Avian Conservation And Translocations In The Mariana Archipelago, John V. Bender

Dissertations

Island birds are among the world’s most imperiled vertebrates, and conservation translocations are increasingly used to combat threats, but their success depends on understanding the mechanics of whether and how to conduct translocations effectively. In the Commonwealth of the Northern Mariana Islands, native forest birds persist across a chain of islands where habitat degradation and loss, invasive species, and extreme weather create persistent conservation challenges. For my dissertation, I investigated how avian conservation programs and translocations can be planned, implemented, and improved under biological, logistical, and social uncertainty. For Chapter 1 I analyzed 15 years of avian translocations across seven …

Effect Of Virtual Reality Intervention Of Postoperative Pain In Pediatric Surgical Patients, Tara L. Kempker

Dissertations

Problem: Pediatric surgical procedures are associated with preoperative anxiety. Preoperative anxiety is associated with higher postoperative pain. Multiple studies have found that decreasing preoperative anxiety using Virtual Reality (VR) Intervention also decreases postoperative pain scores and use of rescue analgesics in postoperative care units (PACU). However, there is no standardized protocol for use of VR interventions and in our institution, VR was not utilized at all.

Methods: This quality improvement (QI) initiative utilized a quasi-experimental design and convenience sampling. Quantitative data was collected during visits for scheduled operative visits for pediatric surgical patients ages seven to 18 years …

Sleep Disturbances Affect Sleep Quality Of Hospitalized Adults, Tonjia Hardesty

Dissertations

Abstract

Background: Sleep disturbances affect the quality of sleep hospitalized adults experience, possibly extending patient recovery time. Treatment of insomnia frequently includes pharmacological interventions exposing patients to potential side effects, leading to negative patient outcomes.  The purpose of this project was to determine if a sleep hygiene toolkit including eye masks, earplugs, advocacy cards, and removal of nicotine patches at bedtime would improve patient sleep quality without use of pharmacological interventions.

Methods: A descriptive observational design was used in this quality improvement (QI) project. A convenience sample of 37 (N =37) participants over the age of 18 years and …

Enhancing Well-Being: Implementing Weekly Social Interventions For Older Adults In Independent Living, Rosa Huang

Dissertations

Loneliness and social isolation significantly impact the physical and mental well-being of older adults. This quality improvement project implemented an eight-week social intervention designed to reduce loneliness and enhance well-being through weekly sessions incorporating mindfulness exercises, gratitude journaling, and structured socialization activities. The intervention was delivered by nursing students to a sample of residents in a Midwestern independent living community. While most standardized measures of loneliness and mood did not show statistically significant changes, the project resulted in a statistically significant increase in social network engagement as measured by the Lubben Social Network Scale-6 (LSNS-6). The findings suggest that group-based …

Defining Contractile And Age-Specific Remodeling In Atrial Fibrillation, Hannah Cizauskas

Dissertations

Atrial fibrillation (AFib) is the most common cardiac arrythmia worldwide and is characterized by hallmarks including electrical, fibrotic, and hemodynamic remodeling, each of which can cause or be caused by alterations in the contractile apparatus. However, there is little known about contractile remodeling in AFib. While our current understanding of AFib lacks contractile remodeling, it also largely ignores the contribution of aging-induced remodeling. Aging is the strongest risk factor for AFib development, with most patients diagnosed with AFib over the age of 70, and aging also involves the three molecular hallmarks of AFib, which could explain increased susceptibility of AFib …

School safety practices can influence students' perceptions of safety, emotional well-being, and engagement in the educational environment; however, limited research has examined whether trauma-informed safety drill practices are associated with measurable educational outcomes. The purpose of this quantitative, non-experimental, correlational study was to examine the relationship between trauma-informed safety drill practices and school-level chronic absenteeism in Maine middle and high schools. Guided by trauma-informed care, adolescent neurodevelopment, and Protection Motivation Theory, the study investigated whether higher levels of trauma-informed implementation of safety drills, as measured by the Trauma-Informed Safety Drill Practices Index (TISDPI), were associated with lower rates of chronic …

