Netflix And Kill: The Role Of True Crime Consumption In The Development Of Acquired Capability For Suicide, Chandler Jayne Mcdaniel

Theses and Dissertations

The Interpersonal-Psychological Theory of Suicide (IPTS) identifies acquired capability as a key factor contributing to suicidal behavior. Previous research has shown that violent media exposure can increase suicidal risk through desensitization, imitation, and trauma activation. However, little is known about the role of true crime consumption (TCC), a popular form of violent media engagement, in relation to IPTS constructs. This study examined whether TCC predicts acquired capability for suicide, perceived burdensomeness, and thwarted belongingness. A total of 215 participants were retained after data cleaning. Hypotheses predicted that higher TCC would be associated with higher acquired capability (H1), that TCC would …

Toward Approachable Reinforcement Learning: Using Dataflow Application And Large Language Models For Human-Understandable Policies, Joel Thomas Huber

Theses and Dissertations

Optimal decision-making under uncertainty is a challenge in everything from board games to business scenario planning. With visual programming systems, end-users can utilize reinforcement learning (RL) agents to identify an optimal policy in their own stochastic environments. However, while the RL agent can demonstrate that an optimal policy exists, RL polices tend to be opaque and difficult to interpret. This thesis investigates how Large Reasoning Models (LRMs) can generate human-understandable rules from RL policies. I compare multiple approaches and models, varying the format of the RL policy provided to the LRM as well as the prompting strategy. My results show …

Responding To The Urban Canvas: Murals, Preservation, And Placemaking In Meridian, Ms, Katy Kemalyan

Theses and Dissertations

Public murals that depict elements of local culture and history are a creative placemaking tool increasingly used by preservationists invested in the revitalization of their historic districts. As this trend rises, it becomes necessary for preservationists to ask what should be painted, restored, or left alone? Research on public murals neglects Southern mid-sized towns, considerations of existing murals, and historic architecture used as substrates. Rectifying this omission and employing geographic surveys and stakeholder interviews, this study seeks to expand which genres of murals are considered for their creative placemaking value. Normally distinguished primarily by source in literature, community murals, ghost …

Physics-Informed Neural Network For Maximum Detectable Distance Estimation In Mobile Gamma Spectrometry, Nancy A. Ibrahim

Theses and Dissertations

Accurate estimation of the Maximum Detectable Distance (MDD) is critical for environmental remediation, nuclear incident response, and public safety. Conventional approaches assume stationary detectors and rely on computationally intensive simulations, limiting their applicability for mobile, real-time surveys. Mobile gamma spectrometry introduces additional complexities due to detector motion, variable acquisition times, and heterogeneous backgrounds. This study addresses the central question of how effectively a Physics-Informed Neural Network (PINN) can estimate MDD for mobile gamma spectrometry, while maintaining both accuracy and computational efficiency under dynamically changing environmental conditions. A multi-phase approach was employed, combining field data collection, computational modeling, and operational tool …

The Social In The Spiritual: Non-Theistic Spirituality In 12-Step Addiction Recovery, Steph Jacobs

Theses and Dissertations

To investigate whether Western-raised Narcotics Anonymous (NA) members engage in non-theistic spirituality and non-humanist modes of sociality with non-human beings, I conducted six qualitative interviews and a small-scale survey within a Vancouver NA community. The majority of participants practice non-theist spirituality, and three interviewees relate to non-humans in ways not accounted for by Western humanism. Findings suggest that connection and sociality are intrinsically woven into recovery and well-being. This research opens conversations about non-theistic spirituality in NA recovery, non-human sociality and healing, processes of ontological negotiation, and the entanglement of spirituality, sociality, and well-being. Through daily practices of exploration and …

Understanding Outer Membrane Vesicle Biogenesis In Bacteroides Thetaiotaomicron, Evan J. Pardue

Arts & Sciences Graduate Student Theses and Dissertations

Outer membrane vesicles (OMVs) are small proteoliposomes generated by active protrusion of the outer membrane (OM) in Gram-negative bacteria during growth. Over 60 years of experimentation has ascribed numerous functions to OMVs produced by different bacteria. However, the mechanism(s) by which OMVs are produced is poorly understood. Due to this, the field remains controversial because many regard OMVs as byproducts of cell lysis and question their physiological relevance. Previous studies in Pseudomonas aeruginosa and related species confirmed that these microbes undergo programmed cell death that results in the stochastic release of vesicles and cellular contents. On the contrary, Bacteroides spp. …

Unpacking Identity Work Mechanisms For A Person-Centered Approach To Business And Management Education, Carla Campana, Pablo Leao

International Journal of Teaching and Learning in Higher Education

We explore identity work among undergraduate business students who resist the identity prevailing in traditional business schools. The study investigates an educational program that fosters identity work, allowing students to add facets to their emergent identity. Through in-depth interviews, the researchers uncovered a process in which students resist the hegemonic identity of business administrators, seeking alternative experiences that redefine their identity. Our research contribution is two-fold. First, we extend the concept of identity workspaces by introducing three mechanisms: autonomy, a psychological safe space, and group embeddedness. These mechanisms enable students to engage in an identity work process and reidentify with …
