Made Of Water, Covered In Mud, Nicole Norman

Graduate Theses and Dissertations

My fixation on water as metaphor is a product of my cosmic design; Scorpio sun, Pisces moon, Pisces rising. I am made of water, begging to be held. Anything liquid has this same desire. I use my art practice to examine the fluidity of physical and digital spaces; how they transform almost constantly. This is only possible through the use of containers that give form to abstract ideas and make them easier to drink (read: digest). Containers can vary in size and shape, but their purpose remains the same. A drinking glass, a swimming pool, a creek bed. These are …

What's Going On Here, Joanna R. Pike

Graduate Theses and Dissertations

This project is an installation depicting shirts and pants in various degrees of Recognizability. The Components vary from somewhat Unrecognizable to entirely Unrecognizable; Bumps and Blocks are interspersed and interrupt the Semi-logic of What’s going on here while adding repetitive elements to clarify the existence of the Semi-logic. The arrangement of the Components in the installation makes the Unrecognizable forms surrounded by the In-between Space into somewhat Recognizable versions of shirts and pants. The viewer does not fully recognize all the Components, but instead understands the implied Recognition given their existence within the installation. The ideas of Lists, Patterns, Systems, …

The Influence Of Singlet Oxygen And Loss Of Function Of Fatty Acid Desaturase 7 In The Chloroplast On Aphid Resistance In Arabidopsis Thaliana, Hillary Donna Fischer

Graduate Theses and Dissertations

Fatty Acid Desaturase 7 (FAD7) is a chloroplast-localized enzyme that alters the fatty acid content of photosynthetic membranes, and that negatively regulates plant defenses against aphids. Previous studies in the model organism Arabidopsis (Arabidopsis thaliana) have shown that loss-of-function mutations in FAD7 decrease population growth of the green peach aphid (GPA; Myzus persicae Sulzer). This study further characterized the effects of a fad7 null mutant on aphids, and investigated the role of reactive oxygen species (ROS), including singlet oxygen (1O2), in plant responses to aphid resistance in fad7 as well as in wild type plants and a mutant with heightened …

A Tough Nut Never Boils: Thoughts And Ruminations On Language And Playmaking, Lauren Ferebee

Graduate Theses and Dissertations

After an unorthodox journey through higher education ending during the coronavirus pandemic, which has made the typical theatrical thesis production and subsequent typical final year impossible, the author reflects on the body of work she has created at the University of Arkansas as an M.F.A. candidate in playwriting at the Department of Theatre, how she has reached both deeper into her own discipline and outside of it to widen her understanding of liveness, performance, and textual creation. She interrogates her own unexpected experiences, from figuring out how to make theatre without theatres, to teaching students who have never seen a …

Quantifying The Effect Of Intrinsic Aging On Skin Microstructure And Mechanical Function Using Multiphoton Microscopy, Alan Edward Woessner

Graduate Theses and Dissertations

Over the next couple of decades, the number of elderly individuals is expected to double, bringing increased healthcare spending due to seemingly minor injuries to skin. In skin, the 3D dermal collagen fiber network, which is the primary load-bearing structure, undergoes changes in organization and composition due to intrinsic aging. However, the relationships between altered microstructure and mechanical function is not well understood. Quantitative imaging techniques have been used in the past to link skin structure to mechanical function, but previous analysis has been limited to 2D assessments. Multiphoton microscopy (MPM) is a non-destructive imaging technique with intrinsic depth-sectioning capabilities, …

Narrative Inquiry: Life Experiences Of Elite Athletes, Sarah Elizabeth Brown

Graduate Theses and Dissertations

Elite athletes face numerous personal and professional pressures and high-stress experiences; however, there is a gap in the literature connecting identity development with these life experiences. Using narrative inquiry analysis with six emerging adult athletes competing at professional and Olympic levels, this study identified self-narratives they created from life experiences within the context of sport and analyzed when these meanings were formed. Athletes described experiences causing great psychological disturbances as a normal risk within their sport and needing to regulate or compartmentalize their emotions to get through those experiences. Participants discussed various roles they play within their team but lacked …

Crop Response To Low-Dose Dicamba, Mason Castner

Graduate Theses and Dissertations

The introduction of dicamba-resistant (DR) soybean [Glycine max (L.) Merr.] and cotton (Gossypium hirsutum L.) followed by a label allowing over-the-top applications of dicamba in the 2017 provided growers an additional option for broadleaf weed control. Because non-DR soybean is sensitive to low concentrations of dicamba, postemergence dicamba applications present growers choosing to plant non-DR soybean with concerns of damage from off-target movement through physical drift and volatilization of the herbicide as well as tank-contamination from prior dicamba application. Consequences of low-dose dicamba exposure on sensitive vegetative and reproductive soybean have been well researched, but little is known regarding the …

