This seminar is the second part of the introduction to qualitative field methods in the social sciences that spans over two semesters. It is based on the assumption that the anthropology and sociology are not meant to discover a pre-existing object but construct their approach in a reflexive movement. Empirical techniques cannot be only acquired studying textbooks but need to be experienced concretely. Building on the main techniques discussed during the previous semester, participants will be asked to conduct a small fieldwork in the Geneva region. In relation to the topic selected, they will be encouraged to contact a variety of actors, including institutions (local associations, municipality and canton's offices, international or non government organizations, etc.). A particular attention will be given to reflexivity, to the way researchers negotiate their presence with their interlocutors and how this negotiation influence the information they collect. The seminar will favor discussions where participants will share their experience.
