Reflecting On Psychotherapy In Adolescence: A Qualitative Analysis Of Processes Of Change, John Parigger

Electronic Theses and Dissertations

There is a sharp increase in anxiety and depression symptoms in adolescence, and many forms of psychotherapy are shown to be effective. However, most research has examined average effects for manualized treatments that address multiple areas of functioning, which makes it difficult to determine how psychotherapy causes positive change. Process-based therapy postulates that all psychotherapies work through promoting adaptive biopsychosocial patterns of behavior (i.e., processes of change). Research has increasingly focused on the process-based therapy model, and there is a need for qualitative studies to incorporate lived experience into our understanding of change processes. The current study utilized the process-based …

Kinesiology Department Chairs’ Perceptions Of Their Training And Preparation, Kason O’Neil

Electronic Theses and Dissertations

Department chairs are responsible for leading academic departments in higher education.  These individuals regularly make important decisions regarding such things as managing faculty and academic programming, overseeing budgets, and supporting student needs. Despite these responsibilities, many people become department chairs without receiving formal leadership training. This study explored how kinesiology department chairs across the United States viewed their preparation for the role and the importance of leadership training. A total of 111 department chairs completed an online survey about their background, previous training, and the importance of training for different administrative responsibilities. The results showed that most chairs had little …

Weathering The Divide: Social Determinants, Neighborhood Context, And Systemic Lupus Erythematosus Among African American Women, Vanessa Cl Morman

Electronic Theses and Dissertations

Background: Systemic lupus erythematosus (SLE) disproportionately affects African American women and contributes to racial health disparities in the United States. Although genetic susceptibility influences disease risk, growing evidence suggests that social determinants of health (SDOH), including neighborhood conditions, structural racism, and socioeconomic disadvantage, contribute to disease development and progression. Epigenetic mechanisms may provide a biological pathway linking adverse social conditions to chronic disease disparities. This dissertation examined the influence of SDOH on SLE disparities through evidence synthesis and empirical investigation to inform public health practice and policy.

Methods: This integrated learning experience consisted of three complementary manuscripts. Aim 1 was …

Phytochemical And In-Vitro Cytotoxic Analyses Of Flavonoid Species Isolated From Chromolaena Leivensis, Luke A. Bryant

Electronic Theses and Dissertations

As a leading cause of death worldwide, cancer and its treatments remain a primary source of interest among researchers. Modern studies are looking into bioselective cytotoxicity to create new chemotherapies that do not have the same harsh side effects as those we use today. Natural product research has a promising future for the development of such treatments. Specifically, polar flavonoids may be the key to a bioselective treatment. Such flavonoid species are native to plants, often within flower petals or within the body. A natural antioxidant, they are designed not to harm healthy cells. This study focuses on the plant …

Leveraging Mammal Mycophagy To Determine Environmental Drivers Of Truffle Diversity, Brittany Hartsock

Electronic Theses and Dissertations

Many mycorrhizal fungi are hypogeous (truffle-forming), producing underground fruiting bodies. Studying truffles is inherently challenging due to their hidden nature. However, mycophagous mammals provide a unique opportunity to study hypogeous fungi because they rely on truffles as a food source. Although several truffle species have recently been described in the southern Appalachian region, their fruiting patterns remain poorly understood. To address this, we quantified truffle richness and spore loads from 670 Peromyscus scat samples collected across 42 sites spanning an environmental gradient during 2024 in the Blue Ridge Mountains of East Tennessee. We found that truffle richness and spore abundance …

Exploring Competitive Dynamics Between Pseudomonas Baetica And Salmonella In A Polymicrobial System, Braxton E.M. Stout

Electronic Theses and Dissertations

The global rise in antimicrobial resistance has catalyzed a greater focus on polymicrobial research aimed at characterizing microbial interactions and uncovering new therapeutic strategies. Though it has long been of interest, environmental soil-derived bacteria remain largely under-represented in research and thus uncharacterized in this field. This project aimed to identify soil microbes that display inhibitory mechanisms to potential nosocomial pathogens. Soil sample S1S3-2 displayed inhibitory phenotypes toward numerous bacteria and was identified as Pseudomonas baetica. In both planktonic and biofilm growth, P. baetica was able to inhibit Salmonella arizonae through a contact-dependent and temperature-dependent manner. Screening of a transposon insertion …

