Richmond, Fredericksburg & Potomac Passenger Rail Performance And Ridership Study, Matthew S. Sturgis

Master of Urban and Regional Planning Capstone Projects

This study evaluates how targeted infrastructure and operational improvements could improve speed, reliability, and, by extension, ridership on the Richmond, Fredericksburg, and Potomac Corridor between Richmond Main Street Station and Washington Union Station. Although the corridor carries all 198 weekly Amtrak trains operating in Virginia over some portion, passenger rail remains materially less competitive than automobile travel on I-95 when compared under ideal travel conditions or by mode share. In 2024, the corridor carried 1,046,255 riders and held an estimated rail mode share of 2.4 percent relative to 42,598,057 vehicle trips on comparable I-95 segments. At the same time, average …

U.S. Administrative Law: A Casebook (6th Ed.), Jud Mathews

Faculty Scholarship

The number of administrative law texts is vast. The approach of this one, now in its fifth edition, is simple. It is: (1) to focus on the richest and most canonical cases; (2) to provide more extensive extracts of them than most casebooks; and (3) to keep the notes to a bare minimum. Updated through October 2025, the book contains a number of significant decisions from recent Supreme Court terms, as well as foundational classics that many contemporary casebooks cut, and much in between.

Journal of International Technology and Information Management

Digital piracy is a form of copyright infringement, and challenges persist in addressing it effectively. Accordingly, understanding why people engage in digital piracy is crucial. Although prior studies have examined digital piracy from multiple perspectives, existing studies on the explanatory factors of digital piracy remain fragmented. To address this research gap, this study develops an integrated model that incorporates key theoretical perspectives, neutralization theory, social learning theory, and the theory of planned behavior (TPB), along with key determinants including gender, age, and the technology factor. Rather than conducting a meta-analysis of previous studies, this study adopts a survey-based approach to …

Too Warm To Win Big? Unpacking The Backer Dynamics Behind Female Crowdfunding Success Using A Warmth And Competence Perspective, Dan Liu

Journal of International Technology and Information Management

While crowdfunding is often heralded as a democratized funding avenue that empowers women with higher success rates, this study reveals a more nuanced picture of gender dynamics. The Stereotype Content Model suggests that women are often perceived as warmer but less competent. Using a large dataset from Kickstarter, we find that female-led projects can attract more backers, likely due to warmth-driven appeal, but receive smaller average contributions, potentially due to concerns about risk linked to lower perceived competence. However, the total funding raised by female-led campaigns is comparable to that of male-led ones, showing no clear advantage or disadvantage. This …

Values-Based Behavioral Frameworks As Contributors To Organizational Culture In Higher Education: A Literature Review, David J. Park Do

Posters

Colleges and universities almost universally publish statements of institutional values, yet a gap often persists between those stated values and the regularly observed behaviors. This review examines how that gap relates to culture in higher education institutions and specifically explores how translating values into observable behaviors contributes to organizational culture. This literature review used a structured, criteria-guided approach to source identification, selecting sources against three constructs: 1) institutional adoption of values-based behavioral frameworks, 2) organizational culture in higher-education settings, and 3) the perceptions through which organizational members perceive culture. The resulting corpus of 40 sources spans organizational culture scholarship, virtue …

Habitar Lo Vivo, Sara Sánchez-Herrera Cubero

Grado en Diseño de Interiores

The project proposes a Centre for Research into Cognitive Development based on the principles of biophilia, understood as the natural connection between humans and nature. Based on an analysis of the existing building, a rational, modular steel structural system has been developed which contrasts with the organic and sensory dimension of the biophilic design, creating a dialogue between the artificial and the natural. The building is completely hollowed out whilst retaining its structure and façade—as the skeleton and skin of the rationalist movement—and this modular steel structure is incorporated; thanks to its own strength, it can easily create spaces. The …

Comúnia, María Sanjurjo Sánchez

Grado en Diseño de Interiores

COMÚNIA stems from a desire to reinterpret the day center as an extension of everyday life. Moving away from clinical or institutional settings, the project proposes a domestic, warm, and familiar environment—an architectural space that supports individuals with early-stage Alzheimer’s without constantly reminding them of their condition. The design draws inspiration from the interplay between homes and the neighborhood square, viewing these areas as settings for social interaction, autonomy, and shared memories. Each floor represents a different way of experiencing the day: the main floor functions like a town square—a space for socializing and activity; the upper floor offers a …

Efficient And Fair Resource Unit(Ru) Allocation Methods For The Ofdma Mechanism Under Ieee 802.11ax, Yang Yu

Doctoral

The IEEE 802.11ax standard was approved in February 2021. This standard allows users to access different channel bandwidths to transmit their packets under the Orthogonal Frequency Division Multiple Access (OFDMA) mechanism. As the number of Internet users and the number of Internet applications increase, the allocation of channel resources has been a challenge in WLANs. Different types of applications, such as real-time video conferencing, online gaming and large-scale data transfers, generate different requirements in terms of throughput, latency and reliability. Consequently, the diversity in users’ channel bandwidth demands is increasing. Under the OFDMA mechanism, the packets can be allocated into …

The study incorporates a mixed-methods approach and begins with a qualitative theoretical review that includes a thorough literature analysis. A …

Visual Analytics For Interpretable Quantum Computing, Shaolun Ruan

Dissertations and Theses Collection (Open Access)

