Communicating In Crisis: Rhetorical (De)Stabilization During The Covid-19 Pandemic., Brittany Nicole Smart

Electronic Theses and Dissertations

This project explores the role of rhetoric in crisis—how rhetoric can contribute to both the stabilization and destabilization of a worldwide health emergency. Specifically, I utilize the COVID-19 pandemic as a case study to investigate how institutional rhetorics exacerbated the ongoing burnout epidemic amongst healthcare workers. Through a feminist, materialist take on institutional ethnography (Fullagar & Pavlidis, 2021; Griffith & Smith, 2014), I show how, while institutions like the CDC were under pressure to contain the spread of the virus, in the chaos of communicating safety regulations to healthcare professionals, they inadvertently subverted clinician autonomy and expertise by “coordinating” (LaFrance, …

Using A Toxic Aging Coin To Assess Hexavalent Chromium-Induced Neurotoxicity., Samuel Thomas Vielee

Electronic Theses and Dissertations

We are facing an aging crisis, with 20% of the U.S. population projected to be geriatric (65+) by 2030 and live another 40+ years. Age-related diseases accompany a growing geriatric population, emphasizing the need to understand their etiology. Environmental pollutants compound this crisis by: 1) geriatrics are more susceptible, exacerbating age-related diseases and comorbidities, and 2) they accelerate biological aging, inducing age-related diseases at younger ages. We address this crisis using a ‘toxic aging coin’ approach; heads examines how age impacts toxicity, tails examines how chemicals accelerate aging. This thesis applies the heads side for Cr(VI)-induced neurotoxicity across ages. We …

In addition, the EneGate system is presented as a complementary …

From "Smart Talk" To "Living Well": Commonplaces And Their Role In Narratives Of Rare Disease., Caitlin E. Ray

Electronic Theses and Dissertations

As healthcare becomes more complex, automated, and bureaucratic, patients often suffer from a lack of resources, agency, and visibility when seeking medical care. Rhetoric and Composition, specifically the subfield of Rhetoric of Health and Medicine (RHM), is interested in studying and intervening into such issues. One way to challenge our current understanding of healthcare is to consider how the rare disease patient experience reveals the gaps, limitations, and assumptions of illness and health. I argue here that through rare diseases, rhetoricians of health and medicine can better understand the representation, advocacy, and patient experience within healthcare, and potentially lead to …

Investigation Of Heterocyclic Amines And N-Acetyltransferase 2 Genetic Polymorphism In The Dysregulation Of Hepatic Energy Homeostasis: A Gene-Environment Approach., Kennedy M Walls

Electronic Theses and Dissertations

Heterocyclic amines (HCAs) are mutagens generated when cooking meat for prolonged periods of time or until well-done. Recent epidemiological studies reported significant associations between dietary HCA exposure and insulin resistance and type II diabetes. However, no previous studies have examined if HCAs, independent of meat consumption, contributes to pathogenesis of insulin resistance or metabolic disease. It is well known that HCAs require hepatic bioactivation by cytochrome P450 1A2 (CYP1A2) and N-acetyltransferase 2 (NAT2). NAT2 expresses a well-defined genetic polymorphism in humans that, depending on the combination of NAT2 alleles, correlate to rapid, intermediate, or slow acetylator phenotypes that exhibit differential …

A View From Within: Timbre As An Analytical Tool In Contemporary Viola Music, Ash Mach

Electronic Theses and Dissertations

Timbre is an elusive musical parameter that musicians, physicists, and cognitive scientists have been grappling with for centuries. While timbre can roughly be defined as an auditory attribute that distinguishes one tone color from another, this definition does not capture the complexities of sound and our perceptions thereof. Research on timbre has flourished since the 20th century, however, timbre studies has largely gone unnoticed within the viola community. This study, “A View from Within,” helps close the gap between timbre studies and viola repertoire scholarship by presenting analyses of three pieces from the 20th and 21st centuries through a timbre …

Representing The Mixed Plate: Involving Descendant Communities And Kānaka Maoli In Hawai’I Plantation Museums, Amanda Ku’Ualohalanileimakamae Lane

Electronic Theses and Dissertations

This thesis explores the ways that the involvement of diverse stakeholders at Hawai’i plantation museums affects representations of Hawai’i’s plantation history. Plantations in Hawai’i had a direct colonizing effect on Kānaka Maoli (Native Hawaiians), displacing them from their lands, replacing them with immigrant laborers, and putting into motion the chain of events that led to Hawai’i’s annexation in 1898. The current-day population in Hawai’i continues to reflect these significant changes in the society and culture of the islands. Hawai’i’s plantation museums traverse topics of labor, immigration, indentured servitude, and colonization. Simultaneously, these museums advance stories of perseverance, celebration, and multiculturalism. …

Thermo-Mechanical Instabilities In Next-Generation Friction Materials In High-Speed Sliding Systems, Kingsford Koranteng

Electronic Theses and Dissertations

For centuries, the manufacturing industry has incorporated metals like copper into friction materials to enhance thermal properties and minimize thermo-mechanical instabilities (TMI) in high-speed sliding systems. Unfortunately, these metals have adverse environmental effects due to the emission of hazardous particulate matter. As a result, there is a growing movement towards adopting next-generation friction materials as an alternative solution.

