The Moderating Effects Of Self-Compassion On The Relationship Between Shame And Depression In Military Populations, Sarah Foran

College of Graduate Studies: Theses & Dissertations

The U.S. Military has faced a continuous rise in mental health concerns reported by service members and veterans (Currier et al., 2017; Rosenheck & Fontana, 2007). Studies of military personnel have found that up to 15% of service members meet the criteria for experiencing depression (Shen et al., 2012). Often, individuals with military experience face numerous stressors that positively contribute to this experience of depression and feelings of shame (Bradbard et al., 2014; Litz et al., 2009). Military culture (often emphasizing shame related to mental health) has also been found to put military personnel at higher risk of experiencing depression …

The Elite And The Illicit: Women, Power, And History In Cormac Mccarthy’S All The Pretty Horses And Cities Of The Plain, April Trepagnier

College of Graduate Studies: Theses & Dissertations

Much of the discussion concerning female characters in Cormac McCarthy’s oeuvre revolves around assertions of narrative misogyny and subjection resulting from overly reductive criticism based on identity singularity. Had the critics taken this approach with McCarthy’s male characters, there would be little discussion of his work today as they, too, would have appeared as shallow stereotypes. Such readings are of limited interest or usefulness. Rather, when readers pay attention to the richness of the literary craft of McCarthy’s works, it is possible to read his male characters with great complexity. The same treatment, applied to his female characters, reveals precisely …

Does Friend Groups’ Co-Rumination Explain Depression Homophily Among Undergraduate Women's Friendship Groups?, Alyssa D. C. Klas

College of Graduate Studies: Theses & Dissertations

The transition to college is a period known for changes in social support and increases in depression risk. Undergraduate women are particularly vulnerable to developing internalizing symptoms like depression in response to relational stressors and social norm pressures associated with college life. Co-rumination, defined as excessive and ongoing discussion about problems and emotionally distressing topics, both fosters connection and intimacy between friends and increases risk of depressive symptoms. Thus, relationships that are typically seen as buffers from depression may, paradoxically, contribute to risk when support-seeking becomes maladaptive. Most research on co-rumination’s effects is limited to friendship dyads. However, within larger …

Contextual Augmentation In Artificial Intelligence, Emmanuel Joshua Balogun

College of Graduate Studies: Theses & Dissertations

Contextual understanding is a significant challenge of Large Language Models (LLMs), which are typically trained on general-purpose datasets. Due to this, LLMs fail to capture nuanced or domain-specific information and may struggle to interpret user queries accurately. Consequently, prompt engineering can become complex in automating, and LLMs are prone to “hallucinating”—generating random or irrelevant texts—when they lack sufficient context. This undermines their ability to provide focused, accurate responses. Accordingly, this thesis seeks to enhance the contextual understanding capabilities of Artificial Intelligence systems to facilitate more precise and relevant answer generation. Study A looks into a new approach to combating misinformation …

Literary Homeplace As A Site Of Knowing And Healing, Shamonique Hassell

College of Graduate Studies: Theses & Dissertations

The concept of literary homeplace serves as a locus of rhetorical healing for Black women, emphasizing their lived experiences and creative expressions as forms of resistance and restoration (Collins, 1986; hooks, 1990; Nettles, 2001). The labor of Black women within families, churches, and artistic endeavors contributes to the cultivation of a collective consciousness surrounding oppression and healing (Edwards, 2010; Carey, 2016; Morrison, 1992). Building upon hooks’ (1990) notion of homeplace, this dissertation examines how Black women foster spaces characterized by care, dignity, and resilience (Hersey, 2022; Tate, 1984). Using personal narrative and articulating Black women’s voices, I position homeplace as …

A Critical Examination Of Scent Avoidance And Olfactory Development After Neonatal Predator Scent Exposure, Cynthia Ware

College of Graduate Studies: Theses & Dissertations

The long-standing assumption that predator odor avoidance in rodents is an innate survival mechanism has shaped decades of behavioral neuroscience research and underpins translational models of post-traumatic stress disorder (PTSD). However, developmental systems theory (DST) posits that behaviors emerge from dynamic interactions across physiological and environmental systems over time, rather than from fixed genetic programs. This study critically evaluates the developmental plasticity of predator scent aversion by examining whether early-life exposure to red fox urine (a natural predator odor) can attenuate avoidance behaviors in Long–Evans rats. Seventy-one rats were bred into three conditions: Control (no exposure), Partial (exposure from birth), …
