Dear Reader,This issue of the journal focuses on the question of bullying prevention, with a collection of articles put together by Manuel Eisner and Tina Malti. We are very grateful to them for the hard work they put in as focus section editors – and in their contributions to the section. The open section this time takes us to North America for a study of identity and in-group superiority and Africa for a review of the question of youth and violence.The next issue, to appear in spring 2013, will feature a double focus for the first time, presenting collections on transitional justice and on qualitative research on prejudices.December 2012Wilhelm Heitmeyer Douglas S.
