Assessing The Impact Of The Tennessee Equine Industry, Olivia Watson

Masters Theses

The Tennessee equine industry is alive and prevalent across the entire state. However, due to the expansiveness of the industry, lack of consistent record keeping, and large discrepancies among reporting agencies, it has proven to be difficult to accurately account for the total impact of the industry in terms of population, demographics, and overall economic impact. The objective of this study was to 1) determine population demographics and economic impact of the equine industry in Tennessee and 2) determine the public perception on the addition of live equine racing within the state. An anonymous, online assessment was developed (March-August 2022; …

"You're Not Thriving, You're Just Trying To Survive The Environment That You're In:" Mental Performance Consultants' Narratives Of Emotional Abuse In Sport, Victoria Lynn Bradshaw

Doctoral Dissertations

Emotional abuse is defined as “a pattern of deliberate non-contact behaviors by a person with a critical relationship that has the potential to be harmful” (Stirling & Kerr, 2008, p. 178). Specifically, in the context of sport, emotional abuse is one of the more frequently occurring forms of abuse (Kavanagh, Brown & Jones, 2017; Kirby, Greaves & Hankvisky, 2000; Wilson & Kerr, 2021). Years after the termination of those emotionally abusive experiences, athletes are left to try and cope with and manage the short and long-term impacts that tend to develop as a result of repeated exposure to harmful behaviors …

Analyzing Youth Engagement And Gender Roles In The Groundnut Value Chain In Uganda Using The Photovoice Research Methodology, Annie Faye Carter

Masters Theses

In regions of East Africa, groundnut (Arachis hypogaea L.) is cultivated as a common cash crop in areas of food insecurity and agricultural-dependent communities. Groundnut, also known as peanut, is a legume with a variety of important uses. This crop is especially popular with small-scale farmers and youth, who seek to harvest a crop which is affordable. As an expected 440 million young people enter the global labor market by 2030, those living in rural areas are at a disadvantage when searching for job opportunities. In Africa, this rural-urban divide has impacted the economic sector and the activities …

Psychological Determinants Of Physical Activity And The Prediction Of Physical Activity Levels In African American Men, Alvin L. Morton Iii

Doctoral Dissertations

African American (AA) men experience disproportionally higher rates of non-communicable, chronic diseases (e.g., cardiovascular, type 2 diabetes, and renal failure) than White men. Physical activity (PA) is known to reduce the progression of CVD, type 2 diabetes, and renal failure. National statistics illustrate that AA men are less likely to get sufficient levels of PA to obtain health benefits. Although many factors (e.g., biomedical, socio-cultural) influence participation in PA, the psychological factors at the individual level are essential to beginning and maintaining activity. Therefore, understanding the psychological determinants of PA in AA men and their associations with meeting national guidelines …

Sphenoidal Sinuses And Spherical Harmonics: Variation And Covariation Of The Most Morphologically Diverse And Least Understood Paranasal Sinus, Katharine Grace Josephine Ryan

Doctoral Dissertations

Understanding the shape variation of the human sphenoidal sinus is important to several areas of research. This includes clinical investigation (sinus pathology and safe endoscopic endonasal surgical practice) and paranasal sinus evolution (for which there is still no consensus). Yet, the sphenoidal sinus has high morphological variation, prohibiting its quantification through traditional geometric morphometric landmarking methods. The sphenoid body, and thus also the sinus contained within, is located directly at the developmental center of the basicranium in humans, where the three cranial fossae meet at the midline, and adjacent to the three synchondroses which are the sites of cranial base …

Design And Development Of The Urban Population Health Observatory To Improve Disease Surveillance And Response, Whitney Brakefield

Doctoral Dissertations

Chronic and infectious diseases have a profound impact on the quality and length of life of populations that suffer from these conditions. Scientists, physicians, and health officials are seeking innovative approaches to decrease the morbidity and mortality of deadly diseases. Incorporating artificial intelligence and data science techniques across the health science domain could improve disease surveillance, intervention planning, and policymaking. In this dissertation, we describe the design and development of the Urban Population Health Observatory (UPHO), an explainable knowledge-based multimodal big data analytics platform. A common challenge for conducting multimodal big data analytics is integrating multidimensional heterogeneous data sources, which …

Impact Of Far-Red Light Supplementation On Yield And Growth Of Cannabis Sativa, Thomas Benjamin Carter

Masters Theses

Far-red light(700-780nm) induces shade avoidance response in many different species of plants. The shade avoidance response triggers a number of changes in the plant such as cell expansion and stem elongation. This cell expansion has shown to increase yields in leafy greens and increase flower set in tomatoes. Despite there being a void in the literature for Cannabis sativa, far-red lights are often advertised to provide several benefits. This study will evaluate the effects of far-red light supplementation on the yield and height of Cannabis sativa. Five cannabis clones were grown under white (410-730nm) light emitting diodes (LED’s) at …

