Effects Of Resveratrol Supplementation On Glycemic Response And Oxidant Status In Moderately Exercised Mature Quarter Horse Geldings, Jennie L. Zambito
Effects Of Resveratrol Supplementation On Glycemic Response And Oxidant Status In Moderately Exercised Mature Quarter Horse Geldings, Jennie L. Zambito
Graduate Theses, Dissertations, and Problem Reports (ETD)
Resveratrol, a naturally occurring phytocompound is known to exert numerous health benefits including improved insulin sensitivity and glucose tolerance, along with decreased tissue damage due to reactive oxygen species (ROS). This compound is incorporated in a multitude of supplements targeted to performance horses, yet no research in an athletic equine model has been completed to date. Therefore, this study was performed to test the hypothesis that resveratrol supplementation would improve glucose tolerance and insulin sensitivity, while reducing oxidant damage in an exercising model. Six, healthy, fit aged (10.5+/-1.5yr, ~500kg) Quarter Horse geldings were assigned to three treatment groups in a …
Evaluating The Effects Of Morrow's Honeysuckle Control On Vertebrate And Vegetation Assemblages, And Small Mammal Foraging Ecology At Fort Necessity National Battlefield, Charnee Lee Rose
Graduate Theses, Dissertations, and Problem Reports (ETD)
Exotic, Japanese bush honeysuckles (Lonicera spp.; Caprifoliaceae) are tied to a variety of impacts on wildlife and ecosystems. Morrow's honeysuckle (Lonicera morrowii) has become a persistent invader in eastern North America. We organized a restoration initiative at Fort Necessity National Battlefield (FONE), Pennsylvania, USA from 2004--2010. Concurrently, we studied the consumption of Morrow's honeysuckle fruits by small mammals from October--November 2009 and July--August 2010, and determined habitat variables that affected visitation rate to foraging stations. Areas of FONE were invaded by Morrow's honeysuckle after the land had been cleared for agriculture, and routine mowing ceased in the mid-1980s. Our restoration …
Imperial Intentions And Independent Interests: The Ohio Company Of Virginia And Its Agents, Thomas Cresap And Christopher Gist, 1748--1752, Emily S. Hager
Imperial Intentions And Independent Interests: The Ohio Company Of Virginia And Its Agents, Thomas Cresap And Christopher Gist, 1748--1752, Emily S. Hager
Graduate Theses, Dissertations, and Problem Reports (ETD)
Thomas Cresap and Christopher Gist, two common men from Maryland, began working for the Ohio Company of Virginia in 1748, in an attempt to expand the British Empire's claim in the Ohio River Valley by enlarging the colony of Virginia. This thesis analyses these two agents of empire and their trade and diplomacy with the Indians of the Ohio Valley, as well as their mapping and surveying. This thesis argues that these two "on the ground" agents were building the British Empire, through their work for the Ohio Company of Virginia. However, this was not their only imperial tie, there …
Model Based Evaluation Of The Differences Between Full And Partial Flow Particulate Matter Sampling Systems, Nathan Kimble
Model Based Evaluation Of The Differences Between Full And Partial Flow Particulate Matter Sampling Systems, Nathan Kimble
Graduate Theses, Dissertations, and Problem Reports (ETD)
PM has been shown to be harmful to people, animals, and the environment. For this reason PM is a regulated emission. As federal regulation of particulate matter (PM) becomes tighter, the need to accurately measure it becomes paramount. As the limit decreases, it becomes more difficult to measure PM due to the inaccuracies in the measurement equipment, and the nature of the particles to be lost in the sampling system.;This study investigated the error propagation and particle loss in two common PM mass measurement systems, the full flow sampling system, also called the constant volume sampling (CVS), and the partial …
Edaphic And Land Use Influences On Central Appalachian Fens, Sarah Deacon
Edaphic And Land Use Influences On Central Appalachian Fens, Sarah Deacon
Graduate Theses, Dissertations, and Problem Reports (ETD)
Local and landscape-scale factors influence peatland floristic assemblages. Our goal in this paper was to assess the interactions between wetland vegetation communities, edaphic factors, and surrounding land cover in central Appalachian peatlands. Specifically we quantified plant community dynamics in relation to edaphic factors and land cover and identified species level responses to human altered landscapes. Cluster analysis on vegetation data identified 3 vegetation groups; an emergent floristic assemblage, a shrub dominated group, and a group with mixed shrub and emergent vegetation. We found that wetlands with emergent vegetation cover were more often associated with natural land cover, higher pH and …
