A Quantitative Exploration Of Public School Teachers’ Colorblind Racial Attitudes And Their Teaching Practices, Lindsey Dopheide

Dissertations

Teachers play a significant role in shaping student’s academic experiences, social development, and understanding of race and diversity within school settings. Because schools function as important sites of racial socialization, teachers’ beliefs about race may influence how they interpret student behavior, respond to inequities, select instructional practices, and engage with culturally diverse classrooms. One framework that has received increasing attention within psychological and educational research is colorblind racial ideology (CBRI) which reflects the minimization or denial of the continuing significance of race and racism in society. Colorblind racial ideology has been identified in prior literature as a dominant framework for …

Community Detection In Bipartite Networks Using Bipartite Stochastic Block Models With Node-Level Covariates, Geraldine Elaine Percival

Dissertations

In this age, monumental webs of data demands for perpetual cultivation of ways to untangle these webs of information. One of the many curiosities is how to systematically group entities. When clustering, one avenue to take is ascertaining the interconnectedness between the data points, and gauging their influence to each other. This perspective is programmed to model the relationships between the data presented as a network. Many of the methods being used today are algorithm-based, which may pose limitations in understanding and explaining the uncertainty revolving around the data. Hence, it is proposed to steer towards a model-based approach that …

Bridging The Gap: Action-Oriented Vs. Community-Minded Mentalities And Behaviors In Cold Case Investigation Units, Samantha Strine

Dissertations

One key group in policing that has seen an increase in public and media attention but not research is the cold case investigation unit. These units tend to be more “bureaucratic”, focusing on communication, community-engagement skills, and “desk work”. Thus, this is a potential area for learning techniques and policies that shift the mentalities within police culture to be more accepting of new community focused policies. This study also seeks to address a gap in current research related to studying specialized police units.

The purpose of this study is to describe the organizational dynamics and officers’ tactics, perceptions, and interactions …

America The Monstrous: The Birth Of American Horror Fiction In The Long Nineteenth Century, Rachel Kietzman

Dissertations

American gothic works that center the affect of horror explore themes of abjection, inhumanity, and monstrosity that impede a coherent expression of American identity. By approaching these works through the lens of horror rather than only as Gothic works, a picture ofa visceral, embodied becoming takes shape: America is a monstrous birth in the most literal sense of the word, a sign and demonstration that unity and uniformity are not the same, that wholeness does not require conformity, and that political choices are paid for in flesh. In short, American horror fiction is the head of Medusa, an apotropaic sign …

Examining The Relationship Between Trauma-Informed Safety Drill Practices And School-Level Chronic Absenteeism In Maine Secondary Schools, Tina Nightingale

Toward Intentional Praxis: A Design Thinking Multi-Case Study Of Cognitive-Constructive Toolkit Implementation In An Elementary Professional Learning Community, Azam Nathaniel

Dissertations

Among several learning theories that were dynamic and constantly evolving with time, cognitive and constructive theories were predominant in the field of education. However, these theories often included overlapping and contrasting concepts, contributing to confusion in terminology among teachers and limited explicit use in instructional practice. Within the context of K-12 education, teachers demonstrated conceptual awareness of cognitive and constructive learning theories; however, the theories were not a part of day-to-day conversations and were minimally identified in practice. Instead, the theories were implicitly applied as teachers balanced competing professional responsibilities, including daily routines, syllabus requirements, district standards, new initiatives, differentiated …

A Qualitative Study Of Gratitude Practice Among Won Buddhist Older Adults And Implications For Gerontological Social Work, Sungsim Lee

Using Design Thinking To Support Teacher Confidence In Delivering Culturally Relevant Literacy Instruction To Address Literacy Achievement Gaps, Amy Winters

Dissertations

Despite comprehensive efforts over the years, literacy rates in the United States continued to decline, particularly among students from disadvantaged populations. The literacy achievement gap was driven by socioeconomic disparities, inadequate teacher preparation, and a lack of access to evidence-based, culturally relevant materials. In the Main School District (MSD), the scholar practitioner identified while interventions existed, inconsistencies in literacy instruction and a lack of teacher confidence in delivering culturally responsive instruction hindered student progress. The dissertation in practice focused on addressing issues in literacy instruction and achievement while highlighting ways to meet teachers’ needs and provide means to engage all …

