Pseudo-Boiling Of Supercritical Co2 In A Parallel-Flow Microchannel And A Micro-Jets Impingement Device And Single-Phase And Two-Phase Heat Transfer Of Subcritical Co2 Jets, Pranzal Ahmed

Graduate Studies Theses and Dissertations 2026

Carbon dioxide (CO2) is gaining attention as a low-toxicity, zero-ozone-depletion refrigerant with a global warming potential of 1, making it an attractive alternative to synthetic HFCs/HFOs. Near its critical point, CO2's thermophysical properties change sharply with small shifts in temperature and pressure — a behavior that can be exploited to enhance heat transfer in trans-critical power cycles and electronics cooling. This dissertation experimentally investigates heat transfer during the pseudo-boiling of supercritical CO2 in a parallel-flow microchannel and a micro-jet impingement device, alongside CO2 flow boiling and single-phase water heat transfer in micro-jet impingement. Using microfluidic devices instrumented with embedded resistance …

Learning Weibull Loss Severity Models From Truncated And Censored Data, Majed Alkhasha

Graduate Studies Theses and Dissertations 2026

In modern actuarial science and risk management, due to various loss control mechanisms, observed severity losses are typically left-truncated at the deductible, right-censored at the policy limit, and scaled by a pre-specified co-insurance factor. This results in two types of actuarial payment random variables: payment-per-payment (PPP) and payment-per-loss (PPL). To learn ground-up Weibull loss severity models from PPP and PPL sample data, we implement two estimation techniques: Maximum Likelihood Estimation (MLE) and the dynamic Method of Trimmed Moments (MTM). MLE is employed to obtain efficient estimates of the Weibull shape and scale parameters. However, MLE may assign unnecessarily large point …

Did They Think I Was Rude? The Emotional And Relational Consequences Of (In)Congruence Between Perpetrators’ Self- And Meta-Perceptions Of Workplace Rudeness, Nicholas C. Andriese

Graduate Studies Theses and Dissertations 2026

Workplace rudeness negatively impacts employees and costs organizations millions of dollars each year. Although much is known about the consequences of workplace rudeness, little is known about how perpetrators make sense of and respond to their (potentially) rude behavior. In this dissertation, I propose that perpetrators consider not only their self-perceptions of rudeness, or how rude they believe their actions were, but also their meta-perceptions of rudeness, or their beliefs about how rude another person perceived them to be. Because rudeness is subjective and people vary in their perceptual accuracy, self- and meta-perceptions of rudeness are unlikely to consistently …

Connecting The Existing Fiber Infrastructure To The Future With Antiresonant Hollow Core Fibers, Timothy Bate

Graduate Studies Theses and Dissertations 2026

Optical fiber systems based on solid-core silica waveguides underpin modern telecommunications, high-power laser delivery, precision sensing, and coherent optical systems. However, nonlinear effects, material absorption, and thermal limitations within silica increasingly constrain further scaling in both optical power and transmission performance. Antiresonant hollow-core fibers provide a promising alternative by guiding light predominantly in air, substantially reducing nonlinear interactions, latency, and optical damage while enabling transmission regimes inaccessible to conventional solid-core fibers. Despite rapid advances in antiresonant hollow-core fiber attenuation and power handling, one of the largest remaining barriers to widespread adoption is reliable integration with the existing solid-core fiber ecosystem. …

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 …

Psychometric Evaluation Of The Tattoo Attitudes And Motivations Scale: A New Instrument For Medical Tattoo Consultation, Jeffrey E. Cassisi

Research Data and Datasets

Medical tattooing is increasingly used to restore or alter appearance following surgery, injury, or medical treatment, yet brief instruments for assessing patient attitudes and motivations toward tattooing are limited. This study developed and evaluated the Tattoo Attitudes and Motivations Scale (TAMS), a 10-item measure intended for medical tattoo consultation and research. In Study 1, exploratory factor analysis was conducted with 589 adult women from a general population sample. In Study 2, confirmatory factor analysis was conducted with 261 breast cancer survivors. The final scale supported three factors: Self-Enhancement, Negative Attitudes, and Self-Expression. Model fit was good in the clinical sample, …

Private Money, Public Risk: Why Florida’S Sb 178 Undermines Equity, Ethics, And Accountability In K–12 Athletics, Delante Clark

Graduate Scholarship and Creative Works

This paper critically evaluates Florida Senate Bill 178, which would require the Florida High School Athletic Association to adopt bylaws allowing coaches to use personal funds to support student athletes, once reported and presumed not to be an impermissible benefit. While the bill is framed to help students who lack essential items, it introduces serious structural risks that outweigh its intended benefits. By relying on private contributions within a public educational system, SB 178 threatens equity, transparency, and ethical governance.

