Global Discontents, Priyadarshini A. Khatri

Theses and Dissertations

My creative project explores toys as means to express economic issues of globalization. By exploiting the educational and imaginative aspects of toys for adults and children, I intend to reflect on the impact and pressures of globalization on employment, technology and environment. In creating these toys I hope to make a visual statement concerning critical issues of human survival, sustainability and the divisive side of globalization.

Objects And Images, Mary Bergshneider Magneson

Theses and Dissertations

I create to emphasize the aesthetic or beauty of an object. When I begin a work, I feel the influence of the many photos I am constantly looking at and analyzing. I look at how light affects color, how light defines form, and how patterns are created by repeated shapes. I try to reproduce the things I see, but with dramatic impact by enlarging shapes and emphasizing colors. While my paintings are about pure aesthetics, my books are social commentary.

Omnivory By The Small Cosmopolitan Hydromedusa Aglaura Hemistoma, Sean Colin, John H. Costello, William M. Graham, John Higgins Iii

Arts & Sciences Faculty Publications

We investigated the feeding of the small hydromedusa, Aglaura hemistoma (bell diameter < 4 mm), to determine if it occupies a trophic position similar to that of large medusae. Feeding was examined using gut-content analysis of preserved and unpreserved medusae and by analyzing prey-capture events using microvideographic techniques. Analysis of gut contents and prey-capture events revealed that A. hemistoma fed heavily on protistan prey and that it possessed a prey-capture mechanism, specifically a feeding current,that is effective at entraining and capturing protists with low motility. We suggest that many species of small hydromedusae possess prey-capture mechanisms adapted to capture small protistan prey and that many of these small hydromedusae feed omnivorously on microplanktonic prey. The trophic roles of small hydromedusae in different systems are not understood and more studies are needed. However, based on their often high abundances and the cosmopolitan nature, if small hydromedusae …

Prorocentrum Minimum(Clone Exuv) Is Nutritionally Insufficient, But Not Toxic To The Copepod Acartia Tonsa, Hans G. Dam, Sean Colin

Arts & Sciences Faculty Publications

This study tested whether the dinoflagellate Prorocentrum minimum is nutritionally insufficient or toxic to the copepod Acartia tonsa. Experiments were carried out with adult female A. tonsa and the P. minimum clone Exuv, both isolated from Long Island Sound. Initially, the functional and numerical responses of A. tonsa feeding on exponentially growing P. minimum cells were characterized. These experiments revealed that A. tonsa readily ingested P. minimum cells, up to the equivalent of 200% of body carbon day⁻¹, but egg production was relatively low, with a maximum egg production rate of 22% of body carbon day …

Human Rights And Bioethics: Formulating A Universal Right To Health, Health Care, Or Health Protection?, George P. Smith, Ii

Vanderbilt Journal of Transnational Law

Codifying, and then implementing, an international right to health, health care, or protection is beset with serious roadblocks--foremost among them being contentious issues of indeterminacy, justiciability, and progressive realization.

Although advanced--and to some degree recognized under the rubric of a social or cultural entitlement within the law of human rights and, more particularly, the U.S. Declaration on Human Rights, together with International Covenant on Economic, Social and Cultural Rights (ICESCR), the International Covenant on Civil and Political Rights, the European Convention on Human Rights, and presently UNESCO's Draft Declaration on Universal Norms on Bioethics--attainment of such a universal right to …

Ctla-4 Signaling Regulates The Intensity Of Hypersensitivity Responses To Food Antigens, But Is Not Decisive In The Induction Of Sensitization, Femke Van Wijk, Sanne Hoeks, Stefan Nierkens, Stef J. Koppelman, Peter Van Kooten, Louis Boon, Leon M.J. Knippels, Raymond Pieters

Department of Food Science and Technology: Faculty Publications

Although food allergy has emerged as a major health problem, the mechanisms that are decisive in the development of sensitization to dietary Ag remain largely unknown. CTLA-4 signaling negatively regulates immune activation, and may play a crucial role in preventing induction and/or progression of sensitization to food Ag. To elucidate the role of CTLA-4 signaling in responses to food allergens, a murine model of peanut allergy was used. During oral exposure to peanut protein extract (PPE) together with the mucosal adjuvant cholera toxin (CT), which induces peanut allergy, CTLA-4 ligation was prevented using a CTLA-4 mAb. Additionally, the effect of …

Decline And Recovery Of A High Arctic Wolf-Prey System, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

A long-existing system of wolves (Canis lupus), muskoxen (Ovibos moschatus), and arctic hares (Lepus arcticus) in a 2600 km² area of Canada’s High Arctic (80° N latitude) began collapsing in 1997 because of unusual adverse summer weather but recovered to a level at which all three species were reproducing by 2004. Recovery of wolf presence and reproduction appeared to be more dependent on muskox increase than on hare increase.

