Effects Of Infection Of The Protist Parasite, Dermomycoides Sp., In Dusky Gopher Frog Tadpoles, Jaime Smith

Master's Theses

Infections of the protist parasite, Dermomycoides sp. are thought to have caused several years of low recruitment in the dusky gopher frog (Rana sevosa) populations. I evaluated the effects of density of the infective zoospores, host developmental stage, and tadpoles' ability to acquire resistance to Dermomycoides sp. on dusky gopher frog tadpoles. Tadpoles were exposed to zoospore densities of 0, 250, 500, and 750 zoospores/µL at Gosner stage 25, and we found no significant differences among treatments in tadpole mortality. In evaluating susceptibility by development stage, I exposed R. sevosa to 50 zoospores/µL as eggs, embryos, hatchlings, and …

Pathology Findings And Correlation With Body Condition Index In Stranded Killer Whales (Orcinus Orca) In The Northeastern Pacific And Hawaii From 2004 To 2013, Stephen A. Raverty, Judy St. Leger, Dawn P. Noren, Kathy Burek Huntington, David S. Rotstein, Francis M.D. Gulland,, Deborah A. Duffield, Multiple Additional Authors

Biology Faculty Publications and Presentations

Understanding health and mortality in killer whales (Orcinus orca) is crucial for management and conservation actions. We reviewed pathology reports from 53 animals that stranded in the eastern Pacific Ocean and Hawaii between 2004 and 2013 and used data from 35 animals that stranded from 2001 to 2017 to assess association with morphometrics, blubber thickness, body condition and cause of death. Of the 53 cases, cause of death was determined for 22 (42%) and nine additional animals demonstrated findings of significant importance for population health. Causes of calf mortalities included infectious disease, nutritional, and congenital malformations. Mortalities in sub-adults were …

Hormonal Responses To Seasonal Thermal And Ecological Stressors In Japanese Macaques (Macaca Fuscata), Lilianne Nelson

Masters Theses

Relative to most primate species, Japanese macaques (Macaca fuscata) experience extreme seasonal variation in thermal and ecological stressors that can impact energetic demands. To cope with these environmental changes, levels of metabolic hormones, such as cortisol and triiodothyronine, fluctuate to facilitate energetic adjustments. While previous research in primates has investigated thermal and ecological stressors individually, a combined assessment of these stressors alongside hormone levels can provide a more holistic understanding of the relationship between a primate’s thermoregulation, energetic balance, and stress. The goals of this study were to determine the effects of season, temperature and ecological stress on …

The Impact Of Microbial Experience On The Murine Innate Immune Response, Cody Thomas Morrison

Masters Theses

The hygiene hypothesis predicts that certain environmental factors shape overall immune system function in animals and humans. While current specific pathogen free (SPF) mouse models are invaluable for studying the immune system, they have limitations for comparison with humans who have microbial exposures throughout their lifetimes. Several studies have shown that the composition of the immune system of SPF mice more closely resembles that of newborns, whereas the immune system from mice exposed to microbial pathogens more closely reflect adult immunity. In this study we have established a model using traditional SPF mice (“clean mice”) and SPF mice that were …

Drivers Of Decadal Vegetation Change In Northern Alaska, Jacob Allen Harris

Masters Theses

The Arctic is experiencing rapid climate change. This research documents vegetation change near Atqasuk and Utqiaġvik, Alaska. At each location, 30 plots distributed in a matrix across the landscape, were sampled annually from 2010 to 2019 using a point frame. For every encounter we recorded the height and classified it into eight broad functional groups (deciduous shrubs, evergreen shrubs, forbs, graminoids, bryophytes, lichens, litter and standing dead vegetation); for vascular plants we also identified the species. We found a consistent increase in plant stature and cover over time which was dramatic at Atqasuk. Graminoid cover and height increased at both …

“9/11 And The Collapse Of The American Dream: Imbolo Mbue’S Behold The Dreamers”, Elizabeth Toohey

Publications and Research

Behold the Dreamers follows a Cameroonian couple who, as newcomers to America, harbor dreams of success unavailable to them back home. Undocumented immigration, the widening gulf between rich and poor, and the thinly veiled racism of an avowedly "post-racial" culture converge in this new generation of immigrants' painful encounter with the American dream. I consider the ways Mbue's novel shares themes with a "second wave" of post- 9/11 literature—first, in centering the disillusionment of a protagonist aspiring to the American dream; next, in its representation of New York as a space haunted by 9/11, but also of resistance to the …

