Private And Federated Deep Learning: System, Theory, And Applications For Social Good, Han Hu

Dissertations

During the past decade, drug abuse continues to accelerate towards becoming the most severe public health problem in the United States. The ability to detect drug­abuse risk behavior at a population scale, such as among the population of Twitter users, can help to monitor the trend of drug­abuse incidents. However, traditional methods do not effectively detect drug­abuse risk behavior in tweets, mainly due to the sparsity of such tweets and the noisy nature of tweets. In the first part of this dissertation work, the task of classifying tweets as containing drug­abuse risk behavior or not, is studied. Millions of public …

Improving Programming Learners’ Experience Through Interactive Computer Tutor Based Moocs, Ruiqi Shen

Dissertations

With the large demand for technology workers all around the world, more people are learning programming. Studies show that human tutoring is the most effective way to learn for novice programmers. However, problems such as the inaccessibility to physical classes, prohibitive costs, and the lack of educators may limit students' opportunities to learn from these resources. Additionally, because programming is a skill requiring continuous practice and immediate feedback, simply listening to lectures may not be sufficient to learn effectively. This increases the inconvenience of learners who use online learning tools such as Massive Open Online Courses (MOOCs).

Employees' Expectations Of Leadership Development Programs And Their Effects On Anticipated Voluntary Employee Turnover And Organizational Commitment, Candace Johnson

Dissertations

Employee retention and commitment have gained attention over the past years (Mutsuddi, 2016). Commitment is the link that connects an individual to their organization, thereby decreases the probability of turnover (Allen & Meyer, 1990; Hague et al., 2019). According to Mutsuddi (2016), decreasing employee turnover remains a critical element for sustainment in any organization. However, most organizations invest in policies and practices to increase employee commitment; those same practices can lead to employee turnover (Mutsuddi, 2016). This study explores the effects of leadership development programs and their impact on organizational commitment and anticipated voluntary employee turnover. A qualitative research design …

Walking Into A News Desert: How Arkansas College Newspapers Are Coping With The Decline In Print Journalism, David Keith

Dissertations

News deserts is a reference to geographic areas — most commonly counties — where no newspaper is published. The number of these areas continues to grow as more newspapers shut their doors because of financial difficulties brought on by a lack of advertising, a lack of readers, and the shift to online news consumption. College students studying journalism find themselves on the cusp of entering a profession where the number of workplaces and jobs is shrinking. They know it and the advisers of their college newspapers know it. Even with this arid prospect before them, the students are reporting news …

An Exploration Of Black Church Leaders' Intentions To Develop Critical Consciousness Among African-American Students, Taheesha Quarells

Dissertations

African-American students experience human capital opportunity and achievement gaps. Researchers have called for culturally relevant strategies to help close the gaps. The historic Black Church, a part of many African-American students’ culture and community, is a historic and current source of social capital for positive human capital development outcomes. Critical consciousness develops positive human capital outcomes, such as academic achievement, in African-American and other minority students. Much of the literature on critical consciousness is quantitative in nature and therefore does not include the intentions or the willingness of organizations to develop critical consciousness. Therefore, there is a need to understand …

Personal And Organizational Characteristics Impacting Employee Self-Efficacy, Justin Chandler

Dissertations

COVID-19 forced organizational shutdowns across the globe in 2020, sending unemployment levels in the United States to nearly 15%, with approximately 20.5 million Americans unemployed by May 2020 (Falk et al., 2021; Kochhar, 2020). Virtual business meetings became the norm, while some employees experienced job loss and salary cuts (Prochazka et al., 2020). Many employees worldwide became unsatisfied with their work situation and less confident of their capabilities (Ragheb et al., 2020) and have experienced career shock due to the pandemic.

Coombs’s Strategic Crisis Communication Theory to examine the public relations strategies and effectiveness of Mississippi’s three largest public universities, the University of Mississippi, Mississippi State University, and the University of Southern Mississippi, related to the historic decision to retire the state of Mississippi’s flag in 2020. Facing significant reputational threat and public pressure from students and faculty, the universities became public advocates for a new state flag in 2015 and 2016, when each chose to refrain from flying the flag—a flag that featured the Confederate battle emblem for more than 100 years—on its campuses. The universities …

How Immigrant English Language Learners Used Internal Fortitude To Utilize Supports And Overcome Obstacles To Graduate From High School, Mark C. Peterson

Dissertations

Immigrants and English Language Learners (ELL) continue to receive attention in the research literature due in part to the continued immigration of families to the U.S. and the continued increasing number of students enrolled in U.S. schools under the ELL designation. The robust influx of immigrant’s school enrollment is reflected in schools across the country as classrooms are transformed from predominantly mono-cultural and mono-lingual environments to multi-cultural and multi-lingual ones. Unfortunately, the national average graduation rate for ELLs is a much lower than native-born students. The economic, social, and mental health ramifications for failing to graduate high school are dramatic; …