Quantum Dynamical Phenomena In Non-Hermitian And Magnomechanical Systems, Saeid Vashahri Ghamsari

Graduate Theses and Dissertations

In this dissertation, we have investigated quantum dynamics via three case studies. First, we studied a system of two coupled waveguides respectively carrying optical damping and optical gain in addition to squeezing elements in one or both waveguides. Such a system is expected to generate highly entangled light fields in the two waveguides. We, however, show that the degree of the created entanglement is significantly affected by the quantum noises associated with the amplification and dissipation. Because of the noise effect, one can only have nonzero entanglement for a limited time interval. Second, we generalized the first project by considering …

Optimization Of Broken Rice Consumption Through Understanding The Confluence Of Sensory And Economic Preferences, Matthew Greer Richardson

Graduate Theses and Dissertations

The authors were perplexed by the seeming dichotomy between the majority 70% of Haitian consumers being chronically food insecure, but still preferring to pay premium international market prices for long-grain rice that constitutes 30% of the calories in this poorest nation in the Western Hemisphere. The aim of this study was to determine the optimal percent broken rice in regards to price specifically to Haiti. Optimization between quality and price point is seen as the best rice for the price, and can be found through combining individual preferences with willingness to pay. Broken rice (brokens) garner a significantly discounted price …

Memory And Rememory: Critically Cultivating An Appropriate Response Through A Storied Approach To Listening, Katie W. Powell

Graduate Theses and Dissertations

This dissertation argues for a storied approach to listening from the perspective of a white Southern woman. To do this, I carefully followed the work of two community groups. One, the Washington County Community Remembrance Project, is working to install a marker venerating Aaron, Anthony, and Randall, three enslaved people who were lynched in our area in 1856. The other, the James H. Berry United Daughters of the Confederacy, is responsible for installing a Confederate statue on the Bentonville Square in 1908 that was removed in 2020. As illustrated by the use of archival research and embedded participation in interracial …

Consumer Motivations And Perceived Value In Online Second-Hand Luxury Fashion Shopping, Murphy Brianne Aycock

Graduate Theses and Dissertations

The second-hand luxury fashion market is growing four times faster than the primary luxury fashion market and already represents a $24 billion market today (Beauloye, 2019; Siwak, 2020). Younger generations such as millennials and Gen Z are buying and selling preowned luxury products almost three times faster than any other age group (Beauloye, 2019). Digital selling platforms such as The RealReal and Vestiaire Collective are fueling the growth of the second-hand luxury fashion market (Beauloye, 2019). Despite the increased consumer interests and sales growth in the second-hand luxury fashion market, existing research has not concentrated on the underlying motivations of …

Rewriting Web 2.0 Discourses Of The Local For Socio-Spatial Literacy Theory, Erin Daugherty

Graduate Theses and Dissertations

This dissertation seeks to provide a framework for engaging with two spatial concepts that have been foundational to theorizing literacy across time but have often been taken for granted as passive backdrops to the social action of literacy practice: the notions of “the local” and “the global.” By interrogating the histories, both past and ongoing, of these two spatial concepts as they are interwoven into the sociocultural paradigm of literacy theory, research, and pedagogy, this project identifies new ways that literacy researchers and educators can attend to spatial concepts so as to promote and encourage literacy research and learning that …

Extreme Far-Right Murder-Suicide Attacks In The U.S. And Germany: A Comparative Storyline Analysis, Hayden Lucas

Graduate Theses and Dissertations

Despite increasing empirical research on suicide terrorism since the 9/11 terrorist attacks, prior studies have focused primarily on radical Islamic terrorism in non-Western contexts. As a result, less is known about how murder-suicide attacks committed by other ideological movements unfold, particularly the extreme far-right in North America and Europe. Researchers have begun to theorize the social and psychological processes believed to play a role in the radicalization of suicide terrorists. However, the observable, situational processes shaping radicalized individuals when planning, preparing for, and executing suicide terrorism remain underexplored. Therefore, the purpose of this study is to identify intervention points by …

