Biomaterial-Induced Osteogenesis Of Mesenchymal Stem Cells By Surface Roughness And Functionalization, Pongkwan Sitasuwan

Theses and Dissertations

For tissue engineering and regenerative medicine, it is important to understand factors directing the stem cell fate, including self-renewal, proliferation, differentiation, and apoptosis. Bone marrow derived mesenchymal stem cells (BMSCs) have the potential to differentiate into osteoblasts, chondrocytes, adipocytes, and smooth muscle cells. Specifically, in the field of bone tissue engineering, BMSCs are commonly used for in vitro osteogenesis studies. However the mechanisms and signaling pathways that these cells recognize material surface and utilize to differentiate are still unclear. This dissertation focuses on investigating the effect of surface nanotopography and functionalization on the promotion of osteogenic differentiation of BMSCs. Surface …

Building Resiliency: Supporting Elementary School Students Through Parental Bereavement, Sandra Kerr Ray

Theses and Dissertations

This study employed qualitative methods to learn what understandings, practices, and interventions were used by educators from one elementary school to support bereaved children in the classroom and as members of a school community. Educators reported uncertainty about how children grieve, how to talk with children about a deceased parent, how to talk with the bereaved child’s peers about parental death, and how to balance the bereaved child’s emotional and academic needs. Educators were also uncertain about how to recognize and intervene when a parental death was remote in time and the child’s grief response was attenuated (e.g., anxiety, disengagement, …

Deconstructing Books, Reconstructing Women, Summers Esther Morris

Theses and Dissertations

The goal of my thesis project is to examine the notion of choice encountered by females with respect to gender roles. I intend to underscore the turmoil which often comes from choices that leave many classic feminine roles left unattended by either sex. I have created three altered books that address these struggles, as I have personally experienced these, regarding marriage, motherhood, and domesticity. Each book analyzes the conflicting nature of choice and, according to my own decisions as a modern feminist, concludes accordingly. This in-depth look at the struggle for women to not only choose gender roles to adopt, …

Egocentric Biases In Consumer Judgment Of Products With And Without Target Market Labels, David Norton

Theses and Dissertations

Consumer research to date has posited that if we are cued to think of others, then we are likely to be influenced by the type of others we consider. Thus, research on product evaluations has focused on motivational accounts of either favoring or disfavoring a product contingent upon which specific reference group the product is associated with. In this dissertation I advance the theory that product evaluations are also cognitive in nature. Due to egocentric biases of self availability and self positivity I propose that the cueing of an 'other' lowers the valence of thoughts available (relative to thoughts of …

Effect Of Physiological Oxygen Levels On Osteogenic Differentiation Of Adipose-Derived Stem Cells, Suchit Sahai

Theses and Dissertations

Regenerative medicine presents exciting strategies for healing critical-size bone defects through the implantation of cells and biocompatible scaffolds. Most in vitro studies are performed in atmospheric oxygen conditions (~20%), which do not accurately mimic the CSD microenvironment. Due to damage to the vasculature at CSDs, oxygen levels fall into the hypoxic range (<5%), which can impact viability, proliferation and differentiation of the cells employed for bone regeneration. Understanding the cellular responses to hypoxia has grown primarily from study of individual molecular factors. The master regulator of adaptive responses to low oxygen availability is the nuclear factor, hypoxia-inducible factor-1. HIF-1 is a heterodimeric protein, stable below 6% O2 condition in the nucleus and has been shown to play a role in angiogenic-osteogenic coupling. We have developed a responsive, fluorescent, hypoxia detection system and determined whether HIF activity can be tracked in both 2-D and 3-D cultures. Adipose-derived stem cells (ASCs) were selected due to their broad utilization in tissue engineering strategies and characterized the influence of HIF signaling on its phenotype. The work done identified that of hypoxia impaired osteogenic differentiation of ASCs in both 2-D and 3-D cultures and HIF-1 did not mediate this effect. Ischemic preconditioning (IPC) strategy and varied protocols used represents a clinically feasible manipulation of cell preparation to help the survival of implanted ASCs and accelerate osteogenic differentiation at physiological oxygen levels.

