This paper entitled "Cooperative activities with space and time constraints: the case of a cafe-restaurant" by Béatrice Cahour and Barbara Pentimalli deals with the analysis of simple cooperative activities that occur in cafe-restaurant.

We analysed the cooperative activities between waitresses, waiters and cooks in a cafe-restaurant at lunch time, when the place is full of clients and the waiters hurry to get their orders produced in a reasonable time. They are then involved in individual activities but also in many collective communications and coordinations. These various interrelated "paths of action" have been videotaped and analysed with the help of actors' point of view; the analysis indicates the characteristics of the "minimized interactions" taking place in this situation of work, with lots of risks, few feedback signs and undetermined addressees necessitating peripheral awareness; it also indicates the characteristics of the "paths of action" with time and space constraints where strategies are used to avoid spatial movements (by using for example the colleagues' paths of action) and where the constant risk to collude a colleague get them to a subtile bodily synchronization.
