Tools, Techniques And Teamwork: Transferring New Technologies For Wildlife Management, Conservation And Economic Development, John Eisemann, Gail Keirn

United States Department of Agriculture Wildlife Services: Staff Publications

Did you ever wonder who invented radio telemetry? Or breakaway snares? What about the bird repellent methyl anthranilate or the livestock protection collar? These and many other tools used in wildlife damage management resulted from creative thinking by biologists, technicians, researchers and managers working to solve complex wildlife issues. Over the past 90 years, these “aha moments” within the U.S. Department of Agriculture’s Wildlife Services program have ranged from developing novel scare devices, traps and vaccines to exploiting an animal’s visual capabilities to stop unwanted behaviors. Once discovered, these unique ideas may lead to practical, feasible and cost-effective wildlife damage …

Prejudiced Commodities: Understanding Knowledge Transfer From India To Britain Through Printed And Painted Calicoes, 1720-1780, Aditi Khare

Textile Society of America: Symposium Proceedings

The eighteenth-century trade in calico between Europe and India was a function of global textile manufacture, exchange, and consumption on multiple levels. This trade had several political, cultural, and economic consequences— the most important of which, I suggest, was the transfer of useful knowledge from artisanal oral textile traditions in India to the receptive, commercial, and nascent cotton printing industry in Europe.

This paper explores the contribution of Indian cotton printing knowledge towards the development of Europe’s cotton industry and, consequently, its dissemination through European knowledge networks. In particular, the largely overlooked chemical knowledge pertaining to dyes and mordants responsible …

Schoolgirl Embroideries & Black Girlhood In Antebellum Philadelphia, Kelli Racine Coles

Textile Society of America: Symposium Proceedings

Embroideries stitched by girls at schools for Black children in the eighteenth and nineteenth centuries are rare finds in the antiques world. The few embroideries likely stitched by Black schoolgirls that do survive often offer historical evidence in the form of the names of their makers’ schools stitched onto their embroideries. Yet there is little scholarship on these embroideries or the education these schoolgirls were pursuing while creating their samplers. In scholarship using material culture as primary evidence, these embroideries provide valuable clues about the lives of Black girls in northern cities during the antebellum period. My work examines the …

Plants In The Tapestry (Literally), Ann H. Peters, Adriana Soldi S.

Textile Society of America: Symposium Proceedings

Among our studies of ancient Peruvian textiles created in tapestry technique, we have come across some surprising elements, both in the warp and the weft. Andean textiles created over the past 10,000 years have been preserved in certain locations along the Pacific desert coast. They are usually preserved in the cloth bundles that protect and adorn the dead, and composed of fibers from native cotton varieties of Amazonian ancestry, the hair of highland ancestors of today’s llama and alpaca, maguey leaves from the mid-valley canyons, and reeds from coastal marshes. Garment forms, techniques and imagery can indicate textiles produced in …

A Compared Study Of Miao Embroidery And Ancient Chinese Embroidery: The Cultural And Historical Significances, Tomoko Torimaru

Textile Society of America: Symposium Proceedings

The Miao people of Guizhou province, China, use two different types of chain stitch. One is a standard chain stitch similar to the Western style. The other one, which I termed “ancient” chain stitch, is distinctly different in execution and appearance, and it is a technique that only Miao practice currently.

Numerous examples of fine chain stitch embroidery have been excavated from archeological sites in China, including the Jiangling Mashan No.1 Chu Tomb, Jingzhou, Hubei, Warring States period (770–221 BC) and the Mawangdui No.1 Tomb, Changsha, Hunan, Western Han period (206 BC–AD 8). These extant embroideries clearly illustrate a unique …

Perforin-Deficient Car T Cells Recapitulate Late-Onset Inflammatory Toxicities Observed In Patients, Kazusa Ishii, Marie Pouzolles, Christopher D. Chien, Rebecca A. Erwin-Cohen, M. Eric Kohler, Haiying Qin, Haiyan Lei, Skyler Kuhn, Amanda K. Ombrello, Alina Dulau-Florea, Michael A. Eckhaus, Haneen Shalabi, Bonnie Yates, Daniel A. Lichtenstein, Valérie S. Zimmermann, Taisuke Kondo, Jack F. Shern, Howard A. Young, Naomi Taylor, Nirali N. Shah, Terry J. Fry

