Professional activities.

The article presents information on several conferences and symposiums on computer programs. The National Science Foundation has awarded a grant of $50,500 for a Conference on Computers in the Undergraduate Curricula. It is intended to aid dissemination of plans and actual experiences in the use of computers in under graduate education, particularly in small two and four-year colleges. The Twelfth Annual Symposium on Switching and Automata Theory will be held in East Lansing, Michigan, on October 13-15, 1971. Papers are being sought, describing original research in general areas of switching theory, automata theory, and the theoretical aspects of computers, computation and programming.
