Data analyzed in this presentation were collected under the auspices of the 2005-09 project, Women in Science and Engineering: Network Access, Participation, and Career Outcomes, a project funded by the National Science Foundation (Grant # REC-0529642).
Research Question:Research Question:
What type of networks provide more/better/right social capital?
Intuition: Entrepreneurial
Roots:Social capital literature:
◦ “investment in social relations with expected returns (Lin 2001)
Network literature:◦ Structural holes are source of social capital
(“early” Burt, 1992)◦ The content of social relationships is as
important in instrumental action as structure (Podolny and Baron, 1997)
◦ Right balance of open and close relationships in network (“late” Burt, 2001)
Individual networks that are rich in the structural holes (Burt, 1992, 2000, 2004, 2005)
Individual networks that consist of strong ties with individuals outside of ones organization (Higgins and Kram, 2001)
General model: Creation and Use of the Social General model: Creation and Use of the Social Capital (Adapted from Lin, 2001)Capital (Adapted from Lin, 2001)
Hypotheses: Hypotheses: Effects of Network PropertiesEffects of Network Properties
H1: Individuals with networks rich with structural holes will mobilize more social capitalNetworks that are rich in the structural holes are source of social capital (Burt, 1992, 2000, 2004, 2005)
H2: Individuals with networks rich with multiplex relationships will mobilize more social capital
Strong ties are source of social capital (Ibarra, 1995, Krackhardt, 1992, Nelson, 1989, Lin et al, 1981, among others)
Hypotheses: Hypotheses: Effects of Network PropertiesEffects of Network Properties
H3: Individuals with networks rich with multiplex relationships with unconnected alters will mobilize more social capital
In other words
H3: Individuals with entrepreneurial networks will mobilize more social capital
Hypotheses: Hypotheses: Effects of Network PropertiesEffects of Network Properties
H3a: Men with entrepreneurial networks with will mobilize more social (van Emmerik, 2006)