Exploring Primary Care Providers’ Compassionate Care And Their Evidence-Based Practice With Death, Grief, And Loss: Patient Experience And Perspective, Kathryn Krzykala

Dissertations

Research on primary care providers’ (PCPs) education regarding Death, Grief, and Loss (DGL) remains limited. Specifically, data is lacking regarding patients' perceptions and opinions on what they need and expect from their PCPs regarding grief and loss. This exploratory mixed-method study comprised 146 participants who had experienced death and non-death loss. It examined participants' perceptions of 1) PCP compassion, 2) PCP utilization of evidence-based grief and loss practices, 3) their own level of comfort discussing DGL with their PCPs during medical visits, and 4) their personal grief and loss experiences. The findings revealed that PCPs' grief-informed evidence-based treatment, as reflected …

Monitoring And Short-Term Forecasting Of Atmospheric Air Pollutants Using Deep Neural Networks, Prasanjit Dey

Dissertations

Accurate forecasting of near-surface atmospheric air pollutants such as PM2.5, NO2, SO2, CO, and O3 remains a critical scientific and societal challenge. This difficulty arises from several factors, including nonlinear pollutant dynamics, sparse ground monitoring net works, heterogeneous satellite observations, and strong cross-pollutant interdependencies. Substantial advances have been achieved in temporal deep learning, probabilistic modeling, satellite-based estimation, physics-informed methods, and foundation models. However, these paradigms have largely evolved in isolation. As a result, existing systems are often station-dependent or pollutant-specific and optimized for a single forecasting task. This limits their robustness and generalizability across regions and heterogeneous data regimes.

This qualitative study examined how college athletes, 18 years and older, experience and interpret internalizing behaviors and externalizing behaviors within contact and non-contact sports, and how those experiences are shaped by gender, racial/ethnic background, and socioeconomic status. The study addressed a gap in the literature by centering athletes’ own perspectives on how emotions, coping, identity, and performance intersect within collegiate sport contexts. A purposive sample of 12 athletes completed a demographic questionnaire and participated in semi-structured interviews conducted in person between December 2025 and February 2026. Interview transcripts were deidentified and analyzed using reflexive thematic analysis following Braun and Clarke’s …

Strengthening The Shield: Exploring Post-Traumatic Growth In Law Enforcement, Aaleiyah C. Spaulding

Dissertations

Law enforcement officers are routinely exposed to traumatic incidents that can lead to psychological distress, including posttraumatic stress disorder (PTSD). However, emerging literature highlights the potential for posttraumatic growth (PTG), a positive psychological change following adversity. This study examined the prevalence and predictors of PTG in a sample of 33 police officers from a Midwestern department. Using validated self-report measures, the study assessed the role of trauma exposure, cognitive restructuring of core beliefs, and perceived organizational culture, particularly supervisor support. Results indicated that both internal (core belief reflection) and external (supervisory support) factors significantly predicted PTG. Additionally, involvement in a …

Investigating The Role Of Cellular Senescence On Vestibular Dysfunction In Repetitive Mild Traumatic Brain Injury, Michael Volyanyuk

Dissertations

Vestibular dysfunction is a prevalent and persistent consequence of mild traumatic brain injury (mTBI). Clinical reports reveal that women experience vestibular deficits more frequently than men following mTBI. Despite the high prevalence and debilitating nature of vestibular symptoms, preclinical literature evaluating mTBI-associated vestibular impairments is limited. Emerging evidence demonstrates that cellular senescence is involved in the pathological molecular sequela of mTBI. It has been shown that senescence contributes to cognitive deficits following repetitive mTBI (rmTBI); however, its role in rmTBI-associated vestibular dysfunction remains unexplored. This body of work investigated the role of cellular senescence on rmTBI-induced vestibular dysfunction in both …

