Soil Quality Assessment After Weed-Control Tillage In A No-Till Wheat–Fallow Cropping System, T. A. Kettler, Drew J. Lyon, John W. Doran, W. L. Powers, Walter W. Stroup

Panhandle Research and Extension Center

Adoption of reduced-tillage fallow systems in the western USA is limited by winter annual grass weeds such as downy brome (Bromus tectorum L.). Moldboard plowing is an effective means of controlling downy brome in winter wheat (Tritcum aestivum L.)–fallow systems. The purpose of this study was to assess the influence of plowing and secondary tillage operations, for the purpose of weed control, on soil quality attributes of a silt loam soil that had been cropped in a subtill or no-till (NT) winter wheat–fallow system for more than 20 yr. Compared with undisturbed NT, downy brome populations in plowed …

1. A Process-Oriented Model Of Metacognition: Links Between Motivation And Executive Functioning, John G. Borkowski, Lorna K. S. Chan, Nithi Muthukrishna

Issues in the Measurement of Metacognition

The measurement of metacognition has gone through four overlapping phases: The first phase began with the insightful and stimulating paper of Kreutzer, Leonard, and Flavell (1975) on introspective reports about memory states and processes, followed by an important theoretical chapter on the nature of metamemory (Flavell & Wellman,1977). These early contributions documented, and theoretically clarified, the fact that children could accurately report their knowledge about memory events as they related to a variety of tasks, circumstances, and strategies; furthermore, memory knowledge was shown to be age-related. A second phase quickly followed: The intention here was to show interconnections between memory …

A Sense Of Place And Identity In Aotearoa New Zealand, Kelly Thompson

Textile Society of America: Symposium Proceedings

This presentation focuses on a few contemporary artists who use textiles to express connections with place and sense of self, in the "Land of the Long White Cloud", Aotearoa New Zealand. It is a subjective selection, representing both established practitioners and emergent voices, people who are approaching concepts in textile media from varying viewpoints and sources, including cultural, geographical and material relationships.

Being an island nation, in the southern part of the South Pacific, this is a land in which various waves of migration have occurred, beginning with the original settlers, the Maori. According to current archaeological evidence the first …

Approaching Fabrics Through Impressions On Pottery, Penelope B. Drooker

Textile Society of America: Symposium Proceedings

Organic fabrics only rarely survive under archaeological conditions. Particularly in humid temperate or tropical zones, textiles and other fiber perishables rapidly decompose and disappear quite soon after deposition. A few remnants may be found in dry caves or anerobic wet sites, or as charred fragments or metal pseudomorphs, but these represent only a tiny proportion of regional prehistoric fabric production. Fortunately, though, the archaeological record does sometimes yield secondary evidence in the form of impressions on pottery of yam, fabric, and basketry.

Following the theme of this year's TSA symposium, "Approaching Textiles, Varying Viewpoints," this paper focuses on methods and …

Bureaucratic Ideals And Artisanal Reality Survival Strategies In The Production Of Echigo J U, Melissa M. Rinne

Textile Society of America: Symposium Proceedings

The production of Echigo j u, a fine Japanese ramie textile, is in crisis. Woven on a body-tension 100m from hand-plied threads and often incorporating detailed warp and weft kasuri (ikat), Echigo j u is arguably one of the most sophisticated extant bastfiber traditions in Japan, and perhaps the world. Media and researchers alike regularly laud its ancient production processes, but contemporary makers are facing the almost insurmountable challenge of remaining financially solvent in a rapidly diminishing kimono market, with an increasing scarcity of artisans. One reason that Echigo j u survives today is because it has …

From Paint To Wool: Artist-Weavers At The Victorian Tapestry Workshop, Tina Kane

Textile Society of America: Symposium Proceedings

This paper considers the relation between painting and contemporary tapestry. I will be asking the question: does the translation of a painting into a tapestry accomplish something more, categorically, than would the painting on its own? As we will see, this question suggests another, larger one: did tapestry emerge in the twentieth century as an authentic, original artform in its own right?

