In his seminal work, Mark Granovetter (1973) challenged sociologists to test sociometric hypotheses regarding collective action in communitarian settings. In this article, we tested the two main hypotheses which consider social cohesion in communitarian urban settings-these being firstly cohesion by weak ties and secondly cohesion by multiplex ties. We studied the elite leaders of two slum communities of Belo Horizonte (Brazil). Three social processes were examined as multiplex interactions: recognized status, exchange of useful information and collaboration. Our findings reveal, on the one hand, that multiplexity is associated with the frequency of ties and, on the other, that reciprocity and shared domains of performance fuel such strong multiplexity. If we assume that elite connections conform to a high order structure, our findings, in contrast to previously well-established hypotheses, reveal a segmented social order in which multiplexity does not mean the overlapping of social circles. On the contrary, multiplexed social exchanges are restricted to specialized domains.
在他的开创性著作中，马克·格兰诺维特（Mark Granovetter）（1973 年）挑战社会学家去检验关于社区环境中集体行动的社交计量学假设。在本文中，我们检验了考虑社区城市环境中的社会凝聚力的两个主要假设——即弱关系的凝聚力和多重关系的凝聚力。我们研究了巴西贝洛奥里藏特的两个贫民窟社区的精英领袖。将三种社会过程作为多重互动进行了研究：公认的地位、有用信息的交换和合作。我们的发现一方面表明，多重性与关系的频率有关，另一方面表明互惠和共同的表现领域促进了这种强多重性。如果我们假设精英关系符合高级结构，那么与先前确立的假设相反，我们的发现揭示了一个分割的社会秩序，其中多重性并不意味着社会圈子的重叠。相反，多重社会交流仅限于专门的领域。
