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, …

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.

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 …

Bayesian Change-Point Detection In Stock And Cryptocurrency Markets Using Shrinkage Priors, Yosalin Sanchez

Theses and Dissertations

Financial markets often undergo abrupt structural changes driven by political, economic, and geopolitical events, leading to substantial volatility. Detecting such change-points is crucial for identifying structural breaks, improving risk management, and enhancing forecasting performance in financial time series. This study proposes a Bayesian change-point detection framework that incorporates both the t-shrinkage prior and the Horseshoe shrinkage prior. These priors enforce strong regularization on successive differences in mean parameters, enabling the identification of piecewise constant structures in time series data. Posterior inference is conducted using Markov Chain Monte Carlo (MCMC) methods, specifically a Gibbs sampling algorithm, which iteratively samples from the …

The Effects Of Ai Adoption On Digital Entrepreneurial Intention: A Meta-Analysis, Xandra Precious Okori

Theses and Dissertations

AI adoption and its widespread use have sparked debates about the future of work, job displacement, and the evolving entrepreneurial landscape. While AI is often seen as a threat to traditional employment, research shows that this emerging technology is more likely to change task structures rather than eliminate entire occupations or industries. This shows that there are new entrepreneurial opportunities, particularly digital, that potential entrepreneurs can venture into. This thesis uses a meta-analytic approach to study the relationship between AI adoption and digital entrepreneurial intention, addressing inconsistencies in current research.