An Untapped Resource: Exploring The Role Of Spirituality In The Psychological Healing Of African Asylum-Seekers From A Counselor’S Perspective, Brittany A. Duncan

Dissertations

This qualitative study explored how counselors perceive and integrate spirituality into the psychological healing of African asylum-seekers, a population facing compounded cultural, legal, and existential challenges. Using interpretative phenomenological analysis, the study examined the lived experiences of eight counselors working with this population. Findings revealed that counselors’ personal sense of religion influenced their comfort and approach in broaching spiritual topics, with both positive (e.g., spirituality as a source of support and community) and negative (e.g., religion as a source of suffering) associations shaping clinical engagement. Many participants reported limited access to trainings geared towards increasing their cultural competence related to …

Don't Force Me To Explain: Rethinking Access Outside Of Compulsory Transparency, Rhea Ienni

Dissertations

My dissertation is concerned with better understanding the barriers disabled people encounter while attempting to procure access both at the institutional level, and in their everyday lives. Within disability and accessibility literature, there are many discourses on what disability is and what access means. However, there are few people who explore the harmful consequences of disabled people being forced to “prove” they are disabled to an ableist world to get their basic needs met, and my dissertation intervenes in this gap. Within current US policy, if a disabled person requires access support at the institutional level, they must provide medical …

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

Dissertations

Although gratitude has been widely studied in social science, existing scholarship has largely relied on Western worldviews and quantitative research frameworks, limiting understanding of lived gratitude experiences within diverse spiritual and cultural contexts, including Eastern spiritual traditions. In Won Buddhism, originating in South Korea, gratitude holds a central place in spiritual life and is understood as an essential practice. This qualitative study explores the views of Won Buddhist older adult practitioners regarding their experiences, benefits, and challenges of engaging in spiritually grounded gratitude practice. Semi-structured interviews were conducted with 23 practitioners aged 65 and older from English-speaking Won Buddhist communities. …

Being Desi At School: Exploring The Racialized School Experiences Of South Asian American Youth, Prabha Kaundinya

Dissertations

Schools in America have been central areas for racialization, and as an immigrant, racial-ethnic minority population, South Asian American (SAA) students have been subjected to a variety of racialization processes (S. J. Lee et al., 2017; Rice, 2017, 2019; Subedi, 2013). However, what is known about SAA educational experiences is often based on celebratory stereotypes that proclaim their uniform success while neglecting attention towards the diversity of their needs (including academic, social-emotional, or mental health needs; Saran, 2015; Ngo & Lee, 2007; P. Patel & Patel, 2017; Pedraza & Guillaume, 2023; N. Sharma et al., 2020). This dissertation uses a …

Making Sense Of The Barrio: Place-Based Appraisal And Coping Among Latine Residents In Chicago, Juanita Vivas Bastidas

Dissertations

Residents of Chicago’s Latine barrios often describe their neighborhoods as places of familiarity and safety—sites defined by both personal independence and collective solidarity, where daily life is marked by a sense of belonging and mutual support. Yet, residents also contend daily with overlapping social and environmental stressors. While urban, medical, and environmental sociologists have each shown that place matters, their findings remain siloed and rarely integrated to illuminate the everyday realities of Latine neighborhoods. As a result, we lack a systematic analysis of how people living in Chicago’s Latine barrios make sense of and cope with multiple, simultaneous stressors. I …

Responsive Rigor And Strategic Care: Faculty Praxis For Holistic Student Success In The Community College, Jennifer Elizabeth Kelley

Dissertations

This qualitative study examines how community college faculty conceptualize, communicate, and enact academic rigor and care in their teaching practice. While post-pandemic debates have positioned rigor and care as opposing forces—evident in the "Rigor Wars" that framed care as performative laxity and rigor as gatekeeping—community college faculty successfully integrate these practices to support holistic student success. This research addresses critical gaps in higher education scholarship, which has studied rigor and care separately, focused primarily on four-year institutions, and overlooked faculty perspectives on how integration occurs in practice. Drawing on a single-case study of 38 faculty members at a large Midwestern …

