The paper analyses the scientific research production of more than a thousand faculty members of Louis Pasteur University, large and well ranked in Europe. We take account of individual and collective determinants to explain individual productivity in terms of intensity and quality. We find that individual variables related to the position occupied are… (More)
In this paper we present an original model of sequential problem choice within scientific communities. Disciplinary knowledge is accumulated in the form of a growing tree-like web of research areas. Knowledge production is sequential since the problems addressed generate new problems that may in turn be handled. This model allows us to study how the reward… (More)
Une approche bayésienne de l'identification des inventeurs dans les bases de données de brevets Résumé Cet article propose une méthode bayésienne pour traiter le problème de l'identification des personnes dans les grandes bases de données individuelles telles que les données de brevet. L'apport de cette méthode est mis en évidence à travers son application… (More)

In this paper, we present a model of 'collective innovation' built upon the network formation formalism. In our model, agents localized on a circle benefit from knowledge flows from other agents with whom they are directly or indirectly connected. They support costs for direct connections which are linearly increasing with geographic distance. The dynamic… (More)
This paper proposes a theory for establishing dominance relations between universities on the basis of their scientific production and the number of citations their publications received in given time window. We apply this theory to the ranking of French Universities.
This text discusses the approach adopted in a European research project concerning the relationships between science and industry. The analysis uses the notion of actors as vectors for the creation and diffusion of competences and knowledge throughout the innovation process. From this perspective, the article presents some results on the strategic behaviour… (More)