The study begins by conducting experimental and numerical investigations to examine the instabilities found in metal-based friction materials. The primary objective is to utilize the insights gained from the investigations to computationally explore effective strategies for mitigating various instabilities that may arise …

Likeness In Utopia: Situation And Metaphor From Thomas More To Edward Bellamy, Sage Rachmiel Bard Gilbert

Electronic Theses and Dissertations

As a literary genre, utopia is notably didactic. It seeks to teach desire and to educate hope. As such, utopia provides a unique site to examine the way metaphor and imagination enable one to be convinced, and the way those same elements facilitate misunderstanding. Following the theorization of Ernst Bloch, the goal of critiquing these literary utopias is not to reject hope but, rather, to educate our own daydreams, to learn and move forward. These chapters examine didacticism and the development of colonial metonymy in Thomas More’s Utopia, the way metaphor operates through time in Edward Bellamy’s Looking Backward: …

The Use Of Regularization To Detect Racial Inequities In Pay Equity Studies: An Empirical Study And Reflections On Regulation Methods, Christopher M. Peña

Electronic Theses and Dissertations

Since the late 1970s, multiple linear regression has been the preferred method for identifying discrimination in pay. An empirical study on this topic was conducted using quantitative critical methods. A literature review first examined conflicting views on using multiple linear regression in pay equity studies. The review found that multiple linear regression is used so prevalently in pay equity studies because the courts and practitioners have widely accepted it and because of its simplicity and ability to parse multiple sources of variance simultaneously. Commentaries in the literature cautioned about errors in model specification, the use of tainted variables, and the …

Enhancing Search Engine Results: A Comparative Study Of Graph And Timeline Visualizations For Semantic And Temporal Relationship Discovery, Muhammad Shahiq Qureshi

Electronic Theses and Dissertations

In today’s digital age, search engines have become indispensable tools for finding information among the corpus of billions of webpages. The standard that most search engines follow is to display search results in a list-based format arranged according to a ranking algorithm. Although this format is good for presenting the most relevant results to users, it fails to represent the underlying relations between different results. These relations, among others, can generally be of either a temporal or semantic nature. A user who wants to explore the results that are connected by those relations would have to make a manual effort …

You Have To Play To Win: Value Capture In Open Innovation, John T. Pritchard

It integrates the dynamic capability view and open innovation literature to build a framework and set of arguments on how knowledge is …

Safest Kid (A Sexual Assault Framework In Education To Support Trauma In Kids With Intellectual Disability): Delphi Study Development Of A Model And Utilization, Ashley M. Hudson

Electronic Theses and Dissertations

There is a grave need for additions to the school psychologist’s toolbox to support students with intellectual disability (ID) and sexual trauma. These children are especially vulnerable to adverse life experiences overall and are at a particularly high risk of experiencing sexual abuse and resulting trauma. Children with ID are less likely to have their trauma symptoms identified by those around them, as symptoms do not always present in the same way as their neurotypical peers and trauma symptoms are more likely to be grouped into the rest of their disability through diagnostic overshadowing. Additionally, individuals with ID are at …

Reevaluating The God-Human Relationship Through The Psychological Origin Of Sin: A Comparative Theology Of Schleiermacher And Kierkegaard On The Doctrine Of Sin, Brandon Tsark

Electronic Theses and Dissertations

In his The Concept of Anxiety, Kierkegaard’s decision to have Haufniensis acknowledge Schleiermacher’s contribution to the doctrine of sin continues to raise questions regarding Schleiermacher’s influence on Kierkegaard’s intellectual development. These questions also serve to underscore the general need to locate Kierkegaard properly within the larger context of religious and theological studies in the nineteenth century. Our project here seeks to address these questions with a comparative theology of Schleiermacher and Kierkegaard on the Christian doctrine of sin. I argue that Kierkegaard is right to credit Schleiermacher as a source of inspiration in The Concept of Anxiety because of …

Material Culture In The Mediterranean: An Exploration And Examination Of Anti-Judaic And Antisemitic Spanish Medieval Cultural History, Madison Elizabeth Tarleton

Electronic Theses and Dissertations

Author Gavin Langmuir produced two monographs during his career, both published in 1990. Across both texts, one a proper monograph and one a compilation of essays, he offers a bifurcation of anti-Judaism and antisemitism. These texts illuminate his definitions of the terms and his differentiations on the basis of reason and rationality. Using the bones of these theories, I propose a different kind of bifurcation of these terms as it relates to Mediterranean (medieval) material culture using a cultural historical lens. By applying Gavin Langmuir's theoretical model of nonrational anti-Judaism and irrational antisemitism to material culture, I argue that visual …
