"I Like . . . Red Bone:" Colorism, Rappers, And Black College Sorority Women At A Predominantly White Institution, Whitney Frierson

Graduate Theses and Dissertations

In this thesis, I examine black college sorority women’s views about skin tone bias in hip-hop culture. I conduct interviews with 12 black undergraduate women in Black Greek Letter Sororities at a predominantly white institution. Prior research finds that rap music sends skin color messages to adolescent women through lyrical content and music videos. I build on this work by exploring how the experiences of being in college shape black college sorority women’s views on skin tone bias and hip-hop. I find that time in college has been an important life stage in which black sorority women gained an increased …

Impact Of Sanitizers On Salmonella Enterica Contamination And Microbial Populations Of Poultry Processing Reuse Water, Andrew Micciche

Graduate Theses and Dissertations

As human populations increase in numbers, access to clean, fresh water is becoming increasingly difficult to balance between agricultural and municipal demands. Water scarcity is a limiting factor of food production in many countries, whether they are emerging or established economies. In conventional poultry processing systems, access to water is particularly critical for the maintenance and disinfection of processing areas, as well as in processing operations such as scalding, chilling, and carcass washing. The need for sustainable alternatives to single-use water supplies is becoming increasingly more urgent, and as a result, the implementation of water reuse in poultry processing plants …

Rescue And Reestablishment Of Chicken Models For Spontaneously Occurring Hashimoto’S Thyroiditis And Systemic Sclerosis/Scleroderma, Joseph Zolton Hiltz

Graduate Theses and Dissertations

The loss of biodiversity is a topic gaining popularity both in the political and scientific forums. Nearly 30 years ago researchers and politicians congregated in Rio de Janeiro (1992) to attend the first Earth Summit. It was the first meeting of its kind discussing the tangible pressing consequences of biodiversity loss as well as the potential long term ramifications. Many of the countries represented at this summit implemented short and long term plans in order to accurately measure losses of biodiversity as well as establishing organizations to help diagnose and remedy the current problems at hand. These new organizations and …

Tattoo Narratives And Counseling, Danny Lane Mccarty

Graduate Theses and Dissertations

Much research has been done on tattoos and on those who acquire them, but most of the research has focused on negative correlations that might exist with people who have tattoos. This current research, however, showed that people’s tattoo narratives can relate to how they view self, others, and the world, and to how they approach life. A narrative approach to qualitative research was used, and ten people participated in the study. Participants’ views of self, others, and the world were discussed as these views emerged from the narratives. Their possible approaches to life were also addressed. Themes that emerged …

Spirit Don't Ever Die: Apocalypse And Denial In An Infinite Universe, Nathan Riggs

Graduate Theses and Dissertations

In The Great Derangement, Amitav Ghosh catalogs contemporary fiction’s failure to adequately engage with catastrophic climate change. In this thesis, I argue the engagement problem has a century-old analogue in fiction’s approach to entropy. Entropy was among the first secular apocalyptic modes in mainstream discourse, and this investigation of authors’ approaches to its portrayal provides a model for understanding fiction’s denial or acceptance of apocalypse. I first examine William Hope Hodgson’s 1912 novel The Night Land, a far-future tale set in a post-solar Earth. I contend that Hodgson’s centering of the human experience prevents him from portraying a true end …

Communication Infrastructure Theory: A Rural Application, Callie S. Embry

Graduate Theses and Dissertations

The health of a community’s communication infrastructure influences their efficacy and efficiency in dealing with societal problems. The majority of previous communication infrastructure research has focused on multicultural urban centers. This study looks at the communication infrastructure of one rural Arkansas town, specifically looking for the places residents report as communication assets and the subjects discussed within the storytelling network. I used a combination of communication asset mapping and semi-structured interviews to identify the physical locations within the community where residents regularly converse with one another. The interviews along with observations also provided insight into the subject matter that residents …

Influences Of Autism Spectrum Disorder On Sensory And Emotional Responses To Smell And Taste Cues, Asmita Singh

Graduate Theses and Dissertations

Autism spectrum disorder (ASD) is a developmental disability that causes social, communication, behavioral and sensory challenges. The prevalence has been on a rise, with the latest reports stating 1 in 59 children is diagnosed with ASD. These challenges play a significant role in feeding behavior, leading to reduced nutrition among individuals. Much research in this field has been attributed to children, however, this study was focused on the adult population, in an attempt to improve their quality of life. Building on previous findings and knowledge gaps, the objectives of this thesis were two-fold: To better understand the sensory experiences of …

