Impact Of The Regionalization Of Universidad De Antioquia In The Development Of Human Capital And Improvement Of The Equity In The Region Of Urabá, Monica Castaño Mejía

Dissertations

Problem

In Colombia, higher education plays a relevant role in developing human capital and equity, giving everyone the opportunity to access higher education. In particular, the government has been supporting public and private universities to open campuses in rural areas where guerrillas, the mafia, and paramilitary groups were fighting the government to dominate the territories. In 1995, the government of the State of Antioquia officially established the regionalization of higher education as a strategy to promote higher education in disadvantaged regions. The Universidad de Antioquia (Universidad de Antioquia) adopted that strategy as part of its development plans during the last …

The Body Of Christ And The Law: A Comparative Study Of Romans 7:4 And Galatians 2:19, Dominic Bornand

Dissertations

In Romans and Galatians, Paul refers to a spiritual death to sin (Rom 6:2) and to the law (Rom 7:4; Gal 2:19). As the means of the believer's death to the law, Paul mentions the "body of Christ" in Rom 7:4 and the "law" in Gal 2:19. These verses seem to suggest some sort of relationship between the body of Christ and the law, as well as between the law and sin. The purpose of this study is to determine the type of relationship between the body of Christ and the law, as well as between law and sin. The …

The Perceived Results Of Feedback And Evaluation Of Teaching Effectiveness On Adjunct Faculty Professional Development And Growth, Luda V. Vine

Dissertations

Problem

While full-time faculty at any institution of higher learning undergo an established system of evaluation of teaching effectiveness, adjunct faculty members' experience varies greatly from institution to institution. There is little in the relevant academic literature about an effective feedback mechanism for evaluating teaching effectiveness among adjunct faculty members. Limited qualitative research has been done to understand the effects of teaching evaluations on the professional development and growth of individual adjunct faculty members. Developing an understanding of effective evaluation of teaching that will result in improved adjunct faculty professional development and growth will impact not only the faculty members' …

Explaining Deep Q-Learning Experience Replay With Shapley Additive Explanations, Robert S. Sullivan

Dissertations

Reinforcement Learning (RL) has shown promise in optimizing complex control and decision-making processes but Deep Reinforcement Learning (DRL) lacks interpretability, limiting its adoption in regulated sectors like manufacturing, finance, and healthcare. Difficulties arise from DRL’s opaque decision-making, hindering efficiency and resource use, this issue is amplified with every advancement. While many seek to move from Experience Replay to A3C, the latter demands more resources. Despite efforts to improve Experience Replay selection strategies, there is a tendency to keep capacity high. This dissertation investigates training a Deep Convolutional Q-learning agent across 20 Atari games, in solving a control task, physics task, …

Model-Free Control Methods For Gait And Standing Push Recovery In Bipedal Humanoid Robots, Jerry Sweafford Jr.

Dissertations

This dissertation examines the use of model-free control methods in various aspects of effective balance and gait control for two-legged humanoid robots.

Trust is at a low point in American life regarding institutions in general but particularly the church. This study examined the relationship between a Southern Baptist pastor and the congregants that he serves. Specifically, a model was proposed in which perceived consistency between words and actions, perceived warmth, and perceived competence predict trust in the pastor from the congregation. To test this model, a quantitative study with a survey design was performed. A survey was created using a combination of instruments for authentic leadership, behavioral integrity, competence, warmth, and trust. The survey was distributed through digital mediums to Southern Baptist …

Professional Counseling/Psychotherapy And Its Influence On Emotional Intelligence And Authentic Leadership Development: A Qualitative Participatory Inquiry Research Study, Jenny Lee Broaddus

Dissertations

The authentic leadership theory acknowledges that leaders must advance their introspection to gain self-awareness, balanced processing, internal moral perspective, and relational transparency. Leaders may desire to lead effectively, yet modern leaders lack emotional intelligence, authenticity, and a vehicle to acquire (Northouse, 2019). Like authentic leadership, emotional intelligence is favored in leaders to include self awareness, emotional management, empathy, and relationship management (Goleman, 1995). Much research surrounds emotionally intelligent competencies in leadership, but limited research targets behaviors for development. A look at psychology and counseling revealed that self-awareness, a standard competency in authentic leadership and emotional intelligence, is also the primary …

