Social Rhythms and Temporal Interference – Exploring Biographical Sequences of Calendars and Stories: The life course and transitions are structured by institutional and cultural frames that contribute to regulate the trajectories. From three similar longitudinal survey panels which were conducted in France, Quebec and Argentina, we can articulate different kinds of temporal data concerning the paths young people follow as they are entering adulthood. Their careers were noted month by month on calendars, and in-depth interviews were used to record their stories. A quantitative exploration of the sequences allows to compare the situations, the events but also their temporal coincidences, while a qualitative analysis of the stories allow to understand their precise arrangements and to compare the conceptions of change in these three countries. We explore the heuristic potential of such mixed-methods design for both international comparison and precise interactions between events and decisions.