The bill encourages uneven financial assistance that varies based on a coach’s personal means and the socioeconomic conditions of individual …

C.A.S. Full Assessment Report: State Of Florida Government Portal, Delante Clark

Graduate Scholarship and Creative Works

The purpose of this assessment is to evaluate the cognitive overhead, transparency, and attentional integrity of

official State of Florida digital interfaces using the Cognitive Attentional Standards (C.A.S.) platform.

While the Florida Digital Bill of Rights (FDBR) establishes strict regulatory guardrails for consumer data

transparency, tracking opt-outs, and attentional safeguards, the State of Florida explicitly exempts its own

government agencies, public universities, and non-profit entities from complying with these rules.

This assessment serves to investigate the tension between legislative intent and government execution. By

analyzing public sector websites through the C.A.S. platform, this project will establish a “state-enforced vs.

state-executed” …

The Attention Safeguard Models: Governing Digital Harm Without Restricting Lawful Speech, Delante Clark

Graduate Scholarship and Creative Works

Digital platforms increasingly govern contemporary social, civic, and psychological life through systems optimized for attention capture, amplification, and monetization. While lawful expression remains protected under the First Amendment, the infrastructural mechanisms that determine how speech circulates have produced a range of attention‑based harms, including cyberbullying, engagement farming, compulsive doom scrolling, emotional dysregulation, and civic polarization. This research paper introduces the Attentional Safeguards Model (ASM), coined and formalized by Delante Clark, as a novel governance framework that mitigates such harms by regulating systems of amplification rather than restricting expression itself. Building on attention economy theory, technological mediation, constitutional free‑speech doctrine, …

The Relationships Among Adverse Childhood Experiences, Medical Usage, And Somatic Symptoms: Stress And Coping As Mediating Factors, Samantha Harper

Honors Undergraduate Theses

It has been estimated that the costs of childhood adversity amount to $14.1 trillion annually (Peterson et al., 2023). Nearly two-thirds of people report adverse childhood experiences (ACEs), including abuse, neglect, or household dysfunction, that reverberate well beyond childhood (Centers for Disease Control and Prevention [CDC], 2023; Felitti et al., 1998). Greater exposure to ACEs is linked consistently to poorer health outcomes, including somatic symptoms or physical symptoms with no organic cause (Katon & Walker, 1998; Sansone et al., 2001; Stuart & Noyes, 1999; Waldinger, 2006). The present study examined the relationships among ACEs, somatic symptoms, and healthcare utilization in …

Impact Of Prostate Cancer Tumor Microenvironment On Alternative Splicing Landscapes In Nk Cells: An Lncap-Based In Vitro Model, Pratham N. Modi

Honors Undergraduate Theses

NK cells play a significant role in anti-tumor activity, yet the transcriptomic mechanisms underlying NK cell dysfunction in the prostate cancer tumor microenvironment remain generally poorly characterized. While most transcriptomic studies focus on gene-level expression, alternative splicing and isoform-level analysis may reveal additional levels of regulation not identified in traditional analysis. The overall goal of this study was to characterize gene and isoform-level changes in NK cells exposed to in vitro prostate cancer conditions and to evaluate whether isoform-level analysis could provide additional depth and insights beyond gene-level analyses. NK92-MI cells were co-cultured with LNCaP prostate cancer cells using direct-contact …

Florida Local Public Administrator Perspectives On Decentralized Wastewater Treatment, Jude Hagan

