Familismo: Exploring A Culturally Sensitive Correlation Between Parentification And Relationship Satisfaction Amongst First Generation Mexican-American Adults Through An Attachment Theory Lens, Ana K. Perez

Dissertations

Parentification refers to the role reversal of children who take on adult responsibility to care for family members. This role is often filled by Mexican-American children as a result of immigration and assimilation. This study explored the relationship between parentification and adult romantic relationship satisfaction among first-generation Mexican-American adults, with particular attention to the moderating roles of attachment styles and perceived unfairness. While earlier research has linked parentification to mental health challenges, few studies have examined its long-term impact on intimate relationships, including relationship satisfaction and experiences of intimate partner violence. A total of 132 participants completed an online survey …

Medication Dosage Calculation: The Impact Of Simulation-Based Deliberate Practice On General Self-Efficacy In First-Quarter Nursing Students, Hasani Green

Dissertations

Medication dosage calculation (MDC) competency is essential for safe nursing practice. However, many prelicensure nursing students experience persistent numeracy deficits, anxiety, and inconsistent preparation, contributing to academic failure and potential patient harm. This Doctor of Nursing Practice project addressed the need for effective early instructional strategies by evaluating the impact of an MDC simulation-based learning through deliberate practice (SBL-DP) intervention on first-quarter Associate Degree in Nursing and Bachelor of Science in Nursing students’ General Self-Efficacy Scale (GSE) scores. Guided by Bandura’s Self-Efficacy Theory, a quantitative, quasi-experimental one-group before-and-after design was used with a convenience sample of students enrolled in a …

Solar Wind - Magnetosphere - Ionosphere Coupling Processes Through Small-Scale Magnetic Flux Ropes, Youra Shin

Dissertations

Small-scale magnetic flux ropes (SMFRs) in the solar wind are examined to determine their properties in the near-Earth upstream region and their effects on geospace. Although SMFRs are observed frequently in the solar wind, their statistical behavior near Earth and their role in solar wind-magnetosphere-ionosphere coupling remain insufficiently constrained. In this dissertation, an automated Grad-Shafranov reconstruction technique is applied to magnetic field and plasma measurements from MMS and Wind, and ionospheric responses are investigated using geomagnetic indices and SuperDARN observations. During the survey period, MMS has an apogee of approximately 25-29 R_E. This orbital configuration allows the near-Earth …

Promoting The Bipartisan Dimension Of Political Leadership: A Study Of The Impact Of A Normative Intervention With Newly Elected Members Of Congress, Jaime M. Ruvalcaba

Dissertations

The U.S. political system is more polarized now than at any time in the past century, as evidenced by the rise of political incivility, legislative gridlock, and hyperpolarization. To date, most studies and efforts have focused on institutional strategies to explain, transform, and mitigate the challenges posed to the political environment. By contrast, little attention has been paid to the normative or values-based behaviors of leaders to either explain or influence political leadership in ways that positively impact the political environment. Fortunately, some organizational programs, like Harvard’s Bipartisan Program for Newly Elected Members of Congress, have taken a different tack, …

A Primary Care Randomized Controlled Trial Investigating The Efficacy Of A Caregiver-Focused Prevention Program For Child Sexual Abuse, Cassandra Dukes

Community Detection In Bipartite Networks Using Bipartite Stochastic Block Models With Node-Level Covariates, Geraldine Elaine Percival

Dissertations

In this age, monumental webs of data demands for perpetual cultivation of ways to untangle these webs of information. One of the many curiosities is how to systematically group entities. When clustering, one avenue to take is ascertaining the interconnectedness between the data points, and gauging their influence to each other. This perspective is programmed to model the relationships between the data presented as a network. Many of the methods being used today are algorithm-based, which may pose limitations in understanding and explaining the uncertainty revolving around the data. Hence, it is proposed to steer towards a model-based approach that …

Bridging The Gap: Action-Oriented Vs. Community-Minded Mentalities And Behaviors In Cold Case Investigation Units, Samantha Strine

Dissertations

One key group in policing that has seen an increase in public and media attention but not research is the cold case investigation unit. These units tend to be more “bureaucratic”, focusing on communication, community-engagement skills, and “desk work”. Thus, this is a potential area for learning techniques and policies that shift the mentalities within police culture to be more accepting of new community focused policies. This study also seeks to address a gap in current research related to studying specialized police units.

