Q. I need references or current articles preferably no earlier than December of 2012, (although I would take whatever appears to be the most recent)

Hi Sarah, you'll probably have the best luck searching in the database, Web of Knowledge/Web of Science, and going to Google Scholar. I've created and attached a pdf with instructions to get you started. Here is a link to take you to Web of Knowledge:

If accessing it from off-campus, you'll be prompted to sign in with your library account. If you haven't set up/reset your library login yet, you will need to do that. I've also attached those instructions. If you have further questions please let me know. Have a great weekend!
