Description Of Job Embeddedness In Arkansas County Extension Agents, Anika Parks

Graduate Theses and Dissertations

The Cooperative Extension System (CES) has had a long-standing problem with the retention of its county Extension agents (CEAs), who are in charge of running various programs in over 3,000 counties within the United States. When a CEA leaves a county, voluntarily or involuntarily, the community members are left without that leader, and their needs go unmet, which was proposed to increase voluntary turnover among CEAs even further. Arkansas CES has had its problems with turnover, and studying this issue through the lens of Job Embeddedness Theory was identified as a gap in the literature.

Job Embeddedness Theory is a …

Investigating The Role Of Social Capital And Everyday Communication In Campus Community Resilience During The Covid-19 Pandemic, Kaleb A. Turner

Graduate Theses and Dissertations

This thesis investigated the role of social capital and everyday communication in campus community resilience capacities during the COVID-19 pandemic. This study conceptualized the university community as a micro-community that experienced sharp disruption as a result of the COVID-19 pandemic. In the same way that traditionally conceptualized communities harness communication to build resilience, this study provides evidence that micro-communities, such as the university campus, have the same potential. Focus groups with students, faculty, and staff, as well as one-on-one semi-structured interviews with students, resulted in 557 pages of single-spaced transcripts that provided rich data to understand this community resilience context. …

Understanding Gender Gaps In Student Achievement And Stem Majors: The Role Of Student Effort, Test Structure, Self-Perceived Ability, And Parental Occupation, Lina Anaya Beltran

Graduate Theses and Dissertations

Increasing women’s participation in Science, Technology, Engineering, and Mathematics (STEM) has become a policy goal for many countries. This dissertation focuses on the origin and measurement of gender gaps in student achievement and self-perceived ability, as well as their potential role in predicting college career choices in STEM.

The first two chapters provide an international overview of gender achievement gaps and focus on issues around measurement using data from the Programme for International Student Assessment (PISA). These chapters study the role of student effort in predicting gender gaps in achievement and whether or not test structure, defined as question difficulty …

Climate Change Frames And Emotional Responses On Reddit, Isabel Iruani Villanueva

Graduate Theses and Dissertations

Climate change remains a highly polarized topic in the United States. Research suggests that the divide in climate change beliefs is partly a result of news media’s representation of select aspects of the problem, or framing. Frames influence individuals’ attitudes, emotions, and behaviors towards climate change. Overwhelming representation of certain climate change frames has led to a lack of emotional connection to the issue, resulting in inaction or dismissal. Climate change researchers have investigated the presence and effects of frames on both news media and select social media sites, particularly Twitter. However, little research has investigated the climate change conversation …

Caring Against The Carceral: How Families Mediate The Social Death Of Incarceration, Jessica Claire

Graduate Theses and Dissertations

Incarceration, especially in the United States, is deeply related to issues of racism, poverty, and citizenship. These particular experiences are the result of a history of biopolitical control affecting Black and brown communities and have a quintessential origin in enslavement. Those who are incarcerated are isolated, dishonored, and powerless as a result of the criminalization of race and poverty. These observations led to questions surrounding the particular impact families may have on the experiences of those who are incarcerated. Families of Incarcerated Loved ones, or FOILs, mediate incarceration through intentional socialization which has the potential to counteract the realities of …

Examining The Demographic And Situational Characteristics That Predict News-Media Coverage Of Bias Homicides:, Caitlin Tidwell

Graduate Theses and Dissertations

Recent trends indicate that incidents of hate crime have become increasingly more violent since 2017, resulting in an overall increase in incidents of bias homicide specifically. Knowledge of bias crime among the general public largely derives from news media sources and, unfortunately, research that illustrates how the media covers and/or portrays bias crime incidents remains underdeveloped. Using theories of strategic news making, the current study examines the types of bias homicide incidents that receive media coverage by constructing a unique database of newspaper articles from prominent, national papers for 216 bias homicides that occurred between 2000 and 2019 drawn from …

Alcohol Abuse And Misuse Amongst Homeless Persons In Northwest Arkansas, Reilly Gibson

