Here’s a story in the Davis Enterprise about UC-Davis disinviting Larry Summers as a speaker to the regents.

An excerpt:

UCD professor Maureen Stanton, one of the petition organizers, was delighted by news of the change this morning, saying it’s “a move in the right direction.”“UC has an enormous historical commitment to diversity within its faculty ranks, but still has a long way to go before our faculty adequately represent the diversity of our constituency, the people of California,” said Stanton, professor and chairwoman of the section of evolution and ecology.
When Stanton heard about the initial invitation to Summers, she was “stunned.”
“I was appalled that someone articulating that point of view would be invited by the regents,” she said. “This is a symbolic invitation and a symbolic measure that I believe sends the wrong message about the University of California and its cultural principles.”
Stanton and other women on campus began circulating a petition Tuesday night by e-mail to colleagues at several campuses in the UC system. In two days, they had collected more than 150 signatures.
