Some suggestions:

1) On links among types of actors in an industry, and consquences for both
the work that men and women do and ideas about gender:

        Bonnie H. Erickson, Patricia Albanese, adn Slobodan Drakulic.
2000. "Gender on a Jagged Edge: The Security Industry, its Clients, and
the Reproduction and Revision of Gender." Work and Occupations 27:
294-318.

2) I developed a gendered social capital item for the recent Canadian
federal election study and am working on a sries of papers. Keep an eye
out, these will be forthcoming.

Also look up Gwen Moore"s article in the ASR, based on the general social
survey of the US.
