Latino medical students represent 7.1% of all entering medical students across all U.S. medical schools. While they represent the largest ethnic minority in the United States within parity lack representation among the physician workforce [sic]. There is a dearth of knowledge of what factors contribute to the success of Latino medical students progressing in …

Cementation And Groundwater Chemistry In Pleistocene Paleodune Deposits Of The Central Oregon Coast, Adrienne Lynn Stephens

Dissertations and Theses

Pleistocene paleodune deposits occur along the Oregon coast, underlying coastal towns, roadways, and associated power and water infrastructure(s). Secondary cementation within these deposits provides some stability, allowing for near-vertical sea cliffs and roadcut outcrops. Yet, slope instability is a prevalent hazard observed within the paleodune deposits. Weakening of cementing agents via changes to groundwater conditions due to altered vegetation, climate change, or contamination, for example, could promote slope instability, threatening lives and infrastructure. This study aims to investigate the variability in the type and degree of cementation and to determine how they are affected by changes in groundwater conditions.

Redeeming Femininity: A Steinian Catholic Feminist Reading Of Flannery O'Connor's Short Fiction, Amanda Pugh

Dissertations and Theses

By situating an analysis of Flannery O’Connor’s short fiction in conversation with Edith Stein’s theology of gender, this project contributes to the critical conversation that interprets O’Connor’s fiction through various feminist frameworks. I respond by proposing an alternative feminist framework that centers O’Connor’s sacramental or incarnational vision of the human body and her characters’ movement from fallenness to redemption. Stein’s theology posits that men and women live their fallenness and redemption in differentiated ways that correspond to their embodied masculinity and femininity, respectively. For men, participating in redemption involves imitating the sacrificial love of Christ’s crucifixion. For women, participating in …
