Through The Lens Of Social Media: Examining The Relationship Between Exposure To Social Media Videos Of Police Misconduct And Perceptions Of Legitimacy And Cooperation With Campus Police, Kamal Alhassan

Theses and Dissertations

This dissertation examines how exposure to social media and internet news videos depicting police misconduct influences college students' perceptions of campus police legitimacy, procedural justice, and willingness to cooperate. Although prior research has demonstrated the impact of media portrayals on perceptions of municipal police, limited attention has been given to campus policing contexts. Guided by Tyler’s process-based theory of police legitimacy and Gerbner’s cultivation theory, this quantitative study surveyed 400 students at a large public university in the Southeastern Mid-Atlantic region. Measures included self-reported viewing and engagement with police misconduct content on social media, internet, and traditional media platforms, as …

Imagine Being Free: Decolonizing Actor Training In University And Conservatory Programs, Hope R. Ward

Theses and Dissertations

While blackface is considered the first proper form of American theater, I want to consider how the auction of enslaved Africans functioned as the original form of American theater. The auction block acted as a kind of interactive performance in which enslaved bodies were surveilled and evaluated as a kind of spectacle. In many ways, the auction block inaugurated White viewing practices of the Black body that reverberated in the day-to-day practices of slavery and subsequent visual media like the refashioning of blackface minstrel tropes within contemporary entertainment (plays, television, film). In Imagine Being Free: Decolonizing Actor Training in University …

Development Of A Mediation Model Of Pain Cognition In Adult Patients With Sickle Cell Disease, Daniel M. Sop

Theses and Dissertations

Pain is a hallmark of Sickle Cell Disease (SCD), a genetic hemoglobinopathy characterized by chronic hemolytic anemia, vaso-occlusion, and organ damage. While acute vaso-occlusive crises (VOC) have been extensively studied, the mechanisms underlying chronic pain and its interplay with brain function remain unclear. This dissertation investigates the relationships between cerebral blood flow (CBF), fluid cognition, and pain sensitivity in adults with SCD, utilizing advanced imaging techniques and validated assessment tools.

Arterial spin labeling (ASL) and functional magnetic resonance imaging (fMRI) were employed to measure CBF and brain activity, respectively. Pain sensitivity was assessed using the Pain Sensitivity Questionnaire (PSQ), and …

Cannabis Use Among Cancer Survivors And The Impact On Cancer-Related Pain, Tiffanie A. Vargas

Theses and Dissertations

With a growing population of older adult cancer survivors—many of whom experience cancer-related pain—interest in medical cannabis as a pain management strategy has increased. This secondary analysis used data from the 2022 U.S. Behavioral Risk Factor Surveillance System (BRFSS) to examine cannabis use behaviors among cancer survivors and assess associations with cancer-related pain. The study had three aims: (1) to describe 30-day cannabis use (prevalence, intensity, and administration routes) by chronic health condition and cancer diagnosis, focusing on non-melanoma skin cancer, melanoma, and other cancers; (2) to compare demographics, health characteristics, and tobacco use by cannabis use status among cancer …

Food Waste Renaissance: From The Table, For The Table, Yasamin Shaikhi

Theses and Dissertations

What if waste could be seen as a valuable resource rather than a burden? Food Waste Renaissance (FWR) explores innovative ways to transform excess food and byproducts into sustainable design materials. In Qatar, where food waste constitutes approximately 60% of urban waste, FWR promotes a shift in perception rather than attempting to resolve large-scale waste management issues. By fostering a culture where surplus becomes a resource, it inspires individuals, designers, and communities to embrace and contribute to a circular economy. FWR examines rice and date byproducts as biodegradable raw materials for lamps, bringing material from the table back to the …

Existing In The Context: A Conjunctural Analysis Of Kamala Harris Memes, Amaya Mcneal

