Exploring The Viability Of Variable-Design Policy Approach To Addressing Teacher Retention In Kentucky, Donald R. Smallwood

Theses and Dissertations

Teacher attrition among early- and mid-career educators threatens the stability of Kentucky's public school workforce, yet the Commonwealth has largely relied on isolated, single-lever retention strategies. This desk-based capstone evaluated the viability of a coordinated, multiple variable policy framework for improving teacher retention in Kentucky. The study identified, appraised, and synthesized evidence, including peer-reviewed studies, state and national policy reports, legislative documents, and Kentucky-specific working-conditions data. Three research questions guided the study, addressing the evidence for coordinated multiple-variable retention approaches, the evidence for each individual policy lever, and the challenges and opportunities within Kentucky's current retention landscape. Content and thematic …

Decentralized And Privacy-Preserving Intelligent Systems Via Federated Learning For Healthcare Monitoring And Financial Security, George Anim

Theses and Dissertations

The rapid expansion of data-driven methodologies in healthcare and finance is increasingly constrained by ethical, regulatory, and security requirements that limit centralized data sharing. Sensitive information—including electroencephalogram (EEG) recordings and inter-institutional financial transaction logs—remains siloed, reducing opportunities for collaborative model development and limiting generalizability across heterogeneous environments. In healthcare, epileptic seizure prediction is challenged by inter-patient variability, scarce and non-IID EEG data distributions, and the need for real-time inference on resource-constrained wearable devices. In finance, anti-money laundering (AML) detection is complicated by decentralized and dynamically evolving transaction networks, temporal-structural dependencies, limited labeled data, and information-sharing restrictions. This dissertation proposes a …

Engineering Identity And Persistence In Community College Students, Joseph Anthony Minutolo

Theses and Dissertations

As our society becomes more technologically advanced, the need for engineers grows. Academia is tasked with preparing future engineers to meet this increasing need. However, as graduation rates continue to hover around 50%, researchers have begun to investigate what aspects of the student experience have a positive effect on the retention of engineering students. One researched topic is the relationship between engineering identity and persistence. Engineering Identity is rooted in the theoretical framework of Identity Theory, whereas Persistence is grounded in Expectancy-Value Theory. Previous research has shown a positive correlation between engineering identity and persistence among traditional university engineering students; …

Designing A Measure Of County-Level Food Access, Logan Mattingly

Theses and Dissertations

Equitable access to food is a central component of food security and a key determinant of health. Yet current approaches to food access measurement remain fragmented and limited. This study introduces the first of its kind data driven, multidimensional, county-level measure of food access in the United States. Drawing on publicly available data, I employ a factor analysis pipeline to construct a suite of latent variable estimates that represent pillars of food access. This model-based approach allows synthesis of these diverse measures into the resulting Food Access Index (FAI), while explicitly accounting for measurement error and addressing missing data. Resulting …

A Comprehensive Approach To Cognitive Offloading, Oscar Daniel Ramirez Perez

Theses and Dissertations

Learners use a variety of strategies to engage with real-world learning material. One such strategy is cognitive offloading: the reliance on external stores to alleviate internal cognitive demand. Past research has found that learners remember less when they study with the expectation of access to an external store during a subsequent test relative to when they study without that expectation. One proposed theory is the study effort hypothesis: when learners expect access to an external store, they reduce their encoding effort based on the belief that their internal memory of the information will be less important when they have access …

Staffing Reductions, Visitor Sentiment, And Recreation Demand In U.S. National Parks, Rebekkah Adicoff

Theses and Dissertations

Staffing changes in U.S. national parks have the potential to influence both visitor experience and recreation demand. This study examines how an abrupt system-wide staffing reduction affected visitor sentiment and visitation across the National Park System, while accounting for differences in park-level risk exposure. Using the February 2025 staffing reduction as a quasi-natural experiment, the analysis combines monthly park-level visitation data with TripAdvisor visitor reviews from January 2024 to August 2025. Sentiment scores derived from reviews measure perceived experience quality, while recreation demand is modeled using fixed-effects count models (Poisson and negative binomial) that control for seasonality and park characteristics. …

Explicit Writing Instruction Across Content Areas: A Professional Development, Bethany B. Richardson