Quantum computing has entered a stage of increasing practicality. Many quantum hardware vendors such as IBM, Rigetti, Honeywell, and IonQ now enable experiments on real devices in the Noisy Intermediate-Scale Quantum (NISQ) era. These platforms show computational advantages in domains such as optimization, machine learning, and materials science. However, they remain limited by hardware noise and the absence of human-interpretable information. Existing visual metaphors, such as the Bloch Sphere for single-qubit states or circuit schematics for algorithm design, struggle to convey multi-qubit entanglement or measurement probabilities in ways accessible to human reasoning. Likewise, the rise of variational quantum circuits and …

Constrained Reinforcement Learning: From Single-Agent Safety To Multi-Agent Coordination, Hao Jiang

Dissertations and Theses Collection (Open Access)

Real-world decision-making systems such as autonomous driving and largescale ride-pooling must operate under strict safety and resource constraints. Traditional Reinforcement Learning (RL) methods, while powerful in simulation, often fail to guarantee such constraints, limiting their real-world deployment. The fundamental challenge lies in integrating constraint satisfaction with long-term reward optimization, especially when outcomes are stochastic and interdependent across multiple agents.

This dissertation advances the field of Constrained Reinforcement Learning (CRL) from both single-agent safety and multi-agent coordination perspectives. In the single-agent setting, we introduce a Reward Penalty framework that augments the state space with cumulative cost and penalizes only trajectories that …

Improving Pid Control With Bayesian Optimization For Adversarially Robust Federated Learning, Adrian Pena, Sergei Chuprov, Raman Zatsarenko, Leon Reznik

Computer Science Faculty Publications

Federated Learning (FL) often suffers from unstable convergence and reduced robustness under non-IID data and malicious attacks. In this paper, we present FedPIDAvg_tuned, a control-theoretic aggregation framework for improving stability and adversarial robustness in FL. In particular, our approach combines a server-side Proportional–Integral–Derivative (PID) controller with Bayesian optimization to tune controller gains for different data and attack conditions. The PID controller regulates global model updates through feedback on loss dynamics, providing adaptive scaling that improves stability and convergence. The tuned gains are applied within a trust-weighted trimmed-mean mechanism to remove adversarial or outlier updates. Using the Flower framework, we evaluate …

STEMPS Faculty Publications

Educational technologists have not settled on a fixed definition of the field and likely never will. However, attempting to define the field helps to understand the epistemological meanings that shape what the field sees, values, and considers worth pursuing. Through a critical historical review spanning over a century, alongside theoretical engagement with the concepts of entanglement and distributed agency, this paper identifies three key insufficiencies in current educational technology frameworks. These are the persistence of an instrumental-facilitative paradigm that treats technology as a resource deployed by human agents; the theoretical dissolution of the pedagogy-technology dichotomy that existing definitions have not …

Science co-curricular experiences (SciXP)-such as research experiences and internships-are a common, yet understudied, strategy to enhance undergraduates' science career pursuit. Using a doubly robust method to account for initial differences in science motivation, academic readiness, and career intentions, we investigated whether SciXP participation across four years of college predicted undergraduates' (N = 1984) science achievement, career persistence, and motivation at the end of college and after graduation. Participation in science co-curricular experiences was positively associated with science GPA, earning a science degree, being in a more science-intensive career one to two years post-graduation, and viewing science as important and useful …

Nanoparticle Carriers Enhance The Prophylactic Antiviral Effects Of Dsrna In Vitro And Ex Vivo, Shayne Oberhoffner, Stephanie Dewitte-Orr, Starla Richardson, Leah Haile, Dominique Daniels, Erin Cooper, Aizah Ijaz, Janet Velasquez Perez, Mathilde Peruzzi, Bertrand Collet, Paul Craig, Kristof Jenik

Theses and Dissertations (Comprehensive)

Aquaculture now outpaces traditional capture fisheries as the world population and demand for sustainable protein sources increases. Wild and farmed species are increasingly susceptible to pathogen spread as global temperatures rise and stocking densities increase. Despite the devastating losses experienced by aquaculture due to viral infections, there remain few effective prophylactic antiviral therapeutics. Long double-stranded (ds)RNA is a uniquely viral molecule produced by nearly all viruses during their replication cycle, and its detection by salmonids like rainbow trout (Oncorhynchus mykiss) and chinook salmon (Oncorhynchus tshawytsha) leads to the establishment of a defensive antiviral state. Previous in vitro studies demonstrated a …

Science Fiction Cinema And The Technological Sublime: Spectacle And The Infinite From Early Cinema To Digital, David Jackson Dr.

Theses and Dissertations (Comprehensive)

This dissertation examines how science fiction cinema constructs and reimagines the technological sublime in the twentieth century: the experience of awe, terror, and admiration provoked by human-made power and scale. Drawing on the philosophical foundations of the sublime in Edmund Burke and Immanuel Kant and extending through Leo Marx’s and David E. Nye’s theorization of the technological sublime, I propose an aesthetic mode in which representation inflected with affect translates technological spectacle into examinations of humanity’s role and agency in the face of overwhelming technologized worlds and in some cases, even the universe itself.

Through three distinct historical periods …

Implementation Of A 3-Dimensional Hydrodynamic Numerical Model On A Large Northern Lake, Kirin Lorente

Theses and Dissertations (Comprehensive)

Climate change is impacting high latitude regions disproportionately more than those at a lower latitude. With polar lakes being highly sensitive to changes in the climate, shifts in lake ice dynamics and hydrodynamics are indicators of such changes in regional and global climates. These changes impact future seasons in a positive feedback loop, where changes in winter ice cover impact open water nutrients levels and lake thermal structure. This highlights the importance for long-term monitoring. Despite the abundance of lakes distributed across Northern Canada, there has been limited research conducted on these sentinels of climate change.

Specifically, Great Bear Lake …
