Fabricating Silver-Ceria Polymer Nanocomposite Scaffolds For Biomedical Therapeutic Applications, Shreya S. Pawar

Honors Undergraduate Theses

Improper healing of bone fractures and limited regeneration of bone following bone tumor resection remain a prevalent complication worldwide. Long-term effects of this include joint instability, limited movement, and arthritis. Bone infections (osteomyelitis), reactive oxygen species (ROS) generation via excessive inflammation, and underlying conditions such as osteoporosis can contribute to suboptimal bone tissue regeneration. ROS accumulation stimulates osteoblast apoptosis, while promoting osteoclast differentiation. These processes inhibit mineralization and osteogenesis. Conventional therapeutics involve the utilization of drugs and bone grafts. However, these approaches pose limitations and can result in subsequent complications. Microbial infections, ROS accumulation, and excessive inflammations are factors that …

Novel Nanomaterial-Based Platforms For Bio-Electrochemical Sensing And Photocatalytic Treatment Of Contaminants Of Emerging Concern In Water, Jonghyun Baik

Graduate Thesis and Dissertation post-2024

This dissertation presents the development of novel nanomaterial-based platforms for bio-electrochemical sensing and photocatalytic treatment of contaminants of emerging concern (CECs) in water, including heavy metals, polycyclic aromatic hydrocarbons (PAHs), per- and polyfluoroalkyl substances (PFAS), and microcystin toxins.

To overcome these limitations, in this dissertation, five distinct platforms were designed, developed, and evaluated under various water conditions.

First, a microbial fuel cell (MFC)-based biosensor was developed for detecting heavy metals (Cu²⁺ and Hg²⁺) and PAHs (benzene and xylene). The system exhibited rapid, linear …

Utilization Of Assessment Results To Improve Identification Of Prenatal Substance Exposure, Whitney R. Mendenhall

Doctor of Psychology (PsyD)

Prenatal substance exposure (PSE) significantly increases the risk of behavioral, emotional, and neurological challenges in children (Eiden et al., 2023). Children with PSE present similarly to children with attention deficit hyperactivity disorder (ADHD) and are often diagnosed with ADHD due to shared symptomatology (Garrison-Desany et al., 2022). However, PSE has a greater association with long-term cognitive, emotional, social, and behavioral deficits (Eiden et al., 2023). While PSE and ADHD share similar symptomologies, treatment and outcomes vary substantially, where early identification and treatment is a critical protective factor against the development of other psychological conditions in children with PSE. PSE can …

Multi-Trait Convergent Evolution Correlated With Host Ecology Suggests Trait Syndromes In Parasitoid Wasps (Hymenoptera: Braconidae)., Christina L. Watkins

Graduate Thesis and Dissertation post-2024

Convergent evolution, the independent evolution of similar traits in different lineages under shared ecological pressures, provides information on patterns of adaptation and character evolution. In Braconidae (Hymenoptera), a diverse and abundant parasitoid wasp family, the assorted biological and ecological traits of their insect hosts have been frequently hypothesized to drive repeated morphological evolution. This study presented the first family-wide phylogenetically informed test of host-driven convergence in Braconidae, integrating morphological and ecological data across 74 genera representing 32 subfamilies on the most current and robust phylogeny. Analyses revealed multiple instances of correlated evolution between host traits and parasitoid morphology, suggesting trait …

An Ailment I Will Fight With: Differential Diagnosis And Methodology Evaluation Of Possible Treponemal Infection At Dayr Al-Barsha, Egypt, Lindsey D. Lefebvre

Graduate Thesis and Dissertation post-2024

Treponemal diseases, including bejel, yaws, pinta, and venereal syphilis, have long plagued human populations and continue to pose public health challenges today. Despite their persistent global presence, the origins, transmission pathways, and archaeological identification of these diseases—caused by various subspecies of Treponema pallidum—remain contested. This study explores the utility of standardized diagnostic criteria, as proposed by Baker et al. (2020), in assessing the presence of treponemal disease in highly fragmentary skeletal remains from the Roman-period necropolis at Dayr al Barsha, Egypt. Through the examination of 14 individuals, this research seeks to (1) identify indicators consistent with bejel (T.p. …

Investigating The Impacts Of Peer Support And Online Information Seeking In Chronic Pain Online Health Communities, Aaron Necaise

Graduate Thesis and Dissertation post-2024

Chronic pain is a highly prevalent medical condition that contributes to intense emotional distress and social isolation in patients. With the growth of social media, online health communities (OHCs) have become a popular resource for patients to learn about their pain and establish social connections with peers. Although there is some evidence suggesting that curated online resources can benefit patient well-being, social media interactions have the potential to propagate medical misinformation and negativity. This dissertation expands upon the Social Communication Model of Pain to examine how interactions within social media-based OHCs impact chronic pain and uncover practical insights into OHC …

Contagion Chronicles: A Spatiotemporal Analysis Of Armed Conflict And Infectious Disease, Devyn Escalanti

Graduate Thesis and Dissertation post-2024

This dissertation examines the relationship between armed conflict and infectious disease transmission through a novel theoretical framework that integrates ecological disturbance and health systems resilience theories into epidemiological contexts. The framework conceptualizes diseases along a continuum from "pulse" to "press." Pulse diseases, like Ebola, are characterized by sudden onset, high mortality, and short-term outbreaks. Press diseases, like HIV, progress gradually with lower mortality and long-term persistence. Grounded in this pulse–press disease typology and ecological and health systems resilience, the theory suggests that the absorptive capacity, adaptive capacity, and resilience of community health workers in conflict areas can influence disease transmission, …

Gait Kinematics And Muscular Responses To Rhythmic Perturbations In Healthy Young Adults, Kayley A. Romero

Graduate Thesis and Dissertation post-2024

Falls pose a significant risk across all ages, leading to injury and loss of independence. Understanding gait adaptation to external perturbations provides insights into balance control and muscle activation, with implications for rehabilitation and fall prevention. While entrainment, the synchronization of biological rhythms to external stimuli, has been widely studied using auditory and visual cues, its effects in response to mechanical perturbations remain unclear. This study examines how young, healthy adults adapt to discrete mediolateral perturbations and whether entrainment occurs when mediolateral perturbations are applied at set timings determined by their natural stride period.

