The Spatial And Behavioral Ecology Of The Eastern Box Turtle In A Suburban Landscape, Emma Rogers

All Theses

Urbanization poses a significant threat to wildlife through fragmentation, degradation, and loss of habitats. Species response to urban development is variable, from species that thrive in urban areas to those that avoid them. Eastern box turtles (Terrapene carolina carolina) can live and reproduce in urban areas; however, reports of population decline throughout the species’ range have raised concerns. The objective of this study was to compare home range size and composition, as well as the microhabitat selection of the Eastern box turtle across a developmental gradient in Clemson, SC. We tracked 14 individuals in habitats along a developmental …

The Impacts Of Wind On Coastal Trees, Julian Halil

All Theses

Trees in hurricane-prone areas are exposed to severe winds and flooding. We studied the physiological and structural responses of forested wetland trees in relation to wind stress. We evaluated the windfirmness of two forested wetland tree species. Baldcypress was chosen because of high survival in post-hurricane studies. In contrast, laurel oak co-occurs with baldcypress yet resists hurricane-force winds poorly. In a static winching study, we quantified the critical turning moment (Mcrit) required to topple both species. Mcrit increased with trunk diameter at breast height (DBH) and crown size. Baldcypress and laurel oak demonstrated similar Mcrit, but regression models indicate baldcypress …

Photobiomodulation Of Bovine Oocytes During Maturation Increases Atp Content And Enhances Subsequent Embryonic Development, Kendall Richey

All Theses

Bovine in-vitro production(IVP) of embryos is a growing field for producing offspring with desirable genetics in the cattle industries. While IVP is effective, oocyte cytoplasmic maturation is compromised, and bovine oocytes matured in-vitro have reduced metabolic activity than those matured in-vivo. Mitochondria are the central unit of oocyte metabolism, producing ATP through OXPHOS. Photobiomodulation is a light treatment reported to improve metabolic activity. In five experiments, we measured the effects of photobiomodulation treatment with red LED at 16-(L-16) and 20 h(L-20) of bovine oocyte in-vitro maturation on subsequent embryonic development, mitochondrial activity and nuclear progression. Bovine COCs were aspirated …

Symptom Clusters In Individuals Seeking Treatment For Gambling Disorder, Blaine Stiglets

Electronic Theses and Dissertations

The fifth edition of the Diagnostic and Statistical Manual for Mental Disorders (DSM-5) presents the criteria for Gambling Disorder (GD) as a unidimensional construct where each additional symptom corresponds to increased severity. Many individuals experience addiction symptoms in specific symptom clusters, with membership to one profile of symptoms or other better-representing disorder severity than raw symptom counts. This study explored whether similarly informative symptom clusters exist among adults seeking treatment for gambling harms. The sample included 444 adults (Mage= 44.95) who completed an assessment of DSM criteria for GD at intake. Through a latent class analysis of GD criteria, three …

Do Emotion Dysregulation And Internalized Shame Mediate The Relationship Between Borderline Personality Disorder Symptomology And Criminal Involvement?, Madison Smith

Electronic Theses and Dissertations

Borderline personality disorder (BPD) is a severe and debilitating mental disorder that is over-represented within the criminal legal system (CLS), with 15-29.5% of individuals in the CLS meeting criteria. However, little research has examined mechanisms leading to criminal involvement within this population. Potential mechanisms include positive/negative emotion dysregulation and internalized shame, which (aside from positive emotion dysregulation) have been linked to criminal involvement in other populations. Research has yet to examine these constructs as mechanisms explaining criminal involvement among individuals with BPD. This study examined positive/negative emotion dysregulation and internalized shame as mechanisms of the relationship between BPD and criminal …

Electrochemiluminescence Using Pencil Graphite Electrodes And Screen-Printed Carbon Electrodes Interfaced With A Simple Imaging System, Sandra Ehigiator

