Genomic Characterization Of Enterococcus Spp Infecting Chicken Embryo, Aishat Olaoluwa Lawal
Graduate Theses and Dissertations
Chicken embryo mortality has been attributed to bacterial infections and can lead to a decline in hatchability, posing potential losses in the broiler industry. This study aims to investigate the vertical transmission of specific bacterial pathogens from breeder hens to subsequent broiler flocks through MGEs and their association with host specificity. In our sampling of 360 eggs from a broiler flock, we isolated various Enterococcus species, including E. gallinarum and E. faecalis, from incubated egg yolks or aborted embryos. E. avium was found in unincubated bad yolks. Other species like Streptococcus, Lactobacillus, and Bacillus were observed but presumed to be …
Constructing Trust Among Large-Scale Organizations: An Archaeological Case Of Collective Action From Tlaxcallan, Mexico, Marc Daniel Marino
Constructing Trust Among Large-Scale Organizations: An Archaeological Case Of Collective Action From Tlaxcallan, Mexico, Marc Daniel Marino
Graduate Theses and Dissertations
Within nation-states, agencies, cooperatives, and other groups seeking to coordinate in the management of resources, conflicting interests can hinder cooperation and preclude joint action. Increasing transparency in resource management policies and facilitating communication among groups can reduce cooperative dilemmas by building trust. Developments in collective action research have demonstrated that increased communication and transparency among participants can build trust because future outcomes and behaviors can be predicted based on observations of past actions. Archaeology provides case studies to explore some of the earliest attempts by nation-states to reduce tensions caused by competing factions. This dissertation explores one such case study …
Turfgrass Soil Surfactants: Examining Active Ingredients, Application Strategies, And The Structure–Function Relationship In Sand-Based Putting Greens, Daniel O'Brien
Graduate Theses and Dissertations
Soil surfactants, commonly referred to as wetting agents, are a leading water management strategy for golf courses. Non-ionic block copolymers are the most common type of turfgrass soil surfactant. However, differences in the registration process and labeling requirements allow soil surfactants to enter the marketplace accompanied by far-less data compared to other products used on golf courses. This has led to considerable confusion among golf course superintendents. Three primary sources of confusion are: (i) the widely-used marketing terminology of “penetrants” and “retainers” to classify wetting agents; (ii) active ingredients which in some cases are not disclosed at all; and (iii) …
Examining The Relationship Between Mobile Phone Utilization On Self-Directed Online Professional Development Among Early Childhood Practitioners: A Preregistered Study, Jennifer Bowman
Graduate Theses and Dissertations
This study examines Arkansas early childhood practitioners' propensity for self-directed learning when using mobile phones to participate in self-paced online professional development. Further, the activity system model provides context for understanding practitioners' willingness to use technology, like smartphones, to adopt new information when interacting in online learning formats. The problem is that although we must offer professional development to ensure we have competent early childhood practitioners statewide, we are uncertain whether those practitioners have the propensity to use mobile phones to direct their online learning. The purpose of this cross-sectional regression study is to examine the relationship between early childhood …

Graduate Theses and Dissertations
The burgeoning field of 3D food printing introduces opportunities for customizing the physicochemical properties of food, offering tailored solutions in color, shape, and texture. Despite its potential, the implications of this technology on food safety, particularly the efficacy of manufacturer-recommended cleaning protocols for stainless steel food ink capsules, the transferability of pathogens from a contaminated food ink capsule into the food ink based on macronutrient composition of the food, and the impact of storage conditions on pathogen viability, have not been thoroughly investigated. This dissertation provides a comprehensive analysis of these aspects, focusing on the control of foodborne pathogens and …
Salafi Reformist Fatwas And The Challenge To Traditionalism In Egypt And Arabia, 1895 – 1930, Samuel Scurry
Salafi Reformist Fatwas And The Challenge To Traditionalism In Egypt And Arabia, 1895 – 1930, Samuel Scurry
Graduate Theses and Dissertations