Barriers To Veterans Affairs (Va) Healthcare Utilization: Exploring The Underutilization Of Va Healthcare Services Among Rural, West Texas Veterans, Adam G. Rodgers

Electronic Theses and Dissertations

Rural veterans forgo Department of Veterans Affairs (VA) healthcare at disproportionate rates, and this study found that the primary barrier is not enrollment but utilization. Seven of the eight participants were already enrolled yet remained functionally outside the system. The purpose of this qualitative single-case study was to explore why rural West Texas veterans forgo and underutilize Veterans Health Administration (VHA) healthcare. Two research questions examined the perceptions contributing to that decision and the barriers preventing access. Andersen’s behavioral model of health services use provided the framework. Semistructured virtual interviews with eight rural West Texas veterans were analyzed using Braun …

The COVID-19 pandemic disrupted young children’s opportunities for social interaction and emotional development, creating new challenges for early childhood educators as students returned to in-person learning. Little was known about how early childhood educators adjusted their instructional practices to support children’s emotional literacy following the COVID-19 pandemic. The purpose of this qualitative descriptive study was to explore how early childhood educators adjusted their instructional practices to support children’s emotional literacy and socioemotional development following the COVID-19 pandemic. The researcher collected data through semistructured interviews with seven early childhood educators employed in one large public school district in South Texas. Interview …

Harkness Seminars In The Humanities, Sarah S. Novlan

Electronic Theses and Dissertations

This participatory action research study explored the effects of Harkness seminars on students’ cognitive, affective, and metacognitive learning in secondary humanities classes. Educators need an effective, flexible, and adaptive method to promote student learning beyond superficial content acquisition. With the decoupling of virtue formation from knowledge acquisition, knowledge gaps from COVID-19 lockdowns, and the rise of artificial intelligence in student plagiarism, a proven method to address all aspects of student formation is needed. Using a participatory action research framework for this qualitative study, conducted at an independent K–12 school site in Texas, the researcher interviewed six secondary humanities teachers over …

Enterococcus Abundance, Distribution, And Environmental Controls At A Sandy Shoreline, South Carolina, Usa, Helen Kehoe

Electronic Theses and Dissertations

Water quality monitoring crucially protects the health of beachgoers around the world. However, water-adjacent sediments, such as sandy beaches, are known to harbor harmful bacteria, yet are not monitored despite their intensive recreational use. This project monitored the abundance of fecal indicator bacteria (FIB), specifically Enterococci, in sandy beach sediments at beaches routinely monitored for water quality in Myrtle Beach and North Myrtle Beach, South Carolina. Surface sediment core sampling (0-5 cm) in the swash zone was conducted once per month for 4 months at 24 beaches in tandem with state-accredited surf-water FIB monitoring using IDEXX’s Enterolert test (Standard Method …

Comparison Of River Plume Classification Methods Using In-Situ Data, Payton Merica

Electronic Theses and Dissertations

River plumes transport terrigenous materials into the ocean, such as nutrients, pollutants, or sediment. These plumes can be separated into regions, including the source region, near-field, mid-field, and far-field, historically defined broadly by the governing forces in each region. Existing methods for classifying these plume regions are limited and often only take into account a subset of influencing factors. This study seeks to compare prior plume region classification methods, such as the Froude number and Rossby radius of deformation, to dominant dynamics within each region using momentum scaling proposed by Garvine (1995). Comparisons were derived from observational data collected during …

Long-Term Trends And Drivers Of Commercial Shrimp Fisheries Across The Southeastern U.S. Atlantic Coast, Trinity Assels

Electronic Theses and Dissertations

Long-term dynamics of southeastern U.S. Atlantic commercial shrimp fisheries reflect interacting environmental and socioeconomic processes rather than uniform regional decline. However, integrated, multi-state assessments linking these drivers to fishery-dependent indicators remain limited for the region. This study analyzed over four decades (1980–2023) of confidential fishery-dependent data from coastal South Carolina, Georgia, and northeastern Florida, focusing on the region where white and brown shrimp dominate commercial landings. Segmented regression analysis was used to identify structural shifts in long-term trends of landings, participation, and catch-per-unit-effort (CPUE), while multiple linear regression models identified seasonal temperature variables associated with interannual variation in shrimp CPUE. …