Electronic Theses and Dissertations

Electrochemiluminescence (ECL) is a phenomenon whereby electrochemical reactions generate a product that is capable of emitting light. ECL’s high sensitivity, selectivity, extremely low background, and relatively simple instrumentation make it particularly well-suited for chemical sensing and biosensing strategies. Here we report a simple ECL imaging system based on a camera interfaced with a zoom lens to compare pencil graphite electrode (PGE) and screen-printed carbon electrode (SPCE) arrays as ECL platforms. With this system, ECL signals generated from tris(2,2′- bipyridine)ruthenium(II) chloride hexahydrate ([Ru(bpy)3]2+) using co-reactant tri-n-propylamine (TPA) were linear with respect to [Ru(bpy)3]2+ concentrations from 9 to 450 μM. Detection limits …

Preliminary Evidence For The Validity And Reliability Of A Modified Adverse Childhood Experiences (Aces) Scale: The Variability In Aces Scale, Mary Jo Hedrick

Electronic Theses and Dissertations

Adverse Childhood Experiences (ACEs) research has proliferated in the last twenty years with significant research demonstrating the detrimental effects of early childhood adversity. While many measures purport to measure ACEs, very few capture the intensity of ACEs while still calculating the traditional “ACEs tally.” Thus, it is the goal of this dissertation to collect evidence for an expanded ACES measure. The Variability in Adverse Childhood Experiences Scale (VACE) measure builds upon the original ACEs and captures interval level data. Two survey-based studies were conducted in which convergent and criterion related validity and test-retest reliability evidence were collected. In …

The Greater Implications Of Self-Perceptions Of Aging Among Younger Adults: Results From The Socially Nutritious Volunteer Training Program, Ashlyn Cobble

Electronic Theses and Dissertations

The rapidly growing rate of the older adult population has created a need to better understand younger adults’ self-perceptions of aging and current trends of ageism. The purpose of this secondary data analysis research project was to determine changes, if any, in participants’ self-perception of aging after the Socially Nutritious facilitator or nutrition ambassador volunteer training, which aims to develop knowledge and skills related to aging trends, older adult nutrition, preventing ageism, and communication and educational considerations when working with older adults. Findings indicate that participants with more frequent interactions with older adults had a more positive perception of their …

Validation Of A Novel Heritable Rodent Model Of Drug Abuse Vulnerability In Psychosis And Investigation Of Therapeutic Targets, Loren D. Peeters

Electronic Theses and Dissertations

Schizophrenia is a severe neuropsychiatric disorder of largely unknown etiology that is often accompanied by high rates of cigarette smoking, reduced quit success, and high relapse rates. Dysregulated dopamine signaling and aberrant synaptic plasticity in the mesocorticolimbic pathway are implicated in the pathophysiology of schizophrenia and conferred substance abuse disorder and relapse vulnerability. Genetic factors are presumed to play a significant role in the development of schizophrenia, with a 40-50% concordance rate for monozygotic twins, although genetic markers are inconsistent. As such, epigenetic factors have instead been implicated. Specifically, there is strong evidence to suggest DNA methylation at several candidate …

Healthcare Providers’ Screening And Counseling For Tobacco Use Among Youth In The United States: Prevalence, Practices, And Providers’ Perspectives, Adeola Omolade Ayo

Electronic Theses and Dissertations

Youth tobacco use is a public health concern in the United States (U.S.) with about 2.8 million middle and high school youth reporting current tobacco use in 2023. Healthcare providers (HCPs) can play a crucial role in addressing youth tobacco use through screening and counseling, yet rates of these interventions are suboptimal. Tennessee has a high prevalence of youth tobacco use and not much is known about these interventions in Northeast Tennessee. This study has several objectives: 1) conduct a scoping review of available evidence on screening and counseling for youth tobacco use and identify related gaps; 2) assess youth …

Design And Validation Of A Test For Teachers: Measuring Knowledge Of Trauma, Jennifer B. Bilbrey

