Hi Christine. I am in Denver at the moment--exhausted having given 6 talks in 2 days and 2 last friday in Houston. I am happy to report that the Univ of Houston taped last week's talks with many such activities and it will soon be available in itunes and YouTube. I hope to share it in a couple of days. (Ke is working on her tenure and promotion file so she may not be posting this week and I am out of town--sorry for any delays in responding).
