One thing that I would really like to see us test out in Canada, which has been tried on campuses in the United States, is anonymous reporting mechanisms.
There is software available now that allows students to just simply go online, and from their dorm room, they can explain the circumstances of the assault and put in the name of the assailant. This information sits in a database, and the student will be notified if another student reports that she has also been assaulted by this person. In some interfaces, university security might have access to that information, but in an anonymous way, so that they can see the prevalence of incidents of sexual violence on campus without knowing names.
It's very simple, but I think it would go a long way to giving us a much better ability to capture the prevalence of sexual violence on campuses.
