Climate Change And The Field Of Farm Labor In The Lower Rio Grande Valley, Texas, Cody Richard Mortell

Theses and Dissertations

Farm workers in the United States are often vulnerable to adverse impacts of climate change, particularly extreme heat. This study explores farm workers’ climate change perceptions (CCP) as a mediating force in climate adaptation. Using latent class analysis, in-person survey data (n=404) from Lower Rio Grande Valley, TX (2024) and NOAA data were analyzed. Results were interpreted using Bourdieu’s field analysis framework and his notions of capital and symbolic power. Findings include: a social hierarchy with three latent classes of workers based on economic, cultural, social, and symbolic capital, which statistically significantly affected CCP. Workers in higher structural positions were …

Tracing Anti-Communist Nation-Building In South Korea, Jiyoung Im

War, Diplomacy, and Society (MA) Theses

Anti-communism has always been the cornerstone of South Korea’s national identity. The Rhee government, the very first of the post-Independence era, created the basis for anti-communist state-building. This thesis focuses on how the South Korean and the U.S. governments succeeded in internalizing anti-communism among ordinary civilians through critical historical incidents and cultural policies. By tracing the Yeosu-Suncheon incident and the Korean War, this thesis investigates how the Korean peninsula – which in the immediate wake of liberation from Japanese colonial rule was a relatively open space in ideological terms – shifted to a closed-off and exclusionary space, only allowing anti-communism. …

Soldiers Of Fortune: A Historical Analysis Of American Mercenary Employment, Connor R. Fershin

War, Diplomacy, and Society (MA) Theses

In the Simba Rebellion, which occurred during the Cold War, senior American officials chose to employ mercenaries rather than rely solely on the United States military. Similarly, during the War on Terror, government bureaucrats elected to hire non-state actors to support the American military. To better understand these events, this thesis poses two questions. First, why did the United States government utilize mercenaries in those conflicts? And second, what factors motivate individuals to join a mercenary company in the modern era?

Research into various government databases revealed key documents pertaining to the decision to employ mercenaries in both periods. These …

The Value Of Holidays In World War I America, Laura Kathleen Neis

War, Diplomacy, and Society (MA) Theses

World War I affected what people valued, which in turn impacted American celebrations of the Fourth of July and Christmas. These two holidays became patriotic ways to demonstrate unswerving loyalty to the U.S. government, with charitable pursuits, parties, and even meals altered due to the need for victory. These holidays impacted the war in turn by bolstering morale on the homefront and overseas, and strengthening Americans’ emotional connection to the war.

Surprisingly, the Fourth of July became an international holiday which emphasized the United States’ historical ties to France, and the shared values between the United States and Great Britain. …

In Memoir And Memory: Us Servicewomen Narrating 21st Century Combat, Kelly A. Taylor

War, Diplomacy, and Society (MA) Theses

Over twenty years after the initial invasion of Afghanistan in 2001 and Iraq in 2003, much work remains to uncover the stories of US servicewomen. As the collection of oral histories continues and in the absence of letters, postcards, and other mail for analysis, their memoirs provide some of the first glimpses of the ways 21^st century warfare impacted their experiences in the US military. With shifting “front lines,” the prevalence of improvised explosive devices, and the need for new search tactics, women participated in high rates of combat. Nevertheless, the combat exclusion policy remained in place until 2015. …

Art And Effort, Saul Gabriel Dominguez Ii

Theses and Dissertations

Since childhood I questioned living and my life itself. I wondered the extent of our own free will since people live to cry, to hate, to think they’ve been born simply to die. I use philosophers and some contemporary fiction to portray a lens of living where we must romanticize the present, rather than an uncertain future, and remove the idea that there is a reason for our living. This method of present thinking is a characteristic of a life-well lived. The manuscript will largely be told from my point of view, a young aspiring author with limited experience, through …

Queer Hope And Asexual Desire In Nella Larsen's Passing And Virginia Woolf's To The Lighthouse, Jeremy Buckner

Graduate Theses and Dissertations (2019 - present)

This project examines Nella Larsen’s Passing and Virginia Woolf’s To the Lighthouse together as queer artifacts in hopes of shedding new light on how race and sexuality can be reexamined across national modes of thinking. Although these writers’ backgrounds provide them with different bodies of knowledge, Larsen’s Irene and Woolf’s Lily have much more in common than might first appear. For one, even if racialization is more explicit—and presents more of an obstacle—for Irene, race is an important factor for both characters. Additionally, Irene and Lily both express profound discontent with marriage, Irene in her marriage to Brian and Lily …

A Psychometric Evaluation Of The Intentionality Bias Task, David Willard

Graduate Theses and Dissertations (2019 - present)

Intentionality Bias Task (IBT) provides quick and easy assessment of the tendency to overattribute intentionality to the behaviors of others. The IBT has been used repeatedly in research that has attempted to connect intentionality bias to a wide range of disorders and socio-emotional abilities, including schizophrenia spectrum disorder, autism spectrum disorder, and cognitive empathy. To date, however, there has been no systematic examination of the IBT’s psychometric properties. The present study attempts to fill this gap by testing whether the IBT possesses a reliable factor structure. Specifically, the 34 items of the IBT were written to reflect two types of …

Reframing Rudeness: Exploring Positive Reappraisal As A Pathway From Customer Incivility To Self-Efficacy, Justin S. Boyd

Graduate Theses and Dissertations (2019 - present)

Customer incivility is a persistent challenge for front-line employees (FLEs), often leading to adverse workplace outcomes. This research examined whether positive reappraisal can transform incivility into a source of growth. Grounded in Social Cognitive Theory, the research explored how positive reappraisal mediates the relationship between customer incivility and two key forms of self-efficacy—regulatory emotional and workplace social—ultimately influencing job satisfaction. The moderating roles of perceived organizational support and trait mindfulness were also investigated.