Theoretical Investigation Of The Water-Gas Shift Reaction At The Three Phase Boundary Of Ceria Supported Platinum Metal Clusters, Sara Aranifard

Theses and Dissertations

The Water-Gas Shift (WGS: CO+H2O→CO2+H2) reaction is a key step in hydrogen fuel processing for mobile fuel cell applications. Since the reaction is equilibrium-limited and exothermic, high conversions are favored by low temperatures. However, conventional low-temperature shift catalysts are not active enough. Reducible oxide supported small noble metal clusters have shown excellent activity as low temperature WGS catalysts and it is generally believed that these catalysts are bifunctional. In other words, the reaction occurs at the three-phase boundary (TPB) of the noble metal, the reducible oxide, and the gas phase. The small noble metal cluster adsorbs/activates the CO molecules and …

New Bimetallic Iridium Cluster Carbonyl Complexes, Mingwei Chen

Theses and Dissertations

Platinum group metal derived bimetallic clusters have been used as precursors to nanoscale catalysts which have been proven to be more effective than their monometallic counterparts. Iridium is a platinum group metal and its applications in catalysis continue to grow. To take advantages of synergies between mixed-metals, we modified iridium clusters with other metal ligands like tin, germanium, and group IB (gold, silver, copper) etc. and obtained a fairly large amount of new iridium derived bimetallic clusters which could be precursors to catalysts with superior properties than that available nowadays. The reaction of Ir4(CO)12 with Ph3SnOH in the presence of …

The Rhetorical Event Of Modern Southern Humor: "A Requisite Element In Discourse", David Allen Wright

Theses and Dissertations

This dissertation examines the rhetorical nature and dynamics of Southern humor in the second half of the twentieth century by analyzing, from a distinctly rhetorical perspective, a selection of popular Southern humor texts. It seeks to understand how Southern humor happens--its methods and techniques--and it also seeks to understand, as much as possible, the implications of these events for the various interlocutors and participants involved. By investigating the stylistic, storytelling, and linguistic techniques of Southern humor, while relying on the scholarship of writers in a variety of academic disciplines, I hope to answer the following research question: how does Southern …

Measuring Organizational Member Involvement In Physical Activity Coalitions Across The United States, Daniel Benjamin Bornstein

Theses and Dissertations

Physical inactivity has been labeled a global pandemic with enormous economic, social, environmental, and public health consequences. The vast majority of American adults and youth are insufficiently physically active. Increasing population-levels of physical activity (PA) requires broad social and environmental change. PA coalitions provide the structure through which such broad change can be achieved. An extensive literature on health-based coalitions suggests that coalition success is impacted by coalition members. Coalitions are generally comprised of member organizations. Little is known about the characteristics of PA coalitions and less is known about organizational member involvement in PA coalitions. The purpose of this …

Exploring The Role Of Culture And Race In Stroke Rehabilitation Disparities, Jennifaye Verdina Greene

Theses and Dissertations

A study found that racial differences exist in stroke rehabilitation care and outcomes between African Americans (AAs) and Caucasian Americans (CAs). In addition to health status, the rehabilitation care of AAs with stroke (AAwS) may be influenced by cultural and or racial similarities or differences that exist between themselves and their physical therapists (PTs). Distorted perceptions of culture and race in the patient-PT relationship may contribute to disparities in stroke rehabilitation care and outcomes for AAwS. Current stroke rehabilitation literature lacks qualitative research that examines racialized differences in treatment. The purpose of this qualitative exploratory research study was to investigate …

The Parasitic Oligarchy? The Elites In Trinidad And Tobago, Alison Mc Letchie

Theses and Dissertations

The existence of an elite class within societies is often a topic of research in the study of inequality of power and influence. Researchers, however, acknowledge that the nature and composition of the elite varies. Trinidad and Tobago, with its colonial history and diverse population has had to confront issues surrounding access to power by various groups within the society. One driving force of the 1970s Black Power Revolution was the practice of color discrimination in the banking industry. Informed by Mills' (1956) elite theory and rooted in Beckford's (1972) economic theory, this project surveys the elite of Trinidad and …

Shifting Landscapes: The Social And Economic Development Of Aqaba, Jordan, Kimberly K. Cavanagh

Theses and Dissertations

In my dissertation, 'Shifting Landscapes: the Social and Economic Development of Aqaba, Jordan', I examine the role of the global in (re)defining the local by considering the anticipated impact of the planned large-scale urban development within Aqaba. I contend that the identities of the citizens change as the city itself undergoes `renovation' through political adjustments, globalization, tourism development, and commercialization. I argue that these transformations provide opportunities of empowerment, albeit often limited, for marginalized populations who attempt to broaden the dominant local identity by taking advantage of new economic opportunities and increasing their agency within the city. This research provides …