Electronic Theses and Dissertations

Research and interest in trauma-informed pedagogy have grown substantially. Trauma-informed pedagogy includes knowledge of trauma symptoms, associated behaviors, and environmental and instructional trauma-informed strategies. Various scales measure attitudes and experiences with trauma-informed practices; however, the literature suggests a lack of validated tests measuring teachers' knowledge of trauma. Reliable and valid tests measuring knowledge are critical when determining the professional development needs of both pre-service and in-service teachers. This multi-phase study aimed to fulfill this need by creating the Teachers’ Knowledge of Trauma (TKOT) test. With the guidance of literature and qualitative data from eight early childhood professional peers, a 50-item …

Role Of Arabidopsis Ltp12 In Environmental Stress Response, Bikram Giri

Electronic Theses and Dissertations

Lipid transfer proteins (LTPs) constitute a pervasive class of small proteins implicated in many biological and physiological processes, including seed development, germination, cuticle formation, and abiotic stress responses. In this study, we explored the role of Arabidopsis LTP12 protein in mitigating environmental stresses. To address this, we analyzed the T-DNA knockout mutant ltp12, focusing on its responses to salinity and osmotic stress. Utilizing antioxidant enzyme assays, phenotypic analyses (including water loss, chlorophyll content, seed germination rates, root length, and relative water content), and lipid profile analysis via Thin Layer Chromatography (TLC), we found that ltp12 mutants showed reduced catalase and …

Characterization Of The Role Of Tobacco Deacetylase Enzyme Sip-428 In Mediating Environmental Stress, Zahra Barati

Electronic Theses and Dissertations

Abiotic stress poses a significant threat to crop productivity and food security. In this study, we focused on understanding the role of SIP-428, a SABP2-interacting protein, in mediating plant responses to environmental stresses. Transgenic tobacco plants overexpressing SIP-428 were subjected to salinity and drought stress. The overexpression of SIP-428 led to diminished growth under both stress conditions, indicating a negative impact on stress tolerance. Specifically, SIP-428 overexpression resulted in a reduction in catalase activity, while peroxidase activity remained unaffected. These findings suggest that SIP-428 plays a negative regulatory role on the catalase activity during abiotic stress, which may contribute to …

No Tolerance For Zero Tolerance: Teacher Perceptions Of Restorative Practices, Meghann Ramsey

Electronic Theses and Dissertations

The original design of zero-tolerance policies was meant to support school safety through an anti-drug and violence campaign but in the years following their implementation, school districts have employed them repeatedly without merit. Exclusionary practices have become controversial, leading to high rates of recidivism, imbalanced implementation toward minority groups, and the loss of learning while suspended or expelled. Just as effective educators respond and intervene to instructional practices that are not proving successful, an overhaul of disciplinary practices was necessary for academic and emotional health. Restorative practices have emerged in recent years as an alternative process to the antiquated system …

An Exploratory Study Of The Southern Subculture Of Honor In East Tennessee, Rachel Cohen

Electronic Theses and Dissertations

The culture of honor theory proposed by Nisbett and Cohen (1996) addresses the historically higher rates of violent crime in the Southern United States, as well as the disparities that can be observed in the laws, beliefs, and social expectations between the South and other regions. Previous research has reported significant differences between the beliefs of acceptable violence among Southerners compared to non-Southerners; however, no research has been conducted comparing different demographic groups of Southerners. The current study sought to evaluate whether there were observable differences between various demographic attributes such as gender, race, age, educational attainment, political affiliation, prior …

Changes In Young Adults’ Perspective On Ageism After Participating In A Virtual Nutrition Education Program With Older Adults, Julianne Hensley

Electronic Theses and Dissertations

The growing older adult population has led to increased ageist tendencies among younger generations. Previous research suggests that ageism is associated with cognitive and physical decline among older adults. This mixed-methods research project examined changes in ageist perceptions among graduate student facilitators and undergraduate nutrition ambassadors after participating in a training that included information about healthy aging, addressing ageism, and communicating with older adults. Results from a secondary data analysis of pre-test/post-test data and thematic analysis of semi-structured interviews with facilitators of Socially Nutritious, a virtual nutrition education program for older adults, indicate that ageist perceptions decreased after the …

