<p>Apart from such inherent vices, a work hands of a viewer reaching to fleetingly explore the actual texture of a surface leave behind a residue of oils and grime. Rings or buttons or fingernails may mar the surface. In time, soil and scratches multiply and the original work becomes defaced. These problems and dozens of combinations and variations the conservator must face. Some difficulties have quick solutions. More usually, conservations and restoration is painstaking business. Compounding the problems themselves is the fact that the contemporary conservator refuses to simply repaint where part of an image is lost. Further, conservation now is done so that it may be reversed. The intent is to recover the artist's intent as fully as possible without supplying counterfeit passages which fuse with and become a permanent part of the work.</p>

	<p>The art of Ed Ruscha has been a consistent and important presence on the art scene since 1960. Yet his works have not received the high visibility media coverage that the work of many of his peers, such as Jasper Johns and Andy Warhol, have garnered. This situation can, in part, be attributed to the fact that contemporary art criticism has tended to center around clearly defined movements, and Ruscha's work has resisted easy categorization. In addition, interpretations of his work have shifted over the past few decades--his work has been cited in discussions of Pop art, Conceptual art and, most recently, strategies of postmodernist appropriation. As a result of this elusive quality, his work has tended to receive only cursory mention in general overviews of the art historical chronology.</p>
<p>Since his emergence on the art scene in the early 1960s, Ruscha's work has evolved and matured. However, the one consistent and most significant aspect throughout his work is the emphasis on the work as the central focus of his art. An understanding of Ruscha's use of the word is critical to a comprehension of his oeuvre. Moreover, his emphasis on the verbal is crucial because it illustrates important issues in the art world during the past three decades. Ed Ruscha's works are thus incisive in their ability to lay bare critical aspects of art production and, reception, and it is this added dimension that lends greater import to his art. In the early years of his career, Ruscha's paintings were closely associated with the Pop art movement of the1960s because of their focus on images from the contemporary urban, consumer-oriented environment. Pop was a pivotal movement in the historical continuum of art in part because of its insistence on figuration, in contrast to the overwhelming predominance of abstraction in preceding and concurrent movements such as Abstract Expressionism, Post-Painterly Abstraction, and Minimal art. Through its content, style, and presentation, Pop art blatantly exposed the commodification of art and of our society in general, and Ruscha's paintings reinforced this.</p>

<title>American Impressionism</title>

	<![CDATA[
	<p>T he term American Impressionism, when used in the context of stylistic analysis, implies a specific set of definable characteristics, and by extension, a traceable lineage that will fit comfortably in the historical narrative of American art. If one seeks to assert this notion when confronted with an exhibition of American Impressionist painters, the result will be confusion coupled with a healthy dose of skepticism. For unlike their French counterparts, who established a style in close proximity to one another, both geographically and philosophically, American artists arrived at Impressionism from a variety of viewpoints.</p>
<p>Early surveys of American art tend to focus only on those American painters who fit comfortably into the accepted perimeters of ERY Girl with Turkeys, Giverny, 1886, oil on canvas the French Impressionist style, specifically the light-suffused, intensely colored, and form dissolving canvases pioneered by Claude Monet. More recently, scholarship has recognized the pervasiveness of certain aspects of Impressionism contained in the work of many American artists of the late 19th and early 20th centuries that is too insistent to be ignored.</p>
<p>In reality, the term Impressionism, even when applied to the French, is only a label of convenience that encompasses a variety of individual styles. Originally it was meant as a derisive nickname applied by an indignant critic to works in the first group exhibition , Societe anonyme des artistes peintres, sculpteurs, graveurs, etc. in 1874. "Impressioniste" was quickly adopted by the French group as being far less unweildy than their original title, while also lending a certain notoriety to their subsequent exhibitions.</p>

	<![CDATA[
	<p>The occasion for the present exhibition, the dedication of the Sheldon Sculpture Garden, marks the completion of one of the most important gifts ever made to the University of Nebraska and to the people of the state. The importance of the gift lies not only in the fact of the distinguished building and the art objects which it houses, but also in the fact of their presence as a potential, a place and a situation where the creative spirit, traditional and activist, may find a laboratory, a workshop and an audience.</p>
<p>The garden is first of all a physical enlargement of the gallery facility, but it is as well an expansion of the interpretive function of the institution as a whole. It is, in fact, the first completed unit in an overall plan for the redesign of the University campus, a plan which will undertake to balance the practical needs of the urban institution with the amenities of the spirit which it represents. In the present instance, the inaugural exhibition undertakes to demonstrate the purpose and value of that plan, not only within the University itself, but as regards the relationship of the institution to the immediate community. It offers an unprecedented opportunity to extend the impact of works of contemporary art beyond the traditional limits of the art gallery and the garden into the context of downtown Lincoln. The random confrontations of daily business will provide a test of some of the ideas current in present day art. These ideas are hardly new, but they nevertheless have taken a form which is peculiarly characteristic of our times.</p>
<p>In a more traditional sense, this will constitute one of the rare occasions on which the history of sculpture in the United States has been taken as a whole as the subject for such an exhibition. Ideally such a conception would be difficult, it not impossible, to realize. The very nature of the material involved is against it. To undertake the project even so, necessitates immediate and continuous compromise and the organizers can only hope to keep within sight of the ideal, representing much by the token presence of important material, suggesting much by implication and taking variable samples of different depth and quantity. If some major achievements are missing, some important figures omitted altogether, we can at the same time call attention to some unknown, forgotten or neglected achievements. Our hope would be, that however much we fail in an encyclopedic sense, we gain, at the same time, a fresh view of the art of sculpture as a gauge of American experience.</p>

<title>American Paintings from the Sheldon Memorial Art Gallery
An Institutional History in Pictures</title>

	<![CDATA[
	<p>The Sheldon Memorial Art Gallery and Sculpture Garden at the University of Nebraska-Lincoln is pleased to present American Paintings from the Sheldon Memorial Art Gallery: An Institutional History in Pictures, an exhibition of more than forty-nine paintings that celebrates an important part of the Gallery's considerable permanent collection, which, for over one-hundred years , has come to define its identity and mission as an art museum. Boasting a permanent collection of nearly 13 ,000 objects , the Sheldon Art Gallery has sought to present the historical development and aesthetic diversity of 19th and 20th-century American art in various media.</p>
<p>But the Sheldon's permanent collection does not only document the history of American art, it reveals the history of the Sheldon Art Gallery as a collecting institution. Since the 1970s, historians, critics, and theorists have directed a considerable amount of attention toward the function of art museums in U.S. culture. Despite the diversity of these views, a common observation has emerged. Far from being a neutral space where works of art are allowed to "speak," art museums actively shape how art communicates to the viewer. Far from being a passive space, the art museum is a proactive space, aggressively shaping our experience of the art it presents, from what art is on view and how works of art are exhibited in relation to others, to the didactic text on the walls.</p>
<p>Art museums with active permanent collections, then, participate in several histories. They participate in documenting and constructing histories of art. But they also are documenting and constructing their own histories as institutions. Works of art in permanent collections not only participate in histories of art, but also in histories of the institution that acquired them. They tell not only of an artist who made them, but of a collector or curator who purchased them or a patron who donated them. As important as the permanent collection is, an art museum is not merely the sum total of the art it cares for and exhibits. It includes the people who acquire it, exhibit it, interpret it; in short, invest their passion in the institution.</p>

	<p>"There is a state of free fall where you don't know up, down, left, right, backwards or forwards; they're totally confused. Those seem to me to be the six ways of orienting yourself. What I would like to do is probably just disorient all those sensations. On the other hand, that also can be a very euphoric state; it can be very pleasing and people engage in all kinds of activities which involve this titillation (skydiving, amusement parks) ... What are they all but ways of titillating yourself? They always have to do with whirling in space, for pleasure as much as for fear;"you make yourself frightened so that you can enjoy it. For me things have that aspect."</p>
<p>And there it is-the most direct way of describing that curious combination of fear and euphoria made immediately apparent in Alice Aycock's sculpture. Like a giant mousetrap, The Machine That Makes The World issues a direct challenge to those who enter-can you make your way through without getting caught? The answer is both yes and no. For unlike the breathless speed of a sky dive or roller coaster ride, The Machine That Makes The World operates very, very slowly. Infinite patience is required to negotiate the complex series of gates and concentric labyrinth. One must wait for each element to gradually reveal an opening to squeeze through.</p>

	<p>Agents of Change: Mexican Muralists and New Deal Artists features works by artists from Mexico and the United States and demonstrates the close ties between them in the 1930s and' 40s. The exhibition is organized into four sections to include Franklin Delano Roosevelt's Works Progress Administration (WPA); the Mexican Muralist Movement; a mural study by WPA artist Lucienne Bloch; and the Taller de Grafica Popular.</p>
<p>Mexican muralism, a government public art initiative, sponsored after the 1910 Mexican Revolution, encouraged social change by depicting the ideals and struggles for independence, while elevating and glorifying the indigenous heritage of Mexico. The Mexican muralists were influential in the United States, especially among young, socially minded artists, many of whom later participated in the WPA. The Guggenheim Foundation further strengthened ties to Mexican art when it offered travel funding to Mexico for artists such as Howard Cook, Doris Rosenthal, and Rico Lebrun.</p>
<p>When Roosevelt took the presidential oath in 1933, he faced a nation immobilized by the Great Depression. Artist George Biddle was the first to step forward for struggling artists. After learning about the Mexican Muralist Movement, Biddle wrote President Roosevelt, a childhood friend and schoolmate, and proposed a similar federal program. Roosevelt's New Deal work relief programs put over 8 million back to work, including thousands of artists on various WPA projects throughout the years of 1933 - 1943</p>

	<p>A canonical transformation relating hard-core and velocity-dependent nucleonnucleon potentials is applied to the Srivastava potential and an equivalent hard-core potential is found. It is shown that the deuteron photonuclear electric-dipole integrated and bremsstrahlung-weighted cross sections resulting from the two equivalent potentials are essentially the same. The reasons for this agreement suggest that differences between the two sets of cross sections may remain small in other nuclei employing this type of potential.</p>

	<![CDATA[
	<p>Sustainability of training lands continues to be a primary concern for natural resource managers on Army installations. Tracked vehicle training, the main disturbance of grasslands, does not occur in isolation from other land uses including cattle grazing. Yet, no documented studies exist examining the interactive effects of these activities on soils and vegetation. The objective of this research was to begin filling this knowledge gap. This report reviews the lit-erature documenting the impacts of tracked vehicle training and cattle grazing on soils and grassland plant communities and discusses potential interactive effects. Responses to tracked vehicle training generally included increased soil com-paction, reduced cover and production of perennial grasses, disturbance of biological soil crusts, greaterwind andwater erosion, and less soil carbon storage. When overstocked, cattle grazing often results in similar effects. Concerns are greatest when heavy stocking results in loss of soil cover and replacement of perennial grassland species with annual grasses and forbs. Overall, the literature suggested that intensive cattle grazing of Army training lands might promote greater soil erosion and less desirable plant communities. The consequences of their interaction is likely to be greater in arid grasslands, where recovery mechanisms are slow and desertification is a concern.</p>

	<![CDATA[
	<p>Introductory treatments of relativistic dynamics rely on the invariance of momentum conservation (i.e., on the assumption that momentum is conserved in all inertial frames if it is conserved in one) to establish the relationship for the momentum of a particle in terms of its mass and velocity. By contrast, more advanced treatments rely on the transformation properties of the four-velocity and/or proper time to obtain the same result and then show that momentum conservation is invariant. Here, we will outline a derivation of that relationship that, in the spirit of the more advanced treatments, relies on an elemental feature of the transformation of momentum rather than on its conservation but does not have as a prerequisite the introduction of four-vectors and invariants. The steps in the derivation are no more involved than in the usual introductory treatments; indeed, the arithmetic is almost identical.</p>

	<![CDATA[
	<p>Researchers monitored the threatened plant, purple amole (Chlorogalum purpureum var. purpureum) at Fort Hunter Liggett, California, from 1998 to 2004. The objectives of this research were to complete a statistical analysis of these data to evaluate: (1) demographics; (2) trends in population density; and (3) the relationship of purple amole to associated species, biological soil crusts, and disturbance. Overall, purple amole was most likely to flower and have greater seed production when it attained about 8 leaves or widths of 7 to 8 mm for its widest leaf, revealing a clear relationship between plant size and successful reproduction and seed set. Mortality and dormancy rates were estimated at 10 and 23 percent per year, respectively. Presumably, dormancy occurred, as mapped individuals were absent periodically throughout the monitoring. Density of purple amole was positively correlated with native species and presence of biological soil crusts; relationships to disturbance type were not apparent. Power analyses revealed that purple amole should be monitored at least 10 years to detect increases or decreases of 10 percent for mature plants (4 or more leaves). Due to greater variability, 10 to 20 years of monitoring are recommended to detect similar changes for 1 to 3-leaved plants.</p>

	<p>Military training often results in environmental degradation that has negative impacts on future training missions. The U.S. Army Construction Engineering Research Laboratory (CERL) conceptualized the Army’s Integrated Training Area Management (ITAM) program in response to the concerns expressed by military land managers and trainers over the declining condition of training and testing lands. ITAM has evolved to include land condition and trend analysis (LCTA), environmental awareness (EA), training requirements integration (TRI), and land rehabilitation and maintenance (LRAM). The need for LRAM has increased dramatically over the past decade. Among the many difficulties faced in planning and implementing a land rehabilitation project is procurement of appropriate plant materials for revegetation of damaged lands. To satisfy government procurement requirements and ensure a fair and reasonable price for materials, it is usually necessary to identify and solicit bids from multiple vendors. Moreover, there is an increasing emphasis on the use of locally endemic or adapted plant species. These factors increase the demand to identify multiple commercial sources of regional or local sources of plant materials. This research compiled a comprehensive, current list of plant material vendors, including vendors of trees, shrubs, grasses, wild-flowers, and wetland plants.</p>

