The study of disciplines has a long tradition, but it has often mainly focused on scientific activities. With a few exceptions (Clark 1987; Bertrand 1993; Bertrand et al. 1994; Schimank 1995), the interplay between different tasks is ignored and when it is not, attention has generally focused on the teaching-research divide. In the research presented here, we decided to take a look at “academic work” in all its various dimensions, i.e., at all the activities faculty members are involved in: teaching, research, administrative tasks, consultancy, doctoral training, professional training, etc. Four disciplines were explored for this purpose in French universities: history, business studies, biology, and physics.
