Unsupervised Discovery And Validation Of Affective Engagement States Using Synchronized Eeg And Eye-Tracking During Digital Learning, Menekse Adar

Masters Theses and Doctoral Dissertations

This study explores affective engagement states in digital learning environments using synchronized EEG and eye-tracking data. EEG signals were collected from frontal channels and processed using sliding windows to extract band-power features. Frontal Alpha Asymmetry (FAA; log alpha power difference, F4–F3) and the Beta–Alpha ratio (BA; log beta/alpha power ratio) were used as affective proxies. Instead of predefined emotion labels, unsupervised clustering methods were applied to identify latent engagement patterns directly from EEG features. To ensure robustness, non-overlapping parity analysis and hold-out validation were performed. Statistical tests were conducted to compare FAA and BA values across the identified clusters. Results …

Moral Injury Among Healthcare Chaplains: Responding To Systemic Racism Through Ethical Advocacy And Spiritual Care, Stephanie Drew

Doctor of Ministry Projects and Theses

Systemic racism against minorities has woven its way into every facet of everyday existence, especially for Black Americans, and Healthcare is no exception. There are numerous proven instances of unfair and inequitable treatment of marginalized patients throughout the Healthcare system, and some have even caused Black patients to lose their lives. The mistreatment of Black and Brown people during perhaps one of the most vulnerable times of their lives is well documented dating back centuries. There are massive cuts to Medicaid, and insurance premiums are steadily going up making it very cumbersome for the poor and disenfranchised to navigate the …

Cyanine Dyes As Next-Generation Fluorophores: Applications In Cell Sorting And Fingerprinting Technologies, Super-Multiplexed Spectroscopy, Biomedical Imaging, And Beyond, Lucas Allen Davis

Undergraduate Honors Thesis Collection

As biochemical, pharmaceutical, and medical sciences advance, the demand for technologies capable of probing multiple cellular targets simultaneously continues to increase. Super-multiplexed spectroscopic techniques offer a pathway toward comprehensive cellular fingerprinting by overcoming the spectral limitations of conventional fluorescence labeling. By circumventing the traditional “color barrier,” cyanine-based Raman tags enable the simultaneous discrimination of numerous cellular morphologies, allowing spectroscopy and imaging to be integrated for high-dimensional cellular analysis. Technologies developed in Goda Lab—including high-throughput flow cytometry, virtual freezing fluorescence imaging (VIFFI), Fourier-transform coherent anti-Stokes Raman spectroscopy (FT-CARS), and MERdot nanoparticles—address longstanding trade-offs between throughput, resolution, sensitivity, and multiplexing capacity. Central …

Dis/Remembrance: Expressions Of Intergenerational Memory And Where Legacy Lingers: American Warfare, 50 Years From Saigon, Eli(Se) Davidson

Undergraduate Honors Thesis Collection

Over fifty years from the Fall of Saigon, the United States continues to question its participation in unjust warfare, both as a nation and as a people. This study examines the transmission of war stories amongst families: specifically, what becomes negotiated in the thresholds of memory and narrative, and what might become of those spaces across past, present, and future. While prior discourse has centered on the authority and authenticity of war memory through political discourse, historical narrative, and public memorialization, the role of storytelling within families remains underexplored. This research addresses that gap through interdisciplinary inquiry and qualitative ethnography …

With global temperatures rising, understanding physiological and immunological adaptations to HS is essential for sustainable production. Broiler chickens selectively bred for low water conversion ratio (LWCR) have shown potential for reduced water consumption under environmental challenges; however, their immune resilience under HS conditions compared with modern random-bred (MRB) broilers remains unclear. This study investigated the effects of cyclic HS on red- (RBC) and white- (WBC) blood cells and humoral immunity in LWCR and MRB broilers. Birds were …

Dental Wear In Medieval Hungarian Populations, Sutton Walters

Honors College Theses

Dental wear can reveal past human behavior, offering insight into diet, daily activities and cultural practices (Berbesque et al., 2012; Deter, 2009; Estalrrich & Rosas, 2015; Górka, 2016; Molnar, 2008; Smith, 1984; Watson, 2014). Dental wear can reconstruct past life when other evidence is limited. This paper will address whether dental wear patterns observed in two medieval Hungarian populations, Kiskundorozsma–Kettőshatár I (KK) and SárrétudvariHízóföld (S), reflect sexual dimorphism patterns seen in hunter-gatherer vs. agriculturalist populations. Previous research demonstrates clear differences in wear between high- and lowwear subsistence strategies, whereas other studies report minimal or no sexual dimorphism and little variation …

Personality Meets Possibility: Exploring Cognitive Engagement For Older Adults In A Changing World, Kalvry A. Cooper

All Theses

Engagement in cognitively stimulating activities (CSAs) is critical for maintaining cognitive health in older adults. While existing research has examined the benefits of CSAs, less is known about how factors such as personality traits, education, and technology proficiency influence engagement, especially during the COVID-19 pandemic. This study aims to explore older adults' participation in online versus in-person CSAs during the pandemic and identify key predictors of engagement. Using secondary data from the EFIT and ENACT studies, this research investigates how variables like marital status, education, personality traits, and mobile device proficiency shape older adults' decisions to engage in online or …

