Neurochemistry, Physiology, And Behavior In A Model Of Gulf War Illness, Victoria A. Macht

Theses and Dissertations

Upon returning from the first Gulf War, soldiers cited a plethora of unexplained physical and cognitive deficits which have since been termed Gulf War Illness (GWI). Presentation of GWI is positively correlated with pyridostigmine bromide (PB) use, which was prophylactically administered to soldiers in response to threats of chemical warfare. To test the overarching hypothesis that PB interacted with stress of deployment to alter neural, endocrine, and immune systems, the following studies used a 2×2 rodent model with 14 days of drug treatment (vehicle; PB) and 10 days of repeated restraint stress (stressed) or non-stressed-control conditions. Results indicate that PB …

The Ghosts Of Lucy Snowe: Queer Temporality In Villette, Lauren Schuldt

Theses and Dissertations

Though Lucy Snowe has been read as an agent of queer nonconformity and as a master of ambiguity, queer interpretations of Charlotte Brontë’s Villette have remained relatively scarce and limited in scope. This essay examines Lucy Snow’s unique model of queer experience that manifests not only in moments of openly subversive gender performance, homoerotic desire, or sexual identity, but also as an oppositional mode of organizing and articulating her life in terms of time. Using the temporally queer metaphor of the ghost, this essay explores Lucy’s resistance to frameworks of time which structure life narratives through logics of heterosexual development …

Insects As Metaphors For Post-Civil War Reconstruction Of The Civic Body In Augustan Age Rome, Olivia Semler

Theses and Dissertations

Early Augustan Age literature saw a focus on recovery from a period steeped in the tragic losses of civil war; Vergil, in his Georgics, and Ovid, in his Metamorphoses, employed insects likened to, or transformed into, humans as a way to suggest possible models for recovery. While these models have been studied throughout classical scholarship for their value in proposing a new Roman Golden Age and its tenability, scholars have long overlooked the importance of the insects used in such models, and the ways in which they can substantially alter our understanding of these metaphors. As structures for cultural understanding …

Body Mass Index Trajectories And The Relationship Between Stressful Life Changes And Nutrition-Related Health Outcomes Among United States Army Soldiers, Julianna Marie Jayne

Theses and Dissertations

Body mass index (BMI) has risen among members of the military, though to a lesser degree than in civilian populations. BMI as an anthropometric tool has been essential for population surveillance and documenting the obesity epidemic and its health consequences. One use for BMI in population surveillance is to model the BMI trajectories of a population over time. Many studies are available on the BMI trajectories and determinants of BMI in civilians, but few studies of this nature in military populations exist. Establishing the shape and determinants of BMI trajectories among Soldiers is critical given the importance of weight management …

Cortical Damage And Disconnection Contribute To Post-Stroke Sensorimotor Impairment, Shafagh Yazdani

Theses and Dissertations

BACKGROUND. Stroke is a cerebrovascular event that causes permanent damage to brain regions and decreases in connectivity (disconnection) between brain regions. Most stroke survivors have permanent difficulties performing functional motor tasks, thus research into how damage and disconnection produce difficulties performing motor tasks can help guide post-stroke rehabilitation. Previous studies have examined the extent to which cortical damage produces motor impairments, but the extent to which disconnection produces motor impairments remains unclear. Furthermore, studies have focused on how motor impairments contribute to difficulties performing motor tasks, whereas the role of visuospatial impairments has received little attention. Neuroimaging techniques for quantifying …

Implementation Of A Depression Screening Tool For Cardiovascular Patients In The Primary Care Setting, Amber Nicole Ballentine

Theses and Dissertations

Background: Patients with cardiovascular disease (CVD) have a two-fold increased risk of depression as compared to patients without CVD. According to the American Heart Association (AHA, 2016), there is no gold-standard procedure for screening for depression in cardiovascular patients. Screening for depression varies greatly across specialties and practices, often leaving a gap for detection and treatment of depression in cardiac patients. There are many depression screening tools available; however, the AHA recommends use of the patient health questionnaire (PHQ) screening tool. The PHQ-2 and PHQ-9 questionnaires are the most brief, sensitive, and specific depression screening tool for patients with …

Understanding The Impact Of Land Use On Microbial Water Quality To Support Decisions For A Future Land Use Plan, Mohammed Tawfiq Aljassim

Theses and Dissertations

May River meandering through the Town of Bluffton, South Carolina has been known for its high level of water quality. The May River is one of the major sources of shellfish harvesting in South Carolina. Due to the non-point source pollution of fecal coliform, the water quality of the May River became degraded. As a result, shellfish harvesting classification in the May River was downgraded for the first time in its history. The rapid growth of the Town has led to a change in land use, which might be related to the increased levels of fecal coliform in the stream …

Residential Mobility And Enrollment Churn In A Medicaid Population, John E. Stewart

Theses and Dissertations

Previous investigations show high rates of enrollment discontinuity, or churn, among Medicaid participants. Discontinuity of coverage can limit appropriate use of health care, increase emergency department utilization and in-patient hospitalization, negatively affect self-reported health, increase health care spending, and compound Medicaid administrative costs. Efforts to more fully understand and ultimately reduce enrollment churn thus are vital to Medicaid agencies and beneficiaries. Residential moves are life transitions, often marking other significant life events (e.g., changes in employment or family structure) that can alter eligibility for Medicaid benefits. Few studies have examined residential moves among Medicaid members, or considered residential mobility as …

Diction For Mandarin/Chinese Singers: A Methodology To Achieve Resonant Tone And Vowel Unification In Western Choral Music, Chien-Yi Li

Theses and Dissertations

Understanding vowel production is vital in order to develop a rich choral tone based on unified vowels, appropriate resonance, and freely produced singing. Likewise, correct articulation of consonants produces understandable text. Enunciating the texts of Western choral repertoire is often challenging for Mandarin singers, and learning English pronunciation requires a significant amount of rehearsal time. Further, amateur and developing singers in Mandarin-speaking countries often employ a bright sound and lowered soft palate when singing, in common with their native speaking position. Therefore, voice placement, resonance, and vowel modification must be carefully addressed and improved upon when they are singing Western …

Male Gender Equality Ideology, Empathy, And Prosocial Bystanding Behaviors And Intentions: A Path To Intimate Partner Violence Prevention On College Campuses, Virginia Diane Woodbrown

Theses and Dissertations