For years tapestry was considered a mere decorative accessory to painting, in part, because the artist, the designer, did not participate directly in its actual production. In an attempt to redress this prejudice, a model of collaboration between …

Material And The Promise Of The Immaterial, Ingrid Bachmann

Textile Society of America: Symposium Proceedings

The rhetoric around digital technologies is infused with the utopian promises of deliverance and progress - the promise of another frontier, an original uncharted space, virgin territory, a clean slate, another chance to "get it right". This notion of the frontier has almost mythic proportions in the language and literature of the West. From the 'promised land' offered in the Bible, to the lost Garden of Eden, from Columbus' arrival in the Americas, to the cowboy and Indian films of the 1950's and the space adventure films of the 1980's and 1990's, the notion of the frontier continues to engage …

Museum Viewpoint: Fiber Art And The Struggle For Recognition, Melissa Leventon, Lotus Stack, Suzanne Baizerman

Textile Society of America: Symposium Proceedings

Museums are important repositories of culture and play a key role in shaping values concerning art. Indeed, museum acceptance can validate the worth of an artwork, and is often a prerequisite for an artist's long-term success. Contemporary fiber, like textiles in general, occupies a lowly position within the hierarchy of large museums, where it constantly struggles for the position and recognition that other media are automatically granted. Smaller museums and those not focused solely on art can be more accepting, but they, too, discriminate against textiles. In order to challenge this status quo, it is essential to understand how museums …

Performative Textile Gestures, Ann Newdigate

Textile Society of America: Symposium Proceedings

I wrote that in 1996, when a photograph that I had abandoned 30 years before came back to claim me. The image, of myself and three other young white women on camels in front of the Egyptian pyramids, acquires timelessness because all cars in the large parking lot are artfully invisible. I also wrote that "in the year 2000 I will have been here longer than there". I speak from a constituency that has no continuity with tradition, and which is removed from ancestors. It was the moment when I began to seek a visible format for the complexities …

Perpetuating Ritual Textile Traditions: A Pueblo Example, Laurie D. Webster

Textile Society of America: Symposium Proceedings

For over a thousand years, textiles have played a vital role in Pueblo ritual and social identity, linking past and present and reinforcing cultural bonds between widespread Pueblo communities. The group known collectively as the Pueblo Indians of the southwestern United States includes the Hopi people of northern Arizona, the Acoma, Laguna, and Zuni people of western New Mexico, and a string of Pueblo communities located near the Rio Grande in the vicinity of modem-day Albuquerque, Santa Fe, and Taos. Contemporary Pueblo people use virtually the same styles of ceremonial garments as those worn by their ancestors five to six …

Reinventing A Cultural Self: Textile Design And Native American Youth, Wendy Weiss, Mary Lee Johns

Textile Society of America: Symposium Proceedings

This presentation shows how the University Textiles, Clothing and Design department and the Indian Center of Lincoln, Inc., are collaborating to provide creative textile design programs for a group of 12 at-risk Native American youth, 12-18 years old. Family therapist, Dr. Gloria Gonzalez-Kruger, is conducting a research component which assesses the project's impact on youth development, cultural identity development, and intercultural relationships. The data will provide information on how to develop and implement culturally competent programs for youth.