Masters Projects

Research shows that writing instruction has diminished in the elementary classroom due to high stakes testing in reading and math.  Writing is a driving force for literacy achievement and should be prioritized.  In order to improve writing instruction, teachers need professional development in explicit instructional strategies for writing in other content areas.  According to cognitive processing theory, students are using multiple cognitive and metacognitive processes to complete a singular writing task.  Using scaffolds like write alouds, mentor texts, and graphic organizers can help teachers support students in their writing. Scaffolding theory suggests that students need high levels of support in …

Public Defenders’ Challenges Representing Erroneous Prosecution Cases In The Black Community, Kayla Kristine Stephens

Walden Dissertations and Doctoral Studies

Public defenders in a southern state continue to face significant challenges when representing Black individuals in the criminal justice system, particularly in cases involving erroneous prosecution. These challenges are intensified by high caseloads, limited funding, and systemic inequities, which can be stressors affecting the prosecutors wellbeing and hinder the provision of adequate legal representation. Public defenders, appointed to represent indigent defendants, frequently navigate complex legal and social circumstances that intersect with racial disparities in the justice system. For this qualitative study the research question was, how do public defenders perceive and manage any stresses representing erroneous prosecution cases in the …

How Racial Bias And Job-Related Stressors Impact The Prospect Of Police Misconduct, Jean Emmanuel Brutus

Walden Dissertations and Doctoral Studies

Police use of excessive force is an enduring challenge for criminal justice institutions and the public, particularly, affecting minority communities. This has contributed to diminished public confidence in U.S. policing institutions. Prior empirical studies among law enforcement officers, indicate that Black minorities have been discriminated by police officers. Stress research links social stress to mental health and identifies police brutality as an anticipatory stressor for minority groups. The purpose of this qualitative case study was to identify factors, including job-related stressors, and racial bias, that contribute to officers using excessive force, so to fill the gap in research, and develop …

Effective Leadership Strategies To Recruit And Retain A Multigenerational Workforce, Nnamdi Cajetan Onwuzulike

Walden Dissertations and Doctoral Studies

A lack of effective leadership strategies for recruiting and retaining a multigenerational workforce poses a significant challenge for organizational leaders. Failure to address the diverse needs and expectations of employees across generations can reduce employee retention, hinder organizational effectiveness, and increase operational costs. Grounded in transformational leadership theory, the qualitative pragmatic inquiry identified and explored effective leadership strategies used by some organizational leaders to recruit and retain a multigenerational workforce. Participants were six organizational leaders from large organizations in the United States with experience leading multigenerational workforces. Data were collected through semistructured interviews and secondary data from publicly available sources …

Nursing Staff’S Perception Of The Implementation Of The Obstetric Emergency Code Pink, Mareena Johnson

Walden Dissertations and Doctoral Studies

The local nursing practice problem addressed by this DNP doctoral project was the inconsistent and uneven response to obstetric emergencies within the health care setting. The purpose of this project was to evaluate the current implementation of the Code Pink protocol, identify any gaps or barriers in its effectiveness, and gather insights from nursing staff to propose refinements that would enhance its reliability and impact., The perception of nursing staff regarding obstetric emergency codes represents a critical dimension in the domain of maternal and neonatal health care, significantly influencing the efficacy of emergency responses and patient outcomes. Obstetric emergencies, such …

The Gut-Bladder Axis: How Symbiont Microbes Alter Urinary Tract Infections, Benjamin S. Olson

Arts & Sciences Graduate Student Theses and Dissertations

Urinary tract infections (UTIs) are among the most common bacterial infections worldwide. Consequently, they are one of the leading indications for antibiotic prescription. Despite the typically successful treatment of an acute UTI, recurrent infections are exceedingly common, particularly among women. Nearly a quarter of otherwise healthy women will suffer recurrent UTIs (rUTI) after a primary UTI; why these select individuals are continually afflicted is unkown. There are no successful therapeutics to treat rUTI representing a gap not just in the medical toolkit but in our understanding of why rUTI is so prevalent. There are many hypotheses for the risk factors …

A Clinical Accuracy Study Protocol For A Saliva-Based Point-Of-Care Lateral Flow Test To Assess Protective Immunity To Tetanus (Tetanus Study), H F Kwok, R Agarwal, Y Takwoingi, Semukunzi H, C Umuhoza, A Richter, J Nyombayire, C M Muvunyi, J Heaney, C A Green