Laboratories Of Exclusion: Medicaid, Federalism & Immigrants, Medha D. Makhlouf

Faculty Scholarly Works

Medicaid’s cooperative federalism structure gives states significant discretion to include or exclude various categories of immigrants. This has created extreme geographic variability in immigrants’ access to health coverage. This Article describes federalism’s role in influencing state policies on immigrant eligibility for Medicaid and its implications for national health policy. Although there are disagreements over the extent to which public funds should be used to subsidize immigrant health coverage, this Article reveals that decentralized policymaking on immigrant access to Medicaid has weakened national health policy. It has failed to incentivize the type of state policy experimentation and replication that justifies federalism …

This study will advance the understanding of factors that may impact the acceptance of BC at the management level. Research Questions 1. Can behavioral intention (BI) to adopt BC tools be predicted by using an independent variable representing Perceived Ease-Of-Use (PEOU)? 2. Can behavioral intention (BI) to adopt BC tools be predicted by using an independent variable representing Perceived Usefulness …

The Regulation Of Commercial Speech: Can Alternative Meat Companies Have Their Beef And Speak It Too?, Eryn Terry

Vanderbilt Journal of Entertainment & Technology Law

Would you eat a hamburger that was made in a petri dish? Consumers may have this option soon as laboratory-grown meat begins to hit supermarket shelves. Laboratory-grown meat is made from animal stem cells that eventually transform into primitive fibers and tissue within the confines of a petri dish. Although a lot remains unknown about laboratory-grown meat, consumers can think of it as meat production without the farm. How might consumers react to meat labels indicating that their products were made in a petri dish? Laboratory-grown meat companies have yet to find out, as some states have passed laws that …

The Sick Ones., Christian Loriel Lucas

Electronic Theses and Dissertations

This thesis consists of a collection of linked short stories, connected at the intersections of medicine, public health, race, gender, and socioeconomics. The Sick Ones was completed during a time of social unrest and the emergence of the Covid-19 virus. Inspired by medicine’s history of exploiting sick, poor, and racialized bodies, The Sick Ones explores the treatment of illness and societal woes in a near-speculative future. Each story is plot-driven, but complimented by a protagonist who keeps the narrative grounded, as they attempt to survive unprecedented circumstances. Some of the protagonists are complicit in their own medical exploitations, while others …

The Green House (GH) model is a type of culture change which focuses on deinstitutionalizing traditional NHs to provide better quality of care and quality of life to NH residents. The two main objectives of this study are: to describe the GH model and its elements and to identify which GH elements impact the quality of care. This study also seeks to identify organizational theories used in the GH analysis. The next objective is to analyze the impact of the GH …

Evaluating The Effects Of Pcbs In Non-Alcoholic Fatty Liver Disease & Diabetes And The Role Of Ahr In Regulating The Hepatic Proteome And Lipid Metabolism., Jian Jin

Electronic Theses and Dissertations

Polychlorinated biphenyls (PCBs) are persistent organic pollutants associated with non-alcoholic fatty liver disease (NAFLD) and diabetes. Based on their ability to activate the aryl hydrocarbon receptor (AhR), PCBs are subdivided into two classes: dioxin-like (DL) and non- dioxin-like (NDL) PCBs. This study not only evaluated the chronic effect of DL PCBs (PCB126), NDL PCBs (Aroclor1260 mainly contains NDL), and the DL/NDL PCB mixture (PCB126/Aroclor1260 mixture) on liver, but also explored the acute hepatic effects of DL PCB and potential mechanisms in NAFLD and the role of AhR in regulating hepatic proteome and lipid metabolism, and whether the process independent of …

Development Of A Pediatric Cardiac Assist Maglev Pump For Use With A Universal Driver System., Landon Heath Tompkins

Electronic Theses and Dissertations

Heart failure (HF) remains the leading cause of death, affecting 26 million adults worldwide and 6.5 million adults in the United States. Pediatric HF patients have been a historically underserved population with few options for mechanical circulatory support (MCS) therapy, a leading treatment as an alternative to heart transplantation. To address this clinical need, the Inspired Universal MagLev System is being developed; a low cost, universal magnetically levitated extracorporeal MCS system with interchangeable single-use pumps that will ultimately provide adult and pediatric patients ventricular and respiratory assist therapies. The Inspired Pediatric VAD is the first single-use pump application for this …

