The Endurance Of Tell Qarqur: Settlement Resilience In Northwestern Syria During The Late Bronze And Iron Ages (Ca. 1200 – 700 Bc), Eric Robert Jensen

Graduate Theses and Dissertations

This dissertation analyzes the material culture, paleobotanical, and faunal remains excavated at the site of Tell Qarqur, Syria, recovered from occupational levels dating from the end of the Late Bronze Age to the Iron II period (from approximately 1200 to 700 BC). Based on archaeological evidence and ancient textual sources, many ancient Near Eastern kingdoms and polities endured social and political turmoil during the late 13th and early 12th centuries BC. Most likely caused by an unknown hostile group or groups, the destruction of monumental scale architecture and the disruption to the people of Qarqur’s agricultural and animal husbandry practices …

Acculturation And Internalizing Problems Among Latino Youth: A Meta-Analytic Review, Juventino Hernandez Rodriguez

Graduate Theses and Dissertations

Some studies have found acculturation to be a positive predictor of internalizing problems (i.e., anxiety and depression) in Latino youth (Gonzales et al., 2002), whereas other studies have revealed no relation or a negative relation between acculturation and internalizing problems (Smokowski, Buchanan, & Bacallao, 2009). Narrative reviews of this literature exist (Gonzales et al., 2002; Gonzales et al., 2009) but a quantitative synthesis of the literature has not been conducted. After a systematic literature search that identified 38 studies meeting inclusionary criteria, a meta-analysis was performed to estimate the size and direction of the relation between acculturation and internalizing problems. …

Investigating Affective Pathways For The Influence Of Justification On Self-Control, Morgan Hill

Graduate Theses and Dissertations

People struggle with temptation in their everyday lives. Research often attributes failures in self-regulation to overwhelming and uncontrollable impulses. However, research also supports the idea that cognitive factors (e.g., justification) can license tempting behavior and allow individuals to behave in ways that run counter to their long-term goals. In addition, it is likely that affect plays a role in justification-based self-control failure. The current set of three studies investigated the role of affect in justification-based self-control failure. Study 1 tested the prediction that recall of past successes would result in increased positive affect. Study 2 assessed whether justification results in …

A Support Program For College Students With Autism Spectrum Disorder: The Functioning Of Participants Versus Non-Participants And The Role Of Program-Sponsored Mentoring, Ayla Raven Mapes

Graduate Theses and Dissertations

Increasingly more students with autism spectrum disorder (ASD) are attending college. In response, many colleges are now offering these students the extra support of an Autism Support Program (ASP), many of which include a mentoring component. This study is one of only a handful of attempts to examine these programs empirically. Using a small sample of college students who identified as having ASD, I compared participants and non-participants of a university ASP. An online survey was used to assess demographic characteristics and pre-college academic performance, as well as students’ functioning across the following domains: social, adaptive, academic, emotional, and having …

Assessing Rice Consumers’ Preferences And Willingness To Pay In Haiti, Cleeford Pavilus

Graduate Theses and Dissertations

In the last 30 years, rice has become the number one food staple in Haiti, and rice imports have outpaced domestic production to supply the country’s increasing rice demand. Policy makers support the claim that increasing local rice supply will not only reduce the dependency on imported rice but also upheave the national economy. However, there is a lack of information on Haitian consumers’ preferences for rice to aid the development of the local rice supply chain. This research aims to bridge that gap by assessing Haitian consumer preferences and willingness to pay for selected rice quality characteristics. The results …

This dissertation aims to develop a greater understanding of three potentially relevant factors and their respective influences in facilitating college success at the University of Arkansas. First, I evaluate the Student Talent Enrichment Program (STEP) Grant program, designed to fulfill low-income first-year students’ financial needs and encourage their persistence on to their second year of college. Second, I study the effectiveness of the BounceBack …