Graduate Theses and Dissertations

Alcohol misuse and abuse has been found to be a detrimental risk to individuals having significant impact on their overall health and well-being. Any comprehensive attempt at examining the intersection of alcohol abuse history along with one’s risks and resources as it relates to abuse history among homeless individuals is missing. Using in-depth interviews among homeless adults in Northwest Arkansas (n=168), the current study examines the role of social vulnerabilities, individual risks, and social and psychological resources in explaining alcohol abuse history. Findings support the hypothesis that a person’s vulnerabilities and risks are associated with alcohol abuse histories. Persons who …

Integrating Systems, Processes, And Human Judgment: Three Essays On Value Creation With Supply Chain Analytics, Rebekah Inez Brau

Graduate Theses and Dissertations

Big-data, analytics, automation, and machine learning are changing the role of managers in supply chain and operations functions. Extant research indicates that effective value creation by analytics is achieved through careful attention to three components: technology, people, and processes. As such, the purpose of my dissertation is to improve the integration of people in current supply chain and operations management systems with ever-changing technologies and processes. I focus on one critical function—demand planning—since it is increasingly influenced by predictive analytics yet can still require human judgment. My dissertation is comprised of three essays as follow.

In Essay 1, I implement …

Singing And Pronunciation: A Review Of The Literature, Kassidy Joyner

Graduate Theses and Dissertations

Observed differences exist in the pronunciation abilities of individual language learners, especially adult learners. Musical ability and experience are possible factors that have been attributed to language pronunciation abilities. Although there has been a large amount of research concerning the effects of general musical ability and training on language abilities, very few studies have investigated the musical sub-category of singing. Research on the use of songs in the language classroom has largely tested the effects of song on vocabulary acquisition, while very few studies have explored the effects of song on pronunciation. Given that singing and pronunciation both use similar …

Digital Marketing And The Culture Industry: The Ethics Of Big Data, Jonathan Michael Bowman

Graduate Theses and Dissertations

Instead of the steady march of the one percent growth in ecommerce as compared to total retail revenues in the last decade (to comprise about nine percent of the industry at the close of 2019), we have witnessed leaps now to over twenty percent in just the last year. Scott Galloway marks the pandemic as an accelerant not just of digital marketing posting a year of growth for each month of quarantine but as an accelerant of each major GAFA (Google, Amazon, Facebook, and Apple) firm from market dominance to total dominance (Galloway 2020). Viewing these trends from the standpoint …

Facts From Fiction: Packaging Misinformation, Angel Ray Houts

Graduate Theses and Dissertations

Previous research established that readers learn both accurate and inaccurate information from fictional stories. The current study explored factors that might moderate the impact of misinformation. Participants read fictional stories that contain three assertions; the first two were labeled as set-up assertions, and the last were labeled as the critical assertion. First, there was a manipulation of plausibility of information within the stories by presenting either assertions with truthful information, assertions with small lies (plausible misinformation), or assertions with big lies (implausible misinformation). Second, there was manipulation of reliability of the fictional stories by presenting big lies or truthful information …

The Impact Of Mindfulness On Healthy Food Choices, Kaylea Hopfer

Graduate Theses and Dissertations

The practice of mindfulness has a long history in research, particularly psychological studies. In this paper I examine the effects of a short mindfulness intervention on healthy food purchases. Specifically, I developed an online survey and recruited 634 participants via Prolific between July 24 - July 27, 2020. I randomly assigned participants to either a mindfulness manipulation or a control condition. Following treatment (or control) participants completed a food choice task and various other control. Following the survey, I analyzed data using R version 4.0.2 (2020-06-22) and R-Studio. I estimated three different regression models, ordinary least squares (OLS), Poisson, and …

The Effectiveness Of The Inquiry Based Learning Method In A Private Independent School Environment, Fred R. Eaves

Graduate Theses and Dissertations

The purpose of this study was to examine the effectiveness of an inquiry-based learning model (IBLM) in a small, independent school educational environment. Seisan Academy (SA) implemented a new teaching philosophy that centered around an inquiry-based learning approach with a focus on developing a more student-centered culture at the school. This new program was implemented with little feedback or measurement regarding the effectiveness of the approach. This study also looked to address the lack of formal evaluation regarding the implementation of the IBLM.

