Un Lugar A Donde No Puedo Volver: Perteneciendo En La Distancia, Alberto J. Alonso

Graduate Studies Theses and Dissertations 2026

“A Place I Cannot Return To: Distance and Belonging” investigates how home is not limited to a fixed place, but instead a reconstruction sustained through memory and longing, which focuses on personal experiences of being away from Puerto Rico. I contribute to this broader dialogue by offering a deeply personal perspective shaped by the complexities of cultural belonging. Through photography, collage, and painting, my art practice reconstructs fragmented visual narratives of lived experience to explore homesickness, nostalgia, and displacement, examining how personal and shared histories become anchors to what continually slips away. Although I can physically return to Puerto Rico, …

Passenger Pigeons, Dodos, Neanderthals, Jordan Alexander

Passenger Pigeons, Dodos, Neanderthals is a short story collection rooted in Afrofuturism and Southern literature. Passenger Pigeons centers the experiences of queer Black American women in various settings, from Mars to rural Florida. The title story of the collection follows Teri, a human on Mars, attempting to integrate into a society of Martians who exoticize and tokenize her. In this story, I use science fiction as a vehicle to confront the microaggressions and overt racism people of color often experience in professional environments. “Rather Be the Devil,” is a fabulist story detailing the character Man’s journey to find his missing …

Masculine Devotion And Moral Decay: The Paradox Of Chivalry In Malory's Le Morte Darthur, Julia Annunziato

Graduate Studies Theses and Dissertations 2026

This thesis investigates how, within Sir Thomas Malory’s Le Morte Darthur, the concept of chivalry as a literary construct is misunderstood and misrepresented by the knights who attempt to uphold it. Through a close reading of Le Morte, this paper concludes that Malory presents chivalry not as a coherent moral code, but as a paradoxical system that both promotes and undermines the values it claims to uphold. While chivalry is typically meant to emphasize honor, loyalty, and spiritual devotion, Malory’s narrative reveals how these ideals are compromised by structures of masculine competition, performative identity, homosocial desire, and corrupted …

Viral And Host Cell Determinants Of Resistance To Complement-Mediated Killing During Parainfluenza Virus Type 5 Infection, Jenna R. Aquino

Graduate Studies Theses and Dissertations 2026

RNA viruses are a major global public health concern due to high mutation rates, zoonotic potential, and immune evasion. Parainfluenza virus 5 (PIV5) can establish persistent infections (PIs) despite encountering innate immune responses, including the complement (C′) system. RNA virus replication produces defective interfering particles (DIPs) containing truncated defective viral genomes (DVGs) that depend on standard (STD) virus for replication. DVGs are increasingly detected in natural infections and modulate type I interferon (IFN-I), but their role in the C′ system is unclear. We investigated how DVGs affect C′-mediated lysis during PIV5 infection using real-time in vitro cell viability assays. C′ …

Turbine Exhaust Cylinder And Manifold Wake Interactions At High Swirl Angle, Christian A. Anzalotta

Graduate Studies Theses and Dissertations 2026

A commonly observed flow interaction in industrial gas turbine (IGT) exhaust diffuser configurations is investigated, where upstream structural wakes interact with downstream airfoil-like components, potentially leading to unsteady loading. To better understand the mechanisms contributing to this behavior, a scale-model is designed. Dynamic similarity is achieved by matching the Strouhal number (St) of the vortex shedding from the strut. A bell-mouth followed by a swirler is installed in front of the strut to mimic the flow angles at the inlet section of the turbine exhaust. Experiments are conducted for three swirl angles, namely, 30°, 45°, and 60°. Power spectra computed …

First-Principles Insights Into Electronic And Magnetic Structure At Hybrid Interfaces And Low-Dimensional Materials And Reaction On Surfaces, Bushra Ashraf

Graduate Studies Theses and Dissertations 2026

Low-dimensional materials and transition metal surfaces/interfaces provide complementary platforms for understanding how dimensionality, symmetry, spin–orbit coupling (SOC), and interfacial charge transfer/hybridization jointly control electronic structure, emergent magnetism, and surface reactivity. Using first-principles modeling with experimental comparisons, this work aims to establish interfacial structure–property relationships across low-dimensional systems.

