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. …

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 …

An Engine, Not A Vessel: Place, Politics, And Health In The United States, Philip B. Rocco

Political Science Faculty Research and Publications

Social scientists often treat places as containers for social and economic phenomena that shape health outcomes. Yet this analytic practice conceals more than it reveals. Local governments in the United States should be understood as engines of both health promotion and stratification. As the contributions to this symposium suggest, governments not only occupy a formal place in the U.S. public health system, their decisions on everything from housing to transportation infrastructure can also have profound impacts on health outcomes. Local political economies likewise renegotiate the parameters of acceptable health interventions, public understandings of health disparities, and the status of population …

Ebola In The Drc: A Different Problem Compounded By Violence, David Brett-Major

Journal Articles: Epidemiology

A Public Health Emergency of International Concern (PHEIC) has been declared in the Democratic Republic of Congo (DRC) due to Ebola disease from Bundibugyo virus. Non-health-focused factors should be fundamental to how DRC and its partners respond to and recover from the current emergency. Filovirus emergencies are violent in every sense-the disease experience of patients and their caregivers, the tumult in impacted communities, sometimes the physical manifestations of frustration against healthcare services, the fits and starts of concerted response, and the milieu of conflict in which this emergency occurred. Yet, interpersonal and organized violence may contribute to frequency of health …

Ancient Immune Systems: Sensing And Signaling In Bacterial-Phage Conflict, Cameron Grace Roberts

Student Theses and Dissertations

Viruses are among the most significant selective pressures shaping the evolution of life on Earth. In the microbial world, bacteriophages (phage) are bacterial viruses and drive a continuous evolutionary arms race that has led to an extraordinary diversity of bacterial defense mechanisms [1]. These systems are thought to have provided the evolutionary foundation for numerous eukaryotic immune strategies [2]. Experimental studies have validated many of these anti-phage defense systems and revealed the mechanisms by which they disrupt phage infection [3]. Nonetheless, major gaps persist in our understanding of how bacterial immune systems recognize bacteriophage infection to trigger immunity. This dissertation …

Suing The Ghost In The Medical Machine, Jason R. Cheek

SMU Science and Technology Law Review

Devices that autonomously diagnose medical conditions, with no human interaction, have arrived. These self-operating systems incorporate artificial intelligence (AI), and include machines that diagnose preventable blindness, as well as some that write radiology reports. These devices feature AI-integrated software to make diagnosis decisions traditionally made by humans who have received extensive medical training. Soon, AI-driven devices will autonomously make treatment decisions.

What happens when these autonomous medical systems harm a patient? At the moment, most would expect product liability law to provide a path to recovery. But AI oftentimes uses multiple complex inputs and approaches, including statistical probabilities, to reach …

Filling The Network Gap In Research Ethics: Analyzing Ethical Issues At Scale In Big Team Science, Susan Wolf, Gillian H. Roehrig, Timothy L. Pruett, Korkut Uygun, Claire Colby Mcvan, Evelyn Brister, Shawneequa L. Callier, Alexander M. Capron, James F. Childress, Rosario Isasi, Andrew D. Maynard, Kenneth A. Oye, Paul B. Thompson, Terrance R. Tiersch

Articles

Scientific research increasingly involves large, multidisciplinary teams networked across multiple institutions to develop new technologies. Despite the rise of complex research networks and big team science, there has been too little analysis to date of the ethical challenges facing these networks. The extensive literature on the ethical issues confronting individual researchers and small teams (the microlevel) and on the larger societal challenges flowing from research and new technology (the macrolevel) leaves a troubling gap in between, at the mesolevel of the research network involved in big team science. Yet the ability of complex networks to conduct research ethically—which is essential …

The purpose of this evidence-based quality improvement (EBQI) project was to evaluate whether implementing a structured, evidence-based nasal decolonization protocol improved staff compliance and reduced missed administrations and patient refusals among eligible medical-surgical inpatients.

Methods

This EBQI project was implemented on five inpatient medical-surgical units at a large academic medical center. Interventions included standardized staff education, …

Beyond The Bars: Reimagining The Dc Correctional System As The Frontline For Hepatitis C Elimination, Rahimatu Jalloh, Amber Munoz, Riyan Lee, Kristen Martinez, Malia Allen, Gerard Lin

DC Health and Academic Prep Program (DC HAPP)

Hepatitis C is a major public health concern among incarcerated populations, who are infected at rates approximately 10 times higher than the general U.S. population. In Washington, D.C., an estimated 12,700 people are living with hepatitis C, and the District has one of the highest HCV prevalence and mortality rates in the nation. Although hepatitis C is highly curable, many incarcerated individuals do not receive treatment despite having enough time to complete therapy while incarcerated.

This project proposes a comprehensive hepatitis C program for the D.C. prison system that addresses HCV through prevention, intake screening, treatment during incarceration, and post-release …
