Strong ties in a small world
This paper examines the celebrated ‘Strength of weak ties’ theory of Granovetter (1973). We examine two hypotheses implied by the theory: one, for any three players with two links present, the probability of a third link being present is increasing in the strength of the two ties, and two, the removal of a weak tie breaks more shortest paths than the removal of a strong tie. This paper tests th...
متن کاملTies, Weak and Strong
The members of every community can be thought of as linked by a network of one-to-one ties between people who are related to one another as friends, neighbors, relatives, or coworkers. The distance between any two people is the minimum number of steps through ties in the network needed to go from one to the other. A common and unusual characteristic of communities is that these distances are no...
متن کاملNetworks of strong ties
Social networks transmitting covert or sensitive information cannot use all ties for this purpose. Rather, they can only use a subset of ties that are strong enough to be “trusted”. This paper addresses whether is it still possible, under this restriction, for information to be transmitted widely and rapidly in social networks. We use transitivity as evidence of strong ties, requiring one or mo...
متن کاملThe Navigability of Strong Ties: Small Worlds, Tie Strength, and Network Topology Self-organization in Strong-tie Small Worlds
A small world (SW) is a (large) graph with both local clustering and, on average, short distances between nodes [1,2]. Short distances promote accessibility, whereas local clustering and redundancy of edges, as some research suggests [3,4], promotes robustness to disconnection and, through multiple independent pathways, reliable accessibility as well. For paths to transmit materials and informa...
