Social and biological contagions are influenced by the spatial embeddedness of networks. Historically, many epidemics spread as a wave across part of the Earth’s surface; however, in modern contagions long-range edges—for example, due to airline transportation or communication media—allow clusters of a contagion to appear in distant locations. Here we study the spread of contagions on networks through a methodology grounded in topological data analysis and nonlinear dimension reduction. We construct ‘contagion maps’ that use multiple contagions on a network to map the nodes as a point cloud. By analysing the topology, geometry and dimensionality of manifold structure in such point clouds, we reveal insights to aid in the modelling, forecast and control of spreading processes. Our approach highlights contagion maps also as a viable tool for inferring low-dimensional structure in networks.

O Centro de Estudos de Comunicação e Linguagens é uma unidade de investigação da Faculdade de Ciências Sociais e Humanas da Universidade Nova de Lisboa (FCSH-UNL), existente desde 1983, que integra maioritariamente investigadores/docentes do Departamento de Ciências da Comunicação dessa faculdade, nomeadamente integrados nos cursos de Licenciatura, Mestrado e Doutoramento.
We are living in exponential times and the Internet of Things is the best example of this. We are moving from an Internet between humans to and Internet where billions, or in the next decade even trillions, of devices are communicating with each other. This requires a different infrastructure for the Internet, more security measures and global standards.
La revue tic&société est consacrée à l’analyse des rapports entre les technologies de l’information et de la communication (TIC) et la société. Nous sollicitons les textes dans lesquels l’analyse accordera une place centrale au social. Mais nous développons aussi un espace multidisciplinaire. C’est pourquoi nous sommes intéressés non seulement par les approches sociologiques mais également par les approches socio-économiques, sociopolitiques, sociocognitives, etc. Les contributions peuvent être, soit à dominante théorique, soit avoir un contenu principalement descriptif tout en comprenant dans ce deuxième cas une dimension analytique liée à un cadre théorique.
