The Health Care Commons: A Philosophical Approach, Roel Feys

Theses and Dissertations

This project is the first large-scale and systematic effort to bridge the fields of commons research and biomedical ethics, with the aim of furthering key debates in both areas of inquiry. The aims and contributions of the project are twofold.

First, I argue that commons research is valuable to bioethics, because it provides a language to talk about health care institutions. I critically discuss commons research’s main conceptual tools in the context of health care: the Institutional Analysis and Development (IAD) framework, the design principles of successful commons, parallel experimentation, and polycentric governance regimes. This conceptual apparatus can help to …

Factors That Influence Screening, Brief Intervention, And Referral To Treatment (Sbirt) Implementation In Non-Medical Settings, Andrew Joseph Flaherty

Theses and Dissertations

Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidenced-based intervention model designed to reduce substance use. While initially used in a variety of medical settings, SBIRT is increasingly implemented in non-medical settings. Unfortunately, very little is known about SBIRT implementation in non-medical settings. Therefore, the purpose of this exploratory qualitative study is to understand if professionals recently trained in SBIRT are using it and factors that influence implementation of SBIRT from their perspective.

In-depth qualitative interviews were conducted using a purposive sampling frame, comprised of practitioners recently trained in SBIRT. Interviews were recorded, and then transcribed verbatim, transcripts …

African American Teachers’ Perspectives On Principals’ Leadership Styles And The Influence On Teacher Morale, Ernestine Young

Theses and Dissertations

Morale is a concept that denotes how workers feel about their work and the environment in which they work (Robbins, 2003). Low teacher morale is not a new problem; however, with increasing frequency of low morale, teachers are affected all over the nation because of the financial and academic toll it has on education. Low morale typically impedes the achievement of the organization’s desired outcome and corresponds with unresolved grievances, attrition, and high absenteeism. Low morale is associated with billions of dollars spent per year. Low morale is due to effects such as stress, teacher burnout, absenteeism, attrition, and small …

Examination Of Daily Steps In People With Parkinson’S Disease & Stroke: Two Steps Forward, Reed Handlery

Theses and Dissertations

Despite the well-known health benefits associated with physical activity (PA), the majority of people with Parkinson’s disease (pwPD) and people with stroke do not meet national PA guidelines. As a result, these two groups of people are at increased risk for development of cardiovascular disease, additional disability and death.

Walking as a mode of PA has been shown to improve the health of both pwPD and people with stroke. In fact, a step count of >6000 steps per day is related to a decreased risk of subsequent cardiovascular events in people with stroke. Daily walking is also strongly recommended by …

Research has established both the importance of integrating technology in English language learning and of properly training teachers in order to integrate technology effectively. Inadequate teacher and learner training prevent technology from being utilized to its fullest potential in the English language classroom. A portion of the problem is due to lack of training for practicing teachers. While this is true for English as a second language teachers in all contexts, there is a strong need for instructors working with adult learners to utilize technology and be properly trained in technology integration. Professional development is a way to overcome barriers …

A Comparative Study Of Cannabinoids & Cb1 Receptor Gi Signaling, Haley Kristen Andersen

Theses and Dissertations

The legalization of medical marijuana has highlighted cannabinoids as a potential, opioid-free therapeutic option for pain management; however, the rise in illicit synthetic cannabinoid-induced toxicity has demonstrated the need to outline cannabinoid molecular signaling. The cannabinoid-type 1 (CB1) receptor is an endogenous G protein-gated receptor (GPCR), well-expressed in the central nervous system (CNS) associated with modulating neuronal activity. Cannabinoid agonists bind to the CB1 receptor resulting in the inhibitory G protein (Gi) complex to dissociate into two subunits, Gβγi and Gαi. The Gαi subunit inhibits adenylyl cyclase, leading to a decrease in cyclic adenosine monophosphate (cAMP). The Gβγi subunit activates …

Games And Play Of Dream Of The Red Chamber, Jiayao Wang

Theses and Dissertations

My dissertation examines the games derived from Cao Xueqin’s novel Dream of The Red Chamber during the late nineteenth and early twentieth centuries (1880s-1920s) through its various literary and textual representations. In brief, the games create a sense of otherworldliness for players to imagine their mode of being in a space that is set apart from the daily grinds of the historical transition. Dramatic and literary sources have been a constant motif or theme for traditional games in China. However, it was after the publication of Dream of Red Chamber that the characters, the themes and motifs of the novel …

Distinguishing Neuro-Markers Of Math Learning Disability Using Eeg Coherence, Jessica C. Luedke

Theses and Dissertations

Math learning disability (MLD) is a neurodevelopmental disorder that results from specific cognitive deficits involved with numeric computation and arithmetic that cannot be attributed to low general ability. Although MLD has a significant impact on life outcomes, only a few studies have evaluated unique neurological profile differences between those with and without specific math deficits. EEG coherence has been useful for evaluating neural disconnections in children with neurodevelopmental disorders but has never been used to explain cognitive deficits found in children with MLD. The current study contributed to the literature by evaluating at-rest electrocortical signatures in those with MLD (n …

Methods For Dynamic Stabilization, Performance Improvement, And Load Power Sharing In Dc Power Distribution Systems, Hessamaldin Abdollahi

Theses and Dissertations

Modern DC power distribution systems (DC-PDS) offer high efficiency and flexibility which make them ideal for mission-critical applications such as on-board power systems of All-Electric ships, electric vehicles, More-Electric-Aircrafts, and DC Microgrids.