Strained Pd adlayers on 2H-MoS₂(0001) provide a controlled platform to separate strain-driven exchange from interface-induced quenching in an itinerant d-electron metal. Although expansive strain promotes magnetism in free-standing Pd, strong Pd–MoS₂ hybridization and charge transfer suppress the monolayer moment and leave a narrow thickness window where magnetism re-emerges in …

The Uncanny And Uneasy: An Exploration Into Using Puppets To Share Dark Stories, Grace Auls

Graduate Studies Theses and Dissertations 2026

In this thesis, I will explore the role of puppetry and practical effects in evoking the uncanny and the uneasy as well as questioning the implications they have in dark theater and cinematic contexts. This paper will examine how puppetry and practical effects can contribute to potentially disturbing and dark imagery both on screen and in live theater. I will be focusing on looking at Jim Henson’s The Dark Crystal, as well as at different puppetry performances used in Voyage of the Little Mermaid (1992), Don’t Hug Me I’m Scared, Kirikou and the Sorceress (Kirikou et la Sorciere), and even …

Rhetoric Of Opportunity: An Analysis Of Gullah Geechee Histories Through The Lens Of Counterstory, Xaria Arthur

Graduate Studies Theses and Dissertations 2026

Counterstory as a method/ology has been used in a variety of disciplines to share experiences of individuals and communities whose voices have been historically silenced or suppressed. Utilizing this methodological framework, my study shares the stories of six Gullah Geechee descendants with ancestral roots in the unincorporated community of Nesmith in Williamsburg County, SC. Treating these minoritized and individual stories as experiential knowledge, I trace the counterstories as topoi to introduce and develop the theoretical concept that I call the rhetoric of opportunity, which refers to memories or stories that have come to motivate individuals toward or away from …

A Test Of The Three-Step Theory: Examining Pain, Hopelessness, And Suicidal Desire Among College Students, Shelby Baker

Graduate Studies Theses and Dissertations 2026

Suicide is a leading cause of death, and suicidal thoughts are prevalent among emerging adults and undergraduate students. Still, many prominent risk factors remain understudied. Guided by the Three-Step Theory of Suicide (3ST), this study examined the roles of hopelessness, psychological pain, and physical pain in prediction of suicidal desire among undergraduate college students (N = 1,705) recruited from UCF’s SONA system and CloudResearch’s Connect platform. Participants completed an online, cross-sectional survey that included measures of suicidal thoughts and behaviors, hopelessness, psychological pain, physical pain, and other psychological variables of interest. Psychological pain and physical pain were tested as moderators …

Investigating Effects Of The Macroalga Caulerpa Prolifera On Restoration Of The Seagrass Halodule Wrightii In The Indian River Lagoon, Florida, Luciana M. Banquero

Graduate Studies Theses and Dissertations 2026

Seagrass restoration efforts have been motivated by global decreases in coverage associated with anthropogenic influences on the environment. In the Indian River Lagoon (IRL), FL, seagrass declined by 75% between 2011 and 2021. During this time, abundance of the macroalga Caulerpa prolifera increased substantially in the IRL. The macroalga is native to this estuary, however C. prolifera abundance has fluctuated widely in the past few decades. Being highly opportunistic, C. prolifera took advantage of areas formerly inhabited by seagrass. It is not known how dense, continuous beds of C. prolifera impact seagrass restoration projects or natural recovery of seagrass. Previous …

Understanding The Potential Biogeochemical Effects Of Alternative Restoration Materials: A Study Of Basalt And Other Materials, Cadie L. Barnes

Graduate Studies Theses and Dissertations 2026

Concern over the effects of microplastics on estuarine ecosystems and public health has prompted many restoration practitioners to switch from plastic materials to more “natural” substrates. These natural (BESE-biopolymer, cement-jute structures) and non-plastic (basalt fiber) materials should not contain harmful substances; however, their chemical composition is unknown. Natural materials may degrade faster in subtropical environments and release nutrients into surrounding waters, which is concerning for eutrophic restoration areas. Basalt fiber bags, made from melted basalt rock spun into fibers, have not been evaluated for biogeochemical impacts within estuaries. To address this knowledge gap, two field experiments and two laboratory experiments …

Establishing And Testing Experiential Critical Theory (Ect), Dolores M. Batten Mrs.

Graduate Studies Theses and Dissertations 2026

There is a current gap in academia which has been largely overlooked in both pedagogy and assessment: the value of personal experience as key evidence of interpretation and meaning-making correlation. Aside from narrative writing, most current methods of literary analysis writing do not place a high value on personal experience beyond the inclusion of brief anecdotes. Yet experience is the major pathway by which an individual forms their worldview, which then informs the ways in which they interpret the world—and by extension, text. This dissertation both establishes and examines the use of Experiential Critical Theory (ECT) in pedagogical application for …

It's All The Same, Lauren A. Bedevia

Graduate Studies Theses and Dissertations 2026

It’s All the Same is a collection of short stories that center around lesbian characters. The stories explore themes such as ambition, morality, karma, mental health, exploitation, and relationships. The collection opens with “Forget Her Inc.,” a short story that juggles an ensemble cast of lesbians and examines whether memory eraser therapy is an ethical practice for treating a broken heart. “It’s All the Same,” the titular story, uses lyricism to present the parallels between two women in terms of family dynamics, interests, and attachment styles; the story explores a loving friendship between a lesbian and a straight woman.

