The purpose of this scientific blog is to create a research network of researchers, clinicians and professionals working in the field of precariousness, exclusion and wandering (traumatic or pathological) and to maintain a thread of discussion between these practitioners and researchers. Our paradigm of the permanence in the precariousness are the living spaces conceived by F. Deligny, from which a form of bound, closer to images than to speech, can be possible. His theory of the camera associates us with contemporary research on technological mediations.The multidisciplinarity required in the approach to this form of suffering has led us to propose a seminar and a series of workshops bringing together researchers from the universities of Paris 13 (Sorbonne Paris Nord) and Paris 8. These seminars and workshops have been part since this year of the transversal axis of the Maison des Sciences de l'Homme Paris Nord (MSH PN).
