Institutional Strain And Substance Coping: Analyzing Perceived Racial Discrimination As A Predictor Of Adolescent Marijuana Use, Fahad Bin Islam Khan

Electronic Theses and Dissertations

This study examines the relationship between perceived racial/ethnic discrimination, psychological distress, and youth marijuana consumption through the lens of the General Strain Theory. It uses the complete-case sample from the 2023 Youth Risk Behavior Survey (YRBS), which surveyed 17,268 high school students across the United States, in a cross-sectional study. The study used logistic regression analyses to assess the association between perceived racial or ethnic bias (e.g., actual discriminatory experiences), psychological distress, and substance use (marijuana), and how closely emotional stress linked these two phenomena. The results indicate that perceived discrimination has a significant positive association (greater likelihood) with both …

With Equity And Inclusivity For All: Self-Reported Preparedness Of Band Directors To Teach Students With Exceptional Needs, Kendra Jenkins Lee

Electronic Theses and Dissertations

The traditional memory theory of personal identity relies on an implicit storage model of memory to explain how the self persists over time. This model assumes that memories endure as stable representations that can be accurately retrieved, and that such representational continuity grounds diachronic identity. However, contemporary cognitive science demonstrates that remembering is an active and reconstructive process. Each act of recall reorganizes and transforms prior experience during the window of ecphory. This reconstructive reality poses a significant philosophical challenge. If memory is inherently unstable and transformable, it cannot straightforwardly ground the kind of continuity the theory requires.

Decision Value Of Confidence Intervals Versus Significance Testing In Surgical Research: A Mixed Methods Study, Andrew Wilson

Masters Theses and Doctoral Dissertations

The misuse and misinterpretations of statistical analyses in medical research have been discussed for several decades and many authors have suggested this has led to poor clinical decision-making. Significance testing, the conventional statistical approach in medical research, has been suggested to be the leading cause of the misunderstandings. Despite the extensive discussion in the literature, there is limited evidence on whether the problems in medical research are linked to the lack of usefulness of significance testing with clinicians’ decision-making process. The purpose of this study was to investigate what statistical information in published research articles surgeons found valuable for their …

Understanding The Effect Of Perceived Supervisor Unavailability On Job Satisfaction, Counterproductive Work Behaviors, And Intent To Quit, Paul-Augustin Wasner

Masters Theses and Doctoral Dissertations

This study examined the influence of supervisor unavailability on employee job satisfaction, counterproductive work behaviors (CWB), and intent to quit. We introduced perceived supervisor unavailability (PSU), as employee's perception that their supervisor is not present, reachable, or responsive when support is needed. Grounded in Job Demands-Resources and Social Exchange Theory, we looked at personal (role clarity) and organizational resources (perceived supervisor or PSS and organizational support or POS) as mediators of the PSU-work outcomes relationship. Data were collected from on-site and hybrid/remote employees. Perceived supervisor unavailability was significantly negatively associated with job satisfaction and positively associated with intent to quit, …

Thus, the current study examined how crime survivors perceive legal system support and attitudes towards restorative justice, with an undergraduate sample recruited from UTC’s SONA system and an online cloud-survey sample. Participants completed a survey that asked about their victimization experience(s), and legal system and restorative justice attitudes. Analyses examined mean differences between non-victims and victims, and subjective …

Loneliness And Social Support In Shift Work Employees, Jacob Lamprecht

Masters Theses and Doctoral Dissertations

Loneliness, a discrepancy between the desired quantity and quality of one’s relationships and their current relationships, has been connected to increases in mortality, as well as lower job performance, reduced job satisfaction, and increased burnout. However more recent studies indicate that the recipient may not always perceive the support as beneficial, resulting in “unhelpful social support. The present study examined how helpful and unhelpful social support relate to loneliness among healthcare shift workers, a population that may be prone to fatigue and health risks. I hypothesized that helpful support would be negatively related to loneliness and that unhelpful support would …