United States Public Health Resources

Late-onset inflammatory toxicities resembling hemophagocytic lymphohistiocytosis (HLH) or macrophage activation syndrome (MAS) occur after chimeric antigen receptor T cell (CAR T cell) infusion and represent a therapeutic challenge. Given the established link between perforin deficiency and primary HLH, we investigated the role of perforin in anti-CD19 CAR T cell efficacy and HLH-like toxicities in a syngeneic murine model. Perforin contributed to both CD8+ and CD4+ CAR T cell cytotoxicity but was not required for in vitro or in vivo leukemia clearance. Upon CAR-mediated in vitro activation, perforin-deficient CAR T cells produced higher amounts of proinflammatory cytokines compared with WT CAR …

Glitched Metaphors: Dysfunction In Hand-Woven Digital Jacquard, Gabe Duggan

Textile Society of America: Symposium Proceedings

This presentation demonstrates various ways in which the TC1 has supported my work’s exploration of tension, balance, and precarity. By embracing and pushing expectations of traditional fiber work, these weavings question inequalities within contemporary performances of gender and exhibitions of power. My work on the TC1/TC2 digital jacquard loom has been primarily tethered to one specific machine with which I have shared a personal past and future for just over a decade. Through this technology I have built and negated tension, challenging a broad range of power dynamics. My work with this TC1 seeks to exploit and balance this technology …

A Tale Of Two Sisters: Invisibility, Marginalization And Renown In A 20th Century Textile Arts Revitalization Movement In New Mexico, Suzanne P. Macaulay

Textile Society of America: Symposium Proceedings

While this presentation does not address oppression in the global textile industry and injustices to leagues of anonymous enslaved women workers, it does raise questions about the vicissitudes of fame and obscurity of two women relative to artistic creation and textile arts revitalization efforts. This is the story of two Varos sisters, who married two Graves brothers, and lived in Carson, New Mexico. In the early 1930s Frances and Sophie Graves with their extended families repaired Spanish colonial textiles for the Santa Fe market. At some point they began to recreate traditional Spanish colonial-type colcha embroideries from recycled materials salvaged …

Shared Provenance: Investigating Safavid-Mughal Cultural Exchange Through Luxury Silks In The Sixteenth And Seventeenth Centuries, Nazanin Hedayat Munroe

Textile Society of America: Symposium Proceedings

When examining silk textiles attributed to the early modern Persianate world, there is always some uncertainty as to whether they were produced in Safavid Iran or Mughal India. The confusion is warranted: the two courts share many of the same ideas, images, and even family connections, creating a broad cultural overlap. This becomes apparent in the arts from the mid-sixteenth century onwards, as politics and patronage prompted the migration of key Safavid artists, including weavers, from Iran to Mughal India. As Persian painting was developed in the royal atelier, luxury silks were also produced with Safavid techniques.

Examining these imported …

Colcha Circle: A Stitch In Northern New Mexico Culture, Olimpia Newman, Rebecca Abrams

Textile Society of America: Symposium Proceedings

Colcha embroidery is folk art, characteristic of northern New Mexico history, traditions, and a form of cultural expression that has not been researched and documented sufficiently. It has been practiced in private homes and small circles as a result of commissions or economic development programs, as has also been the case in the San Luis Valley, Colorado. Despite the exposure offered by local markets and demonstrations during events in New Mexico, the embroidery is in many ways an unknown technique, even to the next generation.

