Structural equation modeling in environmental risk assessment.

Structural equation modeling in environmental risk assessment.

Environmental epidemiology requires effective models that take individual observations of environmental factors and connect them into meaningful patterns. Single-factor relationships have given way to multivariable analyses; simple additive models have been augmented by multiplicative (logistic) models. Each of these steps has produced greater enlightenment and understanding. Models that allow ...

Structural equation models for meta-analysis in environmental risk assessment.

The potential of structural equation models for combining information from different studies in environmental epidemiology is explored. For illustration we synthesize data from two birth cohorts assessing the effects of prenatal exposure to methylmercury on childhood cognitive performance. One cohort was the largest by far, but a smaller cohort included superior assessment of the PCB exposure w...

Investigation of Socio-Economic and Environmental Effects of Taleghan Dam Using Structural Equation Modeling

Today water supply issue in large cities seems to be a big problem. This becomes more important with population growth and urbanization extension. To cope with this problem lots of irrigation and drainage projects have been implemented and operated that subsequently many socio- economic and cultural effects have been brought to the areas . The objective of the present study is to survey the soc...

Structural equation modeling the use of a risk assessment instrument in child protective services

Risk assessment instruments have been developed to help human service workers identify risk factors associated with abusive families. Many such instruments have been incorporated into management information systems in the form of Decision Support Systems (DSS). This paper reports findings from a case study that evaluated a risk assessment instrument as a decision support tool. Respondents consi...
