Art for Social Change

Dissertation proposal first draft hot off the press. The gripping working title is:

To what extent can contemporary art act as a catalyst for social change, engage a community and engender a sense of identity?

I hope my tutor is as excited about it as I am! Will see this afternoon as I have a tutorial. @?!
POST UPDATE: Dissertation Proposal accepted. Dissertation here we come!!

So when I saw this it seemed relevant and thought I would post it here for future reference.