This video captures a candid discussion among eleven colcha artists, some of whom are entering …

“It’S Like They Don’T Recognize What I Bring To The Classroom”: African Immigrant Youths’ Multilingual And Multicultural Navigation In United States Schools, Lydiah Kananu Kiramba, Alex Kumi-Yeboah, Anthony Mawuli Sallar

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Discourses of African immigrant children are rare in educational research. As such, African immigrant educational experiences are often obscured (in part, owing to the model minority myth about Africans based on higher education degrees received by African immigrants), as well as the actual experiences and realities for African immigrant K-12 students. This qualitative study examines cross-cultural educational experiences of 30 Black African immigrant youth in U.S. schools. The findings reveal multiple participants’ struggles with cultural and linguistic differences, stereotypes and marginalization in the school environment, low expectations from teachers, and adjusting to new schooling practices. The African youths’ voices exhibited …

The Roles Of Language, Communication, And Discourse In Power: A Series Of Critical (Reaction) Essays, Alessia Barbici-Wagner

The Nebraska Educator: A Student-Led Journal

The following is a conceptual paper consisting of a series of short, critical essays written for the “Language and Power” course taught by Professor Loukia K. Sarroub at the University of Nebraska-Lincoln during Fall 2019. The purpose of these essays is to understand the power of language, communication, and discourse in society and in education. Each essay is itself unique and connected to the others and explores the role of language in community and institutional settings. Language is intrinsically connected to culture, and most societies show their hierarchal power through it. For example, the short essay “‘Ketchup’ with Social Norms” …

Genomic Analysis Of Igg Antibody Response To Common Pathogens In Commercial Sows In Health-Challenged Herds, Leticia P. Sanglard, Piggen Canada, Benny E. Mote, Philip Willson, John C.S. Harding, Graham S. Plastow, Jack C.M. Dekkers, Nick V.L. Serão

Department of Animal Science: Faculty Publications

Losses due to infectious diseases are one of the main factors affecting productivity in the swine industry, motivating the investigation of disease resilience-related traits for genetic selection. However, these traits are not expected to be expressed in the nucleus herds, where selection is performed. One alternative is to use information from the commercial level to identify and select nucleus animals genetically superior for coping with pathogen challenges. In this study, we analyzed the genetic basis of antibody (Ab) response to common infectious pathogens in health-challenged commercial swine herds as potential indicator traits for disease resilience, including Ab response to influenza …

An Open-Sourced, Web-Based Application To Improve Our Ability To Understand Hunter And Angler Purchasing Behavior From License Data, Nathaniel B. Price, Christopher J. Chizinski, Joseph J. Fontaine, Kevin L. Pope, Micaela Rahe, Jeff Rawlinson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

State fish and wildlife agencies rely on hunters and anglers (i.e., sportspersons) to fund management actions through revenue generated from license sales and excise taxes on hunting and fishing equipment. There is a need to develop new techniques that bridge the information gap on participation and provide agencies with an understanding of sportspersons at a resolution that can more directly inform efforts to engage sportspersons. Monitoring sportsperson participation using information about their license-purchasing behavior has the potential to reveal important patterns in recruitment (first-time purchase of a hunting or fishing license), retention (continued purchase of licenses across multiple years), and …

Towards A Complex Framework Of Teacher Learning-Practice, Kathryn J. Strom, Kara Mitchell Viesca

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Although many researchers agree that teaching is complex and contextually situated, dominant conceptions of teacher learning, and the enactment of such learning in practice, tend to be linear and reductionist. Because simplistic conceptualizations of teaching activity have far-reaching impact on teachers, students, and school systems, generating a complex theory of teacher learning-practice is nothing short of an ethical imperative. To tackle this task, we draw from an emerging body of teacher education scholarship that we consider the beginning of a ‘complex turn’. Drawing on this literature, we distill a set of conceptual shifts that, together, offer a set of theoretical …

Hidden Stories/Human Lives: Proceedings Of The Textile Society Of America 17th Biennial Symposium, October 15-17, 2020--Full Program With Abstracts & Bios

Textile Society of America: Symposium Proceedings

The theme Hidden Stories/Human Lives presents opportunities to reveal complex and hidden stories of global textile making and coincides with the 100th anniversary of the 19th Amendment to the United States Constitution. Yet, just as the voices of women of color, marginalized by the suffrage movement, are only now being recognized, the stories of the many human lives that have contributed—directly and indirectly—to textile making, including enslaved people, immigrant entrepreneurs, and industrial laborers, remain untold. With this symposium, we hope to get “behind the curtain” to explore the wider human network engaged in textile production, bringing to light hidden stories …