Sequence Determinants Of Rna G-Quadruplex Unfolding By Arg-Rich Regions, Naiduwadura Ivon Upekala De Silva, Puspa Kunwar, Md Ibnul Rifat Rahman, Joanna Koryo Kwao, Nathan Lehman, Zihan Zhang, Trenton Paul, Claire Cheng, Nicholas Truex, Hui-Ting Lee, Jun Zhang

Faculty Publications

RNA sequences with the potential to form G-quadruplexes (rGQs) are widespread but largely unfolded in cells by unknown mechanisms. rGQ folding status is a critical regulator of RNA splicing and translation. We show that rGQs can be unfolded by SR proteins, SR-related proteins, and other Arg-rich proteins, including SRSF1, SRSF3, SRSF9, U1-70K, and U2AF1. The length and composition of Arg-rich regions are key determinants of this activity: Arg residues are the primary drivers, while acidic residues attenuate the unfolding activity. To unfold ARPC2 rGQ, at least 13 Arg residues are required. Our findings identify Arg-rich proteins as previously unrecognized, helicase-independent …

Harness: Hybrid Architecture For Resilience In Networked Engineering System Simulations, Daniel Scott

Graduate Theses and Dissertations

This dissertation presents the development of HARNESS, a unified, domain-agnostic framework for the modeling, optimization, and evaluation of complex systems under conditions of degradation and uncertainty. The research addresses a persistent challenge in systems engineering: the lack of a generalizable, behaviorally grounded approach for quantifying resilience and robustness across diverse domains. HARNESS integrates graph-theoretic dependency modeling, GPU-accelerated evolutionary optimization, and agent-based simulation into a modular architecture that enables both system design and diagnostic analysis. The framework models system interdependencies through user-defined components, parameters, and constraints, allowing architectures to evolve dynamically while maintaining structural validity. A mutation-only genetic algorithm with a …

Donor Sex And Platelet Storage Change The Therapeutic Effects Of Platelet-Derived Extracellular Vesicles On Endothelium, Mandeep Kaur, Malvika Gupta, Sowmya Shree Gopal, Charles E Wade, Jessica C Cardenas, Amit K Srivastava

Faculty, Staff and Student Publications

Platelet-derived extracellular vesicles (PEVs) play an active role in vascular protection and repair and are being explored as a viable alternative to platelet therapy. Because platelet function and stability are shaped by donor sex and storage conditions, these same factors are likely to influence the PEVs they release. Understanding these influences is key to developing PEVs into a safe and dependable therapeutic option. In this study, we investigated how donor sex and platelet storage affect the therapeutic properties of PEVs. To address this, PEVs were isolated from platelets of healthy male and female donors. Platelets were either processed immediately after …

"Market Shift Liability" For Generic Drugs: Market Share Theory's Eccentric New Cousin, Lars Noah

UF Law Faculty Publications

Market share liability, which permits allocating proportional responsibility to each tortious member of an industry when victims cannot identify the exact source of their injurious exposure, enjoyed its judicial heyday in the 1980s. It originated in the peculiar setting of litigation over a distinctive cancer that developed decades after in utero exposure to the drug diethylstilbestrol (“DES”), which a few hundred companies had produced and sold for the prevention of miscarriages before federal regulators withdrew it from the marketplace. Although judges have occasionally attempted novel extensions of this theory to other products, and academic commentators remain fascinated by its use, …

Sense Of Belonging And Self-Efficacy Of Women In Stemm At The University Of South Alabama, Emilie Dedeaux

Honors Theses

Despite decades of calls and initiatives to diversify science, technology, engineering, math, and medicine (STEMM) disciplines, females are still more likely to leave STEMM career paths compared to their male peers, which is often depicted as a 'leaky pipeline'. Females in STEMM often report greater social alienation, greater selfdoubt, lower sense of belonging and academic satisfaction due to a mismatch in values in STEMM disciplines. STEMM values have traditionally been normed by cisheteronormative, white, male ideologies . While extensive research has focused on the barriers females experience in STEMM that reduce sense of belonging , less research has focused on …

Compassion In A Warrior Culture: Emotionally Supportive Leadership Among U.S. Military Veterans A Phenomenological Study, Peter Hofmann Phd

Leadership Studies

This qualitative phenomenological study examines how U.S. military veterans with leadership experience describe and make sense of emotionally supportive leadership within the context of a traditionally hierarchical and stoic military culture. Drawing on semi-structured interviews with veterans across service branches, the study explores how participants interpret relational leadership behaviors involving care, responsibility, and responsiveness to others’ suffering, and how these behaviors are shaped, constrained, or legitimized within a warrior-oriented institutional context. Particular attention is given to veterans who self-identify with service-connected conditions, as their experiences illuminate how leadership identity and emotional regulation evolve during and after military service. Participants consistently …