Efficient execution of such machine vision perception tasks on resource-constrained edge devices, especially in terms of ensuring …

Mast Cells In Mammary Carcinoma, Alexandria M. Ashbaugh

Undergraduate Honors Theses

Breast cancer (BC) is an aggressive disease that takes the lives of thousands of women every year. Although knowledge and treatment of this disease have improved over the years, much is still to be discovered about BC. One area of expertise that we are currently trying to learn more information about is the mast cell (MC) and its role in BC growth and development. The MC is an immune system component discovered in tumors' extracellular matrix (ECM). As a tumor grows within body tissues, the tumor recruits the MC from surrounding connective tissues to the tumor, using signaling cytokines such …

History Of Physical Neglect And Current Food Insecurity: Moderation By Mental Health Symptoms, Brooke Welsh

Undergraduate Honors Theses

Food insecurity has been a topic of concern for many years. While many actions have been taken to try to reduce rates of food insecurity, further research should investigate whether certain events may increase likelihood of this experience. Thus far, a large amount of research has been completed on how adverse childhood experiences (ACEs) can impact chances of experiencing food insecurity as well as how mental health symptoms can impact these chances. However, there is little research showing that mental health symptoms may moderate the relationship between having ACEs and food insecurity as an adult. A sample of 124 university …

The Effect Of Yamanaka Factors On The Metastatic Potential Of Breast Cancer Cells, Riley Mendonca

Undergraduate Honors Theses

The mortality associated with cancer is most commonly a result of it spreading to other tissues and organs in a process known as metastasis. For carcinomas to do this they must first break through the basement membrane containing them to interact with the stroma. This is known as an epithelial-mesenchymal transition and occurs when carcinomas suppress their original epithelial qualities in order to adopt more mesenchymal ones. This involves cancers dedifferentiating from their original cell type to lose the specialized features that distinguished them and where they came from. As cancers become more invasive, this dedifferentiation becomes more pronounced. Recent …

Examining Attitudes Towards Scientific Research, Charles Ian Johnston

Undergraduate Honors Theses

Undergraduate students are often anxious about participating in a research experience. In this study, students conducted research as part of their introductory biology course and were then surveyed using the Attitudes toward Research Scale, to understand their views on research. Students were surveyed at the beginning and end of the semester, and their scores in five attitudinal categories were compared. The attitudes examined were usefulness of research, positive attitudes towards research, relevance of research, difficulty of research and anxiety towards research. We hypothesized that participation in research as part of a course would improve students’ attitude toward research. Initial analysis …

Bipedalism Is A Balancing Act: Talus Landmarking In Facultative Bipedal Primates, Anita Patane

Undergraduate Honors Theses

Obligate bipedal locomotion, mandatorily walking on two legs, is vastly important as it is the fundamental precursor to the human lineage; it precedes tool usage and language. Chimpanzees, our closest living ancestors for the human ancestral condition, are often the proxy and are the dominant subject of human bipedalism studies. There are additional species, such as arboreal Black Spider Monkeys (Ateles paniscus) who habitually travel through the trees bipedally. These facultative bipedal primates (FBP) introduce a new lens to how modern human talus and calcaneus’ mobility has adapted to environmental shifts such as the transition from arboreal to …

End-Of-Life Patient Communication: Exploring Comfort, Communication And Education Of Healthcare Professionals For End-Of-Life Care, Madison Gremillion

Undergraduate Honors Theses

Historically, the medical field has viewed death and dying as incurable ‘medical failures,’ and as a result, many healthcare professionals have difficulties when facing a patient who is dying or at the end of their life. These individuals will use avoidant behavior to avoid end-of-life (EOL) patients or can have difficulty providing essential aspects of care including communication, that contribute to building a strong relationship between the healthcare provider and patient. For the healthcare professional (HCP), this can stem from anxiety related to thoughts of death and a lack of educational support or experience. The study of death is where …