Inscription, Iconography, And The Individual: A Late Antique Textile From The Harvard Art Museums In Context, Katherine M. Taronas

Textile Society of America: Symposium Proceedings

A small but distinct group of early Byzantine textiles from Egypt (dating between the fourth and sixth centuries) uses woven words and textual symbols for their primary decoration. Ornamented with bold letterforms created in brilliant colors, these objects are all inscribed with personal names—the names of individual men and women for whose lives we possess no other certain evidence. Far from simple labels indicating ownership, these names are integral parts of the textiles’ design and function both as text and as image. Investigating the epigraphic nuances, iconography, styles, and formats of these textiles will allow us to make some inferences …

Instability Of Glucocorticoid Metabolites In Coyote Scats: Implications For Field Sampling, Erika T. Stevenson, Eric M. Gese, Lorin A. Neuman-Lee, Susannah S. French

United States Department of Agriculture Wildlife Services: Staff Publications

Studying physiologic stress responses can assist in understanding the welfare of animals. One method of measuring the physiologic stress response is evaluating concentrations of glucocorticoid metabolites in feces. Previously, using an adrenocorticotropic hormone challenge, we found fecal glucocorticoid metabolite levels were a reliable indicator of physiologic stress response in coyotes (Canis latrans). We determine whether glucocorticoid metabolite concentrations remain stable when collecting feces over a 2-week period, a timeframe commonly used in scat surveys for wild canids. We collected feces from 6 captive coyotes maintained at the U.S. Department of Agriculture, Wildlife Services, National Wildlife Research Center, Predator …

Changes In Lipid Profiles Of Epileptic Mouse Mode, Alicia Johnson, Ryan A. Grove, Deepak Madhavan, Cory H.T. Boone, Camila Pereira Braga, Hannah Kyllo, Kaeli K. Samson, Kristina A. Simeone, Timothy A. Simeone, Tomáš Helikar, Corrine K. Hanson, Jiri Adamec

Department of Biochemistry: Faculty Publications

Introduction Approximately 1% of the world’s population is impacted by epilepsy, a chronic neurological disorder characterized by seizures. One-third of epileptic patients are resistant to AEDs, or have medically refractory epilepsy (MRE). One non-invasive treatment that exists for MRE includes the ketogenic diet (KD), a high-fat, low-carbohydrate diet. Despite the KD’s success in seizure attenuation, it has a few risks and its mechanisms remain poorly understood. The KD has been shown to improve metabolism and mitochondrial function in epileptic phenotypes. Potassium channels have implications in epileptic conditions as they have dual roles as metabolic sensors and control neuronal excitation.

New State And Island Records Of Coccinellidae (Coleoptera) In Hawai‘I, Usa, Louis S. Hesler, William D. Perreira, Dana Anne Yee, Joshua H.S. Silva

Insecta Mundi

Three new records of Coccinellidae (Coleoptera) are recorded within the state of Hawai‘i, USA. Diomus roseicollis (Mulsant, 1853) is newly recorded from the state based on four specimens collected on the island of O‘ahu. Cycloneda sanguinea sanguinea (Linnaeus, 1763) and Brumoides suturalis (Fabricius, 1789), both already established in the state, are newly recorded from the island of Hawai‘i. Additional sampling is recommended to determine the distribution of D. roseicollis within the island of O‘ahu. Further surveys are warranted to determine particular habitats and prey for D. roseicollis, C. sanguinea sanguinea, and B. suturalis in …

Anelaphus aspera (Knull, 1962), Anelaphus bupalpa (Chemsak, 1991), and Anelaphus mag­nipunctatus (Knull, 1934) …

