What does "Associate Faculty" mean, as used for example in this job advert headlined
FACULTY AND ASSOCIATE FACULTY POSITIONS
and this brochure from the Perimeter Institute in Canada:
In just 11 years since the Institute’s inception, PI has grown to include: - 16 full-time Faculty - 15 Associate Faculty
Given the adjective 'full time' above, perhaps 'Associate' just means 'part-time', but I've never heard that usage before.
