Here is a blurb about USC from another forum - it may answer some questions about their weird ways
Back in the late 60s/early 70s, the then-president of the UC system Sproul went along with the then-GE model of doing business, which was to split everything up into semi-autonomous spheres in order to allow creativity and localized attention (a very 60s idea that was popular in lots of industry settings). The problem is that he did it wrong and never made communication lines running through these spheres to the top, and today most UCs are fractured bureaucratic fiefdoms with no one answering to anyone else.
As a result, there is no consistent answer to any question about UC schools, or even departments within particular schools. My department (not a natural science, either) has enough money from endowed chairs and federal grants to be doing just fine, ignoring the mandatory staff firings, hiring several faculty last year, and keeping grad numbers up. Other departments are facing 50% cuts in funding by next year, with staff cuts, hiring freezes, and sharply cut enrollments.
