Teaching White Privilege At A Southern University: A Multi-Method Approach, Morgan Browning

Graduate Theses and Dissertations

Fueled by individual and systemic prejudices, racism continuously cycles through American society. Eliminating racism begins with education and awareness on all societal levels. Denying the existence of privilege, specifically White privilege, allows people to ignore racial inequalities and aids in the perpetuation of injustice. This study focused on educating students at a southern university about privilege, oppression, racism, and discrimination with the goal of contributing to a less racist campus. A similar program developed and implemented in a previous study by the researcher was adapted for online modules. These four online modules consisted of presentations, activities, videos, speakers, and reflective …

Media Erasure: A 1904 Lynching In St. Charles, Arkansas, Mary Hennigan

Graduate Theses and Dissertations

As Americans grew increasingly interested in historic racial violence following the Black Lives Matter movement in 2021, select news publications chose to publish apologetic editorials and articles that addressed their failure of inclusive reporting for the last century (Lancaster, 2021; Fannin, 2020). In the theme of acknowledging past mistakes, the Printing Hate project emerged to investigate the power white-owned papers had in influencing lynching incidents in the county (Capital News Service, 2021). The present study examines one Arkansas lynching in 1904 St. Charles. The incident includes the death of 13 Black men. Findings from a content analysis of 70 original …

Breeding Soybean [Glycine Max (L) Merr.] Under Reduced Irrigation, Francia Seconde Ravelombola

Graduate Theses and Dissertations

Soybean [Glycine max (L) Merr.], a legume species native to East Asia in the Fabaceae family, ranks among the most important food crops in the world. It is widely grown and known for its high protein and oil concentration. Soybean is valuable because its seeds have multiple applications in food, feed, pharmaceutical, and industrial enterprises. Even though seed yield is the most important trait, breeders have recently given a significant attention to quality traits, such as high protein or modified oil concentration. Soybean seed protein inheritance has been extensively studied; however, genetics of high-protein ‘BARC-7’ soybean are still unknown.On the …

Post-Obergefell V. Hodges: How Lgbt Contact Can Alter Public Lgbt Policy Positions In The U.S. And Arkansas, Briana Huett

Graduate Theses and Dissertations

The Contact Theory (CT) of attitudinal change has utilized to understand perceptions of minority-group members and the policies that surround them since the 1950s. It has further been used to specifically examine how we form our opinions of LGBT-identifying individuals, the LGBT community, and LGBT policies more generally. However, further evidence is still needed from the CT literature surrounding how this form of contact interacts with individuals’ social identities to determine and alter their LGBT policy positions, how the level of contact with LGBT persons might have differing effects on these positions, and whether LGBT contact holds the same effects …

Social exchange theory and source credibility model were adopted to develop a theoretical framework for the present study. Two Instagram ads were developed that included the post’s image and corresponding caption: VSMI endorsing H&M and …

Growth Differentiation Factor 5 Is A Paracrine Regulator Of Sarcopenic Obesity, Landen W. Saling

Graduate Theses and Dissertations

Sarcopenic obesity attributes to skeletal muscle loss more than sarcopenia and obesity alone. Individuals with SO suffer from the comorbidity of excess body fat and concurrent muscle mass loss due to aging. Growth differentiation factors (Gdfs) have never been recognized as playing a role in skeletal muscle maintenance in those with SO. Specifically, Gdf5, has been recognized as playing a part in Bone Morphogenic Protein signaling to activate protein synthesis and deactivate protein degradation via SMAD 1/5/8 and SMAD 4 complex. Using RNA sequencing, Gdf5 was identified as being significantly upregulated in SO mice. Purpose: To determine the cellular role …

Cyanobacterial And Microcystin Response To Nutrient Additions At Lake Fayetteville Throughout The 2021 Growing Season, Lillie Haddock

Graduate Theses and Dissertations

Harmful Algal Blooms (HABs) are becoming a global concern due to their increasing distribution, frequency, intensity, and the occurrence of toxins. While it is known that eutrophication influences algal blooms, there is less known about what triggers these HABs to produce toxins, especially microcystin. In this study, we conducted 21 community bioassays at Lake Fayetteville, a hypereutrophic reservoir in Fayetteville, Arkansas, from April-November 2021 to examine how the addition of phosphorous and nitrogen influence cyanobacteria concentrations, microcystin concentrations, and microcystin toxin production. These experiments included a control, nitrogen (1.0 mg/L as KNO3), low phosphorus (0.025 mg/L as K2HPO4), high phosphorus …

