For Cause And Countries: Initial, Sustaining, And Combat Motivation In The Royal Air Force Eagle Squadrons, 1940-1942, Timothy Defazio

Master's Theses

Before the United States entered the Second World War, 245 American pilots pledged their service to the Royal Air Force (RAF). Organized into 71, 121, and 133 Squadrons, collectively known as the Eagle Squadrons, these foreign volunteers present an intriguing avenue of soldier motivation analysis. Employing the conceptual framework offered by John Lynn and James McPherson, this thesis analyzes three components of the Eagles’ motivation—initial, sustaining, and combat.

Viewed in context, the Eagles’ decision to join a beleaguered air force reflected a commitment to ideological principles, as the desires to defend England and curb German aggression figured largely into their …

Media Frames And Abortion Issue Polarization, Shianne Galuska

Master's Theses

The abortion issue is one of the most polarizing topics within the public and media sphere. How the media chooses to frame the abortion debate may influence public opinion and individual reactions. Specifically, articles that use incongruent abortion frames (pro-life/pro-abortion & anti-abortion/pro-choice) may be contributing to an ingroup versus outgroup mentality by highlighting who is the ingroup and who is the outgroup, thus generating moral disgust and polarization (characterized by anger, bias, and activism) amongst those with opposing views. This study sought to answer whether presenting individuals with an incongruent abortion frame increases anger, bias, and activism (polarization), as well …

Higher Command: An Examination Of African American Leadership In The Vietnam Era, Amanda Abulawi

Master's Theses

Since the founding of the United States, African Americans have sacrificed their lives to uphold the nation’s democratic ideals, all while being denied equal access to voting, education, employment, and housing rights at home. Military service appealed to many African Americans who hoped it would lead to social and economic advancement for themselves and their race. Despite African American military participation throughout the nation’s history, these soldiers were treated as outsiders through segregated units and often relegated to non-combative duties, until the Vietnam War. This was the first major conflict in which African Americans had been deployed in large numbers …

Testing And Characterization Of Polymer Laminates For Swelling, Absorption, And Cracking, Matthew W. Carlson

Master's Theses

A polymer laminate consisting of multiple layers of proprietary blends of Ethylene Vinyl Alcohol (EVOH) and Thermoplastic Polyurethane (TPU) and used in the construction of air bladders was evaluated for hygroscopic effects driving delamination and multiple layer fragmentation. These air bladders are observed to suffer delamination during a manufacturing process that involves immersion in an alcohol/water solution. A plausible underlying mechanism is differential swelling and absorption by the laminate constituents. Both room and elevated temperature swelling tests were carried out to find the absorption and swelling coefficients of the constituents. These coefficients served as input into a Finite Element Analysis …

Polycyclic Aromatic Hydrocarbons And The Microbiomes Of Two Benthic Species, Samantha Ells

Master's Theses

The presence of oil has been shown to affect the microbiomes of the water column, sediments, and organisms, both by altering the diversity and the composition of those microbial communities. If the microbiome is altered it may no longer provide benefits to its host organism, impacting its ability to survive. Thus, it is important to understand the effects of large-scale contamination events including the Deepwater Horizon oil spill. This study set out to examine the effects of oil exposure on the microbiome of two benthic species, southern flounder (Paralichthys lethostigma) and eastern oysters (Crassostrea virginica) to further understand the effects …

Characterization Of The Bacterial Microbiome Of Exotic Tick Species Collected From Migratory Birds, Raima Sen

Perception Correction: Addressing Social Stigmatization Around Bdsm And Mental Health, Erin Afana

Master's Theses

Mainstream society’s characterization of activities and subgroups as abnormal can result in a long history of being shamed and pathologized, leading to discrimination and stigmatization. BDSM (bondage and discipline, dominance and submission, and sadomasochism) is an alternative lifestyle with a variety of identities, characteristics and practices that are viewed by many as being outside of societal norms. The consequences of this can be seen in how society, in general, views BDSM participants, how the criminal justice system responds to issues involving BDSM, and how the mental health system perceives those who participate in BDSM activities. The purpose of this thesis …

Analysis Of Multi Resonant Switched Capacitive Converter With Imbedded Pcb Elements, Adel Lahham

Master's Theses

The data center industry is headed towards a lower point of load voltages with increased load demands contributing to higher I2R losses in power busses. Raising the bus voltage from 12V to 48V is a popular area investigated today for reducing power delivery losses. Switched capacitive converters (SCCs) are a popular topology used for this purpose. However, SCCs suffer from low tolerance for operating conditions and are unregulated. The proposed multi resonant switched capacitor buck converter (MRSCBC) can resolve these challenges while also providing output regulation. Switch mode power supplies exhibit high electromagnetic noise and with an increased number of …

Los Zetas are considered by security analysts to be a transformative force within transnational criminal organizations (TCO), exporting their unique model throughout Mexico. Los Zetas’ idiosyncratic interventions include their diversification of criminal operations, professionalization of TCO security, sophisticated use of media and technology, extreme forms of violent coercion, and decentralized command structure. This project aims to complicate the narrative that Los Zetas emerged because of top leaders’ sadistic tendencies or due to an inherently violent culture in Mexico by reframing the group’s evolution within historical processes. Moving beyond Los Zetas, this project examines how persons affected by Los Zetas’ indiscriminate …

Upending The "Racial Death-Wish": Black Gay Liberation And The Culture Of Black Homophobia, Kailyn Pope

Master's Theses

This thesis analyzes the origin and impact of Black homophobia found in activist spaces of mid- to late-twentieth-century American society. Black gay Americans were subjected to intersecting forms of systemic and cultural oppression that were exceedingly hard to escape due to both the homophobia in Black spaces and the racism in gay spaces. Black gay activists and artists thus had to create their own avenues of expression where they and others could fully embrace what it meant to be Black and gay. This work utilizes a Black feminist framework to explore the roots of Black homophobia and how this type …
