From Feminist Activist To Abortion Barbie: A Rhetorical History Of Abortion Discourse From 2013-2016, Skye De Saint Felix

Graduate Theses and Dissertations

This thesis provides a rhetorical history of abortion discourse with an emphasis on the rhetorical moment from 2013-2016. To uncover the rhetorical strategies used to shape consensus on abortion, I highlight three major events—Senator Wendy Davis’s (D-Fort Worth) notorious 13-hour filibuster against Texas’s HB2, the conservative capture of Davis as Abortion Barbie, and the Supreme Court case, Whole Woman’s Health v. Hellerstedt (2016). Because of these key rhetorical moments, pro-choice and anti-choice publics cultivated a period of heightened tension that reinvigorated abortion debates. While pro-choice groups employed narrative to centralize women as rhetorical agents and open spaces to discuss abortion, …

Persistence Of Enteric Viruses On Surfaces Under Varying Environmental Conditions, Nicole L. Turnage

Graduate Theses and Dissertations

Human enteric viruses such as human norovirus (hNoV) and Aichivirus A (AiV) are common foodborne viruses with hNoVs being identified as the leading causative agent of foodborne illnesses in the U.S. Moreover, hNoVs have been identified as the leading cause of nonbacterial acute gastroenteritis in the U.S. and worldwide. Fomite surface contamination is a major transmission route for enteric viruses. The application of an optimized virus recovery method from fomites is essential for better understanding of virus persistence under varying environmental conditions (EC). This study aimed to optimize a surface sampling method for virus recovery from nonporous food contact surfaces …

Characterization Of A Tuberous Sclerosis Complex 2 Variant And Its Interaction Involving The Ras-Related Protein Rheb, Nosaiba Shokr

Graduate Theses and Dissertations

Structure-function relationships of any complex underlie the molecular details of the biological interactions. Rheb, Ras Homology Enriched in Brain, is a Ras-related protein, and it is genetically identified as a molecular switch. Rheb is regulated by cycling between the biologically active GTP and inactive GDP-bound forms. This regulation is partially controlled by an interaction with Tuberous Sclerosis Complex2 (TSC2), a GTPase activating protein (GAP). Upon interaction, TSC2 stimulates Rheb GTP hydrolysis and diminishes the mammalian target of rapamycin (mTOR) pathway. The mTOR pathway is involved in proteins synthesis, cell cycle, and signaling. Mutation in TSC2 causes abnormal activation of Rheb …

The Structural And Functional Properties Of A Double Mutant Of Human Acidic Fibroblast Growth Factor (Hfgf-1), Arwa Mohammed Alghanmi

Graduate Theses and Dissertations

Human acidic Fibroblast Growth Factor 1 (FGF-1), a member of the FGF superfamily, is a potent mitogen and heparin-binding protein involved in a broad spectrum of biological processes, including angiogenesis, cell proliferation, and wound healing. Design of hFGF-1 with an increased thermal stability and an enhanced cell proliferation activity is highly desired for wound healing applications. Herein, we have designed the variant of FGF-1 by substituting two important amino residues in the heparin-binding pocket. The variant was overexpressed in Escherichia coli and was successfully purified to homogeneity using an affinity chromatographic procedure. Far-UV circular dichroism spectroscopic analysis showed that the …

People Change: Impression Management Influences Autobiographical Memories, Holly Elizabeth Cole

Graduate Theses and Dissertations

This paper presents the results of an experiment that tested a new impression management strategy, termed memory enhancement, and the long-term implications of using memory enhancement. People often share the events that occur in their everyday lives to others in the form of stories. This research was designed to determine if people will alter the way they share previous events to create a specific impression. It is possible that using the impression management strategy of memory enhancement will create long lasting changes to the actual memory of the event. This was tested in an experiment in which participants were put …

Products Of Circumstance: Eighteenth-Century Runaway Indentured Servant Advertisements In A Changing Atlantic World, Amanda Page Mcgee

Graduate Theses and Dissertations

Although indentured servitude remained a viable source of labor in colonial America and eighteenth-century England, newspaper advertisements demonstrated the transformations of the perceptions associated with indentured servants in the midst of a changing Atlantic World. Not only were indentured servants perceived as a type of commodity in the rising consumerist culture of the eighteenth century; but, the perceptions of these individuals – reflected in runaway newspaper advertisements – changed depending upon the political, social, and economic circumstances in which they existed. The volatile nature of colonial life combined with the social, economic, and political implications of the changing Atlantic World, …

The Hollow Class: African-American Class-Passing And The Popular, Whitney Martin

Graduate Theses and Dissertations

My project presses to include popular fiction, television, and film for serious critical consideration. To contextualize my research, I use theories that critically examine popular literature, connecting to the work of Janice Radway and Keenan Norris, and I study the African-American focus on class as explored by E. Franklin Frazier. In focusing on the popular, I highlight the everydayness of class and race anxieties. I build on Gwendolyn Foster’s work on class passing but stress racial intersections with identity performance. I rely on New Historicism and Critical Race Theory to substantiate my examination of the literature. I look at specific …

