Cost estimation for solid waste management in industrialising regions--precedents, problems and prospects.

The importance of cost planning for solid waste management (SWM) in industrialising regions (IR) is not well recognised. The approaches used to estimate costs of SWM can broadly be classified into three categories - the unit cost method, benchmarking techniques and developing cost models using sub-approaches such as cost and production function analysis. These methods have been developed into computer programmes with varying functionality and utility.

Cost function analysis for solid waste management: a developing country experience.

The need for improved cost planning methods for solid waste management (SWM) is particularly strong in emerging economies where problems are severe, expectations for improvements are high, but finances are constrained. Estimating cost functions is suggested as an improved cost planning method. The research uses 1999 data from 298 Indian municipalities, covering over 140 million people.

Very low-dose risperidone in first-episode psychosis: a safe and effective way to initiate treatment.

Patients experiencing a first psychotic episode have high rates of extrapyramidal symptoms (EPSs) when treated with the doses of neuroleptics used in multiepisode or chronic schizophrenia. There is some evidence that lower doses may be equally, if not more, effective but less toxic in this population. Here, we report the results of a biphasic open label trial designed to assess the efficacy, safety, and tolerability of low-dose (2-4 mg/day) risperidone treatment in a group of 96 first-episode nonaffective psychosis patients.

A controlled trial of cognitively oriented psychotherapy for early psychosis (COPE) with four-year follow-up readmission data.

Objectives: Cognitively oriented psychotherapy for early psychosis (COPE) is aimed at facilitating the adjustment of the person, and preventing or alleviating secondary morbidity in the wake of the first psychotic episode. The present study reports on the outcomes of a controlled trial comparing two conditions: COPE versus No-COPE.

Method: Ninety-one people participated in the trial which was analysed by intention-to-treat, including 12 people who were assigned to COPE but refused to participate.
