Capitalizing On Crisis: A Statistical Analysis Of Federal Funding And The Surge In White-Collar Criminal Activity During The Covid-19 Pandemic, Lee R. Gibson

Doctoral Dissertations and Projects

The COVID-19 pandemic ushered in a new era that has forever changed how people work, communicate, and socialize. The pandemic also brought one of the most significant influxes of financial assistance to individuals, businesses, educational institutions, and state and local governments that has ever been seen. This massive infusion of cash, which was orchestrated and managed by the federal government, was instituted in a manner that provided quick relief with little ability for oversight, resulting in every assistance program experiencing high rates of fraudulent activity. This project aims to understand if the levels of white-collar crime increase during a disaster, …


Examining The Relationship Of Telehealth Use Between Zoom Fatigue And Psychological Well-Being, And The Moderating Role Of Social Support Seeking And Work-Life Boundaries Among Remote Therapists, Angelia M. Worley Apr 2026

Examining The Relationship Of Telehealth Use Between Zoom Fatigue And Psychological Well-Being, And The Moderating Role Of Social Support Seeking And Work-Life Boundaries Among Remote Therapists, Angelia M. Worley

Doctoral Dissertations and Projects

During the COVID-19 pandemic, mental health therapists rapidly transitioned to telehealth services. In addition, therapists experienced a significant increase in client demand, leading to larger caseloads and longer waitlists. In the post-pandemic context, many therapists have continued to deliver services via telehealth, either fully remote or in a hybrid format. However, there is limited research on the relationship between telehealth intensity and therapist wellness. The purpose of this correlational study was to examine the relationship between telehealth intensity (duration, frequency, and burstiness) and wellness outcomes, specifically, synchronous telehealth fatigue (STF; therapist-related Zoom fatigue) and psychological well-being (PWB). Furthermore, this study …

Exploring Health Policy As A Critical Mechanism Of Expression Of Right-Wing Government Policy, Aleisha Martinez Sandoval Apr 2026

Exploring Health Policy As A Critical Mechanism Of Expression Of Right-Wing Government Policy, Aleisha Martinez Sandoval

Bates College Journal of Political Studies

Global health policy has long been viewed as a “softer” arena of politics, driven by cooperation rather than competition. Unlike economics or defense, nations in this sphere have often set aside ideological differences to improve human well-being. Yet right-wing governments (RWGs) are increasingly redefining this space, transforming it from an international project of solidarity into a strategic platform for advancing core ideological commitments. In this thesis, I examine how healthcare has become a critical site where the foundational tenets of RWGs—hierarchy, tradition, market liberalism, sovereignty, law and order, and populist nativism—are vividly enacted and reinforced. What was once a domain …


Harm Reduction Strategies In Addiction Recovery: Effectiveness, Barriers, And The Role Of Social Stigma, Julia J. Amlin Apr 2026

Harm Reduction Strategies In Addiction Recovery: Effectiveness, Barriers, And The Role Of Social Stigma, Julia J. Amlin

Honors Projects

Substance use disorders (SUDs) present a major global public health crisis. An estimated 46.3 million individuals are affected in the United States, with only a small fraction receiving any form of treatment. While abstinence-based models have historically dominated addiction treatment methods, harm reduction approaches have emerged as evidence-based alternatives that reduce overdose mortality, improve treatment engagement, and decrease the transmission of infectious diseases. Despite strong empirical support harm reduction interventions continue to face significant social, political, and structural resistance. These harm reduction interventions include supervised consumption sites, overdose prevention centers, medication-assisted treatment, naloxone distribution, and drug checking technologies. This resistance …

Analyzing 24-Hour Diet Recalls To Assess Dietary Changes Among Children Who Complete Oral Food Challenges (Ofcs), Hannah Plank, Wan Shen, Heesoon Lee

Honors Projects

Pediatric food allergies are a growing public health concern in America due to their potential association with long-term nutritional impacts and reduced quality of life in those affected. Oral food challenges (OFCs) are considered the gold standard for clinical food allergy diagnosis, but few studies have examined if passing or failing an OFC affects overall diet quality in infants. This clinical observational study examined differences in diet quality, measured by the Healthy Eating Index (HEI), among 39 children aged 0–6 years who participated in OFCs at ProMedica Allergy and Immunology Clinic in Perrysburg, Ohio. Parents and caregivers reported daily dietary …

