Abstract
Whatever the era, societies are built around and by movements that oscillate between preservation and development, leading them to major changes in their functioning in order to cope with the resulting social, demographic, cultural and economic impacts. The implementation of sometimes profound institutional reforms makes these movements observable, forcing actors to live, translate, interpret and incorporate these changes through adjustments, transitions or transformations in their professional and social practices. The aim of this issue is to bring together a set of contributions on institutional changes in relation to the evolution of a variety of education and training contexts (Belgium, Canada, France, Italy, Switzerland) within and through which translation processes take place. Working on the articulation between individual and collective logics and analysing more closely the processes of translation and the transactions that accompany them, the contributions will make it possible to grasp the effects of these changes both on the meanings and conceptions of work, but also on the professional and social practices that structure the relationships between the actors and objects of their translation.
