Describes research which indicates that a number of peptide hormones act directly on the brain to affect learning and behavior. Investigations are currently being conducted to determine if these substances can be used to treat learning disorders or to improve the memories of normal people. (MLH)

Problems and opportunities for university scientists arising from their growing interaction with state and local governments are discussed. (DT)

Discusses relationships between the developed countries and the less developed countries. Emphasis is on the growing realization of the role of science and technology as determinants of standards of living. Widespread competence in geology is a positive factor. (Author/EB)

A Technology Delivery System (TDS) is used to explain the role of incentives in stimulating public use of solar energy. Summarizes the application, components, experimental verification, and agency responsibility for these incentives within the conceptual framework of TDS. (GS)

Provides a historical development of efforts to explain biological phenomena in terms of chemical substances present in living organisms. (MLH)

A brief summary. Topics include: solid crystals, nonlinear physics, collective phenomena, heavy-ion physics, astrophysics, and particle physics. (BB)

Results support the concept that perception of a missing fundamental is based on periodic neural activity. Suggests that the pitch of the missing fundamental is mediated by elements sensitive to frequencies other than those within the band of the masking noise. (Author/MA)

Provides findings of a study in which it was found that asymmetries in the size of the two feet were strongly related to sex and handedness; right-handed males having larger right feet and right-handed females having larger left feet, the reverse being seen in non-right-handed individuals. Differences were apparent in children even younger than…

Reports that amphetamine given to normal boys resulted in a marked decrease in motor activity and reaction time, and improved performance on cognitive test, a response similar to those observed in hyperactive children. (SL)

Reports increased central nervous system vigilance and activation was observed as indicated by pupillary dilation during the decision interval of a letter matching task as higher levels of processing were performed. (SL)

Reports the University of New York at Albany has been charged with violations of federal and state regulations for not obtaining approval of an ethics committee to conduct research on human subjects. (SL)

Reviews a study which sought to obtain a quantitative metabolic map of the neurons mediating a specific memory. Research results support notions of cooperative processes in which nonrandom behavior of high ensembles of neural elements mediates the integration and processing of information and the retrieval of memory. (ML)

Reports on the relationship of research activities, teaching effectiveness and rank of faculty members in seventeen academic departments at Carnegie-Mellon University. Results indicate teaching quality is unrelated to assignment and promotion and that research activity is strongly related to promotion. (JM)
