At the American Bar Association's annual conference in San Francisco, the Section on Dispute Resolution offers a number of sessions on August 10-11. Most interesting is a presentation on the U.S. Air Force's Negotiation Center of Excellence, which teaches interest-based, cross-cultural negotiation skills. Early bird registration closes May 31. (ABA Annual Conf. Info.; Section on Dispute Resolution.)
Note: The Negotiation Center of Excellence has a great website with lots of resources on facilitation and mediation. I'm adding a link from this page and my personal bookmarks.