The purpose of this study is to describe the organizational dynamics and officers’ tactics, perceptions, and interactions …

Through Their Lens: Co-Teachers’ Effective Strategies That Support Ells And Swds In Mathematics Inclusion Classrooms, Cheryl A. Bentham

Dissertations

Abstract

The current dialogue surrounding minoritized students in mathematics classrooms often focuses on deficit-based narratives that compare their competency to unrealistic norms. Such continuous negative narratives only serve to add another layer of marginalization to students who are already underserved, notably Black and Hispanic students, and subgroups comprising ELLs and SWDs. This qualitative case study explored the research-based strategies utilized by three co-teacher pairs to support ELLs and SWDs in Algebra inclusion classrooms. Vygotsky's (1978) social constructivist theory guided the study, which posits that learning occurs through social interactions, environmental influences, and support from more knowledgeable others. The data were …

Despite comprising a significant portion of the educator workforce, African American women remain underrepresented in school leadership positions nationally, warranting deeper examinations of their professional pathways and daily realities. This qualitative study employed interpretative phenomenological analysis, guided by an intersectional framework, to understand the lived experiences of 10 African American female educational leaders across K–12 settings in Georgia. Principals, assistant principals, instructional specialists, and a superintendent engaged in semi-structured interviews analyzed through …

Ai You Can Trust: Understanding The Role Of Structural Assurance And Situational Normality In The Use Of Generative Ai, Olushola Bunmi Abayomi

Dissertations

The rapid growth of generative artificial intelligence (GenAI) has increased its use in productivity, content creation, and decision support; however, adoption depends on user trust, as GenAI performs tasks that are often associated with human judgment. Drawing on the Trust in Technology Model, this dissertation examines how structural assurance and situational normality influence Trust in GenAI, and how Trust in GenAI affects trusting intentions and users' willingness to depend on GenAI. Structural assurance and situational normality, captured through several factors, were modeled as antecedents of Trust in GenAI and, in turn, trusting intentions. The model was tested using survey-based experimental …

Identifying The Threshold: Using Regulatory Focus As A Predictor Of Ceo Adaptibility During Environmental Changes, George B. Constantine Iii

Dissertations

Building on research on CEO turnover and strategic leadership, this study examines how decision makers' regulatory focus shapes strategic decision-making and how this can contribute to performance decline, often resulting in CEO replacement. Drawing on regulatory focus theory, the study theorizes that measurable chronic regulatory focus attributes influence decision makers’ capacity to adapt to environmental change—conditions under which prior research suggests executives may become rigid and persist with established strategies. Despite its relevance for strategic adaptation, such chronic trait behavior has received limited attention in the current business literature. To address this gap, effectuation theory is integrated into a simulation-based …

Severity-Informed Analysis Of Staff-Worn Personal Protective Equipment Use In An Applied Behavior Analysis Clinical Setting, Trey Ximenez

Dissertations

Staff who provide care for individuals with autism spectrum disorder and intellectual disability experience high workplace injury rates, particularly in applied behavior analysis settings (Hardesty 2020; Hardesty et al., 2025; Romani et al., 2020). Despite these elevated risks, organizations lack evidence-based criteria for determining what protection to recommend to staff based on documented injury outcomes (Irwin Helvey et al. 2024). This study examined how staff injury characteristics are associated with staff-worn personal protective equipment (PPE) use in an inpatient neurobehavioral unit. A retrospective analysis of 1,998 staff injury incidents from 105 patients (2020-2024) tested whether injury severity, injury type relevance, …

