Computational Regolith Mechanics And Instrumentation Development For Lunar Exploration And Resource Utilization, Jared M. Long-Fox

Graduate Studies Theses and Dissertations 2026

Sustained exploration of the Moon requires quantitative understanding of lunar regolith properties to support scientific investigation, in situ resource utilization, excavation, and infrastructure development. This dissertation examines the mechanical interaction between robotic excavation systems and lunar regolith, emphasizing how regolith behavior both enables and constrains exploration-focused and exploration-enabled science. Computational excavation models were compared to laboratory data to evaluate prediction of excavation forces and to develop metrics of excavation efficiency. Laboratory experiments using high-fidelity lunar regolith simulants were conducted to characterize pressure-sinkage behavior, shear strength, and angle of repose across a range of material states. Common analytical excavation and terramechanics …

Social Support As An Effect Modifier Of The Assocation Between Drug-Use Related Stigma And History Of Substance Use During Pregnancy Among Women Who Use Unprescribed Opioids In New York City: A Cross-Sectional Study, Isabelle C. Lynch

Graduate Studies Theses and Dissertations 2026

Substance use and misuse among women who are pregnant is a growing public health concern in the United States. Overdose deaths are now a leading cause of death among pregnant and postpartum women, and neonatal abstinence syndrome rates have increased to 23 per 1000 births. A barrier addressing substance use among these women is social stigma, which in part is driven by punitive drug policies that criminalize substance use during pregnancy and societal gender roles and norms surrounding women’s substance use. Social support, including emotional, instrumental, and informational support, can serve to mitigate the negative impacts of stigma on health …

Behavioral Economic Factors Implicated In Young Adult Drinking In The Natural Environment: An Ema Study, Tatiana Magri

Graduate Studies Theses and Dissertations 2026

Background: Young adult (YA) alcohol use remains a prominent public health concern. Despite research efforts aimed at mitigating harms related to drinking, rates of alcohol use and adverse outcomes related to use, remain high among YAs. Previous research has identified alcohol demand, craving, and delay discounting as risk factors for problematic drinking among YAs. However, few studies have concurrently examined these constructs using methodologies that maximize ecological and contextual validity. Method: YA individuals (N=104) completed an ecological momentary assessment (EMA) protocol assessing three demand indices (i.e., intensity, Omax, and breakpoint), delay discounting, craving, and alcohol use and problems. Participants received …

Viral Dynamics Across Managed And Wild Pollinators: Integrating Immunity, Ecology, And Community Structure, Allison Malay

Graduate Studies Theses and Dissertations 2026

Managed honey bees (Apis mellifera) are critical agricultural pollinators, yet colonies continue to experience persistently high losses across North America and Europe. These declines are driven by interacting stressors, including parasites, pathogens, nutrition, and landscape context. Viral pathogens are key contributors to colony morbidity and mortality, but the processes governing variation in viral prevalence, load, and host response remain incompletely understood. This dissertation investigates how viral dynamics in honey bees emerge from interactions among host immunity, colony condition, environmental context, and pollinator community structure. By integrating measures of viral prevalence, viral load, and immune gene expression across multiple …

Exploring The Temporal Dynamics Of Gaming-The-System And Self-Regulated Learning Behaviors Within A Game-Based Learning Environment, Cameron E. Marano

Graduate Studies Theses and Dissertations 2026

Consistently monitoring and regulating cognitive and metacognitive skills during learning is difficult. As a result, game-based learning environments (GBLEs) have been designed to provide richer learning experiences. They foster self-regulated learning (SRL) skills and offer a way to study learners' interactions within complex environments. Although SRL in GBLEs has been widely studied, large gaps remain. For example, it is unclear how improper or maladaptive regulation in GBLEs signals gaming-the-system, in which learners manipulate features to avoid authentic learning. This phenomenon is widely studied in intelligent tutoring systems (ITSs). Limited research has examined how and when both gaming-the-system and SRL behaviors …