Graduate Theses and Dissertations

The objective of this case study was to analyze the spatial distribution patterns of the residences of registered sex offenders in Pulaski County, Arkansas to determine the impact of state enforced residence restrictions. Density and clustering factors were used to identify census tracts of the study area with high and low concentrations of offenders. These zones were then compared to identify which characteristics were similar and dissimilar between high and low concentration zones. The results indicate that there is a non-random distribution of registered sex offenders in the study area. The findings also indicate that the residence restrictions placed on …

Immersive Systems And User Engagement Through Neurois Lens, Ali Balapour

Graduate Theses and Dissertations

Immersive systems (e.g., Virtual Reality) are at the forefront of the next generation of innovative technologies. Recent technological advancements have made them viable for businesses and individuals to adopt. For example, some realtors now offer virtual house tours in the absence of walk-ins. The concept of “immersion” is at the heart of these technologies. However, despite the fact that this concept has been studied for almost three decades, our understanding remains weak and inconsistent. Specifically, there remains a lack of consensus on what it is, its antecedents, and how it should be measured.

This dissertation includes two essays. In Essay …

I Matter: Understanding The Self-Care Practices Of School Counselors During The Covid-19 Pandemic And How Internal And External Factors Create Barriers, Alisha Rene Marie Jones

Graduate Theses and Dissertations

Diminished self-care practices and heightened stress of school counselors is a continuing problem in education. With role ambiguity, high student-to-counselor ratios, emotional exhaustion, and others adding pressure to the roles and responsibilities of school counselors, this study investigated the self-care practices of Missouri school counselors and the internal and external factors which influence them, specifically within the context COVID-19. Clayton Alderfer’s (1972) Existence, Relatedness, and Growth theory was used as a theoretical framework for chosen self-care practices represented in this study and was supported by Robert Kegan’s and Lisa Lahey’s (2009) Immunity to Change theory to understand the competing commitments …

Social Acceleration In The Marketplace: Three Essays Exploring The Intersection Of Culture And Consumption, Sarah Grace

Graduate Theses and Dissertations

Consumer culture is fast. Goods, services, people, ideas, and values – the material and nonmaterial aspects of culture – are moving more quickly throughout the marketing system than ever before. Such acceleration effects diverse stakeholders: people, public, and planet. This dissertation explores the phenomenon of ‘social acceleration’, and specifically, the ‘acceleration of the pace of life’ which examines the feeling that time is going faster in modern societies as a result of “the increase of action episodes per unit of time” (Rosa 2013, 80). This project develops an understanding of how meanings in marketing are socially constructed in relation to …

Values And Success In Collegiate Athletics, Nathan Shelby Hutchens

Graduate Theses and Dissertations

The rapid commercialization of intercollegiate sports has changed the landscape of the hiring decisions and methodologies within university-associated athletic departments – especially within the Division I Football Bowl Subdivision (DI-FBS) (Wong, 2017). Most notably and recently, the strategies used to hire athletic directors (ADs) have underwent considerable revision – yet successful hires are far from a sure thing. Many strategies include allusions to leadership style, yet leadership styles are as numerous as there are researchers who study them – and are rarely implemented holistically, thus making their assessment and associated outcomes tenuous at best (Peachey et al., 2015). Hambrick and …

Investigative Study Of Microalgal And Electrochemical Wastewater Treatment Systems And Modeling Of The Wafer-Enhanced Electrodeionization Using Supervised Learning, Humeyra Betul Ulusoy Erol

Graduate Theses and Dissertations

Wastewater has a serious impact on environment and public health due to its high concentration of nutrients and toxic contaminants. Without proper treatment, excess nutrients discharged in wastewater can cause a damage to the ecosystem such as undesirable pH shifts, cyanotoxin production, and low dissolved oxygen concentrations.

Main objectives of this dissertation work were to investigate i) the biofuel potential of P. cruentum when grown in swine wastewater, ii) the influence of four most commonly used ion exchange resins on the system efficiency and selectivity for the removal of sodium, calcium, and magnesium ions, and iii) the modeling of wafer-enhanced …

The Double Edge: Contradictory Functions Of Civil Society Organizations In The Tunisian Democratic Process, Dhia Ben Ali

Graduate Theses and Dissertations

“Democratic transition,” the act of becoming democratic, and “democratic consolidation,” the subsequent actions that solidify the achievement of becoming democratic, are two separate processes that go hand in hand. While several Arab Spring nations overthrew their dictators, fewer underwent a democratic transition, and only one – Tunisia – achieved democratic consolidation (Bouchlaghem and Thepaut, 2019; Sadiki, 2019; Gianni, 2019). Tunisia constitutes the sole Arab Spring country to have: 1) created and adopted a new constitution; 2) formed and institutionalized political parties that peacefully share power; and 3) achieved multiple rounds of free and fair elections (Al-Anani, 2014; Yerkes, 2019). Scholarly …