Supervisor-Focused Impression Management And Social Undermining As Self-Enhancing Responses To Perceived Job Insecurity, J. Luke Wiley

Masters Theses and Doctoral Dissertations

Job insecurity has become a more prevalent and harmful issue across many advanced economies. The present study was designed to investigate two ways in which employees may respond to perceived job insecurity. We hypothesized that employees experiencing job insecurity engage in impression management tactics directed at their supervisor (SFIM) or social undermining tactics directed at their coworkers. We further hypothesized that these processes or effects were moderated by employees’ core self-evaluations (CSE). Data were gathered through targeted sampling to workers in the federal government (Sample 1, N = 91), as well as convenience sampling (Sample 2, N = 146). Results …

Personalized And Adaptive Therapeutic Music Generation From Biosignals Using Knowledge-Guided Multimodal Large Language Models, Amin Amiri

Masters Theses and Doctoral Dissertations

Multimodal generative models are reshaping digital therapeutics by enabling real-time synthesis of personalized content aligned with a user’s physiological and affective state. However, existing systems remain fragmented across modalities and often lack a unified framework that can jointly represent biosignals, natural language intent, music, and video under long-context constraints. This dissertation presents an end-to-end multimodal large language model ecosystem for personalized therapeutic music generation that combines discrete tokenization, evidence-grounded reasoning, and stabilized preference alignment. At the representation layer, the dissertation develops a family of tokenizers that convert continuous biomedical and media signals into compact discrete sequences for transformer-based modeling. Harmonizer …

Breaking The Silence: Examining Sociocultural Barriers And Comfort With Sexual Health And Intimacy In Adolescents, Marcos D. Pena Veras, Kimberly Gross

OTD DEx Reports - College of Pharmacy and Health Sciences

Over the past three decades, adolescent pregnancy rates in the United States (U.S.) have decreased across all ethnic groups (Livingston & Thomas, 2019). However, in the United States, rates among the Hispanic population remain higher than those of other major ethnic groups. Review of the existing literature describes cultural barriers that prevent Hispanic young adults and their parents from engaging in sexual health and intimacy education. These barriers include gender roles, educational attainment and healthcare access, and lack of parental communication (Alzate et al., 2018; Langellier et al., 2021; Durante et al., 2023).

This study utilized a mixed-methods approach and …

A Two-Stage Screening Approach Integrated With Gwas For Rare Phenotypes Such As Spontaneous Haploid Genome Doubling In Maize, Mercy Fakude, Tyler L. Foster, Yu Ru Chen, Ann Murithi, Siddique Imran Aboobucker, Ursula Karoline Frei, Philip M. Dixon, Thomas Lübberstedt

Plant and Soil Sciences Faculty Publications

Spontaneous haploid genome doubling (SHGD) is a valuable trait in maize breeding, enabling the development of doubled haploid (DH) lines without chemical chromosome doubling. However, SHGD is a rare phenotype, expressed in only a small fraction of maize germplasm, making its identification resource-intensive. This study evaluated the efficiency of a two-stage field screening approach designed to identify maize genotypes with high haploid male fertility (HMF), a key indicator of SHGD potential. Simulation analyses showed that evaluating 50 haploid plants per genotype, combined with a 25% HMF threshold, provides an optimal balance between detection accuracy and resource efficiency. Across three growing …

The Impact Of Framing Effects And Moral Values On Prosocial Engagement, Olajuwon Olagbegi

Dissertations

Framing effects can shape perceptions, beliefs and behavior, particularly in prosocial contexts. The current study examined how language framing (social justice, social activism, volunteerism) and moral values influence interest in prosocial engagement across low- and high-cost helping scenarios. Participants (N = 219) were randomly assigned to one of three framing conditions and reported willingness to help in both low- and high-cost situations. They also completed the Moral Foundations Questionnaire. Replicating prior work (Olagbegi and colleagues, 2024), participants were more willing to engage in low- than high-cost helping. Across conditions, social justice framing elicited the greatest willingness to help. Higher fairness …
