M. Lim et al., 2023). Artificial Intelligence in Education (AIED) has a history that parallels the development of AI. AIED has shown steady growth and influence in educational programs around the world, with the growth …

Empowered Creation: Investigating Business Acumen And Technological Engagement Among Female Artists As Creative Entrepreneurs, Heggins-Jackson Tracey

Theses and Dissertations

The most powerful vehicle for communication and change is art. Creative endeavors have served humanity as a source of motivation and inspiration, as agents for shaping meaning and, most importantly, evoking empathy. Unfortunately, women in the arts face significant challenges due to deeply entrenched stereotypes, social expectations, societal norms, and gender-related misinformation, which result in destructive narratives. Paradoxically, this marginalized population possesses the skills and insights needed to address disparities through authentic narrative dissemination. Research indicates a limited focus on the contributions and pathways of women in the creative arts industry as entrepreneurs, explicitly highlighting their genuine needs conveyed through …

The Cut Worm Forgives The Plow, August Neuscheler

Theses and Dissertations

The explorations in this thesis writing are centered on William Blake’s proverb “The cut worm forgives the plow.” It has been reinterpreted as an allegory of history and energy. A theory of their relation is proposed based on forgiveness, a theory that accepts the palimpsest of orders as evidence for the abundance of the present moment. The writing focuses on questions of proportionality, scale, archaeological screening methods, planar cutting, and a critique of entropy as grounds for this theory. Some of its subjects include the Statue of Liberty, Kate Raworth’s donut economic model, sashimi, triangulation, Joseph Beuys’ “7,000 Eichen,” semiconductors, …

Dosimetric Validation Of An Electron Monte Carlo (Emc) Algorithm For Small Cutouts And Extended Ssd’S: Assessing Emc In Small Field Dosimetry, Anil Basavaaraju

Theses and Dissertations

This thesis validates the accuracy and limitations of Electron Monte Carlo (eMC) simulations in Eclipse treatment planning systems for small-field electron dosimetry and extended source-to-surface distances (SSDs). Systematic measurements were performed using a microDiamond detector across various electron energies and field sizes. The study examines the discrepancies between measured and calculated (eMC) dose distributions, validating challenges due to lateral scatter disequilibrium and extended air gaps. Our findings provide systematic data for eMC dose calculations and demonstrate that eMC performs within clinical tolerances, with the ultimate goal of enhancing the precision and safety of radiation treatments.

¡Bip Bip! is a body of work that investigates the car as it exists in the American imagination, a metaphorical and physical object where culture, identity, and power intertwine. This work uses painting, printmaking, collage, video, and installation to explore the car as a space of expression, interiority, and understanding the world through a marginalized lens.

Central to my practice is my personal vehicle, Guadalupe, which functions as both muse and metaphor, the main driver of the framework within ¡Bip Bip! My practice examines the different but congruent contexts intersections of this iconic American symbol, the car. In my paintings, …

Beneath The Roots: Becoming Native Through Mangrove Teachings And Wisdom, Shima Aeinehdar

Theses and Dissertations

Beneath the Roots uses the wisdom of mangroves to investigate the naturalization of humans through science, spirituality, and storytelling. The seeds of Avicennia marina, the gray mangrove, drifted to Qatar at some point in history and took root, like so many other people here. The mangrove survives in a harsh saline environment through a unique salt excretion process. As a Qatar-born expat, I relate to this struggle to survive and nativize in a land that is both my own and foreign to me, in a cyclical conversation. I explore this nativization process through a ritual of salt extraction, creating botanical …

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

Theses and Dissertations

Under pressure from mass production and the decline of artisan skills, craft traditions risk becoming relics of the past. Crafting Futures challenges this by treating machines as tools of creative expression, working alongside and in harmony with traditional hand techniques. By pairing an experienced potter with a creatively deployed 3D-printer to develop a series of artifacts, this research fosters a dynamic conversation between partners. Digital fabrication can engage with, rather than replace, traditional making practices, emphasizing the role of the maker’s imagination as the site of knowledge, intuition, and improvisation. The resulting series of hybrid clay vessels reinforce not only …

Theses and Dissertations

As part of the 2025 VCUarts MFA Thesis Exhibition at the Institute of Contemporary Art (ICA) at Virginia Commonwealth University (VCU), I transformed the 'Sponge' gallery on the top floor of The Anderson, VCU’s historic thesis exhibition home, into The Green Room, a neon green, immersive video and performance space featuring mirrors, disco lights, a foam tile dance floor, makeup stations, and a functioning green-screen editing suite. This hybrid drag rehearsal and ‘Chroma-key’ green video production room deepened both my understandings of Queer performance art and process-based art making during the Spring of 2025, through two public performance activation …

Investigating Mitochondrial Stress Response Mechanisms In Aging, Aileigh E. Daniel

Theses and Dissertations

Mitochondrial dysfunction is widely recognized as a key contributor to aging and age-related diseases. The concept of mitohormesis suggests that low levels of ROS can activate stress-responsive transcription factors, promoting adaptive mechanisms that enhance longevity. We hypothesized that changes in protein abundance under conditions of mild mitochondrial stress reflect an adaptive response, and that commonly altered proteins across diverse genetic backgrounds of mitochondrial stress can help identify key regulators of stress resilience and aging. Our study identified conserved mitochondrial stress response pathways and highlighted candidate regulators for further investigation. These regulators appear to impair mitochondrial energy production by downregulating ATP …

Orb Weaver, Quinn Standley

Theses and Dissertations

Orb Weaver is a 24-minute experimental video/lm. This essay does not explain its meaning, as viewers should feel the power to trust their own interpretations. Instead, it reflects on the process of making the lm interwoven with autobiographical thoughts.

