Your Left Or Mine: A Journey To Accessibility For Learning Disabilities And Neurodivergence In Stage Combat Pedagogy, Ambria Campbell

Theses and Dissertations

This thesis examines stage combat pedagogy from its inception to the present day through the lens of accessibility for learning disabilities and neurodivergence. Relevant research in education as it relates to disability is analyzed and applied to the field of stage combat pedagogy. What follows is a deconstruction and reconstruction of beginning level stage combat pedagogy to increase accessibility. These ideas are then tested and the results reflected on. This thesis focuses on college level and aged students who are the most likely demographic for beginning stage combat students. The completion of this thesis does not represent an endpoint in …

Medical Linear Accelerator Water Tank Measurements Optimization For Commissioning, Tyler R. Laugh

Theses and Dissertations

Beam commissioning is a critical component of linear accelerator (LINAC) implementation, requiring accurate measurement of percent depth dose (PDD), beam profiles, and output factors across a wide range of field sizes. Conventional commissioning workflows often require multiple detectors and can be time-intensive, particularly for small-field dosimetry where measurement accuracy is highly sensitive to detector characteristics. This study evaluated the performance of a plastic scintillation detector (BP-PSD) for full water tank commissioning and its potential to improve efficiency while maintaining dosimetric accuracy.

Beam data were acquired for field sizes ranging from 1 × 1 cm² to 40 × 40 cm² using …

Towards Sample-Efficient Deep Reinforcement Learning, Guang Yang

Theses and Dissertations

Deep reinforcement learning (DRL), combining reinforcement learning and high-performance function approximations such as deep neural networks (DNN), is a powerful approach to solving complex sequential decision-making problems. However, due to the complex solution space of the sequential decision-making problems and the inefficient design of the DRL algorithms, DRL algorithms usually require a prohibitively large number of data samples to train effective strategies. Consequently, it is difficult to apply these DRL algorithms to complex real-world problems that require high costs to collect a large volume of data samples. This dissertation proposes new mechanisms to address this sample inefficiency issue, realizing sample-efficient …

An Integrated Data-Driven Framework For Arctic Shipping: Analyzing Vessel Speed, Environmental And Ecological Factors Through Innovative Statistical Spatio-Temporal Methods, Inverse Optimization And Machine Learning, Mauli Pant

Theses and Dissertations

This dissertation develops an integrated data-driven framework to analyze vessel navigation and ecological risk in the United States Arctic from 2010 to 2019. As environmental change and maritime activity increase in the region, understanding how vessels respond to dynamic conditions and how those responses interact with marine ecosystems has become increasingly important. A central theme of this dissertation is the treatment of vessel speed as both an observed outcome and a decision variable reflecting trade- offs among operational, environmental, and ecological factors. The first chapter develops a predictive framework for vessel speed over ground (SOG) using Gaussian Process Boosting (GPBoost), …

Gz17.602, A Combination Of Three Nutraceuticals, Interacts With Carboplatin And Etoposide To Kill Neuroblastoma, Michael R. Booth

Theses and Dissertations

This study examined the efficacy of GZ17.602, a combination of Harmine, Isovanillin, and Curcumin as a therapeutic for MYCN-amplified Neuroblastoma, both alone and in combination with standard of care chemotherapeutics. This was done due to the low survival rate associated with these neuroblastomas, the large degree of morbidity associated with current treatments, previous experiments in the Dent lab having shown 602 as effective for killing cancers of other types, and the current lack of understanding of the biology of GZ17.602 in solid pediatric cancers. Due to the GZ17.602 components being present at different concentrations in tumors than those administered, the …