Studies of the Islamic intellectual movement commonly known as Salafism have long focused either on the modernist reformers in Egypt and Syria in the late nineteenth and early twentieth centuries, or on the far more austere and sometimes militant iterations of Salafism from the mid-twentieth century to the present day, often associated with Wahhabism. A handful of scholars have examined the links between the two and the transition from the earlier to the later Salafis, however many works which impacted the evolution of Salafism at the dawn of the twentieth century have been neglected, especially those which do not align …
The Gravitational Wave Peep: Improved Modeling Of Highly Eccentric Emris For Lisa Signal Confusion Noise, Daniel Joseph Oliver
The Gravitational Wave Peep: Improved Modeling Of Highly Eccentric Emris For Lisa Signal Confusion Noise, Daniel Joseph Oliver
Graduate Theses and Dissertations
Scattering events around a massive black hole will occasionally toss a stellar-mass compact object into an orbit around the massive black hole, beginning an extreme mass ratio inspiral. The early stages of such a highly eccentric orbit will not produce detectable gravitational waves as the source will only be in a suitable frequency band briefly when it is close to periapsis during each long-period orbit. This burst of emission, firmly in the millihertz band, is the gravitational wave peep. While a single peep is not likely to be detectable, if we consider an ensemble of such subthreshold sources, spread across …
Ripperature: Crossing Gender And Genre, Gracie M. Bain
Ripperature: Crossing Gender And Genre, Gracie M. Bain
Graduate Theses and Dissertations
The murders of Polly Nichols, Annie Chapman, Elizabeth Stride, Catherine Eddowes, and Mary Jane Kelly in London in 1888 by the serial killer commonly known as “Jack the Ripper” were grotesque displays of violence against vulnerable women. As unsolved crimes, they have continuously been sensationalized and fictionalized since they occurred, beginning with dime novels like The Whitechapel Murders; Or, On the Track of a Fiend (1888) and continuing with novels like Stalking Jack the Ripper (2016). The sheer number of adaptations is staggering. This extensive adaptation process results in the mythologization of Jack the Ripper as a culture-text. This study …
Talking About Aphasia: A Social Media Analysis Of What Individuals With Aphasia And Communication Partners Convey About Functional Discourse, Anna Williams
Graduate Theses and Dissertations
This study aimed to blend what we know about aphasia and functional communication. Specifically, how individuals with aphasia are functionalizing communication on the social media platform of YouTube. Extensive clinically significant literature exists on functional communication within speech-language pathology that provides practical guidance for clinical applications. Moreover, an emerging theoretical framework on functional communication and aphasia has sparked fresh insights, particularly from the perspective of individuals with aphasia. This perspective holds promise for exploring how individuals and their families leverage social media for functional communication. This study aims to integrate established clinical research findings on functional communication with the evolving …
Exploring The Governmental Intervention, Journalistic Approach, And Theories Involved In Reducing Poverty Journalistic For A Special Project – Feature Story On Non-Profit Organization Called Circles In Northwest Arkansas, Trevor Spencer
Graduate Theses and Dissertations
Over the 60 years since President Johnson declared the War on Poverty, with close to 40 million people currently in poverty nationwide as of 2022, government measures of the issue, like the Federal Poverty Level and Supplementary Poverty Measure, have continued to be significant determiners for who is constituted as poor. Yet, framing of the poor by sociologists has shifted to a more multi-dimensional approach to who constitutes as poor and how to help them. This means that the definition of poverty is beginning to include a larger set of deprivation unaccounted for in a nation where the definition of …

Examining The Direct And Mediating Relationship Between Immigration, Family Structure, And Crime: A Community-Level Analysis., Obed Asare
Graduate Theses and Dissertations
ABSTRACT Amidst debate about immigration into the United States, many in the public and varying levels of government have questioned its impact on vital social institutions of social control. Public perception often associates immigrants with increased crime, though empirical research reveals a consistently null or negative association at the community-level. Scholars have proposed that immigrants contribute to community revitalization and foster social control, at least some of which may be tied to the ways that immigration reshapes aggregate family structures across the community. However, few empirical studies examine this important relationship. The current study aims to bridge this gap in …
Three Years Of Abrahamic Accords: A Contemporary Episode Of False Peace, Wael Abdelhafez
Three Years Of Abrahamic Accords: A Contemporary Episode Of False Peace, Wael Abdelhafez
Graduate Theses and Dissertations
