BERKELEY - NOVEMBER 15: University of California, Berkeley students celebrate after again occupying campus as part of an 'open university' strike in solidarity with the Occupy Wall Street movement on November 15, 2011 in Berkeley, California.  Teach-outs, workshops, public readings, and marches will culminate in an attempt to re-establish an Occupy Cal encampment that was shut down by police last week. (Photo by Max Whittaker/Getty Images)