The Effects Of Whole Life, Low Dose Cadmium Exposure On High Fat Diet-Induced Nonalcoholic Fatty Liver Disease And The Role Of Zinc., Jamie Lynn Young

Electronic Theses and Dissertations

Nonalcoholic fatty liver disease (NAFLD) is a major global public health concern affecting more than 25% of the world’s population. Although obesity is a major risk factor for NAFLD, it cannot account for many cases, indicating the importance of other factors such as sex and environmental exposures. Cadmium exposure is implicated in the development of NAFLD; however, the influence of early-life, in utero cadmium exposure on the development of diet-induced NAFLD is poorly understood. Therefore, we developed an in vivo, multiple-hit model to study the effect of whole-life, low-dose cadmium exposure on high fat diet (HFD)-induced NAFLD. Additionally, we …

On The Straight And Narrow: How Cultural Beliefs About Sex/Gender Manifest In College Biology Learning Environments., Katherine Ray Kng

Electronic Theses and Dissertations

This dissertation focused on the ways that social beliefs about sex/gender and sexuality manifest in biology classrooms. Especially for health science students, classes include topics like sex, sexuality, sexual behaviors, or sex determination that forms the foundation of their understanding of human forms and behaviors. If the information they receive does not include the LGBTQIA+ community, their education will fail to adequately prepare them for the reality of healthcare practice where they will be expected to treat all patients with dignity and respect. There are three chapters in this dissertation. In chapter one, I asked what beliefs about and conceptions …

Hydration, Shrinkage, Cracking, And Mechanical Properties Of Cementitious Materials With Lignocellulosic Biomass Wastes., Aofei Guo

Electronic Theses and Dissertations

The disposal of lignocellulosic biomass wastes imposes a huge economic and environmental burden on this society. Recycling lignocellulosic biomass wastes and applying them to cementitious materials provides a sustainable and value-added way for both agriculture and concrete industries. To comprehensively identify the effect of lignocellulosic biomass wastes at different scales on cementitious materials, the hydration, shrinkage, cracking, and mechanical properties of cementitious materials with lignocellulosic biomass wastes were studied. Given the three different forms (powders, chips, and fibers) of lignocellulosic biomass wastes in this study, the research was implemented in three stages. In the first stage, hemp powders were collected …

The Influence Of Proximal And Distal Familial Factors On Preschool Children's Inhibitory Control And Social Emotional Skills, Amy Encinger

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Children in the United States experience higher rates of poverty than any other age group, including elderly adults and the poverty rate of young children (0-5 years) is considerably higher than that of older children (Proctor et al., 2016). There is an extensive body of research examining familial socioeconomic status (SES) and the influence on the skills and behaviors of young children; however, common key indicators of family SES may not fully depict the ways in which children living in poverty/low-income homes are influenced by economic disadvantage. The focus of the current study is to explore the ways in which …

Assessment Of Grain Safety In Developing Nations, Jose R. Mendoza

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Grains are the most widely consumed foods worldwide, with maize (Zea mays) being frequently consumed in developing countries where it feeds approximately 900 million people under the poverty line of 2 USD per day. While grain handling practices are acceptable in most developed nations, many developing nations still face challenges such as inadequate field management, drying, and storage. Faulty grain handling along with unavoidably humid climates result in recurrent fungal growth and spoilage, which compromises both the end-quality and safety of the harvest. This becomes particularly problematic where there is little awareness about health risks associated with poor …

Adding The Third Dimension To Studies Of Parallel Evolution Of Morphology And Function: An Exploration Based On Parapatric Lake-Stream Stickleback, Grant E. Haines, Yoel E. Stuart, Dieta Hanson, Tania Tasneem, Daniel I. Bolnick, Hans Ce Larsson, Andrew P. Hendry

Biology: Faculty Publications and Other Works

Recent methodological advances have led to a rapid expansion of evolutionary studies employing three-dimensional landmark-based geometric morphometrics (GM). GM methods generally enable researchers to capture and compare complex shape phenotypes, and to quantify their relationship to environmental gradients. However, some recent studies have shown that the common, inexpensive, and relatively rapid two-dimensional GM methods can distort important information and produce misleading results because they cannot capture variation in the depth (Z) dimension. We use micro-CT scanned threespine stickleback (Gasterosteus aculeatus Linnaeus, 1758) from six parapatric lake-stream populations on Vancouver Island, British Columbia, to test whether the loss …

