Male Privilege, Sexual Double Standard, And Sexual Scripts: College Students' Perceptions And Influences Of Hooking Up, Mary Ellen Hunt

Graduate Theses and Dissertations

Approximately three-fourths of young adults in college hook up at least once by their senior year (i.e., engage in a casual sexual encounter outside the context of a committed relationship). There are important gender differences which may inform how men and women conceptualize hooking up. Men and women may have different predictors of interest, expectations of sex, or attitudes toward sex. These gender differences are likely culturally constructed by the sexual double standard and traditional sexual scripts which project men to be the aggressive sexual initiators who want sex all the time, and women to be passive gatekeepers who desire …

Community At The Courts: Social And Community Interactions At Public Basketball Courts, Elizabeth Arnaud Fogle

Graduate Theses and Dissertations

Based on over 60 informal interviews conducted at two public basketball courts, this study utilizes grounded theory to trace class- and race-based differences in the social interactions occurring at both parks. By comparing social interactions between a white, middle class basketball court, and a black, lower class basketball court, I argue that social engagement is not be declining for all segments of society as some theorists suggest. Moreover, I argue that the relationships forged at the basketball court in a predominantly black, working-class neighborhood prove to be more meaningful and have deeper benefits than those forged at a basketball court …

Evaluating The Effects Of The Arkansas Scholarship Lottery On College Participation, Noah Aaron Pittman

Graduate Theses and Dissertations

In recent years, lottery scholarship programs have become a popular policy program for states that wish to help students afford higher education without having to raise new taxes. Through a statewide lottery, profits from the program are passed onto college students in the form of merit-based scholarships. Even with strong opposition from opponents who questioned how much a lottery would benefit the entire population of the state, the Arkansas Scholarship Lottery was created via voter referendum in 2008.

A key goal of the Arkansas Scholarship Lottery was to increase college participation, especially among underrepresented students. The study therefore sought to …

The Effects Of Persuasive Communication On Knowledge And Attitudinal Outcomes Of A Sexual Harassment Training Program, Corinne Marjorie Anton

Graduate Theses and Dissertations

Sexual harassment has been recognized as a prevalent issue leading to multiple negative consequences for victims and perpetrators. Efforts to reduce its occurrence and increase awareness are important. The majority of sexual harassment prevention programs evaluated have used knowledge-enhancing techniques in order to combat sexual harassment; however, results have not yielded a decrease in sexual harassment supportive attitudes. This study examined the effects of a sexual harassment training program that incorporated aspects of the elaboration likelihood model (Petty & Cacioppo, 1986) via manipulation of argument strength and source expertise. A pretest established participants' sexual harassment policy knowledge and attitudes. One …

Essays On Smallholder Farmers In Jamaica: Context-Specific Evidence For Food Security Policymaking, Deborah Evadne Brown

Graduate Theses and Dissertations

This dissertation is comprised of three essays that examined the experiences and welfare of traditional food crop farmers in Western Jamaica. It systematically analyses the interplay between smallholder farmers and often overlooked variables in society. The study used qualitative interviewing, field observations and discourse analysis techniques to generate context-specific evidence for food security policymaking.

The first essay examined smallholder farmers' motives for farming. This formed the basis for a farmer typology that provides a portrait of the participants, and was used to inform findings in subsequent essays in this dissertation. The theory of planned behavior provided the conceptual grounding and …

The Quality Of Presence: An Essential Component Of Therapeutic Work, Melissa R. Haley

Graduate Theses and Dissertations

The concept of therapeutic presence has only recently been addressed in the literature. However the literature regarding this topic indicates that therapeutic presence is an important aspect of effective therapy (Boudette, 2011; Bradford, 2007; Greason & Cashwell, 2009; Hall-Renn, 2006; Nanda, 2009). As much of the literature is comprised of conceptual pieces, empirical data needs to be expanded on regarding therapeutic presence. One of the areas that is not addressed in the literature is how practicing counselors perceive or utilize presence The objective of this qualitative study was to gather information from a sample of expert counseling practitioners concerning therapeutic …

Comparisons Of Hydrogeologic Modeling Methods To Define Capture Zones For Public Water Supply Wells In Northern Arkansas, Paula Anderson