Social Context Influences On Behavior Of Carolina Chickadees, Brittany A. Coppinger

Doctoral Dissertations

This dissertation assesses fundamental social factors that drive variation in calling and other behaviors of experimental flocks of Carolina chickadees. Specifically, I tested how group member familiarity and group composition affected individual behavior. In addition, I performed a direct experimental test of the Social Complexity Hypothesis for Communicative Complexity, which states that groups that are more socially complex will communicate with greater signal complexity than groups that are less social complex. I consider complexity to be a combination of three factors: the number of parts in a system, the variation among the parts, and the variation in the way those …

Using A Cognitive Behavioral Approach In Individual Counseling With Patients Undergoing Bariatric Surgery, Nina Marie Ditommaso

Doctoral Dissertations

Morbid obesity is linked to physical and psychological well-being. Bariatric surgery has shown tremendous success with rapid weight loss in the patient population with morbid obesity. These patients experience issues with weight regain post-surgery, which can be linked to psychological and social factors. Despite this, mental health counseling is rarely offered in bariatric surgery programs. The primary investigator used a six-session Cognitive Behavioral Therapy (CBT) approach in individual counseling with patients following bariatric surgery. The primary investigator used a single case research design to treat four participants. The primary investigator measured the effectiveness of a six-session CBT treatment, assessing for …

Association Between Stream Impairment By Mercury And Superfund Sites In The Conterminous Usa, Karessa L. Manning

Masters Theses

Mercury is a natural element that can cause harm to the brain, heart, kidneys, lungs, and immune system, especially to fetuses developing in the womb. Many natural and anthropogenic factors contribute to mercury in the environment, such as geologic deposits, landfills, gold and silver mining operations, cement production, and atmospheric deposition. Mercury has been identified as a contaminant of concern at many National Priority List (NPL) sites, however, studies on contamination at NPL sites are often only conducted on a local level. This study was to analyze the potential connection between mercury-contaminated NPL sites and the presence of mercury impaired …

Examining The Physical Activity Levels Of Youth With Intellectual And Developmental Disabilities During Physical Education And Recess, Vincenzo Nocera

Doctoral Dissertations

Introduction: It is currently believed that children with intellectual and/or developmental disabilities (IDD) are less physically active than their peers. The school setting may offer a promising solution to allow children with and without IDD to engage in physical activity (PA). However, the current school-based PA levels of this population remain unclear. Therefore, the purpose of this investigation was to compare the PA levels and related context of youth with and without IDD during the total school day, physical education, and recess. Methods: A total of 13 children (n = 3 with IDD) enrolled in first- and second grade participated …

Exploring The Effects Of Traditional And Expert-Derived Attentional Focus Cue Structures On Complex Skill Learning, Kaylee Woodard

Doctoral Dissertations

Instructions that direct attention externally have been shown to enhance motor performance. However, research on learning effects has produced mixed findings, particularly in skilled populations, and particularly when realistic instructional protocols have been used. Most studies have presented an overly simplistic view of attention, such that all-internal focus protocols are contrasted with all-external focus protocols. Expert performers, however, have reported adopting combined approaches, revealing the need for research to test more realistic instructions. The current project was a two-part study designed to investigate the effects of realistic focus instructions on performance and learning. Study 1 was an exploratory study of …

Mediation And Moderation Of Intergenerational Epigenetic Effects Of Trauma, Stefanie Renee Pilkay

Doctoral Dissertations

Trauma and early-life stress have been linked to poor mental and physical health outcomes. In fact, research has identified trauma and stress can influence epigenetic marks on genes that can alter gene activity. It is suspected that epigenetically altered gene activity is involved in behavior and mental health. This may help explain why some individuals don’t experience great benefit from treatment for the effects of stress, and severe mental health symptoms can be chronic for decades or a lifetime. Moreover, some trauma-related mental health symptoms have shown generational patterns that appear linked to epigenetic marks. Therefore, this study sought to …

Conservation Decisions: Designing, Financing And Fundraising For Protected Areas, Rachel Elizabeth Fovargue

Doctoral Dissertations

Establishing protection for conservation is a complicated process that involves many critical decisions, from spatial prioritization to garnering the necessary financial support to complete a project. In my research, I address questions that inform various components of this process. First, I ask questions about protected area design using a case study of a large reef system in Australia. I find that simple design rules can facilitate the pursuit of conservation and extractive management goals. Second, I address questions about costs incurred by the financing of new protection. I establish a unique dataset of projects financed by a conservation non-profit through …

Motivation And Support For Regulatory Changes: A Typology Of Tennessee Wild Turkey Hunters, Cristina Elisa Maldonado