Attachment Style, The Working Alliance, And Client Self-Disclosure In Individual Psychotherapy, Jennifer S. Baar

Dissertations

Client self-disclosure is a core component of the psychotherapy process and increased levels of client self-disclosure have been shown to predict more positive therapeutic outcomes (Pattee & Farber, 2008; Sloan & Kahn, 2005). Similarly, the working alliance and attachment are constructs that have been studied in psychotherapy research and are consistently associated with therapeutic outcomes. Specifically, stronger working alliance ratings and higher levels of secure attachment have been found to predict more positive therapy outcomes (e.g., Flückiger et al., 2018; Mallinckrodt et al., 2005; Sauer et al., 2010). As these three constructs have been found to influence psychotherapy outcomes, the …

The Motherhood Contract: Mental Load, Moral Risk, And Gendered Care In Contemporary Parenting And Digital Culture, Stephanie J. Stallman

Dissertations

This dissertation examines childcare as a site of gender inequality shaped by cultural norms, structural barriers, and digital discourse. Despite increased awareness of shared parenting ideals, mothers predominantly bear the “mental load.” This study introduces the idea of a motherhood contract: implicit expectations that mothers are responsible for managing children’s needs. Two research questions guide this study. (1) What are parents’ experiences of managing the mental load of caregiving? How do they make sense of these experiences within the gendered and moral expectations shaping family life? (2) How are cultural ideas about childcare and parenting constructed, circulated, and reproduced through …

The Impact Of Artificial Intelligence And Neuro-Linguistic Programming On Candidate Assessment In Talent Acquisition, Amna Fahim

Dissertations

Digitalization in human resource management led to the implementation of Artificial Intelligence (AI) and Neuro Linguistic Programming (NLP) in recruitment practices.

According to the literature, this study is grounded in Technological Determinism, Machine Learning Theory, Psycholinguistic Theory, and Cognitive Behaviorism. A quantitative correlational approach was used in this study. To investigate the proposed research questions, descriptive statistics, Pearson …

The Impact Of Religious Behaviors, Islamophobia, Gender Roles, Language Proficiency, And Education Levels On Mental Illness Stigma And Help-Seeking Behaviors Among Arab Women In The U.S., Rima Muhsen

Dissertations

The official U.S. census does not provide data on the number of Arab Americans in the United States, which hinders studies that focus on this population group to explore their needs and improve access to mental health services. Arab women in America represent a subgroup that has received insufficient attention from researchers, particularly regarding culturally sensitive topics such as mental health problems and their associated stigma. The influence of cultural, social, and religious factors on self-stigma associated with mental illness has not been adequately studied among this marginalized group. While previous research has suggested a relationship between self-stigma, social stigma …

Campus Community Vibes: How Queer Asian American Students Navigate Their Higher Education Experiences, Nathan Nguyễn

Dissertations

Misconceptions and stereotypes about Asian American college students include the belief that they are innately academically successful and that if Asian American students struggle, their challenges do not compare to their Black/African American, Hispanic/Latine, or Native American/Indigenous counterparts (Museus & Buenavista, 2016). Contemporaneous to this, lesbian, gay, bisexual, transgender, and queer (LGBTQ) college students experience interrogation, exploration, and various levels of support regarding their sexuality and/or gender identity. At this intersection, queer Asian American students must navigate campus settings that can enhance or diminish their agency for different facets of their identities (Crenshaw, 1991; Iftikar & Museus, 2018; Ray, 2019). …

From Campus To Community: The Role Of Higher Education In Strengthening Regional Entrepreneurial Ecosystems In Appalachia, Anne M. Montgomery

Dissertations

This study addresses a gap in understanding how small, rural liberal arts higher education institutions (HEIs) in the Appalachian College Association Entrepreneurial Alliance (ACAEA) support regional entrepreneurial ecosystems (EEs), and how, if at all, those strategies vary across Appalachian Regional Commission (ARC) county economic classifications. Using a qualitative multi-case design, the study examined 10 ACAEA institutions and drew on semi-structured interviews, site observations, institutional documents (including strategic plans), and ARC county-level economic data. The analysis produced five cross-case themes describing how these institutions support entrepreneurship: (a) strategic leadership and institutional culture, (b) experiential and embedded entrepreneurial education, (c) community-driven partnerships …