Graduate Theses and Dissertations

The usefulness, applicability, and practicality of more complex and resource consuming methods for groundwater modeling has been in question since computer based groundwater modeling was established (Anderson, 1992). In many situations, computer modeling of groundwater flow is a necessity and useful for extrapolating data where none exists or it is impossible or impractical to acquire. However, when delineating a recharge area around a public water well for protection purposes, it is unknown if more detailed computer modeling results are better than simpler hydrologic calculations and site study. In the case of public drinking water supply wells located in various aquifers …

The Influence Of Literacy On The Lives Of Twentieth Century Southern Female Minority Figures, Laura Leighann Dicks

Graduate Theses and Dissertations

The American South has long been a region associated with myth and fantasy; in popular culture especially, the region is consistently tied to skewed notions of the antebellum South that include images of large plantation homes, women in hoop skirts, and magnolia trees that manifest in television and film representations such as Gone With the Wind (1939). Juxtaposed with these idealized, mythic images is the hillbilly trope, reinforced by radio shows such as Lum and Abner, and films such as Scatterbrain (1940). Out of this idea comes the southern illiteracy stereotype, which suggests that southerners are collectively unconcerned with education …

Assessing The Effectiveness Of Student Oriented Learning Outlines (Solos) In An Equine Classroom, Kathleen S. Jogan

Graduate Theses and Dissertations

This study determined if the use of the student oriented learning outline (SOLO) in a University of Arkansas equine production classroom had a positive influence in three areas: mastery of material taught, retention of material taught and voluntary positive student behaviors related to the use of course material. Thirty-one students who were enrolled in 2012 were in the non-SOLO group (control), and 25 students who were enrolled in 2013 were the SOLO group (treatment). Three separate units were taught to the treatment and control groups with only one difference: the treatment group was given a SOLO one week in advance …

Improving Adjunct Nursing Instructors' Knowledge Of Student Assessment In Clinical Courses, Kelly Vowell Johnson

Graduate Theses and Dissertations

Utilization of adjunct nursing instructors to teach clinical courses is a common occurrence in nursing programs. Adjunct clinical instructors are often expert clinicians, but they have limited experience in teaching and lack the expertise needed to be successful in the educator role, such as knowledge of student assessment. Faculty development programs that focus on student assessment can provide adjunct clinical faculty members with the necessary knowledge to become effective educators and ensure student, faculty, and program success.

The purpose of this study was to examine to what extent a faculty development workshop on evaluating students in clinical courses affected adjunct …

Recruitment, Retention, Job Satisfaction Of Nurse Educators In Arkansas, Peggy B. Lee

Graduate Theses and Dissertations

Facing a crucial shortage of nurses and nurse educators, administrators of colleges and universities need to explore employment and individual characteristics that are related to recruitment and retention of nurse educators. Adding to the nurse and nurse educator shortage is the concern that the population of the United States is aging which creates a growing demand for more RNs. A further issue that complicates the nurse and nurse educator shortage is that nursing education is not producing enough RNs. Schools of nursing are positioned to have to prepare more new nurse graduates over the next decade in an effort to …

A Christian Value?: Faculty Diversity At Southern Evangelical Campuses, Marquita Smith

Graduate Theses and Dissertations

This study explored institutional efforts to increase faculty diversity at three southern Christian universities and provided descriptions of what promoted or curtailed faculty diversity at those institutions. Daryl G. Smith's (2009) dimensions of diversity were used to evaluate the role of institutional missions, and how they were connected to diversity efforts. Smith's 2009 conceptual framework offered four areas for studying diversity: access and success, institutional vitality and viability, education and scholarship, and intergroup relations and campus climate. A qualitative multiple or collective case study design was used. The sample included 20 total participants; 19 from the three case institutions and …

Optimum Design Of Spectral Efficient Green Wireless Communications, Gang Wang

Graduate Theses and Dissertations

This dissertation focuses on the optimum design of spectral efficient green wireless communications. Energy efficiency (EE), which is defined as the inverse of average energy required to successfully deliver one information bit from a source to its destination, and spectral efficiency (SE), which is defined as the average data rate per unit bandwidth, are two fundamental performance metrics of wireless communication systems. We study the optimum designs of a wide range of practical wireless communication systems that can either maximize EE, or SE, or achieve a balanced tradeoff between the two metrics. There are three objectives in this dissertation. First, …

The Effective Use Of The Audit Risk Model At The Account Level, Timothy Andrew Seidel

