Beyond Isolation: The Mississippi Delta In A Global World, Stella D. Lindsey

Electronic Theses and Dissertations

This study examines the paradoxes and complexities of the Mississippi Delta through an international lens. The fundamental premise guiding the research is that goods, people, ideas, technology, and capital cross national borders; therefore, local transformations can only be fully understood within a global context. The study concentrates on the evolution of the reciprocal, complex relationship between the region and the international community, along with the local and global consequences of a series of transnational exchanges. With a primary focus on agribusinesses, the research challenges traditional visions of the Delta as an isolated and provincial region immune to modernization. Instead the …

The Influence Of Chromium Supplementation On The Insulin Pathway, Carcass Traits, And Meat Quality Of Feedlot Steers, Heather Rode

Electronic Theses and Dissertations

Chromium supplementation (Cr) can increase efficiency of growth in livestock by amplifying insulin signaling. Previous research showed Cr increases nutrient utilization and changes in muscle growth and fat deposition. Therefore, the objective of this research was to determine how Cr affects carcass traits, meat quality, and the insulin pathway in feedlot steers. Calf-fed steers were allotted to 0 ppb (CON) or 400 ppb Cr propionate (Cr400) for 210d in experiment 1. Two longissimus muscle (LM) biopsies were collected to examine protein abundance and gene expression after adaptation to a terminal implant and after adaption to ractopamine hydrochloride (RAC). A follow …

Object Of Your Rejection: The Symbolic Annihilation And Recuperation Of Queer Identities In Country Music, Lauren Veline

Electronic Theses and Dissertations

This thesis addresses the double-marginalization of white queers living in Bible Belt communities by examining the symbolic annihilation of queer identities in country music. Bible Belt queers face unique obstacles and have different needs than queer communities elsewhere due to the cultural context of their communities. The urban-centric (“metronormative”) standards of queer identity and visibility presented in the media do not translate to their lived experiences. Moreover, while white, non-urban southerners possess a source of popular-media expression through country music, queer identities are noticeably absent. The invisibility of Bible Belt queers in the media perpetuates a cycle of hostility and …

Dialogic Praxes In Gabriel Marcel’S Philosophy: Hope For Being In A Technological World, Margaret M. Mullan

Dislocation, distraction, and disconnection present challenges for dialogue and reveal a world broken by technology. A world broken by technology invites a response. Philosopher Gabriel Marcel (1889-1973) offers insightful reflections on ways of being in a broken world. Marcel’s philosophical reflections on body, reflection, intersubjectivity, and technology form the primary content for this dissertation.

In Chapter One, Gabriel Marcel, philosopher, playwright, and international speaker, is introduced as participant in twentieth-century Paris, France. Marcel’s philosophy emerged in response to his societal, technological, and cultural contexts. Chapter …

Reading The Culture Wars In The New Academic Novel, 1984-Present, Ian Butcher

Electronic Theses and Dissertations

The “new academic novel” emerged in the 1980s as what had previously been a cloistered, insular genre began to engage much more directly with the social and political import of universities and the people who work in them. I argue that an important strand of this development centres on a group of novels that through their depiction of recent developments in academia—the threat of political correctness, the so-called theory wars, the growth of contingent labour, and the elevation of a corporate logic above educational concerns—document the emergence of neoliberalism as the dominant logic of American higher education and the American …

Food Protein-Based Core-Shell Nanocarriers For Oral Drug Delivery Applications: (Influence Of Shell Composition On In Vitro And In Vivo Functional Performance Of Zein Nanocarriers, Md Saiful Islam

Electronic Theses and Dissertations

Oral delivery is the most preferred route for drug administration. Oral drug delivery is limited by poor physicochemical properties of drugs and physiological barriers in the gastrointestinal tract. To this end, there is a need for developing new carrier systems to enhance the oral bioavailability of poorly absorbed molecules. Food-grade biopolymers are attractive materials for developing drug delivery carriers’ due to their unique properties and proven safety. Six different core-shell nanocarriers were prepared using food-grade biopolymers including zein-casein (ZC) nanoparticles, zein-lactoferrin (ZLF) nanoparticles, zein-β-lactoglobulin (ZLG) nanoparticles, zein-whey protein isolate (ZWP) nanoparticles, zein-pluronic-lecithin (ZPL) nanoparticles and zein-PEG (ZPEG) micelles.

