Abstract
This paper explores the heterogeneous processes of social and technical change, and in particular the dynamics of techno-economic networks. It starts by considering the way in which actors and intermediaries are constituted and define one another within such networks in the course of translation. It then explores, first the way in which parts of such heterogeneous networks converge to create unified spaces linking incommensurable elements, and second how some of these links achieve longevity and tend to shape future processes of translation.
