Emergency Medical Services Mental Health: Causes Of Providers Leaving The Industry, Brian C. Selke

Graduate Theses and Dissertations (2019 - present)

Employee resilience and mental health have become critical concerns in Emergency Medical Services (EMS) as workforce shortages increasingly threaten staffing stability and patient care. National Registry of Emergency Medical Technicians (NREMT) data indicates that more than 30% of eligible EMS providers did not recertify between 2020 and 2023, raising concerns about workforce sustainability. This study examines EMS providers’ intentions to leave the profession and identifies workplace factors associated with turnover. A statewide survey of more than 1,200 licensed EMS providers in Alabama was analyzed using regression techniques to evaluate the relationship between workplace conditions and turnover intentions. Results demonstrate that …

"I Can See Where This Is Taking Me": Medical Students' Perceptions Of Humanities Courses At Aga Khan University, Kenya, Catherine Gathu, Marthaclaire Zammit, Urvi Saboo, Robert Opoka

Family Medicine, East Africa

Background Humanities courses in medical training are increasingly recognized as essential for developing empathetic, reflective and socially responsive physicians. Although well-established globally, their integration into medical education in African contexts remains limited. In Kenya, humanities are often peripheral within curricula dominated by biomedical sciences and clinical medicine. Aga Khan University (AKU), Nairobi, has introduced a novel medical curriculum that embeds seven core humanities courses as central components of the initial phase of its MBChB program. This study explored students’ perceptions and lived experiences of these humanities courses.

Methods A retrospective descriptive study using an embedded mixed-methods design was conducted among …

Effects Of Beverage Color During Mouth Rinsing On Measures Of Muscular Endurance, Muscular Strength, And Exercise Perceptions During Isometric Handgrip Testing, Sydney Andrews

Exercise Science Theses & Dissertations

Previous research has shown that color can influence psychological responses, physiological responses, and exercise performance. These effects have been previously attributed to learned associations or expectations which may influence exercise-related outcomes. This study aimed to investigate whether beverage color influences muscular performance during intermittent isometric handgrip exercise. This randomized, single-blind, deceptive crossover study consisted of 34 physically active adults (21.9±3.1 years) who completed a handgrip endurance test under three conditions: red beverage rinse, clear beverage rinse, and no-rinse. Participants were informed that the study would examine the effects of mouth rinsing two commercially available carbohydrate containing sport drinks on muscular …

Menopausal Symptoms, Psychosocial Factors, And Physical Activity Among Physically Active Midlife Females, Ella Onsoriasl

Exercise Science Theses & Dissertations

Menopausal symptoms are common during midlife and may be associated with females' physical activity (PA) participation, yet how these symptoms relate to PA levels, perceived confidence and enjoyment, and psychosocial resources such as social support (SS), exercise identity, and quality of life (QOL) remains unclear. The purpose of this study was to examine how menopausal symptom severity relates to PA levels, perceived confidence and enjoyment during PA, and psychosocial factors, including SS, exercise identity, and QOL. This cross-sectional study surveyed 151 midlife females aged 40 to 60 who reported engaging in intentional PA at least once per week. Participants completed …

Navigating The Dark Side: Emotional Labor's Impact On Hr Professionals' Wellness, Esmeralda Amelia Rendón

Electronic Theses and Dissertations

This qualitative descriptive study was designed to document and describe how female-identifying human resource (HR) generalist practitioners serving as sole or primary employee relations practitioners in small- to medium-sized organizations across the United States experience and manage emotional labor in their roles, cope with its demands, and how these experiences impact their wellness and perceptions of organizational support. Despite the centrality of emotional labor (EL) in human resource professionals’ (HRPs) roles, little was known about how HRPs in these underresourced environments cope with these demands. Data were collected through semistructured virtual interviews with eight participants and analyzed using Braun and …

Cultural Values, Norms, And Mental Health Service Utilization Among Young Adult Guyanese Immigrants, Rhonis Alfred

