Paediatrics and Child Health, East Africa

Background Sepsis is a leading cause of neonatal mortality in sub-Saharan Africa (SSA), where microbiological diagnostic capacity and antibiotic access are limited. High antimicrobial resistance (AMR) rates limit the effectiveness of current treatment guidelines, with concern that available antibiotics are rarely adequate treatment for neonatal sepsis in the region.

Methods A cross-sectional online survey was electronically distributed in English, French and Portuguese to neonatal clinicians across SSA between April and June 2025. Questions focused on the management of neonatal sepsis including diagnostic, antibiotic and guideline use. Responses were analysed descriptively and presented as percentages of the total number of responses. …

The Relationship Between K–12 School Administrators’ Adaptive Leadership Behaviors And Self-Efficacy For Crisis Management, Meg Anne Sheehan

This quantitative correlational study addressed the relationship between K–12 school administrators’ adaptive leadership behaviors and their self-efficacy for crisis management. Guided by Ronald Heifetz’s adaptive leadership theory and Albert Bandura’s self-efficacy theory, the study was an exploration of how adaptability, prior professional experience, and crisis-specific training influence administrators’ confidence in leading through emergencies. Participants included 51 practicing administrators from public schools, mostly located on Long Island, New York, who completed two validated instruments: the Adaptive Leadership Behavior Scale, which is an adaptation from Shams et. al, and the School Administrator Preparedness and Self-Efficacy Questionnaire, which is an adaptation of April …

Anti-Sars-Cov-2 Nucleoprotein Iga Is Associated With Worse Disease Severity In Critically Ill Covid-19 Pneumonia Patients, David Brett-Major, Dylan S. George, Eric D. Morrell, Carmen Mikacenic, Julie Carstens, Laura E. Evans, Mark M. Wurfel, Pavan K. Bhatraju, M. Jana Broadhurst

Journal Articles: Epidemiology

While humoral responses to vaccination and infection have largely focused on IgG, there is an evolving literature on ways in which IgA may drive neutrophil activity in lung injury secondary to viral infections, including COVID-19. We evaluated 238 immune-naïve, critically ill patients in the first year of the COVID-19 pandemic. Employing a laboratory-developed, multiplexed antibody testing, clinical history, medical record, and machine learning, we pursued relationships between systemic IgA and disease severity. Individuals with elevated anti-N IgA had 4-fold odds of more severe disease. This work emphasizes the importance of continued work to understand how different elements of the immune …

Ocular Surface Disease Following Lasik And Cataract Surgery: A Review Of Their Interrelated Complications, Matthew D. Spangler, Nila Kirupaharan, John D. Sheppard

Department of Ophthalmology Faculty Publications

Background: Ocular surface disease is a multifactorial condition that is very commonly caused by dry eye disease (DED). Ophthalmic procedures intended to improve visual outcomes, laser-assisted in situ keratomileusis (LASIK) and cataract surgery, can paradoxically cause or exacerbate underlying ocular surface disease. This results in worsening vision and quality of life.

Areas covered: This review examines the pathophysiological mechanisms contributing to ocular surface disease development following LASIK and cataract surgery. Both procedures are associated with the transection of corneal nerves, leading to decreased tear production, surface instability, altered neurotrophin production, and impairment of the blink reflex. Furthermore, these incisional procedures …

Modulation Of Prussian Blue Redox Signaling By Molecular Imprinting For Reagent-Free Electrochemical Detection Of Emtricitabine, Abdellatif Ait Lahcen, Gymama Slaughter

Center for Bioelectronics Publications

Reagent-free electrochemical sensors offer significant benefits for rapid, affordable point-of-care drug testing. In this study, we introduce a novel, reagent-free electrochemical sensor based on a molecularly imprinted polymer (MIP) specifically designed for the selective detection of Emtricitabine (FTC), a common antiretroviral used in HIV therapy. The sensor uses laser-induced graphene (LIG) electrodes, renowned for their high conductivity and porosity, ideal for electrochemical sensing. To enable reagent-free operation, the LIG surface was electrochemically coated with Prussian Blue, serving as a redox-active layer. Next, an MIP-PPy film was electropolymerized onto the Prussian Blue surface in the presence of FTC as a template, …

West Nile Virus Transmission Suitability Modeling For Culex Pipiens Via Temperature And Humidity, Hunter Jones, David Brett-Major, Joseph R. Fauver, Yeongjin Gwon, Jesse E. Bell