Preference Reversals And Effects Of D-Amphetamine On Within-Session Delay Discounting In Rats, Christopher A. Krebs
Preference Reversals And Effects Of D-Amphetamine On Within-Session Delay Discounting In Rats, Christopher A. Krebs
Graduate Theses, Dissertations, and Problem Reports (ETD)
Impulsive choice is correlated with behavioral problems such as attention-deficit/hyperactivity-disorder and can be assessed using delay-discounting procedures in which subjects choose between a smaller, more immediate reinforcer (impulsive choice) and a larger, more delayed reinforcer (self-controlled choice). A within-session delay-discounting procedure in which choice was between one food pellet delivered immediately and three food pellets delivered after increasing delays was used to examine effects of adding or subtracting delays common to both reinforcers on impulsive choice in male Sprague-Dawley rats (N = 8). For all subjects, delay discounting was observed regardless of whether delays common to both reinforcers were added …
A Chemical Neural Network And Collective Behavior In Globally Coupled Oscillators, Fang Wang
A Chemical Neural Network And Collective Behavior In Globally Coupled Oscillators, Fang Wang
Graduate Theses, Dissertations, and Problem Reports (ETD)
The nervous system controls almost all actions in the body, and understanding its detailed structure and mechanism is one of the great challenges of science. Artificial neural networks have been modeled computationally to solve specific problems such as robot motion; however, few experimental studies have been designed to simulate biological neural networks because of the lack of experimental media with neural-like properties. An experimental network based on the photosensitive Belousov-Zhabotinsky reaction has been developed, in which the local excitability is controlled by light intensity. The spatiotemporal dynamics of these networks has been characterized, including sustained oscillations and collapse to the …
Weightism: Can Personality Characteristics Predict Prejudice In College Students?, John E. Damm
Weightism: Can Personality Characteristics Predict Prejudice In College Students?, John E. Damm
Graduate Theses, Dissertations, and Problem Reports (ETD)
Bias toward individuals who are obese is one of the last bastions of permissible prejudice. The people who are obese report discrimination in a variety of settings; they experience it with families, employers, teachers, and health-care professionals. Research regarding obesity bias indicates that attribution of personal responsibility is correlated with negative attitudes toward individuals who are obese. Attribution of causality and resulting bias has been linked to specific personality characteristics, specifically the Big Five traits Agreeableness and Openness to Experience. The purpose of this study was to examine the relationship between personality characteristics and obesity bias. Students at a large …
Rate Of Response-Independent Events As Discriminative Stimuli, Andres Garcia Penagos
Rate Of Response-Independent Events As Discriminative Stimuli, Andres Garcia Penagos
Graduate Theses, Dissertations, and Problem Reports (ETD)
The study of stimulus rates is relevant to understanding how discrete events integrated in time come to function as a single molar unit that can be discriminated from other comparable units. Two experiments examined the roles of stimulus rates as discriminative stimuli in a conditional discrimination paradigm. Pigeons responding according to a fixed interval (FI) schedule of reinforcement were presented concurrently with pairs of stimulus rates (response-independent blackouts of the operant boxes), so that access to food was granted if the pigeons pecked a comparison key associated to each stimulus rate. One-blackout versus two-blackouts stimulus rates were used on the …
Contests Over Pastoralism In The Southern Sahara And Northern Sahel, Franklin Charles Graham Iv
Contests Over Pastoralism In The Southern Sahara And Northern Sahel, Franklin Charles Graham Iv
Graduate Theses, Dissertations, and Problem Reports (ETD)
West African pastoral groups (Arab, Tuareg, Toubou, and Fulani) experience contests both within their society, and, with outside agents regarding state integration, land use and development. Pastoral leadership, neighboring sedentary groups, national governments, multinational corporations, aid organizations, and academia all influence the paths pastoralists take in their relationship with the environment, the markets they return to, the animals the shepherd, and the non-pastoral opportunities they pursue, to name a few. The social relations that exist between pastoralists and outsiders can essentially coalesce or break apart pastoral society, depending on the actions taken by the various actors mentioned. The outcomes of …
