Evolution of social relationships between first-year students at middle school: from cliques to circles

Abstract People organize their social relationships under a restriction on the number that a single individual can maintain simultaneously (the so-called Dunbar’s number, ~150). Additionally, personal networks show a characteristic layered structure where each layer corresponds to relationships of d...
