Core/periphery structure models: An alternative methodological proposal

The idea of a structure made up of a core and periphery is a common, classic paradigm in many fields of science. Following this line, in 1999, researchers Stephen Borgatti and Martin Everett developed a model of structural analysis based on the delimitation of a core formed by a group of densely connected actors, in contrast to a class of actors, more loosely connected and forming the periphery of the system.The original approach of these authors is modified, employing measures that, in our opinion, show a larger degree of coherence and accuracy in the proposed objectives.