Functional Analysis And Post-Transcriptional Regulation Of Oocyte-Specific Transcription Factors During Early Embryogenesis In Cattle, Swamy Krishna Tripurani
Functional Analysis And Post-Transcriptional Regulation Of Oocyte-Specific Transcription Factors During Early Embryogenesis In Cattle, Swamy Krishna Tripurani
Graduate Theses, Dissertations, and Problem Reports (ETD)
Newborn ovary homeobox (NOBOX) is an oocyte-specific transcription factor essential for folliculogenesis and expression of many germ-cell specific genes in mice. However, the temporal and cell specific expression of NOBOX in bovine oocytes and potential function and regulation of NOBOX in early embryogenesis have not been described previously. Messenger RNA for bovine NOBOX is preferentially expressed in ovaries and undetectable by RT-PCR in somatic tissues examined. NOBOX protein is present in oocytes throughout folliculogenesis and is stage-specifically expressed during oocyte maturation and early embryonic development. Depletion of NOBOX in early embryos demonstrated that NOBOX is an essential maternal derived transcription …
Keeping It Real: A Historical Look At Reality Tv, Jessica Roberts
Keeping It Real: A Historical Look At Reality Tv, Jessica Roberts
Graduate Theses, Dissertations, and Problem Reports (ETD)
In the summer of 2000 CBS launched a wilderness and competition reality show called "Survivor." The show became a monster hit with more than fifty million viewers watching the finale, ratings only second to Super Bowl. That summer and that show forever changed many aspects of the television industry. Reality TV had been around for years, but with "Survivor" it began a period of lightening fast development, growth, and influence. During the past decade, many different reality shows have emerged and this research categorizes those shows into four sub-genres that it is argued all reality shows during this time could …

Graduate Theses, Dissertations, and Problem Reports (ETD)
In addition to being a leading cause of death in the general population, motor vehicle crashes are the leading cause of occupational fatalities in most high-income countries and regions, including the European Union (EU). The primary aims of this research were to: (1) assess the development of occupational road safety policy in the EU through the lens of the policy literature, focusing on the advocacy coalition framework (ACF) as a model of policy change, the role of interest groups, and multi-level governance (MLG); and (2) use the United Kingdom (UK), Sweden, and France as EU case studies to illustrate the …
The Politics Of Self-Provisioning In North-Central West Virginia, Autumn Long
The Politics Of Self-Provisioning In North-Central West Virginia, Autumn Long
Graduate Theses, Dissertations, and Problem Reports (ETD)
Provisioning one's own food appears to be the next step in the politicization of food production and consumption choices. In contrast to more convenient forms of "ethical consumption" such as buying organic or local, household-level food production requires a great deal of labor-time, knowledge, and social support. But does food self-provisioning elicit or engender a particular political consciousness? Based on six months of fieldwork conducted during the spring and summer of 2010, this research employs qualitative methodologies, including surveys, semistructured interviews, and ethnography, to examine the political, economic, and cultural dynamics of household-level food provisioning amongst a sample of food …
Influence Of Selenium On Bluegill (Lepomis Macrochirus ) In Upper Mud River Watershed, Alison M. Anderson
Influence Of Selenium On Bluegill (Lepomis Macrochirus ) In Upper Mud River Watershed, Alison M. Anderson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Selenium based criteria for aquatic ecosystems have been based on water quality measurements, but recently there has been basis to evaluate other aspects, such as whole body, dietary, and sediment levels. Mud River Reservoir, located in Lincoln County West Virginia, receives selenium input from mountain top/valley fill mining activities. The average selenium water levels for the reservoir are above the US EPA water quality standard of 5 microg/L and considered a high hazard for fish dietary consumption based on macroinvertebrate collections. The bluegill population is also a high hazard for selenium influenced reproductive impairment based on bluegill whole body and …