On Speciation And Hybridization Among Closely Related Species: Establishing An Experimental Breeding Lineage Between Two Species Of Automeris Hübner Moths (Lepidoptera: Saturniidae) And Implications For Taxonomy, Andrei Sourakov, Cassandra Doll, Alyssa M. Quinn, Lei Xiao, Eric Anderson

Insecta Mundi

Many species of plants and a few species of animals are believed to have resulted from hybridization of parental species, and the ability of species to occasionally hybridize in captivity and in nature is even more widespread. In the present study, we describe a hybridization experiment conducted in the laboratory between the sexually dimorphic Automeris io (Fabricius), a widespread, variable species ranging from Canada to Costa Rica, and its congener A. louisiana (Ferguson and Brou), a more local, sexually monomorphic species (Lepidoptera: Saturniidae). The A. louisiana populations occur in a highly specialized habitat—the coastal marshland along the Gulf of Mexico …

Host-Use Patterns Of Canopy-Inhabiting Click Beetles (Coleoptera: Elateridae) In A Lowland Rainforest In Southern Venezuela, Susan Kirmse, Paul J. Johnson

Insecta Mundi

The arboreal click beetle fauna (Coleoptera: Elateridae) in a lowland tropical rainforest in south­ern Venezuela was observed and collected by means of a tower crane for a full year. The evaluation of the elaterid assemblage is part of a general survey of Coleoptera associated with several canopy trees. The Elat­eridae represented the tenth most species-rich beetle family in the canopy of the crane plot and was therefore selected for a detailed analysis of host-use patterns. In total, 20 species of Elateridae with 402 adult indi­viduals were sampled, including seven singletons. Species were either flower visiting (Aeolus Eschscholtz and Cosmesus …

The Role Of Myopic Loss Aversion In Pre-Harvest Grain Marketing, Iyore Eronmwon

Department of Agricultural Economics: Dissertations, Theses, and Student Research

In this study, we investigate the role of myopic loss aversion (MLA) risk preferences on pre-harvest grain marketing decisions using a laboratory experiment. Prospect theory parameters were estimated to measure MLA. We estimated a power function for utility and obtained power estimates indicating linear utility for gains and concave utility for losses. We obtained a loss aversion parameter estimate that suggests the presence of loss aversion. We found evidence of probability weighting for both gains and losses. We classified individuals into three categories based on their MLA status. They are no NMLA, MLA, and high loss aversion (HLA). We observed …

A Practical Guide To Mechanistic Systems Modeling In Biology Using A Logic-Based Approach, Anna Niarakis, Tomáš Helikar

Department of Biochemistry: Faculty Publications

Mechanistic computational models enable the study of regulatory mechanisms implicated in various biological processes. These models provide a means to analyze the dynamics of the systems they describe, and to study and interrogate their properties, and provide insights about the emerging behavior of the system in the presence of single or combined perturbations. Aimed at those who are new to computational modeling, we present here a practical hands-on protocol breaking down the process of mechanistic modeling of biological systems in a succession of precise steps. The protocol provides a framework that includes defining the model scope, choosing validation criteria, selecting …

Uncertainties Abound In Nebraska Livestock Market Forecasts, Elliott James Dennis

Extension Farm and Ranch Management News

About one of the only things certain about forecasts this year has been the great deal of uncertainty. Numerous “novel” situations have confronted the industry making it difficult to estimate price magnitudes rather than just price direction. Clustered plant closures, government quarantine restrictions, and increasing at home phone consumption are just a few of the major issues the beef industry has had to tackle in the last six to eight months. Some things have returned to “normal” such as packing plant capacity and food service demand. Others are still in ongoing recovery.

Who knows what “normal” or “standard operating procedure” …

Comparing Profitability And Management Factors Across Operation Type: Independent Vs. Contract Growing, Elliott James Dennis

Extension Farm and Ranch Management News

First paragraph:

There is strong local and national interest in adding hog barns to existing row crop operations. Declining on farm income over the past several years has accelerated this interest. Grain operations cite diversifying farm income, adding another family to the farm operation, and/or replacing commercial fertilizer expense as the primary reasons for adding a hog barn.
