Far too often, there is a gap between research and policy and practice. Too much research is undertaken with little relevance to real life problems or its reported in ways that are obscure and impenetrable.

An accompanying paper describes an innovative programme in Canada to help bridge this gap. This commentary notes the growing acceptance of such initiatives but highlights the challenges of sustaining their benefits.
