Who Mediates Matters: The Impact Of Individual Mediator Competency Skills On Individual And Civil Conflict Mediation, Erin V. Rowland

Doctoral Dissertations

Until this point, research in the field of conflict mediation concerning how third-party entities impact mediation outcomes has largely focused on the macrolevel factors of those entities and the disputing parties – geographic proximity of the mediating states to the disputants, the presence of alliances, the existence of enduring rivalries, etc. However, even when macrolevel factors are relatively similar, differences still exist in mediation outcome. This research proposes that some differences in mediation outcome are due to the impact of individual mediator factors, more specifically individual mediator competency skills in the form of Knowledge, Know-how, and Behavioral competencies. Borrowing from …

Critical Political Thinking: An Analysis Of Undergraduate Students’ Higher-Order Thinking Skills And Preferred Political Values, Labels, And Leadership Traits, Maya Mingo

Evaluating The Impact Of Brief Electronic Professional Development On Emotional Intelligence And Burnout Among In-Service Educators, Michelle Fast

Doctoral Dissertations

To determine the impact of an intervention to improve emotional intelligence (EI) and reduce burnout in educators, 48 in-service educators were randomly assigned to a control or experimental group and administered the Scales of Emotional Functioning: Educators (SEF:ED; McCallum et al., 2019) and the Maslach Burnout Inventory – Educators Survey (MBI-ES; Maslach et al., 2016) before and after intervention. The control group served as a waiting control and completed these instruments again after receiving the intervention. 70% of the participants noted the intervention “helped [them] manage [their] classroom,” though repeated measures ANOVAS yielded little evidence to support this characterization. No …

Local Control Over Education: Perceptions Of Tennessee And Florida County School Board Members, Joseph G. Jarret

Doctoral Dissertations

Historically, local boards of education have been viewed as community stewards who are responsible for providing local children with a quality education that reflects the values and mores of the locality in which they serve (Rice, 2014). However, in recent years, many states have significantly expanded their roles in public education. Quite often, this expansion results in an erosion of local control. For instance, in 2019, the State of Florida, which presently has a mix of elected and appointed school superintendents, considered a state constitutional amendment which would have moved the state to a wholly appointed school superintendent model. In …

Exploring Potential Impacts Of Connected And Automated Vehicle Technologies, Iman Mahdinia

Doctoral Dissertations

Connected and automated vehicle technologies have the potential to significantly improve transportation system performance. In particular, advanced driver-assistance systems (ADAS), such as adaptive cruise control (ACC), cooperative adaptive cruise control (CACC), pedestrian crash prevention (PCP) system, and advanced automated collision notification (ACN) system may lead to substantial improvements in performance by decreasing driver inputs and taking over control of the vehicle. The main questions that might arise are 1) how we can quantify the potential environmental and safety impacts of these technologies and 2) what the potential for these technologies is to address some of the important transportation-related problems. Due …

School Counselors’ Lived Experiences In Supervision, Leigh Bagwell

Doctoral Dissertations

Supervision for practicing school counselors is integral to their professional growth and development (ASCA, 2019a). This is delivered through three modes of supervision as administrative, programmatic, and clinical with researchers identifying administrative as the most prevalent mode of supervision delivered as evaluation by school administrators (Perera-Diltz & Mason, 2012). However, school counselors have stated that they want access to programmatic and clinical supervision (Sandifer et al., 2019). Derived from a synthesis of the related literature, a Suite of Supervision (SoS) was proposed that integrated the three modes, identified appropriate supervisors, and provided focus areas for professional growth and development through …

Am I Stigmatized? An Experimental Examination Of High-Status Experiences Of Stigma., Christopher F. Silver

Doctoral Dissertations

Stigma is a highly researched aspect of social psychology primarily focusing on outgroup perceptions of stigma or the behaviors associated with high-status individuals toward low-status individuals. Two studies sought to explore high-status perceptions of perceived stigma, focusing on the common variables associated with stigma within low-status groups. This was to address a growing perception among high-status individuals that they experience stigma given their identity. As a focus, this study sampled White Males (Study One) and Christians (Study Two) from the United States. As part of experimental manipulation, we presented participants with three potential conditions. Condition one where participants read an …