A Study Of Student Experiences In The Secondary Transition Program Through Student, Parent, And Teacher Perceptions, Kelley M. Sells

Graduate Theses and Dissertations

The purpose of this research study was to examine and analyze the perceptions of students with mild-moderate disabilities, teachers, and parents regarding the students’ experiences related to their secondary transition plan. More specifically, the qualitative single-case study sought to identify areas of alignment and divergence of these three key members’ perspectives since experiences and perceptions are unique to an individual based on the context and individual’s perspective of the event. These findings suggested that the district showed experiences of valuable student presence and input in their IEP meetings and trusting supportive student-teacher relationships. The study also revealed that significant barriers …

Andragogy For All? A Look At Arkansas Community College Students' Preferences For Andragogical Assumptions, Emilee Sides

Graduate Theses and Dissertations

Community colleges are tasked with juggling multiple missions. They provide open access to education for adults in their community, work with industry partners to educate the local workforce, and provide relevant programming to the communities they serve. When compared with students at four-year institutions, community college students are older, more ethnically and racially diverse, come from lower socioeconomic statuses, and less academically prepared.

Like other community colleges across the country, one of the primary goals of Arkansas community colleges is to help their students succeed. Unfortunately, the state has historically performed poorly in regard to educational outcomes. To get the …

Prediction, Recommendation And Group Analytics Models In The Domain Of Mashup Services And Cyber-Argumentation Platform, Md Mahfuzer Rahman

Graduate Theses and Dissertations

Mashup application development is becoming a widespread software development practice due to its appeal for a shorter application development period. Application developers usually use web APIs from different sources to create a new streamlined service and provide various features to end-users. This kind of practice saves time, ensures reliability, accuracy, and security in the developed applications. Mashup application developers integrate these available APIs into their applications. Still, they have to go through thousands of available web APIs and chose only a few appropriate ones for their application. Recommending relevant web APIs might help application developers in this situation. However, very …

The United States And Portuguese Angola: Space, Race, And The Cold War In Africa, Alex J. Marino

Graduate Theses and Dissertations

This dissertation is an international history of the role of the United States in the process of decolonization in Angola, a former colony of Portugal. I argue that the United States embraced Portugal, Angola, and neighboring Democratic Republic of Congo as irreplaceable Cold War allies. Decolonization in Africa challenged America’s relationship with all three countries, as competing forces within the American public called for Washington to adopt an anti-colonial, anti- racist ideology, while others demanded their government to support white supremacy at home and abroad. Decolonization in Angola, a protracted liberation struggle that started in 1961 and lasted until 1974, …

Self-Deceive And Conquer: A Rhetoric Of Cunning, David Manuel Cajias

Graduate Theses and Dissertations

The purpose of this investigation is to determine the role that self-deception plays in helping demagogues deceive or manipulate their audiences while remaining unaccountable. I will examine the ways in which self-deception aids demagogues and other unethical rhetoricians compellingly present their deceptive belief systems. This is done in a way that their beliefs are only unconsciously known to be false, inaccurate, or incomplete. As this knowledge is subconsciously stored and concealed from the demagogue’s conscience, I will argue that self-deception is the missing piece in the puzzle that is demagoguery.

Demagogic rhetoric has recently experienced a revival due to the …

A Snapshot Semester: Students’ Reflections Of Performance And Mental State Throughout A Graduate Course, Bradley D. Borges

Graduate Theses and Dissertations

Graduate students are anecdotally reputed to be among the most stressed groups of young adults. Common sources of stress for graduate students have included coursework, assistantships, finances, career preparation, and family (Wyatt & Oswalt, 2013; Mazzola, Walker, Shockley & Spector, 2011; Oswalt & Riddock, 2007). Guided reflection can be used by educators to assist students in both learning (Boud, Keogh & Walker, 2013; Kolb, 1984) and managing stress (Shoulders, Whitehead, & Morrison, 2018). By understanding how students’ progress through a semester in terms of both their learning and their management of stress, instructors and academic advisors can better anticipate times …

