Logic of change, change of logic

Just out: call for papers for the Prague International Colloquium Logic of change, change of logic. The colloquium is dedicated to formal approaches to attitude change. The aim is to bring together the different strands of research on the topic - whether they be logical or probabilistic, whether they deal with change of beliefs or desires or preferences etc. - with an eye to better understanding the philosophical and methodological challenges that change poses, and to getting a clear idea of where the field should be going.
