Arachidonic Acid Reverses The Pyriproxyfen And Ibuprofen Induced Toxicity In Daphnia Magna, Gautam Kumar Ginjupalli

All Dissertations

Healthy reproduction and neonatal sex ratios of Daphnia are crucial to the health of the aquatic ecosystems in which Daphnia play principal roles in trophic transfer of nutrients. Combinations of environmental factors such as availability and quality of diet, overcrowding, hypoxia, reduced photoperiods and fall in ambient temperatures perturb normal parthenogeneic reproduction and induce sexual reproduction through male production. Male production provides a mechanism for overcoming specific stressors such as overcrowding and overwinter pond desiccation. However, it also induces a decrease in the Daphnia population that could have adverse implications on the pond ecosystem that depend on Daphnia . Interestingly, …

Ecology And Impacts Of Coyotes (Canis Latrans) In The Southeastern United States, Cady Etheredge

All Dissertations

Recent coyote (Canis latrans ) colonization of the southeastern United States has prompted speculation on the top-down effects of a new top predator on systems which have gone without a strong predator presence since the extirpation of the red wolf (Canis rufus ). This dissertation reports on the results of a series of investigations of the potential impact of coyotes on raccoons (Procyon lotor ) and other management issues related to coyotes in the Southeast. Chapters 1-3 present indirect field tests of the Mesopredator Release Hypothesis. Chapter 4 presents an overview of the current knowledge of the …

Biological Scaffolds For Peripheral Vascular Surgery, George Fercana

All Dissertations

The gold standards for small diameter peripheral vascular graft replacement are autologous arteries or veins; however, one-third of patients lack such vessels due to previous vessel harvesting or advanced vascular disease. A promising approach for patients in this category is tissue engineering with off-the-shelf biological vascular grafts. Three small diameter acellular scaffolds were developed and evaluated as vascular grafts. Porcine renal arteries (2-3 mm diameter, 20 mm length) were decellularized by immersion and stabilized with penta-galloyl glucose (PGG) with and without subsequent heparinization via carbodiimide chemistry. Bovine mammary (4-6 mm ID, 250 mm length) and femoral arteries (6-8 mm ID, …

The Effects Of Yoga Participation On Symptoms Associated With Menopause: A Mixed Methods Study, Brandi Crowe

All Dissertations

During midlife, it is expected that women will progress towards the biological state of menopause; the permanent condition of infertility due to alterations or diminution of reproductive hormones. Typically lasting 5-10 years, the menopausal transition is associated with symptoms including hot flashes, night sweats, interrupted sleep, anxiety, forgetfulness, and inconsistent mood. As these symptoms often hinder a women's successful functioning in everyday life, hormone therapy is commonly prescribed as a means for diminishing symptoms. However, many women are seeking alternative/complementary treatments that can assist in managing menopausal symptoms due to the detrimental health-risks associated with the use of conventional therapies. …

Investigation Of The Life History And Lipid Content Consequences Of Reduced Abundance Of Delta-9 Desaturases In Drosophila Melanogaster, Li Ko

School of Biological Sciences: Dissertations, Theses, and Student Research

Monounsaturated fatty acids (MUFAs) are essential components in all organisms, and the key enzymes that catalyze the production of MUFA are delta-9 desaturases. These enzymes are ER bound and introduce the first double bonds in saturated fatty acids. To investigate the role that delta-9 desaturases play in Drosophila life history and development we performed a series of studies using the RNAi method. Longevity results showed die-off peaks of the knocked-down (KD) flies at day 45. Fecundity study showed decreases in both egg productions and viability of these eggs. Development difficulties were observed in both regular diet and low fat diet. …

Trade-Offs In Male Lek Behavior, Sarah A. Cowles

School of Biological Sciences: Dissertations, Theses, and Student Research

In lek mating systems, males aggregate together and perform courtship displays to visiting females. However, display may be energetically expensive and reduce the time available for foraging. These costs in turn could lower energy reserves, which could decrease survival. I examined trade-offs in male lek behavior using two methods: 1) I conducted an empirical study of how sharp-tailed grouse (Tympanuchus phasianellus) males allocate time between courtship display (“dancing”), agonism, foraging, and inactivity in relation to female numbers both within and across days. I also measured head turning rates during these same behaviors as a proxy for visual attentiveness …

