Looking at mobility as a human right & opportunity for individuals and families, the aim is to promote a mutual and beneficial transfer of knowledge between Portugal and Italy, in order to enrich the theoretical framework on the ways different forms of family arrangements (nuclear, patrilinear, matrilinear, poligamic, monogamic, etc.) cope with and manage migratory processes, when one or some members migrate, especially in societies of southern Europe and the Mediterranean. The general aim of the team is to explore the impact of mobility on individuals' lives, considering family and household relationships, and taking into account how integration experiences are affected by gender representations and self-perceptions. In this project we will discuss the epistemological implications and choices involved in the methods of data collection in transnational mobility studies.The aim will be reached through the exchange among experienced and younger researchers, anchored in the work plan.
