Focuses on the typical phenomena associated with the hyperactive child-syndrome. Various aspects include a description of the syndrome at different ages, the prevalence of the syndrome, etiologies, drug treatment and its effects, and other forms of therapy. (SA)

A literary critic addresses science-oriented readers as an outsider and reviews the division between literature and the sciences. A common meeting point is seen in today's world in such broad concerns as environmental pollution. (MP)

A discussion is presented of future global energy supply and demand problems and two benchmark scenarios showing that time will be the limiting constraint in adapting the energy supply infrastructure to changing resource availability. (Author/SA).

Needs are expressed for the alleviation of world hunger and poverty including the accelerated development and application in each low-income country of a broad spectrum of technologies based on advances in the sciences. Emphasis is on agriculture, transportation and communications systems, and power grids. (Author/SA)

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)

This article focuses on opposition to a new law that orders Maryland's state-supported schools to bare intimate facts about their financial status to an ethics commission which makes all of the reports available to the general public. (Author/SA)

Discussed is the question of whether "heavy" neutrinos really do exist based on the evidence supplied by four research groups. The implications of its existence on the disciplines of particle physics, astrophsyics, and cosmology are discussed. Background information on the different types of neutrinos is provided. (KR)

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…

Reported is one researcher's efforts to solve a classic mathematical problem called the "sphere packing problem." The historical barriers to solving this geometry problem are discussed. (CW)

Discusses the problems posed for scientifically untrained judges and lawyers in ensuring the scientific validity of scientific evidence. Cites recent cases which indicate the results when courts do not hold expert witnesses to the standards and criteria of their own disciplines. (CW)

Reports on two longitudinal studies of two-year-old children who were extreme in the display of either behavioral restraint or spontaneity in unfamiliar contexts. Indicates that by age seven most of the restrained group were socially avoidant while the spontaneous children were talkative and interactive. (TW)

Looks at the impact of budgetary problems on the University of Michigan, indicating potential cuts in natural resources (33 percent), art (25 percent), and education (40 percent). Science/engineering departments, however, will benefit from reallocation of funds, since improvements in research equipment has been given a high priority. (JN)

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)

Included in this article is a discussion of operations research and systems analysis which attack large-scale problems and challenges other relevant sciences to unite with society to solve widespread social problems. (Author/SA)