Theses and Dissertations

Political memes have become a common way for people to express their political views online, helping politics reach young adults who weren’t previously interested. Consequently, politicians have begun sharing and creating memes themselves. The memeification of American politics has diminished debate about ideas, ideals, issues, and people’s vital interests, debasing voters by treating them not as citizens but as passive “consumers” and “spectators” of mediated politics. This paper helps make sense of this crisis, focusing on the example of former Vice President Kamala Harris. Vice President Kamala Harris' memeified presidential campaign during the 2024 U.S. election targeted voters through a …

Reply Stop To Stop, Molly A. M. Garrett

Theses and Dissertations

Over the course of 8 years working in progressive political strategy, 2015–2023, I became increasingly critical of the systems, formulas and tools we were using to communicate with voters. Reply STOP to Stop is documentation of my time at graduate school, of wrestling with ideas of political design, language, communication and distribution. I analyzed my past work — all the texts, emails, social media posts, print ads, web banners, videos and other miscellaneous scripted content — and wondered if we would all be better off without it. Would elections be fairer, would there be less fake news, more community building? …

Enhancing Clinical Trial Matching In Molecular Diagnostics: Using Natural Language Processing And Clustering Approaches In Hematological Malignancies, Gillian Fanning

Theses and Dissertations

Clinical trial matching is a critical component of personalized medicine, particularly in the management of hematologic malignancies. At Virginia Commonwealth University (VCU) Health, the Molecular Diagnostics (MDX) Lab produces somatic variant reports and recommends clinical trials based on the presence of clinically significant mutations. However, the current manual trial recommendation process is time-intensive and lacks scalability.

This study introduces a computational framework to streamline and standardize clinical trial matching using natural language processing (NLP) and unsupervised clustering. Trial brief descriptions were analyzed to extract frequent terms, and trials were grouped based on term similarity using joint dimensionality reduction and clustering. …

Using A Dimension Reduction Approach To Parse Heterogeneity In Dietary Restriction, Amanda Makara

Theses and Dissertations

Dietary restriction, the problematic reduction of caloric or macronutrient intake, is a critical eating behavior occurring transdiagnostically across eating disorders and subclinical disordered eating. The definition of dietary restriction is highly heterogeneous, and restriction is often conflated with other distinct constructs, such as dietary restraint. The current practices related to the definition and measurement of dietary restriction have notable flaws, negatively impacting the ability to identify and establish risk, diagnosis, and treatment of eating disorders. There is also limited evidence that commonly-used dietary restriction measures can validly predict food choice and objective intake. These issues raise questions about whether dietary …

“You’Re Only As Good As Your Resources”: Exploring Virginia Police Chiefs’ And Sheriffs’ Decisions As Public Administrators To Engage In Community Collaborations With Domestic And Sexual Violence Agencies, Christine E. Wengloski

Theses and Dissertations

The collaborations between domestic and sexual violence victim-serving agencies (DSVAs) and law enforcement agencies help connect victims of crime to needed services. To maximize the benefits of these victim-serving initiatives in Virginia, it is imperative that victim-serving agencies understand the perceptions and factors that influence the decision-making of law enforcement administrators. In this study, I first present a theoretical framework of Herbert Simon’s Decision-Making Theory as a guide to understanding police chiefs and sheriffs as public administrators. A review of the literature demonstrates gaps in existing scholarship around chiefs’ and sheriffs’ decision-making about domestic and sexual violence victim-serving initiatives. Next, …

Learning And Identity In Cross Functional Teams: A Communities Of Practice Perspective, Penelope K. Mcfarline

Theses and Dissertations

Cross functional teams (CFTs) are groups of diverse professionals leveraged by organizations to address a variety of complex issues. While CFTs have the potential for rapid problem solving, product or service innovation, and knowledge creation, they sometimes underachieve or fail to meet their goals at great cost to the organization. Prior research points to the barriers that diverse professional identities create to CFT performance and learning. This study aims to explore the relationship between the professional identities of cross functional team members, and what and how they learn. A conceptual framework for the study sought to view a CFT as …

