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 …

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 …

Performing The Digital Identity: A Media Discourse Analysis Of Online Identity Construction, Dalya Qasem

Graduate Studies Theses and Dissertations 2026

This dissertation investigates how news media construct narratives about TikTok and its role in shaping digital identity. While existing scholarship has examined issues such as privacy, marketing, and entertainment, less attention has been given to how identity is represented, negotiated, and understood within public discourse. Using Critical Discourse Analysis (CDA) combined with computational text analysis through Voyant Tools, this study analyzes a corpus of 111 news articles published between 2020 and 2025 that explicitly reference TikTok and identity. The analysis identifies prominent keywords, topics, and rhetorical patterns across media texts. Furthermore, the research demonstrates a critical analysis of popular understandings …

Visual Cues Of Human-Likeness, Not Salience, Impact Trust-Related Human-Computer Interaction, Jordan Schotz

Graduate Studies Theses and Dissertations 2026

As interactions with digital agents become increasingly integrated into daily life, understanding how visual representations influence social decision-making is critical. Previous research in human-computer interaction has frequently confounded the psychological effects of an agent's perceived human-likeness with the underlying visual salience of the stimuli. To address these persistent gaps, the present study systematically isolated the effects of human-likeness and visual cue trustworthiness on trust behavior while controlling for objective image properties. The present study expanded on and normed the Virtual Avatar Facial Stimuli Set (VAFSS), a comprehensive database comprising hundreds of identity-matched photographs and computer-generated avatars varying across a spectrum …

Exploring Barriers And Facilitators Of Mental Health Treatment For Law Enforcement Officers: The Impact Of Police Occupational Culture, April Reed

Graduate Studies Theses and Dissertations 2026

Prior research has explored the impact of police culture on mental health stigma among law enforcement, however, a deeper understanding about how different aspects of police culture may inhibit or facilitate mental health treatment utilization is needed to inform policy and practice. This dissertation explores the relationship between police culture and mental health using a qualitative research design. Twenty-five (n=25) law enforcement officers from a county sheriff’s office in Central Florida were interviewed and participant observations were conducted during a three-month period. The present study sought to address the following research questions: What are the experiences of the job and …

Online Risk And Harm For Marginalized Users: How Social Influence Amplifies Or Mitigates Vulnerability, Tangila Islam Tanni

Graduate Studies Theses and Dissertations 2026

Social media has reshaped how people connect, communicate, and influence one another, yet these environments also create harms that disproportionately affect marginalized users. Participation in online communities can expose users to identity-based harassment, emotional distress, and the normalization of harmful attitudes, shaping identity, well-being, and participation online and offline. Prior work has documented many forms of online harm, yet less is understood about how harmful norms and behaviors are reinforced across different forms of social media interaction, from private direct messages to online communities. Guided by the Social Ecological Model, this dissertation investigates how online harms toward marginalized users emerge …

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′ …

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 …

Restoring Digital Trust: Decentralized Frameworks For Identity, Consent, And Media Provenance, Raghu N. Avula

Graduate Studies Theses and Dissertations 2026

Digital platforms are deeply embedded in modern society through centralized network architectures. As online interactions transition to the physical world handling sensitive data, user privacy and cryptographic security require enhancement beyond traditional limits. This dissertation presents a decentralized “Tri-Layer Trust Architecture” that leverages Verifiable Trust Registries, Cryptographic Binding, and Edge Verification to prioritize data sovereignty and local authentication. To demonstrate the architecture’s applicability across distinct operational environments, we implement three solutions: (1) Verifiable Presence for peer-to-peer ride-sharing via D-RideX, which encrypts biometric data on physical hardware (TEEs) and Soulbound Tokens (SBTs) to prevent impersonation without cloud database exposure; (2) Verifiable …

An Integrated Framework For Last-Mile Delivery Optimization Using Reinforcement Learning And Social Media-Based Traffic Prediction In Underdeveloped Megacities, Vasanth Bhat

Graduate Studies Theses and Dissertations 2026

Supply chain management has become increasingly critical as transportation costs rise and urban delivery systems place additional pressure on already congested networks. Last-mile delivery—the movement of goods from distribution centers to end users—represents the most expensive and operationally complex segment of the logistics process, particularly in underdeveloped megacities characterized by unpredictable traffic, limited infrastructure, and sparse real-time data. This dissertation proposes an integrated framework for optimizing last-mile delivery in such environments by combining social media–based traffic intelligence, machine learning, and deep reinforcement learning. The framework leverages unstructured, real-time data from social media platforms to enhance traffic prediction and incorporates these …

Essays On Politics And Ideology In Asset Management, Madison Borrelli

Graduate Studies Theses and Dissertations 2026

This dissertation examines how political influence and ideology shape the investment and governance decisions of institutional investors. My first essay studies the effects of political interference on public pension plan asset allocation. Plans facing investment restrictions shift away from low-cost traditional assets toward higher-fee, lower-performing alternative assets. While politicians advocating these restrictions receive increased media attention, state economies do not benefit. These findings underscore how political incentives create agency problems that adversely affect investment decisions and outcomes.

