A Constructivist Grounded Theory Exploration Of Intergenerational Trauma Among Lgbtq+ Bipoc Individuals, Satveer Kler

Dissertations

Many scholars have argued that existing conceptualizations of trauma such as the Diagnostic and Statistical Manual of Mental Disorders (5th Ed.; DSM-5) conceptualization are inapplicable for individuals of marginalized communities. Individuals of marginalized communities may experience historical trauma, racial trauma, identity-related trauma, or collective trauma. Moreover, the effects of these forms of trauma may persist throughout different generations via biological transmission (e.g., epigenetics) or via interpersonal transmission (e.g., emotion socialization, cultural socialization, attachment, communication styles, behavioral socialization). The generational effects of these forms of trauma are referred to as intergenerational trauma. There has been a paucity of empirical explorations of …

Reconceiving Virtue: A Mengzian Adaptation Of Eudaimonic Virtue Ethics In Response To Contemporary Criticisms, Gina Elizabeth Lebkuecher

Dissertations

The primary question my dissertation aims to answer is: how might eudaimonic virtue ethics be reimagined to respond to contemporary criticisms from disability scholars, feminists, and empirical psychology? To answer this, I introduce the Eudaimonic View of Virtue, or EV, and propose a Mengzian adaptation of the EV (EV-M) in response to these criticisms. The EV captures the four core claims to which eudaimonic virtue ethical theories are committed: (i) virtues, in the sense of excellent character traits or dispositions, are the foundation of ethics or ethical action (i.e., aretaicism); (ii) virtue is at least partially constitutive of human well-being/flourishing …

Christotechtonics: Dildonic Prostheticity In Theological Formulation, Evan Taylor Marsolek

Dissertations

This dissertation asserts the following claim: Christ is a dildo. This project brings Paul B. Preciado into conversations with contemporary philosophies of religion and interrogates a hegemonic Christian theological political matrix. This project articulates a hermeneutic of christotechtonics, which studies appearance, formation, and utilization of Christ. This project is twofold. It begins with a transdisciplinary exploration that entangles queer and trans theories, religious studies, secular studies, and philosophy of religion to position reading queer and trans theories as forms of counter political theologies. The work then transitions into dildonic prostheticity in theological formulation. The 2019 Vatican document “Male and Female …

Understanding Political Rigidity: Exploring The Epistemic Underpinnings Of Political Ideology, Chad Mitchel Osteen

Dissertations

The ideology as motivated social cognition model conceptualizes conservatism in terms of two unique constructs: political conservatism and psychological conservatism. The former pertains to a predisposition to specific ideological beliefs (e.g., resistance to change), while the latter pertains to the psychological traits that are associated with particular ideologies (e.g., negativity bias). Experimental research demonstrates the mechanistic relationship of epistemic motivations and emergent political behavior. Much of the evidence lies in explicitly ideological outcomes. The current proposal seeks to test the fundamental assumption in this body of work. This is the assumption that increased epistemic motivation should lead to a preference …