Fall 1998, the youth began a series of short programs working at the university design studios. They worked with graduate students in …

Textiles, Scholarship, And Art Education: An Art College Perspective, Wendy Landry

Textile Society of America: Symposium Proceedings

In many communities the art college is the last formal refuge of active textile-making knowledge and heritage. This location appears to value playful, risky, or challenging material explorations which might result in creative design or meaningful visual expression. This should be the best environment for cultivating adventurous students able to integrate a wide range of experience and resources towards generating new ideas for interesting contemporary textiles. It could be a good place in which to discover how textiles contribute to human experience and history, and how they are meaningful. However, I submit that this art environment is still detrimental to …

Black Image And Identity African-American Art From The Permanent Collection, Daniel A. Siedell

Sheldon Museum of Art: Catalogs and Publications

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 …

Each year twenty works from this collection are …

Judith Burton: Visual Nuances, Daniel A. Siedell

Sheldon Museum of Art: Catalogs and Publications

The history and development of the pictorial tradition in the West is punctuated by many formal and conceptual tensions, among them the tension between representation and abstraction, between mimesis and personal expression, between objectivity and subjectivity, between the artist and the viewer. The Sheldon Memorial Art Gallery and Sculpture Garden is pleased to present Judith Burton: Visual Nuances, a solo exhibition featuring twenty-four paintings and two monotypes by an important Nebraska artist whose aesthetic expression succeeds in celebrating these many tensions and formal subtleties that are such an important part of our visual arts tradition.

However, much attention-perhaps too …

Lessons Learned In Applying The U.S. Epa Proposed Cancer Guidelines To Specific Compounds, Melvin E. Andersen, M. Elizabeth Meek, Gary A. Boorman, David J. Brusick, Samuel M. Cohen, Yvonne P. Dragan, Clay B. Frederick, Jay I. Goodman, Gordon C. Hard, Ellen J. O'Flaherty, Denise E. Robinson

United States Public Health Resources

An expert panel was convened to evaluate the U.S. Environmental Protection Agency’s “Proposed Guidelines for Carcinogen Risk Assessment” through their application to data sets for chloroform (CHCl₃) and dichloroacetic acid (DCA). The panel also commented on perceived strengths and limitations encountered in applying the guidelines to these specific compounds. This latter aspect of the panel’s activities is the focus of this perspective. The panel was very enthusiastic about the evolution of these proposed guidelines, which represent a major step forward from earlier EPA guidance on cancer-risk assessment. These new guidelines provide the latitude to consider diverse scientific data …

A Mao A Minute Real Computers As Virtual Weavers, Lisa Lee Peterson

Textile Society of America: Symposium Proceedings

In the mid-1970s, Chinese goods began to flood American markets as a result of President Richard Nixon's historic visit to China in February 1972. Among such trade items as blue Mao jackets and caps with red enameled stars, proletarian black cloth shoes, and little red books were photograph-like woven portraits of the potentates of Communism: Stalin, Lenin, Marx, and Chairman Mao.

Convinced that China had computer-and-loom systems that could instantly weave textile renditions of photographs, I raced off to the textile industry in New York City to weave on these digital wonders. Industry experts quickly disabused me of this idea. …

Fiber Art/Works Of Art: Positioning And Perception In The Marketplace, Alice Zrebiec

Textile Society of America: Symposium Proceedings

Contemporary works made of fiber or incorporating textile techniques frequently encounter an identity crisis. Craft? Fiber Art? Fine Art? How do these descriptions limit marketability and representation of the work, or, conversely, open up new horizons for talented artists? The owners of five galleries presented their viewpoints with specific reference to the focus of their galleries, the artists they represent, and the context in which they present textile-related works to the viewing public. They addressed the following issues: How did these galleries evolve their specific visions? Where is their emphasis: on materials and techniques, craftsmanship, or artistic content and expression? …

Nature As Code, Ruth Scheuing

Textile Society of America: Symposium Proceedings

In order to explore 'nature as code', I will look first at the complexities involved in naming and defining "nature" and the assumptions that have historically associated women with nature. I will focus on historical gardens and floral patterns in textiles as cultural constructs of nature. Specifically I will focus on the differences between French formal gardens of the seventeenth century and the picturesque and naturalist English gardens of the eighteenth century. I will examine how these gardens are reflected in textile designs that use floral motifs. Finally, I hope to provide some explanation of the influences of industrial and …

