This article investigates the influence of personal networks on changes of occupational rates of men and women becoming parents. It discusses and measures the effects of various interconnected dimensions of network structures and compositions, such as density, degree of overlap between partners' networks, geographical distance between network members, and types of relations (family, friendship, or others). A set of longitudinal analyses on 235 couples becoming parents in Switzerland shows that for women, higher density in emotional support triggers a reduction in occupational rates once the first child is born, while for men, a higher density in practical support is associated with an increase of occupational rates, with a resulting increase of gender inequalities in the division of paid labour. Results are valid both for intended changes and for changes observed in the transition, and they hold when controlling for parents' educational level, income and personal values about gender equality.

The broadcast diffusion of messages in Delay Tolerant Networks (DTNs) is heavily dependent on nodes mobility, since protocols must rely on contact opportunities among devices to diffuse data. This work is a first effort to study how the dynamics of nodes affect both the effectiveness of the broadcast protocols in diffusing data, and their efficiency in using the network resources. The paper describes three control mechanisms. The mechanisms characterize a family of protocols able to achieve some awareness about the surrounding environment, and to use this knowledge in order to keep the broadcast overhead low, while ensuring high node coverage. Simulation results identify the winning mechanisms to diffuse messages in DTNs under different conditions.

Cette étude esquisse, sur la base d'un grand échantillon représentatif et longitudinal de couples vivant en Suisse et du point de vue des femmes ayant répondu à l'enquête, un tableau de l'évolution des problèmes conjugaux rencontrés au cours des différentes phases de la vie familiale. Le processus de dégradation de la relation est reconstitué à partir de deux mesures faites dans un intervalle de 5 ans. La genèse des difficultés conjugales est considérée à travers le prisme des transitions familiales, en particulier la naissance des enfants, leur entrée à l'école et leur départ du domicile parental. L'analyse révèle le potentiel déstabilisateur de ces transitions pour le couple. Les bouleversements de l'équilibre relationnel évoluent, dans certains cas, vers un cumul de difficultés qui envahissent l'espace conjugal pour déboucher sur une situation inextricable.

Research on the trajectories of couples shows quite consistently that the birth of the first child leads to a transformation of the family structure towards a more traditional model whose key aspect seems to be the unilateral reduction of the professional insertion of women. The more or less egalitarian beliefs of the partners hardly seem to play a role. This interdisciplinary project aims to clarify why and how this transformation is taking place. It follows, in three waves, a panel of 300 couples for a year and a half, from the 4th or 5th month of the big until the age of 1 year of the child in the canton of Vaud.
