The Mortality Effects Of Daily Ambient Pm2.5 Concentrations By Urbanicity In North Carolina, Pargoal Lisa Arab

Public Health Theses

Daily ambient PM2.5 (particulate matter ≤ 2.5 µm) concentration poses substantial health risks. PM2.5 comes from various sources, leading to regional differences in concentrations. Urban areas generally experience higher PM2.5 concentrations compared to rural areas. However, urban-rural differences in the relationship between daily PM2.5 concentration and adverse health effects remain unclear. The mortality effects of daily PM2.5 concentration across all counties in North Carolina were analyzed both temporally and spatially over a five-year period (2015-2019). A two-stage time series analysis was conducted using a quasi-Poisson regression model with various lag structures to estimate the relative mortality risk for each county. …

Assessing The Costs Of Illness Attributable To Leptospirosis, Alyssa Chetrick

Public Health Theses

Leptospirosis, caused by the spirochetes of the genus Leptospira, is a zoonotic bacterialdisease endemic to tropical regions and lower middle income countries (LMICs). Leptospirosis causes an estimated 1 million cases and more than 58,900 deaths annually.(Costa et al., 2015; Torgeson et al., 2015) In addition to human health, leptospirosis significantly impacts animal health and the livestock industry, particularly through reproductive losses, increased treatment costs, and decreased milk production, which exacerbates global insecurity.(Bennet, 2015; Torgeson et al., 2015) The estimated global cost loss to productivity due to disease is estimated at Int$ 29.3 billion. (Agampodi et al., 2023) Because of its …

Scale-Up Of Access To Medication For Opioid Use Disorder For People Who Inject Drugs On Parole In Ukraine: A Modeling Analysis, Brendan Caver

Public Health Theses

Background: Human Immunodeficiency Virus (HIV) and opioid-use disorder have long beendescribed as a syndemic; the two health issues go hand-in-hand to exacerbate each other (Perlman & Jordan, 2018). While the HIV pandemic has improved greatly in many regions such as the United States over the past several decades, it continues to become worse in Eastern Europe and Central Asia. HIV prevalence and opioid dependence are particularly high in carceral settings, but access to opioid agonist therapy (OAT) is extremely limited. This paper shows the results of a modeling analysis undertaken to see the impact of opioid agonist therapy (OAT) scale-up …

Environmental Justice Dimensions Of Orphaned Oil And Gas Wells In The United States, Grace Marie Hauser

Public Health Theses

Orphaned oil and gas (O&G) wells can leak methane and other hazardous pollutants,contributing to air and water contamination that threatens public health while also imposing financial burdens on local governments and taxpayers for remediation. However, the environmental and public health impacts remain understudied, in part due to limited understanding of the number and location of orphaned O&G wells. In this thesis we aimed to (1) create a national orphaned wells dataset covering years through 2024, (2) estimate the count and distribution of orphaned wells in the United States through 2024, and (3) evaluate the association between community environmental justice (EJ) …

Environmental Gentrification And Health: An Exploratory Analysis Of New York City, Joyce Hu

Public Health Theses

Background: Environmental gentrification is an emerging field seeking to understand the integrated effects of environmental improvements and gentrification. To date, we have a limited understanding of how to analyze environmental gentrification with intersecting health impacts. Our exploratory study investigates this relationship in New York City, where environmental improvement policies coincided with gentrification between 2000-2016. Methods: Using a census tract-level index of gentrification and corresponding environmental exposure data on air quality and vegetation, we conducted a clustering analysis to group and label census tracts according to environmental gentrification patterns. We then performed covariate-adjusted multivariable regression analyses to evaluate the association between …

Universal School Meal Programs At The State-Level: Assessing The Next Iteration Of Child Nutrition Policy For A New Generation Of Students, Grace V. Manes

Public Health Theses

BackgroundEight states have passed legislation to codify universal school meal programs (USMPs) for public and nonprofit schools. These programs provide free school breakfasts and lunches to all students with no exclusions. A strong link exists between health, education, and social outcomes and the presence of subsidized school meal programs, and these outcomes are often used to advocate for such programs. This study assesses the prevalence of other state policies passed to address health, education and social outcomes (Medicaid expansion, universal pre-k, and state child tax credits) among states which have also passed USMP policies. We hypothesized that USMP passage would …

Characterizing The Genetic Diversity Of Pfrh5 In Plasmodium Falciparum Clinical Isolates From Burkina Faso, Ghana, And Tanzania: A Next-Generation Sequencing Study To Inform Blood-Stage Malaria Vaccine Development, Manuel Emilio Perez

Public Health Theses

The development of a highly effective malaria vaccine is of global health priority, given the persistently high malaria burden in Sub-Saharan Africa (SSA) and growing resistance to antimalarial treatment and vector control measures. P. falciparum reticulocyte-binding protein homolog 5 (PfRH5) has emerged as a leading target among blood-stage malaria vaccine candidates due to its essential role in erythrocyte invasion and initial documentation of limited polymorphisms. However, recent studies have revealed greater PfRH5 genetic diversity than previously believed, raising concerns about potential parasite evasion of vaccine-induced immunity. This study utilized deep targeted amplicon next-generation sequencing to characterize PfRH5 genetic variation in …