Benevolent Patriots? Public Service Motivation Theory In A Military-Veteran Context, Jesse R. Cragwall

Doctoral Dissertations

This study expands on previous work that focused on explaining motivations for joining the military in the United States. Using the prominent theory of public service motivation (PSM) found in public administration, I surveyed American military veterans currently pursuing post-secondary education to see if this theory helps explain why people join the military in much the same way that the theory helps explain why people join the civil service. My research includes multiple demographics, including those who served in the different military branches within the Department of Defense; those who served active duty, reserve, and national guard; officers vs. enlisted …

A Study Of Students’ And Teachers’ Beliefs About Learning English As A Second Language In Hindi Medium Schools In India, Samir Toppo

Doctoral Dissertations

The present study is an exploration of beliefs about learning English held by English as a second Language (ESL) students and teachers from Jharkhand, India. The basic premise of the study is that the learners’ and the instructors’ beliefs about learning a language affect the learning approach, learning strategy use, personal motivation, the choice of instructional material and the instructional method. Thus, beliefs indirectly affect language learning. The assumption of this study is also that the participants in this study hold debilitative beliefs about English language learning. A mixed method research approach was used in this study. The quantitative data …

This study demonstrates how three Catholic schools continue the important role of educating students to serve others: St. Matteo Ricci High School, St. Robert Bellarmine High School, and St. John Berchmans High School. Utilizing a multi-case study of leadership practices, this research study examines the Ignatian Pedagogical Paradigm’s impact on school leaders who promoted religious inclusivity. The study similarly highlights the challenges in promoting religious inclusivity. This research illustrates how the school leaders infuse their spiritual values into the school community to …

Sex Or Sexual Assault? Critical Media Literacy As A Tool For Consent Education, Riana S. Pella

Doctoral Dissertations

Most children’s exposure to media begins in infancy and increases into adulthood. Even programming produced for children is rife with sexist and racist messaging (Harris, 2018). Because of its seductive imagery, media act as a highly influential form of sex education. Problematically, media habitually portray nonconsensual behavior as sexy and consent-seeking as unsexy (Katz, 2019). Black women are routinely devalued, hypersexualized, and exoticized in movies and television (Donovan, 2007). The result of such media exposure is that young people often misunderstand what constitutes sexual assault (Edwards, 2015). Logically, when individuals do not clearly understand the differences between consensual sex and …

Early Childhood Special Education Teachers’ Attitudes Toward Inclusion: A Qualitative Study On A School’S Transition From Segregated Classrooms To More Inclusion Classrooms, Shally Moua

Doctoral Dissertations

Inclusion has been a topic of interest in education and a great deal of research has identified teachers’ attitudes as a barrier to inclusion. Therefore, using the model of attitude (Eagly & Chaiken, 1993) and inclusive pedagogy framework (Florian & Black-Hawkins, 2012), the qualitative study aims to: (1) examine the attitudes of early childhood special education (ECSE) teachers toward inclusion as a school shift from segregated to more inclusive classrooms, (2) explore types of support they received and how that support shaped their inclusive pedagogical practices to teach in inclusive classrooms, and (3) identify barriers that impact their transition to …

Effects Of Static And Dynamic Visuals On The Learning Of Science Concepts In The Secondary-School Classroom, Theodore Johnson

Doctoral Dissertations

The current study is grounded in the cognitive theory of multimedia learning. The investigator considered how embedding science text with visuals could affect secondary-school students' ability to retain the information they learn (rote learning) and transfer the new knowledge to an unfamiliar problem (meaningful learning). Furthermore, this study explored how the type of visuals (static versus vs. dynamic visual) and text (audio vs. print) affect science learning. The data generated was sourced from student participants in a secondary-school biology classroom. The purpose of this study was to investigate how prior knowledge and the integration of information modalities (i.e., text, audio, …

Effects Of Transformational Leadership On Safety Performance In The United States Commercial Trucking Industry, John Francis Mcmahon