The Year Of Birth Age Grouping Policy: Its Impact On Participation In Us Youth Soccer, Murray James Findlay

Dissertations

In 2016, the United States Soccer Federation (USSF) implemented a nationwide year-of-birth (YOB) age grouping policy that aligned youth soccer teams with calendar years (January 1st –December 31st), replacing the traditional schoolyear (August 1st –July 31st) grouping system. This dissertation investigates the impact of that policy on youth soccer participation in the United States, addressing a critical gap in empirical research linking national policy interventions to participation outcomes. Framed through the Fun Integration Theory (FIT) (Visek et al., 2015), which conceptualizes youth sport engagement as driven by social and intrinsic enjoyment factors, the study examines whether the YOB policy caused …

Uncovering Dkk1 As A Therapeutically Relevant Target In Aggressive Er+ Breast Cancer Using A Novel Antiestrogen, Kristen Young

Dissertations

Over 70 percent of breast cancers are estrogen receptor-positive (ERα+), meaning that the hormone estrogen drives tumor growth. Although first-line targeted therapies that directly block ERα from hormone-dependent pathologies are initially effective, almost half of patients ultimately progress. These patients show high mutational rates to the ESR1 gene that encodes for ERα. A hotspot missense tyrosine to serine mutation at position 537 (Y537S) initiates hormone-independent, allele-specific transcriptional programs that increase metastasis. While next-generation ERα-targeted therapies show promise, benefits are often limited compared to standard-of-care. Understanding the mechanisms of action used by the Y537S ESR1 breast cancer cells to evade therapeutic …

Enhancing Postsecondary Outcomes For Students With Emotional And Behavioral Disorders: A Design-Based Mixed Methods Approach To Transition Planning, Kate M. Schrum

Dissertations

Students with emotional and behavioral disorders (EBD) experienced significantly lower postsecondary outcomes when compared to same-aged peers. These outcomes included lower graduation rates, higher unemployment rates, and difficulty establishing independent living arrangements (Wagner & Newman, 2015). Following a human-centered, design-based approach, the scholar-practitioner found a lack of consistent and meaningful transition support specifically designed for students with EBD. Working with a stakeholder team of educational professionals directly involved in supporting transition for students with EBD at an alternative special education program, the scholar-practitioner developed a "Transition Toolkit". The toolkit contained scaffolded grade-level checklists (for grades 6–12) with self-advocacy and goal-setting …

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 …

Well-Being, Resilience, And Trauma During Migration: A Mixed Methods Study Of Venezuelan Migrants In Transit, Margaret S. Port

Dissertations

A substantial body of research has examined the psychological impact of experiences preceding and following migration, yet comparatively little attention has been given to the psychological toll of the migration journey itself. Moreover, due to the relative novelty of the Venezuelan migrant crisis and the community’s arrival in the United States, the psychological impact of Venezuelan migrants’ unique migration experience has been underexamined. This study utilized an explanatory sequential mixed methods design to investigate the relationships between well-being, resilience, and trauma among Venezuelan migrants in Chicago, Illinois, while also exploring their lived experiences of the migration journey. Study participants (n …

Understanding And Enhancing Suicide Prevention Strategies In The Military: The Roles Of Culture, Leadership, And Command Climate, Kelly Johanna Pires

Dissertations

Military service members are shaped and molded to fit a military culture that emphasizes mission readiness and continuous preparedness. Countless hours are spent training for various situations that can arise. Many trainings are geared toward worst-case scenarios that can cause an increase in stressors and traumatic events. They are expected to demonstrate resilience and overcome adversity to remain mission-ready. This expectation to be mission-ready creates the space for mental health difficulties as well as stigma and avoidance of help-seeking behaviors. In many cases, the desire to stay mission-ready creates a barrier for conversations around mental health. The military emphasizes qualities …