Ozone Induces Nerve Growth Factor Release From Rat Tracheal Epithelial Cells During An Early Postnatal Critical Period, Lynnsey A. Carrell-Jacks
Ozone Induces Nerve Growth Factor Release From Rat Tracheal Epithelial Cells During An Early Postnatal Critical Period, Lynnsey A. Carrell-Jacks
Graduate Theses, Dissertations, and Problem Reports (ETD)
Ozone, one of the major air pollutants in urban areas, produces epithelial cell injury and inflammation in the airways upon exposure. Previous studies have shown that ozone exposure leads to increased substance P (SP) expression in nerves innervating the smooth muscle in the extrapulmonary airway. Nerve growth factor (NGF), a neurotrophin, is known to increase SP expression. To determine the effect of ozone exposure on the release of NGF, a cell culture technique was developed for studying a homogenous rat tracheal epithelial cell population for analysis of NGF mRNA and protein expression. Furthermore, to determine if this effect is age-dependent, …
Effect Of Service Sire On Late Embryonic And Fetal Loss In Sheep, Tammy L. Holler
Effect Of Service Sire On Late Embryonic And Fetal Loss In Sheep, Tammy L. Holler
Graduate Theses, Dissertations, and Problem Reports (ETD)
Very few authors have studied the effect of the sire on the outcome of pregnancy in sheep beyond differentiation, development, spermatogenesis, fertilization and early embryo survival. A major limitation in direct selection for increased sire competence is that males need to be selected mainly on the performance of their female relatives and females do not express lambing traits until at least one or two years of age. This selection process can be accelerated by studying prenatal survival ability of individual ram's progeny.;The objective of the present study was to identify occurrence of late embryonic and fetal mortality in relation to …
Properties Of Polyvinyl Alcohol Nanocomposites Reinforced With Cellulose Nanocrystals Of Red Oak Residues, Peter Michael Jacobson
Properties Of Polyvinyl Alcohol Nanocomposites Reinforced With Cellulose Nanocrystals Of Red Oak Residues, Peter Michael Jacobson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cellulose is an abundant, low cost, and robust biopolymer that is possible to implement in reinforcement of composite materials. Utilizing cellulosic nanocrystals, which can be isolated from cellulose fibers, nanocomposite biofilms are currently of interest to the packaging, medical, and pharmaceutical industries. At this time, hardwood cellulosic nanocrystals and nanocomposites are understudied. Therefore, this research characterized and examined the possibility of using hardwood residues for nanocomposite formation and implementation. Red oak (Quercus rubra) heartwood and sapwood residues were collected from 2005, 2006, and 2007 harvest sites located within West Virginia and were de-lignified by acidified sodium chlorite. Cellulosic nanocrystals were …
Effects Of Fixed-Time Reinforcement Schedules On Resurgence Of Positively Reinforced Problem Behavior, Tonya M. Marsteller
Effects Of Fixed-Time Reinforcement Schedules On Resurgence Of Positively Reinforced Problem Behavior, Tonya M. Marsteller
Graduate Theses, Dissertations, and Problem Reports (ETD)
Resurgence of problem behavior following the discontinuation of DRA interventions may be prevented by response-independent reinforcer delivery. In basic research, response-independent reinforcer delivery following DRA prevented resurgence of the initially reinforced response and maintained alternative responding. The present study evaluated if these results were generalizable humans by assessing if fixed-time (FT) reinforcer delivery following DRA would prevent resurgence of problem behavior and maintain appropriate behavior with 4 children with disabilities. For all participants, EXT following DRA produced resurgence of previously reinforced problem behavior and reduced appropriate requesting, but FT reinforcer delivery following DRA did not produce resurgence of problem behavior …
Controlled Substance, Ron Hollingshead
Controlled Substance, Ron Hollingshead
Graduate Theses, Dissertations, and Problem Reports (ETD)
My MFA thesis and supporting exhibition will highlight sculptural work I have created that deals directly or indirectly with circumstances surrounding personal health problems. A recent L4-5 micro-discectomy and the following complications have given much inspiration for my art making. I use this personal narrative as a jumping-off point to create object-based artwork that brings up larger, more universal themes, such as body, disability, pain, and pharmaceutical use. I will explain how the creation of artwork about the process of healing brought with it its own catharsis.
