Disability And Self-Identity: Examining Their Relationship And Impact On First-Year Students’ College Transition, Caroline A. Mcpartlin

Electronic Theses & Dissertations (2024 - present)

As students with disabilities enroll in college at increasing rates, higher education institutions (HEIs) are challenged to consider students with disabilities’ unique needs. Student development theory informs higher education policy and practice but lacks disability perspectives. As such, this study was designed to narrow gaps in disability literature and supplement student development theory with a needed disability perspective. Through an examination of how participants categorized their self-identities and identities as college students, this study investigated students with disabilities’ identity development and its impact on their college transition.

Utilizing qualitative interviews, 12 students with disabilities (SWDs) were prompted to share their …

Stem Cell-Derived Developmental Models For Translational Evaluation Of Disease And Therapy, Maria B. Paredes-Espinosa

Electronic Theses & Dissertations (2024 - present)

Human development as well as congenital and adult diseases emerge from coordinated interactions among multiple cell types, regulatory programs, and tissue compartments that remain largely unresolved. Conventional simple lineage-restricted in vitro systems poorly capture this complexity. My dissertation uses human stem cell-derived developmental models to study human cardiac morphogenesis and heart diseases and application of a networked neuron platform to explore senescence-associated neurodegeneration impact on Alzheimer’s neurons.

Elongating multi-lineage organized cardiac (EMLOC) gastruloids are a synthetic embryology model that co-generates contractile cardiomyocyte populations alongside mesenchymal, endothelial, epicardial-like, neural crest-associated, and neuronal cells within a shared in vitro developmental environment. Single-cell …

Exploring The Impact Of Mindful Social Media Literacy Instruction On Self-Regulated Smartphone Use, Catherine Coons

Electronic Theses & Dissertations (2024 - present)

Smartphone and social media addiction, and increasingly high rates of anxiety and other mental health challenges, afflict contemporary undergraduate students more than previous generations of college students. The mental health challenges faced by students directly affect their academic potential, influencing their ability to concentrate, maintain confidence, get adequate sleep, and sustain overall well-being. Despite the increasing prevalence of these issues, universities often lack sufficient resources, services, and trained staff to support this growing student population adequately.

This study examines the impact of mindfulness-based social media literacy instruction on curbing problematic social media use in college students. While extensive research has …

Understanding The Intergenerational Transmission Of Risk And Resilience In Black Birthing Parent-Infant Dyads: Physiological Coregulation & Cultural-Contextual Factors, Annabelle Armah

Electronic Theses & Dissertations (2024 - present)

Symptoms of postpartum depression (PPD) are common, particularly for Black birthing parents who may face increased psychosocial risk during the perinatal period. Previous work has demonstrated that PPD can have significant ramifications not only for maternal wellbeing but for infants’ regulatory development. PPD may influence the concordance or mutual influence of biological states between parents and children (i.e., physiological synchrony). Physiological synchrony is thought to be implicated in the development of self-regulation and may be a mechanism through which PPD undermines infants’ emerging regulatory capacities. In Black families, cultural-contextual factors, like racism or cultural practices, may additionally shape birthing parent …

The Role Of The Coach In Student-Athlete Engagement, Christina Cobb

Electronic Theses & Dissertations (2024 - present)

Student engagement has long been recognized as a key indicator of student success in higher education, but limited research has examined engagement within the context of intercollegiate athletics. This qualitative case study explored how college coaches influence student-athlete engagement and how student-athletes utilize athletic department support services designed to promote engagement practices. Guided by Kuh et al.’s (2006) theory of student engagement, this study examined engagement through the lens of time and effort invested in educationally purposeful activities and the institutional environments that support or constrain participation.

