Face2cam: A User-To-Webcam Distance Estimation Image Dataset, Yixuan Zhai, Arryn Robbins

Psychology Faculty Publications

Estimating the distance between a user and their device’s camera is important for tasks such as gaze-aware interaction, adaptive interface scaling, and accessibility tools. Specialized depth sensors are effective but rarely available in everyday computing devices; by contrast, webcams are ubiquitous yet lack native distance information. To advance accessible distance-aware computing, we present Face2Cam, an openly available dataset of webcam images annotated with user-to-camera distances. Thirty-six adults were photographed under controlled variation of head orientation, gaze direction, and illumination, yielding 3,240 labeled images spanning distances from 30–80 cm. As a baseline, we trained a convolutional neural network as a lightweight …

Systematic Approaches To Characterizing Vulnerabilities And Enhancing Robustness Of Text And Vision-Language Models, Poojitha Thota

Computer Science and Engineering Dissertations

The proliferation of artificial intelligence (AI) across critical domains, including news summarization, privacy-policy analysis, and medical decision support, has raised growing concerns about the security and robustness of these systems against adversarial manipulation. This dissertation investigates adversarial robustness in generative AI by addressing three key research goals: (1) characterizing adversarial vulnerabilities across generative models, (2) developing systematic defenses to improve the robustness of generative models, and (3) designing deployment-time safeguards for securing LLM interactions.

Towards the first goal, we characterize adversarial vulnerabilities across text-based and multimodal systems. In abstractive text summarization, we show that inference-time perturbations can exploit lead bias …

Integrated Thermal, Energy, And Structural Performance Assessment Of A Novel In-Service Shallow Geothermal Bridge Deicing System, Alireza Fakhrabadi

Civil Engineering Dissertations

Understanding the performance of bridge deck deicing systems under winter weather conditions is important for improving transportation safety and reducing long-term deterioration of bridge infrastructure. Bridge decks are more vulnerable to icing than ground-supported pavements because they are exposed to ambient air, wind, and radiation from multiple directions, while they do not receive thermal support from the underlying soil. Conventional deicing methods, especially chloride-based salts, can reduce ice formation in the short term, but repeated application may accelerate reinforcement corrosion, concrete damage, and environmental concerns. Therefore, shallow geothermal energy has been considered as a sustainable alternative for bridge deck deicing …

Experimental evaluations were conducted on two large-scale datasets containing over 400,000 traffic instances, demonstrating that the …

The Suppression Of The Opelousas Massacre Of 1868: The Blackleg Hunt Or “La Chasse A’ La Jambe Noire”, August Malveaux

The Griot - Southern Conference on African American Studies, Inc.

This article examines the suppression of the 1868 Opelousas Massacre—also known as “la chasse à la jambe noire” or the Blackleg Hunt—and situates it within the broader landscape of Reconstruction-era racial violence in Louisiana. Malveaux argues that the massacre was not an isolated riot but a premeditated act of political terrorism designed to eliminate Black electoral participation and reverse Reconstruction gains. Triggered by Black political mobilization and white supremacist resistance, the violence unfolded over several days in September 1868 and resulted in widespread murder, intimidation, and property destruction. The essay challenges the historiographical minimization of the event, emphasizing how organized …

Mapping Coastal Vegetation To Evaluate Salt Marsh Decline From 2016 To 2025 In South Carolina, Usa, Zak Henry Bartholomew

Theses, Dissertations and Capstones

Accelerating sea-level rise and storm surge events pose a substantial threat to salt marsh ecosystems, which provide critical ecosystem services. Classification and mapping of coastal vegetation through remote sensing can identify marsh dieback events and provide spatial context for patterns of marsh vulnerability. We used a multi-sensor approach that incorporated LiDAR data, multispectral imagery, and field-derived cover estimates to classify Spartina alterniflora (smooth cordgrass) dominated marsh types on Marine Corps Recruit Depot Parris Island (MCRDPI), a sea island in South Carolina, USA. In summer 2025, surveys were conducted within marsh classes to collect training and validation data. We used random …

Legal Professional Identity Development: An Exploration Of The Social And Emotional Processes By Which Law Students Transition From Novices To Professionals, David Hall Abney Ii

Theses and Dissertations--Communication

This dissertation seeks to heed the call for expansion of instructional communication research (ICR) beyond the undergraduate classroom and undergraduate learning objectives by exploring older learners and higher-order affective learning objectives. Legal professional identity development (LPID) is a discipline-specific type of higher-order affective learning that is conceptualized as a continuous nonlinear process that begins in law school and extends throughout a lawyer’s career, involving the internalization of the legal profession’s core values and norms and their integration with an evolving identity. Using a pragmatic ICR approach and a mixed-methods design, Phase 1 employed individual interviews and focus groups to investigate …

“We Do Things A Little Different Exactly As You'd Expect Here...": Egocentric Network Structures As Predictors Of Organizational Culture Type, Ray Celeste S. Tanner

Theses and Dissertations--Communication

This dissertation examines organizational culture as an outcome of communication structures by integrating the Competing Values Framework (CVF) with egocentric network analysis. Although CVF is one of the most widely used frameworks for diagnosing organizational culture and predicting organizational effectiveness, prior research has overwhelmingly treated culture as an independent variable. Responding to calls for greater attention to the antecedents of culture, this study reconceptualizes organizational culture as a dependent variable and investigates how individuals’ perceived communication networks predict perceptions of CVF culture types. Using egocentric network data collected from employees across a diverse range of organizations and industries, this study …

Effects Of Desiccation On Invasive Faucet Snail (Bithynia Tentaculata) And Trematode Survival, Elise Marie Jordahl

Graduate Research Theses & Dissertations

Parasitism is one of the most common and diverse life history strategies, yet relatively little is known about the role of parasites as invasive species. Invasive species, which present one of the greatest threats to biodiversity, often need to overcome adverse environmental conditions as they establish and spread in new habitats. Invasive parasites are subject to these same conditions, though the effects may be mediated through their hosts. Here, I use an invasive snail and its trematode parasites to quantify the effects of desiccation on survival to better understand how processes of invasion play out in host-parasite systems. The faucet …

Deterministic Black-Box Context-Free Grammar Inference: Scaling From Small To Big Languages, Mohammad Rifat Arefin

Computer Science and Engineering Dissertations

Context-free grammars are essential for a number of software engineering tasks like program understanding, debugging, and grammar-based testing. However, formal language descriptions (i.e. grammars) are often unavailable, outdated, or inaccessible because parsers are closed-source or cannot be instrumented. Black-box grammar inference addresses this gap using only valid sample programs and parser acceptance decisions. The problem is challenging because finite samples rarely exercise all language features or their combinations, while the inference process cannot inspect the parser’s internal representation of syntax. This dissertation develops deterministic techniques for black-box context-free grammar inference. The first tool, TreeVada introduces the structural assumption that balanced …