Student Centered Approaches To Analyzing Engagement And Discourse, Kamil Hankour

Theses and Dissertations

Student engagement and participation in classroom discourse are widely recognized as powerful predictors of meaningful science learning, yet students’ own perspectives on the factors that shape their engagement and participation are currently underexamined. Prior research has established strong links between engagement, discourse and outcomes such as academic achievement (Bae & DeBusk-Lane, 2019; Fredricks et al., 2004; Sedova et al., 2019), but less is known about how students understand and interpret their experiences across individual, group-level and classroom contexts, particularly within historically marginalized populations (Cook-Sather, 2013; Schaefer et al., 2024). This three paper dissertation advances a line of inquiry integrating a …

Regulation Of Tgf-Β1–Induced Epithelial–Mesenchymal Transition By Integrin Inhibition, Wesam Elhawabri

Theses and Dissertations

Epithelial–mesenchymal transition (EMT) is a critical process underlying cancer progression, fibrosis, and tissue remodeling, characterized by coordinated changes in cell morphology, nuclear structure, and extracellular matrix (ECM) organization. Transforming growth factor beta 1 (TGF-β1) is a primary inducer of EMT; however, the extent to which integrin-mediated signaling and ECM remodeling regulate these structural changes remains incompletely understood. In this study, we quantitatively investigated EMT-associated remodeling in A549 lung carcinoma cells and MCF10A epithelial cells following TGF-β1 stimulation. Cells were cultured on ECM-coated substrates and treated with TGF-β1 in the presence or absence of integrin-targeting inhibitors (ATN-161, 28-G11, and STX-100). Im …

My Mouth Is A Glutton, My Mouth Is A Lover., Cole Kamerick Eller

Theses and Dissertations

This thesis is a reflection on my relationship with jewelry. I discuss the impact of jewelry

and its materials. What are the ramifications of these objects? Politically, socially, and

spiritually. I reflect on material agency, cultural unconscious, and value systems, and

how I relate to jewelry, my love for it, and my grief for it. This work is the result of ritual

and impulse. The writing is my reflection on the results of that ritual.

Daisyworld, Eva Foldy

Theses and Dissertations

Daisyworld explores how painting can represent ecological and sociopolitical crisis without relying on narratives of total collapse as a catastrophic end, instead framing the present as a condition of ongoing, uneven transformation. Drawing on ecological models of adaptation, interdependence, and planetary self-regulation, it uses plant fasciation as both a biological reference and speculative metaphor for distorted yet generative forms of survival. Situating painting within a broader history of visual culture, it examines how images function as accessible systems of knowledge while challenging colonial and human-centered modes of representation. In dialogue with contemporary, systems-based artistic practices, the project repositions painting as …

Tangled Up In Blues, Clara B. Deweese

Theses and Dissertations

Martin Buber’s philosophy teaches us that when our masks fall and our armor’s unveiled, we discover humanity shared. Tangled Up in Blues unpacks the snapshot photographic practice I’ve had for years, which documents my mutually uplifting relationships, and is presented for my thesis exhibit through a painterly technique that deconstructs and reconstructs  the images onto wood panels using laser transfer. As we navigate a distracted and fragmented society made of greed and bigotry, cherishing the deep connections and shared memories brings us optimism.

Light And Unseen, Daša Kulikova

Theses and Dissertations

This thesis is a body of paintings and two poetic fragments. Shaped by distance and displacement, the work finds its ground in the tension between the desire to be free from the past and heal, and longing for home and connection. Painting practice becomes an event of contact with what is lost, or unclear, or in the process of becoming through accumulating layers, marks, erasures, and traces of the process of its making.

Psychological Richness From Shared Experiences In Romantic Relationships: The Moderating Role Of Attachment, Sae Y. Kim

Theses and Dissertations

Psychological richness, defined by experiences that are novel, complex, and perspective changing, has been proposed as a third dimension of the good life alongside satisfaction and meaning. Although prior work has focused on richness at the life level, romantic relationships may be an important context in which psychologically rich experiences occur. In Study 1, a correlational study, adult attachment was associated with psychological richness in life, such that secure attachment was positively related to psychological richness, whereas anxious and avoidant attachment were negatively associated. Informed by the results of this study, I designed Study 2 to be a 4-day daily …

