The rules or laws come into place in January. There is going to be a campus climate survey piloted in 2017, with data in 2018. Students are being involved in the governance structure through helping to devise these policies. I think there is a lot of data to show that the first couple of weeks of school are the high-risk period, which you pointed out quite well.
Just as an aside, we do run ads and public awareness campaigns targeted at exactly that time, to make people aware that they are coming into new environments, what they call “frosh week”, and to make them aware of how to protect themselves.