Honors Undergraduate Theses

Decentralized wastewater treatment (DWT) systems, such as onsite greywater recycling and septic systems, have been demonstrated to be a potentially more sustainable, cost-effective, and disaster-resilient alternative to traditional centralized systems by treating wastewater at or near the source. However, many barriers exist that have prevented the widespread implementation of DWT, such as public opposition, lack of resources, government regulations, public health concerns, and capital costs. In this study, local emergency managers, urban planners, and utility/wastewater managers in Florida were surveyed to determine their perceptions and levels of knowledge on DWT. The results of this study were inconclusive due to a …

Socialization Interventions For Older Adults In Assisted Living Facilities: A Systematic Review, Anoop S. Muvva

Honors Undergraduate Theses

Older adults, defined as individuals over the age of 65, are a growing population in the United States, with projections estimating this group will reach approximately 80 million persons by 2050. Over 90% of older adults are diagnosed with a chronic condition, which can make it difficult to carry out the activities of daily living. As a result, some older adults reside in assisted living facilities, where dedicated staff provide daily support. However, issues in the delivery of care within these settings, including unmet socialization needs and complications among care staff, may contribute to social isolation. Programs designed to address …

Illuminating Those Who Lurk In The Shadows: An Examination Of The Use Of Psychological Profiling In Identifying Violent Criminals In The Modern Age, Skylar R. Holmes

Honors Undergraduate Theses

This study examines the role of psychological profiling in apprehending violent criminals. Psychological profiling involves analyzing behavioral patterns at crime scenes, exploring the relationships between victims, and identifying characteristics and tendencies of offenders. It is currently used by many law enforcement agencies across the country to narrow down a pool of potential suspects and direct researchers, making the most of the limited manpower available. There is, however, a significant limitation in the literature and available evidence that suggests its tenets may be based on intuition and anecdotal evidence purported by investigators, subject to internal bias and thus should not be …

Casual And Confused: Engagement In Non-Committal Sexual Relationships And Its Contributions To Depression And Self-Esteem Struggles Among Young Adults, Sofia A. Marasco

Honors Undergraduate Theses

Non-committal sexual relationships such as hook-ups, friends-with-benefits (FWB/FWBR), and situationships have become increasingly common among young adults and have generated substantial discourse on social media. Despite the rise in modern relationship dynamics and new terminology (i.e., “situationships”), these relationship categories have not been adequately represented in psychological research. The present study examines whether engagement in non-committal relationship types is associated with differences in self-esteem and depressive symptoms compared to committed romantic relationships. Using Bowlby’s Attachment Theory and the Big Five Personality Model, this research also explores whether common interpersonal patterns, attachment styles (anxious and avoidant), and personality traits predict relationship …

An Investigation Of The Impact Of Gender And Race On The Stigmatization Of Borderline Personality Disorder, Joshua Samet

Honors Undergraduate Theses

Stigma surrounding mental health reduces treatment-seeking behaviors and can worsen symptoms. Research on stigma surrounding borderline personality disorder (BPD) has shown that race and gender can impact the nature of the stigma associated with the disorder; however, less is known about the interaction between the two. This study investigated if stigma varies when considering both the race and gender of the stigmatized individual simultaneously. 218 undergraduate students read one of four vignettes describing either a Black male, White male, Black female, or White female, then completed the Attribution Questionnaire-20 (AQ-20) stigma scale. The results indicate that there is a statistically …

Regulation Of The Low-Density Lipoprotein Receptor In A Colon Cancer Cell Line By The Prostasin Serine Protease, Juan Pablo Ruiz

Honors Undergraduate Theses

In the effort to combat hypercholesterolemia and cardiovascular disease, research has turned to studying the effects of serine proteases on the low-density lipoprotein receptor (LDLR), which plays a key role in the diseased states with high LDL levels. Matriptase has been shown to proteolytically shed the extracellular domain (ECD) of the LDLR in the co-translational setting. Prostasin (PRSS8) and matriptase (ST14) are part of a proteolytic activation cascade and it is hypothesized that the coactivation of prostasin and matriptase or a pharmacological perturbation of the steady state could result in LDLR ECD shedding in cells co-expressing the receptor and the …

Perceptions, Expectations, And Attitudes About Adolescent Telepsychiatry Among Indian American Family Caregivers, Udayvir Jalf

