Traffic-related air pollution (TRAP) may affect immune responses, including those in the TH2 and TH17 pathways. To examine whether TRAP is associated with plasma level of TH17-, TH1-, and TH2-related cytokines in children with and without asthma, a cross-sectional study of 577 children (ages 6-14 years) with (n = 294) and without (n = 283) asthma in San Juan (Puerto Rico) was performed. Residen...

Background. Proximity to heavy traffic has been linked to increased asthma severity. However, it is unknown whether exposure to heavy traffic is associated with the ability to maintain asthma control. Objectives. This study examines whether exposure to heavy traffic is associated with the ability to maintain asthma control in inner-city children. Methods. 756 inner-city asthmatic Hispanic child...

This study examined the impact of two different detention basin designs on residential property value. The hedonic price model was applied to analyze two College Station, TX, subdivisions. One subdivision had only uniuse flood control detention basins (UDBs) and the other included amulti-use detention basin (MDB) integrating a detention pond with a recreational neighborhood park. Geographic inf...

In this paper we focus on gaining insight into the residential satisfaction of households near highways, based on survey data collected among 1,225 respondents in the Netherlands living within 1,000 meters from a highway. Ordinal regression was used to study the impact of highway externalities on residential satisfaction. Moreover, we gained first insights into the reactions of people on highwa...

As a consequence of the ongoing growth in demand for houses in the Netherlands over recent decades, the fraction of the total surface used for residential purposes has expanded rapidly. The location patterns of new residential construction are the result of various forces: government intervention aiming at the preservation of open space via zoning, new-town, and `compact-city' policies, and mar...

Geographically weighted regression (GWR) enjoys wide application in regional science, thanks to its relatively straightforward formulation and explicit treatment of spatial effects. However, its application to discrete-response data sets and land use change at the level of urban parcels has remained a novelty. This work combines logit specifications with GWR techniques to anticipate five catego...

A retrospective population-based case-control interview study has been conducted in three distinct areas in the north of England where local excesses of children with leukaemia have been reported. A total of 109 cases of childhood (0-14years at diagnosis) leukaemia and non-Hodgkin's lymphoma who were born in one of the study areas and diagnosed there between 1974 and 1988 were included in the s...

In developing countries, rapid industrialization without environmental controls has resulted in heavy metal contamination of communities. We hypothesized that residential neighborhoods located near ore industries in three northern Mexican cities would be heavily polluted with multiple contaminants (arsenic, cadmium, and lead) and that these sites would be point sources for the heavy metals. To ...
