My Risk Or Theirs? An Experimental Investigation Of Character-Driven And Plot-Driven Engagement As Explanations For Risk Perceptions, Emma Cox

All Theses

Two distinct bodies of research examine means of increasing people’s health- related risk perceptions through persuasive message design. First, Construal Level Theory (CLT) posits that reducing perceived psychological distance from a health risk can increase people’s perceived relevance of the health issue. Second, models of narrative persuasion posit that narratives elicit audience engagement, which reduces counter- arguing and increases risk perceptions. So and Nabi’s (2013) Risk Convergence Model (RCM) was proposed to merge the two bodies of research: the model posits that viewers’ engagement with narratives diminishes perceived social distance from characters, resulting in a convergence of risk between characters …

Photobiomodulation Of Bovine Oocytes During Maturation Increases Atp Content And Enhances Subsequent Embryonic Development, Kendall Richey

All Theses

Bovine in-vitro production(IVP) of embryos is a growing field for producing offspring with desirable genetics in the cattle industries. While IVP is effective, oocyte cytoplasmic maturation is compromised, and bovine oocytes matured in-vitro have reduced metabolic activity than those matured in-vivo. Mitochondria are the central unit of oocyte metabolism, producing ATP through OXPHOS. Photobiomodulation is a light treatment reported to improve metabolic activity. In five experiments, we measured the effects of photobiomodulation treatment with red LED at 16-(L-16) and 20 h(L-20) of bovine oocyte in-vitro maturation on subsequent embryonic development, mitochondrial activity and nuclear progression. Bovine COCs were aspirated …

An In Vitro Investigation Of Urothelial Cell Function In Response To Hypoxia And Pressure In Relation To Bladder Outlet Obstruction, Britney Hudson

All Dissertations

Bladder outlet obstruction (BOO) is a prevalent urological condition and can be characterized by the presence of lower urinary tract symptoms (LUTS), such as hesitancy, weak stream, and nocturia. The main cause of BOO is a partial blockage of the urethra, which results in elevated voiding pressure, high storage pressure, and tissue ischemia, which are thought to be the triggers of bladder inflammation and subsequent fibrosis. Often patients do not seek treatment until the conditions get severe. Thus, it would be ideal to have an early diagnostic tool to detect changes in the bladder due to BOO. Extracellular vesicles (EVs) …

Single Cell Pharmacodynamic Modeling Of Cancer Cell Lines, Arnab Mutsuddy

All Dissertations

Cancer is one of the leading causes of disease related death worldwide. Since the discovery of the genomic origins of cancer, targeted therapy has been developed towards specific mutations implicated for oncogenic transformation. However, current standard-of-care for mapping cancer patients to efficacious drug combination is often inadequate. The pathophysiology of tumor progression relies on the dysregulation of biomolecular pathways of which the topology and the dynamics challenge prognosis. Moreover, the overall genomic instability involved in disease states and the resulting inter-patient as well as intra-tumoral heterogeneity challenge rationalization of therapy and clinical decision-making. It highlights the need for the use …

A Rhetorical-Sociological Understanding Of Emotion, Amy Boone

All Dissertations

This project presents a rhetorical-sociological understanding of emotion while foregrounding the place and role of language. Born from Sara Ahmed’s work in The Cultural Politics of Emotion, it presents a simplified equation (contact + orientation = emotion) as both a prescriptive and descriptive formula for making sense of human emotional experience. Starting with an exploration of the difficult-to-understand affect system, this dissertation identifies both rhetoric and affect as energies which cannot be understood apart from their traces, the things they move, produce, and become. As a way to get at these often-invisible forces, two trace studies are conducted which explore …