Walden Dissertations and Doctoral Studies

Young adult Guyanese immigrants living in the United States often face cultural, familial, and social challenges that influence their perceptions of mental health and willingness to seek professional support. Despite growing attention to immigrant mental health, limited research has explored the experiences of this population. This qualitative study aimed to improve understanding of how cultural values, family dynamics, and acculturation stress influence mental health perceptions and help-seeking behaviors. The theoretical framework underpinning this study was acculturation theory. The research explored how participants navigated cultural identity, family expectations, and adaptation to life in the United States. A purposive sampling strategy was …

Phenomenological Exploration Of The Military Veterans' Experiences Transitioning Into Civilian Workplace In Central Florida, James Wesley Shelton

Walden Dissertations and Doctoral Studies

Military veterans transitioning from military service to civilian employment frequently encounter challenges related to workforce integration, translating military-acquired skills, adapting to civilian workplace cultures, and employer perceptions of their qualifications. Organizational leaders need to understand these challenges as a key indicator of the factors that influence successful workforce integration, organizational commitment, and employee retention. Grounded in person-environment fit theory, the purpose of this qualitative study using an interpretative phenomenological analysis (IPA) approach was to explore the lived experiences of military veterans and how they make meaning of their transition to the civilian workplace. The participants comprised seven U.S. military veterans …

From Personal To Personalized Goals: How Goal Nudges Improve Production, Joaquín Gómez-Miñambres, Brice Corgnet, Roberto Hernán González

ESI Working Papers

We study how workers’ non-binding self-set goals affect their production and whether goal nudges (ability-calibrated goal hints) make goal setting more effective. In a real-effort task, participants first complete an ability pretest and are then assigned to one of three treatments: a no-goal baseline, a personal goal treatment with no external hint, or a personalized goal nudge that participants may accept or modify. We document a positive link between goals and production. However, merely asking workers to set goals is ineffective: when left unguided, workers anchor on conservative goals well below those induced by goal nudges, leading to underperformance. In …

Why They Stay: Career Development, Personal Growth, And The Retention Of Higher Education General Staff, Ursula Brady

All Dissertations

Higher education general staff (HEGS) are critical to the operational continuity and institutional success of U.S. colleges and universities, yet their retention remains a persistent challenge. While faculty development has received sustained attention, HEGS have historically lacked equivalent access to career advancement and personal growth opportunities. This study examined how perceived access to career development and personal growth opportunities was associated with job satisfaction and turnover intention among HEGS and tested whether job satisfaction mediated these relationships. Grounded in Self-Determination Theory and Herzberg's Two-Factor Theory, this study hypothesized that career development and personal growth would predict turnover intention both directly …

Shared Identity, Shared Trust: How Cultural Sensitivity Signaling And Advisor Race Shape Minority Investors' Trust And Investment Intentions, Kathy J. Kuria

All Dissertations

Persistent racial disparities in stock market participation constrain wealth accumulation among African American and Latino households. This study examined how two forms of representation, a firm’s cultural-sensitivity disclosure (an organizational signal) and the advisor’s racial identity, shape trust and investment intentions among these groups. Drawing on social identity theory, signaling theory, and the impression-formation/stereotype-reconciliation literature, this study hypothesized that disclosure and a minority advisor independently increase trust, that the cues would be complementary, and that trust would mediate their impact on investment intentions. A 2 × 2 between-subjects experiment with African American and Latino adults tested predictions using ANOVA, ANCOVA, …

Beyond Execution: Managerial Attributes For Successful Experiential Marketing, Joann Imosi Emale

All Dissertations

This study examined the relationship between what consumers value in experiential marketing events and the managerial competencies organizations seek when hiring experiential marketing roles. As brands increasingly compete on emotional and sensory engagement, the experiential marketing manager has become central to execution, yet the role remains loosely defined, and the skills it demands are rarely tied to what audiences respond to. This research addressed that gap by asking which event attributes consumers prized most, which respondent characteristics shaped those preferences, and what competencies employers asked for when they hired the managers who built these experiences.

