Because of its multidimensional nature, researchers have attempted to explain
social capital from various perspectives (Roxas, 2008). Nahapiet and Ghoshal
(1998) identified three dimensions of social capital: structural, relational, and
cognitive. The structural dimension refers to "the overall pattern of connections
between actors" (Nahapiet and Ghoshal, 1998, p.244) and focuses on impersonal
linkages among actors, such as network ties and network configurations
