He has been a visiting professor in Peace Education in Heidelberg, at the University of Alberta, Edmonton, and at Gustavus Adolphus College in Minnesota, USA.
In the 1960s Pikas’ fields of teaching and research included cognitive psychology and in the 1970s Peace Education.
Since the 1980s, Pikas has been developing his Shared Concern method, SCm, originally aimed at dealing with cases of bullying and hazing when they occur in high school.
If this is considered to be acceptable by the therapeutic mediator, the probable victim is invited and a shared solution obtained.
If this is in accordance with the norms of the school, the case is considered to be solved but a surveillance continued until satisfactory co-operation is secured.
