Essays On Health Economics, Quan Qi

Electronic Theses & Dissertations (2024 - present)

The first chapter examines whether Medicare Part D---the largest expansion of Medicare in recent decades---had a lasting impact on retirement behavior by providing subsidized prescription drug coverage to older adults. We employ a difference-in-difference-in-differences framework that compares changes in labor supply among individuals aged 65–68 versus 55–64 in a treatment group with employer-sponsored retiree health insurance (RHI) only until age 65, relative to a control group with lifetime RHI, before and after the 2006 implementation of Part D. Using data from Health and Retirement Study (2000-2018), we find that Part D reduces full-time employment by 6.52 percentage points among the …

Characterization Of Corticotropin Releasing Factor Receptor 2 In Stress-Regulating Regions Of The Mouse Brain, Jennifer J. Lafrican

Electronic Theses & Dissertations (2024 - present)

Sex differences in the morphology of the brain are thought to underlie the sex differences we see in anxiety and depression, where women are twice as likely to be diagnosed when compared to men. Stress, or a disruption to homeostasis, can exacerbate these mood disorders. Corticotropin releasing factor (CRF), and its receptors, play an important role in regulating the stress response. Binding of CRF with CRFR2 has been shown to reduce behavioral and neuroendocrine stress responses, yet whether there are sex differences in CRFR2 expressing neurons and stress-induced activation of these neurons in mice is unknown, in part due to …

A person’s family history and genes (DNA) affect how much grip strength they have. Previous studies have identified genes that affect grip strength, mainly in European ancestry populations. In this study, we examined whether these genetic elements predict grip strength in …

Dna And Protein Determinants For P63 Transcriptional Activity, Abigail Mccann

Electronic Theses & Dissertations (2024 - present)

The transcription factor p63 is critical for development of the epidermis and other epithelial-related structures. Mutations in the DNA-binding domain of p63 lead to a range of human developmental disorders characterized by symptoms such as ectrodactyly, painful skin dysplasia, and cleft lip and palate. The TP63 gene is also amplified in squamous cell carcinomas, contributing to tumor pathogenesis. While the importance of p63 in human health is well established, the mechanisms underlying its control of an essential gene network remain unclear. TP63 encodes multiple isoforms with distinct N- and C-terminal domains. The ∆Np63α isoform is directly linked to epidermal development …

Essays On Innovation And Labor Market Benefits, Kyoungah Noh

Electronic Theses & Dissertations (2024 - present)

The first chapter examines the impact of bank failures on team-based innovation, focusing on the persistence of inventor teams under credit supply constraints. Using U.S. patent and FDIC data from 2000 to 2012, this paper presents three main findings. First, bank failures significantly reduce both the number of team patents and the number of inventors with collaborators. Second, negative banking shocks decrease the likelihood that inventor teams remain together for projects in subsequent periods. However, team-specific factors, including geographic proximity, prior collaboration experience, and smaller team sizes, mitigate the adverse effects of bank failures and help preserve the stability of …

The Excessive Cost Of Health: An Analysis Of Pharmaceutical Accessibility Issues In The United States, Henry Woodman Curtis

Electronic Theses & Dissertations (2024 - present)

Compared to the rest of the world, the United States has one of the worst-performing health care systems. While this is influenced by our hospital systems and clinical care in certain contexts, one of the biggest culprits for our poor ratings is the cost and availability of prescription medications. We pay more than any comparable country for the exact same medications and have a harder time actually accessing them. In this dissertation, I aim to analyze how individuals, companies, and governmental agencies have responded to various instances of high-cost or low-availability prescription medications. To begin, I examine pharmaceutical patenting practices …

Association Of Non-Communicable Diseases With Severe Covid-19 Among People Living With And Without Diagnosed Hiv/Aids In New York State, Ravi Kumar Balu

Electronic Theses & Dissertations (2024 - present)

Background: People living with diagnosed HIV (PLWDH) have a higher chance of co-infections and co-morbidities than the general population. When SARS-CoV-2 was first reported in China in December 2019 and later declared a pandemic, it was speculated that PLWDH might be more prone to SARS-CoV-2 infection and severe disease outcomes given their increased vulnerability to other respiratory infections like influenza, pneumococcal pneumonia and tuberculosis. However, several facets of COVID-19 disease in PLWDH are incompletely understood, including whether non-communicable diseases (NCDs) are strong risk factors for severe disease outcomes and death as they are in the general population.