Faculty, Staff and Students Publications

Introduction: Despite the availability of a safe and effective vaccine, 2000-3000 neonates die of tetanus yearly, predominantly in low- to middle-income countries (LMICs). Inaccurate coverage estimates and vaccination records, together with variability in vaccine response, make identifying individuals who lack protective immunity and may benefit from vaccination difficult. A more direct measure of protective immunity is widely accepted as anti-tetanus IgG concentration at or above 0.1 IU/mL. This study aims to evaluate the performance of a novel saliva-based point-of-care lateral flow test (CIS-IMMUNE Tet) for the binary classification of tetanus protective immune status (protected/unprotected) against WHO threshold-based classification of IgG …

Shared Equity Leadership In An Offshore Medical School: Distributing Responsibility For Equity, Vishal B. Surender, Sreekrishna Penna, Oluwabusola Osimosu

Journal of Comparative & International Higher Education

This essay applies the Shared Equity Leadership (SEL) framework to an offshore MD program at a private Caribbean medical school where students complete basic sciences on an island and clinical clerkships across multiple international sites. Using SEL scholarship and de-identified institutional data, we ask how equity work is currently distributed, where gaps emerge in assessment, remediation, and mobility for historically underrepresented students in medicine, and how responsibility for equity might be more deliberately shared. The Woven model of SEL provides a lens to map existing structures like curriculum committees, CQI dashboards, advising systems, and clinical site partnerships. We propose a …

Reimagining Global Dei Through Adaptive Leadership: A Framework For Advancing Racial Equity In International Higher Education Partnerships, Briana C. Edwards

Journal of Comparative & International Higher Education

Abstract

As internationalization in higher education expands through transnational research, global curricula, humanitarian training programs, and faculty mobility, discourses on diversity often remain Western-centered and detached from lived realities of structural inequity. This paper argues that adaptive leadership, grounded in mobilizing communities to confront systemic challenges in complex and uncertain environments, provides a useful pathway for rebuilding global DEI with racial equity at the center (Heifetz et al., 2009). Drawing from practice-based insight in global health, humanitarian workforce systems, HBCU models of global engagement, and higher education HR structures, the paper interrogates how colonial legacies, racial hierarchies, anti-DEI political climates, …

Knowledge Dilution And Tinted Pedagogical Dissemination: A Call For De-Colonizing Commercial Textbooks In Teacher Education For International Students, S. A. N. Zaidi, Cherian, F.V.

Journal of Comparative & International Higher Education

Abstract

This qualitative study examines how commercially produced textbooks mediate professor agency and shape the racialized and epistemic positioning of international students within a Canadian Teacher Education program. Situated within the internationalization of higher education, the study interrogates how textbook-driven curricular practices reproduce racial hierarchies, Eurocentric knowledge systems, and epistemic exclusion. The study responds to ongoing debates on race, racism, and racialization by examining how knowledge production and dissemination in classrooms may marginalize the lived experiences and intellectual contributions of international and racialized students. Data were collected through semi-structured interviews and document analysis in programs serving racialized and international students. …

Resistance, Rebuttal And Risk: Exploring Black International Students’ Perceptions Of Racial Justice Organizing In Western Canada., Prof-Collins Ifeonu

Journal of Comparative & International Higher Education

Based on 40 interviews, this study develops a three-fold typology that captures the heterogeneous nature of Black international students’ political engagement. Drawing on diasporic consciousness, I show how students negotiate their relationship to racial justice movements through race, ethnic identity, nationality, and temporary legal status. The findings underscore the need for a more nuanced understanding of Black students’ political subjectivities and brings attention to the incessant striving for personal belonging that these students undergo in their experiences of foreign study.

Contradiction And Critical Consciousness: Engaging Canadian University Students In Racial Dialogue On Anti-Chinese Racism, Dan Cui

Journal of Comparative & International Higher Education

This study examines how Canadian university students perceived and engaged with anti-Chinese racism during the COVID-19 pandemic. Drawing on grounded theory and interviews and written reflections from 28 undergraduates at a predominantly White university, the study analyzes students’ contradictory understandings of racism shaped by media, national narratives, and prior educational experiences. Informed by Bourdieu’s concept of habitus, it conceptualizes these tensions as a contradictory racialized habitus, in which awareness and denial, empathy and distancing, coexist. Three themes emerged: contradictory orientations toward anti-Chinese racism, the transnational influence of U.S. political discourse, and the limited transformative impact of a social justice course. …

