Processes of knowledge production and dissemination are increasingly set in an international context. In research and higher education the links between local actors and the international environments are both proliferating and intensifying. Individual level self-organised international collaboration is increasingly supplemented by national and supranational organised activities, and by market oriented activity with a global scope.
