I would like to thank the participants for comments and encouragement at conferences and workshops. In addition, feedback from both my supervisors, Tobias Karlsson and Erik Bengtsson, as well as from colleagues, especially Anders Nilsson, Malin Nilsson, and Mats Olsson, at departmental seminars have been most useful. I am also very grateful to the editors and referees for constructive feedback.