Evaluation Of The Effect Of A Lippia Organoides Essential Oil Extract On Clostridium Perfringens Proliferation In Vitro And Necrotic Enteritis In Broiler Chickens, Makenly E. Coles

Graduate Theses and Dissertations

The purpose of the present research was to assess the effects of essential oils derived from the plant Lippia organoides on performance parameters, intestinal integrity, and necrotic enteritis (NE) in broiler chickens. To do this, a previously established challenge model for NE was utilized which included challenging with Salmonella Typhimurium on day 0, Eimeria maxima on day 18, and Clostridium perfringens on days 22 and 23. Treatment groups included a 1) non-challenged, negative control, 2) challenged control, and 3) challenged, Lippia origanoides (37ppm in the diet). Group 1 (negative control) had significantly (P < 0.05) higher body weight gain from d8-25 and d0-25 compared to both challenged groups. Feed intake was significantly different for all three groups (P < 0.05) at 8-25 days and 0-25 days with group 1 having the highest feed intake for both time periods. Total mortality was greater in the positive control when compared to both the negative and treatment groups. NE lesion scores were significantly different between all groups with the positive control having the highest mean lesion scores and the negative control having a mean lesion score of 0. The positive control group had the highest FITC-d amounts detected in the sera, being statistically higher than both the treatment group and negative group which were both statistically different from each other. At the present inclusion rate for the essential oil (37 ppm), there was an overall reduction in the negative impact from the NE infection. Further studies should be conducted to reach more significant conclusions.

The Role Of Ccaat Binding Factor In The Regulation Of Catalase Gene Expression In Candida Albicans, Zahra Al-Rumaih

Graduate Theses and Dissertations

Candida albicans is a fungal opportunistic human pathogen. Its infections range from surficial infections like skin rash to fatal systemic infections. Filamentation growth mode is associated with C. albicans virulence because it helps penetration of the host’s epithelial cells. The CCAAT-binding factor (CBF) is a conserved heterooligomeric transcription factor found in 30% of eukaryotes genes. In C. albicans it is composed of 4 major subunits, including Hap2, Hap3, Hap4, and Hap5. Hap2 and Hap5 are essential for DNA binding and function. Hap4 has 3 homologous subunits: Hap41 and Hap42 are putative subunits of CBP. Hap43 is the only Hap4 subunit …

Children’S Social Judgments Of Others On The Basis Of Dialect-Specific Vocabulary, Madison Myers-Burg

Graduate Theses and Dissertations

Many studies suggest that young children prefer speakers who speak similarly to them. Children demonstrate social preferences for speakers of their own native language over speakers of a non-native language as well as for speakers of a familiar accent over speakers of an unfamiliar accent. Recent research suggests that young children will similarly show preference for speakers who use familiar dialect-specific vocabulary over speakers who use vocabulary specific to an unfamiliar dialect. The current study investigated potential motivations behind young children’s preferences for familiar dialect-specific vocabulary. Fifty participants ages fifty-one months to ninety-five months (Mage =72.6 months) viewed an animated …

“Young Adult Books Don’T Realize They Have That Power”: Reader Response To Ideology In Young Adult Dystopian Fiction, Zane Emīlija Sarma

Graduate Theses and Dissertations

The purpose of this research is to find out how readers interact with novels in the Young Adult dystopian genre. I will examine the ways in which readers resist the dominant patriarchal ideological discourses in the YA dystopian novel and how readers submit to this ideology. Through an interaction with the text, the reader produces oppositional, negotiated, or preferred meanings. I will argue that readers’ response to ideology in the YA dystopian novel is affected by their active participation in reader communities such as the Bookish community online.

YA dystopian fiction was highly popular in the early 2010s, but the …

Six Feet Apart: Relational Turbulence Theory And Coping With Covid-19 Within Long-Distance Relationships, Mia Waymack

Graduate Theses and Dissertations

Among research that currently exists, no studies thus far combine elements of COVID-19, long-distance relationships, and Relational Turbulence Theory to explain how each of these elements impacts the others, if at all. Previous research does exist on each of these elements individually, although research regarding the long-term effects of COVID-19 on relationships is minimal considering the pandemic is ongoing. Long-distance relationships have been studied using Relational Turbulence Theory in previous studies within military relationships but have not been studied in connection with either COVID-19 or among college students. This study was conducted by way of qualitative, one-on-one interviews to determine …

Preparation Of Proteins And Peptides From Heat-Stabilized Defatted Rice Bran Via Solid State Fermentation And Investigating For Skin Health, Ali A. Bisly

Graduate Theses and Dissertations

Heat-stabilized defatted rice bran (HDRB) is an abundant and inexpensive agro-industrial by-product of rice milling and rice oil extraction process. Furthermore, HDRB is a potential source of proteins. However, the direct protein extraction has low yield of protein due to the impact of heat stabilization and oil extraction process which made the HDRB proteins bound and interact with other components. This research is based on using solid-state fermentation (SSF), which is a natural and cost-effective approach to facilitate protein extraction from HDRB using Bacillus subtilis (natto) Takahashi as a microorganism.

