abstract="A developed theory of social networks would potentially provide predictive and explanatory models for social processes at the most general level. The paper contributes to such a theory by elaborating one basic proposition: that social connections attract each other as a regular function of network parameters such as [`]structural strength' (number of common links) and [`]distance' (length of minimal path of linkage). The proposition is tested on longitudinal data from three locality-based networks.<p />",