Theses and Dissertations

This dissertation explores discursive functions of disability in pupil placement decisions in Massive Resistance Virginia, the relationship between disability and race that was constructed through these moves, and how these relationships surface in the reflections, perceptions, and pedagogy of a practicing art teacher, Nathan, who works at Arts High School (AHS), a Virginia specialty center high school. Under the umbrella of the Discourse Historical Approach, which relies on multiple, interdisciplinary data sources to explore how discourses evolve, I connect a robust archival analysis of historical data collected in the records of Virginia’s Pupil Placement Board (746 boxes, 1956-1966) with present-day …

Liner Notes On Black Trans Girlhood: Afrofuturist Affect & Black Popular Music As A Praxis Of Self-Fashioning, Shawn J. Williams

Theses and Dissertations

Liner Notes on Black Trans Girlhood: Afrofuturist Affect & Black Popular Music as a Praxis of Self-Fashioning interprets Black musical performance in identity-making, with a focus on how music and Black trans identity intersect and informs Black trans girlhood. As such, Black trans girls render ourselves legible, i.e. understood without shame or judgment, by constructing our identities through the music by Black women we listen and dance to, or watch and sing. These musical connections affirm the possibilities of Black femme expression. This expression of Black femininity is due to what I call an Afrofuturist affect, by which I refer …

Place, Culture, And Care: A Socioecological Examination Of Type 2 Diabetes Among Hispanics In The U.S., Danielle Montoya

Theses and Dissertations

Introduction: Type 2 diabetes (T2D) disproportionately affects U.S. Hispanic populations. This dissertation examined whether structural determinants fundamentally drive T2D disparities among Hispanics, with attention to within-group racial heterogeneity.

Methods: Three studies utilized nationally representative data. Study 1 examined neighborhood segregation and ethnic enclave residence associations with T2D using restricted NHANES data (2011-2018, n=5,056). Study 2 investigated acculturation and T2D associations using restricted NHANES data (2011-2018, n=4,540). Study 3 analyzed patient-provider racial/ethnic concordance and adequate diabetes care using MEPS data (2008-2021, n=17,138).

Results: Structural factors demonstrated primacy across all studies. Neighborhood segregation (aOR=1.17, p>0.05) and ethnic enclave residence showed no …

Characterization Of Outer Surface Protein C Of Borreliella Role In Host Tropism, Kathryn Mf Chambers

Theses and Dissertations

The Lyme disease spirochetes, Borreliella spp., are maintained in nature through a complex enzootic cycle involving Ixodes ticks and a diverse set of reservoir hosts. The outer surface protein C (OspC) of the bacterium is an essential virulence factor required for transmission from ticks and early infection of mammals. Deletion of ospC abolishes infectivity, yet the precise molecular mechanisms underlying OspC function remain incompletely defined. In this dissertation, I examined the contribution of OspC type identity to host specificity. OspC is highly diverse, with over 30 genetically stable types described. While intra-type sequences are conserved (>95% amino acid …

Between "Hippies In Suits" And "Money Is The Name Of The Game": Farm Animal Advocates' Analyses Of Political Power In The Farm Bill, Jeff Thomas

Theses and Dissertations

The animal agriculture industry annually slaughters roughly ten billion land animals in the United States. What can be done to improve their welfare and lessen their suffering?