Shock Tube Droplet Breakup Experiments Facilitated By Acoustic Levitation, Anthony J. Aguilera

Graduate Thesis and Dissertation post-2024

Droplet introduction methodology in a shock tube differs based on the experimental conditions. For experiments in which the objective is to image droplet breakup, acoustic levitation allows for a consistent droplet shape and for diagnostic equipment to be aligned to a droplet prior to an experiment. A levitator was designed and used in the University of Central Florida’s shock tube facility. Polystyrene doped droplets were levitated to increase the likelihood of cavitation occurring. Multiple droplets were impacted by a shock wave, and the breakup regime was captured using a high-speed camera.

Paleoethnobotany And Starch Grain Residue Analysis Collected From Ceramics At The White Marl Site, Jamaica, Lydia E. Kiernicki

Graduate Thesis and Dissertation post-2024

The White Marl site represents the largest known Taíno settlement and archaeological site in Jamaica. Road construction in the eighteenth century first disturbed the site, followed by further damage during Mandela Highway construction in the 1940s. The site now faces renewed threats from a proposed highway expansion that has divided it into two zones. In response, the Jamaica National Heritage Trust began archaeological investigations in 2016 to assess and document the land before development and preserve any recoverable material remains and cultural heritage. Field seasons from 2016 to 2019 recovered of several ceramic burial vessels from inhumation contexts, providing valuable …

Large Language Models And Networks: Edge Proposal, Synthetic Corpora, And Adaptive Node Generation, Nathan Gonzalez

Graduate Thesis and Dissertation post-2024

Natural Language Processing (NLP) and Artificial Intelligence (AI) have evolved from brittle rule-based engines through data-driven statistical models to today’s transformer architectures whose multi-head attention enables rich contextual reasoning. Against this backdrop, this dissertation unifies three complementary investigations that deepen our understanding of how large language models (LLMs) can reason over, generate, and strategically adapt language within networked settings. First, instruction-tuned LLMs are recast as latent-relationship detectors: by prompting models to hypothesize links between text-described entities, we recover edge sets that reconstruct social, thematic, and citation graphs with high precision, revealing how attention distributions encode topological cues. Recognizing the difficulty …

The concentration of MC-LR, and nutrients (ammonium, orthophosphate, and nitrite concentrations) were measured in the laboratory. Multivariate correlation, principal component analysis, and multiple regression were employed to determine dominant drivers of toxin occurrence. …

Exploring The Genetic Structure And Evolutionary History Of Marine Fish Populations Across Micronesia, Pavithiran Amirthalingam

Graduate Thesis and Dissertation post-2024

Most marine species exist as metapopulations, composed of subpopulations inhabiting patchily distributed habitat. Connectivity among these subpopulations is primarily facilitated by larval dispersal via ocean currents. Understanding patterns of population connectivity is crucial for evaluating metapopulation dynamics and ensuring long-term population stability in managed species. Micronesia, a vast region in the North Pacific with hundreds of islands, is the northern extent for many tropical species and is thought to function as vital stepping-stones between the central and western Pacific. However, limited phylogeographic studies in the region have left significant knowledge gaps regarding metapopulation dynamics. Here I address this knowledge gap …

Characterizing Muscle Control As An Emg Visual Matrix, Peter W. Makary

Graduate Thesis and Dissertation post-2024

Evaluating electrical muscle activity patterns using surface electromyography (EMG) is a widely used technique to assess movement in research settings, but its use has not been translated to clinical settings. This study aims to investigate the potential of evaluating muscle activity control through a visual matrix display. EMG data from older and younger adults collected in a previous seated locomotor perturbation study was used to generate visual matrices representing their lower-limb ankle muscle activity. Visual matrices from each condition consist of 20x20 grids, where each axis represents activity from an individual muscle of muscle pairs, such as the tibialis anterior …

Rethinking Trust In The Refugee Resettlement Process: How Service Providers Can Enable Refugee Agency Through Diasporic Connections, Mahfoudha Sidelemine, Emily D. Campion

Political Science & Geography Faculty Publications

Current guidance for refugee resettlement agency workers encourages the simultaneous pursuit of trust-building and administrative tasks (e.g., housing, transportation and employment). This dual goal is resource-intensive, and focusing on the former may come at a cost to the latter. The purpose of the current research is to challenge the importance of trust-building by resettlement agencies. Drawing from our qualitative data from in-depth interviews with resettled refugees (N = 20) and agency workers (N = 15), we adopt a grounded theory approach and find that the burden of responsibility for both caregiving and administrative responsibilities can overtax agency workers …

Under New Management?: Sovereign Wealth Funds And Their Ownership Of U.S. Sports Teams, Benjamin K. Moyer

Dickinson Law Review (2017-Present)

In October 2021, Saudi Arabia’s sovereign wealth fund (“SWF”) successfully purchased the English Premier League soccer team Newcastle United F.C. for $400 million. With this transaction, Saudi Arabia joined fellow Gulf countries, Qatar and the United Arab Emirates, in owning a major European soccer team through one of its state’s SWF. States have long used their SWFs to invest in foreign markets, but recent trends have transformed these originally strictly financial vehicles into political tools. Since the 2007–2008 financial crisis, many states have used their SWFs not only to produce financial gains but also to generate soft power through political …
