Humidity Reduces Rapid And Distant Airborne Dispersal Of Viable Viral Particles In Classroom Settings, Antun Skanata, Fabrizio Spagnolo, Molly Metz, Davida S. Smyth, John J. Dennehy

Publications and Research

The transmission of airborne pathogens is considered to be the main route through which a number of known and emerging respiratory diseases infect their hosts. While physical distancing and mask wearing may help mitigate short-range transmission, the extent of long-range transmission in closed spaces where a pathogen remains suspended in the air remains unknown. We have developed a method to detect viable virus particles by using an aerosolized bacteriophage Phi6 in combination with its host Pseudomonas phaseolicola, which when seeded on agar plates acts as a virus detector that can be placed at a range of distances away from an …

Lyddon, Michelle Markman, Clayton Rushford, Kaung Myat San, Geena Sompanya, Fabrizio Spagnolo, Reinier Suarez, Emma Teixeiro, Mark Daniels, Marc C. Johnson, John J. Dennehy

Publications and Research

Tracking SARS-CoV-2 genetic diversity is strongly indicated because diversifying selection may lead to the emergence of novel variants resistant to naturally acquired or vaccine-induced immunity. To monitor New York City (NYC) for the presence of novel variants, we deep sequence most of the receptor binding domain coding sequence of the S protein of SARS-CoV-2 isolated from the New York City wastewater. Here we report detecting increasing frequencies of novel cryptic SARS-CoV-2 lineages not recognized in GISAID’s EpiCoV database. These lineages contain mutations that had been rarely observed in clinical samples, including Q493K, Q498Y, E484A, and T572N and share many mutations …

Health Department Prevention/Education Plans And Perceived Risks Of Zika Infection, Lacey Jacques

Walden Dissertations and Doctoral Studies

AbstractZika virus is an infectious disease caused by the bite of an infected mosquito that has been linked to increased rates of microcephaly and other devastating birth defects. The existing body of knowledge has focused on the individual-level factors that influence a person’s decisions about prevention activities and risk perceptions related to Zika virus. The purpose of this study was to determine the relationship between state-level plans for prevention and education and individual-level risk perceptions. Rosenstock’s health belief model lays a foundation for why individuals make the health decisions they do and helps explain how these can be influenced for …

Perceptions Of Implicit Bias In New York City Healthcare System During Covid-19, Kiesha Jackson

Walden Dissertations and Doctoral Studies

Implicit bias has been identified as a significant problem that hinders effective healthcare delivery. The purpose of this qualitative exploratory phenomenological study was to examine whether implicit bias influenced healthcare services for African Americans with comorbidities aged 30 and over living in New York City during the COVID-19 pandemic. Current studies show healthcare disparities, revealing barriers with healthcare delivery; however, they do not disclose a patient’s lived experience qualitatively, which constituted a gap in the literature. The frameworks of the behavioral model of health services use, and social construction and policy design guided this study. Research questions addressed (a) whether …

Attitudes Of State Public Health Laboratory Directors Towards Iso/Iec 17025 Accreditation, Christine Kilonzo

Walden Dissertations and Doctoral Studies

The impact of ISO/IEC 17025 accreditation in state public health laboratories (SPHLs) is understudied. There is a scarcity of research on SPHLs involving behavioral intent regarding ISO/IEC 17025 accreditation. The theory of planned behavior (TPB) was utilized to evaluate SPHL directors’ attitudes towards and intent to seek or maintain ISO/IEC 17025 accreditation. To test the questions of whether the three constructs of the TPB, attitude, subjective norms and perceived behavioral control are significant predictors of intent to seek or maintain ISO/IEC 17025 accreditation, and whether there are significant differences in these constructs towards the accreditation between SPHL directors based on …

Eng, David Shipman, Emma S. Mcbryde, Michael T. Meehan, Jamie M. Caldwell, James M. Trauer

Mathematics Faculty Publications

Mathematical models that capture COVID-19 dynamics have supported public health responses and policy development since the beginning of the pandemic, yet there is limited discourse to describe features of an optimal modelling platform to support policy decisions or how modellers and policy makers have engaged with each other. Here, we outline how we used a modelling software platform to support public health decision making for the COVID-19 response in the Western Pacific Region (WPR) countries of the Philippines, Malaysia and Viet Nam. This perspective describes an approach to support evidence-based public health decisions and policy, which may help inform other …

An Examination Of Three Transitional Events In The Substance Misuse Trajectories Of Women With Criminal Legal System Involvement, Martha Tillson

Theses and Dissertations--Sociology

Research has consistently demonstrated that criminal legal system (CLS)-involved women are distinct from men in initiation and course of drug use, with important differences on biological, environmental, and sociocultural levels. Thus, the unique pathways and transitions into and out of drug use for women with CLS involvement are critical to consider from a research perspective, but also from a need to develop and support evidence-based, women-centered services in correctional contexts. This dissertation project uses a three-paper format to investigate three aims: (1) to understand CLS-involved women’s initiations to injection drug use and their experiences providing injection initiation assistance (IIA) to …

Covid-19 Vaccination In Palestine/Israel: Citizenship, Capitalism, And The Logic Of Elimination, Nicolas Howard, Emily Schneider

Sociology & Criminal Justice Faculty Publications

Despite Israel’s responsibility under international law to combat the spread of contagious diseases and epidemics in its occupied territories, Israeli officials have refused to distribute COVID-19 vaccines to Palestinians in the West Bank and Gaza Strip. Through a critical discourse analysis of Israeli officials’ statements regarding Israel’s COVID-19 vaccination campaign, this paper explores how Israel evades this responsibility while presenting itself as committed to public health and human rights. We find that Israeli officials strategically present Palestinians as an autonomous nation when discussing COVID-19 vaccinations, despite Israel’s ongoing attempts to prevent the creation of a Palestinian state. Relatedly, Israel justifies …

Unpacking The Influence Of Islamic Religious Culture And Individual Religious Affiliation On Testing Hiv-Positive, Brittany Hayes, Amy Adamczyk

Publications and Research

The distribution of HIV cases varies cross-nationally. We separate the influences of Islam at the macro-and micro-levels to understand the role of religion in shaping the spread of HIV. Drawing on biomarker data from the Demographic and Health Surveys, we construct a multilevel database (Individual N= 568,476; Country N= 30). We examine a series of national-and individual-level predictors that may mediate the relationship between Islam and testing HIV-positive. Individual religious affiliation and proportion Muslim retained their risk-reducing effects even when accounting for a range of mediators and suppressors. Islam has a sui generis effect on testing HIV-positive.