Insider Trading Enforcement And The Private Information Environment: Evidence From The Newman Ruling, Andrew T. Pierce

Graduate Theses and Dissertations

I exploit a shock to U.S. insider trading law to investigate whether a reduction in the enforceability of tipper-tippee insider trading restrictions leads to changes in information parity among investors and the efficiency of price discovery. The December 2014 Federal Second Circuit Court of Appeals ruling in US v. Newman constrained enforcement by restricting the types of exchanges between managers and investors that trigger tipper-tippee insider trading liability. Following Newman, I find that Second Circuit hedge funds experienced a significant increase in their stock picking ability of Second Circuit stocks in terms of preempting future earnings announcement returns and future …

Dietary Regulation Of Successful Aging, Aubree L. Hawley

Graduate Theses and Dissertations

The current growth of the older population is unprecedented in U.S. history. Chronic disease and functional limitation commonly develop prior to old age, leading to prolonged physical disability and decreased well-being. The development of chronic disease and loss of independence is associated with lean body mass (LBM) loss and fat mass gain beginning in middle age. Therefore, it is important to identify modifiable factors to mitigate deleterious shifts in body composition to promote successful aging (SA). The concept of SA is associated with longevity, the absence of disease and disability, and subjective components of well-being, however, an operational definition has …

Effects Of Alcohol Intoxication On Hostile Attribution Bias And Relational Aggression In Women, Alita M. Mobley

Graduate Theses and Dissertations

Alcohol intoxication is consistently linked to physical and sexual aggression in men, but not women. The lack of evidence supporting the relationship between alcohol and aggression for women could be due to a failure to measure relational aggression (i.e., harmful social manipulation), the form of aggression more commonly employed by women. Further, alcohol intoxication may interfere with the interpretation of social cues, resulting in greater perceived provocation in ambiguous social interactions and increased aggression. The current study examined the relationship between alcohol intoxication and relational aggression in women and the extent to which interpretation of social cues (i.e., hostile attribution …

Evaluating School Counseling Site Supervisors’ Level Of Preparedness To Supervise, Amanda G. Stuckey

Graduate Theses and Dissertations

The purpose of this study was to investigate school counseling site supervisors’ level of preparedness to provide adequate supervision to school counselors in training and determine if any variables could predict the level of preparedness. Professional School Counselors in the United States (N=86) were asked to complete a survey about how prepared they believed themselves to assist a supervisee in developing each ASCA (2019c) School Counselor Professional Standards and Competencies, as well as their training and experience with the supervisory process and supervision models.Results from this study indicate a clear need for continued training, as well as specialized training relevant …

Development Of An Effect Size To Classify The Magnitude Of Dif In Dichotomous And Polytomous Items, James D. Weese

Graduate Theses and Dissertations

A standardized effect size for the SIBTEST/POLYSIBTEST procedure is proposed, allowing for Differential Item Functioning (DIF) to be classified with a single set of DIF heuristics regardless of whether data are dichotomous or polytomous. This proposed standardized effect size accounts for both variability in responses and whether participants are included in the SIBTEST/POLYSIBTEST calculations. First, a new set of unstandardized effect size heuristics are established for dichotomous data that are more aligned with Educational Testing Service (ETS) standards using two and three parameter logistic (2PL and 3PL) models. Second, a standardized effect size is proposed and compared to other DIF …

Legislating Social Inclusion: Social Interaction And Perceptions Of Middle Level Students Toward Those With Disabilities, Deidre Necol Whitehead

Graduate Theses and Dissertations

Recognition of the need for students with disabilities to receive free and appropriate education was brought to the forefront with the passage of Public Law 93 – 112, Rehabilitation Act in 1973. In 1975 Public Law 94-142, the Education for All Handicapped Children Act was enacted requiring all schools to develop and provide a free, appropriate public education for all children and youth with disabilities in the regular classroom to ensure an appropriate education. However, mandating inclusion in classrooms does not ensure social interaction, which is an integral part of learning, especially for early adolescents.

This dissertation uses the Chedoke-McMaster …