A cross-sectional survey of 296 FLEs was analyzed using partial least squares structural equation modeling (PLS-SEM). More specifically, the results confirmed customer incivility positively predicts positive reappraisal. …

“África Es Nuestro Corazón, Nuestra Sangre”: Cuban Revolutionary Internationalism In Africa During The Inter-Conference Period, 1966-1979, Nathan C. Sommer

Undergraduate Honors Theses

Cuban foreign policy demonstrated continuity in Africa between the Tricontinental Conference of 1966 and the Sixth Summit of the Non-Aligned Movement in 1979. I look at Cuban involvement in African liberation movements of the mid-1960s to characterize the initial launch of Cuba’s yet-to-be fully developed Africa policy. Next, through the lens of the Ogaden War, I examine at the evolution of Cuban foreign policy in the late 1970s. By the time representatives from 82 countries came to Havana in January 1966, Cuba was heralded by the majority of non-aligned countries for their bravery and selflessness. By the late 1970s, significant …

Activity-Based Protein Profiling On Nucleophilic Amino Acid Residues With Pyrocarbonates, James Van Horn

Chemistry & Biochemistry Undergraduate Honors Theses

The complexity of the proteome requires strategies that efficiently characterize protein functions. Activity-Based Protein Profiling (ABPP) is a method that identifies enzyme activity by targeting key catalytic residues. This study focused on histidine, a residue involved in enzymatic catalysis, metal coordination, and protein-protein interactions. Despite its importance, histidine-specific chemical probes are limited due to its variable reactivity. This work developed and characterized a histidine-specific probe using a pyrocarbonate-based mechanism. Singleresidue assays confirmed selective reactivity of the probe with histidine over other nucleophilic amino acids. Further testing on enzymatic proteins and lysed cell proteomes showed that the probe modified histidine residues …

From Basel (1989) To Busan (2024): Developments And Contradictions In The Global Plastic Waste Trade, Megan E. Hughes

Honors Theses

In 1989, the international community convened in Basel to adopt groundbreaking, legally binding legislation on the transboundary movement of hazardous waste. Plastic waste was notably absent from the initial Basel Convention due to the perceived economic value in plastic recycling despite social, economic, and environmental harms. Consequently, the transboundary sale of plastic waste for recycling– known as the Global Plastic Waste Trade (GPWT)– has proceeded largely unregulated, enabling unsustainable plastic consumption while exacerbating environmental justice divides between developed and developing nations. Recent commitments in the GPWT, such as the European Commission Circular Economy Action Plan (2015), China’s National Sword policy …

Political Socialization In Generation Z, Audrey E. Seibel

Honors Theses

This thesis examines the political socialization experienced by Generation Z. With the twenty-first century of American politics characterized by intensely negative emotions, affective polarization, and the augmentation of social media as a means to communicate and engage politically, this thesis argues that the modern political environment has led to a “hot” political socialization. The primary objective of this research was to measure political socialization, and explore the effects of this on current engagement, emotions, trust, and polarization within Generation Z, as well as how the cohort potentially differs from previous generations. The research for this thesis was conducted through the …

Beyond Opioids: The Role Of Polysubstance Exposure In Neonatal Abstinence Syndrome Treatment And Hospitalization, Caelyn Harrison

Undergraduate Honors Theses

This thesis explores the impact of prenatal polysubstance exposure, specifically focusing on the need for pharmacological treatment for Neonatal Abstinence Syndrome (NAS) and the duration of their hospital stay. A retrospective analysis of 462 infants, including 121 exposed to polysubstances during pregnancy, showed significant associations between polysubstance exposure and adverse neonatal outcomes. Infants with prenatal polysubstance exposure were more likely to require pharmacological treatment for NAS (52.8%) compared to non-exposed infants (38.7%), as determined by chi-square analysis (χ²(1, N = 462) = 7.36, p = .007). Additionally, infants exposed to polysubstances experienced longer hospital stays on average (M = 14.88 …

Understanding The Role Of Sabp2-Interacting Proteins Sip432: A Premnaspirodiene Oxygenase Enzyme In Stress Signaling, Cristiana F. Martinez

Undergraduate Honors Theses

This study focuses on the characterization of a SABP2-interacting protein (SIP)-432. SIP432 is a putative premnaspirodiene oxygenase-like P450 enzyme. Premnaspirodiene is a 15-carbon compound that can be converted into antimicrobial compounds by a hydroxylation reaction. The interaction of SIP432 with SABP2, a critical component of salicylic acid-mediated plant immunity, implies a role for SIP432 in plant stress signaling. This study uses the T-DNA knockout mutant of Arabidopsis thaliana SIP432 (homolog of NtSIP432) to help understand its role in abiotic and biotic stress responses. Plants were subjected to abiotic and biotic stress to understand their role in stress response pathways. Gene …
