To determine how hard it is for computers to solve problems, researchers have classified groups of problems (polynomial hierarchy) according to how much time they seem to require for their solutions. A difficult and complex proof is offered which shows that a combinatorial approach (using Boolean circuits) may resolve the problem. (JN)

Discusses: (1) the synergistic nature of science, technology, and engineering; (2) the benefits and burdens of technology; (3) the resolution of societal issues; and (4) the roles and responsibilities of scientists and engineers in the resolution of societal issues. (JN)

Discusses an alternative approach to intelligence tests as a measure of intelligence. The approach is based on three classes of performance dealing with a person's choice of an internal representation for a problem, strategies for manipulating the representation, and abilities to execute elementary information processing steps required by the…

Discusses issues and problems related to the enhanced capability in science and technology. Areas addressed include opportunities and complications resulting from this capability, global interdependence, commitment to science education, and ways to foster cooperation between colleges and schools. (JN)

Discusses various aspects of artificial intelligence, focusing on three interrelated issues: (1) representation of knowledge, which is roughly the machine equivalent of human memory; (2) control and use of knowledge, which corresponds to human abilities in problem solving and planning; and (3) the acquisition of knowledge, or what humans call…

Presents the views of F. James Rutherford concerning the status of science education and his role as advisor on science education to the Board of Directors of the American Association for the Advancement of Science. (SK)

Describes Canada's International Development Research Centre (IDRC), an independent public corporation established to aid scientific research in developing nations. The four programs executed by them are agriculture, food, and nutrition sciences, health sciences, information sciences, and social sciences. (Author/SA)

Describes the federal reporting requirements of faculty time on federally sponsored research projects, their context, uses made of the figures, and reasons advanced for objecting to such reports. (Author/SK)
