Human-Centered Governance Of Climate Resilience: Integrating Sustainability, Equity, And Mental Health, Chelcee A. Pangerl

Graduate Studies Theses and Dissertations 2026

This dissertation examines how sustainability and resilience are defined, implemented, and experienced across three levels of climate governance: household perception, community experience, and federal policy. Climate resilience is often evaluated through infrastructure performance, emissions targets, restoration timelines, and preparedness systems, yet these measures do not fully capture how residents experience uncertainty, support, equity, and mental health. To address this gap, the dissertation develops and applies the Integrated Policy Framework for Sustainability and Resilience (IPFSR). IPFSR organizes six domains into three functional categories: policy outcomes, human-centered dimensions, and implementation mechanisms. Sustainability and operational/physical resilience are treated as policy outcomes; mental health …

Cracking The Code Of Ai Autonomy: Examining The Role Of Challenge And Hindrance Appraisals And Ai Literacy In Task Satisfaction, Rujuta Parekar

Graduate Studies Theses and Dissertations 2026

AI is constantly evolving and being rapidly integrated into the workplace. Limited research has examined how this integration is affecting employee outcomes, and particularly the impacts of whether employees are expected or mandated to use AI for their work. The present study utilized the challenge-hindrance framework to examine the effect of autonomy in using AI on task satisfaction through challenge and hindrance appraisal among working adults. Since the ability to understand and use AI can influence how individuals perceive it, the moderating effect of AI literacy on the hypothesized research model is also examined. A multi-wave research design was used …

Discrete Element Modeling Of Granular Soils: Critical State Behavior Applied To Impact Pile Driving, Esteban Patino Marin

Graduate Studies Theses and Dissertations 2026

This thesis investigates the use of the Discrete Element Method (DEM) to study two complementary aspects of granular soil mechanics: critical state behavior of granular materials and dynamic response of driven piles in sand, both of which are governed by the same particle-scale mechanisms of dilation, contraction, and fabric evolution.

The first examines the critical state behavior and fabric anisotropy of granular soils through DEM simulations of direct shear, direct simple shear, and true triaxial tests. Sphere-cluster particles representative of a uniform sand are used in two assemblages of approximately twenty-five thousand and one hundred twenty-five thousand spheres to evaluate …

Perspectives Of Poetry: Peering Into Poetry And Aphasia, Kristian M. Perez

Graduate Studies Theses and Dissertations 2026

People with aphasia often experience significant barriers to communication, emotional expression, and participation in meaningful life activities following stroke or neurological injury. Although poetry and creative expression have been explored in broader therapeutic contexts, limited research has examined how people with aphasia perceive poetry. The purpose of this qualitative study was to explore the perspectives of people with aphasia regarding definitions of poetry, level of interest in poetry and the factors influencing said interest. Semi-structured interviews were conducted with adults with aphasia recruited through convenience sampling. Participants responded to questions before and after exposure to the poem Trust by Mark …

Securing The Energy Transition: Cyber-Physical Security And Resilience In Next-Generation Power Systems, Airin Rahman

Graduate Studies Theses and Dissertations 2026

Modern power systems are rapidly evolving into renewable-dominated and digitally interconnected cyber-physical infrastructures due to the increasing deployment of distributed energy resources (DERs), inverter-based technologies, and advanced control platforms. Maintaining reliability under high renewable penetration requires flexible resources capable of shifting energy across extended time horizons. Long-duration energy storage (LDES), particularly hydrogen-based energy systems, has therefore emerged as an important enabler of renewable integration, grid flexibility, and resilience. However, the growing dependence on communication, sensing, and distributed control also expands the cyber-physical attack surface of modern power systems, creating security and resilience challenges that conventional operational paradigms were not designed …

Advancing Cyber-Physical Security And Resilience Of Modern Power Systems: Intelligent Monitoring, Secure Operation, And Resilient Recovery, Md Moshiur Rahman

Graduate Studies Theses and Dissertations 2026

Modern power distribution systems are rapidly evolving into cyber-physical, DER-rich, and data-driven networks that rely on extensive sensing, communication, automation, grid-edge intelligence, and operator decision support. While this transformation improves flexibility, observability and controllability, it also expands the cyber-attack surface and increases the risk that cyber intrusions can propagate into physical disturbances, compromised DER operation, degraded situational awareness, and interrupted service continuity. This dissertation advances the cyber-physical security and resilience of modern distribution systems by developing a high-fidelity real-time cyber-physical hardware-in-the-loop testbed using OPAL-RT, EXata CPS, industrial relays, SCADA/RTAC, HMI, and grid-edge devices to emulate realistic DER-integrated distribution grid operation. …

Two-Phase Transcritical Carbon Dioxide Flow At The Microscale For Thermal Management Applications, Soroush Niazi

Graduate Studies Theses and Dissertations 2026

High-power electronic and power-conversion devices now generate heat fluxes that exceed what conventional air- and single-phase-liquid cooling can dissipate, motivating the search for more capable coolants and cooling mechanisms. Carbon dioxide is an attractive candidate for this role: it is inexpensive, non-toxic, and environmentally friendly, and near its critical point its thermophysical properties change rapidly, which raises the heat-transfer coefficient. In addition, a large pressure drop produces strong cooling through the Joule–Thomson effect and phase change, so that the throttling element itself becomes a source of cooling. This dissertation studies the throttling, phase change, and choking of high-pressure carbon dioxide …