Survey data were collected from …

Parametric Assessment Of Nicotine Vapor Self-Administration In Rats, Tiffany Alexandra Gonzalez-Gutierrez

Open Access Theses & Dissertations

The increasing prevalence of electronic cigarette (e-cigarette) use among adolescents highlights the need to identify factors that promote nicotine vapor use in populations most susceptible to its long-term consequences. This requires translationally relevant animal models of nicotine vapor self-administration (VSA). Accordingly, the goal of this dissertation was to evaluate 2 key factors hypothesized to influence nicotine VSA in rats, including age and e-liquid vehicle composition. Given recent mandates on studying sex as a biological variable, the present work included both female and male rats. Aim 1 compared VSA behavior during adolescence (adolescent-onset) or adulthood (adult-onset) in groups that received vapor …

Food Insecurity And Parent Engagement In Pediatric Therapy: A Comparative Study Of Feeding, Speech-Language, And Combined Services, Kendra Kendra Rosales

Open Access Theses & Dissertations

Pediatric feeding disorders and food insecurity represent two compounding challenges for families navigating pediatric therapy services, yet their intersection has received little empirical attention. This study examined food insecurity rates across three pediatric therapy groups and explored the relationship between food insecurity and parent engagement in therapy. A cross-sectional online survey was administered to 175 caregivers of children actively receiving feeding therapy only (n = 34), speech-language therapy only (n = 93), or combined feeding and speech-language therapy (n = 48). Food insecurity was assessed using the USDA Household Food Security Survey Module: Six-Item Short Form, and parent engagement was …

Domain Adaptation Of Facial Age Estimation For Law Enforcement Mugshot Repositories, Jorge Alejandro Pacheco Roque

Open Access Theses & Dissertations

Facial age estimation supports law enforcement via image-based, age-filtered queries, age-progressive re-identification, and bulk record labeling, where prediction accuracy determines if the resulting decisions can be trusted. State-of-the-art models excel on web imagery but incur higher error on mugshots due to domain shift between the professionally lit, filtered, and posed web photographs used during pre-training and the uniform backgrounds, uncooperative expressions, and decades of evolving capture technology found in mugshot collections. We address this gap by adapting SwinFace - a state-of-the-art multi-task Swin Transformer with public code and pretrained weights, trained on color face imagery for face recognition, facial expression …

"Fenomeno Frontera:" Family Language Policy As Lived Experience At The U.S.-Mexico Borderlands, Alejandra Sanmiguel-Lopez

Open Access Theses & Dissertations

Family language policy (FLP) research expands the understanding of how families' language ideologies, language management, and language practices shape children's bilingual development. However, limited research has examined these processes among transfronterizo families living along the U.S.-México border. This qualitative narrative inquiry explores how transfronterizo families describe and negotiate their family language policies and how these policies relate to their experiences in the borderland, including their relationships with schools. Guided by family language policy and borderlands theory, this dissertation employs Seidman's (2006) three-interview series with five transfronterizo mothers raising children enrolled in dual language programs in the El Paso, Texas, region. …

Essays On Firm-Level Political Risk, Addback Statutes, And Corporate Decisions, Obed Nana Buadi

Open Access Theses & Dissertations

This dissertation comprises three chapters examining how political risk and tax enforcement shape corporate investment decisions and firm value. The first essay investigates how firm-level political risk affects investment efficiency among U.S. firms. Using 40,215 firm-year observations spanning 2002-2022 and exploiting the Hassan et al. (2019) political risk index as a firm-specific measure, we find that political risk reduces investment efficiency exclusively through underinvestment - a one-standard-deviation increase corresponds to approximately $5.7 million in foregone annual investment for a median firm. Mediation analysis confirms that precautionary cash hoarding accounts for 31.8% of the effect, establishing uncertainty - rather than capital …

