These methods can also provide critical insight into animal health, behavior, and stress responses without the need for invasive procedures or restraint, thereby minimizing harm and distress. This literature review will explore the practical applications of IRT, NIRS, and …

The Role Of Nicotine In Treating Neurodegenerative Diseases, Jacquelyn T. Deaton

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Neurodegenerative diseases have emerged as a critical medical challenge because they cause progressive neuronal death alongside structural or functional deterioration. Families, healthcare institutions, and affected individuals face significant challenges due to neurodegenerative diseases such as Alzheimer's, Parkinson's, and Huntington's diseases, which impair both cognitive function and motor abilities. Researchers have found that nicotine in tobacco products is a compound with therapeutic potential. This literature review explores how nicotine interacts with neurodegenerative mechanisms, such as oxidative stress and inflammation, and assesses its potential neuroprotective effects in conditions like Alzheimer's and Parkinson's diseases. In the central nervous system, nicotine binds to the …

Autoregressive Temporal Modeling For Advanced Tracking-By-Diffusion, Pha Nguyen, Rishi Madhok, Bhiksha Raj, Khoa Luu

Electrical Engineering and Computer Science Faculty Publications and Presentations

Object tracking is a widely studied computer vision task with video and instance analysis applications. While paradigms such as tracking-by-regression,-detection,-attention have advanced the field, generative modeling offers new potential. Although some studies explore the generative process in instance-based understanding tasks, they rely on prediction refinement in the coordinate space rather than the visual domain. Instead, this paper presents Tracking-by-Diffusion, a novel paradigm for object tracking in video, leveraging visual generative models via the perspective of autoregressive models. This paradigm demonstrates broad applicability across point, box, and mask modalities while uniquely enabling textual guidance. We present DIFTracker, a framework that utilizes …

A Qualitative Interpretative Meta-Analysis Of The Experiences Of Women Under Community Supervision, Gifty Kinful

Research Papers

Research reveals that women parolees or probationers encounter both challenges and support systems as they navigate their reintegration into the community. More specifically, most women returning from prison and those on probation are released into a society of stigma where access to housing, employment, education, transportation, and healthcare services is either severely limited or nonexistent. These serious obstacles can undermine their ability, motivation, and desire to succeed while on probation or parole. Support systems may be more or less available and effective. The qualitative literature on women under community supervision is large but to our knowledge, the diverse studies have …

Even In Death, Divided By Law: The Permanent Injustice Of Cemetery Segregation In Southern Illinois And The Legacy Of Isaac Burns, Local Civil War Veteran, Taylor Phillips

Southern Illinois University Law Journal

In death, are we truly equal? A Cemetery in Pinckneyville, Illinois, bears silent witness to a relentless history that preserves a racial divide thought to be buried away. Hidden in the segregated section lies Isaac Burns, an African American Civil War veteran, separated from those buried with honor. His grave lies alongside those of other African Americans buried in an area marked not by the unity of service but by the nation's refusal to see them as equals. Burn's grave is a reminder that the legacy of his sacrifice, once given in the name of unity and freedom, is overshadowed …

Advanced Interactions Of Directed Energy With Retinal Pigment Epithelial Cells And Their Photochemical And Photothermal Responses, Jin B. Ha

Theses & Dissertations

Excess optical radiation can injure the retina through either rapid heat deposition (photothermal damage) or cumulative photo‑oxidative stress (photochemical damage), yet current laser‑safety limits treat these mechanisms as independent. To test that assumption, this dissertation integrated systematic wavelength, duration and temperature‑controlled laser exposures with live/dead fluorescence imaging in a melanin‑loaded hTERT‑RPE1 monolayer model. First, concurrent 447 nm (blue) and 2 µm (infra‑red) beams delivered for 200 s demonstrated a strong thermal–photochemical synergy: each beam alone was sub‑threshold (≤25 % lethality) but together produced 100 % RPE death without exceeding 50 °C, proving that modest heating markedly lowers the photon dose …