Politics, Feminism, And Popular Television: Madam Secretary As A Politician, Wife, And Mother, Katie Lynn Schwind

Electronic Theses and Dissertations

A recent surge in political dramas on television has produced an opportunity for media scholars interested in gender, politics, and entertainment media. To date, most research involving the study of fictional politics has revolved around male characters, leaving a gap in the study of female political characters. This study looks at the representation of the character of the US Secretary of State, Elizabeth McCord, in the television drama Madam Secretary in order to evaluate whether the show challenges or reproduces the postfeminist notion that "women can have it all." Through a qualitative textual analysis of six episodes of Madam Secretary …

"Can You Hail Me Now?": Brand, Identity, And Althusserian Ideological Interpellation, Jenna Lo Castro

Electronic Theses and Dissertations

A surge in the role of branding within marketing practices has influenced an

industry transformation. A review of recent literature suggests that brand and the branding process have become integral in sustaining and amplifying organizations. This has been particularly influenced by Integrated Marketing Communication’s (IMC) espousal of being a consumer-driven process. As such, this project seeks to explore the current state of branding practices through the vision of French Marxist philosopher, Louis Althusser. Althusser’s philosophy inspects the human capacity to exercise autonomous decision-making and highlights the influence of social structures upon individuals. Through the Althusserian constructs of ideology and interpellation, …

Getting The Upper Hand: Natural Gesture Interfaces Improve Instructional Efficiency On A Conceptual Computer Lesson, Shannon Bailey

Electronic Theses and Dissertations

As gesture-based interactions with computer interfaces become more technologically feasible for educational and training systems, it is important to consider what interactions are best for the learner. Computer interactions should not interfere with learning nor increase the mental effort of completing the lesson. The purpose of the current set of studies was to determine whether natural gesture-based interactions, or instruction of those gestures, help the learner in a computer lesson by increasing learning and reducing mental effort. First, two studies were conducted to determine what gestures were considered natural by participants. Then, those gestures were implemented in an experiment to …

Hippieland: Bohemian Space And Countercultural Place In San Francisco's Haight-Ashbury Neighborhood, Kevin Mercer

Electronic Theses and Dissertations

This thesis examines the birth of the late 1960s counterculture in San Francisco's Haight-Ashbury neighborhood. Surveying the area through a lens of geographic place and space, this research will look at the historical factors that led to the rise of a counterculture here. To contextualize this development, it is necessary to examine the development of a cosmopolitan neighborhood after World War II that was multicultural and bohemian into something culturally unique. It was within this space that a wellspring of drop-out culture evolved from a combination of psychedelic drugs, experimental lifestyles, and anarchistic thought. The contention of countercultural place was …

Communism's Futures: Intelligentsia Imaginations In The Writings Of The Strugatsky Brothers, Elizabeth Tammaro

Electronic Theses and Dissertations

Arkady and Boris Strugatsky were the most popular science fiction writing duo in Soviet Russia from the 1960s through the 1980s. Examining their imaginative fictional worlds against the background of wider changes in the Soviet Union allows scholars to gain insights in the world of the Soviet intelligentsia, the educated bearers of culture. As members of this group, the Strugatskys expressed the hopes, frustrations and fears, of their peers, vindicating their intellectual and emotional life. I support the argument that the Brothers occupied a middle ground between conformity and dissident, dubbed the "lost" intelligentsia by Lloyd Churchward. I demonstrate this …

Patchwork : A Southern Family Portrait., Rebekah Dement Farmer

Electronic Theses and Dissertations

This dissertation is a jointly scholarly and creative exploration of the potentials of autobiography. Specifically, this dissertation seeks to examine how the personal narrative may be utilized to undermine or challenge prevailing cultural myths and legends of the American South as they are manifested in master narratives propagated within an individual family’s narrative. As emblems of Southern culture, these master narratives have privileged the white male experience over other Southern voices. An interdisciplinary examination of selected historical and literary texts reveals certain external challenges to the resilient master narrative, but this dissertation suggests autobiography may prove a particularly potent force …

To Foster A Culture Of Curiosity: A Hermeneutic Study Of The Experienced Nurse Educator And Student Intellectual Curiosity In The Online Learning Environment, Bedelia H. Russell

Electronic Theses and Dissertations

Skills of inquiry are essential outcomes from a baccalaureate nursing education. Students who demonstrate intellectual curiosity can develop effective skills of inquiry. Nurse educators must place emphasis on teaching and learning strategies which engage student intellectual curiosity. However, the concept of intellectual curiosity is not well-studied across multiple contexts of teaching and learning environments within nursing education. In addition, there is little known about the experienced nurse educator and the meaning of student intellectual curiosity across multiple teaching and learning environments. With the increased emphasis on online teaching and learning in nursing education as a solution for expanding student access …

"This Machine Kills Fascists" : The Public Pedagogy Of The American Folk Singer., Harley Ferris

Electronic Theses and Dissertations

This dissertation examines the figure of the American folk singer as a public pedagogue engaged in rhetorical action for social change. Through four case studies—Woody Guthrie, Bob Dylan, Ani DiFranco, and Tom Morello—the dissertation examines nearly a century of folk music as a form of activism through these four figures. Each folksinger occupies a unique role in a unique era, requiring each musician to revise the work of their musical forebears to accommodate new cultural and technological environments. Drawing on theories of public pedagogy, rhetorical framing, and media, I argue that an effective use of music in social change depends …

