Strong and weak tie mechanics on small scale interactions apply to larger scale interactions on a structural level. For instance, they explain why some communities organize for common goals easily and effectively whereas others seem unable to mobilize resources. When facing a crisis of urban renewal which threatened to uproot their communities, the Italian community in Boston’s West End failed to stem this threat while the working class community Boston’s Charlestown. Communities in Boston’s West End were observed to be disconnected from each other in separate cliques where members rarely associated with members from outside groups whereas Charlestown’s communities where more interlinked via formal clubs and organizations of association where inter-group interaction was common. As a result, as information of the Boston’s urban renewal plans began to spread, Groups in the West End circulated the information among themselves, whereas in Charlestown, information disseminated more quickly through groups that were interconnected by association and leadership figures who were able to organize a response and a subsequent campaign to oppose the city’s plans.