There Is A Puddle In Stonehenge, Nathaniel Newcomb

Theses and Dissertations

I began by making what I called "furniture": finding discarded logs and using a chainsaw, I milled out slabs of wood far larger than any normal board or beam, and gave them the function of chair, table, shelf. Sometimes it was a "shelf" in name only, and was commentary on furniture. In my practice, using discarded wood is necessary for the sake of the earth; making original pieces is necessary for the sake of my soul. I am reminded of megaliths when I erect these enormous forms in wood. I make intuitively, and like the meaning of megaliths, obscured by …

Spilt Milk, Fatima Kaleem

Theses and Dissertations

Spilt Milk explores how institutional discipline is rehearsed across the Pakistani home, school, and television soap opera. These seemingly domestic spaces converge at the military-industrial complex, where media propaganda (ISPR) and consumer commodities collaborate to manufacture a unified national identity.

Through an installation of school desks and re-fabricated cereal boxes, this project examines the ‘cereal/serial’ as a site of ideological consumption. By refabricating these boxes with embroidery, drawing, lace, and synthetic hair, the work subverts state-mandated narratives. These material interventions replace assembly lines with spills of hair and sweat to highlight the vulnerability of the body under surveillance. This project …

Sensory Constellations, Madaline K. Gardner

Theses and Dissertations

This thesis situates neurodiversity within the field of fine arts by integrating disability studies, institutional critique, and material practices in painting and printmaking. Through visual analysis and studio-based research, the project examines how tactile engagement, color relationships, and repetitive mark-making can articulate embodied experiences of neurodivergence. It challenges dominant institutional frameworks that pathologize neurodivergent behaviors by reframing stimming as a generative and communicative practice. The resulting body of work includes both image-making and the creation of tactile objects designed to facilitate sensory interaction. The thesis proposes alternative ways of understanding artistic practice and accessibility within art institutions.

All Other Ground Is Sinking Sand, Kevin Hopkins

Theses and Dissertations

My thesis project, All Other Ground Is Sinking Sand, is a body of work that frames soft sculpture as "prophetic charm" and collaborative performance as the ceremony that charges them. In this essay, I will explore the conceptual chronology of the charms, their connection to the notion of décalage, and their potential to compel witnesses toward the immediate liberation of queer, Black individuals.

With my research centered on the necessity of shifting cultural responses to enduring racial trauma, I focus my work on deconstructing Black hypermasculine archetypes shaped by white supremacy and unpacking the tension between individual autonomy and social …

Between The Veins: Materializing Memory In The Age Of Digital Storage, Alice Mohammed Aslem

Theses and Dissertations

What happens to a childhood stored behind a password? This thesis began with a simple moment of scrolling through my son’s photographs on my phone. As the images multiplied, they began to lose clarity, turning into an overwhelming digital archive. This made me ask: What kind of memories am I preserving for him?

Having grown up between analog and digital worlds, Between the Veins explores how I navigate memory through material objects and digital archives. Using weaving, images are transferred onto screw pine and palm leaves. In this process, digital files of his childhood are translated into organic fibers of …

Timing And Stability Of Uav Operations In Smart City Environments: Experimental Analysis And Design Implications, Rabia Ipek Yasar

Theses and Dissertations

This thesis investigates the deployment and performance of unmanned aerial vehicles (UAVs) within the Virginia Commonwealth University Open Cyber City (OCC) testbed. The study focuses on evaluating real-time indoor positioning performance using the Crazyflie drone platform. High-precision position measurements are obtained using the Vicon motion capture system, enabling analysis of the latency between the drone’s actual position and the system-reported position. In a closed-loop control system, the time difference between the position measurement and the application of the control command is called the system delay. Both stationary (hovering) and trajectory-following experiments are conducted to evaluate system performance. Communication delays in …

Examining Mental Healthcare Underutilization Among Latino Immigrants: Healthcare Providers’ And Community Health Workers' Perspectives, Geovani Muñoz