Participants included six student-athletes, four coaches, and two athletic department administrators at a …

Examining Ketamine's Differential Impact On Posttraumatic Stress Disorder Symptoms Using The Ptsd Checklist For Dsm-5, Samantha G. Gomez

Electronic Theses & Dissertations (2024 - present)

Posttraumatic stress disorder (PTSD) can be a debilitating and chronic condition. Current gold standard treatments are effective but face high dropout rates. Ketamine therapy is a promising and alternative treatment for those struggling with PTSD symptoms. Prior research has indicated significant reductions in overall PTSD symptoms. However, research regarding symptom-specific changes following ketamine therapy is limited. The present study aimed to extend previous work by MacConnel and colleagues (2025) regarding significant decreases in total PTSD Checklist for DSM-5 (PCL-5) scores following ketamine treatment at an outpatient ketamine center, as well as examine potential symptom-specific changes. A final sample of 142 …

The Effect Of Education On Green Growth And Carbon Emissions, 1990–2022, Soojeong Ahn

Electronic Theses & Dissertations (2024 - present)

The question of whether education promotes economic growth has long been a central topic in development research, and education has been linked to economic outcomes through macro-level pathways such as human capital accumulation, productivity growth, and technological diffusion. More recently, this discussion has expanded beyond economic growth to consider whether education contributes to environmentally sustainable development, particularly green growth. Green growth emphasizes the possibility of sustaining economic expansion while reducing environmental pressure (OECD, 2011; UNEP, 2011), and this study therefore examines how education is related to green growth and carbon emissions at the macro level.

At the macro level, existing …

Despite the growing understanding of therapist factors in client outcomes, there remains limited understanding of the skills that distinguish effective family therapists. The aim of the present study was to assess the interrater reliabilities and factorial structure of a Spanish version of the Facilitative Systemic Intervention Skills (FSIS; Jones et al., 2023a), an observational rating system for evaluating the skillfulness of family therapists in delivering systemic interventions. The FSIS includes eight empirically and theoretically informed systemic therapy skills (Inclusiveness, Empathy for Relational Difficulties, Responsiveness to Safety Concerns, Collaborative Stance, Conceptualizing Family Problems Systemically, Responsiveness to Disparate Goals, Focus on Family …

Intergroup Relationship Attitudes Among Multicultural Adolescents In South Korea: Friendship, Dating, And Marriage, Jeewoo Shin

Electronic Theses & Dissertations (2024 - present)

This dissertation asks how multicultural adolescents in South Korea develop their attitudes toward crossing group boundaries in social and intimate life—whom they would accept as a close friend, a romantic partner, and a spouse—and what factors shape these attitudes. Korea’s immigrant population has grown more than seventyfold since 1990, largely through marriage migration, and the children of those unions are now reaching adulthood. Research on these adolescents has focused on how well they adjust, leaving open how they themselves come to view relationships across group lines.

Using eight annual waves of the Multicultural Adolescent Panel Study (N = 1,112), which …

Warm Mix Asphalt: Key Issues, Performance Challenges, And Modeling Advances, Mahmoud Owais, Marwa Awad

Mansoura Engineering Journal

Warm Mix Asphalt (WMA) has emerged as a sustainable alternative to conventional Hot Mix Asphalt by enabling asphalt production and compaction at reduced temperatures, thereby lowering energy consumption, emissions, and worker exposure to heat and fumes. Despite these advantages, the field performance of WMA remains influenced by technology-specific mechanisms, additive–binder compatibility, aggregate characteristics, moisture susceptibility, compaction quality, recycled material content, and climatic conditions. This review provides a critical synthesis of major WMA technologies, including foamed systems, chemical additives, organic waxes, hybrid additives, bio-based modifiers, and WMA mixtures incorporating reclaimed asphalt pavement. Particular attention is given to how these technologies affect …

Boundaries Of Rules: Social Reactions To Legal Intervention, Francesco Parisi

Articles

This chapter examines what happens at the boundaries of rules: when social practices acquire legal recognition, when legal rules seek to reshape social expectations, and when formal and informal enforcement operate together. The conventional economic model treats the expected formal sanction as the principal source of compliance. Although this model provides a fundamental benchmark, it captures only part of the effects of legal intervention. The taxonomy developed here identifies the different ways in which legal, moral, and social incentives may interact. The kinds of public and private enforcement through which individuals express norms shape the additive, nonadditive, and countervailing effects …