To this end, this study applies Bolman and Deal’s 4-frame model of organizational learning lenses to school improvement indicators on the Illinois 5Essentials Survey. Through taking Bolman and Deal’s Online 4-frame Self-assessment, I am able to identify the organizational learning lens least integrated into my own leadership worldview. The organizational learning lenses that comprise Bolman and Deal’s 4-frame model are the structural, symbolic, human resource, and political lenses. I then apply core tenets of my least integrated lens …

Reconstructing The Kantian Ends Of Reason: Holiness Analytically Entailing Beatitude In An Eternal Highest Good, Anthony Gudwien

Dissertations

This dissertation argues that an eternal highest good is the final end of sensible, rational agents. This final end occurs in a noumenal world – what I have labelled World Four – that has holiness analytically entailing beatitude. However, before meritorious moral agents are incorporated into this final noumenal world, they will exist in three prior worlds. World One is our current phenomenal world where sensible, rational agents can adopt a maxim to resolutely pursue holiness. World Two, which is made possible by the immortal soul postulate, is where sensible, rational agents continue their resolute pursuit in order to become …

Edible Learning: School Food Service Programming And Experiential Education That Promote Sustainable Agriculture And Better Nutritional Health, Kristina Grasty

This peptide ligand was synthesized and …

Exploring Moral Distress Among Nurse Leaders, Preston H. Miller

Dissertations

Moral distress (MD) occurs when an individual knows the ethically correct action to take in a situation but institutional constraints prevent the individual from acting. MD is a well-documented phenomenon among nurses and occurs at a high frequency in the critical care setting. When MD is not adequately addressed and actions are not taken to mitigate precipitating factors within an organization, moral injury, moral residue, and burnout may consequentially result in nurses leaving their role or the profession. Nurse leaders are positioned to exemplify ethical leadership and provide support for their staff when MD is experienced; however, nurse leaders experience …

Latinx/a/o students make up almost half of the California Community College system’s population. However, Latinx/a/o students account for about 15% of three-year completion rates (certificate, degree, or transfer). In support of student success strategies, the literature describes the role of counselors and how they help students navigate the complexities of higher education. This mixed-methods study investigated how community college counseling practices and services are perceived by Latinx/a/o students; and which of those practices and services best supported the success of this student population. Key findings included the importance of counseling services, as well as preferred counseling appointment logistics and topics …

Never Too Young: The Existence, Impact, And Sustainability Of Ethnic Studies In Elementary School, Angela R. Guzmán

Dissertations

Ethnic Studies has existed in higher education for more than fifty years. In high school, critical education researchers have recognized Ethnic Studies as vital to improving attendance, lowering suspension rates, and boosting GPAs for BIPOC students. This has given rise to the recent K-12 Ethnic Studies model curriculum adoption by the State Board of Education, and the signing of Assembly Bill 101, making California the first state to require that all high school students complete a semester-long course in Ethnic Studies. Regrettably, Ethnic Studies continues to be mostly limited to higher education and grades 9-12 in public schools despite research …

Self-Regulation And Academic Motivation As Predictors Of Academic Achievement Of Undergraduate Students In An Online Learning Environment, Sonia Almwalad

Dissertations

Problem

Online learning is a form of distance education that occurs via the Internet (Adams, 2004; Carliner, 1999). The success of online learning depends on student-related factors such as acceptance, willingness, and motivation (Almaiah et al., 2019; Almaiah et al., 2020). When online learning systems are not utilized, students cannot realize the concomitant benefit of improved performance. Online learning has many positives, but it does present a problem when it comes to academic success. Motivation and self-regulation are two of the key factors for successful online learning given that students are subject to minimal supervision or guidance from teachers in …

An Examination Of The Influence Of Ethnic Identity, Spirituality, And Social Support As Predictors Of Resilience Among Black Male College Graduates Born In The United States, Sandy Belizaire

Dissertations

Problem

This study aimed to assess the influence of ethnic identity, spirituality, and social support on resilience among Black males (BM) who were born in the United States of America and are recent college graduates. The achievement gap between BM and their counterparts is among education's most infuriating problems. Educators are more likely to dissuade Black men from going to college, and those who enroll drop out before they graduate (Noguera 2003; Wilborn 2013).

Method

This study employed a non-experimental, quantitative correlation research design using self-report questionnaires. The target population for this study was American-born Black males who were graduates …

Teaching Shante Curtelia Dominique Ophelia Brown Johnson : An Autoethnography Of A Black Male, Seventh-Day Adventist, Jazz Avant-Garde Artist, Michael Gayle

Dissertations

Leadership is part and parcel of societies and cultures. Leadership research can provide understanding that in turn provides knowledge, resources and growth opportunities for leaders. Leadership may be understood from a personal perspective as being bound up with identity. As I examine myself as a person and as a leader, I realize that several identities are prominent: Black male identity, Christian identity, jazz avant-garde artistic identity. Each of those identities have features that contribute to leadership.

