An incorrect version of the article by Cole, Gregory, Arrieux, and Haran (Reference Cole, Gregory, Arrieux and Haran2017a) was initially published without approval from the lead author. As such, the original version has been retracted, and the correct version of the article has been published in this issue (Cole, Gregory, Arrieux, and Haran, Reference Cole, Gregory, Arrieux and Haran2017b). The original version has been updated to indicate the retraction, and the correct version is now the version of record.
Cambridge University Press and the Editor regret the oversight.
