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 …

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 …
