This Working paper on FUNCTIONAL BORDERS AND SUSTAINABLE SECURITY: INTEGRATING THE BALKANS IN THE EU AND THE EU- BALKAN RELATIONS consisted of elaborating the theoretical framework and of ensuring consistency in the theoretical background among the various workpackages. This involved a kick-off meeting that was organized in the first month of the project where the concepts of security and borders were discussed; in addition, the scope of each WP was more clearly defined. The State of the Art Report on the changing notion of borders and security was also published in an article form in the Journal on Southeast European and Black Sea Studies (Frank Cass, London) in January 2004.