His death sparked outrage, protests, and calls for accountability, justice, and reform. This study addresses the impact of George Floyd’s death as a focusing event that created a policy window under which federal legislation was introduced as a response to his death. Drawing on Punctuated Equilibrium Theory and Social Construction Theory, the study utilizes a critical discourse analysis to test how the death of George Floyd impacted the amount and …

Investigation Of Exotic Phenomena In Topological Quantum Materials, Iftakhar Bin Elius

Graduate Studies Theses and Dissertations 2026

he First Quantum Revolution established quantum mechanics as the foundation of modern physics, enabling transformative technologies such as semiconductors, lasers, and transistors through prin-ciples of quantization, wave-particle duality, and uncertainty. The ongoing Second Quantum Rev-olution harnesses entanglement, superposition, and coherence to advance quantum computation, communication, simulation, and sensing. Central to this endeavor is the study of quantum mate-rials hosting novel electronic structures and emergent phases, including topological insulators and Dirac, Weyl, and nodal-line semimetals. In this thesis, using angle-resolved photoemission spec-troscopy (ARPES), transport measurements, and density functional theory (DFT) calculations, we investigate three classes of materials: (i) magnetic topological semimetals, …

Reframing “Southern Justice”: Public History And The Cultural Legacy Of The Civil War In Orlando, Sarah M. Boye

Graduate Studies Theses and Dissertations 2026

Civil War memory has shaped historical consciousness throughout the American South, sometimes in surprising and unexpected ways. An unusual example of this phenomenon can be found in Orlando, Florida. Unlike in other Southern cities, in Orlando, Civil War memory did not grow out of wartime experience. Instead, it developed decades later during the post-Reconstruction period as generations removed from the war itself constructed their own understanding of the war’s history and its meaning. As the city grew, Greenwood Cemetery became a key site where Civil War remembrance functioned in Orlando. Women’s organizations played a major role in shaping Civil War …

An Algorithmic Framework For Polyhedral Gravity Modeling And Trajectory Propagation Near Small Bodies, Micah S. Boudreau

Graduate Studies Theses and Dissertations 2026

Near-Earth asteroids (NEAs) and other irregular celestial bodies have become increasingly significant targets for scientific investigation and space mission development due to their relevance to resource utilization, origins-of-life studies, planetary defense, and understanding of early solar system formation. As launch costs continue to decline, missions such as NASA’s NEAR Shoemaker, OSIRIS-REx and JAXA’s Hayabusa series demonstrate the expanding feasibility of detailed small body exploration. Despite this growing interest, most standard astrodynamics tools are not designed to model the complex, highly irregular gravitational fields that are a signature of small bodies. Such limitations pose challenges for trajectory design, navigation, and control …

Examining Team Leader Visual Dynamics And Team Performance In Pediatric Emergency Simulations, Annamarie Brosnihan

Graduate Studies Theses and Dissertations 2026

Pediatric medical emergencies are dynamic, high-intensity clinical situations that demand coordinated interdisciplinary actions for optimal patient outcomes. Effective teamwork and leadership are critical, especially during the preparatory phase. Here, team leaders define task goals, assign individual roles, and maintain situational awareness. This phase directs attention, organizes team dynamics, and ensures medical interventions are deployed properly. Medical simulations provide a unique opportunity to capture dynamic leadership behaviors in a controlled low-stakes environment using multimodal data, such as eye tracking, to gain insight into team leader cognitive processes (i.e., attention allocation and information processing). Prior research suggests that leaders who visually attend …

An alarming trend among elementary-aged students in the United States exhibiting significant deficits in social-emotional competency development has intensified since the Covid-19 pandemic. Challenges in developing competent prosocial skills in the elementary-aged years have been associated with difficulties in emotional regulation and social interactions, which can result in compromising school readiness and long-term academic success. Existing school infrastructure provides a vehicle for early intervention, specifically in supporting students with poor social and emotional wellbeing. Thus, the need for innovative pedagogical and instructional approaches that address the complex challenges of the 21st century has become increasingly essential. Coordinated approaches to prosocial …

Making Art For The Love Of The Game, Alissa Beth Burch

Graduate Studies Theses and Dissertations 2026

“Making Art for the Love of the Game” interweaves visual aesthetics from video games and associated online fan community practices with self-portraiture to reflect and process personal past medical trauma, a developmental period in online interactive environments, and showcases self-expressive fan content which joins an underrepresented and emerging sub-culture to contemporary art. Working through an interdisciplinary studio practice, combining printmaking, found-sticker collage, and painting refracts digital aesthetics found in online communities. I intentionally juxtaposed these physical modes of making with digital subjects to examine these subjects’ merit as artistic mediums.  It reflects a contemporary mode of art making, and acts …