Reboot, Nick Lejeune
Reboot, Nick Lejeune
Graduate Theses, Dissertations, and Problem Reports (ETD)
I am an artist that works with technologically obsolete materials in order to elevate them to have purely aesthetic, sublime qualities. Creating my art this way has led me to profile and understand hoarders; those who collect materials that are otherwise socially useless. They collect these objects to the point where the collection act becomes an obsessive psychological disorder. This thesis will prove that while I identify with those who struggle with this disorder, my own collection tendencies lend themselves to being more related to the processes of contemporary artists and their need to reconfigure the original use of objects …

Is A Poor Quality Nutrition Environment A Contributor To Obesity Prevalence In School-Age-Children In West Virginia?, Anna M. Chetrick
Graduate Theses, Dissertations, and Problem Reports (ETD)
In recent years there has been considerable interest in describing and explaining increases in the prevalence of overweight and obesity. The quality of the nutrition environment, including the availability and price of healthy foods options, has been suggested as a likely contributor. This project was developed to investigate the relationship between weight status and the nutrition environment in school children in two West Virginia counties. The Nutrition Environment Measures Survey (NEMS) was conducted in Monongalia and Marshall Counties, WV. From NEMS survey data nutrition environment quality scores were calculated for 79 retail food outlets, including grocery, convenience, general, and department …

These structures have housed the Hakka people of the Fujian Province, China in natural yet modern housing that has provided benefits over newer building materials. The key building material, rammed earth, which is used for the walls of the Hakka Tulou structures, has provided structural stability along with thermal comfort to the respective inhabitants of the Hakka Tulous.;Through material testing and analysis this study has examined how the Tulou structures have maintained their structural stability while also …
Cologne During The Witch Hunts, 1627--1662, Megan E. Mcgee
Cologne During The Witch Hunts, 1627--1662, Megan E. Mcgee
Graduate Theses, Dissertations, and Problem Reports (ETD)
This thesis examined Cologne during the years that witchcraft persecution was the highest in the city, from 1627-1662. By using a microhistorical approach on primary sources it found that strained relationships were the chief causes of the accusations. This thesis also discovered that in Cologne, at least, all of those under the age of 30 confessed to witchcraft while all of those above the age of 30 denied the accusations. It did this by both statistical analysis of the questions asked of the accused as well as in depth analysis of the answers that the accused gave their judges.
Expression Of The Cytosolic Phospholipase A2 Isozymes In The Human Breast Cancer Cell Line Models Mda-Mb 231 And Mcf-7 And The Normal Breast Cell Line Model Mcf-10a, Debolina Ganguly
Graduate Theses, Dissertations, and Problem Reports (ETD)
Breast cancer remains one of the leading causes of cancer related death among women worldwide. Numerous reports have provided evidence of a role of inflammation in the onset and progression of many cancers, including breast cancer. A mechanism that leads to inflammation involves the arachidonic acid (AA) pathway, which leads to the production of a group of pro-inflammatory bioactive lipids, collectively known as the eicosanoids. Despite evidence of AA and the eicosanoids in cancer, limited work has been done on the enzyme cytosolic phospholipase A2 (cPLA2) that provides the unesterified AA that can be used for eicosanoid generation. The present …

Cardiac sudden death (CSD) is the leading cause of death in the United States. Although the causes of CSD are not understood completely, cardiac arrhythmias have been indicated as the major contribution to CSD. The main purpose of this thesis is to investigate the mechanisms underlying cardiac arrhythmias, therefore providing scientific basis for clinical applications in the future to lower the rate of CSD.;My thesis contains four chapters. Chapter 1 aims to examine a novel role of tyrosine phosphorylation in the arrhythmogenesis. To achieve this goal, a rat arrhythmia model was established without structural remodeling, and the Src tyrosine kinase …
An American "Duchess" In Disguise: John Singleton Copley's Turquerie Portrait Of Margaret Kemble Gage, Elizabeth Rininger
An American "Duchess" In Disguise: John Singleton Copley's Turquerie Portrait Of Margaret Kemble Gage, Elizabeth Rininger
Graduate Theses, Dissertations, and Problem Reports (ETD)
A number of portraits that John Singleton Copley painted in the years prior to the American Revolution show women clad in turquerie. Traditionally, art historians have explained the appearance of this fashion as provincial colonials copying fashions from their parent country. The appeal of the fashion was strong; however, the political, social, and sexual connotations complicate this explanation for the sitters' choice of dress. While the purpose here is not to disprove the explanation of fashion-consciousness, it is to read these portraits from the perspective of the colonized rather than the colonizer. It is an attempt to decode an appropriated …
