Once again I have finalized a course in Peace- and Conflict Studies. Through an assignment from The Department of Political Science, Umeå University, and in the framework of an international program for crisis- and conflictmanagement, I have been the teacher for students at a course on genocide, massviolence, crimes against humanity, international law and how modernity relates to these areas of concern. This only one example of courses in which I have been a teacher. I almost lost count of how many courses in this disciplin I have been a teacher in. Nevertheless, I feel it is life and death situation. Teachers can make a difference.
