Stay-At-Home Motor Rehabilitation: Optimizing Spatiotemporal Learning On Low-Cost Capacitive Sensor Arrays, Reid Sutherland

Graduate Theses and Dissertations

Repeated, consistent, and precise gesture performance is a key part of recovery for stroke and other motor-impaired patients. Close professional supervision to these exercises is also essential to ensure proper neuromotor repair, which consumes a large amount of medical resources. Gesture recognition systems are emerging as stay-at-home solutions to this problem, but the best solutions are expensive, and the inexpensive solutions are not universal enough to tackle patient-to-patient variability. While many methods have been studied and implemented, the gesture recognition system designer does not have a strategy to effectively predict the right method to fit the needs of a patient. …

The Effect Of Breakfast Macronutrient Composition In Children Ages 7-17 Years Old As A Potential Method To Combat Childhood Obesity, Angela M. Tacinelli

Graduate Theses and Dissertations

The prevalence of childhood overweight and obesity is an ongoing concern. Currently, approximately 20% of children in the United States are obese. While obesity was once regarded merely as excessive adiposity within the body, it is has emerged as a major risk factor for chronic diseases such as metabolic syndrome, type 2 diabetes, and cardiovascular disease. Obesity is multifactorial in nature. Weight gain can result from an energy imbalance in the body due to excess energy intake (calories in) and decreased energy expenditure (calories out). Identifying methods to combat obesity is essential. Nutritional intervention may be a strategy to help …

The purpose of the qualitative research study was to examine how anticipated or experienced stigma associated with chronic pain conditions influenced disclosure of chronic pain for …

An Exploration Of Faculty With Disabilities In Social Work Programs, Kelly Dundon

Graduate Theses and Dissertations

Disability is a unique dimension of diversity, yet structural, social and attitudinal barriers can make meaningful workforce participation difficult for individuals with disabilities. Faculty with disabilities (FWD) are a particularly underrepresented population in academia, and even more so in social work programs. Based on this under-representation and a concern for the lack of attention this population has received, this project will explore a subset of this group. This thesis will focus on faculty with disabilities, first by looking into the scant research pertaining to FWD, then presenting the data from a qualitative study and demographic survey. Implications for policy, practice …

Landscapes Of Danger: A Geospatial Analysis Of Perceived And Realistic Risk In Bryce Canyon National Park, Tia Francis

Graduate Theses and Dissertations

The quantification of risk has inspired a wide breath of literature from the physical sciences, social sciences, and interdisciplinary disciplines like geography. Many attempts to estimate risk via natural hazards either focus on quantifying realistic risk or perceived risk of lay persons, with very little overlap between these paradigms. Due to this, a considerable knowledge gap exists within perceived risk and natural hazards research. This study aims to provide a comprehensive, risk estimation and assessment strategy through a multi-hazard risk assessment of Bryce Canyon National Park (BRCA). This case study analyzed knowledge of risk among visitors with perception surveys and …

Florpyrauxifen-Benzyl Use In Arkansas Rice (Oryza Sativa L.), Hannah Elizabeth Wright

Graduate Theses and Dissertations

Florpyrauxifen-benzyl is a synthetic auxin herbicide which was commercially released in 2018 to combat troublesome grass, broadleaf, and sedge weed species in rice. Many factors may influence cultivar response to a new herbicide; hence, it is important to understand factors contributing to crop sensitivity to an herbicide in order to make appropriate recommendations. Prior to the onset of this study, research had been conducted on florpyrauxifen-benzyl in a flooded environment; however, none had been executed in a non-flooded environment. Experiments were conducted to evaluate the response of a long-grain variety ‘CL111’, a medium-grain variety ‘CL272’, and a long-grain hybrid ‘CLXL745’ …

Use Of Acetolactate Synthase-Inhibiting Herbicides In Inzen Grain Sorghum (Sorghum Bicolor L. Moench Ssp. Bicolor), Hunter Bowman