Characterization And Experimental Study Of Ammonia-Hydrogen Flames Inside A Toroidal Jet-Stirred Reactor At Atmospheric Conditions, Oli Marquez Valenzuela

Graduate Studies Theses and Dissertations 2026

Due to rising concerns about global surface temperatures and carbon emissions, there has been an increased interest in studying alternative fuels. Ammonia and hydrogen are fuels with the potential to replace general biofuels, hydrocarbons, and sustainable aviation fuels, as they do not contain any carbon, eliminating carbon emissions. However, they are both difficult to work with. Hydrogen has great combustion characteristics such as low ignition energy, high flame speed and lower heating value. However, it is volatile and difficult to store, requiring it to be compressed to high pressure or cooled to incredibly low temperatures. Ammonia can be used as …

Structural Design And Development Of Deployable Propeller Blade, Annan Mashin

Graduate Studies Theses and Dissertations 2026

Aerospace systems frequently face competing requirements between compact packaging and high aerodynamic performance. Large propellers improve efficiency and thrust generation, yet launch constraints and confined storage volumes limit their maximum span. Conventional deployable solutions rely on hinges, locking mechanisms, and external actuation, increasing mechanical complexity and reducing reliability. This dissertation investigates an alternative approach in which elastic instabilities in thin composite shells are deliberately harnessed to enable rapid, mechanism- free deployment of aerodynamic structures. This work harnesses propagating instability in open- section thin-walled airfoil geometries to enable reversible transformation between compact stowed and stiff deployed configurations. By tailoring structural architecture, …

The Revelations, Lily Mckenna

Graduate Studies Theses and Dissertations 2026

The Revelations is a self-actualization in the form of a poetry collection. The speaker’s realization that reality is relative arrives through a Title IX case against an abusive boyfriend and former bandmate. Poems such as “Complainant / Respondent” use rigid legal structures to investigate the fluidity of truth and perception and how they can be manipulated. With her band on hiatus and the case propelling her into a new world, the speaker starts running DIY shows alongside a cast of characters with a shared love of music. She interrogates their realities in the character studies “On The Relative Reality Of…,” …

Temporal Patterns Of Storm Surges: Event-Identification, Clustering, And Count Modeling, Ariadna Martin Oliva

Graduate Studies Theses and Dissertations 2026

Coastal regions face compounding risks when extreme events strike in rapid succession, yet most statistical frameworks treat such events as independent, a simplification that can critically underestimate hazard. This thesis addresses that gap through three interconnected contributions focused on the temporal clustering of storm surges at the global scale. A new automated method is developed to extract independent storm surge events from continuous tide gauge records. By leveraging event correlations and a soft-margin approach that accounts for local variability, the method identifies characteristic event durations across 1,485 global tide gauge stations, revealing the influence of both local site conditions and …

Deceptive Design And Disability: How Dark Patterns Affect Users With Visual Impairments, Konstantin Metz

Graduate Studies Theses and Dissertations 2026

Dark patterns are deceptive interface designs that steer users toward unintended actions, often at financial or privacy cost. This thesis examines how those that are vision impaired are at greater risk of these dark patterns given their visual acuity deficit. We conducted semi structured interviews with nine participants across common contexts including e-commerce checkout, subscription and cancellation flows, software download pages, and mobile permission prompts. The data show recurring exposure to dark patterns such as hidden or de-emphasized fees, pre-selected add-ons, deceptive advertising and fake download buttons along with unequal consent paths, repeated permission nagging, and cancellation friction.

