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

re: Contexts in Academia

The "no-brain" vs. "lots of brain" distinction has more to do with energy and time than it does to do with location. David Allen recommends a schema of

Location --> Time --> Energy --> Priority

So it's best to keep your location contexts as physical places you need to be located to get things done -- e.g. Home, Office, Library, School, etc.

And you can specify the rest in a format that suits you. For me, I use the following:

@ Library(<30min): Look up and read the first chapter in this book for class X.

If you need to specify energy or priority, you can do that too:

@ Home(<60min-High Energy): ?

etc.

Hope that helps.
