BACKGROUND Global environmental health has emerged as a critical topic for environmental health researchers and practitioners. Estimates of the environmental contribution of total worldwide disease burden range from 25 to 33%. OBJECTIVE We reviewed grants funded by the National Institute of Environmental Health Sciences (NIEHS) during 2005-2007 to evaluate the costs and scientific composition...
Firms choose to seek environmental management system certifications such as ISO 14001 certifications for certain reasons. Since obtaining and maintaining such certifications is costly and also voluntary, firms are choosy in deciding which of their establishments are to be certified. In this paper we put forward a hypothesis that firms seek ISO 14001 certifications for their establishments when ...

To date, where it has been mostly used, it tends to deal with the relationships between environmental management and product supply chain and rarely focuses on the social dimension.

The local topography of a landscape can have a profound influence on airflow characteristics and cause modifications to broader synoptic scale winds. This paper reports the results of a preliminary field study examining the effects of a valley on wind velocity and direction. Anemometers and wind vanes were used to measure airflow characteristics upwind, within and downwind of a 20 m deep and 17...
