The Resilience Research Centre (Resilienceresearch.org).
Also there is a Coursera session from Dr. Ann Masten from the University of Minnesota on Resilience. The current course just finished but she will open the course again on Feb 2, 2015. I did the course that just finished and I liked all the supplemental information that was provided. The course is called: Resilience in Children Exposed to trauma, Distaster and War: Global Perspectives.
Oh the course isn't about resilience and aces per say but I still feel it is very relevant.
Hope that helps!!!