The Role Of Adolescent Attachment In The Relationship Between Trauma And Identity, Ellie Mitova

Graduate Studies Theses and Dissertations 2026

Traumatic experiences have been shown to influence identity development during emerging adulthood, a complex developmental period. However, research examining how trauma interacts with adolescent attachment qualities to shape identity processes remains limited. Previous studies have primarily focused on infant attachment styles and their long-term developmental outcomes, leaving a gap in understanding how attachment qualities developed through relationships with parents and peers during adolescence may influence identity development in emerging adults. Additionally, while traumatic experiences have been associated with maladaptive identity processes such as rumination and identity distress, some research suggests that trauma may also contribute to deeper identity exploration and …

The Intersection Of Abuse, Child Welfare, And The Law For Intimate Partner Violence Survivors: Gender Violence As An Antagonistic Social Force, Julio Montanez

Graduate Studies Theses and Dissertations 2026

Intimate partner violence (IPV)—as gender violence—pits children’s civil rights and women’s civil liberties against each other. To explore this phenomenon, the current work features five (5) studies that aim to understand the systemic consequences of IPV and child maltreatment for victims and survivors of both types of abuse.

• Study 1 is a qualitative-deductive study featuring a directed content analysis of news media pertaining to a trial court case on lethal child maltreatment and IPV.
• Study 2 is a qualitative-inductive study featuring a feminist critical discourse analysis of trial court data on lethal child maltreatment and IPV.

An Investigation Into The Impact Of Open Educational Resources (Oer) On Postsecondary Student Outcomes, Amber Mullens

Graduate Studies Theses and Dissertations 2026

Increasing higher education costs are a concern for policymakers and the American public. In 2024-25, undergraduate students paid on average $1,290 for books and supplies (College Board, 2024). These costs have led policymakers and educators to advocate for the use of open educational resources (OER). OER are teaching and learning materials that are in the public domain or licensed under copyright allowing no cost access, reuse, repurpose, adaptation, and redistribution (UNESCO, 2019, p. 5). While research has demonstrated OER use significantly reduces costs for students, less is known about OER's impact on student academic outcomes. Despite significant research on these …

Revolution In The Age Of Social Media: A Mathematical Model For Information, Dissent, And Stability, Killian Muollo

Graduate Studies Theses and Dissertations 2026

Revolutions, defined by Skocpol as rapid transformations in class, state, and/or social structures, are important world events that can cause civil wars, spark international trends, and result in transitions toward democratic and autocratic regimes alike. They are characterized largely by the mechanism of mass mobilization, which is increasingly facilitated by online networks and digital communication. In this dissertation, we investigate such means and outcomes of revolutions as dynamical systems. We construct three models describing separate but complementary aspects of revolution, beginning at the smallest unit of analysis and then moving outward in scope. First, we construct a graph-based model to …

In art, there lives a gift of transcendence with power to transport the viewer into another realm of thought and imagination beyond the limitations of our physical world. This thesis, Magic in the Margins: A Painter’s Ode to Love, Loss, and Laughter, is an exploration of the ways art can serve as both sanctuary and vessel for storytelling. Satire is used to criticize vices, and subtle humor is my tool to resonate serious content necessary for authentic self-reflection. I am investigating how to use painting as a means to make deeply intimate and visceral connections. Each canvas exploring the innermost, …

Do Emerging Social Media Platforms Shape The Gender Gap In Surveillance Political Knowledge?, Saskia Papsova

Graduate Studies Theses and Dissertations 2026

Abstract

Research shows that men consistently score higher than women on standard political knowledge measures, but as Americans increasingly obtain political information through social media, it is unclear whether different platforms affect this gender gap. This study investigates whether social media platforms shape the gender gap in surveillance political knowledge—knowledge of current political facts and contested claims circulating in the contemporary information environment, and which platforms have the biggest impact. Using data from the ANES 2020 Social Media Study, I estimate weighted OLS regression models testing whether platform-specific usage is associated with surveillance political knowledge and whether these associations differ …

Quantifying The Effects Of Anthropogenic Disturbance On Two Marine Mammal Species With Agent-Based Models, Landon S. Myers

