The Effect Of Acute Hypoxia Exposure, With Exercise, On Bone Metabolic Biomarkers, Alyssa Bailly

Health, Exercise, and Sports Sciences ETDs

Hypoxic environments, resulting from decreased atmospheric partial pressure of oxygen, reduce oxygen availability in the blood and tissues, leading to a mismatch between supply and demand. This elicits several physiological adaptations and may influence bone metabolism. Although evidence suggests that hypoxia can modulate bone remodeling through hypoxia-inducible pathways, findings remain mixed, with most data derived from chronic hypoxic exposures in animal and cell culture models. Exercise, an essential stimulus for bone health, may exacerbate hypoxic stress; however, the skeletal response to acute hypoxic exposure combined with exercise remains unclear. We propose that intermittent exercise in hypoxia may increase negative markers …

Improving Health Literacy And Self-Management In Adults With Heart Failure: A Nurse-Led Virtual Intervention In Outpatient Support Groups, Vivian Efosa Osunde

Doctoral Projects

Heart failure is a leading cause of morbidity and hospital readmissions, with limited health literacy contributing to poor self‑management and adherence challenges. The purpose of this Doctor of Nursing Practice project was to evaluate the feasibility and preliminary outcomes of a nurse‑led, virtual education-intervention designed to improve health literacy, self‑care behaviors, and medication adherence among adults with chronic heart failure who participate in an outpatient support group. A quality improvement design was used. Convenience sampling yielded nine adult participants with a documented diagnosis of chronic heart failure who attended at least one virtual support group session. The intervention consisted of …

The Formation Of Indian Health Services Within Imperial And Settler-Colonial Contexts, Jillian E. Grisel

American Studies ETDs

This dissertation examines the Indian Health Services as a Cold War biosecurity apparatus, showing how infectious disease was weaponized to dismantle treaty obligations, reorganize tribal lands into “service areas,” and reclassify Indigenous nations as surveilled populations. Against this carceral health economy, Indigenous nations refused. From the 1969 Alcatraz occupation to the 1976 Puyallup takeover of Cushman Indian Hospital, Native activists reclaimed health facilities as sovereign spaces, insisting that care is not a discretionary service but a treaty right grounded in land and kinship. Methodologically, I combine historical-legal analysis of congressional debates, Public Health Service reports, and IHS data with counter-archives …

From Skilled Labor Pipeline To College-Prep Track: A Study Of Admissions, Access, And Intent In A Massachusetts Vocational High School, Jennifer Ferland

Educational Studies Dissertations

This mixed methods study examined the effectiveness and equity of vocational high school admissions in Massachusetts, focusing on an oversubscribed regional vocational high school and its largest urban comprehensive feeder school. Although vocational schools were created to provide equitable, high‑quality career and technical education, and to prepare students for skilled employment, most vocational students now pursue postsecondary academic pathways, contributing to shortages in the trades. At the same time, traditional admissions criteria—focused on grades, attendance, and behavior—have historically limited access for English Learners, students with disabilities, low‑income students, and students of color. The purpose of this study was to investigate …

Conflict, Climate, And Child Health: Evidence From Sub-Saharan Africa, Brian C. Thiede, Nigel C. James

Health Studies Faculty Publications

Many parts of the world are experiencing social and political instability, as well as ongoing climatic changes that are expected to accelerate in the years ahead. These changes can undermine children's health through multiple pathways, and the growing frequency of sociopolitical and environmental stressors increases the likelihood that individuals are exposed to multiple risks simultaneously. Few studies have quantified the effects of such concurrent shocks despite conceptual motivations for doing so. We address this gap by measuring the independent and compounding effects of conflict and climate exposures on the weight-for-height of 0–23 month-old children across 32 countries in sub-Saharan Africa. …

Assessing Legacy Collections: Analyzing The Preservation, Recovery, And Interpretive Value Of Archaeobotanical Remains From Site 15le70 (Pine Crest Rockshelter), Lee County, Kentucky, Jennifer Carroll

Graduate Final Projects

This paper uses the archaeobotanical assemblage from Site 15Le70, a multi-excavated and extensively looted rockshelter in eastern Kentucky, while opening new lines of inquiry into gendered labor and practice during the Archaic-Woodland transition. Because legacy collections are often dispersed across institutions and/or research projects, the materials from any single site may be fragmented, as was the case for 15Le70. Such collections can be overlooked, yet this investigation into 15Le70’s archaeobotanical assemblage demonstrates that partial or scattered datasets can yield meaningful results and hold the potential to fill gaps in the archaeological record left by looting.

In this study, a small …