Theses and Dissertations

Latinos continue to experience many logistical and systemic barriers to professional mental health services (Derr, 2016) despite being the second-largest racial-ethnic group in the United States (U.S.). With a community of 65 million people (U.S. Census Bureau, 2024), Latinos experience mental healthcare inequalities (Cook et al., 2019) due to structural, cultural, and systemic barriers. Although prior research has emphasized culturally responsive care as a pathway to reducing disparities (Nagy et al., 2025), much of the literature has focused on Western medical models, with limited attention to community-based perspective. Guided by the Knowledge, Attitude, and Practices (KAP) framework, the present study …

Plumbed 3-Manifolds And Neumann Moves, Noah J. Pope

Theses and Dissertations

We give a constructive proof that every weakly negative definite plumbing tree can be transformed into a negative definite one by a finite sequence of Neumann moves. The argument combines Neumann’s plumbing calculus with the diagonalization algorithm of Duchon, Eisenbud, and Neumann, which extracts the eigenvalues of the framing matrix directly from the combinatorics of the tree. We show that any positive eigenvalues are supported on linear branches and can be eliminated systematically via controlled applications of Neumann moves. This provides an explicit algorithm reducing weakly negative definite plumbing trees to negative definite ones.

The Transition From School To Work For Students With Emotional And Behavioral Disorders: Examining The Lived Experiences Of Students In Private Day Schools, Gabrielle S. Pickover

Theses and Dissertations

This qualitative phenomenological study examined the lived experiences of young adults with Emotional and Behavioral Disorders (EBD) as they transitioned from private day school settings into sustained employment. Guided by Schlossberg’s Transition Theory, the study explored participants’ perceptions of the barriers, supports, and strategies that shaped their transition experiences. Data were collected through twelve semi-structured interviews with six participants who maintained at least one year of continuous employment following high school. Analysis revealed four primary themes: structure as a stabilizing force, resilience developed through adversity, experiential learning as a pathway to employment, and employment as identity and independence. Findings suggest …

Awareness, Empathy, Action: How American Students’ Study Abroad Experiences In The Middle East And North Africa (Mena) Influence Self-Perceptions Of Global Citizenship, Renee Lamb

Theses and Dissertations

Internationally minded practitioners and academics have posited for decades that global citizenship could be a tool the world can use to build a stronger and more sustainably minded global culture. Through global citizenship’s inclusion in the United Nations Sustainable Development Goals, Target 4: Quality Education, educators from pre-primary to university have been put at the forefront of this movement. At the higher education level, study abroad is arguably the most important global learning tool used by American institutions today for building global citizenship. However, the vast majority of American students study abroad in Western Europe, leaving a glaring gap in …

Comorbid Psychosis In The General Population, Mariam Sankoh

Theses and Dissertations

Psychosis is a complex psychiatric phenotype characterized by substantial heterogeneity in symptom presentation, psychosis diagnosis, comorbidity patterns, and genetic architecture across diverse populations in the general population. Despite advances in psychiatric epidemiology and genomics, important gaps remain in understanding how psychosis symptoms and psychosis-related diagnoses manifest across racial and ethnic groups and how evolutionary genomic factors may contribute to disease risk and cross-ancestry genetic prediction. This dissertation, Characterizing Comorbidity in Psychosis in the General Population, integrates epidemiological, psychometric, and evolutionary genetic approaches to examine psychosis across diverse populations.

