Cold Careers And Occupational Hazards: The Occupational Preferences Of Canadian Serial Killers, Christina E. Ledezma

Masters Theses

Serial killing is a dark and complex phenomenon. As researchers have begun to recognize that serial killing exists and interacts within a broad modern context, how these factors affect its occurrence has received more attention. This includes serial killers’ occupational preferences and the influence that occupations have on their offending. However, studies on serial killers’ occupational preferences have been limited to the United States and the United Kingdom. This thesis sought to classify the occupational preferences of 36 Canadian serial killers and subsequently analyze how these occupations may have influenced their offending, both instrumentally and psychologically.

Confidential Publics: Digital Reconciliation And Queer Muslim Identities, Mariam Mustafa

Masters Theses

In this paper, I trouble constructions of community through exploring temporal spatial configurations of support for queer-identified Muslims living in America. I assert that when community is not something one can physically access, use of the internet to create temporary spaces of community is critical in assessing identity reconciliation between intersectional conflicting identity. As it relates to queer Muslims, where there is a distinct lack of public community, the level of crisis some individuals face is explored through their use of online vehicles to establish social support systems that would otherwise not be available. My paper provides a framework in …

The Development Of Serial Killers: A Grounded Theory Study, Meher Sharma

Masters Theses

The worldview that portrays a serial killer as being a white male, an evil monster with unusual appearance, having dysfunctional relationships (Yaksic, 2015), engaging in animal torture or being sexually or physical abused in childhood, and therefore, sadistically killing for sexual gratification should be challenged (Beasley, 2004). Leyton (1996) and Skrapec (2001) suggested researchers should approach with open minds while searching for knowledge relating to this phenomenon without preconceived assumptions or hypotheses. Furthermore, every serial killers' drive to kill multiple victims may be unique, dependent on his/her history and experiences, and is therefore difficult to quantify (Yaksic, 2015). The current …

Dynamic and diverse representation of black men and women in traditional television has been suppressed through the lens of many problematic ideologies since their introduction to television. Over-the-top video streaming platforms have created new avenues for making televisual content for mass audiences with less censorship and restrictions. This opens a door of opportunity for studying black representation. Focusing on original television written by black men and women for over-the-top platforms, I perform a textual analysis on Luke Cage, Dear White People, and Broke as the population of black-written television on OTT to find the character types and roles …

Blurring The Spectrum: Exploring Queer Conservatism, Austin P. Mejdrich

Masters Theses

Running parallel to the groundbreaking and historic advancement of LGBTQ rights over the past decade has been the rise in the prominence and public discourse of queer conservative thinking. From the Log Cabin Republicans to far-right nationalistic politics, queer conservatives underscore both diverging ideologies within the modern American conservative tradition and the increase of far-right politics in Western societies. This study argues that queer conservatism, while traditionally less explored in the broader context of sexuality politics, is consequential to an understanding of the LGBTQ community and queer politics. Thus, an exploration of queer conservatism as a political ideology is explored, …

The Relationship Between Resilience, Coping, And Social Media, Lillian N. Hurley

Masters Theses

This study was designed to explore relationships between measures of resilience, coping strategies, social media usage, and depression. Resilience refers to one's ability to endure and recover from adversity. Many theories about what contributes to the development resilience have been explored without a clear consensus. Taormina (2015) argued that adult personal resilience is comprised of four dimensions - determination, endurance, adapatability, and recuperability. Coping, a construct related to resilience, is the process of regulating emotions, cognition, behavior, physiological responses, and the environment in response to stressful events. Past research indicated those with poorer mental health have the tendency to use …

Laser-Aided Additive Manufacturing Of Glass, John Michael Hostetler

Masters Theses

“This thesis presents various approaches for the laser-aided additive manufacturing of glass. First, a technique is investigated to create free-form, low to zero coefficient of thermal expansion structures out of silica-gel. A CO₂ laser was coupled through a gantry system and focused onto a binder-free silica-gel powder bed (15-40 μm particles). Prior to writing each layer, powder is dispensed by sifting it onto the build platform as opposed to a conventional wiper system, avoiding contacting and potentially damaging sensitive parts. After deposition, the parts are annealed in a furnace to increase their strength. The influence of various process parameters …

Effects Of Terrain-Based Altimetry On Navigation Performance, Kenneth Michael Kratzer

Masters Theses

"Navigation filters used during an entry, descent, and landing scenario often receive measurements related to the terrain over which the vehicle is traversing. Models of the terrain can be presented in varying degrees of fidelity, providing increasingly realistic and accurate models of the surface. While it is ideal to provide the filter with the most realistic model possible, the performance is limited by the strict nature of the real time scenario. Therefore, it is of interest to determine what level of fidelity is necessary to achieve an accurate filtering solution. Determining how best to incorporate terrain-related data into navigation solutions …

Analysis And Mitigation Of Parallel-Plate Noise For High-Isolation Applications, Zachary Joel Legenzoff

Masters Theses

"Achieving highs levels of isolation between different functionalities in a PCB can be challenging. One of the major issues is that vertically adjacent planes or area fills in a PCB can form a parallel-plate waveguide with no cutoff frequency and serve as an efficient coupling mechanism between interconnects. Due to the finite size of the conductors, reflections off the edges of these parallel-plate cavities can result in the formation of standing-wave patterns with very high field strengths, resulting in high coupling at certain frequencies. This noise coupling mechanism can be suppressed by connecting the parallel plates together with an adequate …
