U2 and social justice

Here's a 2006 senior honors thesis from Boston College called "When I Look at the World: Bono’s Transformation of Social Justice" (PDF). Contains a few errors, a bit of an odd organizational scheme, and general wide-eyedness, but it's a topic on which I haven't seen data gathered with quite this scope. Spanning U2's career (although the band is collapsed into Bono, unfortunately; in 121 pages there is one reference to Larry Mullen, 2 to Adam Clayton, and none to The Edge), it's a sort of catalog of U2-related social justice commitments as evidenced both in and outside of their music. There's a timeline of Bono's work for Africa which might be helpful to some folks.