	<p>To advance the field of children’s services, implementation and generalization studies are needed to help us reveal the inner workings of intervention projects and how they do (or do not) achieve their outcomes. This paper provides a case study of Head Start teachers’ uptake of the <em>Getting Ready</em> school readiness intervention, intended to strengthen professionals’ capacity to support parental engagement in young children’s development and learning. The qualitative method of document review was used in scrutinizing home visit reports and classroom newsletters as a source of authentic evidence about teachers’ implementation and generalization of an early intervention model. Home visits were a focus of training and coaching, and the analysis provided strong evidence of treatment group teachers implementing <em>Getting Ready</em> strategies of collaborative planning and problem-solving with parents around academic learning and social-emotional goals. In contrast, newsletters were not the focus of the intervention; their analysis provided clear evidence of spontaneous change (hence, generalization) made by teachers on their own as they sought to strengthen home-school collaboration, form strong and trusting relationships, and spotlight and acknowledge child and parent competence. Beyond finding evidence of teachers’ uptake and generalization of the <em>Getting Ready</em> strategies, the study suggests the utility of analyzing teachers’ everyday documents to uncover patterns of behavior change of teachers seeking to implement an early childhood school readiness intervention.</p>

	<p>Military training can often be destructive to the environment. Environmental impacts associated with heavy training include soil compaction, soil erosion, siltation of waterways and wetlands, increased threat of flooding, loss of wildlife habitat, declining biodiversity, and invasion by noxious weeds. Planning and implementing land rehabilitation projects generally involves some soil movement, establishment of vegetation, stabilization and hardening of sites, etc. Procurement of appropriate heavy equipment and other specialized equipment is sometimes a difficult task that involves obtaining multiple vendors, especially when procuring equipment for rental, lease, or purchase. This report and associated database were created to help land managers easily identify and obtain potential vendors for the equipment needed for land rehabilitation projects. This report includes a comprehensive and up-to-date list of heavy equipment vendors within the United States, primarily for rental or leasing purposes, which includes vendors of construction, agriculture, and other equipment needed for erosion control, and land rehabilitation and maintenance. Volume I of this report lists vendors located within 100 miles of Army installations, and National vendors. Volume II lists all vendors state-bystate.</p>

	<p>There is limited information available explaining the agronomic and economic relationships between yield and nitrogen and phosphorus applications to growing switchgrass produced in phosphorus-deficient soils. The objective of this study was to determine the effects of nitrogen and phosphorus fertilizers on feedstock yield and measures of expected total cost, gross revenue, net return, and breakeven price of feedstock produced in phosphorus-deficient soils in the southern Great Plains. Data were collected from a three-year, two-location agronomic field study conducted in south-central Oklahoma. Two discrete nitrogen treatments (0 and 134 kg ha<sup>-1</sup>) and four discrete phosphorus treatments (0, 30, 60 and 90 kg ha<sup>-1</sup>) were randomly assigned to small plots arranged in a randomized complete block designed (RCBD) study. Random effects mixed ANOVA models were used to estimate the effects of nitrogen, phosphorus and nitrogen by phosphorus interactions on feedstock yield and the economic variables specified. Results showed that, on average over site-years, switchgrass yield increases from 10.5 to 12.3 Mg ha<sup>-1</sup> with the highest (101-kg ha<sup>-1</sup>) treatment; however, we found no statistical difference in net profitability between phosphorus treatments. Yield and net return did respond significantly to 135 kg<sup>-1</sup> of N ha<sup>-1</sup>. Our results suggest that phosphorus-deficient soils do not seem to have the same impact on switchgrass yield and profitability as they do for the yields and profitability of other crops traditionally grown in this region.</p>

	<p>Stocker cattle grazing warm season perennial grasses is an important economic activity in the southern Great Plains. Substantial increases in the price of nitrogen fertilizer is negatively affecting forage producers‟ profitability. Two alternative nitrogen management systems that use annual and perennial legumes have been developed for bermudagrass pastures. The goal of the study is to determine if the legumes systems are more profitable than the conventional practice of applying synthetic sources of nitrogen. Results of the two-year grazing study show that the legume systems could not compete economically with the common practice.</p>

	<![CDATA[
	<p>Switchgrass (<em>Panicum virgatum L.</em>) has been targeted for cellulosic ethanol production. Our objective was to evaluate effects of <em>P</em> and <em>K</em> fertilization on switchgrass biomass yields. Experiments were established in switchgrass (cv. <em>Alamo</em>) fields planted at three Oklahoma locations in 2007. Interactions of <em>N</em> and <em>P</em> fertilizer rates were evaluated on two sites that had low soil test <em>P</em> (6 to 9 kg/ha). Interactions of <em>N</em> and <em>K</em> fertilizer rates and harvest system were evaluated on a site that had low soil test <em>K</em> (134 kg/ha). In the <em>N</em> and <em>P</em> rate experiments, biomass yields during establishment were unaffected by treatments, averaging 2145 kg/ha in 2007. During 2008, main effects of location, <em>N</em>, and <em>P</em> rate were significant. Application of 134 kg N/ha increased yields from 7945 to 9967 kg/ha. Applying 101 kg P2O5/ha increased yields from 8528 to 10242 kg/ha. In the harvest system, N, and K rate experiment, biomass yields were unaffected by treatments in 2007 and 2008, averaging 4603 and 16145 kg/ha, respectively. Cutting biomass twice per year as opposed to once a year, however, removed more <em>N</em>,<em>P</em>, and <em>K.</em> Uptake of <em>N</em>, <em>P</em>, and <em>K</em> averaged 216, 24, 209 kg/ha within the two-cut system and 133, 13, and 36 kg/ha, within the one-cut system, respectively. Although low soil test <em>P</em> and <em>K</em> did not strongly limit biomass yields of these young stands, continued biomass harvesting and removal without nutrient replacement has the potential to mine soil of nutrients and constrain biomass yields as stands age.</p>

	<p>Guretzky specializes in research on forage and bioenergy crop management that will assist agricultural producers and landowners in meeting their goals. The first area of research involves Drs. Jon Biermacher and Billy Cook for the evaluation of management practices of switchgrass in forage and bioenergy systems. Objectives include: 1.) assessing potential on-farm biomass yields and production economics of switchgrass; 2.) documenting effects of location, harvest system and nitrogen fertilizer rates on biomass yields, forage quality, stand persistence and nutrient removal rates; 3.) evaluating establishment and biomass production responses to phosphorus and potassium fertilization; 4.) determining how stocker cattle gains on switchgrass vary with stocking density; 5.) determining switchgrass persistence and end of season biomass yields following early season grazing; and 6.) determining economics of stocker cattle ownership on switchgrass.</p>
<p>The second area of collaborative research involves Drs. Twain Butler, Ryan Reuter and Jon Biermacher and focuses on evaluation of legume species in pastures. Research objectives include: 1.) evaluating spring forage availability of winter annual legume species; and 2.) documenting net returns to land, labor and management from stocker cattle grazing N-fertilized and legume-interseeded pastures. Results have been promising. From 2006 to 2008, hairy vetch and Austrian winter pea produced dry matter yields ranging from 2,204 to 6,720 lb/acre across six environments. In 2008, a grazing experiment was established to compare bermudagrass fertilized with urea at 112 kg N/ ha; bermudagrass interseeded with a grazingtype alfalfa; and bermudagrass interseeded with a mixture of winter annual legumes (hairy vetch, crimson clover and arrowleaf clover). Net returns were $292, $109 and $227/ha for N-fertilized, alfalfa and annual legume systems, respectively. Net returns between the N-fertilized and the annual legume system were sensitive to price of N, gain/ha, value of gain and grazing days.</p>
<p>The third area of research evaluates the use of fire to improve rangeland for beef cattle and wildlife. In collaboration with Ken Gee and others, research at the Oswalt Road Ranch will examine how controlled burning affects stocker cattle production, herbaceous and woody species composition and biomass, and land management economics. Three experimental units will be controlled burned and grazed, and three will receive grazing only. Annual changes in herbage mass and plant communities will be documented beginning in 2009 and prescribed burning and grazing will continue until 2020.</p>

	<p>On March 31, 2009, a draft discussion of the American Clean Energy and Security Act of 2009 was released to the public. The bill contains four sections addressing:  <ol> <li>clean energy;</li> <li>energy efficiency;</li> <li>reducing global warming pollution; and</li> <li>transitioning to a clean energy economy.</li> </ol></p>
<p>Section 3 contains a description of the proposed cap-and-trade program designed to reduce industrial emissions of greenhouse gases (GHG) including carbon dioxide (CO<sub>2</sub>), methane (CH4), nitrous oxide (N<sub>2</sub>O), hydro-fluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6) and nitrogen trifluoride (NF3). Agricultural sources, although largely diffuse and not regulated directly by the bill, account for 8 percent of U.S. annual GHG emissions (U.S. EPA, 2008). The agricultural community can address climate change by reducing its emissions and adopting management practices that enhance storage of carbon in soil. The objective of this article is to describe the effects of grazing land management on soil carbon storage.</p>

	<p>Recently, our agricultural research team has been asked to provide talks during tours of our Oswalt Road Ranch. The Oswalt Road Ranch is a 4,992-acre property in Love County, Okla., willed to us by D. Joyce Coffey. The Noble Foundation took full control of the property in 2000. The ranch is a valuable piece of property because of its unique natural beauty and potential to support livestock production and wildlife habitat. On the tours, we have been showing off our new state-of-the art livestock handling facilities and providing information about results from recent research on by-product feeds, the Noble Foundation stocker cattle receiving program, white-tailed deer movements and management of rangelands.</p>
<p>As a forage agronomist, I am involved in our current and future plans for the management of the range and forestland covering this property. Today, I'm going to tell you more about this property, explain why it has unique value as a native ecosystem, illustrate how it fits as a component of the natural heritage of Oklahoma, and discuss our plans for managing this property to enhance its value for wildlife and cattle, while hopefully providing some insight on how you might manage similar properties.</p>

	<p>Legumes can improve the production and nutritional value of pastures while reducing nitrogen fertilization requirements. On July 19, 2008, the Noble Foundation will host the "Texoma Pasture Conference" to explain the pros and cons of using legumes in pastures. The Agricultural Division has invited experts from Alabama, Georgia, Kentucky, Oklahoma and Texas to deliver this exciting program. We encourage you to attend this timely event. In the meantime, we will tell you about ongoing research in the Agricultural and Forage Improvement divisions evaluating legumes for pasture.</p>
<p>A goal of our research is to identify best practices for establishing and managing cool-season or temperate forage legumes in winter and summer pasture systems. Besides increasing nitrogen availability through atmospheric nitrogen fixation, temperate legumes can help bridge a gap between winter and summer pastures. Optimum growth and availability of temperate legumes occur during spring, a time in which the quality of winter small-grain pastures is declining and bermudagrass is yet unavailable. In 2006, we initiated research at three regional sites to determine forage yields of different legume species. The following is a description of common legumes included in our trials and their use as forage in southern pastures.</p>

	<p>In the 2006 State of the Union Address, President George W. Bush proposed the Advanced Energy Initiative to reduce U.S. dependence on foreign oil through accelerated development of domestic, renewable alternatives to gasoline and diesel fuels. A goal of the initiative was to make ethanol derived from cellulosic biomass (crop residues, fast-growing trees and grasses) cost competitive with grain ethanol by 2012. Transportation fuels derived from cellulose - the fibrous material of plants - offer an attractive alternative as an abundant, domestic and renewable resource.</p>
<p>The U.S. Department of Energy identified switchgrass as a model cellulosic crop because it combined more attributes desirable for bioenergy production than other grasses. Among these attributes, switchgrass was a seeded, perennial grass native throughout North America. It was widely distributed and productive across a wide geographical range.</p>
<p>In research at Ardmore, we have found biomass yields of switchgrass (cultivar "Alamo") to average 6.5 tons per acre. Multilocation experiments were initiated in 2007 to evaluate the response of switchgrass to nitrogen, phosphorous and potassium fertilization rates, and biomass harvesting. Data is limited or sometimes nonexistent on biomass yields of other perennial grasses for bioenergy production in Oklahoma.</p>

Switchgrass is a native range and pasture grass that has been identified by state and national leaders as a potential crop to be grown, harvested and converted into ethanol. Slow seedling establishment has previously limited adoption of switchgrass in forage production. Presently, scientists in the Noble Foundation's Agricultural and Forage Improvement divisions are researching ways to improve switchgrass establishment. Here is what we know, and don't know, about the process.</p>

	<![CDATA[
	<p>Switchgrass has future potential in the Southern Plains as a dedicated cellulosic biofuels crop. In the near and intermediate terms, an economically viable use for switchgrass needs to be found. In May 2007, the Noble Foundation Agricultural Division successfully established a 30-acre field of switchgrass at the Red River Demonstration and Research Farm. Beginning in April 2008, we will evaluate the utilization and value of switchgrass for stocker cattle. Switchgrass may have value for stockers because of its early spring availability, high yields, perennial life form, wide adaptability and low fertilization requirements.</p>
<p>Second-year stands of switchgrass become available for grazing near April 15. To enhance growth and nutritive value, we recommend fertilizing switchgrass stands with nitrogen at 50 to 100 pounds per acre. Intensive early stocking with young growing cattle from April 15 through June 15 could take advantage of the early season period of rapid growth and associated young, high quality plant tissue. Under such management, we recommend that switchgrass not be grazed from July through November. The rest period will allow switchgrass enough time to recover leaf area and store energy reserves by fall. Alternatively, one could manage switchgrass with a continuous, season-long stocking at a moderate rate with beef cows from late April through September. Such management has been practiced for years on native range.</p>

	<![CDATA[
	<p>To be a self-contained theory, topological particle theory should explain from the basis of its own stated framework of assumptions (nonlinear self-consistency equations, pole factorization, crossing symmetry, and Hermitian analyticity} all the mathematical properties and numerical values of scattering amplitudes. This paper attempts to move the theory in this direction by showing that the phases of the zero-entropy amplitudes in the theory are, in fact, determined by the above framework of assumptions except for trivial ambiguities that appear to have no physical consequences. This extends previous work on this subject and removes the need for certain extra assumptions. Once the results in this paper have been established it can be shown that the conventional connection between spin and statistics as well as parity, time-reversal, and charge-conjugation invariance in strong interactions also follow from the above framework of assumptions. These latter results will be fully discussed in the following paper.</p>