Surviving The Flood: Plastron Respiration In The Non-Tracheate Arthropod Phrynus Marginemaculatus (Amblypygi: Arachnida), Eileen Hebets, Reginald F. Chapman

Eileen Hebets Publications

Specimens of Phrynus marginemaculatus can remain responsive when submerged in water for more than 24 hours. Behavioral data indicate that P. marginemaculatus utilizes dissolved oxygen from the surrounding water. Scanning electron miscroscopy and light microscope sections show cuticular modifications for plastron respiration. All previous examples of plastron respiration have involved animals with tracheal systems, but amblypygids respire through the use of two pairs of book lungs. This study provides the first example of plastron respiration not only in the order Amblypygi, but also, in any non-tracheate arthropod.

Expression Of A Dominant-Negative Mutant Of P21ras Inhibits Induction Of Nitric Oxide Synthase And Activation Of Nuclear Factor-Kb In Primary Astrocytes, Kalipada Pahan, Xiaojuan Lu, Michael J. Mckinney, Charles Wood, Faruk G. Sheikh, John R. Raymond

School of Biological Sciences: Faculty Publications

The present study underlines the importance of p21ras in regulating the inducible nitric oxide synthase (iNOS) in primary astrocytes. Bacterial lipopolysaccharides induced the GTP loading of p21ras, and the expression of a dominant-negative mutant of p21ras (Dp21ras) inhibited lipopolysaccharide-induced GTP loading in rat primary astrocytes. To delineate the role of p21ras in the induction of iNOS, we examined the effect of Dp21ras on the expression of iNOS and the production of nitric oxide. It is interesting that expression of Dp21ras markedly inhibited the production of nitric oxide and the expression of iNOS in lipopolysaccharide- and pro-inflammatory cytokine (tumor necrosis factor-a, …

Bovine Blastocyst-Derived Trophectoderm And Endoderm Cell Cultures: Interferon Tau And Transferrin Expression As Respective In Vitro Markers, Neil C. Talbot, Thomas J. Caperna, J. Lannett Edwards, Wes Garrett, Kevin D. Wells, Alan D. Ealy

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Continuous cultures of bovine trophectoderm (CT-1 and CT- 5) and bovine endoderm (CE-1 and CE-2) were initiated and maintained on STO feeder cells. CT-1 and CT-5 were derived from the culture of intact, 10- to 11-day in vitro-produced blastocysts. CE-1 and CE-2 were derived from the culture of immunodissected inner cell masses of 7- to 8-day in vitro-produced blastocysts. The cultures were routinely passaged by physical dissociation. Although morphologically distinct, the trophectoderm and endoderm both grew as cell sheets of polarized epithelium (dome formations) composed of approximately cuboidal cells. Both cell types, particularly the endoderm, grew on top …

Wreath-Laying In Poet's Corner, Westminster Abbey, Chris Smith

The George Eliot Review Online, ISSN: 2831-5375

The Guest of Honour was The Rt Hon. Chris Smith, MP, Secretary of State for Culture, Media and Sport. The Address he gave is summarized below:

Mr. Smith is a great admirer of George Eliot and it is said that he takes with him on holiday each year one of George Eliot's novels! He began by noting that he was standing next to the memorial stone to Henry James and he reminded us of James's admiration for George Eliot. Henry James wrote on 5 March 1873 'a marvellous mind throbs in every page of Middlemarch. It raises the standard of …

Annual Report 1999, Kathleen Adams

The George Eliot Review Online, ISSN: 2831-5375

During 1999 we were unusually busy in planning the extra events to take place in 2000. Before I began this report I had spent a few weeks updating the Story of the George Eliot Fellowship which had been published for our fiftieth anniversary in 1980 and now needed a further 20 busy years added. So, as I began the report of activities for 1999 I had many other years buzzing around in my head. However, 1999 is now clear of those seventy years, and I am happy to begin with the news that 1999 was another profitable year for the …