Electrons in matter can rearrange extremely quickly under external perturbations, underpinning subsequent structural and chemical transformations. Coulomb interactions between neighbouring electrons often shape this response, giving rise to correlated motion and strongly affecting the distribution of electrons in the system. Here we show that non-resonant hard X-ray scattering can directly access changes in the radial electron-pair density during the rapid rearrangement of core and valence electrons. We do this by studying sulfur hexafluoride molecules undergoing Auger–Meitner decay. We exploit a second-order interaction between the X-ray photons and the molecules to trigger and probe the decay dynamics with a single pulse, …

School Psychologists As Advocates: Addressing Microaggressions Targeting Students In Schools, Brea M. Banks, Lourdes D. Concepcion-Cabas, Farhia A. Osman, Kendell Kelly

Faculty Publications – Psychology

The aim of this conceptual paper surrounds a discussion of school psychologists’ role as advocates who can combat the prevalence of microaggressions in schools. The authors first define microaggressions in the context of Critical Race Theory and discuss the negative impact these transgressions have on students. Advocacy is a foundational role of school psychologists, and combatting microaggressions is one way school psychologists can engage in such efforts. Given the goal of this special issues is to highlight how social justice advocacy can address critical issues in school psychology, we use the NASP Practice Model as a framework to describe how …

From Nesting To Emergence: Environmental Drivers Of Hatchling Success In Blanding’S Turtles And Implications For Management In Southeast Michigan, Morgan Boyer

Master's Theses and Doctoral Dissertations

Blanding’s turtles (Emydoidea blandingii) are long-lived turtles whose populations are highly sensitive to juvenile recruitment. We used intensive nest monitoring, microclimate logging, soil measurements, and local weather data at two Southeast Michigan sites to quantify how nest placement, incubation environments, and substrate conditions influence emergence success and hatchling condition. Nesting females were morphologically similar in size and produced average clutch sizes for the species (8 ± 2 eggs). Nest sites were found on relatively open, disturbed uplands with sandier soil substrates. Emergence success was generally high (≈ 70-80%) in nests protected from predation. Sandy loam had the highest success rates …

How Directors Of E-Learning Contribute To New Expectations Of Privacy, William R. Jones

Master's Theses and Doctoral Dissertations

This qualitative research study used semi-structured interviews to ask directors of elearning at regional public universities about decision-making concerning new information technologies that affected the data privacy and security of students and staff. The institutional setting and target population were chosen to standardize the inquiry and allow focus on how privacy decisions were made. The conceptual framework drew on Helen Nissenbaum’s theory of contextual integrity for privacy and contributions of behavioral economists on expert decision-making including studies of heuristics and biases, naturalistic decision-making, and the failures of deliberative groups. Data collection involved a first interview and then a second follow-up …

Examining Knowledge And Comfort Levels Of Nursing Students In Providing Sexual Health Education, Deanna M. Gower

Master's Theses and Doctoral Dissertations

Sex education has been a part of the education in the United States for over 100 years. Nursing education is focused on educating nursing students in a comprehensive fashion that develops a safe and competent nurse. Due to the substantial scope of content required in nursing programs, sexual health topics can be pushed aside. This may result in gaps in sexual health knowledge and comfort for nursing students as they may be inadequately prepared to competently address patients’ sexual health needs in clinical practice. The purpose of this cross-sectional descriptive study is to examine nursing students knowledge and comfort levels …

Social Exclusion, Social Support, And Trauma, Eric D. Wesselmann

Faculty Publications – Psychology

Humans have an inherent need to forge stable and quality social connections. One key benefit of having social connections is obtaining social support for navigating traumatic or otherwise stressful events. Ostracism (i.e. being both ignored and excluded, Williams, 2009) and other forms of social exclusion rob individuals of the opportunity to receive social support and likely contribute to stress-related mental health concerns. My colleagues and I tested this premise in different stress-related contexts, ranging from college students struggling with potentially stigmatizing secrets to community members who have experienced various types of traumatic incidents (e.g., miscarriage, military combat). We examined the …