Doctoral Dissertations

The purpose of this study was to research whether the leadership styles of safety professionals, supervisory and management leaders of commercial trucking companies, were related to their companies’ safety ratings. The theoretical framework employed in this study was based on the full range leadership model of Avolio and Bass (1991). Sixty-two long-haul commercial truck drivers participated in the study. This quantitative research was a quasi-experimental, correlational study comparing leadership styles with safety indices of trucking companies. The leadership styles were determined using the 45-question Multifactor Leadership Questionnaire (MLQ) Rater Form (Avolio & Bass, 1991) and compared them to the safety …

This quantitative, ex post facto study utilized existing data from the 2018 Teaching and Learning International Survey (TALIS), sponsored by the Organization for Economic Cooperation and Development (OECD). Descriptive analyses provided a snapshot of current collaborative action-taking and instructional practices supportive of SEL across U.S. schools among lower secondary teachers (grades 7-9). Correlational analyses identified the relationships between the independent variables, types of teacher collaborative action-taking, and the dependent variables, specific instructional practices …

Social Measurement And Causal Inference With Text, Katherine A. Keith

Doctoral Dissertations

The digital age has dramatically increased access to large-scale collections of digitized text documents. These corpora include, for example, digital traces from social media, decades of archived news reports, and transcripts of spoken interactions in political, legal, and economic spheres. For social scientists, this new widespread data availability has potential for improved quantitative analysis of relationships between language use and human thought, actions, and societal structure. However, the large-scale nature of these collections means that traditional manual approaches to analyzing content are extremely costly and do not scale. Furthermore, incorporating unstructured text data into quantitative analysis is difficult due to …

Modeling Portfolios Of Low Carbon Energy Generation Under Deep Uncertainty, Franklyn Kanyako

Doctoral Dissertations

In the 2015 Paris Agreement, nearly every country pledge through the Nationally Determined Contributions (NDCs) increased adoption of low carbon energy technologies in their energy system. However, allocating investments to different low carbon energy technologies under rising demand for energy and budget constraints, uncertain technical change in these technologies involves maneuvering significant uncertainties among experts, models, and decision-makers. We examine the interactions of low carbon energy sources (LCES) under the condition of deep uncertainty. Deep uncertainty directly impacts the understanding of the role of low carbon energy technologies in climate change mitigation and how much R&D investment should be allocated …

Mental Health And Adiposity: The Effects Of Racial Discrimination And Social Relationships, Nicole D. Fields

Doctoral Dissertations

Excess adiposity is associated with increased risk of cardiovascular disease, type 2 diabetes, and premature mortality. It is well-documented that Black women are disproportionately affected by excess adiposity. Research has focused on lifestyle factors, such as diet and physical activity, to explain the higher prevalence of obesity among Black women compared to white women; however, there is much less research on the association between psychological distress and adiposity, which may be important for understanding racial disparities. To date, no studies have examined the social context by which mental health and physical health are related. Black women in U.S. society live …

Grammars Of Identity: Political Languages Of Activism In Argentina And The United States, Ana M. Ospina Pedraza

Doctoral Dissertations

In recent history, democratic popular assemblies have played a significant role in political organizing worldwide. Contemporary theorists and social movement scholars see a global ethos of collective action in the growth of the assembly form. This dissertation studies the language of collective action in two movements that illustrate the global significance of assemblies: the neighborhood assemblies of Buenos Aires in 2002 and the New York General Assembly of Occupy Wall Street in 2011. These movements were connected by transnational networks of activism and a commitment to internal democracy now prevalent in the global left. This research asks two questions: what …

Computational Approaches For The Multimodal Imaging Of Nanomaterials And Their Biochemical Effects, Laura J. Castellanos

Doctoral Dissertations

Nanomaterial delivery systems constitute a group of drug delivery vehicles that have been used extensively in biodelivery. The proper characterization of the therapeutic function of these nanomaterials requires analytical methods to track the presence of the cargo and its biochemical effects. In some cases, the detection of the cargo and biochemical changes are not attainable in the same experiment, and more than one technique might be needed for the proper analysis of the drug delivery system. In this case, separate analysis of adjacent tissue sections is performed by techniques that offer complementary information such as MALDI-MS and LA-ICP-MS. However, the …

