Environmental Beliefs Among Evangelical Leadership, Jeffrey Stark

Dissertations

There has been consensus among climate scientists for over a decade about the reality of human caused climate change. Even with this consensus, the public understanding of this issue remains divided based on factors generally unrelated to the science. Evangelical Protestants are one group which consistently polls as more skeptical of climate change. This is true not only when compared to the general population but also when compared to other religious demographics. Most large-scale surveys of evangelicals assume the demographic to be a monolith and do not attempt to break the demographic down further. In this mixed methods study, we …

Cyclical Matters: Black Labor, Temporality, And The Incomplete Reconstructions Within African American Literature, Courtney Walton

Dissertations

This dissertation examines the role literature plays in understanding black life post-reconstruction and post-civil rights movement. Specifically, I explore the continuation of injustices and mistreatment for black workers, the role black labor plays during the first and second post-reconstructions, and how literature can be used in framing this discussion. The similarities between these periods help us to better understand the cycle of racist societal expectations and the challenges black workers face integrating into society, discriminatory mandates required of black workers, the unfair job market, and forced labor. These periods interact cyclically in that the second post-reconstruction models the first post-reconstruction. …

“The Wonderful Swiftness Of The Soul”: Mental Movement And Religious Ethics In Medieval English Literature, Abigail Palmisano

Dissertations

This dissertation analyzes conceptual metaphors of psychological motion and stability in medieval English religious literature. I trace how language itself structures cultural approaches to epistemology, spiritual knowing, and virtue. Chapter One examines Alfred’s translation of Neoplatonic metaphors of psychological movement in the OE translations of The Consolation of Philosophy and Augustine’s Soliloquies. I argue that the reconfiguration of these metaphors into images of stability reveals an epistemology centered on certainty. Chapter Two compares the omission of motive psychological metaphor in Cynewulf’s Juliana and Ælfric’s “St. Agatha and St. Lucy” in process of translation. While Cynewulf’s depiction of virtue through stability …