Presence And Impact Of Herbicides On Intertidal Benthic Communities, Marco Sanderson

Electronic Theses and Dissertations

The growing reliance and widespread use of herbicides on a global scale is negatively affecting non-targeted biota and, consequently, their ecosystems. Herbicide levels and their impacts have been extensively researched around the world in riverine and lacustrine ecosystems. However, studies of the levels and effects of herbicides on coastal intertidal benthic communities have been lacking. This study focused on testing spectrophotometric methodologies for herbicides (atrazine and glyphosate) and documenting their presence and levels in sediment, water, and biotic tissue of intertidal coastal beaches and marshes of Waties Island and Singleton Swash, Horry County, South Carolina. A laboratory microcosm was employed …

Trophic Ecology Of A South Carolina Estuarine Predator Guild, Shane John Molander

Electronic Theses and Dissertations

Estuaries are among the world’s most productive ecosystems in the world and are characterized by the convergence of two distinct habitats, creating a mosaic of environmental conditions from inland rivers to the nearshore ocean. Many fishes occupy estuaries during various life stages for growth, reproduction, or foraging, and may reside in them seasonally. The co-occurrence of species, particularly upper-trophic level carnivores, can result in competitive interactions for prey resources within a shared environment. Identifying the degree of these interactions as well as understanding basal energy consumption can inform food web dynamics and how overlapping species use shared spaces. I used …

Adolescent Depressive Symptoms And Adult Functioning Within Major U.S. Racial Groups, Summer N. A. Millwood

Electronic Theses and Dissertations

Depression is the leading cause of disability among adults in the U.S and is associated with negative short- and long-term social, emotional, economic, and physical health outcomes. Notably, rates of depression among children and adolescents are rapidly increasing across the globe. Depression in youth disrupts crucial developmental processes that can adversely affect concurrent and longitudinal socioeconomic and health outcomes. Although extant research delineates the consequences of adolescent depression for adult functioning (e.g., lower educational attainment, fewer economic resources, worse physical health), studies that examine these associations within racially minoritized populations are scarce. This gap in the literature is especially striking …

Designing Inclusive Stem Curricula: A Design-Based Study Of Teacher Learning And A Queer Inclusive Framework, Kyle Nolting

Electronic Theses and Dissertations

STEM (Science, Technology, Engineering, and Mathematics) education has historically marginalized queer identities, shaping inaccurate curricula and fostering unwelcoming classroom environments. To address this, my research uses design-based research to investigate the design of queer-inclusive STEM curricular resources. I partnered with in-service secondary STEM teachers amidst a series of professional development courses to co-create curricular resources. My research is grounded in queer theory, using a Gender Inclusive Framework to collaboratively develop inclusive design principles. My findings revealed a strong desire by teachers for more authentic and fluid representations of gender and sexuality in STEM curricula, particularly beyond the biological science discipline. …

Biases Toward Threat In Categorization And Attention Allocation When Evaluating Static And Dynamic Emotional Crowds, Delaney Mcdonagh

Electronic Theses and Dissertations

Visual representations are often biased, and these biases can manifest across many different stages of perception. For example, when categorizing nuanced, ambiguous, or fleeting emotional expressions, most perceivers are biased to interpret expressions as negative. Biases also manifest at the level of attention-allocation as observers dynamically examine and attend to expressions as they visually navigate a crowd. To comprehensively understand biased emotion perception, it remains critical to understand how bias manifests across the process of making emotional judgements, both as observers gather information about faces over time and as they make a final categorization of what they see. Biased patterns …

Behind Prison Walls: Unmasking The Victimization Experience Of A Transgender Inmate: A Narrative Study, Kevin E. Hemminger

Electronic Theses and Dissertations

Transgender individuals experience disproportionately high rates of victimization within the U.S. criminal justice system, at rates some studies estimate as four times greater than those of cisgender individuals (Marchi et al., 2025). Victimization may occur at the hands of correctional officers, institutional staff, or fellow inmates. This narrative study focuses on the life story of a formerly incarcerated transgender woman, tracing her experiences before incarceration, throughout her time at two different correctional facilities in two different states, and her life following release. While Community Based Research (CBR) was not adopted as a formal methodological framework, its principles — centering lived …