Old Wine New Bottles: Racial Microaggressions Experiences Of Black African International Students In England, Solomon A. Zewolde

Journal of Comparative & International Higher Education

Despite increasing attention to inequality in higher education, the everyday experiences of Black students and how they navigate racialized environments remain underexplored. This study examined Black African international undergraduates’ experiences of racial microaggression and their coping strategies in the context of higher education in England. Drawing on Critical Race Theory, a qualitative approach was used to analyze the accounts of 16 undergraduates studying in 11 English universities.  Findings indicate that students experienced racialized challenges along two interrelated dimensions: identity-based marginalization (including assumptions of poor/inferior previous education in Africa and pathologizing discourse) and social exclusion (including devaluation of classroom contributions, invisibility, …

Inter(Sectional)(National): Modeling Belonging And Campus Climate Among Asian International Students’ Identities, Yun-Han Weng, Ionell Jay Terogo, Laura S. Dahl

Journal of Comparative & International Higher Education

International students’ belonging in U.S. higher education is shaped by institutional climates that are both racialized and internationalized, yet few quantitative studies model these dimensions simultaneously. Using data from the Assessment of Collegiate Residential Environments and Outcomes, we examine how campus nationality and racial climates relate to Asian international students’ sense of belonging, and whether these relationships vary by intersecting identities. We examine how campus nationality and racial climates relate to Asian international students’ sense of belonging (n = 763). Measurement model comparisons empirically supported a two-factor solution separating nationality and racial climates once reverse-worded items were removed for improved …

“It’S Very Racialized And Very Politicized”: International Educators Recount The Campus And Local Climate For International Students, Amanda R. Corso, Gaurav Harshe, Chrystal George Mwangi, Christina W Yao

Journal of Comparative & International Higher Education

International educators have served as the primary support system for international students and are responsible for supporting international students through navigating racist encounters often without feeling adequately prepared (George Mwangi et al., 2025; Yao et al., 2019). With a diverse learning environment model as our framework, our study explored how international educators in the United States make sense of their racialized local and campus contexts, specifically in their work with international students. Using a three-dimensional approach to narrative inquiry, we interviewed 31 participants from New York, Massachusetts, California, and Michigan who worked in international student and scholar offices. Our findings …

Not Quite Foreign, Never Fully Belonging: Racialization Of Southbound Policy Students In Taiwan, Garima Jha

Journal of Comparative & International Higher Education

This paper critically examines how race and racialization shape the socio-cultural adjustment experiences of international students from New Southbound policy (NSP) countries in Taiwan. Drawing from a qualitative part conducted for my master’s thesis, which explored the coping strategies and adjustment processes of seven students from Southeast and South Asia through semi-structured interview, I reframe the data to center race as an analytical lens using the conceptual framework proposed by Glasgow (2009) which explains that racialization as the process through which social meanings are attached to perceived cultural or bodily differences, creating and maintaining hierarchies among groups. and Brondolo et …

Transnational Racialization: An Exploratory Case Study Of Asian International Students In U.S. Higher Education, Jia Zheng, Kristyn Lue

Journal of Comparative & International Higher Education

This exploratory case study examines the transnational racialization experiences of 14 ethnically diverse Asian International Students (AIS) studying abroad in the U.S. Using International Student Critical Race Theory to foreground the contexts of participants’ home countries, we ask: What are AIS’s experiences with transnational racialization? Findings suggest that AIS are socialized to the racial dynamics of the U.S. through: (1) the different contexts of their home countries, (2) their specific social positioning within these contexts, (3) the influence of Western narratives across the globe, and (4) their academic communities in the U.S. Our findings advance theoretical perspectives on racialization in …

Resurrecting Anti-Apartheid Solidarity: Scholasticide, Race, And The Politics Of Internationalization In Higher Education, Divinia Jithoo, Alia Gilbrecht

Journal of Comparative & International Higher Education

This paper interrogates how racialized internationalization and epistemic injustice shape global higher education through a comparative critical analysis of South African and Palestinian academic resistance. Drawing on decolonial theory (Du Plessis, 2021) and Fricker’s (2007) framework of epistemic injustice, we examine how scholasticide—the deliberate destruction of Palestinian educational institutions—reveals higher education as a targeted site of racialized domination rather than a neutral casualty of war. Our findings show that normalization, sustained through Global South partnerships with Israeli institutions, functions as a racialized mode of internationalization that obscures complicity in settler-colonial violence. These dynamics are reinforced by transnational anti-Palestinian racism, a …