Journal Articles: Epidemiology

West Nile Virus (WNV) is the leading cause of mosquito-borne disease in the United States, yet predicting its transmission remains a significant challenge for public health officials. Many studies use correlative statistical models to predict disease cases using temperature and humidity, but accessible mechanistic approaches that simulate mosquito behavior traits can capture more of the transmission process. This study adapts an existing R-language package, the Mosquito-borne Viral Suitability Estimator (MVSE), which was created to model Aedes aegypti mosquito transmission of dengue, and tunes it to Culex pipiens transmission of WNV. Equations for mortality, biting rate, and incubation period were updated, …

Equity In Place, Segregation, And The Phillips Neighborhood, Myron W. Orfield

Articles

This Article describes an existential legal and factual conflict about residential segregation. It is centered in a neighborhood a few blocks north of where George Floyd—and more recently Renee Good—were murdered. Five years before Floyd’s murder, the conflict reached a breaking point, resulting in three lawsuits. One involved federal civil rights and two involved state civil rights claims that housing policy was causing deeper residential and educational segregation. Much of this debate was summarized in a series of articles in the journal Housing Policy Debate before the lawsuits were filed.

On one side were proponents of greater residential and educational …

Antimicrobial Activity Of Violacein Extracted ​ From Janthinobacterium Lividum​, Catherine M. Brownhill-Slatore

Scripps Senior Theses

Abstract

Antibiotic-resistant bacteria have been a threat since the discovery of antibiotics. The increased rise of antibiotic-resistant bacteria has created an immediate need for new antibiotics. Violacein, a purple bisindole pigment produced by Janthinobacterium lividum, has been shown to be a promising new antibiotic. Its efficacy has not been completely demonstrated, and this project aims to further investigate the effectiveness of violacein as an antibiotic. To do this, a minimum inhibitory concentration (MIC) test was conducted. Violacein was grown, extracted, purified, and tested across concentrations ranging from 1.0 to 500.00 µg/mL to cover values well above and below previously cited …

The Presence Of Predators Moderates Evolutionary Responses Of Trinidadian Killifish To A Novel Parasite, Anne E. Christian

Biology Dissertations

The Healthy Herds Hypothesis suggests the idea that prey populations derive a benefit from their predators: predators reduce the exposure of their prey to infectious disease, both by limiting prey population densities and by eliminating sick individuals. Much research has focused on the balancing effect that predators have on ecosystems. There is a current need for research into whether these effects cause evolutionary shifts in prey populations, where strong predation pressure prevents prey species from evolving physiological tolerance or resistance to infectious agents. Parasites especially often have rapid effects on host evolution, due to exploitative interactions.

I seek to address …

The Effects Of Nature Exposure On Workplace Engagement, Allison Emmons

Senior Honors Theses and Projects

The idea that nature is beneficial to humans is somewhat unclear in the field of psychology. Many studies have found that exposure to natural elements can improve human emotions and performance on cognitive tasks. However, there are inconsistencies in the literature regarding whether both outcomes can be enhanced at once. There is also limited research on how nature can impact attitudes about the environment and tasks at hand. This study seeks to examine whether or not incorporating natural elements into workplaces improves employee performance and engagement measures, such as decision-making quality, job satisfaction, job motivation, and current emotional state. This …

Qualitative Exploration Of Covid-19 Vaccine Uptake Among Healthcare Workers In Sierra Leone: Do The ‘Trusted Messengers’ Trust The Vaccine?, Ifeolu David, Enid Schatz, Wilson Majee

Population Health Leadership and Analytics Faculty Publications and Presentations

Introduction

Vaccine hesitancy is a global issue, and the important role of healthcare workers in addressing vaccine hesitancy is well documented. However, there is limited theory-guided research on the uptake of COVID-19 vaccinations among healthcare workers in low- and middle-income countries (LMICs). This study examined COVID-19 vaccine uptake among healthcare workers in Sierra Leone and assessed the relevance of the 5C model—which posits that vaccine uptake is shaped by confidence, complacency, constraints, calculation and collective responsibility—in explaining their vaccination attitudes, intentions and behaviours.

Methods

24 indepth interviews were conducted in 2022 with healthcare workers in Freetown, Makeni and Kenema. The …

Information Technology Dashboard Design Research, James Myers

Dissertations and Theses

Dashboard displays in command center environments benefit from design guidelines informed by perceptual and cognitive research. This dissertation examines how spatial hierarchy and chartjunk affect knowledge retention from dashboard displays, using a mixed-methods approach that combines formative qualitative studies with controlled experiments. Three formative studies, an expert review, a heuristic analysis with three reviewers, and semi-structured interviews with IT professionals identified spatial hierarchy and chartjunk removal as the design guidelines most likely to affect dashboard comprehension. A subsequent co-creation study with IT professionals refined these findings and informed experimental stimulus development. Two experiments tested these guidelines using a dashboard knowledge …