Honors Undergraduate Theses

Adolescent mental health concerns have risen sharply in the United States. The COVID-19 pandemic marked a significant turning point in mental health care access, with telehealth having become a central mode of care delivery. With adolescent telehealth, caregiver involvement has shown to improve treatment adherence and outcomes. Little is known, however, about how Indian American caregivers experience and navigate their adolescent’s virtual mental health care. This qualitative study investigated the perceptions, expectations, and attitudes of Indian American family caregivers regarding adolescent telepsychiatry and caregivers’ involvement. In depth semi-structured interviews were conducted with Indian American caregivers of adolescents who completed at …

Comparative Spatial Biology: A Cross-Species Analysis Of Canine Oral Cancers As Models For Human Disease, Ram Pradhyumnan

Honors Undergraduate Theses

Oral squamous cell carcinoma (OSCC), one of the most common malignancies of the oral cavity, remains a clinically challenging disease due to its aggressive behavior, late-stage diagnosis, and limited improvements in therapeutic outcomes over recent decades. A significant barrier to progress in OSCC research and treatment is the lack of suitable preclinical models that recapitulate the complexity and natural progression of the disease. Most current models—including cell lines, xenografts, and genetically engineered mice—fail to capture key features such as the spatial organization of tumor epithelium, interactions with an intact immune system, and the stepwise evolution from normal mucosa to invasive …

Artificial Elections: How Artificial Intelligence Can Affect Elections And Decide Our Future, Ryan D. Granger

Honors Undergraduate Theses

This thesis examines the growing role of artificial intelligence (AI) in democratic elections, highlighting both its transformative potential and its associated risks. Drawing on a qualitative analysis of existing literature, the study explores how AI is increasingly integrated into political campaigns, election administration, and voter engagement. Key benefits include enhanced data analysis, personalized political messaging, and improved efficiency in campaign operations. AI also supports real-time fact-checking and more accurate vote tabulation, which can strengthen transparency and trust in electoral processes. However, the thesis emphasizes that these advantages are accompanied by significant challenges. AI technologies enable the rapid creation and dissemination …

Who Makes The Jury? Demographics And Decision-Making In The Jury Process., Ana B. Pons

Honors Undergraduate Theses

Within the American judicial system, juries have played a central role in promoting representation and fairness in the courtroom. However, limited information exists on whether prosecutorial decisions during jury selection, jury composition, or jury behavior differ based on the sex, race/ethnicity, type of case, political ideology, or geographic location of potential jurors. Following PRISMA guidelines, this scoping review synthesizes 48 peer-reviewed articles published between the 1940s and 2026 to examine whether prosecutorial decision-making and jury outcomes vary based on the sex, race/ethnicity, type of case, political ideology, or geographic location of potential jurors. Findings indicated that men are disproportionately selected …

Invasion Of Microplastics Into The Reproductive Tissues Of Feral And Domestic Felines, Emma K. Quade

Honors Undergraduate Theses

Although plastics have many useful properties in modern society, once these materials are introduced into the environment, they can cause extensive damage. Following degradation into microplastics (MP), plastic particles less than 5 mm in size, these contaminants can make their way into a variety of different environments and organisms. There are many studies that have investigated the prevalence of MP in marine environments, but fewer studies have looked into terrestrial systems, and even less that have focused on contamination in companion animals. This study sought to investigate the invasion of MP into the reproductive tissues of felines, Felis catus, …

The Relationship Between Physical Behaviors, Perceived Stress, Oral Hygiene Awareness, And Periodontal Disease Among College Students, Gustavo Quilula

Honors Undergraduate Theses

Periodontal disease (PD) is a preventable inflammatory disease that targets the supporting tissues that surround teeth. PD is extensively studied among older adults, but there is limited evidence of the prevalence of PD and potential modifiable risk factors among young adults. The purpose of this study is to assess the prevalence and severity of PD among U.S. college students and (2) examine the association between objectively measured physical activity (PA), oral hygiene awareness, perceived stress, and PD symptoms. College students from a large metropolitan university were enrolled in this cross-sectional study. Oral hygiene knowledge, PD symptoms, and perceived stress were …

Eroding Protections: The Decline Of Miranda Rights And Its Impact On Due Process In Contemporary America, Autumn G. Pelfrey

Honors Undergraduate Theses

This thesis examines whether the protections established in Miranda v. Arizona, 384 U.S. 436 (1966), remain robust within contemporary criminal justice practice or have been weakened through doctrinal and practical developments. Miranda warnings were originally designed to mitigate the risk that coercive custodial interrogation would produce compelled or unreliable self-incrimination. Since 1966, however, both judicial interpretation and evolving law-enforcement practices have created a growing gap between Miranda’s formal legal promise and its practical operation in real-world interrogations.