Experimental And Computational Characterization Of A Rotorcraft-Tiltrotor Model Using Morphing Wings For Whirl Flutter Instability, Darrell Nieves Lugo

Graduate Studies Theses and Dissertations 2026

Tiltrotor rotorcraft configurations combine the capabilities of vertical and forward flight, offering a crucial and advantageous design for maximizing the operational flight envelope. This versatility enables broad adaptability across numerous designs and platforms, including unmanned aerial vehicles (UAVs), micro-air vehicles (MAVs), and vertical take-off and landing (VTOLs) aircraft. However, propeller-based aircraft are susceptible to an aeroelastic instability at high flight speeds known as whirl flutter. This instability phenomena is a crucial research task and problem to investigate, as with advances in manufacturing and vehicle designs, these can yield new rotorcraft formats capable of advancing the flight envelopes at higher cruise …

Performing Brazilian Identity: The Cultural Politics Of Carmen Miranda, Nicole M. Pineiro Serrano

Honors Undergraduate Theses

This honors undergraduate thesis examines how Carmen Miranda’s performances shaped Brazilian national identity in both Brazilian cinema and Hollywood in the mid-twentieth century. Through film analysis, historical research, and cultural theory, the study examines Miranda’s public persona and the symbolic significance of the Baiana costume, with respect to Brazil’s Estado Novo regime, and Hollywood’s own depictions of Latin America. Overall, it argues that Miranda’s image functioned as a site of cultural negotiation, where Brazilian cultural expression met Hollywood’s exoticizing portrayals, but the encounter did not always stay as a fixed stereotype. The study also examines the tensions between authenticity, commodification, …

Mycoethics: Reverence For Life In Light Of Modern Science, Charis E. Meyers

Honors Undergraduate Theses

There is a 21^st century wave of passion surrounding fungi and mycology, and it’s becoming louder and louder. The mycoenthusiasts themselves have a uniquely inspired ethical system born out of their science, and my aim is to both formally introduce their position, including many unspoken foundations, and defend its potential. I call this position mycoethics and attempt to collect it from the scattered tidbits in mycological media. I first identify its historical precedent, then spend a length of time establishing where its sense of goodness comes from, postulating it as a utilitarian offspring of Albert Schweitzer’s reverence for life. …

Beyond The Square Pulse: Waveform Shape, Eeg Correlates, And The Pursuit Of Natural Sensation In Tens, Jason Whitson

Honors Undergraduate Theses

This study investigates the relationship between electrical stimulus characteristics of shape and charge on evoked sensations and electroencephalogram (EEG) data during multi-waveform transcutaneous electrical nerve stimulation (TENS) of the median nerve. Neuromodulation methods have traditionally had little control over the location and quality of their associated evoked sensation (e.g., electric, vibration, touch). This experiment utilized five unique stimulus waveforms during TENS stimulation. EEG data were collected concurrently to provide an introductory objective measure of the neural responses underlying these sensory changes. Eleven participants completed three tasks (thresholding, super-threshold stimulation, two-alternative forced choice) using a two-electrode TENS approach. Stimulus waveforms were …

Analysis was performed using Direct Analysis in Real Time – High Resolution Mass Spectrometry (DART – HRMS), and extraction efficiency was assessed through spectral correlation with neat reference samples. Results demonstrated that solvent performance was highly dependent …

From Ship To Shore: The Impact Of Sailor Resistance On The Anti-Vietnam War Movement, Trent Chamberlain

Honors Undergraduate Theses

This thesis explores the often-overlooked role of United States Navy personnel in the broader anti-Vietnam War movement. While civilian protests dominate historical narratives of the era, the impact of active-duty sailor resistance remains underexplored. To address this gap, this thesis examines shipboard and shore-based dissent to determine how Naval resistance influenced both military operations and domestic anti-war efforts. By conducting a historical analysis of primary source materials, including military records, underground press publications, and personal accounts, this research traces the evolution of sailor organizing and its intersections with civilian peace movements. The thesis shows that Naval dissent not only posed …

Differing Circulating Microrna Profiles Of Long-Lived Polish Populations, Fabrizzio Lijeron-Herrera

Honors Undergraduate Theses

Exceptional longevity, defined as a lower biological age relative to chronological age and maintenance of functional capacity or a slowing of functional decline, is a phenotype most readily observed in centenarians and nonagenarians. These individuals exhibit a phenomenon known as compressed morbidity, spending substantially less time in poor health compared to younger elderly populations, thus representing a unique human model of delayed aging. Circulating microRNAs (miRNAs), potent post-transcriptional regulators of molecular pathways, have emerged as important modulators of aging-related pathways; however, no study has comprehensively profiled miRNAs from serum in long-lived individuals from Central Europe. In particular, Polish populations present …

Recurrence And Co-Occurrence Of Enhancer-Promoter Interactions Across Human Samples, Satvik Gunjala

Honors Undergraduate Theses

Experimental mapping of enhancer-promoter interactions (EPIs) is resource-intensive, and current computational prediction methods struggle with intrinsic genomic complexity and reliance on limited training data. To address this bottleneck and provide insights for improved computational methods, this study systematically analyzed chromatin contact datasets to investigate the recurrence and co-occurrence of enhancer-promoter interactions across human samples. Putative interactions were evaluated across two HiChIP datasets comprising 218 total samples and one Hi-C dataset comprising 266 samples to assess recurrence across samples and assess sequencing depth related to unique EPIs. Additionally, a preliminary item-based collaborative filtering recommender model was developed to assess co-occurrence patterns …