Applying Harm Reduction To Binge-Eating Disorder: Protective Behavioral Strategies Against Uncontrolled Eating, Emily Burr

Graduate Studies Theses and Dissertations 2026

Binge-eating disorder (BED) is a highly deleterious mental illness, with ramifications ranging from psychological impairment to premature mortality. Despite the awareness of intervention urgency, treatment strategies to manage BED have limited long-term efficacy. Therefore, it is of high necessity to illuminate other methods of reducing the potential effects of binge eating (BE), either by combatting severity or frequency of the behavior. Protective behavioral strategies (PBS), first identified in the substance use field, are methods by which an individual attenuates potential harm from a behavior without expectation of abstaining (i.e., a harm reduction approach). Given high likelihood of treatment relapse for …

Detonability Limits Of Liquid Fuel Cloud, Khaoula Chougag

Graduate Studies Theses and Dissertations 2026

Detonation-based propulsion systems are of significant interest owing to their high thermodynamic efficiency, rapid energy release, and favorable entropy production relative to deflagration-based systems. Liquid fuels offer practical advantages in storage and volumetric energy density, making them attractive candidates for next-generation detonation engines. This dissertation investigates the detonability characteristics of liquid hydrocarbon fuel clouds through three interconnected studies conducted in a turbulent shock-tube environment using high-speed imaging and pressure diagnostics. The first study maps the detonability limits of monodisperse n-dodecane clouds by systematically varying droplet diameter (5-50 μm) and O₂/N₂ oxidizer composition at equivalence ratios spanning ϕ = 0.8-2.0. Results …

Enhanced Atomization And Combustion In Subsonic Ljic Systems Using Ultrasonically Driven Solid Obstructions, Daniel Sebastian Cruz

Graduate Studies Theses and Dissertations 2026

The liquid fueling methods used in aircraft propulsion have undergone extensive optimization, with Liquid Jets in Crossflow (LJIC) emerging as a simple yet effective injection scheme. LJIC enables sufficient fuel mass flow rates and penetration for high-speed operation, however fuel trajectory and droplet size remain highly sensitive to crossflow conditions. As a result, wide flight envelopes introduce variability in atomization, leading to unsteady combustion performance. Recent work has incorporated a pintile, a solid obstruction placed in the path of the fuel jet, to redistribute momentum and reduce trajectory variability across varying flow conditions. While this approach improves trajectory uniformity, it …

Motivational Interviewing Impact On Provider Burnout, Julie Cook

Graduate Studies Theses and Dissertations 2026

The study of patient–provider communication rarely considers the impact of provider–patient dialogue on providers themselves. This dissertation explores why motivational interviewing (MI) has been shown to reduce burnout among health care providers who use it. Using the empathic communication model (ECM) as a lens, it examines possible explanations for how MI contributes to lower burnout in providers. A mixed‑methods approach was used, consisting of a survey‑based quantitative study and a qualitative study using semi‑structured interviews. The quantitative study surveyed physicians, nurse practitioners, and physician assistants. Participants were asked questions assessing their knowledge of MI, the types of empathy they experience …

Detection And Discrimination Of Targets In Infrared Imagery, Adam T. Cuellar

Graduate Studies Theses and Dissertations 2026

Automated infrared (IR) imagery analysis is essential for persistent surveillance, defense, and security, yet it remains difficult when sensors move and when unknown objects appear. This dissertation addresses two fundamental problems: (1) detecting small moving targets amid platform-motion induced parallax and (2) distinguishing between known stationary targets and out-of-distribution (OOD) objects.   For detecting moving targets while the platform itself is in motion, auxiliary Global Positioning System and Inertial Navigation System data are combined with image analysis. Direction Cosine Matrices from calibrated inertial measurements enable sub-pixel frame alignment unattainable with purely image-based registration. The stabilized sequence is processed by a Reed–Xiaoli …

A Framework For Optimizing Creep Model Parameters From Conventional And Accelerated Creep Tests, William D. Day

Graduate Studies Theses and Dissertations 2026

The demand for efficiency in power generation and propulsion requires higher firing temperatures and reduced cooling air consumption which raises metal temperatures. This makes simplistic creep evaluations, such as Larson-Miller and Orr-Sherby-Dorn parameters, inadequate. Finite element analysis (FEA) must simulate primary and secondary creep, predict failure, and provide design guidance. Gas turbine components, expected to last over 100,000 hours, often require extrapolation of limited test data for new materials. It is essential that robust creep simulations be developed efficiently, accurately, and effectively use limited test data.

This dissertation describes an optimized framework for efficient creep testing and rapid construction of …