Bears Remain Top Summer Predators, Shannon M. Barber, L. David Mech, P. J. White

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

In the ten years since wolves (Canis lupus) were restored to Yellowstone National Park (YNP), elk (Cervus elaphus) numbers have substantially decreased. The northern range elk herd is the largest elk herd in Yellowstone, and constitutes the majority of the park’s elk population. During 1994–2005, early winter counts of northern Yellowstone elk decreased from 19,045 to 9,545. Also, during winters 2000–2004, calf:cow ratios declined from 29:100 to 12:100, and were among the lowest recorded during the past several decades. Though many factors (e.g., predation, hunting, and drought) likely contributed to this decreasing abundance and low recruitment, …

Replication And Encapsidation Of Papillomaviruses In Saccharomyces Cerevisiae, Peter C. Angeletti

Nebraska Center for Virology: Faculty Publications

Improvements in methodologies to recapitulate and study particular biological functions of the

papillomavirus life cycle have led to great advances in our knowledge of these viruses. Described in

this chapter are techniques that allow low-copy and high-copy replication of full-length human

papillomavirus (HPV) genomes, as well as assembly of virus-like particles, in Saccharomyces

cerevisiae (yeast). This system has several distinct advantages that make it an attractive complement

to the well-established raft-culturing system. First, yeast are inexpensive, rapid, and simple to culture

in the lab. Second, they provide an ever-widening array of genetic tools to analyze HPV functions

—most recently notable, …

Husbandry Of Wild-Caught Greater Sage-Grouse, Paul Oesterle, Robert Mclean, Michael Dunbar, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

This study reports the first successful husbandry and breeding in captivity of wild-caught greater sage-grouse (Ccntroccrcus urophasianus). In October 2003, 2 1 hatch-year greater sage-grouse were trapped in northwestern Nevada and transported to Fort Collins, Colorado. We held grouse in pens at the United States Department of Agriculture's National Wildlife Research Center for 8 months. We offered a varied diet, including native food items such as sagebrush (Arternisia tridentata and A. tripartita) and yarrow (Achilles millefolium). We housed grouse in a large flight pen and allowed to them freerange as one flock. Mortdlity rate was 16.7%. Several of the grouse …

Marketing Locally Produced Foods: Consumer And Farmer Opinions In Washington County, Nebraska, Mindi L. Schneider, Charles A. Francis

Department of Agronomy and Horticulture: Faculty Publications

Local food system potentials were studied in Washington County, Nebraska, United States. As a departure from most studies of locally based systems, farmers were surveyed in addition to consumers for potential participation. Data about the current food system and opinions and preferences for local production, marketing, and purchasing of food were collected using self-administered mail questionnaires. The response rate was 35% for the farmer survey and 37% for the consumer survey. Results indicated that, on the farming side of the food system, conventional corn and soybean production and marketing predominated in Washington County, and farmer interest in producing for local …

Species Diversity And Functional Composition Of Pastures That Vary In Landscape Position And Grazing Management, John A. Guretzky, Kenneth J. Moore, E. Charles Brummer, C. Lee Burras

Department of Agronomy and Horticulture: Faculty Publications

The productivity of grasslands depends in part on their diversity of species and functional composition. Our objective was to examine the effects of three landscape positions (summit, backslope, and toe-slope) and three stocking systems (continuous, rotational, and non-grazed) on species diversity and percentage of cover of grass, legume, and weed species functional types in southeastern Iowa pastures.Data were collected in 0.2-m² plots randomly distributed throughout each of four replicate pastures in spring and summer 2000 and 2001. Backslope landscape positions within pastures managed with either continuous or rotational stocking contained the greatest overall diversity of species. Across years, overall …

Evaluating Livestock System Environmental Performance With Whole-Farm Nutrient Balance, Richard K. Koelsch

Department of Agricultural and Biological Systems Engineering: Faculty Publications

As a part of the USEPA’s concentrated animal feeding operation (CAFO) final rule, all CAFOs are required to develop and implement a nutrient management plan (NMP). The USEPA’s emphasis on better management of nutrients appropriately targets a critical environmental issue associated with animal production. The concentration of animals in livestock feeding operations, often separate from feed grain production, requires importing of substantial quantities of feed nutrients. Due to the inefficiencies of nutrient utilization in livestock production, quantities of nitrogen (N) and phosphorus (P) in manure greater than can be utilized in local crop production often result. With the focus of …

