Nicolas Jullien is a professor of economics and management at IMT Atlantique. His primary research focuses on innovation management and the management of (virtual) organizations, as well as what is now known as “open innovation.” His work examines the interactions between market-based institutions and open, non-market collective production (such as open-source software and Wikipedia): how these collective productions impact the organization of these industries, both in terms of business models and the organization of work. N. Jullien is also interested in the governance of these digital commons from an institutional economics perspective, and in the impact of their institutionalization on their purpose, appeal, and organization.

Julie Denouël is a Senior Lecturer with the right to supervise research in Education and Training Sciences at the University of Rennes 2. Her research focuses on changes in education and training. More specifically, her work examines the transformations driven by public authorities since the late 2000s which, linked to objectives of innovation and change, form part of policies aimed at improving and modernising state institutions and services. Given these characteristics, the transformations are examined here as instruments of public policy, in terms of their content and the forms of regulation they entail, as well as their effects. The transformations are studied across three dimensions (digital, pedagogical and curricular) within two professional fields (vocational training and, above all, higher education).

Agnès Grimault-Leprince is a Professor of Sociology at the INSPE in Brittany. Her research examines the experiences of adolescents in leisure activities and at school. By situating her analysis within two spheres of activity that are often studied separately – school and leisure – she is able to account for the multiple socialising influences and the underlying logics that shape both young people’s current activities and their future aspirations. The primary aim is to gain a better understanding of the mechanisms within schools that reproduce social structures and gender hierarchies. This aspect of her work is particularly evident in her study of forms of ‘homework’, the demands and implications of which are interpreted very differently by adolescents, a fact which has a clear impact on their academic results. Alongside this ‘objective’ examination of academic rankings, her research also focuses on the subjective experience of school and leisure activities. It thus explores adolescents’ relationship with school and school culture, as well as with their leisure activities and social interactions. It examines the continuities and tensions experienced by adolescents between family culture, school culture and youth cultures, with a twofold focus: ‘finding one’s place’ within French society, where academic qualifications largely determine one’s social destiny; and ‘finding one’s place’ in the wider social world. Her work offers all those involved in education food for thought on how to achieve greater coherence between the school’s educational mission and the way the institution operates, and on how to better take into account the changing nature of adolescents’ development, which takes place largely outside school.
