Here are a few journal articles that might be useful that I found in a World History database called Historical Abstracts. The awesome thing about this database is that it isn't U.S.-centric: it includes articles published in foreign languages. However, my Spanish is pretty lousy, so I was guessing at some of these based on the subject descriptors. It would be a great database to search yourself, if you are still looking for resources.
So...this article is only partially relevant, but it was so interesting I could help but share it!