Counter-Revolution And Egypt’S Lower Middle Class, Keith Glenn Whitmire

Graduate Theses and Dissertations

The Egyptian lower middle class has been declining since the 1970s. Yet since the 2011 uprising and coup d’état the lower middle class has sat in the midst of an economic and political counter-revolution carried out by the police, the military, and Egypt’s intelligence services. In particular, President Abdel Fattah al-Sisi has responded to Egypt’s economic crisis in 2014 and onward by engaging in a program of austerity has sped the decline of the Egyptian lower middle class significantly. The Egyptian lower middle class is in increasing danger of becoming merely educated working poor. Therefore this dissertation will examine the …

Microbiota Metabolic Product Deoxycholic Acid Prevents Campylobacter Jejuni Chicken Colonization Through Modulating Ceca Anaerobes, Bilal Ali Alrubaye

Graduate Theses and Dissertations

Campylobacter jejuni is a prevalent infectious enteritis mainly foodborne from chickens. Despite of reducing C. jejuni food contamination dramatically decreases campylobacteriosis, few effective approaches are available for the bacterial reduction in chickens. The aim of this study was to use microbial metabolic product deoxycholic acid (DCA) to reduce C. jejuni chicken colonization. Broiler chicks were fed 0 or 1.5 g/kg DCA, lithocholic acid (LCA), or urodeoxycholic acid (UDCA) in diets or orally gavaged with cholic acid (CA, 1.5g/kg body weight). Birds were also transplanted with DCA modulated anaerobes (DCA-Anearo) or aerobes (DCA-Aero). Birds were infected with 109 CFU/bird human clinical …

Keeping Pace With Relative Sea Level Rise: Marsh Platform Monitoring Shows Minimal Sediment Deficit Along The Louisiana Coast, Kelly Marie Sanks

Graduate Theses and Dissertations

Recent reports estimate that the marshes of the Mississippi Delta receive just 30% of the sediment necessary to sustain current land area1. An extensive monitoring campaign by the USGS and LCPRA provides direct measurements of sediment accumulation, subsidence rates, and deposit characteristics along the coast over the past 10 years2, allowing us to directly evaluate this sediment balance. By interpolating bulk density, organic fraction, and vertical accretion rates from 273 sites, a direct measurement of organic and inorganic sediment accumulation can be made. Results show that a total of 82 MT/year of sediment is delivered to the coast. Using a …

Irish Whips And German Suplexes: Professional Wrestling And The American Immigrant And Minority Experience, Colin Rush Walker

Graduate Theses and Dissertations

Trends within sports and popular entertainment have long been regarded as great indicators of larger transitions in the social, political, and economic landscape of the United States. Repeatedly mined and often used for context, sports have become intrinsically linked to the broader discussions of people, their beliefs, ideals, and actions occurring in the historiography of American culture. However, one sport has regularly been passed over in these examinations. I argue that the modern day entertainment monolith of professional wrestling serves as one of the most important indicators of socioeconomic change in the history of the U.S., and that it plays …

Three Essays On Corruption And Collusion, Arlo Redwine

Graduate Theses and Dissertations

This dissertation studies corruption and collusion with data derived from a laboratory experiment and household data. In Chapter 1 I study experimental procurement auctions with bribery and a public reserve to test for the tacitly collusive equilibrium described by Compte et al. (2005). Three sellers compete for 40 periods to sell a single item to a computerized buyer who accepts bribes and determines ties in bids and bribes randomly. In the closing periods, only 13.5% of auctions display the collusive equilibrium, but 58.7% of selling prices are noncompetitive. In comparison with simulated predictions for auctions that are corrupt but competitive, …

Philosophia Soteria: How Occupational Safety And Health Professionals Influence Decision Makers, Daniel Jay Snyder

The purpose of this study was to identify ideas about how occupational safety and health (OSH) professionals influence decision-makers on matters impacting occupational health and safety management systems. A modified nominal group technique was used that involved 67 participants in ten nominal groups and identified the most important ideas about how OSH professionals can influence workplace safety and health decision making. The research produced themes of communication, scientific, professionalism, leadership, adaptability, and business acumen that resulted in six domains of occupational safety and health professional influence.

