teaching which is judged to be of the highest order of intellectual acumen and pedagogical effectiveness,
research which is recognized as outstanding by the national and/or international as well as local community of
scholars, and service which is regarded as exemplary in building the character of intellectual community at
Baylor. You can view the lecture presented by Dr. Rushing on October 1 by following this link:

you on our faculty!!!
The Action Plan for the Lerma-Chapala System Rescue (co-authored by Laura Dávalos-Lind) has been awarded
the Kasumigaura International Prize 2007. It was selected from among 234 plans for all over the world. The
award ceremony will be October 29 in Jaipur, India, during the XII World Lakes Congress.