	<![CDATA[
	<p>A new formulation of nonrelativistic scattering theory is developed which expresses the <em>S</em> matrix as a path integral. This formulation appears to have at least two advantages: (1) A closed formula is obtained for the <em>S</em> matrix in terms of the potential, not involving a series expansion; (2) the energy-conserving <em>δ</em> function can be explicitly extracted using a technique analogous to that of Faddeev and Popov, thereby yielding a closed pathintegral expression for the <em>T</em> matrix. The introduction of the concept of the classical interaction picture provides considerable physical insight into this formulation. This formulation also suggests a successionof improvements to the eikonal approximation, the first of which is discussed explicitly.</p>

	<p>This article analyses the awarding of the Royal Society’s Copley Medal to James Prescott Joule (1870), Julius Robert Mayer (1871) and Hermann Helmholtz (1873) in the wake of the establishment of the law of conservation of energy during the 1850s and 1860s. It seeks to reconstruct the context in which the awards occurred, emphasizing at once a combination of individual scientific achievement, advocacy on behalf of Joule’s supporters, nationalism, and the special role that Helmholtz played thanks to the strong social relationship that he had developed with the British scientific elite in the two decades before receiving his award, the last of the three. The award in turn strengthened that relationship, as the great subject of discussion in physics now gradually turned from thermodynamics to electromagnetism and to reaching practical agreements in electrical metrology between the British, the Germans and others.</p>

	<![CDATA[
	<p>For the Armenians of Palestine, the three decades of the Mandate were probably the most momentous in their fifteen hundred-year presence in the country. The period witnessed the community’s profound transformation under the double impacts of Britain’s Palestine policy and waves of destitute Armenian refugees fleeing the massacres in Anatolia. The article presents, against the background of late Ottoman rule, a comprehensive overview of the community, including the complexities and role of the religious hierarchy, the initially difficult encounter between the indigenous Armenians and the new refugee majority, their politics and associations, and their remarkable economic recovery. By the early 1940s, the Armenian community was at the peak of its success, only to be dealt a mortal blow by the 1948 war, from which it never recovered.</p>

<title>Constructive Developmental Theory:
An Alternative Approach to Leadership</title>

	<![CDATA[
	<p>As early as 1954, the critical value of leadership in dietetics was described by Rourke, who wrote, “When the day comes that your executive abilities equal your scientific knowledge, your profession (dietetics) will be secure. Until that day, you will be faced with a constant and unwelcome challenge” (1). Career and leadership skills development have been identified as an area for further attention by American Dietetic Association (ADA) practitioners and student members (2). Creation of the ADA Leadership Institute in 2003 represented an awareness of the need to invest in developing dietetic leaders (3). Proficient leaders are critical in keeping our profession on the cutting edge by identifying areas of need for change and providing leadership for change. Proficient leaders can also serve as role models for members.</p>
<p>Leadership has been identified as essential for success in the 21st century and according to Bennis, “our quality of life amidst the volatility, turbulence and ambiguity of our present day societal context, depends on the quality of our leaders” (4). Leadership research theory has been based on objective measures such as traits, attitudes and performance, intellect, personality, relationships, competencies, and values. Dietetic leadership studies are limited and describe these objective characteristics and leadership styles (5-9). In their review of traditional leadership theory, Gregoire and Arendt (10) suggested that more information is needed about how dietitians develop as leaders. The present article describes one theory of leadership development—constructive developmental theory. Registered dietitians at advanced leadership stages can be identified and factors enabling their development can be studied. This theory provides a subjective approach for studying dietetic leadership and gives insight for leadership development programs.</p>

	<![CDATA[
	<p>Consumption of long-chain n-3 polyunsaturated fatty acids (n-3 PUFA) is low among certain population subgroups in the United States, especially in people living in Midwestern states and those who dislike fish. Therefore, there is a need to identify acceptable food sources of n-3 PUFA. Vegetable oils, such as canola and soy, provide some n-3 fatty acids. However, these sources are high in n-6 fatty acids and there is concern that they may have detrimental side effects. Eggs enriched in n-3 PUFA can be produced by incorporating sources of these fatty acids into poultry rations. In acceptability studies, US consumers responded positively to n-3 enriched eggs. However, Americans may be reluctant to consume eggs as a source of n-3 PUFA because of their cholesterol content.</p>
<p>The purpose of this study was to evaluate the effects of the addition of LNA- and DHA-enriched eggs on serum lipids of people with hyperlipidemia who were consuming a low-fat diet.</p>

	<p>This article describes Bridgewater State College's Center for the Advancement of Research and Teaching (CART). CART's role is to prepare all faculty and librarians to take advantage of the opportunities that the new Center for Tecyhnological Applications will make available for the teaching and learning process, not only for students but for faculty. The challenge for CART is to integrate traditional faculty development with technological training as one more tool for the practitioner to enhance teaching and learning. Bridgewater's program has successfully attracted faculty to educational technology, encouraged teaching and research projects through a summer small grants program, and built a sense of faculty ownership in the Technology Center.</p>

	<![CDATA[
	<p>The primary function of institutions of higher education is to facilitate learning. New faculty are hired yearly with the expectation that they will match student needs with effective learning experiences. But many incoming faculty, although knowledgeable in their fields, enter higher education with limited preparation or experience in teaching. This can reduce the effectiveness of the teaching/learning process. The question is: "How can faculty with limited teaching experience be helped to strengthen their teaching effectiveness?" To examine this question, this article will describe the development, implementation, and qualitative and quantitative assessment of an innovative faculty development program entitled "Teaching the Technology of Teaching" (TIT).</p>

	<p>This last section combines perspectives of both organizational development and personal development. Those of us who have been in faculty development a long time remember when we were defining the role faculty developers "should" play on our campuses. At the same time the subject of the "career" of a faculty developer was also discussed, often with some puzzling overtones. The passage of time has helped faculty development clarify both the role-or many roles-faculty developers play and the career paths each might follow.</p>

	<p>The editors have chosen to offer the two essays in this section by themselves because we want to underline the importance of a vital task calling us as change agents and community builders. 0. Scott Peck (1987) in <em>The Different Drum</em> writes that the "great enemy of community is exclusivity" (p. 61). We can point to egregious examples of exclusion in our society; but can we clearly see how we ourselves practice exclusivity, even with the best of intentions? If we do recognize the problem, how can we not only change our own behaviors but also promote inclusion across our campuses?</p>

	<![CDATA[
	<p>This volume of <em>To Improve the Academy</em> begins with essays examining different groups of faculty within our institutions. We clustered these together because each spotlights a special group of faculty. One danger in institutions of higher learning is that the term "community" may be misused. It could be restricted to an academic department that must get along by reason of budgets, proximity of offices, or shared parking lots. Or the term could be a convenient designation for a group of people sharing a category-such as the "research faculty." Or it could be used to disguise problems within or between campus groups. Authors of each of the articles in this section identify a group of individuals who may or may be members of only a superficial community. In each case, the essays exemplify the role faculty development can play in assisting individuals to become truly members of the academic community.</p>

	<p>Faculty Development is an emerging field for institutions of higher education; therefore, the procedure for recruiting center directors and faculty developers has not been carefully examined or published. Constructing or reviewing resumes, curriculum vitae, or application portfolios is still an uncharted area in our profession. Information about these procedures is currently available only in the experiences of employers and potential employees for positions in faculty development. The objective of this article is to begin the process of accumulating useful criteria for employees and employers to find the right match of needs and qualifications. As a unique field in the academic setting, faculty development demands more specific guidelines for the job application process.</p>

This article (1) outlines the key attributes of groups affecting their ability to engage in productive work, (2) identifies management practices that have consistently resulted in high performance teams in the workplace, (3) compares these practices with the prescriptions of three widely used but different instructional approaches to group-based learning: incorporating a group assignment as a supplement to a predominantly lecture-based course, Cooperative Learning and Team Learning, and (4) discusses the implications for using small group-based instructional strategies in higher education.</p>

	<![CDATA[
	<p>This article reports on a study of issues of faculty isolation and morale in mid-career faculty. Interview questions probed the dynamics of individual careers and asked about the quality of work life in the department and university, and changes in work life over the course of careers. Findings suggest that a majority of faculty, regardless of professional interests or scholarly prestige, would like greater interaction with departmental colleagues, more recognition from their department and university, a reward system based less on outside offers, and more fluid communications with upper-level administrators. Faculty comments clearly illustrate the advantages of an academic career: the autonomy and freedom to pursue one's own interests and set one's own priorities; the ability to have several "careers" in the course of a single faculty career. Findings suggest that faculty needs vary substantially with career stage and that effective faculty development programs will be responsive to this variation.</p>

	<p>This article describes recent initiatives designed to audit and assess the quality of education in British universities. Such concerns are not new and have been addressed in various ways, including the accreditation of programs by professional bodies and of programs and institutions by regional accreditation/validation bodies. In essence these initiatives, old and new, seek to provide assurance, to the academy and to the public, that standards are appropriate, satisfactory, compatible with objectives, and broadly comparable between similar programs or institutions. At present, there is a gathering international movement toward requiring universities to produce evidence about their systems of quality assurance and control. Paradoxically, while these requirements place additional demands upon the academy, they offer new opportunities for faculty developers.</p>

	<![CDATA[
	<p>Faculty development programs have been at the forefront for the last decade in confronting new issues related to teaching and learning. These collective efforts have encouraged faculty to engage more directly and more deeply with students and ideas. Central to each of these efforts has been self-reflection and thoughtful analysis of the issues. Sexual orientation has not been a significant part of that personal study or dialogue. For those of us committed to strengthening our academic communities, recognizing this exclusion of the gay, lesbian, and bisexual community demands that we work to reduce the barriers. This will mean a renewed commitment to faculty development efforts that enhance the teaching and learning environment for all. While the issue is complex and the questions are difficult, there are a number of beginning strategies that faculty development specialists can use in taking a proactive role.</p>

	<p>This article describes strategies to help novice faculty developers successfully adjust to their new profession and be effective in what they do. These approaches suggest that new developers may be better informed than they think they are, but will need to be prepared to make choices about what they do; deal with the challenge of limited resources; anticipate the unexpected; and recognize that their office may be perceived by faculty members as a safe place. Differences between the roles of faculty member and faculty developer are indicated. Additional suggested strategies include using publications, making the faculty development office visible, keeping higher administrators informed, building strong relationships within the academic community, and taking advantage of such organizations as the Professional and Organizational Development Network in Higher Education (POD) and the Society for Teaching and Learning in Higher Education (STLHE). The author suggests that effectiveness in faculty development can contribute to the building of community in the academy.</p>

	<p>Switchgrass (Panicum virgatum L.) has been targeted for cellulosic ethanol production. Our objective was to evaluate effects of location, harvest system, and N fertilizer rates on switchgrass biomass yield and N, P, and K removal. Randomized complete block experiments with four replications were established on one-year old stands of ‘Alamo’ switchgrass at two Oklahoma locations in 2008. Harvest system and N rate interactions affected total annual yield. Biomass yields ranged from 9020 to 10530 kg/ha across harvest systems when no N was applied. With application of 179 kg N/ha, biomass yields averaged 10715, 13912, and 16516 kg/ha when harvested at seed maturity (October), after a killing frost (December), and twice per year at boot stage (July) and after a killing frost, respectively. Nutrient removal tended to increase with N fertilization and was generally twice as great for each nutrient within the two-cut system relative to the one-cut systems. When 179 kg N/ha was applied, N removal was 198, 82, and 122 kg N/ ha when cut twice, cut once at seed maturity, and cut once after frost, respectively. Phosphorus removal was 22, 12, and 11 kg/ha among these systems, respectively. Corresponding K removal was 203, 62, and 25 kg/ha. Applying N and harvesting once after frost ensures both high biomass production and reduces soil nutrient mining. Total biomass harvest, however, was greatest under the two-cut system, enabling a potential use of switchgrass early in the season for forage and availability of regrowth for bioenergy purposes.</p>

	<p>INTRODUCTION</p>
<p>Rising costs of N fertilizer coupled with evidence of improved forage production and quality has increased interest among beef cattle producers in legume-grass mixtures for pasture. Our objectives were to evaluate forage yields of temperate legumes seeded with perennial grasses in the Southern Plains. Replicated field trials were established in 2006 at Burneyville, OK; Vashti, TX; and Stephenville, TX, to evaluate potential legume dry matter (DM) yields under different soil and rainfall regimes.</p>
<p>MATERIALS AND METHODS</p>
<p>Burneyville. Legumes were broadcast-seeded and lightly raked by hand within individual 3 x 5 m plots in an existing stand of eastern gamagrass (<em>Tripsacum dactyloides</em>) on 25 Sept. 2006. Before seeding, the eastern gamagrass stand was mowed and baled to a 20- cm height. Diammonium phosphate was applied at 112 kg ha<sup>-1</sup> on 3 Nov. 2006. Cumulative legume forage yields were determined by harvest of two 0.1-m<sup>2</sup> quadrats at a 2.5-cm height between the eastern gamagrass rows on 19 April, and 27 June 2007. Vashti. Legumes were seeded at < 6.0-mm depth with a HEGE 500 drill into a clean-tilled seedbed along with ‘Flecha’ tall fescue (<em>Festuca arundinacea</em>) at 17 kg PLS ha-1 on 4 Oct. 2006. Before planting, diammonium phosphate was incorporated into the soil at 112 kg ha-1. Grass and legume DM yields were determined by harvest of two 0.4-m<sup>2</sup> quadrats at 2.5-cm height on 23 Mar. 2007. Plots were grazed from April through May 2007 to allow for estimation of reseeding and persistence in spring 2008. Stephenville. Legumes were seeded in individual plots at < 6.0-mm depth with a HEGE 500 drill into an existing switchgrass (<em>Panicum virgatum</em>) stand on 31 Oct. 2006. Before seeding, the switchgrass stand was mowed to a 5-cm height, and triple superphosphate was applied at 112 kg ha<sup>-1</sup>. Forage DM was measured by clipping two 0.4-m<sup>2</sup> quadrats at 2.5-cm height from each plot when each legume species reached 50 percent bloom. The trials were randomized complete block designs. Treatments were replicated four times, and data were analyzed with the GLM procedure in SAS (Statistical Analysis Software, Cary, NC). Significance was determined at P < 0.05.</p>

