Physiological Changes Associated With Pregnant Or Nonpregnant Mares Grazing Pastures Of Orchardgrass-Bluegrass, Kentucky 31 Tall Fescue Infected With Epichloë Coenophiala, Or Kyfa9821 Tall Fescue Infected With The Novel Endophyte Ar584, Victoria A. Taylor

Theses and Dissertations--Veterinary Science

Kentucky 31 tall fescue (KY31) infected with the common toxic endophyte strains of Epichloё coenophiala produces toxic alkaloids that improve plant vigor, but cause numerous adverse effects in grazing animals. Researchers developed a variety of KY31 containing an alternative strain of E. coenophiala, termed novel endophyte (NE). Adverse health effects in mares have not been evaluated.

Experiments in this thesis tested the hypothesis that the NE pasture does not cause adverse effects typically associated with KY31. Specific aims were to: 1) compare forage ergovaline concentrations between KY31 vs NE pastures; 2) evaluate palmar artery diameters in mares grazing KY31, …

Initial Understory Response To Gap-Based Regeneration Methods For Mature Upland Oak Forests, Clinton Patrick Patterson

Theses and Dissertations--Forestry and Natural Resources

Problems with oak regeneration, and concerns by environmental and conservation organizations, are driving interest in longer rotations and in reproduction methods that retain the overstory for an extended time period. Clearcutting and shelterwood regeneration methods are providing mixed results for oak seedling development and recruitment due to the increased abundance of shade tolerant midstory species. The irregular group shelterwood (Femelschlag) system has been used in Central Europe to address these issues, and may provide the basis for a gap-based system in the Central Hardwood Forest Region. This study examines the two-year effects of a gap-based regeneration method featuring …

Altitude- And Sex-Specific Variation In Roosting Ecology And Thermoregulation Of Myotis Lucifugus In Yellowstone National Park, Alexandra C. Slusher

Theses and Dissertations--Forestry and Natural Resources

Fifty-nine female and six male little brown myotis (Myotis lucifugus) were radio-tagged during the summers of 2012, 2013, 2014, and 2015 in Yellowstone National Park. The grand models for daily maximum skin temperature (F_98,154 = 1.55, P = 0.007), daily minimum skin temperature (F_98,154 = 1.33, P = 0.05), and daily variation in skin temperature (F_98,154 = 1.56, P = 0.006) were significant across roost type and reproductive condition class for adult females. Roosts were classified into Types A (warmest roosts), B (roosts with largest daily temperature variance), and C (stable and cool roosts) depending …

Establishment Of Serological Reference Ranges For Elk In Kentucky And Effects Of Quarantine And Translocation On Elk, Aaron M. Hildreth

Theses and Dissertations--Forestry and Natural Resources

Establishing blood serum profiles is important for understanding animal disease ecology and nutrition, the effects of capture and immobilization, and general physiological variation among individuals and populations. Elk (Cervus elaphus nelsoni) have been successfully translocated to several states for reintroduction or population augmentation, including most recently in Kentucky, where over the course of three years (2011-13) wild elk were captured, temporarily quarantined, and subsequently moved to Missouri and Virginia to establish populations in those states. I used this opportunity to collect a variety of biological samples, including blood from which I present and compare serological profiles for a …

Evolution Of Equine Arteritis Virus During Persistent Infection In The Reproductive Tract Of The Stallion And The Male Donkey, Bora Nam

Theses and Dissertations--Veterinary Science

Equine arteritis virus (EAV) establishes persistent infection in the stallion reproductive tract, and the carrier stallion continues to shed virus in semen for weeks to years or lifelong. The objective of this study was to elucidate the intra-host evolution of EAV during persistent infection in stallions. Seven EAV seronegative stallions were experimentally infected with EAV KY84 strain and followed for 726 days post-infection, and sequential clinical samples including semen were collected for virus isolation and next-generation sequencing (NGS). In addition, archived sequential semen samples from two stallions that were naturally infected with EAV KY84 for a long-period (up to 10 …

Survival And Cause-Specific Mortality Of A Southeastern Kentucky Deer Population, Caleb Anderson Haymes

Theses and Dissertations--Forestry and Natural Resources

White-tailed deer are one of the most sought after game species in Kentucky. While much of the Commonwealth boasts high deer populations, those in southeast Kentucky are viewed as relatively low compared to other regions, even after a decade of restrictive doe harvest and multiple years of population supplementation via translocation. We studied survival and cause specific mortality of a local population of deer near the Redbird District of the Daniel Boone National Forest in Clay and Leslie County, Kentucky from January 2014 - January 2017. We estimated female annual survival at 0.89 (CI: 0.88-0.87), with an overall 3-year survival …

The Xenobiotic Transcription Factor Cap N Collar C Regulates Expression Of Multiple Insecticide Resistant Genes, Megha Kalsi

