the Grange, Bruntsfield Links and the Meadows
Yup.
It's par for the course around the Meadows at this time of year. It's just a lack of risk assessment (aka common sense) among the new student population who arrive each autumn.
I read somewhere recently that the bit of your brain that does risk assessment and predicts consequences is one of the last bits to mature, often only into your twenties. Males are later than females. A bit of extrapolation from the medical research cast a great deal of doubt on the wisdom of letting people drive cars before the age of 21. I'll post a link if I find it.
Anyway - I personally take it as given that the (majority of) unlit, RLJing and dedicated pavement-cycling students are not being willfully antisocial or criminal; rather that they honestly just can't figure out by themselves the potential consequences without it being pointed out to them.
Logically, the time to do the pointing-out and set the expectations is when they arrive in town. On the face of it there would seem to be plenty of opportunities to get advice across, whether via freshers welcome packs and events, email, facebook, twitter etc etc. I don't know how much of this happens already but it would seem to be not enough or not being done effectively.
Regular reinforcement of the message is absolutely vital if it's to stick. One-off communications are ineffectual. One-off enforcement exercises also have a very short term effect, although I appreciate that the police have to work with the tools they are given.
Can anyone connected with the universities say what sort of advice is issued to the new students, either around cycling specifically, or as part of a broader safety / lawful behaviour advice piece?
