I do not understand the claim that this article does not cite any sources; it cites several well-respected and relevant peer-reviewed papers. This is my first major wiki contribution, so if I have made an error please point me to the relevant documentation and I will correct it. Eapache (talk) 20:17, 2 April 2014 (UTC)[reply]