The second essay examines whether differences in political ideology between asset managers and investors give rise to conflicts of interest. Mutual fund institutions …

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 …

The Bite Model And Multi-Level Marketing: How Monat Propagates, Lilly D. Cheung

Graduate Studies Theses and Dissertations 2026

This study aims to understand how MONAT Global Corp, a Multi-Level Marketing (MLM) company, utilizes rhetoric that aligns with Steven Hassan’s BITE Model of Authoritarian Control. Hassan is a cult expert and cult survivor whose work primarily explains undue influence and thought control with BITE representing Behavior, Information, Thought, and Emotional control. The MLM MONAT is a haircare brand that operates through a recruitment-and-sales-based hierarchy, in which sellers sign up and work under one another in a layered marketing structure. To meet quotas and maintain ranks, representatives will use rhetorical strategies to recruit new sellers beneath them in their ‘downline’ …

I, Cock-A-Doodle-Do: Reclaiming Masculinity Through Queer Joy And Humorous Self-Exploration, Nelson J. Garcia

Graduate Studies Theses and Dissertations 2026

I examine the contemporary norms of masculinity. My research wrestles with ultimately unresolvable stereotypes and imagery influencing current masculine behavior. I unearth queer potential through the physicality and behavior of the stereotypical “man’s man”. I infuse my own queer identity into my studio practice with an emphasis on humor and joy to subvert traditional models of male performance. This process drives self-exploration that allows me to personally respond, react, be directed, and redirected by the interactions between queerness and masculinity. Masculine and queer representations across various media, such as film, music, and television, historically and continuously inform restrictive cultural norms. …

Contested Air: Politics, Prejudice, And Radio Broadcasting In New York State, 1925-1928, Sebastian Garcia

Graduate Studies Theses and Dissertations 2026

This thesis examines the intersection between radio broadcasting as the "new media" of the 1920s and American political culture of the period, using New York Governor and 1928 Democratic presidential candidate Alfred E. Smith as a case study. Smith entered 1925 as a political lone wolf and left the year as a triumphant victor set to take the presidency. Building on the work of Smithian scholars, this thesis illuminates how Smith’s radio use remained central to this political transformation. Smith found in radio an apt space to bypass Republican opposition and mobilize the body politic through direct engagement, which, in …

In the film, they do this through the creation of pottery. The imperfect, handmade design style of the film …

Two Essays On Geopolitical Risk And Investment Decisions, Jie Hu

Graduate Studies Theses and Dissertations 2026

My first essay studies how global institutional investors adjust cross-country equity allocations in response to rising geopolitical risk. Using quarterly equity holdings of institutional investors over 1997–2023, combined with news-based global and country-specific geopolitical risk indices, I find that following increases in geopolitical risk within a country, foreign institutions actively reduce their allocations in that country and the nearby region. Elevated global geopolitical uncertainty triggers both a flight-to-home response toward domestic equities and a flight-to-safety effect toward U.S. equities. Investor responses are heterogeneous: Institutions with higher geopolitical risk sensitivity respond more aggressively, whereas larger or better-performing hedge funds often maintain …

Benchmarking And Advancing Heterogeneous Data Reasoning With Large Language Models, Yebowen Hu

Graduate Studies Theses and Dissertations 2026

Large language models (LLMs) increasingly face complex real-world tasks requiring complex reasoning over heterogeneous inputs, including text, numbers, and structured data. This dissertation first investigates the capability boundaries of LLMs under such scenarios. Through the MeetingBank and SportsMetrics benchmarks, we show that while LLMs exhibit linguistic fluency, they struggle with factual accuracy, information density, and quantitative cross-referencing in meeting summarization and sports analysis. Using DecipherPref, a pair-wise evaluation framework grounded in the Bradley-Terry-Luce model, we further probe LLMs' inherent preferences for information-rich and lengthy inputs, and we identify critical deficiencies in financial decision-making through DeFine, where models lack precise insight …

Framing Home: Extending Beyond The Threshold, Kaitlin R. Kirsch

Graduate Studies Theses and Dissertations 2026

This thesis body of work inspects the changes in the artist’s relationship to domesticity and their perceived sense of control over the spaces they have called home. By creating and embellishing spaces that subvert the threshold between the physical and psychic, the works stimulate feelings of comfort or discomfort. Installations of found materials, mixed media, and text-based dark humor, come together to account for this artist’s attempt to navigate the tediousness of daily life. The work takes into consideration the intangible rules that infiltrate a household, defining the framework in which a person learns to live within, or adapt to, …

Essays On Network Resilience: Enhancing Network Resilience Through Network Governance Structure, Process, Environment, And Leadership, Hanvit Kim

Graduate Studies Theses and Dissertations 2026

As disasters become more complex, their impacts often cascade across interdependent systems, creating failures that extend beyond any single organization or sector. Because such crises cut across organizational and sectoral boundaries, effective response depends not only on the capacity of individual organizations but also on the resilience of interorganizational networks. Yet despite the growing importance of networked coordination in disaster response, the concept of network resilience remains underdeveloped in the literature, with limited consensus on its definition, measurement, and determinants. This dissertation addresses that gap by systematically examining what network resilience is, how it can be conceptualized and assessed, and …

Investigation Of Bulk And Periodically Stacked X(2) And X(3) Materials Using Mid-Infrared Femtosecond Pulses, Woraprach Kusolthossakul

Graduate Studies Theses and Dissertations 2026

Mid-infrared (MIR) spectral region represents a vital part of the electromagnetic spectrum, offering applications in spectroscopy, biomedicine, and remote sensing. However, there are no direct broadband MIR laser sources. Nonlinear frequency conversion techniques using second-order nonlinear materials, such as optical parametric oscillator (OPO) and intra-pulse difference frequency generator (IDFG), are promising methods for generating a broadband MIR spectrum. To achieve an efficient conversion, the phase matching condition between the interacting waves of the nonlinear process must be satisfied. Quasi-phase matching (QPM) is a special technique that enables efficient nonlinear processes in materials that cannot be conventionally phase matched using birefringence. …

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 …
