Contexts for academia

What contexts do folks involved in academia find work well? I divided my contexts into "Need brain" and "Don't need brain", but my "Need brain" group seems to need some additional granularity, but I can't quite figure out of what sort.

I've been considering a context that is basically "need at least an hour of uninterrupted time"--but it's rare for that context to actually arise when the term is in session.

Anyway, I was just curious what other people who are academics do in terms of contexts. (I have searched the forums and found some answers, but not quite the answer as to what people find works well)

Thanks