Fishing For Father Relationships: Motivations, Successes, And Barriers To Participating In A Community-Based Program, Jordan A. Arellanes, Kyle Miller, Travis Hicks, Ryan J.S. Liew, Earl Kloppmann

Faculty Publications – Psychology

Fathers who participate in community programs experience a range of positive outcomes, including improved relationships with their children. However, many community programs struggle to gain fathers’ attendance at local events. To counteract this, we utilized Community-Based Action Research in collaboration with local and state agencies to develop a father-specific community program that capitalized on the traditionally masculine parenting activity of fishing. The program educated families on the basics of fishing and then provided them with all the necessary materials. Over the course of three years of data collection, 48 fathers participated in interviews, designed to gain a deeper understanding of …

The Effects Of A Work-Strengths Affirmation Intervention On Death Anxiety, Begüm Orhan, Margaret M. Nauta

Faculty Publications – Psychology

Meaning Management Theory suggests that engaging with meaning-related resources helps individuals constructively regulate consciously experienced death anxiety. Consistent with that theory, we tested whether a single-session, online work-strengths affirmation intervention reduces college students’ (N = 201) death anxiety. Participants completed baseline measures of death anxiety, meaning in life, and self-esteem. One week later, they were randomly assigned to complete either a work-related strengths reflection exercise or a neutral writing task. We assessed outcomes immediately post-intervention and two weeks later. The intervention did not significantly reduce death anxiety in the full sample. Exploratory analyses showed small, immediate reductions among participants …

Shades Of Stress: Colorism As Minority Stress For Women Of Color, Caitlin M. Mercier, Brea M. Banks, Lourdes D. Concepción Cabán, Michelle Duong

Faculty Publications – Psychology

Women of color often endure indignities shaped by colorism and skin tone discrimination, pressuring them to adhere to racialized beauty ideals (i.e., lighter skin). In response, some women of color may internalize these standards (i.e., through internalized coping and racial self-hatred) which can foster psychological distress. Yet, these associations remain underexplored. Using minority stress theory, in our cross-sectional study we collected online survey data to examine whether internalization and racial self-hatred explained the indirect link between colorist microaggressions and psychological distress among 121 women of color at a Midwestern US historically white institution. Using path analysis, we found support for …

PCOM Scholarly Works

Background: The optimal protocol for intermittent androgen deprivation therapy (IAD) in managing biochemical recurrence (BCR) and persistent prostate-specific antigen (PSA) levels after radical prostatectomy (RP) remains undefined. This study aimed to introduce a novel IAD protocol, conduct an initial assessment of the protocol’s effectiveness in real-world settings, and develop a risk-based model to identify patients most likely to benefit from this approach. Methods: This study included 175 post-RP patients receiving IAD, with a median follow-up of 44.77 months [interquartile range (IQR), 31.87–69.50 months] post-androgen deprivation therapy (ADT). The IAD protocol used a PSA threshold of 0.2 ng/mL to define progression …

Therapeutic Landscape Of Early Symptomatic Alzheimer's Disease Translated Into Everyday Practice For Geriatric Providers., Melissa J Bailey-Taylor, Paula Morrow, James Hendrix, Katherine E. Galluzzi, Golnosh Sharafsaleh

PCOM Scholarly Works

Alzheimer's disease (AD) accounts for 60-80% of all dementia cases. Recent advances in diagnostic biomarkers of early symptomatic AD (ie, mild cognitive impairment and mild dementia due to AD) and amyloid-targeting therapies (ATTs) have the potential to improve outcomes for patients with AD. Two ATTs (donanemab and lecanemab) are currently approved and available for use in the US. Both ATTs can slow disease progression as well as cognitive and functional decline in patients with early symptomatic AD. Treatment with ATTs is associated with specific safety concerns such as amyloid-related imaging abnormalities. Therefore, the benefit versus risk profile needs to be …
