Hybridized-Highway Infrastructures, Will Sutton

2026 Research Poster Competition

This research explores highways and their evolving functions through hybrid programming, from the modern era to the present day. As early as 1916, the federal government began funding state construction of the National Highway System. From this point onward, by design, highways became redundant and homogenized networks of automobile movement, crystallizing their function. Despite this, there are global examples of architecturally utilizing space within, above, or below highway infrastructures that hybridize their function beyond vehicular movement. I am currently studying hybridized-highway infrastructures through a literature review that examines them through the lenses of underutilized space associated with highways, the roles …

Stuck In The Middle?: A Design Project To Support Do Not Qualify (Dnq) And Other Struggling Students At The Elementary Level, Steven T. Hartnett, Kevin M. Parkinson, Whitney M. Wayman

Doctor of Education Capstones

This dissertation in practice is designed to support New Kent County Public Schools, which noticed an increase in students being referred for special education services without a concomitant increase in students being found eligible for such services. Systems mapping revealed a root cause of this discrepancy is that the division lacked a comprehensive intervention plan consistently implemented, and - as a result - some students were referred for special education services not due to the presence of a potential learning disability, but merely for lack of other available options. Using tenets from design thinking and design-based research, the project co-created …

The City of Richmond has experienced an imbalance within the current special event permitting process for the Department of Parks, Recreation, and Community Facilities. Park users are not reporting sizeable events being held within the James River Park System, which has caused concern pertaining to environmental and societal impacts. The current permitting process lacks depth and clarity that could be solved by beginning with expanding park user data. This gap of data is the missing piece for the City to be able to make informed future decisions based on a wide array of stakeholder input and tangible visitor use metrics.

Muzzle-To-Target Distance Determination Based On Lead (Pb) Concentration Of Gunshot Residue (Gsr) Using Icp-Oes, Abry Lloyd

Master of Science in Forensic Science Directed Research Projects

The determination of muzzle-to-target distance remains a significant challenge in forensic casework. Current approaches to gunshot residue (GSR) analysis rely primarily on colorimetric testing to indicate chemical components present and subjective interpretation, limiting specificity and contributing to ongoing scrutiny within the field. This study investigates a quantitative method for estimating shooting distance based on the concentration of lead present in GSR samples (w/w%) with the utilization of inductively coupled plasma optical emission spectrometry (ICP-OES). Test firings were conducted using caliber 22 Long Rifle, 9mm Luger, and 40 S&W semiautomatic handguns at defined distances to evaluate the relationship between lead concentration …

Seeing The Invisible Load: Xr+ Multimodal Sensing For Cognitive Ergonomics In Industrial Training, Jessica M. Johnson, Andwele Grant

Virginia Digital Maritime Center (VDMC) Faculty Publications

Extended reality (XR) technologies are increasingly positioned as disruptive Industry 5.0 tools for human-centric industrial training and intelligent human–system integration. Coupled with multimodal sensing (eye tracking, EEG, HRV, GSR, and other physiological signals), XR environments promise to make otherwise invisible cognitive demands observable, especially for novice trainees entering complex industrial settings. Yet the evidence base is fragmented: (1) there is no quantitative synthesis of the cognitive ergonomics benefits of XR plus sensing; (2) little is known about which XR–sensor configurations yield the strongest effects; (3) prior reviews rarely focus on industrial and manufacturing tasks; (4) multimodal signals are used predominantly …

Neoliberalism In Education: Three Studies On The Intersection Of Neoliberalism, Science Of Reading, And Policy, Candace Bechtold

Theses and Dissertations

This dissertation consists of three linking projects that study the intersection of neoliberal ideology, American education policymaking, and the Science of Reading (SOR). I sought to understand how neoliberal mechanisms like standardization and accountability have shaped past and current education policies in the United States. In the first project, I take an historical approach to conceptualize neoliberal ideology to explain how it is manifested in Standards-Based Accountability (SBA) reform and demonstrate how its implications have progressed over time. In the second project, I focus on one state's SOR policy–the Virginia Literacy Act (VLA)– to conduct a discourse analysis of documents …

Ontological Runtime Monitoring For Mission Engineering, Alexander R. Will

Theses and Dissertations

The advent of the Urban Air Mobility (UAM) concept will bring low-altitude aviation to civilians through passenger and cargo transport. However, the prospective vehicles in UAM studies are predominantly autonomous, raising questions about their efficacy and stability in densely populated urban areas. At the same time, extensive work has been performed to define a new branch of systems engineering that focuses on runtime behavior, synchronization, communication, and task allocation.This field is known as "mission engineering". Mission engineering has been deployed in military scenarios to model human-autonomy cooperation. By applying the concepts from this field to UAM, full systems-of-systems can be …

Substance Use Behaviors And Treatment Engagement In Individuals With Severe Psychopathology With And Without Comorbid Obesity, Rachel M. Madera-Arnold

Theses and Dissertations

Research has found significantly higher rates of both substance use and obesity among individuals with SMI compared to population samples which in turn can lead to worsening health outcomes. Despite this, there is limited research on the co-occurrence of obesity, substance use, and SMI and how these conditions may interact to affect patient outcomes. In addition, there are many gaps in the research regarding the relationship between substance use and body weight, appetite and/or eating behaviors. This study conducted a secondary analysis of the NSDUH 2021 survey that characterized substance use and disorders among individuals who had severe psychopathology, examined …

