External Homophobia And Outness In Gay Men., Thomas Charles Isaak Jr

Electronic Theses and Dissertations

Prior studies regarding outness among gay men have often focused on internalized homophobia as a barrier to coming out for gay men, while less emphasis has been placed on external homophobia. Drawing upon social construction theory and Connell’s hierarchy of masculinity, I utilize data from the 2010 Social Justice Sexuality Project to complete an ordinary least square regression to examine the impact of external homophobia on the level of outness among the 987 gay men in this study. In this study, I find that gay men who were exposed to external homophobia reported decreased levels of outness. Further, I find …

Plasma Resuscitation Attenuates Intestinal Barrier Disturbance Following Hemorrhagic Shock., Jessica E. Schucht

Electronic Theses and Dissertations

Background: Intestinal ischemia-reperfusion injury (IIRI) following resuscitated hemorrhagic shock (HS/RES) leads to endothelial damage, microcirculatory dysfunction and intestinal barrier breakdown, increasing intestinal permeability. This pathologic process contributes pathophysiology of multiple organ dysfunction syndrome (MODS) in some trauma patients. Although vascular smooth muscle machinery remains intact, microvascular vasoconstriction occurs secondary to endothelial cell damage, resulting in further ischemia and organ injury. Used separately, resuscitation with Fresh Frozen Plasma (FFP) or Direct Peritoneal Resuscitation (DPR) improves the intestinal microcirculation and alleviates organ injury. Further examination of these effects individually or combined could aid in the resuscitation of hemorrhagic shock. Methods: Sprague Dawley …

"Don't Put An 'Or' Where God Puts An 'And'": Constitutive Rhetoric In Queer Appalachia., Brooke Elizabeth Boling

Electronic Theses and Dissertations

Appalachians who use the word “queer” to specifically refer to being gay, lesbian, bisexual, transgender, queer, intersex, and/or asexual, are regularly faced with negotiating how these parts of their identity can exist simultaneously, as many both within and without the region believe it is impossible to be Appalachian and queer at the same time. Despite rampant homophobia in the region and external narratives suggesting that queer Appalachians do not exist, these folkx have carved out spaces for themselves to assert their identities and create community and belonging through rhetorical actions. Many of these spaces are online, taking place through digital …

Characterization Of Adiposity And Inflammation Genetic Pleiotropy Underlying Cardiovascular Risk Factors In Hispanics., Mohammad Yaser (Anwar)

Electronic Theses and Dissertations

The observed overlap between genetic variants associated with both adiposity and inflammatory markers suggests that changes in both adiposity and inflammation could be partially mediated by common pathways. The pervasive but sparsely characterized “pleiotropic” genetic variants associated with both adiposity and inflammation have been hypothesized to provide insight into the shared biology. This study explored and characterized the genetic pleiotropy underpinning adiposity and inflammation using genetic and phenotypic observations from the Cameron County Hispanic Cohort (CCHC). A total of 3,313 samples and >9 million single nucleotide polymorphisms (SNPs) were examined in this study. Mixed model genome-wide association studies (GWAS) were …

A Phenomenological Study Of Kindergarten Teachers' Perceptions Of Their Students In The Age Of Kindergarten Readiness., Adam Nelson Stephens

Electronic Theses and Dissertations

Kindergarten has changed dramatically from a play-based, social experience a generation ago to the literacy- and numeracy-based curricula of today. With this shift in academic expectations, children now take a kindergarten readiness assessment at the beginning of the school year to determine their likelihood of success based on their pre-kindergarten preparation. While previous studies have examined teachers’ perceptions of current kindergarten practices, expectations, and students, few use teachers’ descriptions as the data (Abry et al., 2015; Hustedt et al., 2018). This phenomenological study reports how kindergarten teachers at three Central Kentucky elementary schools describe their attitudes about their own kindergarten …

Investigating The Disorder And Compaction Of Designed Minielastin Using Nuclear Magnetic Resonance., Ma Faye Charmagne Aquino Carvajal

Electronic Theses and Dissertations

Minielastins are elastin-based proteins with alternating hydrophobic and cross-link modules similar to tropoelastin. Tropoelastin is the ~70 kDa soluble monomeric precursor of elastin. The extracellular matrix protein, elastin provides elasticity to tissues and organs such as lungs, arteries and ligaments. The elastic properties of natural elastin are believed to be entropic in origin. In vivo, the elastin matrix is approximately 50% water by weight. Without water, elastin is brittle and hard. Minielastins, like tropoelastin, undergo a liquid-liquid phase transition upon an increase in temperature. Factors such as hydrophobicity, chain length and concentration affect the coacervation temperature, T_c. The …

Samuel Daniel’S Lyric Reception: The Role Of Poet-Critics From Wordsworth To Winters, Caleb Mcghee

Electronic Theses and Dissertations

The Elizabethan poet Samuel Daniel was popular in his day, producing lyric, dramatic, and narrative poems. Contemporary anthologies, however, memorialize him primarily as a lyric poet, one that usually gets few entries. My thesis shows how Daniel had a minor reputation as a lyric poet by the 1960’s, despite having high-profile admirers. These well-known poet-critics who engaged with his work are essential to analyzing his lyric reputation: owing to the Romantic emphasis on the lyric, I begin with William Wordsworth and Samuel Taylor Coleridge’s reception of his lyrics in the 19th century. I then analyze the turn of the century …