Aim 1 examined racial and ethnic differences in psychosis comorbidity patterns …

Cb1 Allosteric Modulation: Preclinical Insights Into Therapeutic Potential And Misuse Liability, Mohammed A. Mustafa

Theses and Dissertations

Cannabinoid type-1 (CB1) allosteric modulators represent a promising approach to modulate CB1 receptor signaling by binding to distinct receptor sites, without producing adverse cannabimimetic and dependence-related effects associated with Δ9-tetrahydrocannabinol (THC) and other CB1 agonists. This dissertation investigates the pharmacological, behavioral, and dependence-related profiles of CB1 allosteric modulators for their therapeutic potential and misuse liability. Presented here, the chiral CB1 positive allosteric modulator (PAM) ZCZ011 was resolved into its R- and S-enantiomers and characterized across in vitro and in vivo assays. Both enantiomers enhance CB1 agonist activity and produce intrinsic effects in vitro. Behaviorally, they produce antinociceptive effects in the …

Munajat: Design As A Dialogue With The Divine, Shawky Abdalla

Theses and Dissertations

Contemporary design discourse remains grounded in functional, seemingly user-centered paradigms, often neglecting what lies beyond the tangible within a human experience. This research challenges such frameworks by positioning design as a dialogue with what exceeds the physical, moving toward the experiential, where meaning precedes and informs form. Drawing on Islamic philosophy, particularly the relationship between zahir and batin (outward form and inward meaning), the study repositions design as a medium for remembrance (dhikr) rather than mere utility.

Through a critique of modernist and postmodernist principles, the research proposes a series of objects that engage with memory, introspection, and transcendence in …

Algorhythm: Commodification Of Hobbies On Social Media Platforms, Fariha Ahmed

Theses and Dissertations

Forcing the world online, the COVID-19 pandemic appeared to turn social-media-based hobbies into income-generating cash cows. Digital creative spaces became sites of capitalist logic where hobbyists came to operate as both laborers and commodities. Profit-focused algorithms operate imperceptibly, shaping creative behavior and decision-making in ways that are difficult to recognize, and even harder to resist. This thesis asks how algorithmic participation on platforms such as Instagram conditions a hobbyist, and how that conditioning can be made legible to audiences who inhabit such platforms without always seeing them. Using autoethnography, I position myself as both researcher and subject to document the …

From Cultural Binaries To Coexistence: A Graphic Autoethnography Of Individualism And Collectivism In An International Context, Shahad Alsubaie

Theses and Dissertations

This arts-based autoethnographic study investigates individualism and collectivism, specifically through my study-abroad experience traveling from Saudi Arabia to the United States. Through arts-based reflective practice, I depicted the diasporic experience of being ontoepistemologically collectivistic while navigating a primarily individualistic society. I use the medium of a graphic memoir to illustrate and develop frameworks of confluence that embrace the two distinct cultural orientations simultaneously. This arts-based self-study not only contributes to the body of transnational scholarship but also serves as a reference for international students, researchers, and educators to use arts-based subgenres and data analysis methods to gain better insights into …

The Weight, Hammet Reavis

Theses and Dissertations

What follows drifts between out to under, argument to object, learned to unlearned, and then back again, for now. What remains is not erased, but held in tension - pressed forward by an unspoken weight. However, let's go on record and retrace this gesture, not by means of crossthru, but as underline.

Will You Let Me In?, Irene Piazza

Theses and Dissertations

Imposed borders are everywhere: The borders created by stanchions during bureaucratic lines, the borders of a country, the borders of a page. Humans are forced to follow them. Borders are imposed structures that dictate a way to move, a way to write, a way to be confined. But what happens when those borders aren’t followed? What happens when someone decides to walk through the stanchion belt by crouching under it or sliding its buckle open? What happens if a person decides to walk outside of the paved pathway? What happens if someone crosses a border or writes beyond the page …

Tried For A Flower And Made The Sun, Megan Koeppel

Theses and Dissertations

My thesis work celebrates natural color, honors traditional hand processes, and gently questions the often gendered divisions between different material disciplines. I emphasize the continued relevance of these ancient tacit traditions through exposed seams and stitches. I create a color palette entirely derived from plants and insects, sharing the many shades that come from natural dyes. I create wall mounted and installation based works that soften the edge of distinction between painting, sculpture and textile.

My research includes the history of soft sculpture and American quilting, paired with the stories and chemistry of natural color. With a process closely related …