Building Resilience: The Influence Of The Format On The Effectiveness Of News Literacy Messages, Patrick F. A. Van Erkel, Peter Van Aelst, David N. Hopmann, Claes H. De Vreese, Joren Van Nieuwenborgh

Journal of Media Literacy Education

Although academic interest in news literacy messages (NLM) has grown, many questions about them remain unresolved. First, it remains unclear how the format of the NLM influences its effectiveness. Second, we still know little about their long-term effectiveness. To answer these questions, this study conducted a two-wave experiment in Belgium. We compared NLMs in the format of a text, an infographic, and video. We also manipulated elements in the false news article that participants had to evaluate. Our findings show that NLMs are effective and that the effects remain over a middle-long period of two weeks. Second, we find that …

The likely hosts of L. interrogans were determined using fecal source tracking (FST) assays for human (HF-183), canine (BacCan-UCD), equine (HoF597), and rat mitochondrial DNA NADH dehydrogenase subunit 2 gene (RatMt) markers. In 2024, 91 samples were collected (March: 50; June: 41), and in 2025, 124 samples were collected …


A Phenomenological Study Of The Lived Experiences Of Members Of Alcoholics Anonymous Which Changes Behavior From Addiction To Recovery, Marie Buchanan Wiles Apr 2026

A Phenomenological Study Of The Lived Experiences Of Members Of Alcoholics Anonymous Which Changes Behavior From Addiction To Recovery, Marie Buchanan Wiles

Doctoral Dissertations and Projects

The purpose of this transcendental phenomenological study is to understand the experiences of AA members in rural southern Virginia, leading to behavior changes from addiction to recovery. Exploring these experiences will provide an understanding of how this organization provides recovery capital, reduces rural barriers to addiction treatment, and facilitates a spiritual awakening that supports behavior change. The spiritual awakening is achieved by following the 12-step principles of AA, which results in behavioral changes leading to improved sobriety outcomes. Changes in behavior have been explained by the Social Cognitive Theory, which posits that behavior results from a reciprocal interaction between the …


Cowpox And Counterpublics: A Rhetorical Analysis Of Anti-Covid Vaccine Conspiracy Theories On Social Media, Cole Melton '26 Apr 2026

Cowpox And Counterpublics: A Rhetorical Analysis Of Anti-Covid Vaccine Conspiracy Theories On Social Media, Cole Melton '26

Honor Scholar Theses

In order to better understand why people construct and perpetuate anti-COVID vaccine conspiracy theories, I perform a rhetorical analysis of some conspiracy theories widespread on social media during the height of the COVID vaccination effort. I begin with a literature review, highlighting the history and efficacy of vaccine technology, gathering characteristics and definitions of conspiracy theories, and reviewing the history of the anti-vaccine movement. Ultimately, I argue that anti-COVID vaccine conspiracy theorists understand vaccination as an attack on personal rights by the U.S. government, prompting the conspiracy theorists to establish an ideological institution rival to the U.S. government that would …

Advancing The Understanding Of Palliative Care In Singapore: Knowledge, Attitudes, Receptiveness, And The Moderating Role Of Media Information-Seeking Preferences, Su Lin Yeo, Angel Lee, Raymond Han Lip Ng, May O. Lwin, Yumin Lin

Research Collection Lee Kong Chian School Of Business

Introduction: Despite the growing demand for palliative care, this specialized medical care remains severely underutilized, with almost 50% of countries worldwide lacking access. Given that misperceptions and stigma continue to hinder progress in healthcare policy, this study aims to examine the relationships between palliative care knowledge, attitudes, and receptiveness to better understand how public health communication can enhance awareness and understanding of the topic in Singapore. Applying the adapted knowledge-attitude-practice (KAP) model, it further extends theory by examining the moderating role of media information-seeking between knowledge and receptiveness.Methods: Mixed-mode surveys involving 1,226 participants (926 online and 300 in-person respondents), representing …

Sequencing Dengue Control Policy In Singapore: An Evolutionary Perspective For Policy Design, Ishani Mukherjee, Panchali Guha