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 …

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? …

Hafnium Oxide-Based Nanoheterostructures For Catalytic Radiosensitization And Enhanced X-Ray Radiotherapy, Marlen Dariela Calix Quezada

Theses and Dissertations

Orthovoltage X-ray beams are attractive for surface and intra-operative radiotherapy. Yet, their clinical utility is constrained by rapid attenuation and the limited dose that can be delivered without harming healthy tissue. High-Z hafnium oxide (HfO₂) nanoparticles can boost local energy deposition through the photoelectric effect, while catalytic surface defects accelerate water radiolysis. Harnessing both mechanisms in a single nano-heterostructure could enable potent radiosensitization at diagnostic-range energies.

This thesis develops and evaluates HfO₂-based nanoheterostructures, both bare and Au-decorated, as catalytic radiosensitizers.

Two types of HfO₂ were evaluated, one was synthesized following a specific route and the …

Wander, Wonder: Beyond The Window, Se Young Lee

Theses and Dissertations

This thesis explores how small, site-specific interventions can reframe everyday spaces through acts of observation, walking, and placement. In response to the increasing detachment from physical environments caused by digitized, image-saturated culture, this research asks how gentle gestures might restore presence and embodied perception in overlooked urban sites.

Drawing on the notion of the flâneur and grounded in theories by Peter Zumthor, Rebecca Solnit, and others, walking is employed as a form of spatial inquiry—a way of thinking through movement, of seeing through slowness. Along a recurring route between home and studio, three underappreciated sites were identified and engaged through …

Visible Modulation Of Epsilon Near Zero Materials, Jonathan M. Weber

Theses and Dissertations

While Epsilon-Near-Zero materials have offered many benefits from their introduction to the field of nonlinear optics, those materials have also narrowed the range of wavelengths often studied. With reliable and proven enhancements to light-matter interaction in the ENZ region, many researchers have had little reason to extend the spectrum measured in experiments. The purpose of this work is to measure the intensity dependent refractive index of Indium Tin Oxide across a broad spectral range, from ultraviolet to near infrared, to improve the understanding of semiconductor nonlinearities far from Lorentz and Drude resonances. Furthermore, the visible region is naturally low-loss in …

Plasmon-Assisted On-Chip Integration Of Quantum Emitter For Scalable Quantum Networking, Samprity Saha

Theses and Dissertations

In recent decades, quantum theory has sparked a revolutionary outlook on our long-standing perception of information processing and communication technologies. Photon-based quantum systems, relying on single photons governed by quantum mechanics, hold immense promise for quantum networks due to their resilience against decoherence and fast propagation speeds. However, challenges persist in realizing practical quantum networks, including the need for scalable, robust, and cost-effective quantum light. To address these challenges with classical photonic concepts, this thesis focuses on a plasmon-assisted approach for on-chip integration of single-photon sources. The study aims to develop a scalable solution for integrating quantum emitters on-chip, leveraging …

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 …

Hyperreality Ain’T Really Real: Postmodernity, Social Media, & Blackness, Micah White

Theses and Dissertations

This qualitative study examines the interplay between postmodernity, social media, and African American identity formation through focus group analysis and Grounded Theory methodology. The research investigates how social media’s postmodern features—fragmentation, hyperreality, commodification, and context collapse—shape identity development among African Americans, who historically navigate cultural disruption and systemic racism. Data from semi-structured interviews with two generational focus groups revealed that participants engaged in sophisticated identity curation to balance authenticity and protection in racially charged digital spaces. Key findings highlight the tension between empowerment and marginalization, as social media served as both a platform for racial affirmation and a source of …

A Multimethod Approach To Examining Racial Coping Socialization Among Black Adolescents, Rachel J. Davis

Theses and Dissertations

Experiences of racial discrimination are pervasive in the lives of Black youth and result in race-related stress. Racial coping has been found to mitigate the negative physical and mental health effects of racial discrimination; thus, it is imperative that we understand the process that Black youth undertake to navigate racialized experiences by utilizing a person-centered approach. Additionally, parents socialize their Black youth to navigate racialized experiences, indeed, previous research has investigated racial and emotion socialization as separate phenomena, however, this does not reflect the integrated nature by which racial and emotion socialization processes are interconnected during parents’ and youths’ discussions …