Connectedness And Help-Seeking Among Veterans: Integrating The Andersen Behavioral Model And The Three-Step Theory Of Suicide, Samuel Ochinang

Theses and Dissertations

Veteran suicide rates remain higher than those of nonveterans, yet many veterans who die by suicide are not engaged in care prior to death. Veteran help-seeking research often focuses on healthcare utilization, overlooking informal sources of support and the decision-making processes that precede service use. Connectedness is a central protective factor in suicide theory but has received limited attention within help-seeking models. This study examined how connectedness influences veterans’ willingness to seek help. Guided by the Andersen Behavioral Model and the Three-Step Theory of Suicide, this secondary analysis used data from the Military Health and Well-Being Project. The analytic sample …

Family- And Cultural-Level Influences For Latine Adolescent Nicotine Use: A Qualitative Study Informing Prevention, Cindy M. Hernandez Castro

Theses and Dissertations

Early tobacco use among Latine adolescents represents a critical public health concern, with 23.8% reporting current use and exceeding rates among other racial/ethnic groups (Birdsey et al., 2023; Gaddy et al., 2022). This early initiation elevates risks for nicotine dependence and related morbidity in adulthood (Tsao et al., 2023). Guided by Structural Ecosystems Theory (Szapocznik & Coatsworth, 1999) and contemporary grounded theory analysis (Braun & Clarke, 2006; Charmaz, 2006; Noble & Mitchell, 2016), this study examined multilevel influences on nicotine-related attitudes among Latine youth, including: (1) familial factors (i.e., parental monitoring, caregiver-youth communication), (2) cultural dynamics (i.e., cultural values and …

What Is School For? Interpreting Purpose And Practice In A Microschool Case Study, Cammie D. Justus-Smith

Theses and Dissertations

This dissertation examines how one microschool interprets and enacts the purposes of schooling through a qualitative case study of Summit School, an Acton Academy affiliate in a mid-sized Southern city. Situated within broader debates about school choice and alternative education, the study explores how Summit’s vision, structures, and participant experiences illuminate enduring tensions in schooling: civic versus economic aims, public good versus private benefit, and innovation versus institutional continuity. Drawing on interviews, focus groups, observations, and school documents, the study treats Summit not as representative of microschools broadly, but as a bounded case through which larger questions about educational purpose …

The Long Shadow Of The Boys In Blue: Civil War Memory & The Evolution Of Veteran Identity In Twentieth Century Pennsylvania, Alexander L. Barbolish

Theses and Dissertations

This thesis presents a case study of the transformation of veteran identity and civic culture in Northeastern Pennsylvania, tracing the profound shifts in the way Americans remembered war, commemorated sacrifice, and defined what it meant to be a veteran, from the turn of the twentieth century to the dawn of World War II. By examining the complex interactions and relationships between three distinct and overlapping generations of veterans—those of the Civil War, the Spanish-American War, and World War I—this study argues that veteran identity was neither static nor monolithic, but was continually renegotiated through commemorative practice, organizational culture, and public …

Mathematical Models With Clinical Applications For Improving Health Outcomes, Helen Harris

Theses and Dissertations

In clinical settings, patients are exposed to many risks and stressors that could result in adverse health outcomes. Here we present mathematical models that seek to address these risks. First, we present a Markov Chain model to investigate the effect of medication reconciliation (MR) completion on patient health outcomes in the intensive care unit. Using this model, we simulate the annual incidence of adverse drug events (ADEs) for three different ADE rates. Based on the simulated results, we conduct a cost-benefit analysis for various levels of compliance to determine the financial implications of increasing MR completion depending on the baseline …

Re-Sense, Nneoma Njoku

Theses and Dissertations

Re-Sense examines artist’s books as perceptual tools capable of reshaping how readers encounter history, memory, and archival absence. Beginning with the idea that books teach us how to know and how to see, the text argues that conventional book structures often reinforce Western knowledge systems through overemphasis of linearity, coherence, and containment. In contrast, artist’s books' experimental structures support novel modes of knowing and relation to ourselves and the world of humans and non-humans. The author describes this process of exhuming perception from Western constraints as re-sensing.

Through re-sensing, the historical past becomes less like a fixed record and more …

A Framework For Digital Energy Modulation And Translation In Projectional X-Ray Imaging, Richard R. Wargo

Theses and Dissertations

In projectional X-ray imaging, acquisition energy fundamentally influences subject contrast, image noise, and radiation dose. While dual-energy techniques exploit spectral differences to optimize contrast and enable material separation, acquiring multiple images of the same anatomy often requires additional exposures and increased system complexity.

This dissertation presents a framework for digital energy modulation (DEM), in which computational models are trained to translate projection images between energy domains without requiring additional X-ray acquisitions. DEM is conceived as a generalizable strategy for controlled contrast modulation in projection imaging, with potential applications in image optimization, radiation therapy alignment, and dual-energy applications.

The framework was …