Theses and Dissertations--Entomology

Insecticide resistance is a global problem. Insecticide resistance management is very important, considering the time, effort, and cost of discovering and developing a new insecticide. There are diverse resistance mechanisms, but enhanced detoxification through overexpression of cytochrome P450s and target site insensitivity through mutation in insecticide binding site are the two most common mechanisms. The xenobiotic detoxification is divided into three successive phases (I, II and III), which ensures the metabolism and excretion of the detrimental toxins. Each phase comprises of a specific group of metabolizing enzymes such as P450s (phase I), GSTs (phase II) and ABC transporters (phase III). …

Exploring Predator-Prey Interactions In Agroecosystems Through Molecular Gut-Content Analysis, Kacie J. Athey

Theses and Dissertations--Entomology

Generalist predators can contribute to vital ecosystem services by potentially inducing trophic cascades as natural enemies of pests in agroecosystems. As the human population of the world gets larger, we need to produce more food on ever-smaller swaths of available land relying on ecosystem services, in the form of pest control, that may contribute to agricultural sustainability. Teasing apart the exact trophic linkages between predators and prey is a vital first step and essential to uncovering which predators are inducing trophic cascades and should be enhanced through conservation biological control.

Combined with ecological experimentation, the main tool used throughout my …

Evaluation Of Pyriproxyfen Applied In Barrier Sprays For Mosquito Suppression, Andrea Glenn Skiles

Theses and Dissertations--Entomology

Despite advances in mosquito management, mosquito-borne disease in the United States is still of relevant public health concern and vector control is a top priority in preventing transmission of pathogens. Insecticide barrier sprays have become a common tool for suppression of mosquitoes in single-homeowner backyards. The application of the synthetic pyrethroid, lambda-cyhalothrin to perimeter vegetation with a backpack sprayer has been shown to significantly suppress mosquito levels for around 6 weeks. In an attempt to lengthen the effective duration of treatment, the IGR, pyriproxyfen, was added to a backpack mist blower with lambda-cyhalothrin, as adult mosquitoes exposed to pyriproxyfen have …

Extended Family Relationships: How They Impact The Mental Health Of Young Adults, Kayla Jansen

Theses and Dissertations--Family Sciences

This study bridges the gap in literature about the impact of extended family relationships on young adult depression and self-esteem. A sample of 304 undergraduate students between the ages of 18 and 21 at the University of Kentucky was recruited to complete an online survey about their immediate and extended family relationships and their mental health. The largest predictor of self-esteem and depression in early young adults is perceived social support from the family of origin, which is also moderately correlated with perceived support from extended family members. This indicates that extended family support collaborates with family of origin support …

Binding, Protection, And Rna Delivery Properties Of Porous Silica Nanoparticles In Spodoptera Frugiperda Cells, Emily Nadeau

Theses and Dissertations--Entomology

Traditional methods of pest control are threatened by the development of insecticide resistance, both to traditional insecticides and Bt toxins. Discovery of RNA interference (RNAi) has created opportunities to develop new insect control mechanisms. However, RNAi responses appear to be robust in coleopteran pests, but other orders, e.g. Lepidoptera and Hemiptera, present varied or ineffective RNAi responses. Current delivery strategies for double-stranded RNA (dsRNA) include microinjection, ingestion, and soaking. These approaches have benefits and problems. This study investigates the potential for porous silica nanoparticles (pSNPs) to improve the delivery of dsRNA and induce an RNAi response in Spodoptera frugiperda cells. …

Attitudes Toward Corporal Punishment: The Effects Of Sex, Ethnicity, Military Culture, And Religion, David A. Weisenhorn

Theses and Dissertations--Family Sciences

Nearly 19 out of every 20 parents with 3- or 4-year-old children report spanking their child within the past year, and in schools spanking is a legal form of discipline in 19 states (nearly a quarter-million students received corporal punishment at school at least once during the 2006–2007 academic year). Although corporal punishment is a widely accepted form of child discipline in the United States, little is known about differences concerning attitudes toward the use of corporal punishment among subcultures within the United States.

To address this gap, three studies were designed to examine attitudes toward corporal punishment in a …

Rape Myth Acceptance: A Vignette Approach, Alyssa M. Campbell

Theses and Dissertations--Family Sciences

The purpose of this study was to empirically examine the extent to which rape myth acceptance (RMA) varies according to four key contextual factors—race, the victim–perpetrator relationship, resistance strategies, and the decision to report—among those embedded within college and military cultures. Although sexual assault in a university context has been thoroughly investigated, it is typically in comparison to the general population that may not share the same high-risk elements that promote the environment for sexual assault. Therefore, comparisons of college, military, and a general population were sampled to better understand the attitudes that maintain RMA in these high risk environments. …

Hooking Up Vs. Pornography: A Vignette Approach About Acceptability, Kendall Coffman

Theses and Dissertations--Family Sciences

The purpose of this study was to examine how the intersection of gender scripts, gender identity, and sexual orientation impact perceived narratives and power hierarchies in sexual relationships. To drive participants to verbalize their underlying views about sexual scripts, two highly sexualized and controversial sexual cultures will be examined: casual sex and pornography. Feminist academics and advocates have long argued for a restructuring of sexual politics by implementing feminist principles into personal relations and public life (Connell, 1997). Therefore, competing feminist ideologies will also be assessed to gauge the campus’s feminist climate regarding self-identified feminists’ views on the exploitation and/or …

