Tracing Hazing Across Adolescence: Examining How Prior Hazing Experiences Shape Hazing Motivation And Tolerance Among Newly Initiated Ifc Fraternity Members, John Michael Vanhorn May 2026

Tracing Hazing Across Adolescence: Examining How Prior Hazing Experiences Shape Hazing Motivation And Tolerance Among Newly Initiated Ifc Fraternity Members, John Michael Vanhorn

Theses and Dissertations

Hazing remains pervasive and underreported, disproportionately affecting adolescent and emerging adult men, particularly within athletic teams and fraternity contexts. Although hazing is most often studied within collegiate organizations, many students encounter hazing behaviors prior to college, yet little is known about how these early experiences shape later hazing perceptions, motivations, tolerance, and masculine norms. Grounded in Bronfenbrenner’s Process-Person-Context-Time (PPCT) model, this dissertation conceptualizes hazing as a developmental process shaped by repeated social interactions, individual characteristics, contextual environments, and time across adolescence and emerging adulthood. Using a two-paper approach with a quantitative, longitudinal survey design, study 1 examined fraternity new members’ …

Wildfire Risk Mitigation Methods To Enhance The Resilience Of Power Systems, Fasiha Zainab May 2026

Wildfire Risk Mitigation Methods To Enhance The Resilience Of Power Systems, Fasiha Zainab

Theses and Dissertations

The resilience of the power system has become increasingly important in recent years and needs to be further enhanced in the future under wildfire conditions. A major concern is the two-way interaction between power systems and wildfires: power systems can ignite wildfires and be disrupted by them. Power system-induced wildfires occur when electrical components, particularly transmission lines, ignite fires due to faults exacerbated by extreme weather conditions. The presence of uncertainties, especially those related to unpredictable weather conditions, makes it difficult to handle and can significantly increase the risk of wildfire. Furthermore, these ignitions not only threaten public safety and …

Experimental Investigation Of The Effectiveness Of Various Stitching Methods On Arresting Mode-Ii Interlaminar Damage Propagation In Geometrically-Scaled Stitched Resin-Infused Composites, Allison Jean White

Theses and Dissertations

This thesis presents an experimental and analytical investigation of mode-II interlaminar fracture in geometrically-scaled quasi-isotropic resin-infused composites, with emphasis on through-thickness stitching as reinforcement. A global-local framework integrating load-displacement response, size effect fracture energy analysis, and digital image correlation-based separation measurements enabled direct comparison between unstitched and stitched configurations. Unstitched laminates exhibited pseudo-ductile behavior but significant post-peak load drops (16.7–26.8%) and a small fracture process zone (FPZ) of 0.73 mm, limiting stable crack growth. Stitching preserved pre-peak stiffness while reducing post-peak load drops by 43–95%, increasing effective fracture energy by 39.7% (to 2.413 N/mm), and expanding the FPZ to 2.85 …

Effects Of A Basketball Match On Heart Rate Variability In Collegiate Intramural Players, Unobatsha Mbaiwa May 2026

Effects Of A Basketball Match On Heart Rate Variability In Collegiate Intramural Players, Unobatsha Mbaiwa

Master's Theses

Heart rate variability (HRV) is a standard non-invasive physiological marker used to asses the autonomic nervous system (ANS) function and cardiovascular adaptability. HRV reflects the natural variations in time between successive heartbeats (R-R intervals), which come as a result of the interaction between sympathetic and parasympathetic branches of the ANS (Shaffer & Ginsberg, 2017). Higher HRV compared to an individual's baseline is normally considered an indicator of greater parasympathetic (rest/digest) influence and more effective physiological recovery, whereas lower HRV relative to baseline is associated with sympathetic (fight/flight) dominance, fatigue, and increased physiological strain. Since the standardized HRV measurement criteria were …