Prison Release, Religious And Civic Contexts, And Recidivism, Samuel Carlson Thomas Iv

Graduate Theses and Dissertations

Under the veil of mass incarceration many of the prisoners will be released, then later readmitted for another crime or parole/probation violations, which falls under the definition of recidivism. Criminologist have attempted to shed light on indicators that explain why some individual prisoners have higher likelihoods than others. I attempt to understand the specific context (at the county level) in which prisoners are released in one point in time and see if the context in which they are released can help explain their likelihoods of recidivating, specifically in the context of religious and civic organizations. I use data from the …

Responsiveness Of Cobb Mv × 700 Broilers To Dietary Amino Acid And Energy Density, Craig William Maynard

Graduate Theses and Dissertations

As new broiler crosses are introduced to the industry, it is of paramount importance to understand their nutritional digressions from previous and other modern broilers. In particular, amino acids (AA) and dietary energy have been identified as key drivers of live performance and carcass composition. In addition, increased nutrient density in broiler diets have been linked to an increase in breast muscle myopathies such as white striping and woody breast. Therefore, a series of trials were conducted to determine the responsiveness of live performance, carcass characteristics, and breast muscle myopathies of Cobb MV × 700 broilers to dietary AA and …

Development Of A Methodology For Predicting Consumer Acceptance And Preference Toward Beverages, Shilpa Shailesh Samant

Graduate Theses and Dissertations

Consumer behavior toward food/beverages is influenced by multisensory attribute perceptions as well as emotional experiences. Traditional methods of sensory testing lack the ability to capture emotional responses and as a result, measuring food/beverage-evoked emotions remains a research challenge. There were three objectives of this dissertation study. Firstly, this study aimed to develop prediction models of acceptance of and preference for basic taste solutions using sensory attribute intensities and emotional responses. Secondly, this study aimed to extend the findings of the first objective to develop prediction models of commercially-available vegetable juice products in terms of (a) acceptance and preference under blind-tasting …

Spatio-Temporal Reconstruction Of Remote Sensing Observations, Kamrul Khan

Graduate Theses and Dissertations

The USDA Forest Service aims to use satellite imagery for monitoring and predicting changes in forest conditions over time within the country. We specifically focus on a 230, 400 hectares region in north-central Wisconsin between 2003 - 2012. The auxiliary data collected from the satellite imagery of this region are relatively dense in space and time and can be used to efficiently predict how the forest condition changed over that decade. However, these records have a significant proportion of missing values due to weather conditions and system failures. To fill in these missing values, we build spaciotemporal models based on …

Periodicals In Transition: Politics And Style In Victorian Higher Journalism, David Blaine Walker

Graduate Theses and Dissertations

Covering a period roughly from the mid-1820s through the early-1880s, this dissertation investigates transformations in the style and substance of political discourse practiced in British organs of “higher journalism.” Animating certain key moments and figures along the way, it explains the shift from a periodical market dominated by the anonymous, lengthy treatises found in quarterly reviews like the Edinburgh Review (f. 1802) and its rivals, to an industry dominated by monthly reviews that generally eschewed both the anonymity of its contributors as well as the prohibitive length of its predecessors. In exploring this transition from the “Age of the Quarterlies” …

Optimizing Methods To Determine Metabolizable Energy Values Of Feed Ingredients For Broilers, Skyler P. West

Graduate Theses and Dissertations

Determination of metabolizable energy (ME) and amino acid (AA) digestibility values of single feed indigents continues to be two of the most important aspects for successful least-cost poultry feed formulation. It would be advantageous if a common diet type could be utilized to determine both ME and AA digestibility values of feed ingredients within a single assay. Two experiments were conducted to evaluate the effect of basal diet type and excreta collection method on the ME value of single feed ingredients determined in broiler chicks using the regression method. In experiment 1, the objective was to investigate the influence of …

Values Vs. Self-Interest As Determinants Of Attitudes: Through A Construal Level Theory Lens, (Sometimes) Self-Interest Wins, Austin D. Eubanks