Mitochondrial Transfer To Granulocytic Myeloid-Derived Suppressor Cells Augments Immunosuppressive Activity, Prabhakar Arumugam, Cortney E. Heim, Rachel W. Fallet, Dhananjay Shinde, Vinai Chittezham Thomas, Rafael J. Argüello, Tammy Kielian

Journal Articles: Pathology and Microbiology

The anti-inflammatory properties of granulocytic myeloid-derived suppressor cells (G-MDSCs) promote Staphylococcus aureus (S. aureus) biofilm persistence. Evidence suggests that G-MDSC activity is shaped not only by S. aureus products but also by intrinsic metabolic programs. This study explores whether G-MDSC activity can be modulated by increasing mitochondrial abundance using a co-culture paradigm with macrophages as a mitochondrial donor. Macrophages transfer mitochondria directly to G-MDSCs via tunneling nanotubes, enhancing G-MDSC respiration, as reflected by increased basal, maximal, and spare respiratory capacity. Augmenting mitochondrial abundance in G-MDSCs enhances T cell-suppressive activity and reduces tumor necrosis factor (TNF) and interleukin 6 (IL-6) production. …

The Deregulation Of Cancer, Daniel G. Aaron

Utah Law Faculty Scholarship

Fifty years ago, the U.S. embarked on a radical new path. Under pressure from the environmental movement, Congress passed an array of statutes aimed at regulating carcinogens out of our world. This regulatory experiment sprawled from air and water to food and consumer products.

Legal scholars have paid scant attention to this wave of cancer regulation despite its size and importance and the public’s apparent interest in avoiding carcinogens. But there is a growing literature finding flaws with individual regimes within the framework, such as the Clean Air Act, the Toxic Substances Control Act, and the Tobacco Control Act. In …

Deterrence Without Peace: Nuclear Weapons And The Rising Threshold Of Warfare, Catie Clarke

CISLA Senior Integrative Projects

Nuclear weapons fundamentally changed the international political landscape, leading to the emergence of deterrence theory and the notion of the Long Peace. This paper challenges these claims, arguing that nuclear weapons facilitated a more violent and volatile international system rather than stability. Drawing on constructivist theory, this paper develops the Threshold of Violence framework – a normative model which asserts that nuclear weapons elevated the perceived upper limit of tolerable violence in international politics. This raised threshold generated three trends in the nuclear era: increased frequency of proxy wars, escalating levels of benefactor involvement, and greater severity of conflicts fought …

Asymptotic Profiles And Disease Prevalence At The Steady State For An Sis Patch Model, Daozhou Gao, Xin Li

Mathematics and Statistics Faculty Publications

Infected individuals often display mobility patterns that differ significantly from those of healthy individuals-traveling less frequently, covering shorter distances, visiting fewer destinations, and altering their timing and modes of movement. In this paper, to explore the influence of changes in travel frequency and destination on the spatial spread of infectious diseases, we propose a susceptible-infectious-susceptible patch model in which susceptible and infected populations have different dispersal rates and connectivity matrices. We first establish the threshold dynamics in terms of the basic reproduction number R-0 and show the existence and uniqueness of endemic equilibrium (EE) when R-0>1. Then we examine …

Spatial Temporal Modeling Of Infectious Disease Patterns In Texas, Robert E. Lashbrook

Earth & Environmental Sciences Theses

The Texas Department of State Health Services monitors numerous notifiable conditions statewide, including Campylobacter, Salmonella, Shiga toxin-producing Escherichia coli (STEC), Rabies, and West Nile virus (WNV). Given the substantial health, economic, and public health burden associated with these conditions, improving prediction is an important step toward reducing their overall impact. This study evaluated whether external demographic, social, climate, and environmental data could improve prediction of county-year disease activity across Texas. County level data was analyzed using supervised machine learning models, including linear regression, ridge regression, multilayer perceptron, random forest, XGBoost, as well as K-means clustering to identify broader …

Introduction: Human papillomavirus type 16 (HPV16) E6 antibodies may be an early biomarker of anal cancer. We cross-sectionally evaluated when in the course of anal disease, HPV16 antibodies are induced. Methods: A nested case-control study of 846 men who have sex with men (MSM) was conducted within a prospective study of men with and without HIV. Cases of anal HPV16 (N=262), biopsy-confirmed high-grade squamous intraepithelial lesion (HSIL;N=140), and anal cancer (N=21) were individually matched to controls (N=423) on HIV status, study-participation duration, and age. Serum samples closest to diagnosis underwent HPV serologic testing; prediagnostic serial samples were tested for anal …
