Television policy research and the social science community: An industry perspective.

Describes the activities of the Developmental and Social Research Unit at the American Broadcasting Companies. This unit consists of social scientists and other researchers, including psychologists and sociologists. They are responsible for (1) monitoring social trends in society, (2) conducting primary research to assess the impact of TV, (3) evaluating current research on the effects of TV and providing this information to management, and (4) serving as a liaison to the academic community. The author suggests that industry executives often find research results too theoretical for practical application. Suggestions are offered to academic researchers desiring to have their recommendations considered by the TV industry: (1) Emphasize unique research skills and capabilities not available in the industry; (2) develop innovative research techniques and methodologies; (3) use heterogeneous samples; (4) explore the industry's research needs; and (5) disseminate research findings as quickly as possible.

The ontogeny of long-term memory over the first year-and-a-half of life

This research documents the development of long-term memory in human infants from 2 months through the end of the first year-and-a-half of life. In the initial study phase, we trained 6- to 18-month-old human infants in an operant task and tested them after increasing delays until they exhibited no retention for 2 successive weeks. In the second phase, their data were combined with data previously obtained from 2- to 6-month-olds in an equivalent task. The resulting function revealed that the duration of retention increases monotonically between 2 and 18 months of age. This increase was not due to age differences in original learning. This is the first systematic analysis of the course of long-term memory across an extended period of infant development that is based on standardized parameters of training and testing. It provides a reference function against which measures of retention from infants of different ages that are obtained in different memory tasks with different parameters can be meaningfully compared.     

Cloning and characterization of a maize cDNA encoding phytoene desaturase, an enzyme of the carotenoid biosynthetic pathway

The work presents the results of researches of binding and degradation of 125I-Insulin by erythrocyte receptors in the patients with essential hypertension and healthy patients after glucose intake. In order to obtain full representation of the pattern of changes the serum IRI and glucose concentrations were assayed. Binding and degradation of 125I-Insulin by erythrocyte receptors were determined with the method described by Gambhir (1977), modified by the authors. The modification consisted in usage of constant concentrations of iodized insulin (0.9 pg/0.1 ml) and bovine insulin (2.4 I.U./0.1 ml). Before administration of glucose and in 30, 60 and 120 minutes after, venous blood was collected from ulnar vein. All examined persons were in sitting position during the trial of glucose intake. Obtained results show, that blood insulin level in the patients with essential hypertension is statistically significantly higher than in healthy persons of similar anthropometric characteristics. Binding of 125I-Insulin to erythrocyte receptors in fasting state is statistically significantly lower. Degradation after glucose intake in the patients shows decreasing tendency, while in healthy persons--growing tendency.