Graduate Studies Theses and Dissertations 2026

This dissertation details the construction and results from two agent-based models (ABMs) that quantify the effects of anthropogenic disturbance on very different marine mammals.  Most would agree the anthropogenic effects on animals are “bad”; the unknown is “how bad.”  Chapter 1 describes the ABM assessing the mortality risk from seagrass loss and the potential loss of a warm water refuge on manatees living in Florida ‘s Indian River Lagoon (IRL).  IRL manatees are at the northern habitat limit and susceptible to hypothermic mortality, and utilize natural and artificial warm water refuges to maintain core temperature.  Combined with reduced seagrass availability, …

This model combines multi-channel quantum defect theory, first-principles ab initio molecular calculations, and vibrational frame transformation to accurately model molecular photoionization and electron impact including vibrational dynamics. The scattering data and transition dipole moments for the molecular systems were calculated using R-matrix method through the UKRMol+ codes. A vibrational frame transformation is then performed and multi-channel quantum defect theory is used to calculate closed …

Come And See: Exploring Complex Dynamics And Abjection Through A Southern Gothic Family Portrait, Lenee N. Peterson

Graduate Studies Theses and Dissertations 2026

“COME AND SEE: Exploring Abject Theory Through a Southern Gothic Family Portrait” examines the artist’s complex familial upbringing through the visual and narrative traditions of Southern Gothic art. Drawing upon abject theory and the cultural references of folk horror and Southern Gothicism, this thesis positions the family portrait where intimacy, trauma, and cultural inheritance collide. The project argues that direct confrontation with abjection can foster recognition, shared experience, and the possibility of collective healing. Grounded in practice-based research, this work functions as a critical and creative response to familial strain shaped by scarcity, social oppression, and emotional precarity. Through a …

Unsupervised Transfer Learning And Its Applications In Human Pose Estimation, Qucheng Peng

Graduate Studies Theses and Dissertations 2026

This dissertation advances unsupervised transfer learning by addressing critical constraints in data privacy, intellectual property protection, and deployment in unseen environments. We propose novel frameworks for three progressively restrictive settings: Black-Box Domain Adaptation (BBDA), Source-Free Domain Adaptation (SFDA), Domain Generalization (DG), and Lifelong Domain Adaptation (LLDA) for 3D human pose estimation (HPE). To address BBDA, where only model outputs are accessible, we introduce RAIN (Regularization on Input and Network). This framework utilizes Phase MixUp for frequency-domain input regularization and Subnetwork Distillation to combat source overfitting.

Extending these privacy-preserving paradigms to spatial tasks, we present the first SFDA framework for HPE. …

Examining Attrition In Rtms For Smoking Cessation: The Roles Of Perceived Research Burden And Delay Discounting, Miranda Proctor

Graduate Studies Theses and Dissertations 2026

This secondary analysis examined predictors of attrition in a randomized clinical trial conducted by Roswell Park Comprehensive Cancer Center evaluating repetitive transcranial magnetic stimulation (rTMS) for cigarette smoking cessation. Smoking cessation reduces cancer risk and mortality and improves mental health outcomes. Although rTMS shows promise for supporting sustained abstinence by targeting neurobiological mechanisms underlying nicotine dependence, participant attrition threatens statistical validity, reduces power, and limits generalizability. Identifying predictors of attrition is therefore critical for optimizing trial design and retention.

Research examining predictors of attrition in smoking cessation trials remains limited. Prior work in other clinical populations suggests that higher perceived …

A Sensory Ecology Of Fear: Moonlight-Mediated Predation Risk And Foraging Behavior In Neotropical Electric Fish, Chiu Lok Poon

Graduate Studies Theses and Dissertations 2026

Animals must forage to acquire energy for survival and reproduction, yet foraging exposes them to predators. This creates a trade-off between energy intake and safety, wherein the perception of predation risk alone can alter activity patterns. Within this trade-off, risk, energetic needs, and sensory adaptations vary, shifting the balance and favoring different foraging strategies. Using Neotropical electric fish as a study system, I investigated how foraging under predation risk is shaped across biological scales, including environmental dynamics, interspecific sensory differences, activity-timing mechanisms, and intraspecific variations. These nocturnal fish emit continuous electric signals to sense their environment, allowing non-invasive monitoring of …