Global Comparison Of Children’S Exposomes, Inumidun Oyebode

Public Health Theses

Environmental influences impact health, often with enhanced susceptibility for theyoung. Understanding the sources of these environmental factors is critical for mitigating exposures. Globally, children are exposed to many sources that differ by policy, urbanization, and socioeconomic conditions. Specifically, urbanization creates variation in exposure sources that differ in rural (refuse combustion, cooking biomass combustion, indoor residual spray) and urban areas (vehicle combustion, industrial activity). Differences in policy further shape these exposure patterns by regulating pollution sources, chemical use, and environmental protections across countries. This thesis evaluated environmental exposures of children living in United States, South Africa, and Singapore contributing to a …

Assessing Environmental And Sociodemographic Risk Factors For Leptospira Infection In A Urban Informal Settlements: A Study In Salvador, Brazil, Sebastian Alonso Salazar

Public Health Theses

Background: Leptospirosis is a neglected zoonotic disease that disproportionately affects people living in areas with poor sanitation, water contamination and rodent infestation such as urban informal settlements. More than one billion people worldwide reside in such communities, and with increasing urbanization, coupled with environmental change, the risk of Leptospira transmission continues to increase. Despite its global burden, this disease is often underreported due to diagnostic challenges and limited healthcare access, particularly in urban informal settlements. Understanding the incidence and risk factors in these settings is essential for improving public health interventions. This study aims to estimate the annual incidence of …

The Sand Creek Massacre And The History Of Greater Reconstruction In The American West, Anna E. Plotnick

Dissertations and Theses

In the traditional U.S. historical narrative, the Civil War & Reconstruction era is a North vs. South story. Nevertheless, the era of western expansion, a central theme throughout the nineteenth century, has no contingent place within this traditional narrative. Meanwhile, the history of the American West and its diverse peoples appears in many textbooks as an unrelated albeit contemporaneous narrative. Separated by geographical regions, historians often do not examine these concurrent histories. However, many of these historical events and actors were interconnected. As I am interested in understanding the Reconstruction era’s national impact, I intend to explore how Reconstruction policies …

Crowding-In Between Public And Private Investment In Developing Countries, Wally Bargeron

CMC Senior Theses

The tendency for public investment to crowd-in or crowd-out private investment is the subject of controversy in economic literature. This paper studies the relationship between public and private investment in fixed capital from 1970 to 2019 in 68 developing countries across Africa, Asia, Eastern Europe and Latin America. I find evidence for a crowding-in relationship between public and private investment overall. The crowding-in effect is larger in countries with high scores for measures of good governance, including a score that measures legal framework for businesses and a score that measures corruption.

Symbols Of Sovereignty And How They Speak To Us: Reading Contemporary Wampum Artwork In New York State Museums, Marie Peterson

Electronic Theses & Dissertations (2024 - present)

Contemporary Haudenosaunee artworks in exhibit spaces across New York State are bringing cultural information and counter-historical narratives to the public that they might not encounter otherwise. Artwork that includes wampum depictions or materials has heuristic qualities that can engage viewers with Haudenosaunee ways of knowing and relating. Wampum heuristics and Haudenosaunee scholarship are employed to interrogate how wampum materials were collected, categorized, and researched by the New York State Museum during the salvage anthropology era. The narratives embedded in wampum artworks are traced from this salvage era history, throughout the century between the salvage era that began at the end …

Adaptive Evolution Shapes The Transmissibility Of West Nile Virus In New York State, Sean M. Bialosuknia

Electronic Theses & Dissertations (2024 - present)

Arthropod-borne viruses (arboviruses), which are maintained in nature in complex transmission cycles involving hematophagic invertebrates and their vertebrate hosts, are the cause of a significant and expanding global health burden. Defining arbovirus-host interactions is necessary if we are to understand the adaptive and epidemiological potential of arboviruses. The results presented with West Nile virus (WNV Flaviviridae: Orthoflavivirus), are a compilation of such studies. WNV is the most prevalent arboviral pathogen in the U.S. and the most geographically distributed arbovirus in the world. Despite the evolutionary potential of these RNA viruses, WNV and other arboviruses have experienced only limited …

Socio-Economic And Infrastructural Determinants Of Response Time Disparities Across Emergency Service Agencies, Alice N. Ottah

Electronic Theses & Dissertations (2024 - present)

This study comprehensively analyzes the determinants of disparities in emergency response times for EMS, Fire, and Police agencies in San Francisco from 2021 to 2023, utilizing a multilevel modeling framework and publicly accessible data. Contrary to a primary reliance on structural neighborhood factors, this research reveals that while neighborhood disadvantage statistically significantly interacts with agency type to influence response times, its direct effect is weak and not uniformly consistent across services. Specifically, the analysis demonstrates that variance in call response times across neighborhoods is minimal (Intraclass Correlation Coefficients < 0.02), the effects of disadvantage are agency-specific (null effects for Police and Fire), and even when significant (for EMS calls only), response times are faster in more disadvantaged neighborhoods. These findings challenge the existing literature on emergency response times and highlight the need for tailored policy interventions that consider both neighborhood context and agency-specific operations to promote equitable emergency response.