Graduate Theses and Dissertations

I examine whether auditors effectively respond to an assessment of high control risk at the account level. The audit risk model assumes that auditors alter their audit procedures to compensate for a greater risk of material misstatement to maintain a low risk of audit failure (i.e., low audit risk). I use internal control weakness disclosures in interim and annual filings to identify assessments of high control risk within specific accounts, and restatements of these specific accounts to identify account–level audit failures. I find an increased incidence of account–level misstatements when control risk within that particular account is high, suggesting that, …

A Comparison And Evaluation Of Different Dynamic Characterization Approaches For Bridges, Juan Javier Torres Torres Goitia

Graduate Theses and Dissertations

The objective of this thesis was to compare different dynamic characterization approaches for full scale bridge structures to devise a rapid and reliable Structural Health Monitoring (SHM) program in the aftermath of a natural or manmade hazard. Present methods for structural condition evaluation of bridge structures rely heavily on on-site visual inspections of each structure by specially trained engineers and technicians. It has been proved in the literature that this current method is subjective, time consuming and manpower intensive, all of which are not suited for the critical conditions following a hazard event. This study focused on comparing three different …

Graduate Theses and Dissertations

Experimental modal analysis (EMA) of bridges and other civil structures can be used to acquire quantitative data describing their condition, and enhance opportunities for structural health monitoring and related fields. The use of EMA on civil structures has been limited by the high cost of the excitation devices that are required for the best data quality. The objective of the research reported herein is to evaluate a low-cost excitation system for multiple-input, multiple-output (MIMO) EMA, enabling the production of accurate estimates of the global behavior of in-service bridges.

The prototype excitation system is composed of consumer entertainment devices, namely tactile …

Relationship Between 1,3-Dichloropropene And Nitrogen Fertility In Cotton In The Presence Of Root-Knot And Reniform Nematodes, Amanda Michelle Greer

Graduate Theses and Dissertations

The use of soil fumigation for nematode management in cotton (Gossypium hirsutum) has become increasingly popular in recent years in the absence of effective resistant cultivars. While soil fumigation is relatively expensive, lint yields have consistently been improved to make this practice profitable in fields with severe nematode pressure. Growers in southern Arkansas have observed changes in cotton growth patterns when severely infested fields are fumigated. The most noticeable change has been excessive (rank) growth resulting in an increased need for growth regulators, especially where the nitrogen fertilization exceeds standard recommendations. Field studies were conducted between 2007 and 2010 to …

Health, Nutrition, And Disease In Rural Northern Jordan: A Study Of Enamel Defects Related To Childhood Stress In Skeletal Samples From The Bronze Age To The Byzantine Period, Teresa Veronica Wilson

Graduate Theses and Dissertations

Northern Jordan has seen periods of climate change, political transformation, and economic prosperity between the Late Bronze Age to the end of the Byzantine period. This research tests the assumption that the rural agricultural communities of this region were undernourished by examining the dentition for periodic childhood stress. Canine teeth from five sites (Ya'amun, Sa'ad, Yasileh, Natfieh, and Waqqas) that covered the time periods in question were collected to study overall quality of life.

The teeth were thin-sectioned and examined under a light microscope. Digital micrographs were made of the thin-sectioned teeth in order to record the number and location …

Balking Incidence And Behavioral Responses During Handling In Fed Cattle With Genetic And Carcass Implications, Michelle Lynn Thomas

Graduate Theses and Dissertations

Temperament in cattle is often defined as the reactivity to human handling or novel environments. Temperament differences have been shown among breed-type categories, within breed types, among crossbreds, and between sexes. Temperament tests are typically completed at weaning time on beef cattle, and rarely on fed Holstein steers for beef production. Balking behavior, or cease in forward motion, in the cattle working facility can pose welfare issues as the electric prod use to coerce movement is implemented. Three observational field projects were designed to evaluate balking behavior incidence in unknown breed-types at the processing plant, Holstein steers in the feedlot …

"The Claims Of Religion Upon Medical Men": Protestant Christianity And Medicine In Nineteenth-Century America, Ronald James Gordon

Graduate Theses and Dissertations

This is the first study to examine how pastors lost authority over bodily healing in the nineteenth century. I argue that clergymen adapted to the scientific and cultural developments of the post-Darwin era by encouraging a separation of bodily healing and spiritual healing that was unprecedented in Christianity. In 1840, ministers wielded much more authority than physicians, who still practiced a heroic medicine whose foundations predated Christ. Ministers insisted that doctors' value lay in their willingness to be proselytizing Christians. The doctor who wanted to reach the upper echelon of his profession had to save the souls of the wayward …
