Measures and stakes about the betweenness centrality of romantic partners in personal networks
Presenter: Prof. Claire Bidart (CNRS, France)
In this presentation, I will show that the position of the partner in personal networks is very diverse: at the center of the network or at the periphery, on the side of the family or on the side of friends... The length of time the couple has been together is of course a key factor, but not the only one. The dynamics of these networks, obtained through a longitudinal survey, allow to better understand these positionings. We will briefly discuss together the stakes involved in the structural indicator of betweenness centrality.
Claire Bidart is a sociologist, research director at CNRS in Aix en Provence, France. She has been working on the dynamics of personal networks and the life course. She designed and conducted a longitudinal survey, the "Panel of Caen", which followed over time the stages of entry into adult life of a population of young people re-interviewed every three years, between 1995 and 2015. The aim was to analyse the pathways and transitions to adulthood, to examine in detail the relational dynamics and changes in personal networks, and to explore the links between these different processes. Her works with Michel Grossetti and Alain Degenne have resulted in the publication of the book “Living in Networks: The Dynamics of Social Relations”, Cambridge University Press, 2020, as well as various exploratory works, in particular methodological ones. She is currently involved in a large longitudinal panel study on the impacts of the covid 19 pandemic and confinements on social, family and professional relationships.
Scientific cooperation dynamics in Svalbard: a core-periphery analysis
Presenter: Dr. Marion Maisonobe (CNRS, France)
In this presentation, I analyze the international cooperation network of scientific projects conducted in Svalbard (an archipelago located in the Arctic). This research allows to highlight the core-periphery structure of this network and its evolution.
Marion Maisonobe is a junior researcher in geography at the French National Centre for Scientific Research (CNRS). She studies the spatial diffusion of knowledge and the geography of flows, exchanges, and sociabilities at multiple scales. Using network analysis and information visualization methods, she seeks to make her approaches more accessible and reproducible. She is in charge of the development of the NETSCITY web application for mapping science data.