Prediction And Evaluation Of Breast Myopathy, Barbara De Almeida Mallmann

Graduate Theses and Dissertations

Broiler breast myopathies, including woody breast, white striping, and spaghetti breast, negatively impact the industry. Therefore, evaluation, prediction, and frequency of these muscle abnormalities on modern birds are important for decision making. Modern broilers are not highly active and often sit with the breast of the bird resting on the floor. Therefore, the first experiment was to promote bird movement and explore the impact on the breast myopathies. The movement was stimulated by human interaction (walking through pen) and higher light intensity so that birds walked around the pen more often throughout the day. The control group had normal low …

The War On Winter: How Americans Put Down Roots On The Northern Plains, 1854-1949, Daniel J. Fischer

Graduate Theses and Dissertations

My dissertation is a study of how the United States was able to expand onto the Northern Great Plains, consisting of the Dakotas, Nebraska, and the eastern parts of Wyoming and Montana, between 1854 and 1949 despite the threat to property, comfort, and survival posed by the region’s harsh winters, which brought intense cold, large snowdrifts, and blinding blizzards. This dissertation argues that five tools – government programs, rapidly changing technology, imagination, strong local communities, and toughness – allowed native-born Americans and European immigrants to survive and become increasingly secure in the region. But it also argues that severe gaps …

Westward Empire: George Berkeley’S ‘Verses On The Prospect Of Planting Of Arts’ In American Art And Cultural History, Elizabeth Kiszonas

Graduate Theses and Dissertations

This study investigates the extraordinary half-life of a single line of poetry: “Westward the Course of Empire takes its Way…”. Beginning with their composition in 1726 by the Irish- Anglican bishop George Berkeley, these words colonized an enormous swath of cultural landscape over nearly two centuries. Immortalized in newsprint, broadsides, statesmen’s speeches, reading primers, geographies, the first scholarly history of the United States, as well as in poetry, paintings, lithographs, and photographs, the words evolved from an old-world vision of prophetic empire into a nationalist slogan of manifest destiny. Following the poem as it threads through literary and visual culture, …

The Confusing Language Of Mcculloch V. Maryland: Did Marshall Really Know What He Was Doing (Or Meant)?, Sanford Levinson

Arkansas Law Review

All legal “interpretation” involves confrontation with inherently indeterminate language. I have distinguished in my own work between what I call the Constitution of Settlement and the Constitution of Conversation. The former includes those aspects of the Constitution that do indeed seem devoid of interpretive challenge, such as the unfortunate assignment of two senators to each state or the specification of the terms of office of representatives, senators, and presidents. I am quite happy to concede that “two,” “four,” and “six” have determinate meaning, though my concession is not based on a fancy theory of linguistics. It is, rather, a recognition …

Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2017, Leah English, Jennie Popp, Wayne Miller

A Meta-Analysis Of Procedures To Change Implicit Measures, Patrick S. Forscher, Calvin K. Lai, Jordan R. Ast, Charles R. Ebersole, Michelle Herman, Patricia G. Devine, Brian A. Nosek

Psychological Science Faculty Publications and Presentations

Using a novel technique known as network meta-analysis, we synthesized evidence from 492 studies (87,418 participants) to investigate the effectiveness of procedures in changing implicit measures, which we define as response biases on implicit tasks. We also evaluated these procedures’ effects on explicit and behavioral measures. We found that implicit measures can be changed, but effects are often relatively weak (|ds| < .30). Most studies focused on producing short-term changes with brief, single-session manipulations. Procedures that associate sets of concepts, invoke goals or motivations, or tax mental resources changed implicit measures the most, whereas procedures that induced threat, affirmation, or specific moods/emotions changed implicit measures the least. Bias tests suggested that implicit effects could be inflated relative to their true population values. Procedures changed explicit measures less consistently and to a smaller degree than implicit measures and generally produced trivial changes in behavior. Finally, changes in implicit measures did not mediate changes in explicit measures or behavior. Our findings suggest that changes in implicit measures are possible, but those changes do not necessarily translate into changes in explicit measures or behavior.

