Impact Of Diabetes Self-Management Education On Hemoglobin A1c Levels In The Rural Patient Population, Barbara Adomakomensah Sarpong

Electronic Theses and Dissertations

The global prevalence of type 2 diabetes is one of the greatest health threats in society, especially in the rural population. Rural healthcare data analysis has proved a need for type 2 diabetes control education. Despite the existence of helpful diabetes control interventions, rural diabetes patients still struggle to maintain healthy behaviors, with about 60% of the patients recording hemoglobin A1c levels above 9. Many suffer severe conditions (e.g., stroke, kidney failure, and heart attacks) because of poor management of the condition. The project examined the impact of diabetes self-management education on hemoglobin A1c levels in the rural patient population. …

Unraveling The Role Of Hid-1: Insights Into Sgii Regulation, Breanna L. Sellers

Electronic Theses and Dissertations

The regulated secretory pathway is important for the secretion of hormones and neuropeptides from large dense core vesicles (LDCVs). Dysregulation of the biogenesis of LDCVs can result in metabolic and neurological diseases. Recent studies have suggested that the peripheral membrane protein HID-1 plays a role in the sorting and storage of granins which contribute to LDCV biogenesis. To further understand how HID-1 influences the regulation of granins, we investigated potential HID-1 interactors. We determined that while HID-1 is likely functioning in the same pathway as USP25, a deubiquitinating enzyme (DUB), the cause of reduced cellular SgII levels is likely not …

Service-Learning: A Key To Effective Communication For Radiologic Sciences Students, Chelsea Palmer Stephens

Electronic Theses and Dissertations

Many healthcare entities across the globe are moving away from the idea of only treating patients’ diseases to a model of focusing on the overall well-being of patients. Because of this change, healthcare academia must also focus on this change when helping educate clinical practitioners. One major proponent of this type of care is effective communication between the practitioner and the patient. In order to help students grow in this vital attribute, educators must think outside the normal realm of academia and incorporate experiential learning strategies. One method that is often used to place students in an active environment with …

Successful Aging And Turnover Intention Among Older Hospitality Frontline Employees, Thamsanqa Jongile

Electronic Theses and Dissertations

This two-part dissertation delves into the intertwined precursors of successful aging and turnover intent in the hospitality sector. The first part applies a structural equation model to examine the link between perceived narcissistic leadership, successful aging, and turnover intentions. The author posits that work engagement, employee cynicism, and emotional fatigue are the mechanisms through which perceived narcissistic leadership affects successful aging and turnover intent. The findings affirm these conjectures, revealing that narcissistic leadership serves as a predictor of successful aging and turnover intent.

The second manuscript probes further into the antecedents of successful aging, evaluating a theoretical model in which …

Repetition And Retracing In Aphasia Across Discourse Types, Emily Anna Culbertson

Electronic Theses and Dissertations

Purpose: Fluency is an important criterion to classify subtypes of aphasia. Previous studies have discussed the factors of fluency using various speech-language aspects. However, limited research investigated how much lexical hesitations (i.e., repetitions and retraces) are produced in people with aphasia. Lexical hesitations are important indicators of word finding difficulty and self-error detection skills which may be mediated by cognitive-linguistic demands across different discourse tasks. Therefore, the purpose of this study was to examine the lexical hesitations production in people with fluent and non-fluent aphasia compared to neurologically intact adults in various discourse tasks.Method: Three groups of people with fluent …
