Our method relies on the ability of the links to reduce the number of steps between two nodes in the network, which is measured by the number of shortest paths crossing each link, and its impact on the node proximity. In this way, we use node closeness to quantify the importance of a node inside its community. At the same time, we define a participation coefficient that depends on the shortest paths contained in the links that connect two communities. The combination of both parameters allows to identify the role played by the nodes in the network, following the same guidelines introduced by Guimer\u00e0 et al. [Guimer\u00e0 &amp; Amaral, 2005] but, in this case, considering global information about the network. Finally, we give some examples of the hub characterization in real networks and compare our results with the parameters most used in the literature. <\/jats:p>","DOI":"10.1142\/s0218127412501672","type":"journal-article","created":{"date-parts":[[2012,8,13]],"date-time":"2012-08-13T02:36:01Z","timestamp":1344825361000},"page":"1250167","source":"Crossref","is-referenced-by-count":0,"title":["NONLOCAL ANALYSIS OF MODULAR ROLES"],"prefix":"10.1142","volume":"22","author":[{"given":"J.
