The Meaning Of Physical Activity In The Context Of Health Sciences: A Concept Analysis, Martín G. Farinola May 2026

The Meaning Of Physical Activity In The Context Of Health Sciences: A Concept Analysis, Martín G. Farinola

International Journal of Physical Activity and Health

Physical activity has been defined in numerous ways. Thus, this study aimed to conduct a concept analysis of the existing physical activity definitions in the health sciences literature to evaluate its conceptual precision and assess the need for a revised or novel concept better suited for this domain. The concept analysis was accomplished using tools derived from philosophical semantics. The analysis identified six definitions that explicitly state what physical activity is with sufficient clarity to allow for conceptual examination. The findings indicated that these definitions frequently merge the concept of physical activity with its contextual attributes. To address these semantic …

Predator Or Prey: The Analysis Of Gender And Race On The Perception Of Black Men As Sexual Assault Victims, Jordyn Livingston, Dr. Florencia Cornet

Caravel Undergraduate Research Journal

Men sexual assault victims have gained more attention in recent years. Despite the growing sociological literature on violence against men, previous research provides little acknowledgment of Black men sexual assault victims. In this manuscript, I analyze emerging literature in the socio-medical sciences to explore how gender and race affects the perceptions of Black men as sexual assault victims. Specifically, I utilize intersectionality as a theoretical framework to synthesize literature on blackness and masculinity in sexual assault victims to conclude that there is an intersectional point that disadvantages Black males, portraying them as sexual predators. In so doing, I provide research …


The Effect Of Stress Hormones On Memory Formation And Academic Performance, Emma L. Hooks May 2026

The Effect Of Stress Hormones On Memory Formation And Academic Performance, Emma L. Hooks

Senior Honors Theses

With chronic stress becoming increasingly prevalent in academic settings, researchers have identified significant effects on learning and academic performance. Cortisol, a glucocorticoid hormone, is released following the activation of the hypothalamic-pituitary-adrenal (HPA) axis and plays a vital role in the stress response. Although acute increases in cortisol can improve attention and memory, sustained activation of the stress response can impair memory, executive functioning, and academic performance. This thesis draws on neuroscience, psychology, and education research to examine how chronic cortisol exposure affects the hippocampus and prefrontal cortex, and how the effects manifest in learning and academic performance, particularly in developmental …

Measuring Disability Prevalence In Healthcare: A Study Comparing Two Disability Measures, Kristen L. Milefchik, Rhonda K. Dailey, Sharon Milberger

Developmental Disabilities Network Journal

People with disabilities experience significant health disparities and interventions are needed to address them. Measuring disability prevalence is an essential aspect of designing effective, data-driven healthcare strategies. Accurately measuring disability prevalence is challenging given disability is a complex phenomenon, with biological, social, environmental, and cultural components. Previous studies have compared a variety of disability status measurements and found that measurements were incongruent with each other. This study examines the concordance between disability status using two different measures: the nationally recognized American Community Survey (ACS-6) functional difficulty questions and one disability identity question. We used data from 3,621 adult patients participating …


The Intersection Between Adolescent Pregnancy, Mental Health Concerns, Stigma, And Sex Education, Madelon Cox May 2026

The Intersection Between Adolescent Pregnancy, Mental Health Concerns, Stigma, And Sex Education, Madelon Cox

Honors Program: Senior Projects (Public)

This thesis discusses research from the past two decades focused on factors contributing to an increased risk of adolescent pregnancy and the lasting impact of that pregnancy. The consequences of being a pregnant adolescent can be compounded by race, gender, socioeconomic class, and access to education. Adolescent pregnancy also carries significant physical and mental health risk for the adolescent and the child. Awareness and various interventions can help pregnant adolescents or those who may be at risk for adolescent pregnancy to support them, prevent isolation, and reduce further negative mental health conditions, such as depression and anxiety.