Knowledge, Physician Communication, And Psychological Predictors Of Willingness To Engage In Dementia Risk Reduction Across The Lifespan, Thomas Fisher

Dissertations

Dementia represents a growing global public health concern, with increasing evidence suggesting that a substantial portion of dementia risk may be attributable to modifiable lifestyle and health-related factors. However, relatively little is known about public knowledge of these risk factors, willingness to engage in dementia risk reducing behaviors, and psychological factors that may be associated with willingness. The present study examines these factors among adults living in the United States across the lifespan. Participants (N = 308) completed an anonymous online survey assessing dementia risk-factor knowledge, willingness to engage in dementia risk reducing behaviors, primary care provider communication regarding dementia …

Love’S Dialects: Proposed Additions In Emotionally Focused Therapy For Intercultural Couples, Nicola Heurich

Dissertations

Intercultural romantic relationships have become an increasingly prominent feature of contemporary society due to globalization, migration, and cross-cultural exchange (Livingston & Brown, 2017). However, these partnerships are also associated with elevated levels of relational distress and higher rates of conflict, separation, and divorce, underscoring the need for culturally responsive approaches in couple therapy (Bustamante et al., 2011; Genç & Su, 2021).

Research on intercultural couples remains limited both within and beyond Emotionally Focused Therapy (EFT), and despite increased recognition of cultural factors, there is still insufficient guidance on navigating differing cultural contexts within a dyad (Linhof & Allan, 2018).

Power Signature-Based Hardware Security Techniques For The Internet Of Things, Ashish Mahanta

Dissertations

The rapid proliferation of the Internet of Things (IoT) has introduced significant security challenges, particularly concerning stealthy, instruction-level malicious code injections that evade traditional software defenses. While conventional power analysis techniques are highly effective at detecting such subtle abnormalities, they require capturing high-resolution, voluminous power trace data. This dependency necessitates bulky data acquisition (DAQ) instrumentation, power-hungry analog-to-digital converters (ADCs), and intensive computational resources, making these methods impractical for deployment on resource-constrained IoT devices. To bridge this critical gap, this dissertation presents a novel hardware security paradigm, the Power Rising and Descending Signature (PRIDES) methodology. Instead of quantizing actual power consumption …

Exploring the guru shishya parampara ((गुरुिश� पर�रा), a pedagogical tradition with roots in Vedic culture, through the lived experiences of an expert musician, this study relates immersive experiences to personal transformation. Data from interviews, lectures, and articles were analyzed. From the data, immersive experiences of the guru shishya tradition are understood to be embodied, intrinsic, …

America The Monstrous: The Birth Of American Horror Fiction In The Long Nineteenth Century, Rachel Kietzman

Dissertations

American gothic works that center the affect of horror explore themes of abjection, inhumanity, and monstrosity that impede a coherent expression of American identity. By approaching these works through the lens of horror rather than only as Gothic works, a picture ofa visceral, embodied becoming takes shape: America is a monstrous birth in the most literal sense of the word, a sign and demonstration that unity and uniformity are not the same, that wholeness does not require conformity, and that political choices are paid for in flesh. In short, American horror fiction is the head of Medusa, an apotropaic sign …

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 …

Coming To The Table: How Black Mamas Resist And Reorganize The Racialized Educational Terrain In Community, Moriah Lynn Johnson

Dissertations

Black homeschooling has grown significantly among African American families, yet existing scholarship has not fully theorized how race, gender, and institutional power operate within homeschooling communities. My dissertation examines how Black mothers resist and reorganize a racialized educational terrain that extends beyond conventional schooling into homeschooling spaces. Drawing on Diamond’s (2006) racialized educational terrain framework, I introduce the Racialized Homeschooling Terrain (RHT) — an original conceptual framework that demonstrates how homeschooling spaces are racialized in similar and distinct ways. This framework centers Black maternal agency, as moms interpret, resist, and reorganize homeschooling spaces to construct communal homeplace. Using a qualitative, …

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 …
