The Personal and Community Relationships Laboratory (Laboratorio de Redes Personales y Comunidades) at the University of Seville has published a project that shows the structural properties of high-school students personal networks and predicts the probability of those students maintaining (or not) relationships with their high-school friends when they start their university studies. That is to say, the data obtained from individual personal networks can be used to predict positions in the complete networks. Specifically, having a less cohesive personal network (a more centralised one) means that the student is more open to new relationships.
