One work which does employ Bourdieu's work in an enlightening way is that of Emirbayer & Williams (2005) who use Bourdieu's notion of fields and capital to examine the power relations in the field of social services, particularly homeless shelters. The authors talk of the two separate fields that operate in the same geographic location (the shelter) and the types of capital that are legitimate and valued in each. Specifically they show how homeless people can possess "staff-sanctioned capital" or "client-sanctioned capital" (2005:92) and show how in the shelter, they are both at the same time, desirable and undesirable, valued and disparaged, depending on which of the two fields they are operating in.