Graduate Theses and Dissertations

Grain sorghum is typically grown as a rotational crop in Arkansas because of its many benefits, one being the effective control of Palmer amaranth through the use of atrazine. However, limited options exist for postemergence (POST) control of weedy grasses within the crop. Inzen™ grain sorghum is the result of a nicosulfuron resistant weedy sorghum biotype cross-bred with a commercial line of grain sorghum. Inzen™ allows for safe use of over-the-top applications of nicosulfuron within the crop. Nicosulfuron is an acetolactate synthase (ALS)-inhibiting herbicide, which has historically been used in corn for control of weedy grasses. Experiments were conducted in …

Calling Out The Trolls: Responses To Witnessing Use Of The “Troll” Label As A Defense In An Online Group Context, Dene E. M. Wamsley

Graduate Theses and Dissertations

Although the term “troll” has existed since the 1980s, its meaning has shifted in recent years as social media use has increased. People provide contrasting and imprecise definitions for what constitutes “trolling,” and often apply the term subjectively to describe online discussants who are uncivil, who are deviant, and who and present counter-attitudinal opinions. Exposure to deviance, counter-attitudinal information, and incivility often leads to unwanted psychological effects. In theory, labeling an uncivil, counter-attitudinal deviant as a “troll” proposes that their intention is to disrupt the conversation and upset other discussants, which provides a reason for why incivility is used, and …

Under The Radar: The Everyday Resistance Of Anarchist Punks In Bandung, Indonesia, Steve Moog

Graduate Theses and Dissertations

Amidst a current resurgence of hypernationalism across the globe, resistance movements and counterhegemonic ideologies are becoming increasingly visible and more common elements of broader socio-political discourses. While high-profile protests have ignited public interest in resistance movements—turning relatively unknown groups such as Antifa and Black Bloc into household names—little attention has been paid to the behind-the-scenes networks undergirding many of these organizations. Translocal do-it-yourself (DIY) punk rock networks are spaces in which alternative and subversive ideologies are enacted through the everyday implementation of anarchist philosophies and DIY ethics. Here, ‘under the radar’ modes of resistance are found in the lived realities, …

Locating Emergency Shelters While Incorporating Spatial Factors, Justin Taylor

Graduate Theses and Dissertations

In the immediate response phase of a natural disaster, local governments and nonprofit agencies often establish shelters for affected populations. Decisions regarding at which locations to open shelters are made ad hoc based on available building inventory, and may result in high travel impedance to reach shelters and congestion. This thesis presents a shelter location optimization model based on the two-step floating catchment area (2SFCA) method. The 2SFCA method creates a shelter accessibility score for each areal unit (e.g., census block group) which represents the ability for persons in the unit to access shelter capacity with low travel impedance, relative …

Accelerating Leadership And Professional Development For Adults: Developing A New Measure For Assessing Kegan’S Constructive Developmental Orders, Tom Pierce Coker

Graduate Theses and Dissertations

Much has been learned and theorized about adult development and its importance in leadership effectiveness and professional development interventions thanks to the framework proposed by Kegan’s Constructive Developmental Theory (CDT). However, research and practice in this area has been hindered by the difficulty of utilizing the current method for assessing constructive developmental Level, the Subject-Object Interview. The present study addresses this problem through the development and preliminary validation of a new self-report instrument that measures the Levels of development described in Kegan’s CDT. This new measure, the Constructive Developmental Self-Report (CDSR), was constructed through theoretical-based item generation that utilized both …

The first chapter studies the relationship between voluntary beginning teacher turnover and teachers’ levels of conscientiousness. It uses the data from the Beginning Teacher Longitudinal Study and the effort that teachers put on a survey taken during their first year in the profession as a proxy for teachers’ levels of conscientiousness. The results of this chapter indicate that teachers putting …

Markets And Supply Chains: An Investigation Of The Institutions Influencing The Farm-Supply Chain Interface, Jessica L. Darby