Extraction Of Lipids From Grain Sorghum Ddg, L. Wang, Curtis L. Weller, K. T. Hwang

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Soxhlet and recirculated solvent extraction methods were used to extract lipid materials from grain sorghum DDG. The lipid content in DDG with a moisture content of 6.7% (dry basis) was as high as 9.32% of the dried DDG as determined by Soxhlet extraction with n-hexane. There was a slight increase in the lipid yield from 9.21% to 9.68% when the moisture contents increased from 2.1% to 17.4% (d.b.). Thin-layer chromatography (TLC) analysis showed that the sorghum lipids were composed of triacylglycerols, fatty acids, fatty alcohols, fatty aldehydes, free sterols, wax esters, and steryl esters. A bench-scale recirculated extraction system was …

Policosanol Contents And Compositions In Wax-Like Materials Extracted From Selected Cereals Of Korean Origin, Keum Taek Hwang, Ji Eun Kim, Curtis L. Weller

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Policosanols. long-chained alcohols. have been reported to have beneficial physiological activities. Content and composition of policosanols in wax-like materials extracted from selected cereals of Korean origin were determined. Wax-like materials were extracted using hot hexane. Yields of wax-like materials from unpolished grain sorghum, polished grain sorghum. brown rice. purple rice, wheat, and maize were 223, 37, 33, 61, 10, and 10 mg/100 g of dry kernels, respectively. Policosanol contents, as determined using HPLC, in the wax-like materials from the cereals were 33, 29, 6.0, and 2% (w/w, db), respectively. Major alcohols in the policosanols from grain sorghum were octacosanol and …

Regulation Of Enteric Endophytic Bacterial Colonization By Plant Defenses, A. Leonardo Iniguez, Yuemei Dong, Heather D. Carter, Brian M. M. Ahmer, Julie M. Stone, Eric W. Triplett

Department of Biochemistry: Faculty Publications

Bacterial endophytes reside within the interior of plants without causing disease or forming symbiotic structures. Some endophytes, such as Klebsiella pneumoniae 342 (Kp342), enhance plant growth and nutrition. Others, such as Salmonella enterica serovar Typhimurium (S. typhimurium), are human pathogens that contaminate raw produce. Several lines of evidence are presented here to support the hypothesis that plant defense response pathways regulate colonization by endophytic bacteria. An ethyleneinsensitive mutant of Medicago truncatula is hypercolonized by Kp342 compared to the parent genotype. Addition of ethylene, a signal molecule for induced systemic resistance in plants, decreased endophytic colonization in Medicago spp. …

Roles For Nutrients In Epigenetic Events, Anna M. Oommen, Jacob B. Griffin, Gautam Sarath, Janos Zempleni

Gautam Sarath Publications

The field of epigenetics is the study of modifications of DNA and DNA-binding proteins that alter the structure of chromatin without altering the nucleotide sequence of DNA; some of these modifications may be associated with heritable changes in gene function. Nutrients play essential roles in the following epigenetic events. First, folate participates in the generation of S-adenosylmethionine, which acts as a methyl donor in the methylation of cytosines in DNA; methylation of cytosines is associated with gene silencing. Second, covalent attachment of biotin to histones (DNA-binding proteins) plays a role in gene silencing and in the cellular response to DNA …

Terrestrial Behavior Of Ateles Spp., Christina J. Campbell, Filippo Aureli, Colin A. Chapman, Gabriel Ramos-Fernández, Kim Matthews, Sabrina E. Russo, Scott Suarez, Laura Vick

School of Biological Sciences: Faculty Publications

Spider monkeys (Ateles spp.) are well known for their highly arboreal lifestyle, spending much of their time in the highest levels of the canopy and rarely venturing to the ground. To investigate terrestriality by Ateles and to illuminate the conditions under which spider monkeys venture to the ground, we analyzed ad libitum data from 5 study sites, covering 2 species and 5 subspecies. Three of the sites are in Central/North America: Barro Colorado Island (BCI), Panama (Ateles geoffroyi panamensis), Santa Rosa National Park, Costa Rica (A. g. frontatus), and Punta Laguna, Mexico (A. g. yucatanensis). The 2 remaining sites are …

Soil-Related Performance Variation And Distributions Of Tree Species In A Bornean Rain Forest, Sabrina E. Russo, Stuart J. Davies, David A. King, Sylvester Tan

School of Biological Sciences: Faculty Publications

1. Spatial distributions of tropical trees often correlate with environmental variation, suggesting that ecological sorting caused by niche differentiation may be important for maintaining species diversity.

