Assessing Psychologists’ Clinical Knowledge Of Geriatric Depression: A Validation Study Of The Later Life Depression Knowledge Questionnaire, Abigail J. Laine

Dissertations

Because the US population is rapidly aging, generalist clinicians will increasingly be called upon to provide mental health services to older adults. Unfortunately, most generalist clinicians do not possess the specialized knowledge to provide clinical services to this population and will require training. Professional training efforts are currently hindered by the lack of psychometrically supported scales of clinical disorders specific to aging. Without such scales, it is difficult to evaluate the impact of continuing education programs. The purpose of the present study was to investigate the psychometric properties and scale dimensionality of the Later Life Depression Knowledge Questionnaire (LLD-KQ), a …

As adolescents with TIDM grow older, they are expected to take on more independence in Self-Management (SM) of their diabetes. The poor clinical outcomes of adolescents with diabetes, the onset of …

A “Scary Time” To Be A Man? Comparing Men’S Engagement With Anti-Sexual Violence Discourses In The Private And Public Sphere, Melissa A. Kinsella

Dissertations

The prevalence of sexual misconduct and its consequences for individuals and society remain pressing issues in the United States. While the #MeToo movement has emerged as a prominent response to these challenges, it has faced criticism for emphasizing a singular survivor narrative. Similarly, the study and theorization of sexual violence within sociology have remained limited in scope. This work extends empirical and theoretical perspectives on sexual misconduct by analyzing #MeToo’s utilization in Twitter1 posts from 2017 to 2022, as well as how individuals discuss sexual misconduct in relation to the movement. Additionally, I examine the influence of gender, race, and …

Examining The Current Utilization Of Conceptual Data Modeling In Database Modeling Practices: Mixed Methods Research, Abhishek Sharma

Dissertations

The database system is essential to modern life and helps us in our day-to-day existence, even though it is invisible to us. The most optimal way to architect a new but efficient database is a modeling technique called conceptual data modeling. Despite this importance, research studies have suggested a divergence between actual practice and the ideal expectation from practitioners. Therefore, it was imperative to establish the ground truth in this context and explore the reasons behind the gap between practice and expectation. This mixed-method study used a survey and interviews to establish that only a small fraction of practitioners consistently …

School Psychologists’ Experiences And Roles In Trauma-Informed Practices, Taylor Williamson

Dissertations

Due to a wide breadth of training, school psychologists are uniquely qualified to provide indirect and direct services outlined by best practices, such as school-based mental health services, special education evaluations, and trauma-informed practices. Professional standards indicate that school psychologists are equipped to identify trauma response symptoms and provide evidence-based services when supporting students with trauma histories. However, an identified gap between best practices and the present realities of school psychologists' has been identified in the literature. The few studies that explored the experiences of school psychologists endorsed a lack of training and confidence with identifying trauma response symptoms and …

Like Teacher, Like Student: An Exploration Of Racial Matching On Black Student Identity Development In Secondary Education, Crystal Gloria Lennix

Dissertations

Research on racially matching teachers of color with students of color has demonstrated a plethora of benefits, whether it is in West-Indian teachers with West-Indian students (Warikoo, 2004), Mexicana educators with Mexicana students (Sosa-Provencio, 2019), or Black students with Black teachers (Brooms, 2017). Black teachers are warrior spirits, acknowledging education as a “racial, cultural, linguistic, and spiritual reclamation” for Black students (Sosa-Provencio, 2018). In this study, I sought to understand how the racial matching between Black teachers and Black students can impact Black students’ identity and achievement. Numerous studies say racial matching helps students, but only a few focus on …

Embodied Freedom: Nietzsche On Agency, Health, And Value, Nathan University Berthiaume

Dissertations

This study examines Nietzsche’s views on freedom to show how they inform a notion of human flourishing. I argue that while Nietzsche denies the existence of a metaphysical freedom in which the self is an unconditioned cause of events, he affirms an embodied freedom in which our consciousness can function as part of the causal explanation for action in virtue of its ability to alter the expression of bodily drives. However, I demonstrate that agential power in this sense can only function in conjunction with other causal factors that constitute constraints on freedom. As such, I argue that there is …

Discerning The Role Of Microtubule Acetylation During Hiv-1 Infection, Drew Michael Lichon

Dissertations

The host-pathogen interactions underlying Human Immunodeficiency Virus type 1 (HIV-1) infection are complex and involve the exploitation of host cellular machinery. This thesis investigates the roles of dynein adaptors, microtubule acetylation, and TRIM69-mediated restriction in HIV-1 infection. Through a series of detailed experiments, we explore how HIV-1 utilizes multiple dynein adaptors, such as BICDR1 and Hook3, for intracellular transport, and reveal that these adaptors are critical for efficient viral trafficking. Conversely, the knockdown of Ninein surprisingly enhances HIV-1 infectivity, suggesting a nuanced regulatory role for this adaptor in viral transport. Further, this thesis challenges the prevailing paradigm that microtubule acetylation …

Investigating The Role Of The Nsp15 Amino-Terminal Domain In Nsp15 Function, Viral Replication, And Pathogenesis, Monika Evdokimova

Dissertations

Identifying conserved mechanisms used by viruses to delay host innate responses can reveal potential targets for antiviral therapeutics. Here, we investigated coronavirus nonstructural protein 15 (nsp15), which encodes a highly conserved endoribonuclease (EndoU). EndoU functions as an immune antagonist by limiting the accumulation of viral replication intermediates that would otherwise be sensed by the host. Despite being a promising antiviral target, it has been difficult to develop small molecule inhibitors that target the EndoU active site. We generated nsp15 mutants of SARS-CoV-2 and mouse coronavirus MHV-A59 and identified conserved residues within the amino-terminal domain that are required for EndoU activity. …

Examining The Creative Process Of Visual Artists: A Phenomenological Study, Filiberto Vargas

Dissertations

For this reason, this dissertation explores the creative process of visual artists to better understand how creativity can be cultivated. Visual artists' perspectives and sense-and-meaning-making processes offer a unique view of innovation and creativity. However, there is limited research on the creative processes of contemporary visual artists from culturally diverse …