Graduate Theses and Dissertations

Farm-level operations have lasting and amplified impacts that promulgate the entire supply chain, and the farm is increasingly in the forefront of today’s headlines on topics such as social responsibility, environmental sustainability, traceability, and food safety. Despite its significance, however, the farm remains a ‘black box’ and has traditionally operated independently with little information-sharing, trust, or collaboration with buyers downstream. This dissertation begins to unpack this ‘black box’ by employing different methodologies to identify the factors influencing exchange in the farm-supply chain interface. In Essay 1, I examine why the farm continues to be a challenge for ‘traditional’ collaborative approaches …

Lay Latitude: Latter-Day Saint Women's Agency In Northwest Arkansas, Andrew Tompkins

Graduate Theses and Dissertations

The question of women’s agency in gender-traditional religions has been the subject of much scholarly attention over the past four decades, but little research has been done focusing specifically on Latter-day Saint women and their identities and roles within the structure and practice of the Church. In popular media representations, Latter-Day Saint women are often depicted as submissive or surviving, either powerless pawns or resistant warriors. However, many Latter-day Saint women find fulfillment and empowerment within and because of, rather than outside or in spite of, the institutional Church. In this thesis, I explore women’s agency in Northwest Arkansas’ Greendale …

The Impact Of The Arkansas Scholarship Lottery On College Choice And Completion Of Adult Students, Collin Callaway

Graduate Theses and Dissertations

In 2008, Arkansas citizens overwhelmingly supported a referendum to legalize a state-run lottery to support college scholarships. The Arkansas General Assembly passed a law in 2009 that detailed administration and procedures of the lottery, and students first received scholarships (branded as the Academic Challenge Scholarship) in fall 2010. The program was largely modeled after other state-run scholarships with two major exceptions: policy makers intentionally established lower eligibility requirements and included adult students. This study measured the impact of the state lottery funded Academic Challenge Scholarship on adult college choice and completion. Findings included significant demographic and college choice differences between …

A Comparative Taxonomic And Diversity Study Of Litter-Associated Fungi In Northwest Arkansas Forests, Rajaa Abdulrazzaq Abbas Al Aanbagi

Graduate Theses and Dissertations

Fungi are taxonomically the most species-rich group of organisms on the earth, ecologically occupy distinctive niches and interact with diverse other organisms throughout their biogeographic distributions and functionally play key roles through their various lifestyles. Plant litter, in particular, is a keystone component in ecosystems and provides heterogeneous microhabitats for the often overlooked litter-decomposing fungi and other organisms on the floor of temperate deciduous forests. Litter fungi involve indirect interactions with the plant, soil and whole food web network. However, the community structure and functions of litter-associated fungi as well as patterns of species richness distributed across various litter microhabitats …

The Dynamics And Effects Of Supply Network Structure, Marat Davletshin

Graduate Theses and Dissertations

The rising interest in network theory among supply chain scholars reflects an emerging shift in perspective. To deliver global speed, efficiency, and responsiveness, modern firms’ supply chains are becoming increasingly complex. The patterns of interactions and interdependencies among hundreds of firms interconnected by these complex supply chains cannot be adequately explored from the dyadic perspective, which has dominated supply chain research for decades. Many supply chain scholars agree that the language of networks can provide a syntax and structure to describe and explore this complex reality. The actual application of network theory in supply chain research, however, has been limited. …

The Stigmatization Of Hunger: The Impact Of Social Stigma On Arkansas Youths’ Food Security, Emily Thompson

Graduate Theses and Dissertations

In Arkansas, 26.3% of children are food insecure, meaning they do not have enough or lack the ability to obtain enough food for adequate nutrition (Miller 2019). In recent years, a new phenomenon has been taking place called lunch shaming where children are sometimes forced to wear signs or handstamps that say the child’s lunch account is overdue. This research analyzes how the media frames food insecurity and how perceived social stigmas affect a student’s willingness to seek out help when struggling with food security.