《讀書聲》與清初社群的界限, Ariel Fox

嶺南學報 Lingnan Journal of Chinese Studies

本文透過傳奇《讀書聲》中出現的奇異生物，探索了帝國晚期的中國對於非人他者的想像。全劇行至中段，元初書生宋儒發現自己被抛棄在一座遥遠的荒島上。在那裏，他被一隻人熊救起並與之結爲伴侣，這是一隻勇猛卻又充滿善意的類熊生物。儘管兩者的結合時日不長，但是藉由婚姻，邊緣化角色被置於中心位置（既是故事的、又是帝國的中心），這樣的情節在全劇爲數不多，因而具有重要意義：此外，待到結局之時，書生與船夫之女和蒙古官員之女雙雙成婚。然而，當這樣的雙重婚姻爲有效跨越文人與商人、漢人與蠻夷之間的差異提供了可能，人熊的悲劇命運卻又消弭了任何跨越人獸界綫的機會。換言之，随著商人和蒙古人成爲新的社會群體的一部分，人熊卻標誌着一條必需的界限。劇中，正是這條界限使得社會與民族的他者擺脱了低賤與野蠻的標籤。與此同時，新社群對於人熊的排斥也並非無憂；通過顛覆傳奇普遍對完整性的强調，《讀書聲》戲劇性地展示了清初秩序重建所必經的分裂與排斥。

This article explores the late imperial imagination of the nonhuman other by way of a curious creature that appears in the southern drama Dushu sheng. Midway through the play, set in the early years of the Yuan dynasty, the young literatus protagonist is abandoned on a remote island, where he is rescued by a renxiong, a fierce yet empathetic bear-like creature that takes him as its mate. Though short-lived, their union is one of several in the play in which marginal characters are brought into the (narrative and imperial) center through marriage: by the end of the …

Effect Of Sound Source Location And Spatial Hearing On The Vestibulo-Ocular Reflex (Vor), Mary Easterday

Theses and Dissertations (ETD)

Accurate measurement of the vestibulo-ocular reflex (VOR) is imperative in differential diagnosis of vestibular disorders and balance function. However, the assessment protocol faces a number of limitations, including the need to control for extra- vestibular sensory factors such as hearing. Previous research has shown that the use of an auditory stimulus can have a significant effect on functional measures of balance, and many have contributed effects to be the result of spatial hearing. However, no studies have directly assessed the effect of speaker location on the VOR nor investigated correlations of functional spatial hearing with the VOR. Therefore, the aims …

Empathy And Community In The Age Of Refugees: Petzold’S Radical Translation Of Seghers’ Transit, Margarete Landwehr

Languages & Cultures Faculty Publications

Petzold’s film constitutes a radical translation of Seghers’ novel by transforming her tale of political refugees in Vichy France into an existential allegory depicting the fluidity of identities and relationships in a globalized world. The transitory existence of Petzold’s war refugee serves as an extreme example of the instability of modern life, which allows spectators to identify and empathize with migrants’ unpredictable journeys. Moreover, the director conveys the universality of his protagonist’s story by portraying him as an Everyman bereft of distinctive personality traits, by intermingling the past (Seghers’ plot) with the present (contemporary settings), and by situating his experiences …

Analysis Of The Population Dynamics Of Placida Dendritica And Codium Fragile In The Gulf Of Maine And A Theoretical Discussion Of Invasive Species, Seth Goodnight

Doctoral Dissertations

This dissertation examines several aspects of the biology and ecology of Codium fragile and Placida dendritica in the Gulf of Maine. Scientific interest in nonindigenous species was examined to determine if any patterns were evident that might indicate a change in the status of an invasive species. Interest in C. fragile had waned in recent years, the timing of which coincides with the decreased ecological dominance and apparent naturalization of the alga. Laboratory and field studies were combined to quantify the dynamics in the population of C. fragile and in the recruitment dynamics of P. dendritica. Results of laboratory research …

Bacterial Genome And Population Dynamics With Implications For Public Health, Cooper John Park

Doctoral Dissertations

Bacterial populations are extraordinarily heterogeneous. Despite growing clonally, these populations are often composed of multiple lineages distinguished by both phenotypic and genetic differences that are caused by both allelic and whole gene variation. Such genomic mosaicism and within-species variation can significantly impact a species’ response to selective pressures from antibiotic use, vaccination, immune responses and host environment. One important process that contributes to this phenomenon is recombination, the exchange of very similar DNA sequences between strains which can result to either the addition or replacement of homologous genes. Current models of microbial recombination incorporate the null expectation that recombination is …