Education Reform Faculty and Graduate Students Publications

This descriptive, qualitative study, an extension of an experimental primary study, documents stakeholders’ experiences and perceptions of attending multiple field trips where urban elementary students in fourth and fifth grades were randomly assigned to receive three arts field trips including an art museum, a live theater performance, and a symphony concert. Evidence of declining K-12 attendance to educational cultural or arts field trips has been mounting for decades. Further, minority students in struggling schools and their teachers report attending fewer field trip experiences, as well as limited access to arts experiences in their schools. The full impact of this declining …

Analysis Of Rwandan Smallholder Poultry Farmer Needs In Production Manuals, Holly Henry

Poultry Science Undergraduate Honors Theses

As global population continues to grow improving agricultural production become even more important. Smallholder farmers make up a large portion of agricultural production in developing countries (Gueye, 2000; Upton, 2000). East Africa is one sector which has seen growth in poultry production over the pas five years. (Vernooij, Masaki, & Meiher-Willems, 2018). One major constraint to smallholder production is lack of access to educational materials and production guidelines (Mack et al., 2005).

The purpose of the study was to describe methods of production utilized by smallholder farmers in Rwanda and determine what information should be included in a production guide. …

Counterfeit Detection With Multispectral Imaging, Ian Spatz

Electrical Engineering Undergraduate Honors Theses

Multispectral imaging is becoming more practical for a variety of applications due to its ability to provide hyper specific information through a non-destructive analysis. Multispectral imaging cameras can detect light reflectance from different spectral bands of visible and nonvisible wavelengths. Based on the different amount of band reflectance, information can be deduced on the subject. Counterfeit detection applications of multispectral imaging will be decomposed and analyzed in this thesis. Relations between light reflectance and objects’ features will be addressed. The process of the analysis will be broken down to show how this information can be used to provide more insight …

Consumer Perceptions Of Organic, Natural, And Conventional Products When Provided At The Same Price., Kylee Sigmon

Agricultural Education, Communications and Technology Undergraduate Honors Theses

Today’s grocery stores are filled aisle to aisle with an overwhelming variety of options for the consumer. In a consumer-driven market structure, the food industry has grown to encompass many niche markets which meet the ever changing demands of consumers. From organically produced food to more modern agriculture practices and even to finding non-meat protein alternatives, the options are endless. However, in the United States (a country with a higher level of disposable income compared to others), the question arises are customers educated about what the products truly are that they are spending a price premium on?

Optimization Of Ultra-Low Power Application-Specific Asynchronous Deep Learning Integrated Circuit Design, Cole Sherrill

Computer Science and Computer Engineering Undergraduate Honors Theses

The Internet of Things (IoT) consists of all devices connected to the internet, including battery-powered devices like surveillance cameras and smart watches. IoT devices are often idle, making leakage power a crucial design constraint. Currently, there are only a few low-power application-specific processors for deep learning. Recently, the Trustable Logic Circuit Design (TruLogic) laboratory at the UofA designed an asynchronous Convolutional Neural Network (CNN) system. However, the original design suffered from delay-sensitivity issues undermining its reliable operation. The aim of this thesis research is to modify the existing CNN circuit to achieve increased reliability and to optimize the improved design …

The Effect Of Foreign Direct Investment On Food Security: A Case Study From Rural Mozambique, Kali Fleming

Agricultural Economics and Agribusiness Undergraduate Honors Theses

Poverty and food insecurity in the sub-Saharan African region have been exacerbated by the worst drought in 23 years, which impacted 25 countries in Southern and Eastern Africa from 2015-2016. In Mozambique alone it was estimated that the 2015-2016 drought resulted in over 1.5 million people becoming food insecure (FAO, 2016). To mitigate the increasing problem of household food insecurity in sub-Saharan Africa, the World Food Program recommends job creation to target the most vulnerable populations. Job creation is often the result of Foreign Direct Investment (FDI). However, critics of FDI often cite concerns of human rights abuses, inadequate working …

The Effect Of Labeling Information Framing On Genetically Modified Food Choices: A Query Theory Account, Taylor Pruitt

Agricultural Economics and Agribusiness Undergraduate Honors Theses

The progression of policy that regulates genetically modified (GM) food in the US is a prime example of how the role of the government reformulates in relation to societal changes. Support for various labeling programs is formed around key themes which center on the benefits and costs associated with GM labels. The goal of this experiment was to explore the effect of information framing on GM food choices. This was accomplished by presenting information for or against GM labeling in terms of the benefits (positive framing) or costs (negative framing) to consumers. 1,410 consumers participated in an economic experiment where …
