Peace Science Society (International) (PSSI)
With an emphasis on the "development of peace analysis and conflict
management," this society uses the works of both the social and
natural sciences. Membership and conference information is
available here, as well as abstracts to the Society's journal,
"Conflict Management and Peace Science." The "Journal of Conflict
Resolution" is also published under the auspices of PSSI. The PSSI
distributes selected data sets which may be of use to researchers.
Currently available data sets are: Interstate System Membership,
1816-1997; Militarized Interstate Dispute; Territorial Changes
Data, 1816-1996; and International Trade Data.
