Multiple testing in spatial epidemiology: a Bayesian approach
… Mortality Ratios (SMR) collected in many spatial regions. A preliminary study on SMRs aims to formulate hypotheses to be investigated via individual epidemiological studies that avoid bias carried on by aggregated analyses. Starting from collecting disease counts and calculating expected …

Exploration of the spatial epidemiology of tick borne pathogens of livestock in Southern Cumbria
… of this thesis was to further understand the spatial distribution of questingIxodes ricinus ticks across farms in Southern Cumbria; as well as to attempt to understand theepidemiological and ecological factors that have a significant influence on the patterns of infectionsin livestock. This …

Spatial epidemiology of Rhodesian sleeping sickness in recently affected areas of central and eastern Uganda
… part of the recent disease focus extension. The spatial distribution of Rhodesian sleeping sickness was examined in Kaberamaido and Dokolo districts where the disease was first reported in 2004, using three different methodologies. A traditional one-step logistic regression analysis of disease …

Using GIS to evaluate the impact of the built environment on health in “Brown’s Farm” Philippi
This thesis uses a spatial epidemiology approach to investigate clusters of diseases across formal and informal built environments in "Brown’s Farm" Philippi. Health data were analysed using cluster detection methods in geographic information systems to identify diseases hotspots. The identified …

Computational, statistical and graph-theoretical methods for disease mapping and cluster detection
Epidemiology, the study of disease risk factors in populations, emerged between the 16th and 19th centuries in response to terrifying epidemics of infectious diseases such as yellow fever, cholera and bubonic plague. Traditional epidemiological studies have led to modifications in hygiene, diet, …

On Shape and Being Shaped - Rethinking the Urban Built Environment as a Catalyst of Childhood Inactivity and Obesity
… adopted, combining the strengths of quantitative spatial epidemiology and the qualitative exploration of children’s context-specific lifeworlds in London. The integration of findings obtained through these different research lenses showed that the built environment was severely implicated in …

Use of environmental variables to infer gene flow and population structure in the gopher tortoise (Gopherus polyphemus) and predict the seroprevalence of an emerging infectious disease
… from the field of landscape genetics to combine spatial genetic data with landscape data at both regional and local spatial scales to explore natural and anthropogenic landscape features that shape population structure and gene flow in a federally threatened reptile, Gopherus polyphemus. I also …

Statistical Predictions Based on Accelerated Degradation Data and Spatial Count Data
… We focus on applications from reliability and spatial epidemiology. Chapter 1 gives a general introduction of statistical predictions. Chapters 2 and 3 investigate the photodegradation of an organic coating, which is mainly caused by ultraviolet (UV) radiation but also affected by environmental …

Novel Applications of Geospatial Analysis in the Modeling of Infectious Diseases
… of geography and public health, the field of spatial epidemiology seeks to use the tools of geospatial analysis to answer questions about disease. In this work we explore two areas: the use of geostatistical modeling as an extension of niche modeling, and the use of mobility metrics to augment …

Improved estimates of risk of exposure to pathogens transmitted by mosquitoes
… reported in 2002. The state has seen significant spatial and temporal variation in WNV cases since then. The overall objective of this dissertation work was to improve our understanding of spatial variability of risk for transmission of WNV to humans. We exploited long-term data on mosquito …

Assessment of Socioeconomic and Environmental Factors for Diabetes Mellitus Prevention in San Bernardino County, California: Using Secondary Data and Geospatial Analysis
… cross-sectional ecological study used spatial epidemiology and secondary data analysis to assess the socio-economic and environmental factors influencing DM prevalence. The study aims to identify the key socioeconomic and environmental determinants and spatial distribution patterns of …

The Impact of Social Determinants of Health on Cardiometabolic Outcomes and Medication Adherence Among Vulnerable Populations in West Tennessee
… levels. The second study used a combination of spatial epidemiology and statistical analysis to identify and characterize census tract-level Hot and Cold spots of uncontrolled cardiometabolic conditions. Patient residence addresses were geocoded to census tracts using Esri ArcGIS Pro. Hot Spot …

Social evolution : opinions and behaviors in face-to-face networks
… for airborne contagious diseases (Elliott, Spatial Epidemiology, 2000). However, epidemiologists have not had access to tools to quantitatively measure the likelihood of contagion, as a function of contact/exposure with infected individuals, in realistic scenarios (Musher, NEJM, 2003), since …

Eco-epidemiology of West Nile virus in the midwestern United States
… infection, key associations derived from complex spatial epidemiology methods, and human activity and behavior risk. The O’Hara Ruiz lab was also among the first research groups to associate strong relationships between mosquito infection with temporal lags in precipitation and temperature. …

The variable contribution of larval habitats on the production of mosquitoes that transmit West Nile Virus: a landscape epidemiology approach
… areas. One part of the study region had a spatial and temporal correlation between larval mosquitoes and adult mosquitoes, but other places had high adult abundance without a clear indication of the larval habitat contributing to that increase. It is important to consider multiple types of …

The Emergence of Lyme Disease in Appalachia (2000-2019)
… in understanding the current and future spatial range and impacts of the continued emergence of Lyme disease in Appalachia. This study thus sought to examine the extent of the emergence of Lyme disease in Appalachia between 2000 and 2019 using spatial scan statistic. This type of analysis …

Examining the Relationship Between Safe Drinking Water Violations and Adverse Birth Outcomes in Virginia
The Safe Drinking Water Act (SDWA) was established to protect consumers from potential exposure to over 90 water contaminants. Each contaminant is assigned a health-based standard meant to reflect the maximum level at which an adverse human health outcome is unlikely; measurements beyond that level …

Computationally Efficient Specifications of Spatial Point Process Models and Spatio-Temporal Gaussian Models: Combining Remote Sensing Drivers with Geospatial Disease Case Data to Enhance Geographic Epidemiology
… are evaluated for use in analyzing large complex spatial and spatio-temporal data with the goal of contributing to an interdisciplinary effort of developing an eco-epidemiological model that quantifies the relationship between remotely sensed water quality and the incidence of ALS (Amyotrophic …

Examining the Modifiable Areal Unit Problem: Associations Between Surface Mining and Birth Outcomes in Central Appalachia at Multiple Spatial Scales
… MAUP is context-specific and analyzing multiple spatial scales may provide richer understandings of examined phenomena. More research is needed to understand the role of scale and areal unit in health-related analyses. This study examines associations between surface mining and birth outcomes …