The Functionalization Of N-Cyclobutylanilines Under Photoredox Catalysis, Jiang Wang

Graduate Theses and Dissertations

While transition metal catalyzed cross coupling reactions have become one of the most useful strategies in constructing carbon-carbon and carbon-heteroatom bond formations, major disadvantages such as high reaction temperature, expansive metal catalysts input and limited reaction substrates scope have significantly downshifted the applications of those two electron involved transformations. Comparably, the studies on the redox coupling reactions are less investigated. Derived from single electron transfer process, the redox coupling reactions can be used to construct otherwise challenging chemical bonds efficiently, such as Csp3-Csp3 bond. Recently, visible light mediated photoredox catalysis has merged as a highly prominent tool in the development …

Effects Of Chemical And Enzymatic Modifications On Starch And Naringenin Complexation, Ana Isabel Gonzalez Conde

Graduate Theses and Dissertations

Naringenin is a flavanone naturally present in grapefruit and tomato skin, which has been demonstrated to have health benefits. However, because of the low water solubility and bioavailability, naringenin applications are limited. Starch inclusion complexes have been shown to improve the solubility and bioavailability of poorly water soluble bioactive compounds. The present study aimed to prepare and characterize complexes of naringenin with starches, including potato starch and high amylose corn starch (Hylon VII), which were chemically (acetylation or hydroxypropylation) and enzymatically modified (debranched or debrahced/β-amylase treated). Soluble and insoluble complexes were recovered, and their physicochemical properties were characterized. The treatments …

Virus particles were spiked into the protein feed solutions containing bovine serum albumin (BSA) or lysozyme at different concentrations. Besides protein concentration, the effects of feed pH on the filtration performance and virus rejection were also …

Making Sense Of Nonsense, Parker Boales

Graduate Theses and Dissertations

A paradox of simultaneous sincerity and humor, Making Sense of Nonsense attempts to identify deficient systems upon which we rely daily. Systems of logic, text, and visual language are all rife with flaws solely because their source--humankind--is irrevocably bound to error. This is not to say that these systems cannot be improved; on the contrary, a rigorous investigation of these systems allows one insight into their mechanics to the end that one endlessly questions the very foundation of the mode of communication being used. Materials and discarded objects such as vintage tools, automotive parts, spray paint, string, furniture, plastic, S&M …

To The Moon And Back, Michael Tyler Pennekamp

Graduate Theses and Dissertations

Almost fifty years after the Apollo 11 mission, the moon landing remains one of humankind’s most remarkable technological achievements. On the lunar surface, the Eagle’s flight crew left behind an American flag, mementos honoring those who lost their lives in the quest for such an achievement, and a plaque reading, “Here men from the planet Earth set foot upon the moon. July 1969 A.D. We came in peace for all mankind.” Despite overwhelming proof of this achievement—radio transmissions, photographs, film, rock and soil samples—a sizable minority of Americans continue to view the Apollo 11 moon landing as a hoax. To …

While rock art is only one example of irreplaceable world heritage resources, examining how they decay and what …

Spatial Variability Of Seedling Disease Pressure In Cotton Fields, Kyle Douglas Wilson

Graduate Theses and Dissertations

Seedling diseases are important factors in cotton stand establishment, and seedling disease pathogens are widespread in fields in Arkansas. Little is known about the variability of seedling disease pressure within fields. With expanded adoption of site-specific management and other precision agriculture approaches, cotton producers are increasingly interested in predicting seedling disease pressure, particularly in spatially variable fields. The cotton seedling disease pathogens include the soilborne pathogens Thielaviopsis basicola, Rhizoctonia solani, Pythium spp., and Fusarium spp. These pathogens can survive in soil for long periods and, and when the environment is conducive, these pathogens can act individually or in combination to …

"A Magic Deeper Still": Sacramental Poetics In William Wordsworth, Christina Rossetti, And C.S. Lewis, Eric Michael Bontempo

Graduate Theses and Dissertations

A sacramental poetics requires a particular mode of being-in-the-world. Religiously-minded poets, from Dante and Milton to Donne and Herbert, have long considered how the individual becomes attuned with creation and God’s will. But what happens when modernity and secularization challenge long-held assumptions about the universe and how humankind fits into it? A reevaluation is then needed. My thesis begins with an examination of how William Wordsworth, who sort of falls into modernity, seeks to reoccupy the functions of religion in an increasingly secularized landscape. One consequence of the European Enlightenment is the disentangling and distancing that occurs in regards to …

Assessing Organizational Health Literacy At An Academic Health Center: A Quantitative Research Study, Latrina Y. Prince