Prevalence Of Type 2 Diabetes Risk Factors Among Landscaping Workers In El Paso, Texas, Valeria Fontes

Open Access Theses & Dissertations

Type 2 diabetes mellitus (T2DM) is a significant public health challenge worldwide, yet little is known about the prevalence of diabetes risk factors among landscaping workers, an understudied occupational group. The purpose of this pilot study was to estimate the prevalence of type 2 diabetes risk factors among landscaping workers in El Paso, Texas. A descriptive cross-sectional study was conducted using a convenience sample of 20 landscaping workers. Participants completed a structured questionnaire and underwent anthropometric measurements, blood pressure assessment, point-of-care lipid and glucose testing, and vitamin D screening. Sixteen type 2 diabetes risk factors were assessed across seven domains: …

An Exploration Of The Psychological Impacts Of Code-Switching, Cristina Culler

Electronic Theses and Dissertations

This dissertation is an interpretative phenomenological analysis of the lived experiences of four Black American adults who have frequently engaged in code-switching. Historically, code-switching has been perceived as a necessary skill that helps marginalized folx adopt the norms and practices of the dominant culture. As a result, code-switching has become a routine practice specifically for Black Americans who often occupy white spaces. Since code-switching has been perceived as a skill, the oppressive origins of code-switching often go unnoticed. Therefore, this dissertation examines code-switching through a critical lens that deems this practice a product of racist ideologies that prioritize whiteness. Through …

Guest Editor’S Introduction: Liah Greenfeld And The Future Of Comparative Civilizational Studies, Monika Monika, Guest Editor

Comparative Civilizations Review

Every scholarly life leaves behind unfinished questions. Professor Liah Greenfeld was acutely aware of this. Throughout a career spanning more than four decades, her research never settled into the repetition of established arguments. Each major work emerged from the unresolved problems of the previous one, enlarging both the scope of its inquiry and the range of disciplines with which it engaged. Nationalism led her to questions of modernity (Greenfeld, 1992) and the foundations of economic development (Greenfeld, 2001). The growth of the modern economy and the emerging new forces of globalization, in turn, raised broader questions about the self and …

Constructing Executive Presence Within The Double Bind: Women’S Experiences Of Leadership Communication, Sydney Anne Shumaker

Communication Studies

Women in executive leadership often face a gendered double bind, expected to be warm and approachable, while also appearing competent and confident. This qualitative study examines how women executives develop executive presence and navigate these workplace expectations. Drawing on Warmth-Competence Theory and Impression Management Theory, the study explores how women leaders adapt their communication, manage self-presentation, and balance perceptions of warmth and competence in professional settings. This study involved conducting semi-structured interviews with four women in corporate executive-level roles. Thematic analysis of participant responses revealed five key themes: adaptive communication, varied experiences with gendered workplace expectations, the importance of credibility …

Using Assessments Intentionally With Consideration For English Language Learners, Elizabeth Ropp

Masters Projects

Assessment systems in the United States are failing English Language Learners (ELLs), and it has become apparent that action must be taken to try and right this injustice. There is a wide achievement gap between native English speakers and non-native English speakers when it comes to performance on state, local, and classroom assessments. Unfortunately, many teachers report that they do not feel adequately prepared to support ELLs both on classroom assessments and on mandatory state or local tests. With an ever-growing increase in ELL enrollment in American schools, it is imperative that teachers are given tools to help them better …

Secure And Compassionate Dementia Care: Non-Intrusive Remote Monitoring Of Falls, Wandering, And Agitation, Awan-Ur- Rahman

