A Spatial Analysis of the Association Between Urban Heat and Coronary Heart Disease
Heart disease remains the leading cause of death in both the United States and globally. Urban heat is increasingly recognized as a significant public health challenge, particularly in its connection to cardiovascular conditions. This study, conducted in Jefferson County, Kentucky, examines the distribution of coronary heart disease rates and develops an urban heat risk index to examine underlying socioeconomic and environmental factors. We appli…
Externalizing behaviors in children living near coal-fired power plants
Based on our findings, fly ash may be a potential risk factor for externalizing behaviors in children living near coal-fired power plants. While a cross-sectional study design does not provide the opportunity to prove a causal relationship, it can generate hypotheses that inform more rigorous epidemiological studies for further investigation of the observed associations
Exploring Environmental Injustice in Exposure to Airborne Lead Released from Industrial Facilities in Kentucky, United States
Exposure to lead remains a critical public health concern due to its toxic nature and widespread distribution in the environment. Limited research has investigated the risks of lead emissions to the environment by many operating industrial facilities. Using geospatial analysis and multiple regression methods, this article examines racial and class inequalities in proximity to industrial facilities and the concomitant lead exposure. We observe sig…
Association Between Topsoil Lead Concentrations and the Risk of Violent Crime
Background: Childhood lead poisoning remains a critical public health problem in the United States. The neurotoxic effects of early life lead exposure have been associated with numerous behavioral issues, including violence. To explore this association further, we evaluated whether there was spatial association between topsoil lead levels and violent crime in Jefferson County, Kentucky. Methods: Our study collected topsoil samples from four pre-s…
Spatial Disparities in Coronavirus Incidence and Mortality in the United States
PURPOSE: This ecological analysis investigates the spatial patterns of the COVID-19 epidemic in the United States in relation to socioeconomic variables that characterize US counties. METHODS: Data on confirmed cases and deaths from COVID-19 for 2,814 US counties were obtained from Johns Hopkins University. We used Geographic Information Systems (GIS) to map the spatial aspects of this pandemic and investigate the disparities between metropolitan…
The Effects of Parental Absence on Children Development
Parental care in early childhood is viewed as one of the most important factors that help foster children's abilities. Using two nationally representative datasets collected in China, this paper examines the effects of parental absence on the short-term in-school outcomes and long-term educational achievement of left-behind children. The results show that parental absence is negatively associated with the development of left-behind children. Left…
Spatial dependence and spatial heterogeneity in the effects of immigration on home values and native flight in Louisville, Kentucky
This article examines how changes in foreign-born populations are associated with home values and native flight in Louisville, the largest city in Kentucky. In particular, we use spatial autoregressive models (SAR) to explore the spillover effects of foreign-born populations beyond neighborhood boundaries and utilize geographically weighted regression (GWR) to tackle spatial heterogeneity that is complicating the immigrant/neighborhood relationsh…
Contemporary patterns and issues of school segregation and white flight in U.S. metropolitan areas
Ovarian Cancer Incidence in the U.S. and Toxic Emissions from Pulp and Paper Plants
Ovarian cancer is the fifth leading cause of female cancer mortality in the U.S. and accounts for five percent of all cancer deaths among women. No environmental risk factors for ovarian cancer have been confirmed. We previously reported that ovarian cancer incidence rates at the state level were significantly correlated with the extent of pulp and paper manufacturing. We evaluated that association using county-level data and advanced geospatial …
School segregation in Jefferson County and the affiliated Louisville metropolitan area, USA
This article explores the spatiotemporal patterns of school segregation between blacks and whites in Jefferson County and its affiliated Louisville metropolitan area. The classical dissimilarity index and the GIS-oriented spatial segregation measure – S index are used to estimate school segregation based on public school enrollment data (1987–2008). Findings call for the significance of measuring school segregation from a metropolitan-wide perspe…
School Desegregation and White Flight Revisited
Recent studies on school choice have observed a continuing trend of white flight from urban public schools in response to the rising number of poor minority students. However, few researchers have investigated contemporary patterns of white flight in the context of school desegregation, even though a large number of school districts in the United States are still being integrated. This article explores the effects of school desegregation plans on…
