BACKGROUND Despite harmful drinking causing a significant burden on global health, there is a large treatment gap, especially in low- and middle-income countries. A major barrier to care is the lack of adequately skilled human resources to deliver contextually appropriate treatments. This paper describes the systematic process used to develop Counselling for Alcohol Problems (CAP), a brief psyc...

Small animals living in soils, called soil invertebrates, represent a very diverse group of inhabitants. They include earthworms, woodlice, spiders, springtails, mites, and some insects. Soil invertebrates feed on dead plants, fungi bacteria, or other invertebrates. The many ways interact with each other, the large number different species, make life soils complex difficult to understand. Unfor...

There is an extraordinary diversity in genetic systems across species, but this variation remains poorly understood. In part, this is because the mechanisms responsible for transitions between systems are often unknown. A recent hypothesis has suggested that conflict between hosts and endosymbiotic microorganisms over transmission could drive the transition from diplodiploidy to systems with ma...

This issue of PLoS Genetics contains the second of two important papers describing the high levels of meiotic failure caused by exposure of female mice to a chemical known as Bisphenol A (BPA) [1]. In the first article [2], Pat Hunt and her collaborators demonstrated high levels of meiotic failure in females exposed to BPA, suggesting that BPA exposure affects maturing oocytes. This conclusion ...

We construct an infinite horizon model of harmful addiction. Consumption is compulsive if it differs from what the individual would have chosen had commitment been available. A good is addictive if its consumption leads to more compulsive consumption of the same good. We analyze the welfare implications of drug policies and find that taxes on drugs decrease welfare while prohibitive policies ma...

At this time, when we have still some months to wait for the findings of the Royal Commission, it may be of interest to consider the certification of the lunatic. It is unfortunate that on this point (as on others) there is still a conflict between the ideas of the doctor?interested solely in the ultimate as well as the immediate mental and physical welfare of the patient?and various people int...