Master's Theses

Alzheimer’s disease and related dementias (ADRD) present significant safety challenges, as affected individuals may experience falls, wandering, agitation, and a progressive decline in independence. Although continuous monitoring can enable timely intervention, many existing systems rely on cameras or wearable devices, which may introduce concerns related to privacy, comfort, and sustained use. This thesis explores privacy-preserving and non-intrusive remote monitoring through two complementary studies. The first study presents an ambient Wi-Fi channel state information framework for recognizing agitation and eight daily activities. The proposed approach translates behavioral and physiological markers commonly captured by wearable sensors into the Wi-Fi sensing domain. The …

Secondary Biology Teachers’ Understandings Of Growth Mindset, Kathryn Chapman

Dissertations

This case study investigates how high school biology teachers understand and apply growth mindset principles in their daily instruction. Using surveys, semi‑structured interviews, and focus groups, the study examines how biology teachers interpret mindset, how they attempt to enact it, and how curriculum demands shape their efforts. Findings show that teachers’ beliefs about intelligence strongly influence their feedback, expectations, and instructional decisions. Teachers described biology as a subject in which struggle is highly visible, emotionally charged, and often tied to students’ prior knowledge, making mindset work both necessary and challenging. Results also indicate that students’ mindsets are shaped by broader …

Gaming The Marketplace: Consumer Opportunism And Beliefs About Societal Hierarchy, Shilpa Madan, Aparna Labroo, Constantine S. Katsikeas

Research Collection Lee Kong Chian School Of Business

Consumers often behave opportunistically, taking more than what fair marketplace exchange warrants (e.g., taking excess samples, returning used items). While each individual transgression may be minor, cumulatively they can undermine firm profitability. Thus, addressing consumer opportunism is an important managerial concern. We identify a novel antecedent of consumer opportunism: consumers’ acceptance of societal hierarchy (i.e., power distance belief [PDB]), including firms’ higher position in it than consumers. Nine studies (plus two supplementary studies) employing archival, correlational, and experimental data provide converging evidence that, in marketplace interactions, this belief evokes a need to feel clever (i.e., to feel smart and knowledgeable …

Exploring Public Perceptions Of Genetic Risk In Substance Use Disorders, Brooke A. Goodenow

All Dissertations

This dissertation examines genetic risk perception, with specific emphasis on substance use disorders (SUDs), through a collection of three manuscripts. The dissertation examines genetic risk perception for hereditary diseases in existing literature, describes a methodological framework for capturing genetic risk perception across social media discourse, and identifies themes and emotional tone associated with genetic risk perception for SUDs across two major social media platforms (X and Reddit).

Combined, these three manuscripts expand and support previous findings about genetic risk perception and its role in shaping health beliefs and associated behaviors. The dissertation findings reveal numerous similarities in genetic risk perception …

Student Motivation In Social Studies Classes At The Public Museum High School: A Dissertation, Benjamin Kruid

All Dissertations

Students tend to behave differently in different classroom settings. Many factors contribute to the change in behavior, including motivation. Research suggests a tendency for student motivation to decrease as students move from elementary to middle to high school. However, motivation in students is not uniform and is dependent on factors like the subject, and time of day, for example. This dissertation examines student motivation in social studies classes at a public high school in Michigan using Situated Expectancy-Value Theory (SEVT) as a framework for understanding motivation, and student impulsiveness as understood through the lens of Delay Discounting (DD). This research …

When Your Neighbours Are A Reminder Of Your Ageing, Cynthia Tan, Yi Wen (Chen Yiwen) Tan

ROSA Journal Articles and Publications

In a commentary, Cynthia Tan, a retired senior corporate leader, and Tan Yi Wen, a Senior Research Fellow at SMU’s Centre for Research on Successful Ageing (ROSA), questioned whether the low demand for community care apartments is because seniors do not want only other seniors for company. They noted that most older people do not spend their days dwelling on ageing until everyone around them reminds them that they are growing old. They added that prolonged exposure to such an environment may carry subtle emotional and psychological consequences. Citing a national survey by ROSA, the writers mentioned that eight in …
