Public Influence On Small Wars: Somalia And A Theory Of Constituent Discontent, Barry Smith

Graduate Thesis and Dissertation post-2024

Public opinion predicts American small war sustainment through institutional causal mechanisms of Congress and political-military relations. An increase in general public disapproval (not necessarily connected to a war) predicts the time when Members of Congress look to their constituents for policy changes to appease broad frustration. Constituent discontent toward a U.S. small war is absorbed by individual legislators, translated into legislative constraint, and projected onto the Department of Defense that is highly attentive to Congress. America abandons war aims, despite its military advantage over adversaries, when the ways and means available for military operations are constrained by a threat or …

Using Foucauldian Discourse Analysis (FDA) 25 interviews with individuals who resigned during this period were analyzed to explore how workers engage with neoliberal discourses in making sense of their work-related attitudes, experiences, and decisions as well as the broader discursive constructions used to interpret the Great Resignation as a societal phenomenon. Participants’ narratives reveal varying degrees of alignment, negotiation, and resistance to neoliberal subjectivity, shaped by …

Grief, Identity Transformation, And Resilience In Emerging Adulthood Following Profound Loss, Isabella S. Marcon

Honors Undergraduate Theses

Loss and grief are unfortunate forces of the human experience, highly variable in the experience of intensity and duration, not limited solely to death. Grief is the process that follows loss, and can be a transformative journey towards personal growth, healing, and reshaping one’s self-concept (Corless et al., 2014).

Individuals who have experienced the loss of a significant figure and have grappled with grief and bereavement during their childhood, adolescence, or emerging adulthood have yet to be thoroughly studied. The repercussions of navigating grief and bereavement during these formative years encompass intrapersonal relationships, coping mechanisms, resilience, and overall psychological well-being …

The Influence Of Foster Parent Characteristics On The Relational Permanence Of Foster Youth, Yogita Venkata

Honors Undergraduate Theses

Research suggests that lack of permanency is associated with an increased risk of aggression, mental instability, and delinquent behavior in children (Leve et al., 2012). A crucial component of permanency involves establishing stable connections, including relational permanence with peers and adults, which are believed to enhance the well-being of foster youth (Wekerle et al., 2009). Further, the literature suggests a relationship between a parent’s adverse traumatic experiences, their attachments to their own parents, and their ability to regulate their foster child’s relational permanence to supportive adults and peers. Foster parents who have experienced trauma are often insecurely attached to their …

Madness As Epistemic Advantage: The Relevance Of Standpoint Epistemology To The Evolution Of Mental Health Care, Aven E. Kazmier

Honors Undergraduate Theses

The intent of this thesis is to examine the potential epistemic advantage possessed by those with lived experience of mental illness. The frequent lack of conceptual alignment between the perspectives of individuals with lived experience and the biomedical model of mental illness has often resulted in epistemic injustice—lived experiential knowledge tends to be devalued and excluded from larger discussions about mental health. I propose that by occupying a marginalized social location and critically engaging with one’s social position, psychopathologized individuals may achieve a standpoint that allows a deeper comprehension of the systems of power that affect the mental health care …

The Association Between Patient Race/Ethnicity/Culture, Physician-Patient Communication, And Patient Outcomes: A Systematic Review, Maazen Khan