	<![CDATA[
	<p>Stocker cattle grazing warm season perennial grasses is an important economic activity in the southern Great Plains. Substantial increases in the price of nitrogen fertilizer is negatively affecting forage producers’ profitability. Two alternative nitrogen management systems that use annual and perennial legumes have been developed for bermudagrass pastures. The goal of the study is to determine if the legumes systems are more profitable than the conventional practice of applying synthetic sources of nitrogen. Enterprise budgeting techniques were employed to compare the economics of the legume systems relative to the common practice. Results of the two-year grazing study show that the legume systems could not compete economically with the common practice. The perennial legume system was most sensitive to the expected life of the stand and the number of grazing days.</p>

	<p>Introduction</p>
<p>Livestock and forage production are the largest contributors to agricultural income in the primary service region of the Noble Foundation. The small grains variety testing program which includes oats, rye, triticale and wheat is designed to provide up-to-date performance information to producers in Oklahoma and Texas about varieties that are commercially and commonly available. In addition, the program provides a tool to evaluate and compare experimental breeding lines emerging from the Noble Foundation breeding program as well as other public and private breeding programs. The program is intended to furnish producers with supplemental information and to aid decision-making and idea formation. The information coming from the variety testing program should be a valuable tool when used with similar information from other sources. The objective of this report is to summarize forage and grain yields from the 2008-2009 small grains variety trials.</p>
<p>Materials and Methods</p>
<p>The small grains variety trials were conducted at the Noble Foundation Dupy Farm (Dale silt loam) near Gene Autry and the Red River Demonstration and Research Farm near Burneyville, Okla. The experimental design was a randomized complete block with three replications. The experimental unit is a 5- by 10-foot plot of a single variety. The trial consisted of 30 entries of wheat, 10 entries of oats, 14 entries of rye and 12 entries of triticale that were evaluated during the 2008-2009 crop growing season. The entries were seeded in a clean-tilled seedbed on Oct. 1, 2008, at the Dupy Farm (Dupy) and on Sept. 29, 2008, at the Red River Demonstration and Research Farm (Red River). Depending on the crop and variety, approximately 90 to 120 lbs/ac (pure live seed basis) of seed was planted which amounts to 2,000,00 PLS/ac. Each entry was drilled in two adjacent 5- by 10-foot plots, in 7-inch rows, at 1-inch planting depth with a HEGE 500 drill. These adjacent plots were used to represent forage only and dual purpose (forage and grain). Fertilization consisted of preplant incorporation of 80 lbs N/ac on Oct. 3, 2008, at Dupy and on Oct. 6, 2008, at Red River. Soil tests showed all other nutrients to be adequate at both locations. Plots received a topdress application of 80 lbs N/acre on Feb. 5, 2009, at Dupy and on Feb. 6, 2009, at Red River. Annual ryegrass was controlled using Amber application at 0.56 ou/ac on Oct. 2, 2008, at both farms. Plots are harvested with a HEGE sickle bar forage plot harvester at a 3-inch height. Adjacent plots of each variety were harvested at the same time for forage during fall until first hollow stem stage of wheat was reached. At hollow stem stage, the dual purpose half is no longer harvested and was allowed to grow for grain production. At Dupy, forage-only plots were harvested on Jan. 23, March 2, April 22 and June 2, 2009. At Red River, they were harvested on Feb. 10, March 3, May 5 and June 6, 2009. At Dupy, dual purpose plots were harvested on Jan. 23, and at Red River, they were harvested on Feb. 10, 2009. Data was analyzed with the general linear models procedure in SAS (Statistical Analysis Software, Cary, N.C.), and means were separated by the least significant difference (LSD) method (P ≤ 0.05).</p>

	<p>Introduction</p>
<p>Livestock and forage production are the largest contributors to agricultural income in the primary service region of the Noble Foundation. The ryegrass (Lolium multiflorum L) variety testing program is designed to provide up-to-date performance information to cooperators and producers in Oklahoma and Texas about ryegrass varieties that are commercially and commonly available. In addition, the program provides a tool to evaluate and compare experimental breeding lines emerging from the Noble Foundation breeding program as well as other public and private breeding programs. The program is intended to furnish producers with supplemental information, aid decision-making and idea formation.

<p>Materials and Methods</p>
<p>The annual ryegrass variety trial was conducted on a Wilson silt loam soil at the Noble Foundation Headquarters Farm, Ardmore, Okla. The experimental design was a randomized complete block with three replications. The experimental unit was a 5- by 10-foot plot of a single variety. The trial consisted of 28 entries that were evaluated during the 2008-2009 crop growing season. Twelve sources contributed entries to the trial (Table 1). The entries were seeded into a clean-tilled seedbed on Sept. 24, 2008. Each entry was drilled in 5- by 10-foot plots, in 7-inch rows, with 25 lbs/ac (pure live seed) at a ½-inch planting depth with a HEGE 500 drill. Fertilization consisted of preplant incorporation of 120 lbs N/ac and 30 lbs P205/ac, 60 lbs K2O/ ac during September 2008, and a topdress application of 80 lbs N/acre on March 1, 2009.

	<p>Introduction</p>
<p>In an effort to assist cattle producers in Oklahoma and Texas judge forage crop performance, a trial was held to determine forage yield of commercially available varieties and advanced experimental lines of annual ryegrass. The objective of this report is to summarize results from the 2008 trial.</p>
<p>Materials and Methods</p>
<p>The trial was conducted on a Wilson silt loam at the Noble Foundation Headquarters Farm near Ardmore, Okla. The trial consisted of 25 entries contributed from seven sources (Table 1). The entries were seeded in a clean-tilled seedbed on Sept. 17, 2007. Each entry was drilled in 5- by 15-foot plots, in 7-inch rows, at 25 lb/acre (pure live seed basis) at a ½-inch planting depth with a HEGE 500 drill. Fertilization consisted of preplant incorporation of 23 lb P205/acre and 20 lb K2O/acre on Sept. 13, 2007. Plots were topdressed with 80 lb N/acre on Oct. 29, 2007, and Feb. 4, 2008. Plots were harvested with a HEGE sickle bar forage plot harvester at a 3-inch height on Jan. 4, March 14, March 31, April 29 and June 3, 2008. The trial was a randomized complete block design with three replications. Data were analyzed with the general linear models procedure in SAS (Statistical Analysis Software, Cary, N.C.), and means were separated by the least significant difference (LSD) method (P ≤ 0.05).</p>
<p>Results and Discussion</p>
<p>Precipitation was below the 30-year average for Ardmore (Table 2). The deficit occurred primarily during the fall, limiting fall forage production. Good precipitation during the spring allowed for good spring forage production. Consequently, yields on average were 1000 lb/acre greater than average yield of entries in the 2007 trial. by J.A. Guretzky / jaguretzky@noble.org, and S. Norton / slnorton@noble.org Forage yield depended on the harvest date and entry (Table 3). Entries that stood out for producing the most forage during early spring, more than 4000 lb/acre by April 1, included Attain, Big Boss, Diamond T, Ed, Fantastic, Flying A, ME4, ME94, Surrey II, TXR2006-T22 and WD-40. Ed, ME4, ME94 and WD-40 also produced good forage yields during this same time period last year. Entries that stood out for producing more forage during late spring (April 29 harvest) included AM-4T, Attain, Barextra, Big Boss, Florida 4N, Hercules, ISI-LWD4, Jumbo, Marshall, MO 1, Surrey II, Tam TBO, TXR2006-T22 and Verdure (Table 3). When forage yield was examined over the whole season, differences among entries were mostly not significant. Forage yield among the top entries ranged from 6079 to 7420 lb/acre (Table 3). Any entry producing more than 6000 lb/acre across the season performed well.</p>

The objective of this report is to summarize yields from the 2007-2008 trials.</p>
<p>Trial Procedures</p>
<p>The small grains tests were conducted at the Noble Foundation Dupy Farm near Gene Autry and the Red River Demonstration and Research Farm (RRF) near Burneyville, Okla. Soils were a Dale silt loam at Dupy and a Minco fine sandy loam at RRF. Ten sources contributed entries to the trial (Table 1). The entries were seeded in a clean-tilled seedbed on Oct. 4, 2007, at Dupy and Oct. 2, 2007, at RRF. Each variety was sown at 2,000,000 pure live seed (PLS) per acre, which approximated 90 to 120 lb PLS/acre, depending on the crop and entry. Seeds were drilled in 7-inch rows at a 1-inch planting depth with a HEGE 500 drill. The entries were seeded in two adjacent 5- by 15-foot plots. The adjacent plots represented forage only use and dual purpose forage and grain use. Both plots were harvested at the same time for forage during the fall. Once first hollow stem stage of wheat was reached in the spring, the dual-purpose half was no longer harvested for forage to allow grain production. Plots harvested for forage only were harvested on Dec. 4, Feb. 12, March 14, April 1 and May 16 at Dupy and on Dec. 7, Feb. 18, March 18, April 11 and May 19 at RRF. Plots harvested for forage and grain were harvested for forage on Dec. 4 and Feb. 12 and for grain on June 17 at Dupy. At RRF, plots harvested for forage and grain were harvested for forage on Dec. 7 and Feb. 18 and for grain on June 23. Fertilization at Dupy consisted of preplant incorporation of 80 lb N/acre on Sept. 11 and a topdress application of 80 lb N/acre on Feb. 12. At RRF, plots were topdressed with N at 80 lbs/ac on Feb. 18, 2007. An application of Amber at 0.56 ou/acre was applied on Oct. 5 at Dupy and RRF to control annual ryegrass. The trials were randomized complete block designs with three replications. Entries were blocked by crop and randomized within each replication. Data were analyzed by crop with the general linear models procedure in SAS (Statistical Analysis Software, Cary, N.C.), and means were separated by the least significant difference (LSD) method.</p>

	<p>Introduction</p>
<p>In an effort to assist producers in Oklahoma and Texas judge variety performance, the Noble Foundation has held trials to determine forage and grain yields of commercially available varieties and advanced experimental lines of small grains. The objective of this report was to summarize forage yields of commercial varieties in the 2006-2007 trials.</p>
<p>Trial Procedures</p>
<p>The small grains test was conducted at the Noble Foundation Headquarters Farm (HQF) near Ardmore and the Red River Demonstration and Research Farm (RRF) near Burneyville, Okla. Soils were a Heiden clay at HQF and a Minco fine sandy loam at RRF. Twelve sources contributed entries to the trial (Table 1). The entries were planted into a clean-tilled seedbed on Sept. 26, 2006, at HQF and Sept. 19, 2006, at RRF. Each entry was sown at 2,000,000 pure live seed (PLS) per acre, which approximated 90 to 120 lbs PLS/ ac. The seeds were drilled in 7-inch rows at a 1-inch planting depth with a HEGE 500 drill into two adjacent 5- by 15-foot plots. The adjacent plots represented forage only use and dual purpose forage and grain use. Plots harvested for forage were harvested on Feb. 7, March 5 and April 5 at HQF and on Feb. 22, March 20 and April 10 at RRF. Plots harvested for dual purpose forage and grain were harvested for forage on Feb. 7 and for grain on June 6 at HQF, and for forage on Feb. 22 and for grain on June 12 at RRF. At HQF, fertilization consisted of preplant incorporation of 100 lbs N/ac and 46 lbs P2O5/ac on Sept. 19, 2006, and a topdress application of 80 lbs N/ ac on Feb. 16, 2007. Broadleaf weeds were controlled with an application of 2,4-D amine at one pt/ac on Jan. 2, 2007. At RRF, plots were topdressed with 80 lbs N/ac on Nov. 29, 2006, and 70 lbs N/ac on Feb. 23, 2007. Broadleaf weeds did not pose a problem at RRF. The trials were randomized complete block designs with three replications. Variety/strain were blocked by crop and randomized within each replication. Data were analyzed by crop with the general linear models procedure in SAS (Statistical Analysis Software, Cary, N.C.), and means were separated by the least significant difference (LSD) method (P ≤ 0.05).</p>
<p>Results and Discussion</p>
<p>Growing conditions were fair for the trial (Table 2). Although precipitation for Ardmore and Burneyville was near the long-term average from October 2006 through April 2007, forage production was limited by the lack of subsoil moisture following severe drought throughout the spring and summer of 2006. Rainfall increased substantially in May and June, but these increases occurred towards the end of the trial. Fall forage production was best for Bates, Maton II, Wintergrazer 70 and TAMcale 5019 on the clay soils at HQF, as determined by forage yields on Feb. 5 (Table 3). The best fall forage producing wheat varieties on the clay soils included Coker 9553 (soft), Fannin, Kingrazer (soft), Doans and Overley. On sandy loam soils at RRF, the best fall forage producers included the ryes: Bates, Elbon, Maton, Oklon and Wintergrazer 70; the triticales: TAMcale 5019 and TAMcale 6331; and the oats: Dallas, Harrison and Plot Spike (Table 4). Total forage production was similar among all rye and triticale varieties on the clay soils at HQF, ranging from 3188 to 4013 lbs/ac (Table 3). Total annual forage production among wheat varieties was best for Coker 9553 (soft), Doans, Duster, Fannin and Kingrazer (soft), with yields ranging from 3416 to 3968 lbs/ac. Dallas and Harrison had the highest total forage production of oat varieties, ranging from 2775 to 2918 lbs/ac. On the sandy loam sites at RRF, total forage production was best for the ryes: Bates, Maton, Elbon and Oklon; and the triticales, TAMcale 5019 and TAMcale 6331 (Table 4). Total forage production among wheat varieties was best for Custer, Deliver, Doans, Duster, Endurance, Lockett, Overley and Ranger Brand (soft). Overall, varieties that performed well across both locations, in terms of total forage production, included the ryes: Bates, Elbon, Maton and Oklon; the triticales: TAMcale 5019 and TAMcale 6331; and the wheats: Doans and Duster.</p>

