Black Ecological Care: Conservation, Environmental Justice, And Sovereignty In Baltimore, Maryland, Alexandria Nicole Casteel

Dartmouth College Ph.D Dissertations

Dominant traditions of urban planning, municipal policy, and environmental science register Black urban spaces through a vocabulary of pathology, as sites of ecological deficit, contamination, and social decay. This dissertation investigates how Black communities in U.S. cities attend to the environment in ways that address legacies of environmental and social injustice while opening pathways toward different environmental futures. I gather these practices under the analytic of Black ecological care, which captures the generative labor of making and maintaining livable worlds within, alongside, and beyond histories of harm. I develop the analytic across twenty-nine months of ethnographic fieldwork in 2021 and …

Security-Oriented Voice Authentication Using Machine Learning, Ifeoluwa Stella Elegbe

College of Graduate Studies: Theses & Dissertations

This study develops and evaluates a machine learning and deep learning-based voice authentication system for secure identity verification.

Supporting Early Literacy In Preschool: The Influence Of Activity Settings, Shared Reading, And Teacher–Child Interactions, Megan Turnquist

All Electronic Theses and Dissertations

This literature review explores current research about the activities and settings currently in place in preschool classrooms across North America. While a majority of the preschool day is spent in whole-group and free-choice activities, research indicates that instruction provided in small groups and book reading are two important ways to harness engagement and deliver high-quality instruction. Different kinds of teacher-child interactions during book reading can support the development of crucial early literacy skills, such as vocabulary and print knowledge. While time spent on literacy content varied widely across classrooms, teachers responded well to training in both print referencing and dialogic …

Integrating Fieldwork Educators Into Didactic Coursework: Impact On Occupational Therapy Students’ Readiness For Level Ii Fieldwork, Tara Mansour, Victoria Denovellis

Journal of Occupational Therapy Education

Level II fieldwork represents a critical transition from didactic learning to clinical practice in occupational therapy education, yet students frequently report challenges related to applying knowledge, managing expectations, and navigating complex clinical environments. Many of these challenges reflect aspects of the “hidden curriculum,” including implicit expectations related to communication, professional behaviors, and feedback that are often not explicitly addressed in coursework. This study examined the impact of integrating fieldwork educator–led sessions into a didactic seminar to support student readiness. A mixed-methods survey using a retrospective pre–post design was administered to 33 students (97% response rate). Quantitative analyses demonstrated significant improvements …

From Myers To Slaughter: A Brief Theory Of The Constitutionalization Of Secondary Sources, Dana Neacsu, Paul D. Callister

Faculty Works

For more than two centuries, American constitutional adjudication has relied upon secondary sources. Yet constitutional theory has almost entirely ignored them. Originalism debates constitutional text. Living constitutionalism debates constitutional evolution. Theories of precedent debate judicial authority. None asks a more fundamental question: What role do secondary sources play in constitutional adjudication? This Article argues that the answer has fundamentally changed in the last 100 of years. Chief Justice William Howard Taft's opinion in Myers v. United States (1926) marked a constitutional revolution by transforming secondary authorities from explanatory materials into evidence of constitutional continuity. Exactly one century later, Chief Justice …

Making Words Count: Computational Linguistics In Management Research, Joseph J. Simpson, Richard A. Hunt, David M. Townsend, Judy Rady, Elham Asgari, Mohammad Rady, Daniel J. Beal

International Business and Entrepreneurship Faculty Publications

In recent years, a rapidly growing number of management scholars are using computational linguistics (CL) to analyze vast corpora of naturally occurring organizational language. Yet the rapid adoption of CL methods has outpaced the development of shared standards for linking theoretical constructs, linguistic data, and computational measurement. We synthesize 353 articles published in leading management journals for 2013–2025, identifying four recurring challenges shaping the credibility of CL-based research: misalignment between constructs and textual corpora, unnecessary model complexity, the opacity of large language model workflows, and insufficient transparency in reporting. Building on these patterns, we develop four integrative design principles—construct-language fit, …

Equity-Oriented Mentoring For Occupational Therapy Students In Canada: A Narrative Assessment, Kaarina Valavaara, Tara Pride, Chris Mcwilliam, Jaime Blenus, Stephanie R. Bizzeth, Brenda Beagan

