From An Unlikely Place, Brittany Borcher
From An Unlikely Place, Brittany Borcher
Graduate Theses and Dissertations
From an Unlikely Place, a collection of eight ambitious paintings created while in residence at the University of Arkansas, examines the intersections of landscape painting, gendered gaze, feminine experience and the language of abstraction. One of the challenges I faced while working on this project was finding points of connection between verbal and visual language. As an artist, I consider where vulnerability, sensitivity and generosity intersect my work and am curious about the strange potential an individual's visual language; in my case, a concoction of abstract and figurative forms has to communicate the quality of experience. When placed together on …

Stream Processor Development Using Multi-Threshold Null Convention Logic Asynchronous Design Methodology, Wassim Khalil
Stream Processor Development Using Multi-Threshold Null Convention Logic Asynchronous Design Methodology, Wassim Khalil
Graduate Theses and Dissertations
Decreasing transistor feature size has led to an increase in the number of transistors in integrated circuits (IC), allowing for the implementation of more complex logic. However, such logic also requires more complex clock tree synthesis (CTS) to avoid timing violations as the clock must reach many more gates over larger areas. Thus, timing analysis requires significantly more computing power and designer involvement than in the past. For these reasons, IC designers have been pushed to nix conventional synchronous (SYNC) architecture and explore novel methodologies such as asynchronous, self-timed architecture. This dissertation evaluates the nominal active energy, voltage-scaled active energy, …
The Student-Teacher Romance Film Genre: Hollywood's Historical Representation Of Abuse Of Power, Darby Gilliland
The Student-Teacher Romance Film Genre: Hollywood's Historical Representation Of Abuse Of Power, Darby Gilliland
Graduate Theses and Dissertations
Despite vast literature analyzing films that depict romantic and sexual relationships between young students and their teachers, scholarship has yet to explicitly call this category of films and television a genre. The purpose of the present thesis is to define the student-teacher romance film genre and identify patterns that make it up as a means of illuminating the genre’s exploration of abuse of power in the classroom. I use a historical-generic methodology and gaze theory as a framework to conduct this analysis. I identify three distinct eras of the genre and analyze films from each time period. The first era …

Nutritional Ecology Of The Western Cottonmouth (Agkistrodon Piscivorus Leucostoma), Jason Ortega
Nutritional Ecology Of The Western Cottonmouth (Agkistrodon Piscivorus Leucostoma), Jason Ortega
Graduate Theses and Dissertations
Nutritional ecology aims to understand the factors that shape the diets of animals, how these ingested meals are processed, and how the assimilated nutrients are used to shape an organism’s interactions with its environment. As environmental parameters are altered due to anthropogenic changes, the availability and quality of prey may be altered. The alteration of the nutritional landscape can be devastating to nutritional specialists, yet generalist predators may be able to cope with these changes. The western cottonmouth (Agkistrodon piscivorus leucostoma) is a unique semiaquatic pitviper that can both forage along the land-water interface and in upland habitat when faced …

The Role Of Partisan Politics On Support For Public Institutions Of Higher Education, Jason G. Ramage
The Role Of Partisan Politics On Support For Public Institutions Of Higher Education, Jason G. Ramage
Graduate Theses and Dissertations
Over several decades, a greater share of the expense of earning a college degree has shifted to students and their families as appropriations to public institutions of higher education have declined as a percentage of the overall cost to educate a student. Tuition has greatly outpaced inflation during this period, while inflation-adjusted household income has remained relatively flat. Despite all the benefits that accrue to both the college graduate and society as a whole, for the less affluent, a college education is becoming increasingly difficult to attain. Many decide the financial barriers are simply too great and elect not to …
The Terroir Of Swiss Cheese: A Temporal And Geomorphological Investigation Of The Martian Co2 Sublimation Pits, Racine D. Cleveland
The Terroir Of Swiss Cheese: A Temporal And Geomorphological Investigation Of The Martian Co2 Sublimation Pits, Racine D. Cleveland
Graduate Theses and Dissertations
Observations by NASA Mars Global Surveyor showed evidence of rough topography on the South Pole of Mars. The topography is the result of CO2 sublimation processes that occur through the changing seasons on the red planet. These sublimation areas are known to scientists as Swiss Cheese Features (SCF). SCF are erosional degradation pits that have been studied for over two decades. Studies show that these SCF increase in area over time, but these values are collected by hand on a per feature basis. Models for the pit evolution have also played a part in understanding these SCF. This work is …

