I just found this article about the World University Service of Canada which has been sponsoring refugees since 1978. The article is actually about the University of Victoria, where students contribute $.50 per semester to a scholarship that is offered every two years by UVic; a raise to $1.00 per semester would allow them to offer the scholarship each year.
Sounds like a model I should try and take to my university. I would also like to see faculty contribute $1-5, maybe $10-20, per year to such a scholarship fund. I wonder how such a proposal would be received?