Journal of Occupational Therapy Education

In the health professions, mentoring has emerged as a key strategy for reducing the isolation and exclusion of students from equity-denied groups – including students who identify as Indigenous, racialized, disabled and/or queer. Mentoring often focuses on academic and professional skills, which implies students from these groups are somehow lacking. In contrast, ‘equity-oriented’ mentoring focuses on learning in the context of on-going, everyday isolation, exclusion, discrimination and even hostility. Mentors from the profession, who are also members of the same equity-denied groups, provide role models for thriving in the face of oppression. They may provide psychosocial support while helping students …

Nxumalo, Coalition Of Occupational Therapy Advocates For Diversity Cotad, Alexia Rebne, Janis Yue, Ryan Thomure, Ricardo D. Ramirez

Journal of Occupational Therapy Education

Fieldwork experiences in occupational therapy (OT) and occupational therapy assistant (OTA) education introduce students to novel environments that they must successfully navigate. When examining the experiences of OT and OTA students from minoritized backgrounds, it is critical to understand their fieldwork experiences so that fieldwork educators and partners can create inclusive, supportive environments that promote success for all students. Within this study, a needs assessment was conducted to explore factors that impacted the OT and OTA fieldwork experiences of students from minoritized backgrounds. Using a mixed methods design, a cross-sectional survey was completed by non-faculty OT practitioners (n=48), Academic Fieldwork …

Toward A Critical Occupational Therapy Education: A Discrit-Informed Framework, Robert Niewiadomski, Chia-Yang Chiang

Journal of Occupational Therapy Education

Occupational therapy has long articulated commitments to equity, inclusion, and occupational justice, yet its dominant educational approaches often remain focused on interpersonal competence rather than structural analysis. This conceptual paper argues that contemporary occupational therapy education is insufficiently equipped to prepare practitioners to address the sociopolitical forces shaping occupational participation. Drawing on disability critical race theory (DisCrit), critical pedagogy, intersectionality, and occupational justice scholarship, the authors propose the Critical Occupational Therapy Education (COTE) framework as a structural, justice-oriented reorientation for occupational therapy education. COTE positions racism and ableism as interlocking systems that shape professional norms, knowledge production, and access to …

Validity And Reliability Of The Professional Belonging Scale For Occupational Therapy Students Version 2, Sarah Corcoran Otd, Otr/L, Pooja Patel Drot, Otr/L, Izabela Dubiel Drot, Otr/L, Theresa Rhett-Davis Edd, Otr/L, Nancy Green Ms, Drot, Otr/L, Emily Pasqualetto Drot, Otr/L, Amanda Carter Drot, Otr/L

Journal of Occupational Therapy Education

A strong sense of belonging supports student engagement, motivation, clinical competency, retention, and overall well-being; yet few tools specifically assess this construct in occupational therapy (OT) and occupational therapy assistant (OTA) programs. To address this gap, Corcoran et al. (2025) developed the Professional Belonging Scale for Occupational Therapy Students (PBSOTSv1). The current study aimed to revise the PBSOTSv1 for clarity, inclusivity, and alignment with emerging theoretical frameworks and to evaluate the revised version (PBSOTSv2) for content validity and internal consistency reliability. Revisions involved expert cognitive interviews and Content Validity Index (CVI) ratings, guided by Allen et al.’s framework of belonging, …

Perceived Impacts Of Confucianism On Placement Experiences Of Hong Kong Pre-Registration Occupational Therapy Students In The United Kingdom, Hin Yuet Li, Sarah Louise Mcginley, Rachel Dadswell, Rachel Houweling

Journal of Occupational Therapy Education

This study explored the views of Hong Kong pre-registration occupational therapy (OT) students in the United Kingdom (UK) about how Chinese culture influenced their practice placement experiences. Students from diverse cultural backgrounds may encounter various challenges during OT placements, but little is known about how OT students from Hong Kong—where Confucianism traditionally shapes workplace expectations and the hierarchical teacher‑student relationship—experience placements in the UK. Two online focus groups to collect qualitative data were conducted in November 2022 with four participants who were UK-based OT students from Hong Kong (N=8 in total), two facilitators (OT students from Hong Kong, based in …

The convergence of quantum computing, neuromorphic learning, and distributed cloud infrastructures has occurred very rapidly, and intelligent systems are now providing new opportunities, but the challenge of instability, complexity of orchestration, and noise sensitivity remains in the way of practical integration. The proposed work is based on a hybrid quantum and neuromorphic architecture, which is the integration of event-based neuromorphic adaptation and quantum-assisted global optimization, orchestrated by cloud-HPC. The architecture presents the thermodynamically regularized learning and resourceful task scheduling to the probabilistic search and the continuous local adaptation. Experimental evaluation across financial modeling, medical imaging, and physical system prediction shows …