Compact 1 Ghz Electron Paramagnetic Resonance Spectrometers For Preclinical Imaging Studies, Tanden A. Hovey

Electronic Theses and Dissertations

Magnetic resonance is one of the most generally useful scientific techniques. New horizons of understanding are revealed as technological advances make possible explorations of nuclear spins and electron spins at higher and lower magnetic fields and electromagnetic frequencies. While the greatest current effort is on ever higher magnetic fields and microwave frequencies, both in nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR), the Eaton lab focusses on developing high signal-to-noise performance EPR at low microwave frequencies. EPR provides information about O2, pH, viscosity, glutathione concentrations, and reactive oxygen species in living organisms that MRI cannot. To yield clinically or …

Three-Dimensional Cell And Nuclear Geometries Inform Tissue Level Fluid Mechanics During Epithelial Remodeling, Liam Joseph Russell

Electronic Theses and Dissertations

During epithelial remodeling, mechanical and molecular programs must coordinate to drive the cell shape changes that enable new tissue topologies. Dynamic morphogenesis requires epithelia to preferentially exhibit solid- or fluidlike properties depending on developmental and biophysical constraints. Convergent extension in the Drosophila germband epithelium is one such remodeling event, during which the lateral ectoderm lengthens by two-fold along the primary body axis while concomitantly shortening orthogonally. This process is an incredibly dynamic and attractable system for studying tissue morphogenesis mechanics in vivo.

Germband extension is driven by oriented cell intercalation through T1 transitions, where cells directionally interdigitate with one another …

Pushing Forward: The Dialectical Experiences Of Apida Psychologists In Predominantly White Counseling Settings, Shaun A. Fossett

Electronic Theses and Dissertations

Asian Pacific Islander Desi Americans (APIDAs) are the fastest growing racial group in the United States, yet they remain significantly underrepresented in the field of psychology and notably absent from research examining the professional experiences of racial and ethnic minority clinicians. Existing scholarship has documented the prevalence of racialized organizational structures, microaggressions, and the enduring “model minority” stereotype that both obscures and exacerbates APIDA challenges in professional environments. However, no known published studies have investigated the non–client-facing experiences of APIDA psychologists working in predominantly White counseling settings. The purpose of this interpretive phenomenological analysis (IPA) study was to explore how …

Investigating Caveolar Systems: Spatiotemporal Quantification Of Caveolin-1 And The Mechanotransducive Function Of Ehd2, Jasper Stanae Farrington

Electronic Theses and Dissertations

Caveolae are 50-100nm cholesterol rich flask shaped invaginations found in many differentiated cells. Namely, these structures have been seen to be abundant in endothelial cells where they are involved in many signaling contexts. However, under mechanical stress, the characteristics of caveolae alter, flattening to increase membrane compliance, while displaced proteins can shift from structural roles to mechanosensitive signaling functions. Caveolin-1 (Cav1) is the principal protein required for Caveolar formation while Eps15 Homology Domain Containing Protein 2 (EHD2) is a membrane ATPase that acts to stabilize caveolae at the surface. Despite their emerging importance, understanding the organization and dynamic regulation of …

Exploring Foundations Of Animal Host-Microbe Interactions In A Freshwater Sponge, Jacob S. Pawley

Electronic Theses and Dissertations

The most ancient eukaryotic immune defense mechanisms evolved in unicellular species. Multicellular eukaryotes, however, expanded these mechanisms to meet challenges unique to multicellular life, including barrier formation, long-distance cell signaling, and coordinated responses that eliminate microbial threats while minimizing damage to the host. As such, animal immune signaling pathways are exceptionally intricate and diverse. Though, most of what is understood about animal host–microbe interactions stems from a small handful of model systems. Here, I evaluate host–microbe interactions and innate immunity in sponges using the highly tractable freshwater sponge, Ephydatia muelleri. I report the discovery of an external host-derived matrix …

A Longitudinal Study Of Achilles Tendon Adaptation In Ncaa Division I Female Gymnasts: Associations With Menstrual Status, Birth Control Use, Pain, Limb Dominance, And Training Exposure, Mattie Jane Hyde