Research Collection School of Social Sciences

About half the global population is now at risk of contracting dengue, a mosquito-borne viral infection that can cause severe morbidity and fatalities. Effective dengue control depends on controlling the mosquito vector, but finding the right mix of vector control policies has proved challenging. Using a content analysis of 208 Hansard records from parliamentary proceedings in Singapore, where dengue outbreaks have significantly increased in both frequency and magnitude since the early 1990s, we trace the processual evolution of Singapore’s anti-dengue policy mix from 1960 to 2023 and conclude that the evolution of dengue control policies is consistent with a customized …

Assessing Stakeholders’ Perceptions Of Organizational Effectiveness Through A Multidimensional Theoretical Model: An Interpretive Phenomenological Qualitative Case Study, Andrea M. Paul

School of Public Service Theses & Dissertations

Nonprofit organizations play a fundamental role in meeting community needs when government resources are limited or nonexistent. For decades, scholars and practitioners have recognized the importance of nonprofit-government partnerships for effective public service delivery. This study examines faith-based organizations as a specific type of hybrid nonprofit organization. As social, economic, and environmental challenges intensify, the need for community-based programs led by faith-based organizations also increases. These organizations are working to combat several of society's wicked problems, including but not limited to homelessness, food insecurity, drug addiction, youth and family services, and climate change. Nonprofit sector performance measurement is often recognized …


The Effects Of Covid 19 Job Demands On Public Sector Employees’ Organizational Commitment: The Mediating Roles Of Work Engagement And Job Burnout, And The Moderating Role Of Supervisor Support, Benjamin R. Kaufman Apr 2026

The Effects Of Covid 19 Job Demands On Public Sector Employees’ Organizational Commitment: The Mediating Roles Of Work Engagement And Job Burnout, And The Moderating Role Of Supervisor Support, Benjamin R. Kaufman

Psychology Theses & Dissertations

United States citizens rely on state government employees to provide essential public services. During the COVID-19 pandemic, these employees responded by administering both routine and novel procedures to protect public health, often placing them on the frontlines and at increased risk of contagion. Concurrently, the pandemic-driven economic downturn created budget shortfalls that threatened the job and financial security of the state workforce. Together, these conditions substantially increased job demands for state government employees.

Guided by the Job Demands–Resources (JDR) Model, this study examined how COVID‑19-related job demands influenced state employees’ work engagement, job burnout, and organizational commitment, and whether supervisor …

An Odd Protocol For An Agent-Based Model Of Hepatitis C Virus Transmission In A Homogeneous Syringe-Sharing Network, Seun Ale, Que Thi Nguyet Nguyen Dr., John D. Kelleher Prof., Elizabeth Hunter Dr.

Reports

The model described in this ODD is an agent-based model of hepatitis C virus (HCV) transmission among people who inject drugs (PWID). The model assumes homogeneous mixing among syringe-sharing agents, without any form of heterogeneity in the agents interactions or syringe-sharing attitude. All syringe-sharing PWID are treated as identical in terms of their interaction frequency and syringe-sharing probability. Interactions are generated dynamically using proximity-based sampling at each timestep (one day), allowing agents to form syringe-sharing interactions based on spatial closeness. The number of daily interaction events is fixed at the population level, and each syringe-sharing agent has the same probability …

Using The Misinformation Exposure-Trust Framework For Audience Segmentation: Predicting Covid-19 Vaccine Hesitancy Among U.S., Jing Zeng, Jinxu Li, Nan Yu, Xi Cui, Anli Xiao Ph.D.

Faculty Publications

This study examines whether individuals’ exposure to and trust in COVID-19 vaccine misinformation can be used to segment audiences and explain variations in vaccine hesitancy and health beliefs. Using k-means clustering, a survey of 819 U.S. college students (March–May 2021) identifies four subgroups based on combinations of high or low misinformation exposure and trust: misinformation-shielded (low exposure, low trust), misinformation-vulnerable (low exposure, high trust), misinformation-resistant (high exposure, low trust), and misinformation-accepting (high exposure, high trust). These subgroups differ significantly in political ideology, vaccine hesitancy, and health beliefs. The misinformation-shielded subgroup reports more liberal views, lower hesitancy, and higher perceived efficacy, …