Study Of Compressibility Of Flames In Scramjet Combustors, Anirudh Ranganathan

Graduate Studies Theses and Dissertations 2026

Viable forms of propulsion for practical hypersonic flight are of great interest in modern times, of which supersonic combustion ramjets(scramjets) are a very advantageous option. Compared to ramjets, which are severely limited by increasing total pressure loss and dissociation effects, scramjets offer a much more efficient form of propulsion in the Mach 6 – 8 regime. Despite this, a common and unmitigated issue facing scramjet technology is scramjet unstart.

Prior investigations researching scramjet unstart have elucidated global heat release considerations in relation to total fueling or combustion modes as a result of global heat release . Minimal work has been …

Monitoring Shifts In Estuarine Microbial Communities: A Dna-Metabarcoding Approach, Ashley M. Reaume

Modeling Hazard Perception Learning In Novice Drivers With Autism: A Multimodal Simulation-Based Study, Erik J. Sand

Graduate Studies Theses and Dissertations 2026

Young drivers with autism spectrum disorder (ASD) often demonstrate difficulties with road-surveillance behaviors such as scanning ahead, monitoring mirrors, and identifying emerging hazards. These challenges can increase crash risk, particularly for adolescents with limited driving experience. This study explored whether a simple, video-game–based hazard-training program could improve hazard detection performance, visual scanning, and self-regulation in this population. Five participants aged 15–18 years, each identified by a parent as having ASD and possessing either a learner’s permit or no license, completed sequential Baseline, three Treatment, and Withdrawal phases using the SpeedLimit driving simulation. The study employed a single-case experimental design with …

Source Credibility And Chatbots: How Design Factors Impact Chatbot Effectiveness, Kristen M. Schmidt

Graduate Studies Theses and Dissertations 2026

Source credibility theory states that the more credible a source appears to be, the more likely one is to believe both true and untrue information from it. In the modern day, misinformation is considered a major problem, particularly with virtual communication, meaning it is essential to study what factors influence a system’s source credibility. Virtual agents are a particularly relevant subject of study given that their source credibility can be impacted by both technological and social factors. Across three experiments, this dissertation utilized a novel chatbot interaction design to test how varying design factors would impact a chatbot’s source credibility …

Tl;Dr (Too Long; Didn't Read): Examining The Assessment And Causes Of Careless Responding Within Experimental Vignette Studies, David L. Sexton Jr.

Graduate Studies Theses and Dissertations 2026

Careless responding occurs when participants answer survey items without considering their content and poses a serious threat to data quality. However, while past research has examined its deleterious effects on both survey and low-stakes cognitive ability measures, little research has focused on careless responding in experimental vignette methodology (EVM) research. EVM studies require participants to attend to one or more experimental vignettes, which are carefully crafted written scenarios designed to manipulate a focal variable across conditions. However, if participants are careless in attending to study vignettes, they may not be exposed to the researchers’ intended experimental manipulations, thereby precluding them …

Teoría Y Creatividad. La Literatura Como Herramienta Educativa En El Aprendizaje Moderno De Textos Clásicos En El Idioma Español, Isabel D. Simon

Graduate Studies Theses and Dissertations 2026

In the following master’s thesis, literature is studied as an educational tool in the modern learning of classical texts in the Spanish language from both theoretical and creative perspectives. The theoretical framework to be used is based on the hermeneutic theory of Jean Grondin. The study is divided into three chapters, each focusing on a different literary piece. First, the medieval period is examined through Poema de Mio Cid (Cantar de Mio Cid) of anonymous authorship. In the second chapter, the Golden Age is analyzed through Don Quijote de la Mancha by Miguel de Cervantes. In the closing …