	<p>Introduction:</p>
<p>In an effort to assist livestock producers in Oklahoma and Texas judge variety performance, the Noble Foundation has held trials to determine forage yields of commercially available varieties and experimental strains of annual ryegrass. The objective of this report is to summarize forage yields from the 2006-2007 trial.</p>
<p>Materials and Methods</p>
<p>The test was conducted on a Wilson silt loam soil at the Noble Foundation Headquarters Farm near Ardmore, Okla. The trial consisted of 37 entries; 28 were commercially available varieties and nine were experimental strains. Twelve sources contributed entries to the trial (Table 1). The entries were seeded in a clean-tilled seedbed on Sept. 26, 2006. Each entry was drilled in 5- by 15-foot plots, in 7-inch rows, at 25 lbs/ac (pure live seed basis) at a ½-inch planting depth with a HEGE 500 drill. Fertilization consisted of preplant incorporation of 120 lbs N/ac and 23 lbs P<sub>2</sub>0<sub>5</sub>/ac on Sept. 19, 2006, and a topdress application of 80 lbs N/acre on March 1, 2007. Broadleaved weeds were controlled with an application of 2,4-D amine at one pt/ac on Jan. 29, 2007. Plots were harvested with a HEGE sickle bar forage plot harvester at a 3-inch height on Feb. 23, March 26, April 9 and May 14, 2007. The trial was a randomized complete block with three replications. Data were analyzed with the general linear models procedure in SAS (Statistical Analysis Software, Cary, N.C.), and means were separated by the least significant difference (LSD) method (<em>P ≤ 0.05</em>).</p>
<p>Results and Discussion</p>
<p>Growing conditions were good for the trial. After a slow start following severe drought in the spring and summer of 2006, precipitation from October 2006 through April 2007 was near the 106-year average for Ardmore (Table 2). Rainfall increased substantially in May, toward the end of the trial, and exceeded the 106-year annual average by 2.7 inches.</p>

	<![CDATA[
	<p>Recent efforts to derive and study a quasiconserved quantity <em>K</em> in the Henon-Heiles problem in terms of a single set of variables are discussed. Numerical results are given, showing how the value of such a quantity varies with time and order in a power-series expansion for <em>K</em> in terms of monomials of the coordinates and velocities. The lowest order in the power series for <em>K</em> corresponds to <em>n</em> =4 and the highest order to <em>n</em> =27, so that 24 orders are included in the series. The results are compared with an earlier study by the authors [Phys. Rev. A 42, 1931 (1990)] that included an expansion for <em>K</em> for orders <em>n</em> =4 to <em>n</em> =15. In general, even in regions where the earlier study suggested that the series for <em>K</em> might be converging, our more recent results [Phys. Rev. A 44, 925 (1991)], involving twice as many orders, suggest that the series diverges.</p>

	<![CDATA[
	<p>A bilinear integral equation for the cylinder is derived within the meson sector of the theory of dual topological unitarization. The equation is more general than conventional linear cylinder equations since it includes regions of phase space in which produced particles overlap in rapidity. The equation also permits a simple treatment of phase space which corresponds to that of the planar bootstrap problem. Two classes of solutions are found, only one of which results in the Pomero'n-<em>f</em> identity. This treatment also indicates that the residue of the Pomeron may be twice as large as that suggested by earlier calculations but in agreement with a more recent calculation.</p>

	<p>It is shown that the ordinary Born approximation for <em>pn</em> and <em>pp̅</em> charge-exchange scattering correctly accounts for (1) the shape of the forward peak for 0 ≤ <em>(-t</em>) ≤ <em>µ</em><sup>2</sup>/2 at <em>P<sub>L</sub></em> = 8 GeV/<em>c</em>, and (2) the energy dependence of the cross sections at t=0 in the energy range <em>P<sub>L</sub></em>,=2—8 GeV/<em>c</em>. This result is analogous to the well-known success of the electric Born approximation in Π<sup>+</sup> photoproduction. It is then shown that the simplest interpretation of this surprising result within the framework of Regge-pole theory is in terms of the fixed poles which are allowed by unitarity in hadronic amplitudes at certain nonsense points of right signature. Finally, it is shown how such a Axed pole at a nonsense point of one helicity amplitude aGects another amplitude for which the corresponding point is sense.</p>

	<p>It is shown that unitarity allows fixed poles at certain nonsense points of either right or wrong signature. The conditions for the existence of these poles are found. These conditions are then used to locate the poles allowed in hadronic reactions. Possible mechanisms for the poles are considered. It is then argued that fixed poles provide the most natural explanation of the conspiracy phenomenon.</p>

	<![CDATA[
	<p>The problem of finding the coefficients of a simple series expansion for a quasiconserved quantity <em>K</em> for the Henon-Heiles Hamiltonian <em>H</em> using a single set of variables is solved. In the past, this type of approach has been problematic because the solution to the equations determining the coefficients in the expansion is not unique. As a result, the existence of a consistent expression for <em>K</em> to all orders had not previously been established. We show how to deal with this arbitrariness in the expansion coefficients for <em>K</em> in a consistent way. Due to this arbitrariness, we find a class of expansions for <em>K</em>, in contrast to the single unique expansion for <em>K</em> generated by the normal-form approach of Gustavson [Astron. J. 71, 670 (1966)]. It may be possible to devise a criterion for deciding which one of our expansions is "optimally convergent, "although we do not deal with this question here. We proceed by introducing a single set of dynamic variables that have simple symmetry properties and that also "diagonalize" the problem of finding the coefficients of <em>K</em>. No canonical transformations are required. A straightforward constructive procedure is given for generating the power series to any order for quantities having the symmetry of the Hamiltonian that -are formally conserved. This leads to a very practical method for calculating a quasiconserved quantity in the Henon-Heiles problem. A comparison is made through several orders of the terms generated by this approach and those generated in the original Gustavson expansion in normal form.</p>

	<p>We study a power-series expansion for a conserved quantity <em>K</em> in the case of the two-dimensional Henon-Heiles potential. An alternative technique to that of Gustavson [Astron. J. 71, 670 (1966)] is applied to find the coefficients in the expansion for <em>K</em>. The technique is used to determine twelve orders for the conserved quantity <em>K</em>, more than twice as many as that calculated by Gustavson. We investigate the degree of constancy of our truncated <em>K</em> in regions where the motion is known to be chaotic and also where it is nonchaotic.</p>

	<![CDATA[
	<p>A modification of the Omnes method is used to solve the singular integral equations for the 3-3 partialwave amplitudes of photoproduction. The effects of multipion production are assumed to be negligible. The method requires a knowledge of the phase at all energies. Consequently, it is necessary to treat the corresponding pion-nucleon scattering problem to determine the eBect of the high-energy behavior of the phase on the solution for the scattering amplitude at low energies. The sharply resonant nature of the problen suggests an approximation in the form of solution, rather than in the Born terms, which leads to relatively simple expressions for the ratios of the 3-3 photoproduction amplitudes to the scattering amplitude and for integrals involving the 3-3 amplitudes, In addition, a modified Chew-Low formula can be derived which should satisfactorily represent the 3-3 phase shift throughout the resonance regions. Finally, the cross sections are calculated in the 3-3 approximation and the results compared with experiment.</p>

We search for events in which one or more particles are reconstructed as muons but have speed and ionization energy loss (<em>dE/dx</em>) inconsistent with muons produced in beam collisions. CMLLPs are predicted in several theories of physics beyond the standard model. We exclude pair-produced long-lived gauginolike charginos below 267 GeV and Higgsino-like charginos below 217 GeV at 95% C.L., as well as longlived scalar top quarks with mass below 285 GeV.</p>

	<![CDATA[
	<p>A search for a Higgs boson in the four-lepton decay channel <em>H→ZZ</em>, with each <em>Z</em> boson decaying to an electron or muon pair, is reported. The search covers Higgs boson mass hypotheses in the range of 110 < m<sub>H</sub> < 600 GeV. The analysis uses data corresponding to an integrated luminosity of 4.7 fb<sup>-1</sup> recorded by the CMS detector in <em>pp</em> collisions at √<em>s</em> = 7 TeV from the LHC. Seventy- two events are observed with four-lepton invariant mass m<sub>4ℓ</sub> > 100 GeV (with 13 below 160 GeV), while 67.1 ± 6.0 (9.5 ± 1.3) events are expected from background. The four-lepton mass distribution is consistent with the expectation of standard model background production of <em>ZZ</em> pairs. Upper limits at 95% confidence level exclude the standard model Higgs boson in the ranges of 134–158 GeV, 180–305 GeV, and 340–465 GeV. Small excesses of events are observed around masses of 119, 126, and 320 GeV, making the observed limits weaker than expected in the absence of a signal.</p>

	<p>A search for signatures of extra spatial dimensions in the diphoton invariant-mass spectrum has been performed with the CMS detector at the LHC. No excess of events above the standard model expectation is observed using a data sample collected in proton-proton collisions at √<em>s</em> = 7 TeV corresponding to an integrated luminosity of 2.2 fb<sup>-1</sup>. In the context of the large-extra-dimensions model, lower limits are set on the effective Planck scale in the range of 2.3–3.8 TeV at the 95% confidence level. These limits are the most restrictive bounds on virtual-graviton exchange to date. The most restrictive lower limits to date are also set on the mass of the first graviton excitation in the Randall-Sundrum model in the range of 0.86–1.84 TeV, for values of the associated coupling parameter between 0.01 and 0.10.</p>

	<![CDATA[
	<p>A growing body of research has documented associations between discrimination, anger, and delinquency, but the exact nature of these associations remains unclear. Specifically, do aggressive behaviors emerge over time as a consequence of perceived discrimination and anger? Or do adolescents who engage in aggressive behavior perceive that they are being discriminated against and become angry? We use autoregressive cross-lagged path analysis on a sample of 692 Indigenous adolescents (mean age = 12 years) from the Northern Midwest and Canada to answer these research questions. Results showed that the direction of effects went only one way; both perceived discrimination and anger were significantly associated with subsequent aggression. Moreover, early discrimination and anger each had indirect effects on aggressive behavior three years later, and anger partially mediated the association between discrimination and aggression. Perceived discrimination is but one of many strains related to unequal social position that these Indigenous youth experience, and it has important implications for the proliferation of disparities in later life.</p>

Events consistent with the flavorchanging- neutral-current decay of a <em>T</em> quark to a top quark and a <em>Z</em> boson are selected by requiring two leptons from the <em>Z</em>-boson decay, as well as an additional isolated charged lepton. In a data sample corresponding to an integrated luminosity of 1.14 fb<sup>-1</sup>, the number of observed events is found to be consistent with the standard model background prediction.

	<![CDATA[
	<p>Evolving computer technology is offering opportunities for new online approaches in teaching methods and delivery. Well-designed web-based (online) lessons should reinforce the critical need of the soil science discipline in today's food, energy, and environmental issues, as well as meet the needs of the diverse clientele with interest in agricultural and/ or environmental disciplines. The objectives of the project were to: (1) develop web-based lessons in soil genesis and development and (2) evaluate context-based case studies or application lessons (agronomic, environmental, and ecological situations) to teach soil genesis and development. Six principles lessons, along with three applications lessons, were developed for use by undergraduate soil science courses. Pre- and post-tests were used to assess learning gains. A postactivity survey was also used to assess perceptions of the web-based lessons by student users. Students' test performance from pre- to post-test improved by 69%. Although there were no differences in post-test gains among learning styles, or between genders, the students majoring in professional golf management had higher post-test gains than other majors. Since their inception in 2006, lessons have continued to be both primary and supplemental resources for multiple courses serving over 140 students each year at the University of Nebraska-Lincoln and Oregon State University-Cascades. The lessons will be especially useful for teachers who do not have extensive training in soil science yet cover the subject as part of a basic earth science course.</p>

<title>FARMING SYSTEMS RESEARCH/EXTENSION
AND THE CONCEPTS OF SUSTAINABILITY</title>

	<![CDATA[
	<p>Farming Systems Research and Extension (FSR/E) has strongly influenced the direction of agricultural development over the past two decades. Involving farmers, change agents and researchers, this participatory approach to technological improvement has evolved as an efficient means to develop individual components and more integrated systems that are uniquely suited to specific biophysical and socioeconomic conditions. Farmers with similar conditions and for whom specific recommendations are appropriate are grouped, in FSR/E, into identifiable Recommendation Domains. The technologies recommended conform with the biophysical and socioeconomic constraints that create environments within the domains, based on the philosophy that new technologies must conform with the environments where they will be used because most farmers are unable to modify their environments to meet the needs of new technologies. This characteristic differentiates FSR/E from the approach of developing conventional technologies to dominate environments through use of machinery, chemicals, irrigation and other capital-intensive inputs.</p>
<p>The philosophy of sustainable agriculture is gaining ground in a world becoming acutely aware of finite fossil fuel resources and adverse impacts of agriculture and other industries on the environment. In spite of substantial advances in productivity through applications of fertilizers, pesticides, and irrigation, we are learning that inappropriate or excessive use of these inputs can have unexpected and undesirable effects on the environment, natural ecosystems, and the world's human inhabitants. In order to develop the systems that will provide for our needs without endangering the quality of life of future generations, we must concentrate on an efficient use of renewable resources that are available within the immediate production environment. We need to reduce fossil fuel use to minimum essential levels. We must develop technologies that conform more closely with the environments where they will be used. The urgency associated with coming to grips with the problem is becoming more evident every day. These necessities precisely coincide with the capabilities of the FSR/E approach.</p>
<p>FSR/E practitioners work with families who live on the land and are acutely aware of their surrounding environments and how they are influenced by cropping and farming practices and systems. Because farmers participate in the development and testing of alternatives, their evaluation criteria will be used for screening. These may differ from the narrower and often misleading criteria used by researchers trained in specific disciplines. This aspect, in itself, enhances the efficiency and effectiveness of the technology development and adoption process.</p>
<p>When the farmers' concerns and resource base are more explicitly taken into account, technologies thus developed are more readily adapted to the farmers' environments. Perhaps most important, FSR/E on-farm research and technology evaluation methods have proven efficient for screening and selecting technologies that conform to the divergent environments found on farms throughout the world.</p>