The Roles Of Phenotypic Plasticity And Genotypic Specialization In High Altitude Adaptation, Danielle M. Tufts

School of Biological Sciences: Dissertations, Theses, and Student Research

In vertebrates living at high altitude, arterial hypoxemia may be ameliorated by reversible changes in the oxygen-carrying capacity of the blood (regulated by erythropoiesis) and/or changes in blood–oxygen affinity (regulated by allosteric effectors of hemoglobin function). These hematological traits often differ between taxa that are native to different elevational zones, but it is often unknown whether the observed physiological differences reflect fixed, genetically based differences or environmentally induced acclimatization responses (phenotypic plasticity). Here, we report measurements of hematological traits related to blood–O₂ transport in populations of deer mice (Peromyscus maniculatus) that are native to high- and low-altitude …

An Efficient Two Sample Capture-Recapture Model With High Recaptures, Danjuma Jibasen, Yusuf J. Adams

CBN Journal of Applied Statistics (JAS)

This paper proposed an efficient two sample capture-recapture model (Ma) with high recaptures and compared it with the existing models like the model of no factor effect (Mo), behavioral response model (Mb) and the Petersen model (Ms), using simulated data. We found that the Petersen model provides a better estimate of the population size when the observations follow a hypergeometric distribution and the population is overestimated when recapture is high. It was also found that the proposed model provides a better estimator of the population size than the existing ones when the recapture is high. This model is particularly useful …

The Fiduciary Doctrine As A New Pathway: An Alternative Approach To Analysing Native Customary Rights In Sarawak, Hang Wu Tang

Research Collection Yong Pung How School Of Law

This paper explores the use of the fiduciary doctrine whereby the state is conceived as a fiduciary vis-à-vis her native peoples and attendant equitable remedies are made available for the native customary rights over land in Sarawak. Thus far, most challenges to extinguishment of native customary rights in Sarawak have proceeded on constitutional grounds, with little success. This article draws on the jurisprudence of fiduciary law in other parts of the Commonwealth and argues that this is a viable alternative cause of action against the state.

The Resilience Of Property, Lynda L. Butler

Faculty Publications

Resilience is essential to the ability of property to face transforming social and environmental change. For centuries, property has responded to such change through a dialectical process that identifies emerging disciplinary perspectives and debates conflicting values and norms. This dialectic promotes the resilience of property, allowing it to adapt to changing conditions and needs. Today the mainstream economic theory dominating common law property is progressively being intertwined with constitutionally protected property, undermining its long-term resilience. The coupling of the economic vision of ordinary property with constitutional property embeds the assumptions, choices, and values of the economic theory into both realms …

Hierarchically Variable Deference To Agency Interpretations, Aaron-Andrew P. Bruhl

Faculty Publications

When courts review agency action, they typically accord agency decisions a degree of deference. As many courts and commentators have recognized, the law in this area is complicated because it features numerous standards of review, including several distinct regimes for evaluating agencies’ legal interpretations. There is, however, at least one important respect in which uniformity rather than variety prevails: the applicable standards of review do not vary depending on which court is reviewing the agency. Whichever standard governs a particular case—Chevron, Skidmore, or something else—all courts in the judicial hierarchy are supposed to apply that same standard.

This Article proposes …

Evaluating Flexibility In International Patent Law, Sarah R. Wasserman Rajec

Faculty Publications

Global patent law has raced toward harmonization over the past decades. Countries with vastly different industries, values, and levels of development now offer robust patent rights with similar contours through membership in the World Trade Organization and consequent adoption of the Agreement on Trade-Related Aspects of Intellectual Property Rights (“TRIPS”). However, patent law is still far from harmonized among countries or static within countries. Jurisdictions tailor their patent laws to accommodate differences between industries, unforeseen inefficiencies, and diverse views of the costs and benefits associated with offering patent rights to stimulate innovation. Prior scholarly work consists of either doctrinal analyses …

A Northward Range Extension Of The Hispid Cotton Rat (Sigmodon Hispidus) In Missouri, Cody W. Thompson, Elmer J. Finck