Response surface methodology (RSM) analysis was used with Box-Behnken design …

Law Enforcement Policy And Personnel Responses To Terrorism: Do Prior Attacks Predict Current Preparedness?, Bryce Kirk

Graduate Theses and Dissertations

Terrorism has been on the mind of the American people and politicians alike since the 9/11 attacks over two decades ago. In the years since, there has been a massive shift in law enforcement priorities from community-oriented policing (COP) to homeland security-oriented policing. This was especially evident in the establishment of the Department of Homeland Security (DHS) shortly after the attacks on the World Trade Center and Pentagon in 2001, which was established to aid law enforcement entities with terrorism preparedness. While prior literature has addressed a variety of factors that have contributed to terrorism preparedness, very little research has …

Voluntary Contacts With Police: Do Differences In Perceptions Of Police Still Exist?, Regan Harper

Graduate Theses and Dissertations

Publicized police misconduct and brutality over the past decade have contributed to increased tensions between the police and community. Exposure to these encounters can result in negative perceptions of police and have serious policy implications for funding of police departments. Although prior research has focused on previous contacts with police, little is known about how voluntary contacts with police can shape an individual’s perceptions. Given the recent death of George Floyd and movement to “defund the police,” the current study aims to determine whether there are demographic differences in perceptions of police among those who have experienced prior voluntary contacts …

A Spatial Analysis Of The Relationship Between Places Of Worship And Criminal Activity In Little Rock, Arkansas, Joseph Charles Williams Iii

Graduate Theses and Dissertations

Research Topic and Gap(s): Previous studies often show negative relationships between religiosity and participation in criminal acts. However, much of the literature revolving around this topic employs a micro-level approach that looks at the religiosity of individuals instead of a macro-level approach that looks at the religiosity of communities. Because this relationship has often been studied from a micro-level perspective, a gap in the literature surrounding macro-level relationships has formed. More specifically, the potential for places of worship to act as buffers against crime has been relatively understudied which furthers the importance of filling this gap in the literature to …

The study includes 10 semi-structured interviews with Bachelor and Master’s level social work students. The findings from this study present necessary characteristics and qualities for effective social work allyship. Interestingly, BIPOC students emphasize the importance of informed action, while White students share relational qualities such as empathy and willingness to learn. The findings also show that some BIPOC students experience performative allyship from White social work students. BIPOC participants …

Algorithms Vs. Human Nature: A Tale Of Selective Exposure, Dené E. M. Wamsley

Graduate Theses and Dissertations

The public’s turn towards news websites and social media for news consumption has sparked anxiety over echo chambers, avoidance of opinion-challenging content, and potentially fragmentation and polarization among sociopolitical groups. Algorithms have specifically been blamed for increasing the ease of filtering out counter-attitudinal online content and potentially exacerbating selective exposure tendencies. However, longstanding classic psychological research has demonstrated the ubiquitous phenomenon of cognitive dissonance and selective exposure far before the internet became the primary tool for news consumption. Research investigating how algorithms directly influence online approach and avoidance behavior is unfortunately scarce. This dissertation work aimed to analyze the impact …

Colloidal Monolayers For Concentration Light In Ultra-Thin Semiconductor Layers, Rachel Cherry

Graduate Theses and Dissertations

Thin film semiconductors are used as photoconductive absorber layers for the development of broadband terahertz generation. Using a femtosecond laser pulse, the generation of a transient increase in the conductivity occurs by photoexciting conduction band electrons in the semiconductor. These thermalize through the emission of terahertz radiation. The route to terahertz generation is not particularly efficient as significant losses come from the absorption in the substrate that is beneath the photoconductive antenna layer. This work explores the application of hexagonally close-packed monolayers of chemically synthesized nanospheres as a potential light concentration method for ultra-thin films of GaAs and black phosphorus …

Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine

Graduate Theses and Dissertations

Macronutrients in the diet are vital to the physiological processes necessary for an organism to effectively clear a pathogen. Diet can be important to a host’s susceptibility to infection and severity of pathology, though results can vary across host-pathogen systems (Sen et al. 2016). Manipulating the ratio of specific macronutrients in the diet is an effective method to begin understanding how individual macronutrients, rather than food types, have on immune responses. Using an avian host-pathogen system, I explored the effects of dietary macronutrient composition, specifically lipid and protein content, on disease pathology and behavior of canaries (Serinus canaria) infected with …

Public Libraries In Rural Arkansas: An Oasis In An Information Desert, Britt Graves

Graduate Theses and Dissertations

Public libraries in Arkansas are welcome, but those found in rural Arkansas are almost a necessity. The public uses the library for more than just checking out books or their email: it’s become a community gathering place for all walks of life, regardless of age or economic status. When the Covid-19 pandemic hit the state, libraries also became essential for education, medicine, news, and employment, nearly overloading their resources and shining a spotlight on technology, or the lack thereof, that so many public libraries are needing. With the Arkansas governor planning an upgrade on broadband technology and the federal government …

Teachers frequently exposed to challenging behaviors experience high levels of stress that transcends into their personal lives. The purpose of this study was to determine how administrators can better support teachers who experience high levels of stress incurred from working with students who exhibit challenging behaviors in the classroom. Data collected through …

On The Same Page: Student Government And The University Administrative Agenda Alignment, James Michael Diloreto-Hill

Graduate Theses and Dissertations

Within institutions of higher education, shared governance is an essential component to a healthy functionality. Among the many stakeholders at these institutions, students are the largest in number and hold primacy. Participation in student governance establishes a sense of shared ownership over their communities while also providing a unique avenue for students to gain wisdom and develop critical skill sets. Senior administrators at these institutions have many inherent challenges due to an organization that is largely decentralized and autonomous (Duderstadt, 2007). Regarding agenda setting, the Garbage Can Model (Cohen et al., 1972) was utilized as a theoretical framework. The purpose …

Investigating The Impacts Of Participating In A Virtual Literacy Clinic: A Case Study Exploring Self-Efficacy In Pre-Service Teachers, Caitlin Mahoney Spears

Graduate Theses and Dissertations

This study describes how participation in a university literacy clinic impacts self-efficacy in pre-service teacher candidates. This study was conducted one and a half years into the global COVID-19 pandemic, creating the need for the clinic’s program, Literacy Camp, to be completed through fully virtual means. Thus, ways in which the pre-service teachers’ experience was impacted by the method of instructional delivery was also detailed. Despite the body of growing research related to virtual learning and efficacy outcomes, there was a gap in the literature related to pre-service teachers’ participation in a fully virtual university literacy clinic and its impacts …

The Hard Work Is Worth It: Overcoming Unfavorable Determinants To Pass Pro-Immigrant Education Policy In A Conservative State Legislature, Megan Cardwell Godfrey

Graduate Theses and Dissertations

Immigrants, English learners (ELs), and culturally and linguistically diverse (CLD)students often lag behind their White, monolingual peers in academic achievement and English language proficiency. While there are policy solutions to improve academic and linguistic opportunities and outcomes for immigrant/EL/CLD students, such as implementing bilingual instructional models and increasing teacher diversity, these pro-immigrant policies can be hard to come by in some legislative contexts due to unfavorable economic, social, or political determinants. This qualitative case study analyzed the multifaceted political work that contributed to the passage of two pro-immigrant education policies in the Arkansas 93rd General Assembly: a bill for bilingual …

Development Of A Long-Read Sequencing Protocol To Assess The Precision And Efficacy Of Gene Editing For Duchenne Muscular Dystrophy, Landon Andrew Burcham

Graduate Theses and Dissertations

This work establishes a method for assessing on-target precision due to CRISPR-Cas9 gene editing, especially within the context of exon skipping therapy for Duchenne Muscular Dystrophy. The proposed method utilizes an Oxford nanopore long-read sequencing approach to sequence amplified regions of DNA that have been edited using CRISPR-Cas9. NIH3T3 and C2C12 cell lines were treated with a dual-guide CRISPR-Cas9 system, that targets and deletes exon 23 from the DMD gene in mouse samples. Deletion PCR revealed deletion of exon 23 in both DNA and cDNA samples. Additionally, sequencing using Oxford Nanopore revealed targeted exon 23 deletion as the most prevalent …