	<![CDATA[
	<p>"Food production and rural income are two prime concerns of Third World governments. Increased food production and greater food security are goals which countries strive to achieve through agricultural development. The technologies generated by research, commonly known as green revolution methods, have provided an impetus to food production in some favored zones where resources are available to take advantage of this production package. New varieties, productive and responsive to fertilizer, have bought time while countries work to control population growth and develop agriculture and industry" (Francis and Harwood, 1985).</p>
<p>The pioneering work of the International Agricultural Research Centers has been successful in developing varieties and packages and in training national program scientists and extension specialists to validate and move them to the field. The process and progress have been summarized by Wortman and Cummings (1978). We now know that the substantial inputs of chemical fertilizers, pesticides, and fossil fuels needed to adopt many of these new technologies has made them unavailable or unaffordable to most limited resource farmers. In addition, experience shows that indiscriminate use of fertilizers and pesticides can add unnecessary production costs and even create dangers to farmers and their families.</p>
<p>The greatest immediate challenges facing national research and extension programs and the international centers are the development of appropriate and productive alternative technologies and how to move these practices and systems to those farmers who are as yet beyond the reach of current programs. There is growing concensus about the focus of future research and development priorities, including: <br>--concentration on low-input strategies which depend on internal resources on the farm; <br>--exploitation of biological efficiencies inherent in diversified cropping systems; <br>--development of more productive multiple cropping and crop/livestock integrated systems; <br>--examination of how components fit together in systems and how complex interactions can be understood and used to advantage; <br>--analysis of risk inherent in adoption of new and possibly more expensive technologies; and <br>--application of some farming systems methodology in identification of key constraints and participatory approaches to development of solutions.</p>
<p>These ideas are not new -- many have emerged through experiences of scientists in the international centers and in key national programs. Each of the topics is explored in some detail, with key references given for further reading and study.</p>

	<![CDATA[
	<p>In 1990, a great many POD Network members were saddened by the news that a colleague, friend, and long-time POD member, Robert Pierleoni, (Bob to most of us) had suffered a fatal heart attack. While Bob had served on the CORE Committee two terms, and had been Co-chair of the Delavan, Wisconsin, conference at Lake Lawn Lodge in 1985, and had been a loyal member from early years, the loss of his presence in POD was one felt keenly as a result of something that many of his friends referred to as his "spirit" of being a "POD'er". He was a sharing, caring kind of person who cheerfully volunteered for needed tasks whether there would recognition for his contribution or not. He was the kind of person who personifies the nature of this field of faculty development in a very real way.</p>

	<p>As Bill Jasper left his office and walked down the hall toward his classroom, he found it hard to believe that only a few months earlier he had begun teaching his first class at University College. A wistful smile played at the comers of his mouth as he thought back to that enlightening, but somewhat unsettling, experience. "I was greener than a spring apple," he muttered. "I wish I had known then what I know now."</p>

	<![CDATA[
	<p>This paper describes a successful two-year pilot program on mentoring new junior faculty women. The program emphasizes individual professional development and retention issues and includes colleague-pairing, mentor training, the use of a mentoring agreement, and a multi-leveled series of development workshops, seminars, and networking activities. The assessment and research component includes a needs assessment, pre-and postparticipation perception studies, assessment interviews, and a proposed longitudinal study of mentees from entrance to tenure.</p>

<title>Switchgrass for forage and bioenergy:
Harvest and nitrogen rate effects on biomass
yields and nutrient composition</title>

	<![CDATA[
	<p>Switchgrass (<em>Panicum virgatum</em> L.) may have value as forage and a bioenergy feedstock. Our objective was to evaluate how harvest system and N fertilizer rates affected biomass yield and nutrient composition of young stands of switchgrass (cv. Alamo) in the southern Great Plains, USA. Nitrogen fertilization increased biomass yields from 10.4, 10.8, and 12.2 Mg ha<sup>−1</sup> at 0 kg N ha<sup>−1</sup> to 13.7, 14.6, and 21.0 Mg ha<sup>−1</sup> at 225 kg N ha<sup>−1</sup> when harvested after seed set (October), after frost (December), and twice per year after boot stage (July) and frost, respectively. Nutrient concentrations and removal were generally twice as great when biomass was harvested twice versus once per year. Precipitation strongly affected biomass yields across the two years of these experiments. When late-summer precipitation is available to support regrowth in this environment, harvesting switchgrass twice per year will result in greater biomass yields. Harvesting twice per year, however, will increase fertilization requirements and reduce feedstock biomass quality. Switchgrass harvested during mid-summer after boot stage was of poor forage quality. To have value as a dual-purpose forage and bioenergy feedstock, switchgrass would need to be utilized during spring to early summer while in a vegetative stage.</p>

The six first-year medical students have been struggling to explain the sequence of events experienced by the 17 year old woman in the case who collapses while playing soccer with subsequent ventricular fibrillation and coma. An older female student, Pat, had spoken little during the first 15 minutes of discussion as the group alternately considered the role of brain and heart in the patient's collapse. Finally, Pat quietly commented.</p>

Holmes has taught for many years and has come to the conclusion that the students in his American Government general education course do their best work if he is very precise about his expectations of them. In line with this philosophy, Professor Holmes requires that everyone take the final examination on the day that it is scheduled. The only excuse for missing the examination is an illness that requires a trip to the doctor. Thus, he will give a make-up final exam only if the student brings in a doctor's excuse.</p>

On top of that, it was a required state history course the contents of which most students had in high school. So he was pretty sure students would be coming into the course with bad attitudes right off the bat. But he loved his subject and knew how exciting it could be once you understood the mysteries and problem-solving aspects of history instead of just concentrating on learning facts. He was determined to introduce his students to that aspect of the discipline.</p>

	<![CDATA[
	<p>Because faculty, instructional and organizational development is still a relatively new area, it has undergone dramatic changes not only in the last fifteen years but even in the last two or three years. As the focus on undergraduate education becomes more prevalent, as budgets wax and wane, and as the demographics of the academic population change, it is important that we stay abreast of the latest research, discussion, and information in the field. Thus, it is appropriate that the volume begins with a focus on the context in which we do our work. What is happening in faculty development? What philosophical issues underpin what we do? What are the contextual factors that influence our daily efforts to enhance teaching, learning, and organizational effectiveness on our campuses? Some of these questions are addressed in the articles included in this first section of the volume.</p>

<title>On the spatial heterogeneity of net ecosystem productivity

	<![CDATA[
	<p>Micrometeorological flux towers provide spatially integrated estimates of net ecosystem production (NEP) of carbon over areas ranging from several hectares to several square kilometers, but they do so at the expense of spatially explicit information within the footprint of the tower. This finer-scale information is crucial for understanding how physical and biological factors interact and give rise to towermeasured fluxes in complex landscapes. We present a simple approach for quantifying and evaluating the spatial heterogeneity of cumulative growing season NEP for complex landscapes. Our method is based on spatially distributed information about physical and biological landscape variables and knowledge of functional relationships between constituent fluxes and these variables. We present a case study from a complex landscape in the Rocky Mountains of Montana (US) to demonstrate that the spatial distribution of cumulative growing season NEP is rather large and bears the imprint of the topographic and vegetation variables that characterize this complex landscape. Net carbon sources and net carbon sinks were distributed across the landscape in manner predictable by the intersection of these landscape variables. We simulated year-to-year climate variability and found that some portions of the landscape were consistently either carbon sinks or carbon sources, but other portions transitioned between sink and source. Our findings reveal that this emergent behavior is a unique characteristic of complex landscapes derived from the interaction of topography and vegetation. These findings offer new insight for interpreting spatially integrated carbon fluxes measured over complex landscapes.</p>

	<p>The first class meeting seemed to go smoothly enough. I went in, introduced myself, and ran through the course syllabus and calendar. The students seemed pretty much like the students I taught at State U--maybe a little older. They asked the same questions about how long the papers should be and which books to buy. They made no comments about the journal assignment for the next class. They filled out my survey readily enough. In fact, the class ended twenty minutes early.</p>
<p>In my eight years of teaching at State U, I never saw anything like the survey responses I received from this class. Can community college students be that different? I just don't know how I'm going to cope.</p>

<title>Teachers Engaging Parents as Tutors to Improve Oral Reading Fluency</title>

	<![CDATA[
	<p>This dissertation examined the application of evidence-based tutoring for oral reading fluency (ORF) to a natural setting, using teachers as parent trainers. Measures used to determine the impact of parent tutoring included treatment integrity, student reading outcomes, attitudes towards involvement and reading, and social validity. Six teachers (second through fourth grade) were trained in a 3-hour workshop to develop individualized tutoring programs with parents. Following training, the teachers trained seven parents and students to use individualized tutoring programs. Training followed a behavior skills training model and incorporated video modeling and printed instructions to increase efficiency. A multiple-baseline design was used to evaluate the effect of training on parents’ use of evidence-based reading strategies and of tutoring on students’ ORF. During baseline, parents were asked to practice reading with their child as they typically do. During intervention, parents used the evidence-based tutoring program developed with the teacher. Multiple dimensions of treatment integrity were measured to provide a comprehensive picture of how the tutoring influenced child outcomes, and to inform future practices. The results showed that teachers’ treatment integrity of parent training was high. Six parents showed immediate improvement in their use of evidence-base strategies, but levels of adherence, quality, and dosage varied across parents. Engagement remained high during baseline reading sessions and structured tutoring sessions. Four out of seven of the students showed significant improvements in ORF. Teachers and parents indicated positive beliefs about parent involvement at baseline and post-intervention. Student attitudes towards reading were also generally high and did not show a systematic change from baseline to intervention. Social validity ratings from teachers, parents, and students were favorable, indicating that they perceived the intervention to be acceptable. Results are discussed in terms of the relationship between treatment integrity, student outcomes, and beliefs about involvement. Discussion also focuses on the need for additional research in natural settings to more closely examine the conditions needed for successful implementation of parent tutoring programs and the effect on student outcomes.</p>

	<![CDATA[
	<p>Soybean (<em>Glycine max</em> (L.) Merrill) is a major oilseed commodity which partitions carbon and nitrogen flux during embryogenesis towards two primary storage reserves, protein and oil, at approximately 40% and 20%, respectively in the seed. This attribute makes soybean a valuable feedstock in many food, feed and industrial applications. Over the past decade, a wealth of genomic resources has been established for soybean that will aid in elucidating the underlying biology governing the growth and development of the crop. This in turn will foster innovative breeding and genetics approaches leading to improvements in agronomics and end-use quality. Loss- and gain-of function mutants are powerful resources that complement functional genomics programs. Here we report on the creation of a repository of transgenic soybean events carrying a constitutive activation tag delineated by the maize dissociation (<em>Ds</em>) element, along with transposition frequency estimates of <em>Ds</em> delineated activation tag and enhancer-trap element induced upon stacking with a constitutive maize activator (<em>Ac)</em>-transposase cassette. To meet this goal we produced approximately 587 F<sub>1</sub> <em>Ac</em>-stacks with the <em>Ds</em>-activation tag element and 144 F<sub>1</sub> <em>Ac</em>-stacks with the <em>Ds</em>-enhancer trap element. Among 16 F<sub>2</sub> derived populations from <em>Ac</em> X <em>Ds</em>-activation stacks we observed 26 unique germinal transpositions with an estimated 3.15% transposition frequency. Whereas among 22 F<sub>2</sub> derived populations from the <em>Ac</em> X <em>Ds</em>-enhancer trap stacks only six unique germinal transpositions were detected, translating to an estimated 0.5% transposition frequency. Based on sequence data collected from junctions about the transposed <em>Ds</em> elements it appears that in soybean, <em>Ds</em> quite frequently re-inserts at unlinked positions respective to its corresponding launch site. Two germinal mutants characterized, a <em>Ds</em>-enhancer trap and a <em>Ds</em>-activation tag, landed in the third intron of a putative cyclic nucleotide binding domain gene, and a predicted IMP/GMP specific nucleotidase, wherein the former resulted in a reduction in tagged transcript accumulation, while the latter lead to miss-expression of the tagged gene.</p>

	<p>A study of events with missing transverse energy and an energetic jet is performed using <em>pp</em> collision data at a center-of-mass energy of 7 TeV. The data were collected by the CMS detector at the LHC, and correspond to an integrated luminosity of 36 pb<sup>-1</sup>. An excess of these events over standard model contributions is a signature of new physics such as large extra dimensions and unparticles. The number of observed events is in good agreement with the prediction of the standard model, and significant extension of the current limits on parameters of new physics benchmark models is achieved.</p>

	<![CDATA[
	<p>During oblique vehicular impacts with longitudinal barriers, an occupant’s head is often ejected out of a side window. When this occurs, the occupant’s head can contact the barrier or an object attached thereto. This impact event, often termed head slap, normally produces a serious injury or fatality. Roadside barriers and any attached hardware should be designed with sufficient offset at the top to preclude head slap for most impact conditions. The goal of this study was to identify the extent of head ejection that can be expected during high-speed crashes with longitudinal barriers. High-speed videos of full-scale vehicle crash tests were analyzed to determine the occupant head trajectories. Videos of 11 full-scale crash tests with both small cars and pickup trucks were analyzed to produce a head ejection envelope to encompass all head trajectories observed in the tests. Adjustments were made to the envelope to account for varying vehicle heights, seated passenger heights, and vehicle movements during impact. Two head ejection envelopes were created; one to encompass ejections from occupants at or below the 50th percentile male seated height and the other to encompass ejections from occupants at or below the 95th percentile male seated height. The final head ejection envelopes were constructed as a template for designing future barrier systems and for determining the safe placement of fixed objects on top of or behind rigid parapets.</p>

The data sample corresponds to an integrated luminosity of 34 pb<sup>-1</sup>. The measurement is made for jet transverse momenta in the range 18–1100 GeVand for absolute values of rapidity less than 3. The measured cross section extends to the highest values of jetp<sub>T</sub> ever observed and, within the experimental and theoretical uncertainties, is generally in agreement with next-to-leadingorder perturbative QCD predictions.</p>

	<p>We report results from a search for neutral Higgs bosons produced in association with <em>b</em> quarks using data recorded by the D0 experiment at the Fermilab Tevatron Collider and corresponding to an integrated luminosity of 7.3 fb<sup>-1</sup>. This production mode can be enhanced in several extensions of the standard model (SM) such as in its minimal supersymmetric extension (MSSM) at high tanβ.We search for Higgs bosons decaying to tau pairs with one tau decaying to a muon and neutrinos and the other to hadrons. The data are found to be consistent with SM expectations, and we set upper limits on the cross section times branching ratio in the Higgs boson mass range from 90 to 320 GeV/<em>c<sup>2</sup></em>. We interpret our result in the MSSM parameter space, excluding tanβ values down to 25 for Higgs boson masses below 170 GeV/<em>c<sup>2</sup></em>.</p>