Research outputs 2014 to 2021

Background: Collation of aphasia research data across settings, countries and study designs using big data principles will support analyses across different language modalities, levels of impairment, and therapy interventions in this heterogeneous population. Big data approaches in aphasia research may support vital analyses, which are unachievable within individual trial datasets. However, we lack insight into the requirements for a systematically created database, the feasibility and challenges and potential utility of the type of data collated. Aim: To report the development, preparation and establishment of an internationally agreed aphasia after stroke research database of individual participant data (IPD) to facilitate planned …

Examining Cognitive Empathy Elements Within Ai Chatbots For Healthcare Systems, Lamia Alam

Dissertations, Master's Theses and Master's Reports

Empathy is an essential part of communication in healthcare. It is a multidimensional concept and the two key dimensions: emotional and cognitive empathy allow clinicians to understand a patient’s situation, reasoning, and feelings clearly (Mercer and Reynolds, 2002). As artificial intelligence (AI) is increasingly being used in healthcare for many routine tasks, accurate diagnoses, and complex treatment plans, it is becoming more crucial to incorporate clinical empathy into patient-faced AI systems. Unless patients perceive that the AI is understanding their situation, the communication between patient and AI may not sustain efficiently. AI may not really exhibit any emotional empathy at …

Examining Psychological And Knowledge Barriers To Colorectal Cancer Screening In Rural Appalachian Kentucky, Caroline Jenkins, Matthew Rutledge, Lauren Hudson, Nathan L. Vanderford, Nancy Schoenberg

Markey Cancer Center Faculty Publications

While recent rates of colorectal cancer (CRC) screening have improved in Appalachian Kentucky due to public health efforts, they remain lower compared to both KY as a whole, and the USA. Suboptimal screening rates represent a missed opportunity to engage in early detection and prevention. The purpose of this study is to determine the impact that lack of knowledge has on psychological barriers (e.g., fear and embarrassment) to CRC screening as well as the potential effect of a psychosocial intervention to reduce these barriers. Participants were recruited through faith-based organizations and other community sites. After randomizing participants to either an …

Circling The Drain: The Extinction Crisis And The Future Of Humanity, Rodolfo Dirzo, Gerardo Ceballos, Paul R. Ehrlich

Harold W. Manter Laboratory of Parasitology: Library Materials

Humanity has triggered the sixth mass extinction episode since the beginning of the Phanerozoic. The complexity of this extinction crisis is centered on the intersection of two complex adaptive systems: human culture and ecosystem functioning, although the significance of this intersection is not properly appreciated. Human beings are part of biodiversity and elements in a global ecosystem. Civilization, and perhaps even the fate of our species, is utterly dependent on that ecosystem’s proper functioning, which society is increasingly degrading. The crisis seems rooted in three factors. First, relatively few people globally are aware of its existence. Second, most people who …

Rural Parent's Experiences Of Stress And Resilience During The Covid-19 Pandemic And School Closure, Emily Wilson, Jungwon Eum, Yuenjung Joo, Martinique A. Sealy, Jentry Stoneman Barrett, Gwen C. Nugent, Joan M. Carraher, Angela G. Hinrichs

Department of Child, Youth, and Family Studies: Faculty Publications

The COVID-19 pandemic has generated social and economic disruptions, resulting in cascading effects on the health and well- being of global citizens. However, little research has focused on how COVID-19 has affected rural regions, despite rurality being a critical factor for understanding community impact and response to the pandemic. The purpose of this phenomenological study was to explore the experiences of rural Nebraskan parents with young children during the COVID-19 pandemic and school shutdown, and the strategies they used to support their families during that time. We conducted individual and group interviews with 22 white, non-Hispanic mothers living in rural …

The 1990s saw the rapid reemergence of malaria in Amazonia, where it remains an important public health priority in South America. The Amazonian International Center of Excellence in Malaria Research (ICEMR) was designed to take a multidisciplinary approach toward identifying novel malaria control and elimination strategies. Based on geographically and epidemiologically distinct sites in the Northeastern Peruvian and Western Brazilian Amazon regions, synergistic projects integrate malaria epidemiology, vector biology, and immunology. The Amazonian ICEMR’s overarching goal is to understand how human behavior and other sociodemographic features of human reservoirs of transmission— predominantly asymptomatically parasitemic people—interact with the major Amazonian malaria …

Identification Of Biomarkers For The Prediction Of Radiation Toxicity In Prostate Cancer Patients, Daniel Cullen

Doctoral

The success of radiotherapy in tumour control depends on the total dose given. However, the tolerance of the normal tissues surrounding the tumour limits this dose. It is not known why some patients develop radiation toxicity and, currently, it is not possible to predict before treatment which patients will experience adverse effects. Thus, there is an unmet clinical need for a new test to identify patients at risk of radiation toxicity. The aim of this study was to determine if spectral variations in blood lymphocytes from PCa patients may suggest Raman spectral bands that could be used in future research …
