This article explores the sources of self-rated health status inequalities among South Africans. We propose a decomposition of observed health disparities between racial groups using a procedure based on an extended version of Oaxaca-Blinder decomposition methods which addresses explicitly the specificities associated with the analysis of subjective measures. This method allows for a decomposit...

BACKGROUND The choice of sampling techniques in bronchoscopy with sampling from a visible lesion will depend on the expected diagnostic yields and the costs of the sampling techniques. AIMS The aim of this study was to determine the most economical combination of sampling techniques when approaching endobronchial visible lesions. METHODS A cost minimization analysis was performed. All bronc...

In this paper, a joint environmental and economic analysis of different Wastewater Treatment Plant (WWTP) control strategies is carried out. The assessment is based on the application of the Life Cycle Assessment (LCA) as a method to evaluate the environmental impact and the Benchmark Simulation Model No. 1 (BSM1). The BSM1 is taken as the benchmark scenario used to implement the control strate...