Over the past decade, the problem of farm animal welfare and suffering has drawn increasing interest from the effective altruism community, a loose movement of utilitarian advocates seeking technocratic solutions to social problems (Singer, 2015). As effective altruism has become a more potent driver of the animal welfare movement, an increasing number of nonprofits have begun engaging in political advocacy for farm animal welfare. Facebook co-founder Dustin Moskovitz’ Open Philanthropy is the largest …

Subgingival Microbiomes Of Healthy And Periodontitis Subjects, Tareq Abdulrasoul

Theses and Dissertations

Background: Periodontitis is a common chronic inflammatory disease triggered by the dysbiosis of the subgingival microbiome. 16s rRNA sequencing has been used to profile the subgingival plaque samples in healthy and periodontitis subjects. Here, we have collected subgingival plaque samples from subjects and analyzed the microbiome profile from 16s rRNA sequencing. We hypothesized that periodontitis patients will have a different subgingival microbiome profile than that of healthy subjects.

Methods: Subgingival plaque samples were collected from periodontitis and healthy subjects who were indicated for periodontal surgeries (osseous resective and regenerative surgery for periodontitis patients or crown lengthening for healthy …

Self-Threat And The Anchoring And Adjustment Heuristic, Mattie V. Hedgebeth

Theses and Dissertations

Since its introduction in 1974, the anchoring and adjustment heuristic has been a topic of interest within the field of decision making. Although much work has examined factors that affect the process of the anchoring and adjustment heuristic, very little has been studied about how self-processes that may influence adjustment from an anchor. More specifically, the role of self-threat as a possible motivating factor in the adjustment process had yet to be explored. In my previous research, I explored how anchors that are threatening or flattering to one’s ingroup influences how they adjust from said anchor. Participants adjusted to an …

Radical Hope Amid Generational Oppression And Puerto Rican Well-Being, Natalia Gomez Giuliani

Theses and Dissertations

Oppressive systems (e.g., colonialism, racism, capitalism) create a disparate distribution of power that, through various mechanisms, negatively impacts the health and well-being of members of the oppressed group. Boricuas have experienced over 500 years of oppression, with the island currently maintaining a colonial relationship with the United States. As these adverse effects of oppression are identified, the need for protective factors (e.g., hope) has emerged. This study explored how islander Boricuas practice radical hope, understand their history of oppression and resistance, and how they perceived it to impact their overall well-being. Utilizing a phenomenological qualitative approach, I conducted 15 semi-structured …

Swarming Segregation: Leveraging Swarm Intelligence And Regionalization As Instruments For School District Desegregation, Jeffrey Wooten

Theses and Dissertations

Even after Brown led to the South briefly having the most diverse schools in the nation, schools throughout the Northeast have remained the most segregated in the nation for decades. While federal jurisprudence has made compelling desegregation pursuant to the Equal Protection Clause more challenging, New Jersey has a particularly favorable landscape to address severe segregation. With a highly diverse, densely populated public enrollment, favorable state constitutional precedent, and a history of successfully compelling desegregation, New Jersey is fertile ground exploring regional desegregation. Scholars, judges, and even plaintiffs in ongoing litigation (Latino Action Network v. N.J.) have called for New …

Infinite Finite: A View On Human Progression Through Emergent Generative Systems, Fatima Abbas

Theses and Dissertations

Contemporary crises reveal an imbalance in human progression, prioritizing material advancement while neglecting ethical, compassionate, and spiritual dimensions. This thesis examines natural progression through the lens of emergence, where simple interactions produce complex outcomes. Analyzing natural patterns across different scales, from cosmic formations to neural interactions, underscores emergence's universal nature.

Within this context, Infinite Finite introduces a generative digital tool simulating emergence through iterative cycles of construction and deconstruction. Depicting a century of human progression informed by historical behaviors via simulated cellular interactions, the tool visually differentiates ethical from unethical progression. This is represented through ten data visualization tiles composed …

Crafting Futures: Balancing Tradition And Technology In Craft Practices, Saga Elkabbash

