By the friendly support of the ZEIT-Stiftung PRIF was able to invite guests from the co-operating Peace Studies Program (PSP) of Cornell University at Ithaca (NY) to PRIF’s annual conference to Frankfurt in October 2005. For three days, the researchers of both institutes presented their theses to each other and discussed them. Those presentations have been elaborated into Occassional Papers which can be downloaded free of charge from the web site of the Peace Studies Program. Among that papers are those from PRIF researchers Claudia Baumgart, Thorsten Gromes, Pamela Jawad, Peter Kreuzer, and Heidrun Zinecker.