2. Four soil types have been identified in a 52-ha forest dynamics plot in Bornean mixed dipterocarp forest (ranked by increasing fertility and moisture: sandy loam, loam, fine loam, and clay). The distributions of 73% of tree species in the plot are significantly aggregated on one of these soil types. We tested the hypothesis that variation in performance (growth and mortality) underlies these edaphically biased species distributions.

3. Annual growth and mortality rates over …

Insulin Signaling Is Necessary For Vitellogenesis In Drosophila Melanogaster Independent Of The Roles Of Juvenile Hormone And Ecdysteroids: Female Sterility Of The Chico1 Insulin Signaling Mutation Is Autonomous To The Ovary, David S. Richard, Robert Rybczynski, Thomas G. Wilson, Yue Wang, Marta L. Wayne, You Zhou, Linda Partridge, Lawrence G. Harshman

Lawrence G. Harshman Publications

It has been suggested that insulin signaling mutations of Drosophila melanogaster are sterile and long-lived because of juvenile hormone (JH) and ecdysteroid deficiency. However, female sterility of an insulin/IGF-like signaling mutant (chico¹) of D. melanogaster is not mediated by downstream systemic signaling in terms of major alterations in JH or ecdysteroid levels. chico¹ is a null mutation in the insulin substrate protein (CHICO) gene of D. melanogaster. Homozygous chico1 females are sterile and their oocytes do not mature beyond the last previtellogenic stage. Homozygous chico1 females exhibit approximately wild-type rates of JH biosynthesis, ovarian release …

Complex Signal Function: Developing A Framework Of Testable Hypotheses, Eileen Hebets, Daniel R. Papaj

Eileen Hebets Publications

The basic building blocks of communication are signals, assembled in various sequences and combinations, and used in virtually all inter- and intra-specific interactions. While signal evolution has long been a focus of study, there has been a recent resurgence of interest and research in the complexity of animal displays. Much past research on signal evolution has focused on sensory specialists, or on single signals in isolation, but many animal displays involve complex signaling, or the combination of more than one signal or related component, often serially and overlapping, frequently across multiple sensory modalities. Here, we build a framework of functional …

Abdominal Tuberculosis In Adolescents. Difficulties In Diagnosis., Mustafa Akcam, Reha Artan, Aygen Yilmaz, Hikmet Cig, Nazif H. Aksoy

Saudi Medical Journal

Since the nature of abdominal tuberculosis is mimicking a number of diseases, this may cause delayed diagnosis resulting in evident increased morbidity and mortality. Most of the time, serologic and bacteriologic tools are not enough. We report 3 adolescents with distinct presentations, one mimicking Crohn9s disease, one with hepatitis, and the last one with ascites. Terminal ileitis and mesenteric lymphadenitis were found in laparotomy of the first case mimicking Crohn disease. Granulomatous hepatitis was found in the liver biopsy of the second patient, and peritonitis was found by laparoscopy of the third patient. Tuberculosis could be diagnosed merely by histopathologic …

A Framework For Describing And Classifying Multicriteria Portfolio Selection Problems: An Object-Oriented Approach, Heinz Roland Weistroffer, Charles H. Smith

Journal of International Technology and Information Management

Many decisions require not a single solution alternative, but a set or portfolio of alternatives. For example, a business generally produces not a single product, but a portfolio of products, and a project is tackled not by a single individual, but by a team of individuals. Unfortunately, the portfolio selection problem has been largely neglected in the literature. Though many specific problem environments have been discussed using heuristic, ad hoc methods, no general methodology or theory has been developed. This paper proposes an object-oriented framework to provide a theoretical foundation for future research on the portfolio selection problem.

Effects Of Endogenous Steroid Hormone Levels On Annual Survival In Cliff Swallows, Charles R. Brown, Mary Bomberger Brown, Samrrah A. Raouf, Linda C. Smith, John C. Wingfield

School of Biological Sciences: Faculty Publications

The hormone corticosterone is an important part of animals’ response to environmental stress, modulating short-term adaptive changes in behavior and physiology. The hormone testosterone is also critical, especially for males, in regulating the expression of sexual behavior and parental care. These hormones can have costly consequences, however, and within populations individuals show variation in endogenous levels of both corticosterone and testosterone. We studied how annual survival varied as a function of natural levels of these hormones in colonially breeding Cliff swallows (Petrochelidon pyrrhonota) in southwestern Nebraska, USA, in 2000–2003. We sampled hormone levels of birds caught at colonies …