Centering Trans-Gender Experiences Of Marginalization, Precarity, And Representation: Developing A Theory Of Trans-Precarity, Christine E. Strayer

Dissertations

The LGBTQ+ community is commonly perceived as homogenous, affluent, and inclusive. Despite these perceptions, there is substantial evidence to suggest that trans* people, particularly those of color, experience greater levels of marginalization and precarity than gay, lesbian, and bisexual people. The purpose of this phenomenological study is to develop an understanding of how trans* people experience and navigate various forms of marginalization, precarity, and distorted public representation by implementing an intersectional framework and a transfeminist methodology. Semi-structured interviews were used to document the experiences of 34 trans* participants, ranging in age from 20-55 years. Constructed grounded theory analysis was used …

Positive Behavioral Interventions And Supports (Pbis): Does Stronger Implementation Relate To More Equitable Student Outcomes In School Discipline?, Stephenie C. Bruce

Dissertations

For this study, I explored the degree of implementation of the Positive Behavioral Interventions and Supports (PBIS) framework and the existence of disproportionality of formal school disciplinary responses to behavioral occurrences by race/ethnicity, sex, special education status (SPED), and socioeconomic status (SES) of students. Further, I investigated the relationship between a school’s degree of implementation of PBIS and the existence of disproportionality by race/ethnicity, sex, SPED, and SES, and investigated the differences in the existence of disproportionality in schools that fully implemented PBIS and schools that did not fully implement PBIS.

Literature exists on PBIS implementation and, separately, on the …

A Discipline In Search Of A Voice: A Corpus Linguistic Study Of Evaluation Scholarly Literature, Aaron Wilson Kates

Dissertations

Linguists use the concept of discourse community (DC) to describe the speech of groups of people associated by some extrinsic purpose or interest (Swales, 1990). One defining feature of a DC is a shared lexicon. Scriven (1994), in his discussion of evaluation as a discipline, addresses the need for evaluation to have a “core subject” which would then allow, among other things, the development of “concepts and language to deal with core problems,” while noting that there exists a definite lack of clarity of language among evaluators (p. 147). Christie and Rose (2003) suggest that the lack of clarification around …

Gender Quotas And Women's Substantive Representation In The National And Local Governments Of The Dominican Republic, Marcial Amaury Pineda Moquete

Dissertations

Although women's political representation has increased during the first part of the twenty-first century, the number of female politicians in legislative assemblies worldwide remains low. When well-designed and enforced, gender quota laws can increase women's representation. In tum, the election of female politicians brings about better outcomes for women. Further, female politicians elected by quota are likely to feel more committed to representing women than counterparts elected without quotas. This study tests whether and how quota-elected women can represent women's interests better than men and women elected without quotas. Using the rare natural experiment of the Dominican Republic's Congress and …

Obstacles To The Implementation Of Criminal Justice Reform, Matt Allen

Dissertations

Mass incarceration or overincarceration has gained significant attention over the last two decades, and criminal justice reform seeks to address it. This study uses constructivist grounded theory to examine the implementation of criminal justice reform legislation in Mississippi. Mississippi was chosen as the study setting because the state has been recognized as a national leader in enacting reform legislation and it has one of the nation’s highest incarceration rates. It is well established that policy implementation affects outcomes. Therefore, if the policies Mississippi is implementing are effective and they are implemented correctly, it stands to reason the state could benefit …

The Effects Of Cost, Level Of Safety, And Severity Of Injury On Manager Decisions To Implement A Safety Solution, Jonathan M. Hochmuth

Dissertations

Workplace injuries continue to be a source of substantial human and financial costs each year. Behavioral safety processes have been effective in reducing workplace injuries by increasing safety-related behaviors. In recent years, the focus in behavioral safety has shifted towards the role of managers in establishing and maintaining safe behaviors and conditions in the workplace. Understanding how managers make decisions to allocate resources is critical to improving safety. The field of behavioral economics has developed methods for studying decision-making. While there have been calls to apply these methods to occupational safety, there are only two empirical studies which have done …

Dreamers: Stories Of Daca Recipients In Higher Education During The 2018-2021 Political Climate, Alicia Billini

Dissertations

Immigration has been a longstanding conversation, or debate, in American politics and society throughout history. Whether, or how much, to embrace immigrant populations into U.S. society has been a source of polarization over time, specifically as related to the handling or treatment of undocumented immigrants. A particularly acute dimension of this issue in the United States is the question of undocumented immigrants who were brought into this country as children illegally by their parents (Council on Foreign Relations, 2021). Efforts to address the needs of this unique population of immigrants have been caught between the historically and widely divergent values …