The Abrahamic Accords mark the latest phase in the peace negotiation efforts concerning the Arab-Israeli conflict. Through diplomatic maneuvers, temptations, and promises, the United States managed to persuade four Arab countries to depart from the principles of the Arab Initiative and instead sign the Abrahamic Accords, establishing full normalization treaties with Israel. Many other countries and significant powers maintain divergent perspectives on the Abrahamic Accords. After three years, The Accords offer numerous potential economic, security, and strategic benefits, with Israel standing to gain the lion's share. This thesis explores the connection between the Frustration-Aggression Theory and the ongoing violence in …
Development Of Genomic Resources And Group Specific Markers For Evaluation Of Genetic Diversity Of Pathogenic Rhizoctonia Species, Juanita Gil Bedoya
Development Of Genomic Resources And Group Specific Markers For Evaluation Of Genetic Diversity Of Pathogenic Rhizoctonia Species, Juanita Gil Bedoya
Graduate Theses and Dissertations
Rhizoctonia is a complex genus in the phylum Basidiomycota comprised of several taxa distributed across different families in the order Cantharellales. Many species in the genus have been identified as plant pathogens, saprobes, or beneficial mycorrhizal symbionts of orchids. Rhizoctonia isolates are divided into binucleate and multinucleate and then classified into anastomosis groups (AGs) based on the ability of compatible hyphae to fuse. Binucleate Rhizoctonia species (Ceratobasidium spp.) are classified into 21 AGs identified with letters (AG-A to AG-U). Multinucleate Rhizoctonia species (Thanatephorus spp.) are identified with numbers and classified into 14 anastomosis groups (AG-1 to AG-13, and bridging group …
Where Will I Be From, Melissa Loney
Where Will I Be From, Melissa Loney
Graduate Theses and Dissertations
Where Will I Be From is an exhibition and film centered around the intersections of generational grief and technology. I documented domestic locations connected to my family across the Great Plains. This on-site photo documentation was then used to create photogrammetric renderings of these locations and their structures, recorded in the open-source CAD software Blender. Together, these familial places, separated by hundreds of miles, were digitally compiled to make one collective world. The aesthetic of this project connects the visual languages of Southern Gothic and Low-Poly Video games. The Gothic nature exposes an isolated decaying presence within a rural landscape. …

Examining The Hormonal Underpinnings Of Affiliation Motivation In Oral Contraceptive Users, Hormonal Iud Users, And Naturally Cycling Women, Mikayla Tolliver
Graduate Theses and Dissertations
Affiliation is important for women during times of stress. Although, affiliation has been linked to women’s hormones across the menstrual cycle, many women use hormonal contraceptives which disrupt the links between hormones, psychology, and behavior. This study examined how hormonal contraceptives (hormonal IUD vs. the oral contraceptive pill) and menstrual cycle phase (follicular vs. luteal) are associated with affiliative motivations following the Trier Social Stress Test (TSST). Further, this study examined women’s cortisol reactivity and whether cortisol reactivity mediated affiliative motivation following the stressor. I found that oral contraceptive pill users projected more stress and rejection onto others’ faces and …
Evaluation Of Oxyfluorfen For Use In Roxy Rice, Casey Hunter Arnold
Evaluation Of Oxyfluorfen For Use In Roxy Rice, Casey Hunter Arnold
Graduate Theses and Dissertations
Mid-southern U.S. rice (Oryza sativa L.) producers are challenged every year to control problematic barnyardgrass [Echinochloa crus-galli (L.) Beauv.] and weedy rice (Oryza sativa L.) because they have evolved resistance to most labeled herbicides. Oxyfluorfen is a Herbicide Resistance Action Committee (HRAC)/Weed Science Society of America (WSSA) Group 14 herbicide that inhibits protoporphyrinogen oxidase within the plant. Currently, there are no HRAC/WSSA Group 14 herbicides labeled for barnyardgrass or weedy rice control in midsouthern rice production. Therefore, oxyfluorfen is being evaluated for barnyardgrass and weedy rice control. Plant breeders at the University of California – Davis were able to breed …

Black African American Men (BAAM) suffer disproportionately from trauma related challenges and have a higher risk of encountering trauma across the lifespan. The negative impact of trauma is a major public health concern in the United States, evidence suggests trauma negatively impacts the physical well-being, mental health, and mortality rate. BAAM have increased rates of trauma exposure and their traumatic experience is historically complex involving a variety of contemporary issues (i.e. Adverse Childhood Experiences (ACEs), depression, victimization and desensitization, stress). This research aims to explore the complex nature of their trauma-related challenges among a purposeful sample of BAAM participants in …