Unleashing Serine Palmitoyltransferase In Test Tubes And Mice, Matthew W. Peart

Theses and Dissertations

Canonically known both for structural contributions to lipid bilayers and roles in cell signaling, the sphingolipids comprise a dynamic, multifaceted class of molecules which are studied to understand homeostatic cell biology as well as pathophysiology. Sphingolipids contribute to tissue-specific structures such as myelin, a multilayer membrane that allows for rapid conduction of action potentials along neuronal axons. All sphingolipids are downstream products of the rate-limiting and initiating enzyme in the de novo sphingolipid synthesis pathway, Serine palmitoyltransferase (SPT). Demonstrative of its status as the enzyme that catalyzes a crucial step in a biochemical pathway, SPT activity is strictly regulated. This …

Machine Learning Models Leveraging Patient-Similarity And Clinical Temporality For Disease Prognoses, Ahmad F. Al Musawi

Theses and Dissertations

Electronic Health Records (EHRs) constitute a comprehensive and high-dimensional repository of clinical data, encompassing a wide array of patient-level information such as diagnoses, procedures, medications, laboratory results, and unstructured clinical narratives. These data hold immense potential for advancing predictive modeling in healthcare, including tasks such as disease progression modeling, hospital readmission prediction, and length of stay (LoS) estimation. However, the intrinsic complexity of EHR data—manifested in its heterogeneity, sparsity, and temporal dynamics—poses significant analytical challenges that limit the generalizability and interpretability of conventional machine learning models. Recent methodological advancements in deep learning and graph-based learning, particularly Graph Neural Networks (GNNs), …

How To Touch Your Bile, Aleckxi Dorhofer

Theses and Dissertations

I have been reflecting on my past decade-long struggle with anorexia and bulimia. Reinterpreting this experience through the lenses of mythology and magic, I have constructed these Stygian carcasses (from the river Styx, which serves to separate the living and the dead) using my own bodily proportions in muslin, an intermediary material which requires transformation. In this work, I utilize these forms to symbolically rot for me as my body did, performing a type of sympathetic magic (magic worked from afar on another person) on myself, extending my life and allowing all which occurs between birth and death to affect …

Profiles Of First-Year First-Generation Students’ Library Perceptions And Use: An Intersectional, Mixed Methods Study, Megan Hodge

Theses and Dissertations

To effectively support first-generation students, academic libraries must understand their needs. However, limited library research has been conducted into how these students, who often embody multiple structurally disadvantaged identities, perceive and use academic libraries or how their intersecting identities manifest in differing library needs. This study aimed to build understanding of first-year first-generation students’ perceptions and use of academic libraries. To do so, the researcher used an explanatory sequential mixed-methods design. First-year first-generation students at Virginia Commonwealth University were surveyed using Winkler and Sriram’s (2015) Academic Capital Scale and Anwar et al’s (2012) AQAK: Library Anxiety Scale for Undergraduate Students. …

Learning From Non-Stationary Data Streams, Gabriel Jonas Aguiar

Theses and Dissertations

The rapid growth of data from sources such as mobile applications, sensors, and network monitoring has increased the need for machine learning algorithms capable of handling non-stationary data streams. However, learning from such streams presents significant challenges due to their evolving nature and the presence of concept drift. One of the most complex issues is learning from imbalanced data streams, where shifting data distributions, combined with feature space drifts, complicate continuous adaptation. These challenges become even more pronounced in multi-class scenarios, which are common in real-world applications. Detecting concept drift in such contexts is particularly demanding, as it requires tracking …

Exploring Prenatal Cannabis Use Among Young Pregnant Bisexual Individuals: A Mixed Methods Study, Nicole Boss

Theses and Dissertations

The perinatal period is a critical time for health behaviors with outcomes that have short- and long-term effects for both childbearing person and child. Research indicates that young bisexual people are at greater risk of unintended pregnancy, experience psychosocial health disparities, and may be more likely to use cannabis during pregnancy. Few studies have examined this phenomenon. This study is a secondary analysis of mixed methods data from a longitudinal cohort study. Thematic analysis of qualitative data (n=12) revealed the contextual adaptivity of cannabis use, with participants explaining the situations and rationales which motivated their cannabis use changed over time. …
