    Abstract:

    A common data analysis setting consists of a collection of datasets of varying sizes that are all relevant to a particular scientific question, but which include different subsets of the relevant variables, presumably with some overlap. Here, we demonstrate that synthesizing cross-classified categorical datasets drawn from an incompletely cross-classified common population, where many of the sets are incomplete (i.e., one or more of the classification variables is unobserved), but at least on…

    Abstract:

    Aims Electroconvulsive Therapy (ECT) is a well-established and effective treatment in mood disorders but the use of ECT in Texas is much lower than the general average among the United States. Our goal is to explore the geographical accessibility of Electroconvulsive Services in Texas.

    Methods 22 ECT Centers in Texas listed in State’s 2016 annual ECT report were enrolled and georeferenced. We used Esri’s StreetMap Premium Network release 1 network dataset to generate 1-hour drive tim…

    Abstract:

    Research on racial residential segregation (RRS) and birth outcomes has focused on RRS at a broad geographic scale, in an aspatial framework, and in northern US cities. We developed a spatial measure of neighborhood level racial isolation of blacks. We examined the association between this new measure and low birthweight, preterm birth, and birthweight in the southern state of North Carolina. Natality data were obtained from the North Carolina Detailed Birth Record 1998–2002 files. Using mult…

    Abstract:

    Malaria and other vector-borne diseases represent a significant and growing burden in many tropical countries. Successfully addressing these threats will require policies that expand access to and use of existing control methods, such as insecticide-treated bed nets and artemesinin combination therapies for malaria, while weighing the costs and benefits of alternative approaches over time. This paper argues that decision analysis provides a valuable framework for formulating such policies and…

    Abstract:

    Background

    Veterans of the 1991 Gulf War have an increased risk of amyotrophic lateral sclerosis (ALS), but the etiology is unknown.

    Objectives

    This study sought to identify geographic areas with elevated risk for the later development of ALS among military personnel who served in the first Gulf War.

    Methods

    A unified geographic information system (GIS) was constructed to allow analysis of secondary data on troop movements in the 1991 Gulf War theatre in the Persian Gulf region including…

    Abstract:

    Environmental threats to children’s health are complex and multifaceted; consequently, children’s environmental health research strives to identify areas of elevated exposure, determine whether particular demographic groups are inequitably exposed, and link exposures to incidence of disease. Many environmental health researchers use geographic information systems (GIS) to ex post display the results of their data collection and analysis. This methodological paper shows some ways by wh…

    Abstract:

    In this study, we investigate the conclusions of a previous study by the authors regarding the competitiveness of waste-to-energy (WTE) technologies with data from Puerto Rico. Puerto Rico’s situation matches many of the conditions laid out in the earlier study and the island is currently seeking to modernize its energy production and waste management options. Examining production and environmental costs, we find that modern pollution control technology, high-energy production costs, and …

    Abstract:

    Background - Researchers and policymakers are increasingly focused on combined exposures to social and environmental stressors, especially given how often these stressors tend to co-locate. Such exposures are equally relevant in urban and rural areas and may accrue disproportionately to particular communities or specific subpopulations.

    Objectives-To estimate relationships between racial isolation (RI), a measure of the extent to which minority racial/ethnic group members are exposed to only…

    Abstract:

    Legacy environmental contaminants such as polybrominated diphenyl ethers (PBDEs) are widely detected in human tissues. However, few studies have measured PBDEs in placental tissues, and there are no reported measurements of 2,4,6-tribromophenol (2,4,6-TBP) in placental tissues. Measurements of these contaminants are important for understanding potential fetal exposures, as these compounds have been shown to alter thyroid hormone regulation in vitro and in vivo. In this study, we measured a su…

    Abstract:

    Despite the well-established adverse birth and childhood health outcomes associated with maternal smoking, smoking rates among pregnant women remain high. Psychosocial health attributes, including anxiety, depression, perceived stress, self-efficacy, and personality characteristics, have especially important roles in smoking behavior. Understanding who smokes during pregnancy and what factors influence this behavior choice may be key to improving the effectiveness of smoking cessation interve…

    Abstract:

    This paper addresses the current debate over the expansion of biomass-based fuels. Using full social cost analysis, we estimate production and environmental costs for various forest residue, coal, oil, and natural gas energy production systems, using Sweden as our case example. We aggregate and compare these costs to assess energy policy options. Our analysis indicates that while forest residues may constitute a reasonable replacement for coal, natural gas remains the dominant energy choice i…

    Abstract:

    Background - Although studies suggest that exposure to pollutants is associated with race/ethnicity and socio-economic status (SES), many studies are limited to the geographic regions where monitoring stations are located. Objectives - This study uses modeled predictive surfaces to examine the relationship between air pollution exposure, race/ethnicity, and measures of SES across the entire State of North Carolina. Methods - The daily predictions of particulate matter <2.5 µm in aerodynami…