Faculty Publications

Understanding the impacts of multiple environmental stressors on phytoplankton biomass is crucial for predicting marine ecosystem responses under global climate change. This study employed a sequential modeling framework integrating principal component analysis, generalized additive models, and artificial neural networks to improve predictions of phytoplankton chlorophyll a concentrations in the Taiwan Strait. Analyzing a decadal dataset, we found that a 2°C rise in sea surface temperature and a 0.2 pH decline will each lead to an 11.3% reduction in chlorophyll a biomass, whereas nitrogen enrichment is expected to increase it by only 2.8%. The combined effects of these stressors will result …

Cell Death Helps To Stabilize Populations Of Prochlorococcus, P. Wang, E. A. Laws, C. Liang, X. Liu, J. Chen, Y. Zhong, C. Li, B. Huang

Faculty Publications

Prochlorococcus is one of the dominant phytoplankton species in tropical and subtropical pelagic marine ecosystems. To maintain its population equilibrium in oligotrophic waters, the dominant species Prochlorococcus requires high loss rates to offset its high abundance and growth rates. While theoretical frameworks recognize multiple loss processes for Prochlorococcus (viral lysis, environmental stress, programmed cell death), prevailing population studies attribute main mortality to grazing. This oversight stems from in situ data gaps of non-grazing mortality processes. In this study, we firstly formulated simple differential equations that took account of population losses due to both grazing and cell death. We then used …

In The Name Of The Mother, The Nation, And The Race: White Women, The Jim Crow South, & Moralized White Supremacist Feminism, Shayna M. Lawson

Theses and Dissertations

This thesis introduces the concept of moralized white supremacist feminism to examine the central role white women played in constructing, legitimizing, and sustaining racial hierarchies in the Jim Crow South through a network of cultural and political organizing, particularly through the United Daughters of the Confederacy and Women’s Ku Klux Klan. Far from passive observers, white women were strategic agents of segregation, leveraging ideals of purity, motherhood, and moral virtue to enforce anti-Black violence and oppression through educational, civic, legal, and symbolic institutions, as well as extra-legal practices. Drawing from archival materials, oral histories, and critical race theory, this study …

Intergenerational Transmission Of Health: Evidence From Indonesia, Fatima Khan

Theses and Dissertations

This study estimates the causal transmission of health from mothers to their children. Intergenerational associations in health and other human capital outcomes are well established, but those associations may not be causal due to common unobserved factors between a mother and her child. This study employs two-stage least squares, using weather variation as an instrument, to causally identify the relationship between maternal health and child health outcomes in five dimensions: height-for-age, self-reported health, blood pressure, lung capacity, and hemoglobin levels. The data are from the Indonesian Family Life Survey (1993--2014), a longitudinal survey that provides a 21-year look into the …

A Quiet Privilege: Garrity, Internal Investigations, And The Need For A Preference Of Silence Among Public Employees, Jacob Abel

University of Florida Journal of Law & Public Policy

When a public employee is asked to testify against themselves or face termination, they are presented with a trilemma. They may choose to respond to questions falsely, answer truthfully, and suffer criminal sanctions, or remain silent and lose their job. In Garrity v. New Jersey, the Supreme Court resolved this trilemma by ruling that, when a public employee is compelled to answer questions, the Fifth Amendment grants the employee immunity for their testimony. The Supreme Court “solved” the trilemma again, in Gardner v. Broderick, by saying that an employee who is fired for invoking their Fifth Amendment right …

Where "Woke" And The Written Word Go To Die: How Florida's Newest Book Ban Law Violates The Fourteenth And First Amendments, Sarah N. Powell

University of Florida Journal of Law & Public Policy

The fight over banned books is as old as the nation itself. However, the number of book objections and removals in public schools has increased dramatically in the past two school years. According to PEN America, a national free speech group, Florida currently leads with the highest number of book bans in the nation: “[o]ver 40 percent of all book bans [in the U.S.] occurred in school districts in Florida.”