Ligand-Based Pharmacophore Modeling And Structure-Based Virtual Screening For Identifying Potential Therapeutic Agents Targeting The Sars-Cov-2 Spike Protein-Ace2 Receptor Interaction, Timoteo Delgado-Maldonado, Gilberto Vargas-Salas, Debasish Bandyopadhyay, Adriana Moreno-Rodriguez, Eyra Ortiz-Pérez, Gildardo Rivera-Sanchez

School of Integrative Biological & Chemical Sciences Faculty Publications

Coronavirus disease (COVID-19) remains a global health concern due to its high mortality and morbidity. In this study, we combined ligand-based pharmacophore modeling (LBPM) with structure-based virtual screening (SBVS) to identify novel inhibitors targeting the SARS-CoV-2 spike protein. Ligands from the MolPort database were screened via docking and molecular dynamics simulations at the receptor-binding domain (RBD). Four compounds showed promising docking scores (-8.7 to -6.4 kcal/mol) and dynamic stability (root mean square deviation < 5 Å). In vitro assays confirmed that compounds C3 (IC50 = 0.03 µM) and C4 (IC50 = 10.4 µM) effectively inhibited spike-ACE2 binding with low cytotoxicity (CC50 > 100 µM). These findings show the efficacy of the LBPM technique and highlight 1H-pyrazol-5-ol derivatives as potential building blocks for developing new antiviral agents against SARS-CoV-2.


Sepsis As An Immune Continuum: Cytokine Storm To Lymphopenia And Pics, Chelsey King May 2026

Sepsis As An Immune Continuum: Cytokine Storm To Lymphopenia And Pics, Chelsey King

Senior Honors Theses

Sepsis is a leading cause of morbidity and mortality worldwide, driven by a dynamic immune continuum that progresses from early hyperinflammation to profound immunosuppression. This review examines the three overlapping phases of sepsis: the inflammation-mediated cytokine storm driven by dysregulated PRR activation, NF-κB signaling, and NETosis; apoptosis-driven lymphopenia involving caspase-mediated lymphocyte death, dendritic cell dysfunction, and metabolic exhaustion; and prolonged immunoparalysis culminating in persistent inflammation, immunosuppression, and catabolism syndrome (PICS). Key mechanisms linking these phases, including the co-existence of hyper- and hypo-inflammatory states, are synthesized alongside relevant clinical biomarkers such as IL-6, HLA-DR, and single-cell immune profiles. This review highlights …

Addressing Nonignorable Missing Data And Heterogeneity In Prognostic Biomarker Assessment, Xinran Huang, Ruosha Li, Jing Ning, For The Alzheimer's Disease Neuroimaging Initiative May 2026

Addressing Nonignorable Missing Data And Heterogeneity In Prognostic Biomarker Assessment, Xinran Huang, Ruosha Li, Jing Ning, For The Alzheimer's Disease Neuroimaging Initiative

Faculty, Staff and Student Publications

Covariate-specific and time-dependent area-under-curve (AUC) is often used to evaluate the discriminative performance of biomarkers with time-to-event outcomes, particularly when certain covariates influence biomarkers' accuracy. In biomarker research, despite extensive efforts, missing data remain unavoidable, with nonignorable missingness posing significant challenges. This article focuses on estimating the impact of covariates on time-dependent AUC in the presence of nonignorable missing biomarkers. Assuming a parametric model on the missing probability, we leverage instrumental variables to address the identifiable issue and estimate the unknown parameters. We integrate the inverse probability weighting approach into the score equation of a pseudo partial likelihood for estimation …


Gestational Diabetes And Social Determinants Of Health In Black Women, Darianne Greenwood May 2026

Gestational Diabetes And Social Determinants Of Health In Black Women, Darianne Greenwood

Capstone Experience: Master of Public Health

Gestational Diabetes Mellitus (GDM) poses significant health risks, specifically increasing the risk of developing Type 2 Diabetes post-delivery, as well as increasing the risk of adverse neonatal and maternal outcomes. Black women, in particular, experience disproportionately higher rates of GDM incidence, severity, and complications in comparison to White women. Biological factors alone do not account for these disparities, necessitating a deeper examination into how systemic factors, particularly the social environment, influence these inequitable health outcomes. The purpose of this comprehensive literature review is to answer the question: “How do the Social Determinants of Health (SDoH), such as residential segregation, food …


Occupational Stressors And Health Impacts Among First Responders, Mason N. Roach Apr 2026

Occupational Stressors And Health Impacts Among First Responders, Mason N. Roach

Honors College Theses

The United States 911 emergency response system is an interconnected web of public services that seeks to provide its community with care, resources, and safety in times of need. However, the impact of this support on the employees providing the service often goes unnoticed. This review identifies and analyzes the unique strains on first responders' physical and mental health using the Job Demand-Control Model and the Allostatic Load Model. A review of available research literature supports the conclusion that occupational-related stress, including trauma exposure, shift work, poor leadership, and inadequate communication, can have long-lasting negative impacts on provider health.
