This paper reports the results of a study to estimate a statistical health state valuation model for a revised version of the Health Utilities Index Mark 2, using Standard Gamble health state preference data. A sample of 51 health states were valued by a sample of the 198 members of the UK general population. Models are estimated for predicting health state valuations for all 8000 states defined by the revised HUI2. The recommended model produces logical and significant coefficients for all levels of all dimensions in the HUI2. These coefficients appear to be robust across model specifications. This model performs well in predicting the observed health state values within the valuation sample and for a separate validation sample of health states. However, there are concerns over large prediction errors for two health states in the valuation sample. These problems must be balanced against concerns over the validity of using the VAS based health state valuation data of the original HUI2 valuation model.
This study introduces a systems approach to malaria control. Comprising organizations from the health, environmental, agricultural, economic, political, and social sectors, the malaria control system (MCS) at hand is organized around a common goal of improving living conditions through reduced malaria. The premise is that effective malaria control strategies require the establishment of organizational linkages for information and knowledge flow in the MCS. The study first describes the systems approach. It then compares it with an existing cross-sector approach and identifies areas where the developed approach complements the existing ones. Lastly, it shows the application of the developed approach in the context of malaria control in Ghana.
The result of a general survey on the concentration of fall-out (239+240)Pu in soil collected from several regions in Iran are presented. The samples represent mixed soil averaged over the depth of 0-50 mm. According to the results obtained by alpha spectrometry on 96 soil samples from 32 locations, the (239+240)Pu concentrations vary in the range 80-360 mBq kg(-1). Under normal operating conditions and present counting setup, the minimum detectable activity (MDA) was approximately 8 mBq kg(-1) for soil samples.
