Professor Ericsson has recently completed a book, entitled ”Samfunnets stebarn” (The Stepchildren of Society). By “stepchildren of society” is meant those children who are under the care of public or private institutions, and who for various reasons have been subjected to governmental control or hostility from their communities. “The Stepchildren of Society” consists of several independent chapters, all of which deals with how children have been perceived and treated over the last centuries. The representation is founded both on her own research as well as material by other researches working in this field.

The research group’s mandate is to promote research on prison camps and the treatement of prisoners during WWII.