Graduate Theses and Dissertations

Inadequate health literacy is a national health problem that affects about 90 million Americans. Health literacy is the degree to which a person is able to make good health decisions based on his/her ability to read, understand, and use health information and services. Organizational Health Literacy (OHL) is the degree to which an organization considers and promotes the health literacy of patients by providing easy to read, understand, and use health information and services. Since it is difficult to determine which patients have inadequate health literacy, a recommended intervention for addressing health literacy is to use OHL practices at all …

Monochamus (Coleoptera: Cerambycidae) are a genus of longhorn beetles commonly known as pine sawyers. They have a worldwide distribution coincident with pines (Pinaceae) and are vectors of the pinewood nematode (Bursaphelenchus xylophilus). In the United States, there are eight known Monochamus species and they have a sympatric distribution with at least one other Monochamus species throughout their range. Monochamus are known to attack stressed, dead, and dying conifers especially pines. In the Ozark- St. Francis National Forest in Arkansas, there are two species of pine sawyers and they share this sympatric distribution observed throughout the United States, M. titillator (southern …

Analyzing The Effects Of Preprimary Broadcast Media On Presidential Nominations From 1980-2016, Jarred Ralston Cuellar

Graduate Theses and Dissertations

This study attempts to discover if broadcast media released during the preprimary period has an effect on the Presidential nomination process, and if so in what way? Several OLS regression models, based on Randall Adkins and Andrew Dowdle’s Presidential nomination forecasting models, were created as an attempt to not only find a statistically significant effect between broadcast media and aggregate vote percentage, but also in an effort to create more effective forecasts. I have drawn my sample from every open nomination race dating back to 1980, and used both cable and network broadcasting sources. I have covered not only the …

Comparison Of Flow Dynamics And Bifurcation Angles In Tributary And Distributary Channel Networks, Thomas Coffey

Graduate Theses and Dissertations

The dynamics of channel mouth bifurcations on river deltas can be understood using theory developed in tributary channel networks. Bifurcations in groundwater-fed tributary networks have been shown to evolve dependent on diffusive ground water flow patterns

directly adjacent to the channel network, producing a critical angle of 72°. We test the hypothesis that bifurcation angles in distributary channel networks are likewise dictated by a diffusive external flow field, in this case the shallow surface water surrounding the subaqueous portion of distributary channels in a deltaic setting. We measured 25 unique distributary bifurcations in an experimental delta and 197 bifurcations in …

An Exploration Of The Experience Of Open Awareness Co-Meditation At The Beginning Of Therapy Sessions, Aneeqa Ishtiaq

Graduate Theses and Dissertations

Mindfulness and meditation have been seen as beneficial for mental health and mindfulness-based therapies have proliferated alongside an increase in popular interest in mindfulness (Germer, Siegel, & Fulton, 2013). However, many therapists are unaware of how to add mindfulness-based interventions. It may seem especially ambiguous for therapists and clients unfamiliar with the concept. In this dissertation, the history and current research on mindfulness-based psychotherapy, and its benefits and contraindications, are reviewed, and the researcher’s relationship to the topic is explained. It is identified that one way to add mindfulness to psychotherapy is for the therapist and the client to co-meditate …

Infrared Energy Conversion In Plasmonic Fields At Two-Dimensional Semiconductors, Gregory Thomas Forcherio

Graduate Theses and Dissertations

Conversion of infrared energy within plasmonic fields at two-dimensional, semiconductive transition metal dichalcogenides (TMD) through plasmonic hot electron transport and nonlinear frequency mixing has important implications in next-generation optoelectronics. Drude-Lorentz theory and approximate discrete dipole (DDA) solutions to Maxwell’s equations guided metal nanoantenna design towards strong infrared localized surface plasmon resonance (LSPR). Excitation and damping dynamics of LSPR in heterostructures of noble metal nanoantennas and molybdenum- or tungsten-disulfide (MoS2; WS2) monolayers were examined by parallel synthesis of (i) DDA electrodynamic simulations and (ii) near-field electron energy loss (EELS) and far-field optical transmission UV-vis spectroscopic measurements. Susceptibility to second-order nonlinear frequency …

Isis In America: A Sociohistorical Analysis, Kathryn Joanne Ratcliff

Graduate Theses and Dissertations

During the summer of 2014, the terrorist organization Islamic State (commonly referred to as Islamic State in Iraq and Syria, or ISIS) garnered international attention after its unprecedented territorial acquisitions and violence in the Middle East. Today, ISIS vies with al-Qaeda for leadership of the global Islamic Extremist movement and has extended its violence all over the world, including the United States. U.S. based supporters generally choose to engage with the ideology in one of three categories: as a foreign fighter, domestic plotter, or domestic non-plotter. Despite this threat, there is very little quantitative research concerning U.S. ISIS supporters and …