Mental health concerns and the need for mental health resources for high school students continue to rise in Virginia. Some of the reported benefits to the current mental health services and resources offered in Virginia schools are increased academic outcomes, attendance, and positive behaviors. The reported barriers to current mental health services and resources are lack of participation, lack of training, time constraints, funding, and resources. This explanatory sequential mixed methods study examined high school teachers’ perspectives on the benefits and barriers to incorporating mindful artmaking in their classrooms as a mental health resource at a local high school. This …

Using Habituation And Affective Forecasting To Distinguish When The Passive Enjoyment Of Harm Begets The Active Pursuit Of Aggression, Drew M. Parton

Theses and Dissertations

Understanding the antecedents and impellers of aggression is key to preventing violence, and individual differences have been identified as some of the key factors of interest in the study of aggression. Antisocial personality traits such as psychopathy, Machiavellianism, Narcissism, and Sadism have received considerable focus from researchers. Among these traits, Sadism stands above them all as arguably the most malevolent of all trait constructs in psychology. Sadism shows the strongest correlations with aggression among malevolent traits and is uniquely linked to unprovoked aggression, even when it is costly. Sadism thus represents an extreme risk factor for aggression, and studying its …

Facile Synthesis Of Gold, Copper, And Silicon Nanostructures By Laser Ablation In Liquid, Nicholas Simpson

Theses and Dissertations

Metal nanoparticle (NP) synthesis is a continually evolving area of research, owing to the widespread application of NPs in fields such as catalysis, drug delivery, and biosensing. Compared to bulk metal material, NPs contain a larger proportion of surface atoms and exhibit unique optical properties, thus making them ideal for applications where maximizing surface interactions is key. Moreover, their compositions can be altered in several different ways, as evidenced by metal alloy, core/shell, supported, and defective NPs. While conventional synthesis methods are capable of producing NPs in large quantities, they often require conditions of high temperature and pressure, strong reducing …

Dickkopf1(Dkk1): A Novel Endogenous Ligand To Prime Nlrp3 Inflammasome Via Tlr4, Theingi Aung

Theses and Dissertations

Dickkopf1(DKK1) is a quintessential Wnt antagonist and immunomodulator in various inflammatory diseases. The underlying molecular mechanisms of DKK1-mediated immunomodulation remain elusive. Here, we identified TLR4 as a new receptor for DKK1 to activate NFκΒ pathway-mediated gene expression and pyroptosis via NLRP3 inflammasome in human and mouse macrophages.

DKK1 employed TLR4 to initiate NFκB signaling cascade via MyD88. MyD88-TAK1-NFκΒ pathway activation by DKK1 increased HIF1α, NFκB, and NLRP3 protein expression levels, leading to pyroptosis. Unlike LPS, DKK1 did not induce IRAK4 phosphorylation, while the interaction between MyD88 and IRAK4 was maintained for downstream signaling activation. DKK1 did not induce IRF3 phosphorylation …

Beliefs Related To Diagnosing Bpd And Complex Ptsd, Bailey Pascuzzi

Theses and Dissertations

There has been speculation that Borderline personality disorder (BPD) and Complex post-traumatic stress disorder (Complex PTSD) are the same disorder or represent separate disorders on a broader trauma spectrum (Frost et al., 2020; Lewis & Grenyer, 2009). BPD and Complex PTSD share several symptoms but differ in their presentation (Ford & Courtis, 2021). Because the two disorders present so similarly, it could be that clinicians have difficulty differentiating them, leading to misdiagnosis (Miller, 2014). This study examined clinicians’ diagnostic decision-making and stigma toward BPD and Complex PTSD. Participants (N = 426) completed an online survey where they diagnosed a written …

“Some Vague Utopia”: Searching For Urania, Moira L. Neve

Theses and Dissertations

Despite the global pendulum swing of gender trouble marked by the United States’ President’s declaration that there are only two sexes, activists have been rejecting assimilation (ie. defining equality as gay marriage or queer people in the military) within queer studies long before 2025. In the first half of the 20th century, a journal by the name of Urania (1916-1940), privately published and circulated to their home base in the United Kingdom and beyond, five editors (Esther Roper, Eva Gore-Booth, Jessey Wade, Dorothy Cornish, and Irene Clyde/Thomas Baty), challenged the gender binary and the resulting assumptions of heterosexual marriage. This …

Molecular Mechanisms Of Kynurenine-Mediated Lifespan Regulation In Yeast, Ryan E. Counterman Jobb

Theses and Dissertations

The kynurenine pathway is a highly conserved pathway that acts as the primary pathway for tryptophan catabolism and has been found to be involved in lifespan regulation across many diverse organisms. Caloric restriction (CR) is the only known dietary intervention to date that both increases the mean lifespan and the health span of multiple organisms, although the molecular mechanisms of these effects are not fully understood. There are known and sometimes contradictory relationships between the kynurenine pathway activity and the life- extending effect of CR but the crosstalk between the two is not well characterized. Understanding these relationships could lead …
