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 …

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
