Latent Profile Analysis Of Trauma Appraisal: Associations With Psychological Problems And Substance Use Moderated By Emotion Dysregulation In College Students With Trauma History, Tram Nguyen

Theses and Dissertations

Empirical research suggests that trauma-related appraisals have significant mental health implications. A prior meta-analysis reported that maladaptive trauma-related cognitions play a central role in the development and maintenance of poor coping strategies (i.e., substance use) and posttraumatic stress disorder. However, less is known about the relationships among maladaptive trauma cognitions, emotion dysregulation, and risk for substance use. The current study sought to provide a comprehensive examination of the relationships among trauma appraisals, emotion dysregulation, psychological problems, and substance use. A systematic review highlighted the lack of a person-centered approach to trauma appraisal research, as well as a lack of research …

Effects Of Fire And Mesocarnivore Exclusion On Small Mammal Population Dynamics And Behavior In A Fire-Maintained Longleaf Pine (Pinus Palustris) Savanna, Varsha Samba Shastry

Theses and Dissertations

Disturbances shape communities through population responses and species interactions. However, the effects of these inter-related factors on primary consumers and their predators are relatively understudied. Therefore, I used a long-term experimental dataset to assess direct and indirect effects of prescribed fire and mesocarnivore removal on community interactions within small mammal populations. Earlier research revealed no major changes in small mammal abundances following mesocarnivore exclusion, but cotton rats (Sigmodon hispidus) had increased home-range sizes and greater body mass in the exclosures. My research specifically focused on examining behavior and population dynamics of cotton rats and cotton mice (Peromyscus gossypinus) as a …

Estimating Leaf Physiological Traits In Eastern Cottonwood And Its Hybrids By Integrating Uav Hyperspectral Images With Statistical And Machine Learning Approaches, Bipin Paudel

Theses and Dissertations

Eastern cottonwood (Populus deltoides) and its hybrids are high-yield, fast-growing short-rotation woody crops with strong potential in bioenergy and industrial applications. Given their genetic diversity, these species require non-invasive assessment of photosynthetic, leaf biochemical, and water-use efficiency traits. These traits reflect plant physiological status, carbon cycling, productivity, as well as nutrient cycling, and hyperspectral remote sensing provides high-resolution spectral information essential for high-throughput phenotyping. Therefore, this study develops a robust framework to predict physiological traits using Unmanned Aerial Vehicle (UAV)-acquired canopy-level hyperspectral reflectance (~400 nm - 1000 nm, with 2.2 nm band spacing) by integrating linear and non-linear machine learning …

Channel catfish were exposed to MC-LR or anatoxin-a, and …

Family Religious Socialization Index: Development And Preliminary Validation, Kaelie Rene Crockett

Theses and Dissertations

A key area of interest for religious scholars is how religious beliefs are passed across generations, or religious socialization. To expand this field of study, a theoretically grounded, validated measure of this construct is needed. This article describes the development and validation of the Family Religious Socialization Index (FRSI), a multi-informant, multidimensional assessment of the processes through which parents socialize religion and faith in their children. Based on Social Cognitive Theory and through a rigorous development and validation process, three subscales were developed to represent the primary processes of religious socialization. The FRSI consists of two parallel scales, a parent …

Identifying The Brain Circuits Involved In Religious Obsessive-Compulsive Disorder, Kiana Bunnell

Theses and Dissertations

Obsessive-compulsive disorder (OCD) is an often-debilitating psychiatric disorder involving a pattern of obsessive thoughts and compensatory compulsions. Symptoms tend to be chronic, leading to substantial emotional burden and significant impairment across multiple domains of daily functioning. Previous research has identified some consistency in the brain regions implicated in OCD. In particular, cortico-striato-thalamo-cortical (CSTC) circuitry has been linked to behavioral features commonly observed in OCD. Moreover, some studies suggest that distinct patterns of brain activation and functional connectivity may be associated with different OCD symptom dimensions, though findings have not been consistent. One symptom dimension of OCD (scrupulosity) is characterized by …