	<![CDATA[
	<p>A search for three-jet hadronic resonance production in <em>pp</em> collisions at a center-of-mass energy of 7 TeV has been conducted by the CMS Collaboration at the LHC, using a data sample corresponding to an integrated luminosity of 35 pb<sup>-1</sup>. Events with high jet multiplicity and a large scalar sum of jet transverse momenta are analyzed using a signature-based approach. The number of expected standard model background events is found to be in good agreement with the observed events. Limits on the cross section times branching ratio are set in a model of gluino pair production with an <em>R</em>-parity-violating decay to three quarks, and the data rule out such particles within the mass range of 200 to 280 GeV/c<sup>2</sup>.</p>

	<![CDATA[
	<p>Electroweak production of the top quark is measured for the first time in <em>pp</em> collisions at <em>√s</em>= 7 TeV, using a data set collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 36 pb<sup>-1</sup>. With an event selection optimized for <em>t</em>-channel production, two complementary analyses are performed. The first one exploits the special angular properties of the signal, together with background estimates from the data. The second approach uses a multivariate analysis technique to probe the compatibility with signal topology expected from electroweak top-quark production. The combined measurement of the cross section is 83.6±29.8 (stat + syst) ± 3.3 (lumi) pb, consistent with the standard model expectation.</p>

	<p>Since the beginnings of faculty development in the early 1960's, professionals in the field have been asked to perform dozens of functions, but one has remained central: helping faculty improve teaching and learning. If there is a single <em>raison d'etre</em> for faculty developers, this is it. Approaching their task with extraordinary energy and dedication, faculty developers have become true pioneers and innovators in the area of teaching-learning. Indeed, they have become some of the most assiduous students of the craft of teaching. And what they learn they generously share. Over the years faculty development professionals have made invaluable contributions to the literature of teaching-learning. The authors contributing to this final Section carry on this honorable tradition.</p>

	<p>Those who till the fields of Academe know that while the basic topography may remain essentially the same over the years, there are always enough changes-in climate, in availability of resources, in supply and demand, in technology-to make the enterprise interesting. Indeed, each decade seems to bring with it a virtual cornucopia of challenges. Certainly the 1980's delivered its fair share of issues and concerns, including that of dealing with the emergence of the adult learner as one of the major forces in higher education.</p>

	<p>Few issues of the past decade have provoked as much interest, print, and passion in Academe as those of gender equality and multicultural diversity. This should come as no surprise. These vital concerns touch the personal and professional lives of all involved in the higher education enterprise: students, faculty, staff, and administrative officers. And if there are to be satisfactory resolutions to the problems we currently face in these areas, each of us must do his or her utmost, including, of course, the faculty development professional. The four articles in this section boldly, but judiciously, address the issues of gender and multiculturalism, not only providing valuable insights into the problems we face, but also suggesting practical strategies for helping achieve the kind of equality of opportunity for which we strive.</p>

	<p>Faculty development is a sophisticated, dynamic, demanding, and challenging field that calls for professional staff possessing a broad range of competencies, skills, and positive personal qualities. Indeed, as Sell and Chism point out in an earlier article, the "range of competencies and attributes needed for a faculty developer suggests a person who can 'walk on water' -- one who has a rare blend of conceptual, technical, interpersonal, and organizational skills." But even those developers fortunate enough to possess such enviable skills and attributes need something else if they are to flourish as facilitators. The formula for success calls for still another essential ingredient-the help and counsel of professional colleagues. Sharing is not only the hallmark of our enterprise, but also the secret of our survival. The first chapter in the success stories of most faculty development professionals follows a predictable scenario. Those familiar with the field have probably heard it dozens of times: At first I didn't know which way to turn, but I gained a sense of direction after picking up the phone and talking to a few of the "veterans."</p>

The jet energy calibration and the method used to extract the inclusive jet cross section are described.We discuss the main uncertainties, which are dominated by the jet energy scale uncertainty. The results cover jet transverse momenta from 50 GeV to 600 GeV with jet rapidities in the range -2.4 to 2.4 and are compared to predictions using recent proton parton distribution functions. Studies of correlations between systematic uncertainties in transverse momentum and rapidity are presented.</p>

	<p>If the faculty development enterprise is to maintain its health and vigor through this decade and into the next century, its practitioners and caretakers must not only address present needs, but also prepare for the future-in part by studying the past. Tunnel vision and near-sightedness spell doom to a field whose success depends so heavily upon its ability to quickly and effectively meet the changing needs of the professoriate. Thus, as faculty development professionals we are called upon not only to serve as counselors and facilitators, but also as historians and visionaries. We must study our brief, but rich, history to avoid making the mistakes of the past, and we must wisely extrapolate from present conditions to successfully meet the challenges of the future.</p>

<title>Impact of Computerized “Sounding out” on Spelling
Performance of a Child Who Uses AAC: A Preliminary Report</title>

	<![CDATA[
	<p>Spelling is a vital skill for people who rely on augmentative and alternative communication (AAC). The ability to spell words provides an opportunity to create novel and spontaneous communication and increases educational, social, and employment opportunities for children and adults. However, many children and youth who rely on AAC struggle to gain functional spelling skills and written language. The purpose of this preliminary investigation was to develop a strategy to provide auditory letter-sounds using commercially available computer equipment and to evaluate how such a computerized “sounding out” strategy influences spelling accuracy for one child who required AAC support. The spelling accuracy of both consonants and vowels increased during intervention sessions when individual sounds associated with target words were provided compared to the baseline session when individual sounds were not provided. Future directions are discussed.</p>

	<![CDATA[
	<p>A search is performed for heavy particle pairs produced in <em>√s</em>= 7 TeV proton-proton collisions with 35 pb<sup>-1</sup> of data collected by the CMS experiment at the LHC. The search is sensitive to squarks and gluinos of generic supersymmetry models, provided they are kinematically accessible, with minimal assumptions on properties of the lightest superpartner particle. The kinematic consistency of the selected events is tested against the hypothesis of heavy particle pair production using the dimensionless <em>razor</em> variable <em>R</em>, related to the missing transverse energy <em>E</em><sup>miss</sup> <sub>T</sub> . The new physics signal is characterized by a broad peak in the distribution of <em>M<sub>R</sub></em>, an event-by-event indicator of the heavy particle mass scale. This new approach is complementary to <em>E</em><sup>miss</sup> <sub>T</sub> -based searches. After background modeling based on data, and background rejection based on <em>R</em> and <em>M<sub>R</sub></em>, no significant excess of events is found beyond the standard model expectations. The results are interpreted in the context of the constrained minimal supersymmetric standard model as well as two simplified supersymmetry models.</p>

	<![CDATA[
	<p>Purpose: The purpose of this investigation was to describe age- and consistency-related changes in the temporal characteristics of chewing in typically developing children between the ages of 4 and 35 months and adults using high-resolution optically based motion capture technology.</p>
<p>Method: Data were collected from 60 participants (48 children, 12 adults) across 5 age ranges (beginners, 7 months, 12 months, 35 months, and adults); each age group included 12 participants. Three different food consistencies were trialed as appropriate. The data were analyzed to assess changes in chewing rate, chewing sequence duration, and estimated number of chewing cycles.</p>
<p>Results: The results revealed both age- and consistency-related changes in chewing rate, sequence duration, and estimated number of chewing cycles, with consistency differences affecting masticatory timing in children as young as 7 months of age. Chewing rate varied as a function of age and consistency, and chewing sequence duration was shorter for adults than for children regardless of consistency type. In addition, the results from the estimated number of chewing cycles measure suggest that chewing effectiveness increased with age; this measure was also dependent on consistency type.</p>
<p>Conclusions: The findings suggest that the different temporal chewing variables follow distinct developmental trajectories and are consistency dependent in children as young as 7 months of age. Clinical implications are detailed.</p>

	<p>Purpose: The goal of this study was to determine if talkers with ALS are limited in their ability to increase lower lip and jaw speed at an early stage of the disease when their speaking rate and intelligibility are only minimally or not affected.</p>
<p>Method: A novel metronome paced fixed-target task was used to assess movement speed capacities during lower lip and jaw oscillations in seven talkers with ALS and seven age and gender matched controls.</p>
<p>Results: Lower lip peak speeds were significantly lower in talkers with mild ALS than in healthy talkers suggesting a lower lip speed constraint in talkers with mild ALS. Jaw peak speeds tended to be lower, but jaw displacements tended to be larger in talkers with mild ALS than in healthy talkers. Because greater speeds are typically expected for larger displacements, outcomes also suggest a jaw speed constraint in talkers with mild ALS.</p>
<p>Conclusions: Lower lip and jaw peak speeds may be sensitive measures to identify bulbar motor performance decline at an early stage of the disease when speaking rate and intelligibility are only minimally affected.</p>
<p>Learning Outcomes: The reader will be able to explain two different articulatory strategies to increase speaking rate and understand why fast speech tasks and diadochokinetic pseudo-speech tasks are not suited to assess articulatory speed capacity in healthy and impaired talkers. The reader will also be able to explain how orofacial movement speed capacity can be tested using a fixed-target task and how ALS affects lower lip and jaw speed capacities during the early stages of the disease.</p>

	<![CDATA[
	<p>We present a measurement of forward-backward asymmetry in top quark-antiquark production in proton-antiproton collisions in the final state containing a lepton and at least four jets. Using a data set corresponding to an integrated luminosity of 5.4 fb<sup>-1</sup>, collected by the D0 experiment at the Fermilab Tevatron Collider, we measure the <em>tt̅</em> forward-backward asymmetry to be (9.2 ± 3.7)% at the reconstruction level. When corrected for detector acceptance and resolution, the asymmetry is found to be (19.6 ± 6.5)%. We also measure a corrected asymmetry based on the lepton from a top quark decay, found to be (15.2± 4.0)%. The results are compared to predictions based on the next-to-leading-order QCD generator MC@NLO. The sensitivity of the measured and predicted asymmetries to the modeling of gluon radiation is discussed.</p>

The search is based on data collected by the D0 experiment at the Fermilab Tevatron Collider at √<em>s </em>= 1.96 TeV corresponding to 5.3 fb<sup>-1</sup> of integrated luminosity. We require two isolated leptons (electrons or muons) with the same electric charge and additional kinematic requirements. No significant excess above background is observed, and we set 95% C.L. observed (expected) upper limits on ratio of the production cross section to the standard model prediction of 6.4 (7.3) for a Higgs boson mass of 165 GeV and 13.5 (19.8) for a mass of 115 GeV.</p>

<description>
	<![CDATA[
	<p>The objective of this study was to characterize the effect of hybrid and environment on physical and chemical characteristics of popcorn kernels that have shown importance in predicting end-use quality. Three popcorn hybrids grown in three different environments were tested for physiochemical attributes and popping performance. Hybrid had a significant effect on kernel sphericity, time-to-grind, dietary fiber, sugars, and starch. Environment effect alone affected total mineral content. Hybrid and environment main effects influenced test weight, tangential abrasive dehulling device index, thousand-kernel weight, total carbohydrates, and kernel protein content. Oil adherence to the bag averaged 15.8% and was proportional to oil amount added prior to microwave popping. Unpopped kernels averaged 11.4 ± 5.3%. Most unpopped kernels were observed to successfully pop when heated a second time in microwave tests. Expansion volume was 44.7 ± 3.7 and 47.3 ± 6.4 cm3/g, depending on the method of determination. Expansion volume was correlated (p < 0.05) with several kernel physiochemical parameters that were influenced by hybrid effect. Sphericity, thousand-weight, and total fat are physiochemical characteristics that appear to be good predictors (p < 0.05) of expansion volume.</p>

<title>Effect of Nitrogen Fertilizer Rate and Harvest Season on Forage Yield, Quality, and Macronutrient Concentrations in Midland Bermuda grass</title>

	<![CDATA[
	<p>Bermuda grass [<em>Cynodon dactylon</em> (L.) Pers.] is a major forage for grazing and hay production in the southern United States. The objectives of this study were to determine effects of nitrogen (N) fertilization rate (0, 112, 224, 336, and 448 kg ha<sup>−1</sup>), split spring and summer applications of N at the 224 and 448 kg ha<sup>−1</sup> rates, and harvest periods (spring and summer) on forage yield, crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDN), and concentrations of phosphorus (P), potassium (K), magnesium (Mg), and calcium (Ca) in Midland Bermuda grass. Data were collected from 2002 to 2008 as part of an ongoing, long-term soil fertility experiment in southern Oklahoma. Repeated measures analysis of these long-term data showed that forage yield responses to N rate varied with year and harvest time with up to 2.5-fold yield differences among years. Nitrogen fertilization increased CP, TDN, and macronutrient P and Mg and decreased ADF and NDF. Crude protein was increased by ≥50%, and ADF and NDF dropped by up to 25% with the greatest N rate. In general, split N applications did not affect forage yield but produced low-quality forage compared to single N application in spring. Split application of 448 kg N ha<sup>−1</sup> gave forage with CP, TDN, ADF, and NDF similar to the Bermuda grass receiving 336 or 448 kg N ha<sup>−1</sup> as a single application. Spring forage had better forage quality than summer harvests. While N fertilization increased forage Mg and P concentrations by more than 50% during both spring and summer, it had no effect or slight increased K and Ca concentrations. In the southern Great Plains, despite the weather-dependent variability in forage yield of Bermuda grass, N application increase forage quality.</p>

<description>
	<![CDATA[
	<p>We present an extension of the Rishon Model of Harari, et. al. [1] [2] [3] In that model, the first generation leptons and quarks are each made from three rishons of two varieties, T and V as follows: <em>v</em><sub>e</sub> = V V V , e<sup>+</sup> = T T T , <em>d</em> = T V V , and <em>u</em> = T T V . In addition to the original rishons and their anti-rishons T and V , we introduce the dark rishon X and its anti-rishon X; all have spin 1/2.</p>
<p>An exciting possibility that emerges from this idea is the possiblity of ‘beams’ of dark matter coming from the decays of higher generation fermions – much in the same way as ‘beams’ of neutrinos are made. The result of such collisions could produce known particles via color/hypercolor interactions or another - as yet unknown - interaction of dark rishons.</p>