This research explores how news media influences negative attitudes towards criminal justice reform and Black identity. Utilizing Framing Theory, this study focuses on whether negative stereotypes in crime news triggers racial prejudice and bias towards African Americans. Participants of this study will consist of current students at the University of Arkansas, Fayetteville. The findings suggest that knowing the race of a potential criminal assailant influences respondents’ attitudes towards presumptions of guilt, future criminality, and criminal …

Racial Terror Lynching In Northwest Arkansas: Recounting Of The Story Of Three Enslaved Males Lynched In 1856 In Washington County - Documentary, Obed Lamy

Graduate Theses and Dissertations

While Northwest Arkansas is considered as diverse and progressive today, it also shares a common history of racial violence, and yet almost unknown, with the Southern United-States. Little is being said about the slave plantations in Elkins, racial cleansing in Springdale, or public spectacle lynchings in Fayetteville. This is because white people who hold political and economic power also control how history is written and decide what is to be learned from their perspectives. Marginalized communities, especially Black people, have not always had agency to tell their own stories. The lynchings of three enslaved males, Anthony, Aaron, and Randall, in …

New Normal: How School Operation And Learning Changes In A Pandemic, Margaretha Audrey Stefani Cahya

The current COVID-19 pandemic, which lasted for more than a year during the study, has brought notable educational changes at every level of education. This research was conducted to explore the extent of educational changes during a pandemic and the deviation between the education plan and its implementation in Northwest Arkansas public school districts. The study's data was collected from school district public documents and teacher interviews from school districts classified as low to high SES in suburban and rural areas. Both sources were analyzed and …

Description Of Job Embeddedness In Arkansas County Extension Agents, Anika Parks

Graduate Theses and Dissertations

The Cooperative Extension System (CES) has had a long-standing problem with the retention of its county Extension agents (CEAs), who are in charge of running various programs in over 3,000 counties within the United States. When a CEA leaves a county, voluntarily or involuntarily, the community members are left without that leader, and their needs go unmet, which was proposed to increase voluntary turnover among CEAs even further. Arkansas CES has had its problems with turnover, and studying this issue through the lens of Job Embeddedness Theory was identified as a gap in the literature.

Job Embeddedness Theory is a …

Pathogenicity Of Staphylococcus Agnetis Associated With Lame Broilers With Osteomyelitis, Sura Faris Salih Zaki

Graduate Theses and Dissertations

We developed High Resolution Melt Analysis (HERMA) as a rapid and reliable molecular diagnostic assay for the detection and identification of the main bacterial species recovered from the blood and lesions of bacterial chondronecrosis with osteomyelitis (BCO) from the lame broilers at the University of Arkansas poultry research farm. Also, the present study confirms that raising young birds on suspended wire flooring has been proved to successfully induce lameness attributable to BCO with birds being more susceptible to bacteraemia than those that were raised on litter flooring. The newly described pathogen, Staphylococcus agnetis, has been reported to be overrepresented in …

Methods And Effects Of Shadowing Using Online Authentic Videos On L2 Acquisition Of Mandarin Chinese Tones, Ai-Ling Lu

Graduate Theses and Dissertations

Mandarin Chinese tones are notoriously difficult for second language (L2) learners. Previous research focuses on tone training methods that can help learners produce monosyllabic lexical tones, and studies about the production of multisyllabic lexical tones at the sentence level in spontaneous speech are limited. This study applies shadowing—a method where the learners repeat what they heard with as little delay as possible—to tone training and compares the effects of using authentic videos and textbook audios as shadowing materials for beginner L2 Mandarin learners’ tone improvement at the sentence level. Fourteen students in elementary Chinese classes at an American university participated …

Investigating The Role Of Social Capital And Everyday Communication In Campus Community Resilience During The Covid-19 Pandemic, Kaleb A. Turner

Graduate Theses and Dissertations

This thesis investigated the role of social capital and everyday communication in campus community resilience capacities during the COVID-19 pandemic. This study conceptualized the university community as a micro-community that experienced sharp disruption as a result of the COVID-19 pandemic. In the same way that traditionally conceptualized communities harness communication to build resilience, this study provides evidence that micro-communities, such as the university campus, have the same potential. Focus groups with students, faculty, and staff, as well as one-on-one semi-structured interviews with students, resulted in 557 pages of single-spaced transcripts that provided rich data to understand this community resilience context. …
