The research programme is structured by three levels on which transitions are formed across the different life ages: discourses, institutions and individuals. These levels provide different entries into the analysis of the production and formation of transitions. In a way they serve as different foci of research. At the same time not only the different levels as such but how transitions are formed in an interplay between these levels. Phd students choose conduct empirical research on one of these levels, the postdoc project aims at integration of data analysis on all thee levels. All together the research training group provides a space in which different approaches can be related to each other.