The Prairie Naturalist

The hispid cotton rat (Sigmodon hispidus) is a widely distributed rodent with a geographic range extending from north-central Mexico to southern Nebraska and central Virginia and from southeastern Arizona east to Florida (Carleton et al. 1999, Peppers and Bradley 2000, Wilson and Reeder 2005) with isolated populations in Arizona (Bradley et al. 2012) and California (Clark 1972). Range expansions for the species have been well documented (Clark 1972, Farney 1975, Benedict et al. 2000, Wright et al. 2010, Wills et al. 2011). The majority of these range expansions have occurred across the Central Plains during the 20th century …

Evaluation Of Three Nest Searching Methods For Ring-Necked Pheasant, Jeffery W. Stackhouse, Kevin K. Sedivec, Benjamin A. Geaumont

The Prairie Naturalist

Ring-necked pheasant (Phasianus colchicus) are a highly sought after game bird and as such, much research has been conducted regarding their ecology (Warner 1981, Trautman 1982, Johnson and Knue 1989). Perhaps the most investigated aspect of pheasant ecology is the species’ reproductive season (e.g. Linder et al. 1960, Dumke and Pils 1979, Leif 1994) with many studies focusing on nesting habitat (Baskett 1947, Clark et al. 1999). Results from previous research have acknowledged the difficulty associated with locating pheasant nests in their preferred cover types (Hanson 1970, Evrard 2000). Studies of pheasant nesting ecology have been based on …

Salamander Colonization Of Chase Lake, Stutsman County, North Dakota, David M. Mushet, Kyle I. Mclean, Craig A. Stockwell

The Prairie Naturalist

Salt concentrations in lakes are dynamic. In the western United States, water diversions have caused significant declines in lake levels resulting in increased salinity, placing many aquatic species at risk (Galat and Robinson 1983, Beutel et al. 2001). Severe droughts can have similar effects on salt concentrations and aquatic communities (Swanson et al. 2003). Conversely, large inputs of water can dilute salt concentrations and contribute to community shifts (Euliss et al. 2004).

Chase Lake is a large, shallow, alkaline lake in east-central North Dakota most famously known for supporting one of the largest breeding colonies of the American white pelican …

Associations Between Iron Concentration And Productivity In Montane Streams Of The Black Hills, South Dakota, Cari-Ann Hayer, Benjamin M. Holocmb, Steven R. Chipps

The Prairie Naturalist

Iron is an important micronutrient found in aquatic systems that can influence nutrient availability (e.g. phosphorus) and primary productivity. In streams, high iron concentrations often are associated with low pH as a result of acid mine drainage, which is known to affect fish and invertebrate communities. Streams in the Black Hills of South Dakota are generally circumneutral in pH, yet select streams exhibit high iron concentrations associated with natural iron deposits. In this study, we examined relationships among iron concentration, periphyton biomass, macroinvertebrate abundance, and fish assemblages in four Black Hills streams. The stream with the highest iron concentration (~5 …

Relationships Among Walleye Mercury, Selenium, Stable Isotopes, Size And Age, Mark J. Fincel, Robert P. Hanten, Shannon Minerich

The Prairie Naturalist

Bioaccumulation of mercury is well-documented in aquatic ecosystems and occurs as mercury is accumulated and passed up food chains (Kidd et al. 1995, Atwell et al. 1998, Downs et al. 1998). Trophic level correlations have been widely reported for mercury (Snodgrass et al. 2000) and other metals (Barron 1995). Generally, within a system, carnivores have the highest mercury loadings, omnivores intermediate and herbivores the lowest (Phillips et al. 1980). However, little research has focused on the differences in mercury bioaccumulation for a single species that ranges across multiple trophic levels (Burger et al. 2001).

Stable isotope analysis has expanded the …

A New Species Of Euscorpius From Tinos Island, Greece (Scorpiones: Euscorpiidae), Victor Fet, Michael E. Soleglad, Aristeidis Parmakelis, Panayiota Kotsakiozi, Iasmi Stathi

Biological Sciences Faculty Research

The scorpion genus Euscorpius has been insufficiently studied on the Aegean Islands of Greece. We describe a new species from the Western Cyclades, E. kritscheri sp. n., from Tinos Island. The species-level status of this form is confirmed by a phylogenetic study based on multiple DNA markers. In addition, a population from nearby Andros Island is characterized as E. cf. kritscheri, which could be potentially a separate species.

