Commuting from Lausanne to Geneva as usual, I read a very nice paper by Vincent Kauffman about the concept of motility:

this construct describes the potential and actual capacity of goods, information, or people to be mobile both geographically and socially. Three major features of motility – access, competence, and appropriation – are introduced. In this text, we focus on conceptual and theoretical contributions of motility. In addition, we suggest a number of possible empirical investigations.
