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 …

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 …

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 …

Molecular Interactions Of The Gas–Solid Interface: Svocs On Swelling Clays And San Joaquin Soil Surfaces, Liesl T. Jensen

Electronic Theses and Dissertations

Soil-derived mineral dust plays an important role in atmospheric chemistry by acting as a reactive interface for gas–particle interactions that influence the fate and transport of organic contaminants. Among soil components, clay minerals dominate surface reactivity due to their high surface area, structural complexity, and the presence of chemically active sites arising from cation exchange capacity and surface acidity. Environmental conditions, particularly relative humidity, further regulate these interactions by altering surface accessibility and competitive adsorption processes.

Despite the recognized importance of mineral dust, gas-phase interactions between organic compounds and clay minerals remain insufficiently understood, particularly under atmospherically relevant conditions. This …

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 …

Field-Like- And Self-Spin-Orbit Torques In Magnetic Multilayer Films, Kyle Jeffrey Peterson

Electronic Theses and Dissertations

Spin-orbit torques (SOTs) have been realized as an energy efficient mechanism to manipulate and drive magnetization dynamics in magnetic multilayer films. Their damping-like and field-like components provide distinct pathways for controlling the magnetization, enabling switching, sustaining magneto-oscillations, and driving domain-wall motion with potential applications in nonvolatile memory, spin-based logic, and microwave signal generation. However, the accurate quantification and interpretation of these torques remains complicated by experimental sensitivity, the co-symmetry of the Oersted field and the effective field due to the field-like torque, and assumptions regarding the material layers from which the torques originate. The body of work set forth in …

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 …

Protest, Police, Peace, And Violence: Understanding Variation In Police Violence At Protests, Louis Pascarella

Electronic Theses and Dissertations

Why do police engage in violence at some protests but not others? Existing research highlights the importance of protest characteristics, political context, police culture, organizational incentives, and interactions between protesters and law enforcement.

And There Was Battle In Heaven: Angels, Demons And Depictions Of Good And Evil In The Avesta And 1 Enoch, Christopher Brent Ghan

Electronic Theses and Dissertations

The Zoroastrian texts of the Avesta and the Second Temple era apocalyptic text of 1 Enoch represent two of the world’s most enduring and influential articulations of the concepts of good and evil forces in monotheistic religious contexts. This dissertation applies Bruce Lincoln’s theory of weak comparison to compare the depictions of good and evil intermediate beings – angels, fallen angels and Nephilim in 1 Enoch and yazatas and daevas in the Avesta – to explore how both of these corpuses use these beings to address questions of evil while maintaining their monotheistic natures, and to define and explore their …

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 …