Solar Energy Prediction Using Advanced Hybrid Machine Learning Models, Jelawi A. Alqhtani

UNF Graduate Theses and Dissertations

Accurate short-term forecasting of solar power generation is critical for the reliable and cost-effective operation of renewable-based microgrids, where sudden weather-induced variability can compromise grid stability, battery scheduling, and energy trading decisions. Traditional physical and statistical models struggle to capture the complex non-linear relationships and localized weather effects, while individual deep learning architectures often exhibit systematic biases such as chronic under-prediction of peak generation. This thesis proposes a novel Cross-Feedback Ensemble framework that combines the complementary strengths of Long Short-Term Memory (LSTM), Gated Recurrent Unit (GRU), and one-dimensional Convolutional Neural Network (1D-CNN) models through an iterative cross-feedback mechanism and a …

The Limits Of Strategic Adaptation: Continuity And Change In German And Russian Strategic Culture, Andrew W. Rios

UNF Graduate Theses and Dissertations

This thesis paper adopts a comparative historical analytical approach to German and Russian strategic culture. It examines numerous historical, cultural, and ideational variables that have guided German and Russian strategic initiatives, particularly since the end of the Cold War. It illuminates the ways in which these factors have contributed to the diverging paths of strategic adaptation adopted by Germany and Russia since the 2022 invasion of Ukraine. Utilizing theoretical concepts from strategic culture theory, historical and sociological institutionalism, and critical juncture theory, this paper argues that the Russian invasion precipitated a fundamental shift in Germany's strategic orientation vis a vis …

The Fiction Of Possibility: How Possible Worlds Theory Explains The Impossible Worlds Of Science Fiction, Jacob Burlingame

Graduate Research Theses & Dissertations

This dissertation explores the ways that science fiction texts convey to the reader the worlds in which they are set. It identifies four main strategies through which a science fiction text conveys its world: Neologisms, Secondary Texts, Actual-World Analogs, and Exposition. Neologisms include any words that are coined by the author to describe an entity that only exists in the text world, which creates a fuller world by creating a referent for them. Secondary Texts are any other documents alluded to by the primary text, whether created for the text world or imported from the actual world; these secondary texts …

Red Diplomacy And Black Liberation: The Cold War's Influence On The Naacp, Natalie A. Filkins

Honors College Theses

The Civil Rights Movement and Cold War occurred concurrently, yet the two events represent entirely different moments in American history. While one marked a moment of immense social growth, the other illustrated how widespread paranoia can influence a nation’s decision making. This thesis centers on an examination of how the National Association for the Advancement of Colored People (”NAACP”) utilized international bodies, like the United Nations (“UN”), to bring global attention toward the mistreatment of those of African descent. My analysis relied on internal documents from the NAACP’s offices, and the organization’s magazine publication, The Crisis. I examined volumes 55-68 …

Α Novel Ai-Based Modeling With Bias Classification Hybrid Risk Evaluation System For Confidence Enhanced Network Meta-Analysis Of Occupational Hazards And Burnout Risk Among Public Health Inspectors, Ioannis Adamopoulos

Mesopotamian Journal of Artificial Intelligence in Healthcare

Public Health Inspectors (PHIs) serve a critical role in enforcing health and safety regulations, particularly under the growing pressures of climate change. With rising exposure to occupational hazards such as heat waves, air pollution, and vector-borne diseases, PHIs now face escalating stress and burnout. Geographical variability, limited resources, and institutional gaps in training and support further shape their complex risk profile. Despite growing concern, systematic, confidence-based evaluations of these occupational risks—especially tailored to PHIs—remain rare. This study addresses that gap using a Confidence in Network Meta-Analysis (CINeMA)-enhanced framework to assess domain-specific occupational risk profiles of PHIs working in climate-stressed environments. …

Hillslope Degradation: Coarse Sands May Move Faster But Fines Dominate Flux, Robert Chance

Theses and Dissertations

Hillslopes are one of the most pervasive landforms on Earth yet the details of the processes that drive their evolution are not completely understood. Excluding boulders, the majority of mass and volume in soil-mantled hillslopes is composed of sand-sized and finer grains. Understanding the transport rates and governing transport mechanisms of these grains is therefore key to advancing our knowledge of hillslope evolution.This research investigates sand-sized sediment transport through field experiments at 20 sites tracking surface sediment motion and 11 sites measuring depth-dependent transport. These empirical results are compared against outputs from a novel grain-based hillslope diffusion simulation (GBHDS), which …