The Role Of The Nasal Migratory Mass In Olfactory Bulb Formation And Fertility, Charisse Martin

Electronic Theses & Dissertations (2024 - present)

The olfactory migratory mass plays an essential role in the development of the olfactory bulb by facilitating the migration of the gonadotropin-releasing hormone neurons from the olfactory placode to the pre-optic hypothalamic area in the brain. In mammals, the migration of GnRH neurons is critical for establishing the hypothalamic-pituitary-gonadal axis (HPG axis), which regulates reproductive function through the production and secretion of gonadotropins. Luteinizing hormone (LH) and Follicle-stimulating hormone (FSH) instruct the gonads to function appropriately, ensuring sexual maturation and fertility. Disruptions in this migratory pathway have been linked with Kallmann syndrome, a condition characterized by low levels of GnRH, …

Street Outreach And Reentry: The Role Of Community Violence Intervention In The Reintegration Of Returning Citizens, Hilary Jackl

Electronic Theses & Dissertations (2024 - present)

Amidst ongoing efforts to reduce the nation’s prison population, as well as calls to defund the police and invest in civilianized public safety strategies following the murder of George Floyd, community-based violence intervention (CVI) strategies have been increasingly recognized as a critical means by which to ameliorate the United States’ enduring gun violence problem without exacerbating the harms of overpolicing and mass incarceration. However, most contemporary CVI research has assessed program impacts on neighborhood rates of gun violence and has produced conflicting findings, leading scholars to call for the need to examine a wider range of program-related functions and outcomes. …

Comparison Of Methane Emission Quantification Methods At Landfills In New York State, Alexandra M. Catena

Electronic Theses & Dissertations (2024 - present)

Greenhouse gas (GHG) emission increases are a consequence of global population rise and economic growth. It is well known that carbon dioxide is the dominant GHG by mass, but methane has received increasing attention recently due to its high warming potential and relatively short lifetime of about a decade. Methane has several different types of both natural and anthropogenic sources including wetlands, waste management, energy, agriculture and farming, and wildfires, which makes tracking and reducing methane emissions a complex problem. The emission rates of each of these sources are highly uncertain due to differing emission estimation methods, which can be …

Teachers' Use Of Food Rewards In The Classroom Environment, Mckenna Fiore

UNF Graduate Theses and Dissertations

Food rewards are defined in terms of the value of a food to the individual at the time of ingestion. In classrooms, teachers may use food rewards to encourage academic achievement and appropriate classroom behavior (Hoffman et al., 2009). The use of unhealthy food rewards increases children’s desires for sweets and nonnutritive foods, which can pose risks for health and obesity-related outcomes, compared to healthier alternatives. Different characteristics, such as teaching style, classroom structure, teaching efficacy and teaching eating behavior, can be related to teacher’s use of different types of rewards. The goal of this study was to investigate the …

The Cultural Mechanisms Of Mental Health Stigma In Asian Americans, Vaishnavi Suren

UNF Graduate Theses and Dissertations

Asian Americans show hesitation seeking professional mental health services, as well as stigmatized attitudes towards help-seeking for mental health treatment in general. While the link between this stigma and lack of help-seeking is clear in past studies, there is a gap in the literature in looking at how various cultural mechanisms important to traditional Asian cultures interact with one another to contribute to mental health stigma. The goal of the current study was to examine intergenerational conflict, saving face, and temporal orientation to predict mental health stigma among Asian Americans. Participants (N = 208) were all second-generation Asian American …

A Pilot Study Of The Freeze Response: Physiological Markers Under Threat Versus Safety Video Conditions, Ula Mccarthy

Computational Pangenomics And Machine Learning For Genotype-Phenotype Analysis, Tejaswi Vemuri

UNF Graduate Theses and Dissertations

Phenotypes are the observable characteristics of an individual organism. Predicting quantitative phenotypes from genomic variation remains challenging when causal signals span both local motifs and distal regulatory contexts. Building on Frequented Regions (FRs)—subsequences conserved across genomes and extracted from a pangenome graph generated from a large collection of closely related species—we compare several modeling strategies across 35 Saccharomyces cerevisiae growth phenotypes: Random Forest (RF) on FR counts (called RFCounts), RF on FR sequences, 1D convolutional neural networks (CNN) on FR sequences, Long Short-Term Memory (LSTM) networks on FR sequences, a Genomewide Association Study (GWAS) baseline, and a sequence-based transformer model, …

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 …

Exploring The Connections Between Social Media Posts About Intimate Partner Violence And Their Influence On Women’S Physical And Mental Health, Joanna Lynn

UNF Graduate Theses and Dissertations

Intimate Partner Violence (IPV) can happen to anyone and is considered a common occurrence in the United States (U.S. Department of Justice, 2025). Social media platforms have allowed individuals to post about their IPV experiences, but such posts can be met with negative comments that are not beneficial to the survivor. This study explores how social media posts regarding IPV affect an individuals’ mental and physical health through a quasi-experimental design.

Postnatal Programming Of Infant Temperament At 12-Months: A Test Of Lactation Programming Theory, Lydia Bierce

Electronic Theses & Dissertations (2024 - present)

The current study examined how maternal cortisol and breastfeeding duration across the first six months postpartum might relate to infant temperament profile membership at 12 months in 322 low-income Mexican American mother-infant dyads (46.3% male). Results revealed that maternal postnatal cortisol levels were significantly moderated by breastfeeding duration to predict infant temperament profile (β = 0.14, p = .030) such that more maternal cortisol was linked to higher likelihood of belonging to a high positive affect, well-regulated profile when mothers breastfed for above average durations. This suggests that while maternal cortisol in breastmilk might initially shape infant negative temperament, …