Contextual Scaffolding And Self-Efficacy: Supporting Computer Skill Development Among Blind Learners In India, Akshay Kolgar Nayak, Yash Prakash, Sampath Jayarathna, Hae-Na Lee, Vikas Ashok

Computer Science Faculty Publications

Inclusive computer literacy education efforts, broadening the participation of blind or visually impaired (BVI) individuals, have gained traction in recent years. Existing literature investigating these efforts primarily draws evidence from affluent Global North contexts, where accessibility resources and legal frameworks are relatively more mature. Little is known about the in-situ teaching and learning challenges faced by trainers and BVI students, respectively, in resource-constrained, multicultural Global South countries like India. To address this knowledge gap, we conducted a four-month contextual inquiry at two computer training centers catering to 94 BVI students in India. We notably observed a rigid, experience-driven training environment …

Finding The Signal In The Noise: An Exploratory Study On Assessing The Effectiveness Of Ai And Accessibility Forums For Blind Users' Support Needs, Satwik Ram Kodandaram, Jiawei Zhou, Xiaojun Bi, Iv Ramakrishnan, Vikas Ashok

Computer Science Faculty Publications

Accessibility forums and, more recently, generative AI tools have become vital resources for blind users seeking solutions to computer-interaction issues and learning about new assistive technologies, screen reader features, tutorials, and software updates. Understanding user experiences with these resources is essential for identifying and addressing persistent support gaps. Towards this, we interviewed 14 blind users who regularly engage with forums and GenAI tools. Findings revealed that forums often overwhelm users with multiple overlapping topics, redundant or irrelevant content, and fragmented responses that must be mentally pieced together, increasing cognitive load. GenAI tools, while offering more direct assistance, introduce new barriers …

Guidelines For Automatic Grading Of Student Essays Using Large Language Models, Diwakar Yalpi, Sruta Keerti Kasula, Ravi Mukkamala

Computer Science Faculty Publications

Automated essay evaluation using large language models (LLMs) has emerged as a promising approach to support scalable and consistent educational assessment. However, the effectiveness of LLM-based grading varies significantly across evaluation dimensions and is highly influenced by prompt design and model selection. In this study, we evaluate five state-of-the-art LLMs across five rubric-based categories: Relevance to Question, Reasoning and Critical Thinking, Evidence and Examples, Organization, and Clarity and Writing Quality. We systematically investigate the impact of three prompting strategies, including rubric-only prompting, exemplar-based prompting (with and without rubric guidance)(Original and Refined prompt designs) incorporating structured instructions. Additionally, a prompt ablation …

Memebuddy: Dialog-Style Audio Representations For Engaging Non-Visual Meme Experiences, Chirag Bhansali, Vikas Ashok, Hae-Na Lee

Computer Science Faculty Publications

Image memes are a pervasive form of online communication, widely used to convey humor, opinions, and cultural references. Prior work has explored making memes accessible to blind users, primarily through auto-generated descriptive captions. While these approaches improve comprehensibility and sometimes incorporate prosodic or emotional cues, they often fail to capture the humor, narrative structure, and contextual nuances that make memes engaging. We present MemeBuddy, a system that models memes as dialog, generating structured, multi-turn audio representations using role-based speakers. MemeBuddy reinterprets a meme as a conversation between two speakers, integrating extracted meme text with contextual knowledge implicitly inferred by a …

Replicatorbench: Benchmarking Llm Agents For Replicability In Social And Behavioral Sciences, Bang Nguyen, Dominik Soós, Qian Ma, Rochana R. Obadage, Zack Ranjan, Sai Koneru, Timothy M. Errington, Shakhlo Nematova, Sarah Rajtmajer, Jian Wu, Meng Jiang

Computer Science Faculty Publications

The literature has witnessed an emerging interest in developing and evaluating AI agents for automated assessment of research claims in scientific papers. Existing benchmarks focus primarily on the computational aspect of this task, testing agents' ability to reproduce or replicate research outcomes when having access to the code and data. This setting, while foundational, (1) fails to capture the inconsistent availability of new data for replication as opposed to reproduction, and (2) lacks ground-truth diversity by focusing exclusively on fully reproducible or replicable papers, thereby failing to evaluate an agent's ability to identify non-replicable research. Furthermore, most benchmarks only evaluate …