Inclusions And Illusions: Transnational Matrix Of Subordination & The (In)Visible Hierarchies Among Racialized International Students In Ontario Universities, Shamiga S. Arumuhathas

Journal of Comparative & International Higher Education

This study critically examines the (in)visible racial hierarchies experienced by racialized international students (IS) within Ontario’s (HE) education landscape amid populist, anti-immigration backlash and expanding internationalization. Guided by Critical Race Theory (CRT) and intersectionality, this research employed narrative inquiry with 14 self-identified racialized IS at 2 public universities. Core research questions include: How do racialized IS experience belonging, racism, and institutional EDID (Equity, Diversity, Inclusion, Decolonization) in present-day Ontario? How do EDID and internationalization policies obscure or reinforce racial hierarchies? Findings reveal a transnational matrix of subordination: White IS remain proxies for institutional belonging, while racialized and domestic students act …

Decolonizing Raciolinguistic Ideologies In Institutions Of Higher Learning, Chantelle M. August-Mowers, Samantha M. Hoffman

Journal of Comparative & International Higher Education

This article examines how raciolinguistic ideologies shape global higher education (HE), highlighting the intersection of language, race, and systemic inequalities. English often functions as a gatekeeper, privileging certain knowledge systems while marginalizing students and faculty from the Global South (Flores & Rosa, 2015; Pennycook, 2007). Structural inequities persist in faculty recruitment, international student selection, and academic publishing, reflecting colonial legacies and epistemic injustice (Canagarajah, 2013; Quijano, 2000). Racialized and linguistically marginalized students experience exclusion, microaggressions, and limited mobility, revealing contradictions between diversity rhetoric and institutional practices (Sekaja, 2022; Enslin, 2024). The study advocates decolonial and multilingual interventions, including translanguaging, inclusive …

Case Study - China Airlines Flight 006, Jaxon Daniels, Ryan Lutwin, Jacob Patterson, Elizabeth Bosan, Ronyn Orrell

Discovery Day - Daytona Beach

On February 19, 1985, China Airlines Flight 006, a regularly scheduled flight from Taipei, Taiwan, to Los Angeles, California, experienced a serious in-flight upset while cruising at high altitude. The aircraft subsequently entered a steep, uncontrolled spiral dive, during which it experienced extreme G-forces and sustained structural damage. After regaining control, the crew diverted the aircraft to San Francisco International Airport, where it landed safely (National Transportation Safety Board, 1986). The Human Factors Analysis and Classification System (HFACS) framework helps to identify and analyse the organizational elements and conditions that lead to aviation accidents (Small, 2020). Aviation accidents are not …

Fatigue And Circadian Disruption In Long-Haul Ferry Pilots: Human Factors Challenges And Mitigation Strategies, Parneet Makkar

Discovery Day - Daytona Beach

Fatigue and circadian rhythm disruption present significant human factors challenges in long-haul aviation operations, particularly for ferry pilots (pilots responsible for transporting aircraft long distances between locations) who often travel across multiple time zones before beginning flight duties. Circadian rhythms regulate the human sleep-wake cycle and are closely tied to cognitive performance, alertness, and coordination. Rapid travel across time zones can disrupt these rhythms, producing symptoms commonly associated with jet lag such as sleep disturbances, fatigue, and reduced cognitive functioning. For ferry pilots, long travel periods and irregular schedules may increase the likelihood of fatigue before flight operations even begin. …

Effects Of Human-Animal Interaction On Positive Youth Development: A Replication Study, Allison Pachunka, Jay Jeffries, Lisa Karr, Lena Luck, Bryan A. Reiling, Douglas H. Schultz, Jeffrey R. Stevens

People and Animals: The International Journal of Research and Practice

Interacting with animals can improve health and well-being across the lifespan. Some programs such as 4-H and FFA center around youth interacting with animals, potentially enhancing youth development. Mueller (2014) investigated whether these interactions and attitudes about animals influenced measures of positive youth development. The aim of our studies was to replicate Mueller’s methods and extend her work by evaluating whether membership in animal-focused youth programs moderate associations between interactions, attitudes, and positive youth development. We did not find strong relationships among human–animal inter-action and positive youth development, which failed to replicate Mueller’s findings. However, we did find relationships between …