The study evaluates the erosion of Miranda’s protective force through three primary mechanisms. First, doctrinal developments have narrowed Miranda’s scope by redefining …

Industrial And Organizational Psychology Researchers’ Positive And Negative Experiences With The Peer-Review Process, Alexa Weaver

Honors Undergraduate Theses

Peer review plays a critical role in advancing the field of psychology; however, limited empirical research has examined psychologists’ experiences with the peer review process. The present study investigated both positive and negative peer review experiences among industrial and organizational (I/O) psychologists and assessed the prevalence of specific reviewer behaviors. A two-phase survey design was administered via Qualtrics. Study 1 employed open-ended questions to identify recurring themes in researchers’ experiences with peer review. Thematic analysis revealed distinct positive and negative patterns of reviewer behavior, which informed the development of Study 2.

Study 2 quantitatively assessed the prevalence of behaviors associated …

Examining The Barriers To Healthcare Among Native Hawaiian And Pacific Islander Populations Living In Hawaii, Gracie L. Kaye

Honors Undergraduate Theses

The state of Hawaii was annexed by the United States in 1898, and served as a starting point from which the U.S. influenced Hawaii's socioeconomic conditions and healthcare access. The literature review examines healthcare views and outcomes among Native Hawaiian and Pacific Islander residents, utilizing various tools and resources to investigate how these factors have impacted overall health statistics and the reasons behind these trends. Results found that the western colonization of the island and the disease outbreaks led to an initial mistrust of “western ideas.” Additionally, due to long-standing cultural beliefs, there is a natural preference for traditional cultural …

Interaction Of The Dap-10 Fluorescent Light-Up Aptamer With An Environment-Sensitive Dye, Crystal Violet, Marina Tsukanova

Honors Undergraduate Theses

Crystal violet (CV) is an environment-sensitive dye whose fluorescence is strongly influenced by microenvironment polarity and viscosity, increasing markedly when rotational and vibrational motions are restricted. While the fluorescence enhancement of CV by fluorescent light-up aptamers (FLAPs) has been noted in literature, the specific binding interactions between CV and aptamers in the DAP-10 family have remained under-investigated.  The objective of this work is to elucidate the binding site interactions between CV and the DAP-10-42 FLAP. It is hypothesized that positions 34 and 35 of the aptamer’s sequence reside in a proposed quadruplex-duplex junction that form the dye-binding pocket of DAP-10 …

Expanding Assessment Of Adverse Childhood Expereneces(Aces) To Include Childhood Disabilties And Medical Trauma., Cassidy E. Chergi

Honors Undergraduate Theses

Adverse Childhood Experiences (ACEs) are considered a fair predictor of future physical and mental health outcomes. However, historically, the ACEs framework has not fully incorporated chronic stressors associated with childhood physical disabilities and health conditions. This study proposes an expansion of ACEs to include serious childhood medical issues and events as well as disability-related adversity—such as early experiences of functional limitations, social adversity, and system-wide barriers. This study also explores the correlation between these serious medical issues and disability-related adversity in childhood and psychological issues in early adulthood, including signs of trauma, depression, and anxiety. Understanding these relationships can contribute …

How Does The Frequency Of Visits Impact The Quality Of Life For Nursing Home Residents?, Sophie M. Carlton

Honors Undergraduate Theses

This integrative literature review examines the relationship between quantity of visitation and quality of life (QOL) of nursing home residents. The purpose of this review is to examine existing research to determine whether an optimal “dosage” of visitation exists that meaningfully enhances QOL for this vulnerable population. Establishing an evidence based- guideline may help reduce uncertainty for families and promote more consistent improvements in resident well-being. Nursing home residents are the focus of this work because their limited ability to leave the facility makes visitation one of their primary sources of non-occupational social interaction. The COVID19 pandemic further heightened the …