Procedural Apartheid? How Racial Harassment Cases And Their Proponents Are Subject To Separate And Unequal Due Process, Suzette M. Malveaux

Scholarly Articles

This article makes three unique contributions. First, it introduces the theoretical framework and coins the term “procedural apartheid.” Simply put, when race is invoked as the basis for misconduct, procedural protection is meted out inequitably, often to the detriment of people of color. This phenomenon is situated in the law’s larger project to preference colorblindness over race-conscious ameliorative efforts. The article invites the reader to broadly consider where separate and unequal proceduralism exists because of the centrality of race. This article deploys the term “apartheid”—not literally, but strategically—to highlight the systemic legal and racial nature of this hierarchical divide.

Second, …

Mental Health First Aid Training In The Community, Vester Agbley Gideon

Doctor of Nursing Practice Projects

Mental health issues impact one in five adults in the United States; however, many individuals lack the requisite knowledge and skills to effectively respond to mental health crises. Mental Health First Aid (MHFA) training empowers individuals to recognize and address mental health concerns, thereby fostering early intervention and support. This review analyses the efficacy of MHFA training, best practices for its implementation, and its influence on mental health outcomes. Empirical evidence indicates that MHFA training enhances mental health literacy, diminishes stigma, and encourages supportive behaviors. Customized approaches for targeted populations, such as youth and older adults, have also shown significant …

Security Governance In Post-Colonial Africa And Implications On Democratic Institutions, Chick Edmond

Political Science & Geography Faculty Publications

This paper will evaluate how security governance contributes to both the development of democracy and the establishment of stable institutions within newly independent post-colonial states in Africa. Security governance is examined here as it relates to the long-term influence of colonial legacy, military presence, and the politicization of the security services. The authors have based their analysis of this issue on qualitative data gathered from Nigeria, Ghana, South Africa, Democratic Republic of Congo, and Kenya. The findings of the research suggest that unless security sectors are subject to civilian oversight and adhere to democratic principles, they tend to serve the …

The Symphony Of Justice: An Intertextual Study Of Social Justice Material Between The Torah And The Psalms, Daniel Gordan

Dissertations

Do passages dealing with social justice in the Torah and the Psalms together comprise an intentionally composed grand symphony, or do they merely form an ad hoc patchwork quilt in which their echoes of similarity are mere coincidences?1 Literary interactions between the Torah and the Prophets of the Hebrew Bible have been a focus of biblical scholarship, but the intertextual connections between the legal corpus of the Torah and poetry in Psalms have not received sufficient attention. Scholars have noticed some thematic similarities, but there are no systematic studies that analyze these interactions to determine whether they involve reuse and, …

The Impact Of Culturally Diverse Student Populations On High School Mathematics Teachers’ Preparations And Practices In Southern Union Conference Of Seventh-Day Adventists, Carla Thrower

Dissertations

The Problem

Across the United States and within faith-based schools recent social and political currents have amplified tensions around culture and belonging in classrooms, particularly for students from racially, ethnically, linguistically, and socioeconomically diverse communities. Evidence indicates that when schooling practices overlook students’ cultural identities or normalize a single cultural frame, students can experience marginalization and reduced access to equitable opportunities to learn (Gay, 2018; Ladson-Billings, 1995; Milner, 2010). In mathematics, a subject often perceived as culture-neutral these dynamics may surface through curriculum choices, participation norms, and expectations that do not meaningfully connect to students’ lived experiences (Aguirre, Mayfield-Ingram, & …

Role-Differentiated Ai Competencies And Curriculum Implications For Health Professions Education: Qualitative Study, Yuyi Park, Yejin Han, Hyeongjo Kim, Solmoe Ahn, Frederick William Kron, Jihyun Lee

Department of Family and Community Medicine Faculty Publications

Background: As AI fundamentally transforms the healthcare landscape, medical education curricula have struggled to keep pace with these technological shifts. While current research has established a foundation for general AI literacy, less attention has been given to the role-specific competencies required for the diverse functions that healthcare professionals perform in an AI-integrated environment. Although existing tiered and domain-based competency models have clarified general AI competency requirements, they offer limited guidance on how such competencies should be differentiated according to the roles healthcare professionals perform in practice.

Objective: This study aimed to explore how AI-driven changes in healthcare shape competency requirements …
