 There's been an increase in the number of retractions. How can peer review play a role in this to arrest this trend? So I think the rate of retractions is not necessarily increasing but we are seeing more retractions for two reasons. One because the literature output is growing and two we're using different technologies or new technologies to be able to identify cases of largely where publication ethics have been flouted. I'm not sure that it's a burden reviewers can stand to police everything that they look at. I'm not sure that's the function of peer review to police it in that way and they have an obligation to look at the quality and the content of a manuscript for sure but as a couple of people have said to me on different occasions often peer review in the whole editorial process is really about trust so we have to be as publishers and as managing editors we have to be as watertight as we can be in our processes we have to we have to be careful about what we're looking at and we have to make sure we have tight processes in place. We have to make it easy for reviewers to be able to look at for example images to make sure that there's no clear evidence of image manipulation. We have to make sure that reviewers if they've got doubts about whether a paper has been page-rised and we give them the tools to be able to check that or we check it ourselves. Peer review is one thing and editorial governance is another thing and editorial control is another thing.