Comparing Mindfulness-Enriched Weight Management To Current Standard Practices, Teresa M. Lee

Theses and Dissertations--Nutrition and Food Systems

Mindfulness-based interventions have been shown to be effective for numerous diet-related conditions. Mindfulness skills have been theorized to be helpful in improving eating behaviors, and thereby weight management. The purpose of this study was to compare the effectiveness of a mindfulness-enriched weight management program to a standard weight loss program over the course of a 12-week intervention, and weight maintenance over six months. This was a two-group randomized experimental design. One group received a standard weight loss program, while the other group received the same program with an additional mindfulness component. Follow up assessments were conducted twice at three-month intervals. …

Dancing In Time, Aili W. Bresnahan

Philosophy Faculty Publications

This chapter will analyze the experience and, in particular the conscious experience, of dancing in time from the perspective of the trained dancer while performing. The focus is thus on the experience and consciousness of a dancer who is moving her body in time rather than on the experience of a seated audience member or dance appreciator who is watching a dancer move. The question of how temporality is experienced in dance by the appreciator will therefore not be addressed here.

The primary kind of “experience” that will be the focus of my discussion of temporal experience comes from classical …

[Not] Buying It: Prostitution As Unwanted Sex, Rebecca Whisnant

Philosophy Faculty Publications

Noting the relative invisibility of prostitution buyers, or Johns, in discussions of the morality of prostitution, this article criticizes Johns’ behavior on the grounds that they are culpably involved in causing the typical harms of prostitution in the lives of the women whom they pay for sex. Those harms are, at bottom, the result of being habitually subjected to unwanted sex, and they are exacerbated rather than mitigated by such sex being bought and paid for. Efforts to normalize and legalize sex-buying should therefore be resisted.

Appreciating Dance: The View From The Audience, Aili W. Bresnahan

Philosophy Faculty Publications

Dance can be appreciated from all sorts of perspectives: For instance, by the dancer while dancing, by the choreographer while watching in the wings, by the musician in the orchestra pit who accompanies the dance, or by the loved-one of a dancer who watches while hoping that the dancer performs well and avoids injury. This essay will consider what it takes to appreciate dance from the perspective of a seated, non-moving audience member. A dance appreciator in this position is typically someone who can hear and see, who can feel vibrations of sound through their skin, and who can have …

Network Partitioning In Distributed Agent-Based Models, Antoniya Petkova

Electronic Theses and Dissertations

Agent-Based Models (ABMs) are an emerging simulation paradigm for modeling complex systems, comprised of autonomous, possibly heterogeneous, interacting agents. The utility of ABMs lies in their ability to represent such complex systems as self-organizing networks of agents. Modeling and understanding the behavior of complex systems usually occurs at large and representative scales, and often obtaining and visualizing of simulation results in real-time is critical. The real-time requirement necessitates the use of in-memory computing, as it is difficult and challenging to handle the latency and unpredictability of disk accesses. Combining this observation with the scale requirement emphasizes the need to use …

Linking Climate Change And Socio-Economic Impact For Long-Term Urban Growth In Three Mega-Cities, Qi Lu

Electronic Theses and Dissertations

Urbanization has become a global trend under the impact of population growth, socio-economic development, and globalization. However, the interactions between climate change and urban growth in the context of economic geography are unclear due to missing links in between the recent planning megacities. This study aims to conduct a multi-temporal change analysis of land use and land cover in New York City, City of London, and Beijing using a cellular automata-based Markov chain model collaborating with fuzzy set theory and multi-criteria evaluation to predict the city's future land use changes for 2030 and 2050 under the background of climate change. …

Biological Nutrient Removal (Bnr) Process Optimization And Recovery Of Embedded Energy Using Biodiesel By-Product, Sultan Salamah

Electronic Theses and Dissertations

Enhanced biological phosphorus removal (EBPR) as well as biological nitrogen removal require a carbon source to be carried out. Volatile fatty acid (VFAs) (mainly acetic and propionic acids) are the major driving force for EBPR. Many domestic wastewaters have an insufficient amount of VFAs. However, carbon sources such as acetic and propionic acids can be produced using primary solids fermentation process. Due to the cost of VFA production, an external carbon source can be added to the biological nutrient removal (BNR) system that can be fermented to provide the desired VFAs. Glycerol (biodiesel by-product) offers a solution to reduce carbon …

Redox-Active Solid State Materials And Its Biomedical And Biosensing Applications, Ankur Gupta

Electronic Theses and Dissertations

Reactive oxygen species (ROS) are byproducts of physiological processes in human body, and strengthened production of ROS is known to cause acute conditions such as inflammation, aging, Alzheimer's disease, melanoma and ovarian cancer, fibrosis and multiple sclerosis. Therefore, early detection of ROS at nanomolar concentration (at cellular level) and developing more potent antioxidants is essential for regular health monitoring. As an example, ROS are also responsible for inflammation reactions at orthopedic implants-tissue interface triggered by wear debris. Inflammation induced by ROS results in revision surgery. Coatings of redox-active materials exhibiting antioxidant properties on implants have potential to mitigate the inflammation …