Vague statutory language and procedures in recent legislation have made banning books even easier. This Note challenges the constitutionality of section 1006.28, Florida Statutes (2024), one of Florida’s newest book …

Addressing The Supply Of Frozen Embryos In A Post-Dobbs America, Benjamin W. Akins, Vlad A. Bursuc

University of Florida Journal of Law & Public Policy

Over the past two decades, the supply of frozen embryos has exponentially increased in America. Today, estimates put the total amount of stored embryos at up to 1.5 million. In a post-Dobbs world, much uncertainty and anxiety exists as to what can and should be done with these embryos. In 2024, the panic became especially heightened when the Alabama Supreme Court ruled, in LePage v. The Center for Reproductive Medicine, P.C., that frozen embryos were eligible for the same protections as other minor children in civil wrongful death actions. This ruling, the first of its kind, opened the …

Improving The Screening And Management Process For Mental Health Disorders And Health Risk Behaviors In College-Age Students: A Quality Improvement Project, Brooke L. Styslinger

Doctor of Nursing Practice (DNP) Manuscripts

Establishing a standardized electronic screening process for mental health disorders and health risk behaviors is crucial for early identification and intervention before poor outcomes occur. This quality improvement project addresses a gap in care relating to screening practices in a college health services office which primarily relied on a provider-based interview screening processes in students reporting for care. Pre-implementation data showed providers most often screened for Major Depressive Disorder (MDD), alcohol use, and drug use, with inconsistent screening for Generalized Anxiety Disorder (GAD) or tobacco/vaping use. Follow-up screening form administration was also inconsistent, only given 3.3% of the time for …

Analyzing The Impact Of Interactive Home Monitoring On Congestive Heart Failure Readmissions: A Program Evaluation, Josh C. Riggs

Doctor of Nursing Practice (DNP) Manuscripts

Hospital readmissions are described as a situation in which a patient is admitted to a hospital within 30-days of being discharged from an earlier inpatient stay and is a critical indicator of care, contributing heavily to the rising healthcare costs in the United States. Heart failure is one of the leading contributors to 30-day hospital readmissions, prompting healthcare organizations to develop and implement policies aimed at reducing these occurrences. This program evaluation examined the effectiveness of the University of Virginia’s (UVA) Interactive Home Monitoring (IHM) program at reducing 30-day hospital readmission rates among patients diagnosed with heart failure (HF).

The Effects Of National Elite Signaling On Ranked Choice Voting In Utah, Mathew Woodman

All Graduate Reports and Creative Projects, Fall 2023 to Present

Ranked-Choice Voting (RCV) is a voting method used in few cities in the United States. There has recently been an increase in interest in adoption of the voting method in other cities using pilot programs, much like the one introduced in Utah. Ranked-Choice Voting has become a topic of contention with strong disapproval coming from opponents of the voting system. The questions are why there is disdain for Ranked-Choice Voting, and why such disdain seems to exist more heavily in Republican camps. Public opinion polling from “likely and confirmed Utah voters” in Salt Lake, Utah, and Grand Counties, conducted by …

Two Essays On Index-Based Risk Management In U.S. Rangeland And Livestock Production, Wajdi Belgacem

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation investigates two distinct but complementary dimensions of risk management in United States rangeland agriculture. Essay 1 measures spatial variation in basis risk within the Pasture, Rangeland, and Forage (PRF) rainfall-index program for 176 Nebraska grid cells (1988–2023). By linking official NOAA rainfall indices with 30-m Rangeland Analysis Platform biomass estimates, we find rainfall–forage correlations that peak at 0.45 but display pronounced heterogeneity. The probability that neither insured interval triggers during an actual forage loss averages 12%, rising to nearly 30% in several Sandhills cells, whereas optimally pairing late-spring and summer intervals reduces complete misses below 10%. These results …