Masters Theses

Hunters form a diverse group with multiple motivations for seeking outdoor recreation experiences. A deeper understanding of hunters’ motivations may benefit wildlife managers in state agencies to cater services and regulations to meet the needs of this diverse group. To determine the motivations of wild turkey (Meleagris gallopavo) hunters in Tennessee, and their attitudes and preferences concerning turkey hunting and management, a self-administered questionnaire was developed and mailed to a sample of licensed Turkey hunters in Tennessee. A multivariate K-means cluster analysis was then applied to identify hunter typologies based on several motivation factors that were derived from …

Spatial And Temporal Heterogeneity Of Carbon Storage And Optimal Provision Of Carbon Storage, Amine Mohamed Ben Ayara

Masters Theses

Human activity, particularly the conversion of natural land cover into human-dominated cover types, is putting increasing pressure on the health of the global ecosystem. Loss of forestland is a major contributor to greenhouse gas (GHG) emissions, which cause climate change because forests can help sequester GHG emission in the atmosphere. However, mitigating climate change by sequestering carbon through reforestation and/or avoiding deforestation is an appealing option because of the potential scale of such sequestration, the possible cost advantages over other mitigation efforts, and the opportunity it provides to incentivize the sustainable use of rural lands. Incentive payments can support forest-based …

Regional Dynamic Price Relationships Of Distillers Dried Grains In U.S. Feed Markets, Matthew Fulton Johnson

Masters Theses

Distillers dried grains with solubles (DDGS) is now a mainstream substitute in U.S. animal feed rations. DDGS is rich in fat and protein content and serves as a competitive feed source in livestock markets. The objective of this study is to identify dynamic price relationships among DDGS, corn, soybean meal, and livestock outputs in context of specific livestock sectors and their geographic location. Four locations associated with a predominant livestock sector are selected for analysis by measuring density and relative proportion of a livestock sector’s grain consumption at the county level. A vector error correction model is applied to post-mandate …

4-H Wildlife Habitat Education Program: A Qualitative Study On Career Exploration, Ronnie Lee Cowan

Masters Theses

There are documented studies on the Wildlife Habitat Education Program (WHEP) that relate to building life skills of participants. However, no literature was found that measured the perceptions of the participants towards a career in wildlife after participating in WHEP. To add validity to the program a focus group was conducted at the Tennessee 4-H wildlife judging contest to describe the WHEP participants’ perceptions of careers in wildlife after the completion of the annual program. Focus group participants indicated that participating in WHEP peaked their interest in wildlife and provided an opportunity to experience the importance of natural resource management.

A New Adaptive Landscape: Urbanization As A Strong Evolutionary Force, Lauren Christie Breza

Masters Theses

Urbanization is rapidly increasing as human population growth steadily grows, but there is little consensus of the ecological consequence of this population shift and almost no information of the evolutionary consequences for local biodiversity. Nearly two-thirds of the world’s population will live in city centers by 2050 with profound impacts on landscapes that can act as important agents of selection. This study aims to identify 1) the net effect of urbanization on species richness, 2) how phylogenetic diversity varies between urban and rural sites, and 3) the strength of urbanization as a selection pressure. First, a meta-analysis was conducted in …

Economic And Environmental Optimization In The Supply Of Switchgrass In Tennessee, Jia Zhong

Masters Theses

The low efficiency of collection, storage and transportation in the switchgrass supply chain has hindered the commercialization of a switchgrass-based biofuel industry, even given its ecological and environmental advantages in carbon sequestrate, soil quality, water use, and pollution pressure. Thus, designing a switchgrass-based supply chain balancing both environmental and economic performance is important to expedite the development of the cellulosic biofuel industry to meet the national energy plan.

The objectives of this study are to 1) determine economic cost and multiple environmental outcomes in feedstock supply chains and 2) identify the relation between the economic and environmental performances. The first …

Mechanisms For Social Influence, Jeremy David Auerbach

Masters Theses

Throughout the thesis, I study mathematical models that can help explain the dependency of social phenomena in animals and humans on individual traits. The first chapter investigates consensus building in human groups through communication of individual preferences for a course of action. Individuals share and modify these preferences through speaker listener interactions. Personality traits, reputations, and social networks structures effect these modifications and eventually the group will reach a consensus. If there is variation in personality traits, the time to reach consensus is delayed. Reputation models are introduced and explored, finding that those who can best estimate the average initial …

The Greenhouse Effect: Decomposition Rates In Human Remains Wrapped In Plastic, Barbara R. Forman

Masters Theses

Determining an accurate estimation of the postmortem interval (PMI) of human remains is important for several reasons. First, it is used to determine whether the individual is recently deceased, and therefore of medicolegal concern. If so, the estimated PMI is used in narrowing the possible identities of the deceased. PMI can also be used in excluding, or convicting, a murder suspect.

Though deviations may occur, it has been found that PMI can be calculated from the decomposition stages with reasonable accuracy (Galloway 1989, Megyesi 2001, Megyesi et al. 2005, Schiel 2008, Simmons et al. 2010). Some factors, such as low …