Sleep Quality And The Prospective Pain-Fatigue Relationship Among Youth With Sickle Cell Disease, Julia D. Johnston

Theses and Dissertations

Youth with sickle cell disease (SCD) are at increased risk for poor psychosocial and functional outcomes due, in part, to disease effects like vaso-occlusive pain crises, fatigue, and poor sleep quality (Brown, 2006). A growing body of literature has examined temporal associations between pain, sleep quality, and mood using daily diary studies (Valrie, Gil, Redding-Lallinger, & Daeschner, 2007a; Valrie et al., 2019). These studies help to identify how symptoms are prospectively related to each other, but they are often limited to small sample sizes and may lack generalizability. Additionally, despite ubiquitous reports of fatigue among sickle cell patients, few studies …

To inform efforts for improving EBT accessibility, the current study characterizes the delivery of engagement practices from the literature within the context of EBT implementation, and examines provider integrity of engagement practice use according to two information sources (i.e., the provider’s EBT training history and …

The Effects Of Super-Resolution Microscopy On Colocalization Conclusions Previously Made With Diffraction-Limited Systems In The Biomedical Sciences, Madison Emily Yemc

Theses and Dissertations

Super-resolution microscopy, also known as nanoscopy, is now established in the field of microscopy. The evolution of super-resolution microscopy techniques has allowed many scientists to peer past the most significant limitation in conventional fluorescence microscopy – the diffraction limit. Super-resolution microscopy systems are able to resolve two points that are less than 250 nm apart, which supersedes the resolution of diffraction limited systems. Colocalization studies are frequently used in the biomedical sciences to measure the close physical association and functional interaction of two biological structures. Previous colocalization conclusions made with conventional fluorescence microscopy are largely based on how the colors …

Steady-State And Transient Study Of Flow Boiling In Microchannels With Microgrooves/Micronozzles, Congcong Ren

Theses and Dissertations

Microchannel flow boiling is one of the most desired cooling solutions for high power electronics. Owing to the high latent heat of vaporization, high heat fluxes can be achieved through phase-change heat transfer. However, the enhancements of (critical heat flux) CHF and heat transfer coefficient (HTC) are usually inhibited by the transitional flow patterns, which highly influence the liquid rewetting. In the past two decades, many techniques have been explored to enhance the liquid rewetting in microscale.

In this dissertation, four parallel micro-grooves fabricated on the bottom of five microchannels (W=200 μm, H=250 μm, L=10 mm) were designed to promote …

Liberalization First, Democratization Later: The Linkage Between Income Inequality, Economic Development, And Democratization, Yi-Tzu Lin

Theses and Dissertations

This dissertation proposes a model of two-stage process of democratization. In the first stage, income inequality is associated with political liberalization, but this association is conditional on economic development. In the second stage, political liberalization is associated with democratization. By looking at 125 authoritarian regimes from 1960 to 2010, I find that in rich countries, high income inequality is associated with low political liberalization, which may stabilize autocratic regimes; while low income inequality is associated with high political liberalization. In poor countries, high income inequality is associated with political liberalization, while low inequality has no effect.

In the second stage, …

Hunter-Gatherer Behavior At Dorn Levee #1 (38fa608): An Analysis Of Lithic Assemblage Formation At A South Carolina Piedmont Site, Robert Altom Cesarini Lyerly

Theses and Dissertations

The site of Dorn Levee #1 (38FA608) in the South Carolina Piedmont has the potential to provide unique information regarding the behaviors and activities of the hunter-gatherer populations who inhabited it throughout prehistory. The Late and Terminal Archaic Period landscape in the Southeast saw with it many major changes in hunter-gatherer lifeways that had begun initial development in periods prior. The continued use of Dorn Levee #1 suggests that it was highly important for these hunter-gatherers, and an analysis of their mobility patterns and general behaviors through the associated lithic debitage material can assist in illuminating its role within a …

Use Of Geospatial Technique To Estimate Traffic Volume On South Carolina Roads, Ryan Andrew Devine

Theses and Dissertations

Data from the Federal Highway Administration (FHWA) indicates that there is an increase in the number of vehicles on already congested roadways. For a department of transportation (DOT) to keep up with this increased demand, it is necessary for them to continuously collect and monitor traffic volume on the roads they maintain. One of the most important parameters that DOTs collect and use for traffic engineering and transportation planning studies is annual average daily traffic (AADT). The DOTs are also required to collect and report AADTs to the Federal Highway Administration annually as part of the Highway Performance Monitoring System …
