Propos haineux, cyberharcèlement, fausses informations, théories du complot, mais aussi manipulation des masses... Les réseaux sociaux sont aujourd'hui propices à tous les excès, à toutes les dérives. En une vingtaine d'années, ils se sont multipliés et occupent désormais une place prépondérante dans notre vie quotidienne.Cet ouvrage donne des clés simples pour comprendre la révolution qui a bouleversé nos existences. Du fonctionnement des algorithmes aux leviers de viralité, voici, en chiffres, en récits et en anecdotes, un panorama saisissant et accessible qui dit toute la vérité sur les plateformes, leurs dangers, mais aussi leurs bienfaits. Car les médias sociaux ont aussi permis l'émergence d'un cinquième pouvoir, après ceux de l'État et de la presse : celui de l'opinion publique.Alors, est-il trop tard pour revaloriser le partage, la solidarité, les liens sincères et féconds que peuvent procurer les réseaux ? Et surtout, ne faut-il pas, pour endiguer leurs dérives, parier sur l'intelligence collective plutôt que sur l'intelligence artificielle ?Décrivant ce monde, examinant les problèmes, suggérant les solutions, c'est en spécialiste que Véronique Reille-Soult offre ici un ouvrage complet, lucide et indispensable sur cet ultime pouvoir.

Cosmopolitics, an open-source dashboard designed by an Istat team to perform exploratory data analysis using Eurostat statistical open data on international trade, offers several tools for investigating globalization phenomena such as the dynamics of global value chains (GVC). The advantage of this widely spread economic organization is well known: companies obtain economic advantages by direct foreign investments or by production outsourcing, i.e. relocating some production phases to countries where high specialization or an advantageous labor market create greater opportunities. However, by its very nature, the GVC is highly sensitive to shock transmissions and supply chain disruptions associated with geopolitical events or epidemiological crises. The dashboard will be released as Istat experimental statistical product and available online. Through a Social Network Graph Analysis approach, it will offer students, researchers and policy makers the opportunity to explore the dynamics of global trade for specific products traded by different modes of transport. The tool allows users not only retracing recent critical phases affecting global trade, but also interactively simulating bilateral trade flows interruptions or closures of specific logistic poles or transport routes. This gives the opportunity to outline possible scenarios in which the GVC trade relationships reshape under shock transmissions, such as conflicts, changes in bilateral relationships between countries, logistics or transport new arrangements, reallocation of foreign investments, etc. By computing standard Social Network indicators (such as graph density, indegree, outdegree, and closeness centrality), the tool provides many quantitative measures associated with the specific global trade structures displayed. This paper will illustrate the methodology implemented in the dashboard and will provide examples on how to explore GVC scenarios by Cosmopolitics.

Community detection is one of the most important methodological fields of network science, and one which has attracted a significant amount of attention over the past decades. This area deals with the automated division of a network into fundamental building blocks, with the objective of providing a summary of its large-scale structure. Despite its importance and widespread adoption, there is a noticeable gap between what is arguably the state-of-the-art and the methods which are actually used in practice in a variety of fields. The Elements attempts to address this discrepancy by dividing existing methods according to whether they have a 'descriptive' or an 'inferential' goal. While descriptive methods find patterns in networks based on context-dependent notions of community structure, inferential methods articulate a precise generative model, and attempt to fit it to data. In this way, they are able to provide insights into formation mechanisms and separate structure from noise. This title is also available as open access on Cambridge Core.