Targeting Drones: Framing, Vetting, And Power In Transnational Advocacy Issue Networks, Alexandria J. Nylen

Doctoral Dissertations

Existing international relations literature shows that coherent messaging by advocacy networks is a key component for successful transnational mobilization around human security issues. However, traditional models of transnational advocacy do not fully explain how activists working against armed drones have mobilized over the past two decades. This dissertation explores the case of a transnational advocacy coalition that – despite efforts to do so – was unable to coalesce around a central message: the anti-drone issue network. I ask two interrelated questions: 1) Why have international anti-drone activists not been able to overcome disagreements over framings? and more broadly, 2) How …

Financing Public Higher Education In Afghanistan: Alternative Sources And Options, Hassan Aslami

Doctoral Dissertations

Adequate financing is key to achieving the priority goals of higher education – access, quality, and relevance. In Afghanistan, the demand for higher education has increased remarkably while public higher education institutions still rely heavily on inadequate government funding. In addition, the constitutional provision guaranteeing free higher education up to the bachelor’s level in public institutions, the overall weak economy of the country, and the lack of institutional autonomy, contribute to financial austerity in public higher education institutions. This study explored alternative funding sources and options for financing public universities in Afghanistan. An integrated theoretical framework guided this study as …

Numerical Modeling Of Advanced Propulsion Systems, Peetak P. Mitra

Doctoral Dissertations

Numerical modeling of advanced propulsion systems such as the Internal Combustion Engine (ICE) is of great interest to the community due to the magnitude of compute/algorithmic challenges. Fuel spray atomization, which determines the rate of fuel-air mixing, is a critical limiting process for the phenomena of combustion within ICEs. Fuel spray atomization has proven to be a formidable challenge for the state-of-the-art numerical models due to its highly transient, multi-scale, and multi-phase nature. Current models for primary atomization employ a high degree of empiricism in the form of model constants. This level of empiricism often reduces the art of predictive …

Shifting To Critical Empathy: Exploring The Ideological Becoming Of Secondary Teachers During Critical, Dialogic Professional Development, Maria Mcsorley

Doctoral Dissertations

The limited research concerning empathy within secondary education continues to focus on student empathy, rather than shifting the gaze to teacher empathy. Moreover, while teacher empathy is generally conceptualized as an innately positive quality, skill, or disposition, the research (while limited) suggests that empathy without deep understanding of social and structural inequity has demonstrated risk. Teachers who, for example, develop and express empathy across lines of difference without knowledge of systemic inequality (particularly about how inequity shows up in schools) have the potential to oversimplify or overidentify with an “other’s” experience (Boler, 1999). This can lead to the false confirmation …

Indigenous Impositions In Contemporary Culture: Knotting Ontologies, Beading Aesthetics, And Braiding Temporalities, Darren Lone Fight

Doctoral Dissertations

This work covers Indigenous philosophy, history, aesthetics, ethics, axiology, pedagogy, temporality, and language. This is the necessary result of a central but implicit claim made throughout the project, which is that any exploration of Indigenous culture that does not work within such a multi- and inter-disciplinary approach and instead parses and isolates these elements from each other runs the risk of attenuating the complex-systems features of the Indigenous culture it examines. Indigenous cultures are a processual holism. I offer here a piece of cultural analysis/synthesis that is Indigenous from the inside and, as such, does not neglect philosophical foundations. Rather, …

Merging Ecology And Earth System Modeling: Biotic And Abiotic Controls Drive Soil Carbon And Nitrogen Cycling In Microbial-Explicit Soil Biogeochemistry Models, Emily Kyker-Snowman

Doctoral Dissertations

Ecological processes drive terrestrial biogeochemistry, yet the incorporation of ecology into the Earth system models that we use to understand and project global change remains. My dissertation focuses on expediting the incorporation of ecology into Earth system models, first by laying out a roadmap from initial assessment of ecological insights to eventual ESM incorporation, and then by demonstrating this roadmap using the example of microbially- controlled carbon and nitrogen cycling in soil. The paradigm around SOM formation and loss has shifted in recent decades away from a focus on the chemically recalcitrant leftovers of litter decomposition and towards a paradigm …
