It was a which I have done since 1999. It was a special pleasure to work with an outstanding team of volunteers---the editorial board, column editors, and others---and with the authors and reviewers, as well as with Mike Hamilton, managing editor, and the AAAI staff. As my administrative duties have expanded at Indiana University, where I am now executive associate dean of the School of Informatics and Computing, the time has come for me to pass the torch. The editorship provided me with a birdseye view of the field of AI that brought its stunning progress into focus. Research advances and the integration of AI into everyday life today give artificial intelligence unprecedented practical impact.

Now, 70 issues and 17 years later, I am still deeply grateful for the opportunity to contribute to AAAI and to the AI community through the editorship. It has been a privilege to guide the magazine's coverage and a treat to have the first look at exciting articles as they arrive. It has been an honor and pleasure to work with all those individuals -- worldwide -- whose efforts have made, and continue to make the magazine a success. It has been a joy to edit this magazine. However, now that my administrative role at Indiana University has grown, I realize that the time has come for me to pass the torch and allow new leadership to build on the magazine's many strengths.

The reports should address the following questions: 1. When and why did the competition start? How many times has the competition been held since its inception? How frequently is the competition held and is it colocated with other events?

In response, AI the poster's size, artistic constraints, Magazine has developed a poster to and diversity of perspectives, not all help educate students, faculty, and the suggestions could be included in the public about AI and to spur them to final design, but all were greatly appreciated. I also thank AAAI, the National The poster's design was based on Science Foundation, Microsoft input from experts on how to convey Research, and Yahoo!Research for their key aspects of AI and to capture the generous support. The are included at the poster web design does not attempt the impossible site, www.aaai.org/AILandscape.php. Nor does it present a list of new support of the poster project, especially advances, which would soon become Mike Hamilton, whose many contributions obsolete. Instead, it presents a snapshot played a key role throughout. of a few aspects of AI selected to catalyze interest and to prompt viewers The poster was designed by James to find out more by exploring AAAI Gary, of Brooklyn, New York.

The fourth Modeling and Reasoning in Context (MRC) workshop was held on August 20–21, 2007, in conjunction with the Sixth International and Interdisciplinary Conference on Modeling and Using Context, at Roskilde University, Denmark. This year’s workshop included a special track on the role of contextualization in human tasks (CHUT). The overall goal of the workshop was to further the understanding, development, and application of AI methods for context-sensitive information technology.