Effect Of Human Decellularized Skeletal Muscle On Recovery From Volumetric Muscle Loss Injury, Jacob Schluns
Effect Of Human Decellularized Skeletal Muscle On Recovery From Volumetric Muscle Loss Injury, Jacob Schluns
Graduate Theses and Dissertations
Volumetric muscle loss (VML) overwhelms muscle’s robust capacity for regeneration. A key event in the etiology of VML injury is the bulk loss of structural cues provided by the underlying extracellular matrix (ECM). While muscle is a highly structured tissue, with cell and ECM alignment in the direction of contractile force production, the impact of scaffold alignment on recovery remains unclear. Bulk human decellularized skeletal muscle (DSM) tissues were sectioned into 10 x 1-2 mm fibers. VML defects were repaired using multi-fiber implants consisting of approximately 8 fibers per defect arranged into two layers. Fibers were oriented 1) to the …

The Autistic Perspective: Interviewing Autistic Adults On Lived Experiences With Behavior Modification And How It Has Shaped Their Communication, Lighla R. Whitson
Graduate Theses and Dissertations
The use of behavior modification (BM) based treatment, the best-known example being Applied Behavior Analysis (ABA), is established as an evidence-based practice for promoting communication and other outcomes for Autistic individuals. As such, many Speech Language Pathologists (SLPs) use it in their practice to target various forms of communication. Among many autistic advocacy groups, however, ABA and other BM informed therapies are often described as a detriment to mental and emotional health. Organizations such as the Autistic Self Advocacy Network (ASAN) have come out against the practices and recommend finding different approaches to teaching communication skills. Much research is needed …

Readiness To Lead: Novice School Leaders' Perceptions Of The Impact Arkansas Fellowship Experience On Their Preparedness To Assume School Leadership Roles, Allison Prewitt
Graduate Theses and Dissertations
Research provides increasing evidence that school leadership correlates with school performance (Herman et al., 2016). The leadership skills of K-12 school administrators are linked with student achievement. Evidence indicates that school leaders’ roles continue to evolve as accountability measures change (Grissom et al., 2021). Historically, principal preparation programs emphasized developing management skills. According to research, this is insufficient to prepare instructional leaders for the complex social context of contemporary education (Hernandez et al., 2012; Kerston, 2010; Levine, 2005; Lynch, 2012; Miller, 2013; Zubnzycki, 2013). Unfortunately, most principal preparation programs (PPPs) have not kept pace with the expanding role of principals …
Freedom, Abortion, And Hypocrisy: The Effect Of Hypocrisy On Pro-Life Abortion Attitudes, Emily M. Vance
Freedom, Abortion, And Hypocrisy: The Effect Of Hypocrisy On Pro-Life Abortion Attitudes, Emily M. Vance
Graduate Theses and Dissertations
Previous research suggests that highlighting the gap between inconsistent values can result in long-term attitude change (Rokeach, 1971), that feeling hypocritical might prompt pro-attitudinal behavior (e.g., Dickerson et al., 1992), and that a reactance decoy makes participants more receptive to subsequent persuasive messages (Schumpe et al., 2020). Drawing from these findings, the purpose of the present study was to investigate whether the impact of induced hypocrisy on pro-life abortion attitudes, an attitude commonly grounded in the value of freedom, depended on a reactance decoy. Consistent with Aronson et al.’s paradigm (1991), participants first publicly advocated for the importance of personal …
A Narrative Research Study On How Brazilian Women Executives Build A Sense Of Community And Belonging When Transferred To The United States, Silvia Regina Siqueira
A Narrative Research Study On How Brazilian Women Executives Build A Sense Of Community And Belonging When Transferred To The United States, Silvia Regina Siqueira
Graduate Theses and Dissertations
According to the American Immigration Council (2021), 14 percent of the United States population is foreign-born. Immigrants have enriched American culture and enhanced our influence in the world. People feel a need to belong and have an inherent desire for deep, lasting, and meaningful connections (Baumeister & Leary, 1995). Research suggests that humans are fundamentally and pervasively motivated by a need to belong and the desire to form and maintain enduring interpersonal attachments (Allen, Kern, Rozek, McInerney & George, 2021). These authors also define immigrants’ sense of belonging in terms of how they make sense of their social identification with …

Mitral Valve Imaging And Biomechanics: A Workflow Towards Computational Modeling And Validation, Sam Stephens
Mitral Valve Imaging And Biomechanics: A Workflow Towards Computational Modeling And Validation, Sam Stephens
Graduate Theses and Dissertations
The mitral valve serves a critical role in healthy cardiac function by ensuring the unidirectional flow of oxygenated blood from the left atrium into the left ventricle. It experiences the highest pressures found within the heart and its closure is the result of a complex interaction of several different structures that, furthermore, are unique to each individual. Despite the valve’s vital role however, the specific function of these constituent structures is not fully understood. This, confounded by its asymmetric, personalized nature, make surgical interventions for the mitral valve far less effective than for its neighboring aortic valve. Efforts to overcome …
