Patterns of interdisciplinarity in science can be quantified through complementary dimensions. This paper studies as a case study the scientific environment of a generalist journal in Geography, Cybergeo, in order to introduce a novel methodology combining citation network analysis and semantic analysis. We collect a large corpus of around 200,000 ...
La supposée crise des politiques migratoires européennes depuis 1995, sa forte médiatisation et le besoin d’information de la société civile sur cette question éminemment politique ont contribué à une intense production cartographique des flux de migrants. L’accueil mitigé réservé à la carte de l’agence finlandaise Lucify sur l’exil syrien nous con...
Our goal is to establish a mathematical framework for the description of geographical distance in a comprehensive way. Geographical distance always refer to potential or realized movement between places, and these displacements obey the least effort rule. While this optimization of effort is well known to imply the Triangle Inequality in many situa...
Triangular inequality is one of the four mathematical properties of distance. Its respect derives from the optimal nature of the measurement of distance. This demonstration (L'Hostis 2016, 2017) reveals key aspects of distances and geographical spaces. We develop this argument by investigating the idea of the optimality of distance through a mathem...
Geographic routing has gained much attention as a basic routing primitive inwireless sensor networks due to its memory-less, scalability, efficiency and low overheadfeatures. Greedy forwarding is the simplest geographic routing scheme, it uses the distanceas a forwarding criterion. Nevertheless, it may suffer from communication holes, whereno next ...

Les campagnes des pays des Suds ont longtemps été étudiées au prisme de leur fonction productive. Toutefois, comme l’insécurité alimentaire ne relève pas seulement d’une question de production mais d’autres facteurs, tels que la vulnérabilité économique des populations (Sen, 1982) ou la circulation des denrées, Jean-Louis Chaléard a perçu les limit...