We obtain A<sup>b</sup><sub>sl</sub> = (-0.787 ± 0.172 (stat) ± 0.093 (syst)) %. This result differs by 3.9 standard deviations from the prediction of the standard model and provides evidence for anomalously large <em>CP</em> violation in semileptonic neutral <em>B</em> decay. The dependence of the asymmetry on the muon impact parameter is consistent with the hypothesis that it originates from semileptonic <em>b</em>-hadron decays.</p>

	<![CDATA[
	<p>Diaryliodonium salts are shown to undergo rapid, fluoride-promoted aryl exchange reactions at room temperature in acetonitrile. Aryl exchange is shown to be exquisitely sensitive to the concentration of fluoride ion in solution; fast exchange is observed as the fluoride concentration approaches a stoichiometric amount at 50 mM substrate concentration. The reaction is slowed, but not halted if benzene is the solvent, indicating that free fluoride ion or a four-coordinate anionic I(III) species may be responsible for the exchange. The fluoride-promoted aryl exchange reaction is general and allows direct measurement of the relative stabilities of diaryliodonium salts featuring different aryl substituents. The aryl exchange reaction may be of practical use for the preparation of hitherto inaccessible diaryliodonium salts, thus it also has implications for labeling radiotracers for molecular imaging with <sup>18</sup>F-fluoride (t<sub>1/2</sub> = 109.7 min).</p>

	<![CDATA[
	<p>We present a direct measurement of the mass difference between top and antitop quarks (∆m) in lepton + jets tt final states using the ‘‘matrix element’’ method. The purity of the lepton + jets sample is enhanced for tt events by identifying at least one of the jets as originating from a b quark. The analyzed data correspond to 3.6 fb-1 of pp collisions at √s = 1.96 TeV acquired by D0 in Run II of the Fermilab Tevatron Collider. The combination of the e + jets and µ + jets channels yields ∆m =0.8 ± 1,8 stat ± 0.5(syst) GeV, which is in agreement with the standard model expectation of no mass difference.</p>

<title>A predictive model for detection of Agrilus planipennis (Col.,

	<![CDATA[
	<p><em>Agrilus planipennis </em>(emerald ash borer, Coleoptera: Buprestidae) is a pest of ash (<em>Fraxinus</em> spp.) in North America and has caused mortality of ash throughout its introduced range. One technique used for detection of <em>A. planipennis </em>is the establishment and peeling of girdled trap trees. In an effort to reduce the search effort and target detection survey efforts within ash trap trees, a predictive model was created using data from 2007 and validated using data from 2008. In 2007 and 2008, ash trap trees were established, harvested, peeled and inspected for <em>A. planipennis </em>larvae. Gaussian curves were fit to describe the relationship between stem diameter and relative proportion and frequency of larvae. The observed and predicted 2008 relative proportion and frequency of larvae did not differ in paired t-tests. Within the relative proportion and frequency Gaussian models, the curves peaked at approximately 10 cm iameter signifying the greatest proportion and frequency of <em>A.</em> <em>planipennis </em>larvae occurred at 10 cm stem diameter. This peak was then bracketed by 2 cm on each side creating a target stem section with a top diameter of 8 cm and a bottom diameter of 12 cm. A simple linear regression was fit to describe the relationship between the larvae count within the targeted 8–12 cm section of tree and the larvae per cm<sup>3 </sup>of phloem per tree for 2007. The observed and predicted 2008 larvae per cm<sup>3 </sup>did not differ in a paired t-test. Targeting the 8–12 cm diameter section of the trap tree stem will reduce the amount of the tree peeled to less than 45% with more than 50% of <em>A. planipennis </em>larvae within the tree encountered in this targeted section. This reduction in the amount of tree peeled will greatly increase the number of trees and area surveyed for <em>A. planipennis </em>detection and population delimiting surveys.</p>

	<![CDATA[
	<p>A cryoelectron microscopy 8.5 Å resolution map of the 1,900 Å diameter, icosahedral, internally enveloped <em>Paramecium bursaria</em> chlorella virus was used to interpret structures of the virus at initial stages of cell infection. A fivefold averaged map demonstrated that two minor capsid proteins involved in stabilizing the capsid are missing in the vicinity of the unique vertex. Reconstruction of the virus in the presence of host chlorella cell walls established that the spike at the unique vertex initiates binding to the cell wall, which results in the enveloped nucleocapsid moving closer to the cell. This process is concurrent with the release of the internal viral membrane that was linked to the capsid by many copies of a viral membrane protein in the mature infectous virus. Simultaneously, part of the trisymmetrons around the unique vertex disassemble, probably in part because two minor capsid proteins are absent, causing Paramecium bursaria chlorella virus and the cellular contents to merge, possibly as a result of enzyme(s) within the spike assembly. This may be one of only a few recordings of successive stages of a virus while infecting a eukaryotic host in pseudoatomic detail in three dimensions.</p>

	<![CDATA[
	<p>Maize (<em>Zea mays </em>L.) is an important crop in Brazil, and concerns  about grain quality are increasingly important with increasing exports  and use of grain for specific end-uses. A wide range of genotypes are  grown and N application is required to produce high yields. The  objectives of these studies were to: (i) determine N application effects  on the kernel hardness and breakage susceptibility of a wide range  of Brazilian genotypes ranging from dent to flint kernel types and  (ii) determine relationships among kernel hardness and breakage  susceptibility tests, yield and N and oil concentration. Three studies were conducted with a broad range of maize genotypes and N application rates of 0, 60, 120, and 180 kg ha<sup>–1</sup>. Grain was harvested and  yields corrected for water content, and grain was evaluated through  a series of chemical and physical quality tests. Application of 180 kg  ha<sup>–1</sup> N application increased grain yield by 747 to 1466 kg ha<sup>–1</sup>,  increased grain N concentration by 0.9 to 2.4 g kg<sup>–1</sup>, and increased  hardness to a lesser extent, while reducing breakage susceptibility by  1.9 to 6.9%. Genotype had a much larger influence on grain quality  parameters than did N rate. The limited correlation between grain  yield, grain N concentration, and grain oil concentration to kernel hardness suggests that development of further improved genotypes  with high maize yields and excellent drymilling grain quality is feasible  in Brazil. The large variation in grain yield and dry milling grain  quality in intermediate kernel-type (semident, semiflint) genotypes  used in Brazil presents short-term potential to select hybrids that  produce both high yield and good dry milling grain quality.</p>

	<p>Soybean [<em>Glycine max </em>(L.) Merr.] rotation enhances grain sorghum [<em>Sorghum bicolor </em>(L.) Moench] yield, but infl uence on grain quality has not been measured. The objective was to determine the effect of cropping sequence (CS) and soil amendment (SA) on grain yield and quality. Sorghum grain yield and quality, soil NO<sub>3</sub>–N and water were measured in a rotation study in 2003 and 2004 on a Sharpsburg silty clay loam (fine, smectitic, mesic Typic Argiudoll). Cropping sequences were continuous sorghum, and sorghum rotated with non-nodulating and nodulating soybean. Soil amendments consisted of no amendment, manure (17–26 Mg dry matter ha<sup>−1</sup> yr<sup>−1</sup>), and N (84 kg ha<sup>−1</sup> yr<sup>−1</sup>). CS × SA interaction effects were found for most parameters. Rotation with non-nodulating soybean without SA increased yield by 2.6 to 2.8 Mg ha<sup>−1 </sup>over continuous sorghum without SA. Rotation without SA with nodulating soybean further increased yield by 1.7 to 1.8 Mg ha<sup>−1</sup> over rotation with non-nodulating soybean. Grain N increased by 0.5 to 1.0, 2.5 to 5.0, and 3.3 to 4.9 g kg<sup>−1</sup> for N application to continuous sorghum and sorghum rotated with non-nodulating and nodulating soybean, respectively. Tangential abrasive dehulling device (TADD) removal indicated that continuous sorghum without SA produced the softest grain with 43 to 44% TADD removal, and sorghum rotated with nodulating soybean with manure produced the hardest grain with 22 to 27% TADD removal. As food end-use opportunities for sorghum grain evolve, use of crop rotation and SA application will be important to produce grain with desirable quality attributes.</p>

	<p>Grain processors would benefi t from information about the production environment and the infl uences of the sorghum [Sorghum bicolor (L.) Moench] hybrid on food-grade fl our properties. The objective of this study was to determine the effects of environment and hybrid on rapid-visco-analysis (RVA) fl our properties of commercially available food-grade sorghum. A randomized complete block experiment was planted in 12 environments, which included the 2004 and 2005 growing seasons and irrigated and dryland water regimes in eastern, central, and west central Nebraska, and a dryland, low-N environment in eastern Nebraska. The environment accounted for 71–85% of the total variation in RVA parameters, while the hybrid accounted for 11–23% and the environmentby- hybrid interaction, 1–3%. Unfortunately, the results of this experiment suggest that it is diffi cult to predict the effect that environment will have on resulting sorghum-fl our parameters. Although of secondary importance in terms of total variation in sorghum-fl our RVA properties, the choice of hybrid predictably and signifi - cantly contributes to sorghum-starch viscosity properties. Food-grade hybrids were grouped based on viscosity properties into those best suited for dry-mill and alkaline-cooked products (Asgrow Orbit; Sorghum Partners NK1486) and those best suited for porridge, consumable alcohol, and ethanol production (Kelly Green Seeds KG6902; NC+ Hybrids 7W92; Asgrow Eclipse; and Fontanelle W-1000). These results were consistent with those previously reported for grain density.</p>

	<p>Few studies have examined grain quality of food-grade sorghum hybrids. The objective of this study was to determine the effects of environment and hybrid on grain quality of commercially available food-grade sorghums. A randomized complete block experiment with three replications was planted in 12 environments, which included the 2004 and 2005 growing seasons and irrigated and dryland water regimes in eastern, central, and west central Nebraska and a dryland low-N environment in eastern Nebraska. Environment accounted for 5 to 140 times greater variation in measured parameters than hybrid, and the hybrid × environment interaction accounted for less than 2% of the total variation. Grain yield and kernel mass varied, with low yields of 1.4 Mg ha<sup>−1</sup> and kernels weighing 9.5 g 1000 kernels<sup>−1</sup> in the low-N 2004 environment, high grain yields of 10.5 Mg ha<sup>−1</sup> under irrigated conditions in central Nebraska in 2005, and kernels weighing 27.8 g 1000 kernels<sup>−1</sup> in the eastern Nebraska dryland 2005 environment. Harder grain was produced in 2005 than in 2004, with the west central and central 2005 environments having the lowest tangential abrasive dehulling device (TADD) removals of 14%. Non-food-grade hybrids produced higher grain yields and kernel mass than food-grade hybrids. Grain hardness was greater for nonfood- grade and medium maturity hybrids when environmental means were lower (i.e., softer) but showed little or no difference in hardness when environmental means were high. Nebraska production environments have the capability to produce high quality food-grade sorghums for specific food uses to benefit both the producer and the food processor.</p>

	<p>Stockpiled bermudagrass [<em>Cynodon dactylon </em>(L.) Pers. ‘Midland’] as a standing forage may meet nutritional needs of beef cows during winter. Our objective was to evaluate accumulation and nutritive value of fall stockpiled bermudagrass in response to N fertilization rate, N application date, and harvest date. Research was conducted near Burneyville, OK from 2000 to 2003. Fertilization rates included 0, 50, 100, and 150 lb N per acre applied on 15 August, 1 September, 15 September, 1 October, and 15 October. Forage accumulation was measured 10 days after the first killing frost; thereafter, crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), and total digestible nutrients (TDN) were assessed biweekly from 6 December to 20 February. An exceptionally hot and dry summer resulted in negligible forage production and unrepresentative forage quality in 2000. Forage accumulated linearly in 2001 and 2002 and quadratically in 2003 with N fertilization rate (<em>P </em>≤ 0.05). The dry matter averaged 56% TDN and 6.0, 6.9, 7.9, and 8.7% CP when N was applied at 0, 50, 100, and 150 lb/acre, respectively. The fertilized bermudagrass stands would have met CP and TDN requirements of mid-gestation beef cows had they been maintained on this forage.</p>

<title>HIGH-RESOLUTION CORRELATION OF THE UPPER CRETACEOUS STRATIGRAPHY BETWEEN THE BOOK CLIFFS AND WESTERN HENRY MOUNTAINS SYNCLINE, UTAH, U.S.A.</title>

	<![CDATA[
	<p>This study presents high-resolution correlations of the Upper Cretaceous stratigraphy between the Book Cliffs and the western Henry Mountains Syncline in Utah. The objective of this study is to understand changes in patterns of regional sediment dispersal during the Late Cretaceous on the western margin of the Cretaceous Western Interior Seaway. The intensely studied Book Cliffs consist of formations deposited in terrestrial, marginal-marine, and open-marine environments. A composite section was logged at Coal Canyon near Green River, UT. The western Henry Mountains Syncline is located in south-central Utah ~135 km S-SW of Coal Canyon. A composite section was logged at Blind Trail. High-resolution correlation between the Book Cliffs and Henry Mountains is not straightforward because the correlative interval in the Henry Mountains succession is highly condensed (~1015m) relative to the Book Cliffs succession (>1750m). This is in part due to their proximal vs. distal locations from the Sevier thrust front and unequal rates of accommodation creation caused by spatially variable subsidence and uplift patterns. Correlating at high-resolution from Coal Canyon to the Henry Mountains section poses similar challenges as correlating from the eastern Book Cliffs to the Wasatch Plateau because key stratigraphic surfaces in shallow-marine successions cannot necessarily be carried into coeval coastal plain strata up-depositional dip. Radiogenic isotope ages and biostratigraphic data provide age constraints on correlations between the Coal Canyon and Blind Trail sections. Correlations are based on vertical facies and depositional environmental stacking patterns, and changes in sediment dispersal directions at discrete stratigraphic horizons derived from 745 paleocurrent measurements. Recognition of these patterns suggest that the Muley Canyon Sst., Muley Canyon Coal Zone at the base of the Masuk Fm., and the Masuk Fm. correlate to the Star Point Fm., basal Blackhawk transgressive coal zones, and the Blackhawk Fm., respectively, in the Wasatch Plateau. These interpretations provide the means to then correlate the Henry Mountains and Book Cliffs sections as well as allowing pinning points that constrain correlations both up- and down-stratigraphic section.</p>