Understanding Multi-Platforming Behavior, Jennifer Large
Understanding Multi-Platforming Behavior, Jennifer Large
Graduate Theses and Dissertations
The focus of this research is to develop a comprehensive understanding of multi-platforming behavior (MPB), which refers to the use of multiple platforms within the same class. While MPB is defined here, the exact nature of this behavior remains a central question addressed in this research. The increasing prevalence of consumers using multiple platforms (ComScore, 2017) necessitates a deeper understanding of usage complexity (Burton-jones et al., 2017) and the value that platforms hold for consumers (McIntyre & Srinivasan, 2017). Consumers evaluate the portfolio of platforms they use when making usage decisions. Examining comparative usage between platforms has implications for both …

Evaluating Garment Fit Perception For Pregnant Women During 1st, 2nd, Or 3rd Trimesters, Nelima Zipporah Barasa
Graduate Theses and Dissertations
During pregnancy, women experience diverse physical body changes as the pregnancy progresses through different periods. It has been noted that anthropometric changes occur during pregnancy in a non-linear manner and can be measured using 3D body scanners at various stages of pregnancy. The changes are diverse, and impact pregnant women's garment fit differently as the pregnancy progresses through each trimester. Pregnant women have experience in dressing their pre-pregnant bodies in stylish garments and would similarly want to dress fashionably when pregnant. This has led to the need for garments that can accommodate body changes comfortably and fashionably without losing the …

Nature achieves molecular self-assembly through the ordered growth of nanoscale building blocks with high efficiency to fabricate macromolecular architectures. One example of self- assembly is peptides folding onto protein is one of the most astounding biological self-assembly processes. When proteins aggregate to form amyloid fibers, the secondary structure of the protein converts from its native state to a cross-beta-sheet. Fibroblast growth factors (FGFs) possess an essential role in neuronal survival during development. In addition, they are involved in neural stem cell (NSC) proliferation. Fibroblast growth factors (FGFs) are well known to be synthesized in the central nervous system (CNS) and …
Adoption And Continued Use Of Irrigation Management Practices In Arkansas, Evelyn Osei
Adoption And Continued Use Of Irrigation Management Practices In Arkansas, Evelyn Osei
Graduate Theses and Dissertations
The paper assesses row crop producers continued use of irrigation management practices, namely the decision to continue rather than stop the use of irrigation practices, using a probit with a sample selection model. To better explain and increase user acceptance, we must understand why producers adopt and continue using irrigation management practices. Past studies have researched the adoption of management practices. However, it is also essential to consider what factors influence continued use and why producers discontinue irrigation practices after adoption. This is the first study to investigate factors influencing the continued use of irrigation management practices in Arkansas. Producers …
A Mixed-Methods Exploration Of Emergency Service Use In Autistic Youth And Young Adults, Rebecca S. Bradley
A Mixed-Methods Exploration Of Emergency Service Use In Autistic Youth And Young Adults, Rebecca S. Bradley
Graduate Theses and Dissertations
Autistic youth are at an increased risk for needing emergency services as compared to neurotypical peers. In fact, approximately 20% of autistic youth will interact with police by the age of 21, and rates of emergency department visits are 30 – 70% higher among autistic individuals than neurotypical peers. While research has begun to explore the nature of emergency service use in this group, researchers have not yet assessed important individual-, family-, and community-level factors that may be associated with these encounters. This study aimed to address this gap in the field by 1) characterizing families of autistic children who …
Understanding The Kinetics Of Laser-Induced Nanowelding Of Nanoparticles And The Motility Of Bacteria When Faced With Obstacles, Ariel Rogers
Graduate Theses and Dissertations
This dissertation has two focus areas: nanoparticle nanowelding and bacteria motility in the presence of micrometer sized structures. There are two main projects for the nanoparticle nanowelding studies: “Real-time imaging of laser-induced nanowelding in solution” and “Two-color laser-induced nanostructure shape modulation.” For the real-time imaging project, I used a fluorescence microscope, a 405 nm laser, and various python packages to quantify the average size of nanowelded nanostructures as a function of time and found that the average nanostructure growth over time fit the parameters of A¯(t) ∝ c0(1−e−t/τ), where c0 represents the initial concentration of nanoparticles in the solution and …