Is “No Change” Really No Change?: A Qualitative Analysis Of Clients With “No Change” On Routine Outcome Monitoring Who Report Improving In Therapy, Audrey Louise Stewart Parker

Theses and Dissertations

Routine outcome monitoring (ROM), the practice of tracking client progress in therapy by administering regular questionnaires to assess functioning, has demonstrated a significant positive effect on psychotherapy outcomes, especially for clients are who not improving as expected. However, some researchers argue the symptom-based measures and outcome classification criteria commonly used in ROM may not represent a complete picture of client change. A recent body of mixed-methods research has investigated these ROM-determined outcome categories to gain insight into client experiences and whether the category and client perception of therapy outcome align. In this investigation, researchers have found significant variety within outcome …

Intensification Of Thermal Energy Storage Systems Based On Sodium Nitrate, Hari Suthan V Mr

Theses and Dissertations

Thermal energy storage (TES) systems employing phase change materials (PCM) bridge the gap between thermal energy demand and supply. The low thermal conductivity of sodium nitrate (NaNO3), an inorganic PCM for high-temperature TES systems restricts charging and discharging kinetics, reducing system-level performance. This thesis investigates the intensification of sodium nitrate-based thermal energy storage systems through the incorporation of different classes of additives. Metal oxides (zinc oxide and aluminium oxide) and carbon-based materials (graphene oxide (GO) and expanded graphite (EG)), were incorporated into NaNO3 to improve its thermophysical properties (thermal conductivity, latent heat, specific heat).

Composites were prepared using low-energy ball …

Guided by the Dynamic, Relational, Ecological Approach to Media Effects Research (DREAMER) model, this study examined longitudinal associations between MER and executive functioning (EF) in early childhood and explored whether respiratory sinus arrhythmia (RSA), a physiological index of regulation, predicted developmental changes. Participants included 175 parent-child dyads assessed across two annual waves when children were approximately 4 and 5 years old. Structural equation modeling was used to test bidirectional associations between MER and EF while …

A Systematic Review Of Posttraumatic Stress Disorder Among Hispanic Immigrants In The United States, Rashel Acireale

Theses and Dissertations

This study systematically reviews the literature on posttraumatic stress disorder (PTSD) among Hispanic immigrants in the United States, a population exposed to cumulative trauma across the migration process. Stressors may occur before, during, and after migration and include violence, family separation, dangerous travel conditions, discrimination, and fear of deportation. Despite these risks, findings on PTSD prevalence remain mixed, and Hispanic immigrants are underrepresented in clinical research and culturally informed interventions. This review examines sample representation, types and timing of trauma, PTSD measurement approaches, and the inclusion of cultural and contextual factors such as acculturation and immigration-related stress. It also evaluates …

Resonant Shock Plate Simulation And Prediction Using Modal Substructuring, Harrison C. Denning

Theses and Dissertations

Aerospace structures such as rockets can experience various shock events during flight, such as stage separation or impacts. These shock events can expose components inside the rocket to large accelerations and stresses which in turn can damage the parts. Shocks are often simulated in the lab using a resonant shock plate test. Resonant shock plate testing is often used to qualify aerospace parts, as it can mimic the shocks experienced during launch and stage separations. However, during the course of development, both the definition of the shock environment and the design of the subcomponent tend to change, so that multiple …

Recognition Of Autism Characteristics In Females: An Examination Of Stakeholders, Laurel Lyn Bishop

Theses and Dissertations

Autism is a neurodevelopmental communication disorder, characterized by differences in social communication, attention, interests, and sensory perception. Diagnostic criteria have historically applied to males, but clinical diagnostic criteria beginning in 2022 now include slight differences in traits comprising the female phenotype. Until recently, autistic females may be missed by the professional and education community or diagnosed later than males. Like their autistic male counterparts, they face an increased risk of suicidal ideation, but they also face more difficulties in peer relationships, academic problems, and increased anxiety and depressive symptoms, but may not get supports. School-age girls spend their days with …