The purpose of this study is to describe and explore leadership experiences of a Black male, from the Seventh-day Adventist Christian tradition who is …

Predictors Of Statistics Anxiety Among Graduate Students In Saudi Arabia, Rabab Abdulghani

Dissertations

Problem

The problem addressed in this study is the anxiety experienced by graduate students toward statistics courses, which often causes students to delay taking statistics courses until the end of their program. Students believe that statistics courses are not essential and are the greatest obstacles to obtaining their degree. Previous theoretical models have focused on predicting student performance in statistics. However, this study aims to identify specific factors that could decrease student statistics anxiety and enhance positive attitudes and self-efficacy toward statistics. The study developed a conceptual model to predict statistics anxiety among graduate students in educational and social science …

Toward A Biblical And Missiological Framework For Transformational Advocacy In The Seventh-Day Adventist Church, Michelet William

Dissertations

Problem

Adventists have been inconsistent in dealing with inequality and injustice in society, swaying between silence, accommodation, positional statements, and direct advocacy approaches. Although advocacy has become more prominent among Adventist thinkers since the end of the twentieth century, there is a lack of empirical data which answer questions related to contemporary Adventists' beliefs and practices in relation to advocacy in the context of mission. Concomitantly, there does not yet exist a documented or articulated Adventist missiological perspective on advocacy.

Research Questions

(1) What part, if any, has biblically-based social advocacy played in Adventist mission history? and (2) What do …

Between Script And Scripture: Performance Criticism And Mark's Character(Ization) Of The Disciples, Zechariah Eberhart

Dissertations

This project reimagines a first-century reception of the Gospel of Mark within a historically reconstructed (yet hypothetical) performance event. In particular, it considers the disciples' character and characterization through the lens of performance criticism. Questions concerning the characterization of the disciples have been relatively one-sided in New Testament scholarship, in favor of their negative characterization. This project demonstrates why such assumptions need not be necessary when we (re-)consider the oral/aural milieu in which the Gospel of Mark was first composed and received by its earliest audiences. In this project, I demonstrate that despite its "relative" newness, the primary tenets of …

Dungeons & Dragons & Dewey: Toward A Ludic Pedagogy Of Democratic Civic Life Through The Philosophy Of John Dewey And Tabletop Role-Playing Games, Susan Haarman

Dissertations

In this dissertation, which uses philosophical inquiry, I posit that tabletop role-playing games (RPGs) can provide an educative experience for democratic civic life in the Deweyan tradition. Tabletop RPGs present an invaluable resource for ongoing civic formation by encouraging deliberation and consensus building across shared goals and circumstances. Philosopher John Dewey emphasized that democracy is defined by the civic habits and collective action, not formal governance structures. The experience of playing tabletop RPGs can cultivate habitus and space for future and current citizens to practice democratic skills and commitments. Therefore, these games are a means that align with the ends …

Artapanus And Greek Colonial Poetics, Scott Harris

Dissertations

The fragments of Artapanus have proven to be enigmatic for most scholars over the years and as such have not been treated in significant detail. Most scholarship has been restricted to two separate lines of enquiry: genre and ethnicity. I suggest that the resonance between Greek colonial poetics sheds new light on Artapanus's literary agenda: namely, that Artapanus is constructing and representing the memory of Jewish cultural and political foundations using broader Greek poetics which were used to describe the civic, cultic and geographic foundation of a colony. In this way, Artapanus is no longer an outlier within the Hellenistic …

Key Stakeholders' Perceptions Of Stem Education In Zambia: A Mixed Methods Inquiry, Choobe M. Maambo

Dissertations

In the recent past, the concept of STEM education has become a “buzz phrase” in the Zambian education system, and yet, very little is known about STEM education let alone what those involved in STEM think or know about STEM in the country. The primary purpose of this study was to investigate key STEM stakeholders’ perceptions of STEM education in Zambia. To better understand STEM in the country, it was critical to explore the perceptions of STEM held by STEM teachers, STEM administrators, and STEM policymakers in the perception domains of STEM vision, STEM definition, STEM purpose, STEM relevance, and …