Long-Covid And Cognition, Mychael Bruce

Dissertations

COVID-19 is an evolving virus that can harm the body’s respiratory and cardiovascular systems. Directly related to COVID-19 are individuals who do not recover from their initial infection, making them long haulers. Long-COVID is transitioning from a range of isolated phenomena to higher prevalence rates in patients who contracted COVID-19. Many individuals report issues with cognitive function, referred to as ‘brain fog’, that affect memory, attention, and even language skills. This literature review addresses the available research on Long-COVID and how persistent infection correlates with cognitive difficulties. It aims to explain the neurobiology of Long-COVID and how Long-COVID interacts within …

Exercise Therapy For Mood Disorders In Retiring/Former Athletes, Christian Antos

Dissertations

This dissertation examined the potential integration of exercise therapy and psychotherapy as a treatment approach for mood-related difficulties experienced by former elite athletes during the transition out of competitive sport. Retirement from athletics is often associated with significant biopsychosocial challenges, including disruptions in identity, healthy routines, social support, and emotional well-being. Existing literature suggests that exercise may serve as an effective adjunctive intervention for improving mood and overall psychological functioning, though limited research has explored its application among retiring athletes within psychotherapeutic contexts. This literature review synthesized current research related to athletic retirement, neurobiological mechanisms associated with physical activity, and …

Mechanics And Physical Attributes Of Nature-Based Alterations: Rock Reinforcement And Urban Heat Island Assessment, Mary Chikondi Ngoma

Dissertations

Ground improvement is critical to geotechnical and geo-engineering systems, where modification of the properties of geomaterials (rocks and soils) is required to maintain stability and prevent failure of infrastructure installed within and around them. This need has become increasingly important with rapid urbanization and population growth, which intensify demands on surface and subsurface systems and further challenge the performance of supporting geomaterials. As a result, there is growing interest in nature-based solutions, particularly biologically mediated processes such as biocementation, which can enhance the physical, hydraulic, and mechanical properties of geomaterials while offering environmentally sustainable alternatives to conventional ground improvement techniques. …

Glass Transition Temperature Of Plga Nanoparticles And The Application In Drug Delivery, Guangliang Liu

Dissertations

The glass transition temperature (T_g) of poly(D,L-lactic-co-glycolic acid) (PLGA) nanoparticles plays a crucial role in governing molecular mobility, diffusion, and consequently, drug release kinetics. However, the interaction among residual surfactant, drug effect, nanoscale confinement, and release medium on T_g remains insufficiently characterized. This study aims to bridge this gap by correlating the thermal behavior of PLGA nanoparticles with their drug release behavior under physiologically relevant conditions.

In the present study, PLGA nanoparticles were synthesized using both nano-emulsion and surfactant-free nano-precipitation approaches. The influence of residual surfactants - poly(vinyl alcohol) (PVA) and didodecyldimethylammonium bromide (DMAB) - was systematically …

Task Sharing Of Tele-Mental Health Interventions In Primary Care: Formative Assessment Using Implementation Science, Frances Chu

Dissertations

Primary care frequently cares for patients with mental health concerns. Tele-mental health (TMH) interventions are becoming used as alternatives to the traditional methods of mental health care delivery. However, implementation of these interventions has met with uneven implementation success. Task sharing is a care model that trains less specialized health care workers to perform tasks typically done by specialized health care workers. Few studies have examined the combination of Task sharing and TMH intervention for the management of mental conditions. This dissertation project utilized implementation science methodology for formative assessment of task sharing of TMH interventions. The goals of the …

Moving Toward Humanization In Education: Teacher Models In K-12 Settings, Juan Carlos Marques

Dissertations

ABSTRACT Current pedagogical initiatives—social emotional learning (SEL), restorative practices

(RJ), and positive behavioral interventions and supports (PBIS)—aim to improve students’ relationships at school, but they often fail to address the hegemonic ideologies that sustain inequitable disciplinary practices and outcomes for minoritized students. Humanization, which centers the dignity and lived experiences of children, is a needed critical component. Drawing from the work of scholars such as Freire and del Carmen Salazar, this study sought to learn from the experiences of teachers who engaged humanizing practices. Grounded in disability critical race theory (DisCrit), this study examined how teachers used a humanizing approach …
