Insights Into Androgen Receptor Allosteric Modulation By P,P'-Dichlorodiphenyldichloroethylene Binding At The Binding Function-3 Site And Site-Specific Binding Function-3 Mutations, Emanuel Aggeo Flores

Theses and Dissertations

One of DDT’s metabolites, p,p’-dichlorodiphenyldichloroethylene (DDE), has been classified as an endocrine disrupting chemical (EDC) due to its ability to interfere with hormone signaling by binding to nuclear receptors (NR) such as the androgen receptor (AR).

Structurally, the AR contains a ligand-binding domain (LBD) where endogenous steroids bind. Furthermore, the LBD contains a surface binding site known as binding function-3 (BF-3), which studies suggest exerts an allosteric effect on bound DHT when small, hydrophobic molecules bind.

Here, we present a study that examines how specific BF-3 site mutations and DDE binding affect steroid stability within the LBP utilizing computational methods. …

Climate change is a pressing global issue with diverse mental health impacts. However, the relationship between climate change perceptions and mental health remains poorly explored. Rapid climate change in Alaska makes it an ideal setting to explore these relationships. Thus, 204 Alaskan adults were surveyed to assess their perceptions of climate change and explore the relationships between climate change perceptions, exposure to adverse climate impacts, and psychological distress (i.e., symptoms of depression, anxiety, and climate-related post-traumatic stress). Results suggest that participants agree that climate change is real, human-caused, negative, and impacts areas both close to and far from where they …

A Behavior Analytic Blueprint For Rapport-Building: Investigating The Key Elements For Success, Nelmar Jacinto Cruz

Theses and Dissertations

Rapport can be defined as a positive relationship between people built through specific actions. Building rapport can benefit organizations by improving performance and increasing work satisfaction. Despite these benefits, research on rapport remains scarce. Curry et al. (2019) completed the most recent rapport study and found that rapport-building led to increased productivity and discretionary effort. The present study replicated and extended Curry et al. (2019) and addressed three limitations of their research: the lack of a control group, the large disparity in time spent with the experimenter, and the rigidity of their rapport conversation script. The study was completed in …

A New Approach To Generate Combinatorial Patterns In Logical Analysis Of Data And Its Application To Predict College Retention, Salihah Ahmed E. Jaafari

Theses and Dissertations

Student retention and degree completion remain central challenges for higher-education institutions, with significant implications for student success, institutional effectiveness, and public accountability.

Building on existing LAD formulations, this research introduces two novel pattern generation models, the Best Term …

What Happens When Leaders Don’T Live Up To The Ideal? How The Leadership Perception Gap Can Undermine Leader Development And Intentions, Julia Macgregor-Peralta

Theses and Dissertations

Despite decades of research on leadership development, we know surprisingly little about why capable, confident people choose not to pursue leadership. This study introduces the Leadership Perception Gap (LPG), a construct that captures discrepancies between ideal leader views and the leaders people actually observe, and tests whether those discrepancies reduce the desirability of leadership roles. LPG was assessed using latent congruence modeling (LCM) to compare ideal leader ratings with vignette-based leader evaluations. The vignettes manipulated leadership style (agentic, communal, balanced) and team composition (all-male, all-female, balanced). Participants were randomly assigned to one condition and evaluated their interest in joining the …

Design And Simulation Of Anti-Resonant Hollow-Core Fiber For Sensing Applications, Pravallika Kante

Theses and Dissertations

This thesis presents the design and simulation of an 8-tube single-ring anti-resonant hollow-core fiber for sensing applications, with particular emphasis on methane gas detection at the fundamental absorption wavelength of 3.3 µm. Conventional solid-core silica optical fibers exhibit strong multi-phonon material absorption beyond 2.5 µm, rendering them fundamentally unsuitable for efficient light guidance and direct gas sensing at mid-infrared wavelengths. Anti-resonant hollow-core fibers overcome this limitation by guiding light predominantly through an air-filled hollow core via the anti-resonant reflecting optical waveguide mechanism, in which the thin silica glass walls of the cladding tubes act as Fabry-Pérot etalons that confine the …

Unlocking Innovation: The Impact Of Psychological Safety, Organizational Structure, And Rigidity On The Pursuit Of Innovation Within The Firm, Robert Kyle Rudd

Learning Adaptive Control For Safe Collaborative Autonomous Driving, Fabian Alexis Hernandez

Theses and Dissertations

Connected autonomous vehicles improve urban driving through collaborative perception via Vehicle-to-Everything (V2X) communication. Frameworks such as V2Xverse leverage this collaboration for planning and perception, yet their controllers rely on fixed parameters that cannot adapt to varying traffic. Control Barrier Functions (CBFs) enforce safety by constraining actions within a safe set, but a fixed barrier gain imposes a single operating point: conservative settings reduce throughput while permissive settings under-react to hazards.

This research proposes an adaptive CBF framework that learns state-dependent, class-specific barrier gains via constrained Reinforcement Learning (RL). A compact policy outputs separate gains for vehicles, pedestrians, and bicycles, parameterizing …
