The Enchantment And Disenchantment Of The Virgin Mary From Late Middle Ages Through The Reformation, Quentin Jameson

Theses and Dissertations

This thesis analyzes the Virgin Mary’s role in late medieval and early modern high magic, arguing that her presence and absence in magic display cases of enchantment and disenchantment. Starting in the twelfth century, debates on Mary’s immaculate conception and purity gradually reshaped and elevated her status in Latin Christendom. This enabled Mary to be an active agent within magic as a purifier and advocate. However, early modern natural philosophers and leaders of the Reformation removed these divine abilities from Mary, producing a disenchanted Virgin within high forms of magic.

This thesis applies Karen Barad’s concept of intra-activity and continuous …

A Dynamical Systems Analysis Of Amyloid-Beta Production, Caroline Lloyd

Theses and Dissertations

Alzheimer’s disease is characterized by the presence of beta-amyloid (A𝛽) plaques in the brain, caused by an accumulation of misfolded A𝛽 proteins. Research suggests that hallmark proteins involved in neurodegenerative disorders such as Alzheimer’s disease, Parkinson’s disease, and Amyotrophic Lateral Sclerosis (ALS) exhibit prion- like behavior. This means that the misfolded, pathogenic proteins influence non- pathogenic proteins to misfold. There is also a small rate of spontaneous conversion which causes A𝛽 to misfold without the presence of pathogenic proteins. Additionally, events that limit blood flow to the brain, such as strokes or direct trauma, are known to increase A𝛽 in …

The Secondary City: Georgetown And The Waccamaw Neck Within A Global Maritime Perspective, 1740-1850, John Paden Wilson

Theses and Dissertations

Georgetown is not and has never been the primary city on the South Carolina coast. Its harbor is shallow and muddy and its urban development lacks the commercial density found in more prominent Atlantic port cities such as New York, Boston, Philadelphia, and Charleston. Despite all indicators to the contrary, this marshy backwater outpost became the second richest port in the United States prior to 1850 through rice and indigo exportation. As a result, the port drew people, goods, and ideas from around the Atlantic. Despite its small size and limited cultural relevance, Georgetown was a regional node for international …

The Role Of Parenting Factors On Moderating The Effects Of Parent Perceived Stress On Waist Circumference And Family Mealtime Outcomes In Black Adolescents With Overweight And Obesity, Taylor Ryan White

Theses and Dissertations

Family mealtime is a protective factor for adolescent health outcomes (e.g. well-being, diet quality); however, parent stress may diminish the frequency and quality of family meals and increase obesity risk through physiological (e.g., allostatic load) and behavioral (e.g., decreased physical activity (PA), obesogenic diet) pathways. Parenting factors, like responsive parenting (e.g., providing support for adolescent healthy eating) and feeding practices (e.g., parental monitoring - tracking adolescent diet), may mitigate the effects of parent stress by promoting adolescent behaviors (e.g., nutritious eating, increased PA) that are linked with healthier weight outcomes; however, few studies have examined this in Black families. Therefore, …