Electronic Theses and Dissertations

This longitudinal study evaluated Achilles tendon (AT) thickness in 22 NCAA Division I (DI) female gymnasts across three consecutive seasons in relation to menstruation, birth control use, pain, limb dominance, training week, and year of collegiate competition. Weekly ultrasound and athlete survey data were analyzed using mixed-effects models for absolute AT thickness and change in thickness from baseline measurements. Associations were primarily characterized by interactions rather than uniform effects of individual predictors. A Pain × Limb Dominance × Week × Year interaction was associated with both thickness outcomes across season-specific and combined analyses, with relationship directions varying by limb, season …

Disrupted Family Ecosystems: Intergenerational Estrangement, Nonnormative Events, And Perceptions Of Established Adults – A Case Study, Seth Wyncott

Electronic Theses and Dissertations

The issue of intergenerational family estrangement has gained increased exposure in research and popular literature; however, significant gaps remain in understanding the lived experience of adult-children who maintain separation from their parents. Complicating matters, the family is not a solitary unit but is intertangled within a macrolevel sociocultural ecosystem. This ecosystem includes normative and nonnormative stressors which are subject to diverse interpretations depending on the historic and evolving character of the family and its members. As such, it is important to examine the dynamic character of estrangement in familial and sociocultural context.

Utilizing a case study method with semi-structured phenomenological …

The Resilient Mother: Exploring Factors That Buffer The Influence Of Early Childhood Trauma On Maternal Self-Efficacy, Brigid Magdamo

Electronic Theses and Dissertations

Childhood maltreatment and toxic stress pose significant risks to both individuals and communities, yielding negative outcomes that can perpetuate across generations— a phenomenon known as intergenerational trauma. Early intervention is imperative to disrupt this cycle of adversity and promote positive outcomes. One promising approach involves leveraging protective and promotive factors that cultivate resilience. Individuals with higher levels of benevolent childhood experiences (BCEs) and greater social support tend to exhibit enhanced self-efficacy, thereby potentially buffering the detrimental effects of childhood trauma. Furthermore, the perinatal period presents a critical juncture where maternal well-being significantly impacts both mother and child. The current study …

Effects Of Ankle Actuation On Stability And Gait Dynamics In Oscillatory Bipedal Walking, Guillermo E. Selva Barrantes

Electronic Theses and Dissertations

Bipedal locomotion remains one of the most challenging problems in robotics and biomechanical modeling due to its inherent instability, underactuation, and the complexity of human gait dynamics. This study presents the design and control of a planar bipedal walking model developed to analyze the role of ankle control in achieving stable and human-like walking patterns. Two configurations were investigated: a five-link point-foot model and a seven-link model that incorporates anatomically inspired feet with heel and toe contact points. Both models were formulated using Lagrangian dynamics and integrated with a compliant contact and friction model to reproduce realistic ground interaction forces. …

Mystical Revelation And Knowledge Of God: Reclaiming Spirituality In Theology Through The Mystics, Elizabeth A. Merski

Electronic Theses and Dissertations

Since the scholastic era, the pursuit of God has occurred preeminently through reason, leading to an imbalanced theology of God that persists to the present day in the form of intellect-centered theology. As a resolution, this work proposes that the mobilization of private, mystical revelation as a source of legitimized theological knowledge of God has the potential to close the existent epistemological gap between reason/belief and theology/spirituality, demonstrating the integral unity between authentic knowledge of God and the receiver’s personal acceptance of God in faith. After examining the required methodological components for the discipline of theology and identifying criteria for …

Integrating Naturalistic Developmental Behavioral Interventions In Inclusive Classrooms To Support Autistic Students, Paige J. Johnson

Electronic Theses and Dissertations

The current trend of an increasing prevalence rate of autism spectrum disorder creates a growing need for evidence-based interventions that can be accessed in the natural environments, such as within inclusive educational settings. Naturalistic Developmental Behavioral Interventions (NDBIs) integrate principles of applied behavior analysis and developmental psychology, and offer effective tools for increasing social communication behaviors in autistic children that align with the neurodiversity-affirming movement. The present study sought to evaluate the effectiveness of Behavior Skills Training (BST) in teaching core NDBI skills to a preschool teacher, examine changes in teacher self-efficacy related to supporting autistic students, and assess the …