Eternal Recurrence In A Neo-Kantian Context, Michael S. Green

Faculty Publications

In this essay, I argue that someone who adopted a falsificationism of the sort that I have attributed to Nietzsche would be attracted to the doctrine of eternal recurrence. For Nietzsche, to think the becoming revealed through the senses means falsifying it through being. But the eternal recurrence offers the possibility of thinking becoming without falsification. I then argue that someone who held Nietzsche’s falsificationism would see in human agency a conflict between being and becoming similar to that in empirical judgment. In the light of this conflict only the eternal recurrence would offer the possibility of truly affirming life. …

Development Of In Vitro Chylomicron Assay Using Caco-2 Cells, Yuxi Sun

Electronic Theses and Dissertations

Dietary fats are mainly transported by the intestine in lipoproteins: chylomicrons (CMs) and very low density lipoproteins (VLDLs). Unfortunately, studies of the intestinal absorption of dietary fat have been hampered by the lack of an adequate in vitro model system. As an in vitro model Caco-2 cells are able to secrete lipoproteins. We investigated the possible factors that may affect the secretion of CMs through the ultracentrifugation technique. The dose-dependent effects of oleic acid, mono-olein, egg lecithin, collagen matrix, and the effect of cell differentiation on CM secretion were then tested. We found that oleic acid, lecithin, and cell differentiation …

Fire On The Prisoners: An Autoethnographic Study Of Ethics In Historical Storytelling, A. Trae Mcmaken

Electronic Theses and Dissertations

During field experience as a storyteller constructing a performance based on the Battle of Kings Mountain on behalf of the Overmountain Victory Trail Association and the Overmountain Victory National Historic Trail, I encountered ethical and philosophical dilemmas. This challenge centered on ethical and spiritual convictions that put me in potential conflict with the task of creating a performance about war. This experience forms the basis of an autoethnographic approach to the art form, revealing the critical role played by personal ethics and a functioning engagement with historiography and narrative theory in producing effective performance stories. Historical performance storytelling has little …

Soros’S Reflexivity Concept In A Complex World: Cauchy Distributions, Rational Expectations, And Rational Addiction, John B. Davis

Economics Faculty Research and Publications

George Soros makes an important analytical contribution to understanding the concept of reflexivity in social science by explaining reflexivity in terms of how his cognitive and manipulative causal functions are connected to one another by a pair of feedback loops (Soros, 2013). Fallibility, reflexivity and the human uncertainty principle. Here I put aside the issue of how the natural sciences and social sciences are related, an issue he discusses, and focus on how his thinking applies in economics. I argue that standard economics assumes a ‘classical’ view of the world in which knowledge and action are independent, but that we …

Redefining Social Welfare: Connections Across Species, Christina Risley-Curtiss

The Journal of Sociology & Social Welfare

A growing body of research supports the notion that human well-being is inextricably connected to the welfare of other animals. Social scientists are exploring these connections in research in social work and various subfields of sociology, including those focusing on the environment, deviance, the family, health, social inequality, and religion, as well as the emerging field of animals and society. This special issue taps researchers and theorists from several countries in a wide range of subfields in order to capture the breadth of the connections among species that affect all aspects of human well-being. This is a double issue, as …

Human Consequences Of Animal Exploitation: Needs For Redefining Social Welfare, Atsuko Matsuoka, John Sorenson

The Journal of Sociology & Social Welfare

This paper addresses an area which has not been given serious consideration in social welfare and social work literature, the instrumental use of nonhuman animals, in particular as food, and argues that the welfare of humans and other animals are intertwined. The paper examines the consequences of animal exploitation for humans in terms of health, well-being, environmental damage, and exploitation of vulnerable human groups. The paper concludes that a necessary redefinition of social welfare entails attention to these issues and the recognition that other animals have inherent value and their rights must be respected.

Relational Ecology: A Theoretical Framework For Understanding The Human-Animal Bond, Jennifer M. Putney

The Journal of Sociology & Social Welfare

This qualitative study investigated the perceived impact of companion animals on the psychological well-being of lesbian women over age 65. Twelve women, ranging in age from 65-80, were interviewed with a semi-structured interview guide. Four thematic findings are highlighted: love and attachment, animals in transitional spaces, challenges and rewards of caregiving, and preparation for death. The author offers the term "relational ecology" to explain how animals contribute to well-being. This integrates the growth task model of human development, object relations theory, liminality, and deep ecology.