Graduate Theses and Dissertations

The present study (n = 335) attempted to conceptually replicate Hunt, Kim, Borgida, and Chaiken (2010) with a high-powered design to investigate whether values and self-interest differentially impact attitudes depending on psychological distance. Participants were assigned to complete a task that made self- or other-focused values more accessible, then indicated their attitudes about a student fee increase at a university to fund scholarships the participants would not be eligible to receive (thus going against their own financial self-interest for the well being of someone else). The memo describing the fee increase was manipulated such that the increase would be occurring …

Burning Community Integration And Disability, Christopher Shane Brace

Graduate Theses and Dissertations

Individuals with anxiety and depression have always been marginalized and stigmatized. Individuals with “hidden” disabilities are encouraged by society to keep them hidden, or face ridicule and persecution. Society decreases their sense of self-worth, and self-efficacy by destroying any perception of normalcy. Social support resources are vital for individuals with anxiety and depression’s continued mental health. As time goes on the individuals experience a decrease in the amount of available resources, at the same time the need for them increases. These individuals need a way to quickly replenish their social resources and the Burning Man regional network creates a unique …

Decadal Land Surface Phenology And Water Quality In The Headwaters Illinois River Watershed, Justin Ray Rollans

Graduate Theses and Dissertations

Over 25 percent of the world’s population either lives on or obtains water from karst aquifers. The complex interactions between subsurface karst geologic features, the constant motion of the plant life cycle, and significant water resource demand all suggest the need to better define those interactions. The relationship of historical land surface phenology and water quality in karst topography were investigated in the Headwaters Illinois River watershed in Northwest Arkansas (NWA). This area represents high vulnerability to surface water and groundwater contamination, with both natural and anthropogenic processes such as over application of broil litter for enhanced cattle browse, affecting …

The Impact Of Coaches' Character On Youth Basketball Players, Natasha Hill

Graduate Theses and Dissertations

If utilized effectively, recreation and sports can serve as major tools for developing youth, improving the educational environment, and increasing the number of productive adults that are healthier physically and mentally to positively impact society. Most research targeting recreation and sports developing youth has the perspective primarily of parents and youth. Evaluating the character strengths of coaches and youth athletes who actively participate in team basketball is vital.

An exploration of the value of basketball and character strengths of (n = 64) youth athletes, between the ages of 12 to 16 years, and the impact of their involvement with coaches …

The Role Of Dialect Words In Children’S Social Decisions, Madison Rose Myers-Burg

Graduate Theses and Dissertations

Recent research suggests that young children are capable of distinguishing between phonetically dissimilar spoken accents, yet have difficulty distinguishing between phonetically similar accents (Wagner, Clopper, & Pate, 2013). The present study aimed to determine whether the presence of dialect-specific vocabulary enhances young children’s ability to categorize speakers. Participants completed four training trials in which they were familiarized with photos of two children: one of whom used American English labels for test objects and one of whom used British English labels. After training trials, participants completed eight test trials in which they were asked to infer which target child would use …

This study will examine the relationship among inclusive communication, sense of community belonging, and political participation within local communities. Communication from organizations such as local advocacy and local, mainstream media that contains content acknowledging relevant topics for lesbian, gay, bisexual and transgender (LGBT) community members. I explore ways that Communication Infrastructure Theory (CIT) can be applied to organizational inclusive communication’s influence on community marginalized members’ sense of community belonging and political participation. CIT has been applied to the study of racial and economic minority communities in past research in the past, but this study applies CIT to the study of …

Sustainability Of Utilizing Renewable And Nuclear Energy In Saudi Arabia Using Different Types Of Life Cycle Assessment, Kamel Almutairi

Graduate Theses and Dissertations

Evaluating the global environmental impacts of the current and future energy policies in Saudi Arabia using Life cycle assessment (LCA) method was the main objective of this dissertation. First, the attributional life cycle assessment (ALCA) framework was used to evaluate the Saudi’s air conditioning systems, as they are responsible for about 70% of the total Saudi residential electricity consumption. The ALCA’s results showed that the AC use phase produces the largest share of the environmental impact and the magnitude of the environmental impacts is influenced by the type of primary fuel used for electricity generation.
