Course à pied et consommation: le cas des coureurs genevois

Autrefois reléguée à l'intérieur des stades comme une discipline secondaire de l'athlétisme, la course à pied ne cesse, depuis les années 80, de se réinventer pour accueillir de nouveaux venus, jusqu'à en devenir la pratique populaire que l'on connaît aujourd'hui. Cet éclatement de la course à pied dite « libre », qui a l'avantage d'être un sport avec un coût de pratique relativement faible, a permis de toucher toutes les classes sociales. Parallèlement, le développement économique et touristique que connaît la course à pied donne aux coureurs, outre le statut de sportif, celui d'un consommateur. Dans ce contexte, cette étude adopte une approche socio-économique pour comprendre ce que consomment et ce qui influence la consommation des coureurs genevois dans leur pratique de la course à pied. La méthode qualitative, basée sur des entretiens individuels semi-directifs, a été choisie pour récolter les données sur la pratique, la consommation touristiques, le textile et le matériel, la nutrition, le coaching ou encore la consultation médicale et paramédicale.

Is blood still thicker than water? A life-course perspective on the transformation of family and friends' roles in personal networks

This thesis addresses the issue of the moving boundaries between family and friends' roles in personal networks, adopting a life-course perspective and using Switzerland as a case study. In a period of major changes in personal life happening in contemporary Western societies, understanding the organization of personal networks intertwined with the unfolding of individual life courses is of prime importance in facing new challenges with regard to social integration. The data stem from a representative national survey carried out in 2011 named Family tiMes, including 803 individuals born either in 1950-1955 or in 1970-1975. An innovative research design was adopted, combing cross-sectional ego-centered network data and retrospective longitudinal life-course data. The results show continuing boundaries between family and friends' roles and that family keeps a prominent role in personal networks despite the notable importance of friendship ties. One relationship stands out above all, that with the partner, followed quite a few steps behind by those with children. Regarding life courses, de-standardization tendencies were found in family formation and also a persistent gendering of occupational trajectories. Two kinds of life trajectories are particularly intertwined with personal networks, co-residence and partnership trajectories, both related to the unfolding of family life. In particular, transition to parenthood functions as a turning point in individuals' lives, deeply transforming their sociability. Finally, a twofold pluralization process was identified, affecting simultaneously the organization of personal networks and the unfolding of individual life courses. This thesis contributes to the literature on the sociology of family and personal life, and to fruitful interlinkage between the network approach and the life-course perspective.