The Role Of The Nucleolus In Neurodegeneration., Justin Lauren Hallgren

Electronic Theses and Dissertations

The overarching goal of my studies was to determine the role of the nucleolus in neurodegenerative disease. Numerous studies suggest the impairment of ribosomal biogenesis in neurodegenerative disease and such a condition may contribute to neuronal dysfunction in two ways, loss of function and stress response. Ribosomal biogenesis has been demonstrated to play an essential role in both neuronal growth and maintenance. Therefore insufficient levels of ribosomal biogenesis would be expected to produce atrophy and synapse loss. Moreover, the fidelity of ribosomal biogenesis is monitored by nucleolar and ribosomal stress responses which induce apoptosis and/or cell cycle arrest. Therefore, I …

Reading The Vietnam War And Encountering Other Others: Race And Ethnicity In American Novels Of The Vietnam War, Erin Marie Rentschler

Electronic Theses and Dissertations

This dissertation examines four novels that specifically and deliberately focus on the perspectives of people of color in the United States in order to explore a gap in the conversations surrounding representation of the Vietnam War. Opening the canon to include more diverse perspectives of the Vietnam War acknowledges how predominantly white representation of the war effaces the experiences of the many soldiers of color, who often fought and died in disproportionately greater numbers than white soldiers, and attempts to redress such erasure. These novels include Arthur R. Flowers's De Mojo Blues, which focuses on African American soldiers’ experience and …

Regulation Of Acute And Chronic Immune Responses By Β-Arrestin2, Hui Yan

Electronic Theses and Dissertations

β-arrestin2, previously recognized as a facilitator for G-protein associated 7 TMR desensitization/ internalization, has now been appreciated as an independent signal transducer that regulates multiple cellular responses including inflammation. Cecal ligation and puncture procedure (CLP) induced septic shock is an acute inflammatory response characterized by uncontrolled systemic inflammation. Myocardial ischemia/reperfusion is a chronic sterilize inflammation that requires the reaction of macrophages, fibroblasts and cardiac stem cells for regeneration and remodeling of the infarcted myocardium. Restrained chronic stress is an immune suppression model in which the inactivation of macrophages may be involved. Here we showed β-arrestin2 overexpression inhibited CLP-induced heart dysfunction …

Reel Racism, Real Consequences : A Multiple Case Analysis Of Savior Films As Racial Projects., Eric A. Jordan

Electronic Theses and Dissertations

This thesis analyzes how four blockbuster movies released in the years 2000-2014 represent racial projects. Racial projects encompass anything that helps people understand race. Films are racial projects because of their racist portrayal of characters. Films can be used to train audiences to view race in various ways that may contribute to problematic colorblindness. Specifically, the “White Savior” and “Magical Negro” tropes are ways through which films tell the viewers what to expect from White characters and characters of color. Viewers walk away from these films having constructed a racialized schema about White and Black characters, which further supports the …

Congenic And Functional Analysis Of Rat Mammary Cancer Susceptibility., Saasha Le

Electronic Theses and Dissertations

Breast cancer is a complex disease affected by genetic, epigenetic and environmental factors. The genetic architecture of breast cancer comprises of high to low penetrance alleles. Although low penetrance alleles associate with a small change in an individual’s risk to breast cancer, the total number of variants present and the high population frequency attributes to a much greater population based impact compared to rare high penetrance alleles. Animal models have been used to study these low penetrance modifier alleles in breast cancer. Different rat strains vary in their susceptibility to 7,12- dimethybenzanthracene (DMBA) induced mammary carcinogenesis, with the Wistar- Furth …

“Mere Supplicants At The Gate”: Northeast Tennessee Politics In The Antebellum Era, O.J. Early

Electronic Theses and Dissertations

Antebellum political historians have long studied the era between Andrew Jackson’s election and the secession crisis through the colored knowledge of the Civil War. This project is an effort to reverse that trend. It explores northeast Tennessee’s political culture from the late 1830s through the start of the Civil War. It reveals that the Second American Party System, a wave of new enfranchised voters, and the area’s demographics mixed together to lay a foundation for the aggressive and populist political style that permeated the region from the 1830s through the 1850s. At the heart of these issues was the transition …

A Systematic Review Of Studies Using Gettier-Type Thought Experiments, Maximilian Popiel

Electronic Theses and Dissertations

Experimental epistemologists have recently begun using Gettier-type thought experiments to test various philosophic theories. Generally speaking, these thought experiments present a justified, true belief which intuitively does not seem like knowledge. Despite the studies using this same general definition, they have exercised a myriad of different particular Gettier cases and experimental methods. Some results have been conflicting, or otherwise counter-intuitive, and interpretations of their findings have been divergent. The present study was a systematic review of these experiments, with a focus on experimental methods. Studies were compared on readability and factors effecting participant fatigue and comprehension. The results suggest that …
