Synthesis Of A Multimodal Ecological Model For Scalable, High-Resolution Arboviral Risk Prediction In Florida, Sean P. Beeman

USF Tampa Graduate Theses and Dissertations

West Nile virus (WNV) and Eastern Equine Encephalitis virus (EEEV) represent the two greatest endemic arboviral risks to the state of Florida. Currently, no approved human vaccine exists for the prevention of either virus. In the absence of a vaccine, effective disease surveillance is paramount for public health. In Florida, WNV and EEEV sentinel chicken surveillance is conducted by mosquito control programs operated at the county, municipality, or special taxing district level. This program was implemented in 1978 following human outbreaks of St. Louis Encephalitis virus (SLEV) that occurred between 1959 and 1977, with initial sentinel coops placed in proximity …

On The Importance Of Context: Examining The Applicability Of Infertility Insurance Mandates In The United States Using A Mixed-Methods Study Design, Nathanael B. Stanley

USF Tampa Graduate Theses and Dissertations

Accessibility of infertility services is disproportionately experienced in the United States. Although there exist state-based health insurance mandates for infertility services, these mandates contain language that disqualify people from using them. In order to better understand why these mandates are not able to reduce the financial burden and bridge the income disparity for using infertility services, the purpose of this study is to add context to the applicability of these insurance mandates through qualitative and quantitative inquiry. Using the Glass and McAtee model of risk regulators as an operational paradigm, this research explores the role of environmental context, or “place”, …

Mobile-Based Sidewalk Inventory App For Smart Communities, Health, And Safety, Madhav Erraguntla, Dursun Delen, Rupesh K. Agrawal, Karthic Madanagopal, Richard Mayer

Suburban Sustainability

As the United States and other nations strive to cope with the obesity epidemic (NCHS, 2015), progressive communities are developing sidewalk infrastructure to promote physical activity and health. The Center for Disease Control (CDC) recommends that community-based interventions like neighborhood walk, bike programs etc. have shown to be effective in promoting physical activity and health. Smart cities are embracing the development of community trails and promoting their use to increase physical activity among youth and adults. System implementation, data collection, and analysis were performed from January 2015 through July 2015. To promote these objectives, communities and cities need accurate information …

Identifying Nodes Of Transmission In Disease Diffusion Through Social Media, David Sebastian Lamb

USF Tampa Graduate Theses and Dissertations

The spread of infectious diseases can be described in terms of three interrelated components: interaction, movement, and scale. Transmission between individuals requires some form of interaction, which is dependent on the pathogen, to occur. Diseases spread through the movement of their hosts; they spread across many spatial scales from local neighborhoods to countries, or temporal scales from days to years, or periodic intervals. Prior research into the spread of disease have examined diffusion processes retrospectively at regional or country levels, or developed differential equation or simulation models of the dynamics of disease transmission. While some of the more recent models …

Applying Voronoi Tessellations As A Non-Orthogonal Grid Methodology To Inform Public-Private Mix Efforts In Nigeria: An Examination Of The Distribution Of Private Healthcare Providers In Six States And The Covariates Underlying Their Utilization, Trinadh Dontamsetti

USF Tampa Graduate Theses and Dissertations

TB care and prevention is led by the public sector, but many TB symptomatics first seek care in the private sector, highlighting the importance of engaging these facilities. This report examines basic TB epidemiology (such as the gap in case finding that could be addressed in part via private sector activities), health-seeking behaviors (HSB) and diagnostic delays, the size of the private sector, activities of professional societies, and financing. It examines the potential utility of integrating Voronoi tessellations as a GIS-based method for informing and improving Public-Private Mix (PPM) efforts throughout six states in Nigeria. Further, it explores a potential …

Federal Disaster Declarations And Denials: Analyzing Spatial Equity In The Implementation Of The Stafford Act, Richard Salkowe

USF Tampa Graduate Theses and Dissertations

Federal disaster declarations are authorized by the president under the provisions of the Robert T. Stafford Disaster Relief and Emergency Assistance Act of 1988. Prior studies have found varying levels of political influence associated with the declaration process. Factors including electoral votes, reelection years, congressional committee appointments, geographic location, and party favoritism have been implicated in claims of inequity associated with the distribution of federal disaster assistance. Compounding these concerns is evidence of recurring problems associated with disparities in the long-term recovery from disasters based on social and economic factors. This dissertation is a response to the call for further …

Eco-Epidemiology Of Eastern Equine Encephalitis Virus, Patrick Vander Kelen

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Eastern Equine Encephalitis virus (EEEV) is an alphavirus with high pathogenicity in both humans and horses. Florida continues to have the highest occurrence of human cases in the USA, with four fatalities recorded in 2010. Unlike other states, Florida supports year-round EEEV transmission. This research uses Geographic Information Science (GIS) to examine spatial patterns of documented sentinel seroconversions and horse cases in order to understand the relationships between habitat and transmission intensity of EEEV in Florida. Sentinel sites were categorized as enzootic, periodically enzootic, and negative based on the amount of chicken seroconversions to EEEV. Sentinel sites were analyzed …

Food Deserts' And 'Food Swamps' In Hillsborough County, Florida: Unequal Access To Supermarkets And Fast-Food Restaurants, Dana Beth Stein

USF Tampa Graduate Theses and Dissertations

Research has shown that the suburbanization of supermarkets has created `food deserts', defined as areas where socially disadvantaged individuals lack access to nutritious food outlets. Additionally, the growing presence of fast-food restaurants has created `food swamps', or areas where socially disadvantaged individuals encounter an overabundance of unhealthy food outlets. While previous studies have analyzed either `food deserts' or `food swamps' using conventional statistical techniques, a more comprehensive approach that includes samples of both healthy and unhealthy entities and considers the variety of available food options is necessary to improve our understanding of the local food environment and related disparities.
