Recent experience of the application of a commercial data base management system (ADABAS) to a scientific data bank (ECDIN)     

William G. Town  John Powell  Peter R. Huitson 《Information processing & management》1980,16(2):91-108

The ECDIN (Environmental Chemicals Data and Information Network) project started in 1973. During the pilot phase of operation the feasibility of the system was demonstrated using a data base of 4000 compounds and the SIMAS information retrieval system. It was quickly realised that for ECDIN data management was as important as information retrieval and in November 1977, after a study of available software, the ADABAS data base management system was installed at JRC Ispra for ECDIN and other JRC data banks. A design exercise for the ECDIN ADABAS data base has been completed and parts of the existing ECDIN data base have been converted to the new system. The problems encountered and the solutions adopted are discussed. The user interface to ECDIN is still under development. When fully operational ECDIN will be available through EURONET to both casual and specialist users and, in consequence, at least two levels of user interface will be required: (a) a user friendly conversational language designed for the casual user and capable of dealing with the more common types of question, (b) a sophisticated query language capable of answering the more difficult questions, producing “one-off” reports and probably requiring both a specialist knowledge of the data base and a programmer oriented background. The first tentative steps in this direction are described.  相似文献   

Activity and Behavioral Development in Stunted and Nonstunted Children and Response to Nutritional Supplementation     

Julie M. Meeks Gardner  Sally M. Grantham-McGregor  Susan M. Chang  John H. Himes  Christine A. Powell 《Child development》1995,66(6):1785-1797

It is frequently assumed that undernutrition in young children leads to poor development through reduced activity. 3 groups of 26 1-year-old stunted children were studied: nutritional supplementation, supplementation with psychosocial stimulation, and controls. 26 nonstunted comparison children were also studied. Activity levels were measured by extensive observations in the homes, and development using 4 subscales of the Griffith's Mental Development Scales. Initially, stunted children were less active than nonstunted ones ( p < .01), but after 6 months they caught up regardless of treatment. The mental ages of the stunted children were lower than those of the nonstunted children initially, and improved with either treatment. Initially, activity levels made a significant contribution to the variance in the locomotor subscale only, but not 6 months later. Activity did not predict change in development over 6 or 12 months, nor did change in activity over 6 months predict change in development over 12 months.  相似文献

Being Subjective about Autistic Thinking and Learning to Learn     

Stuart D. Powell  Rita R. Jordan 《教育心理学》1993,13(3-4):359-370

In this paper, we discuss the deviant pattern of the development of thinking in autism and outline our thesis that the problem with autistic memory is in developing a personal episodic memory, and that this difficulty arises because of a deficit in the development of an experiencing self, which we have termed (after Brewer, 1986) an ‘ego‐self. We discuss constraints which we suggest result in learnable thinking skills remaining domain specific: difficulties with (i) language, (ii) coding, storage and retrieval of information and (iii) the role of emotions. We discuss what ‘improving the thinking’ of individuals with autism would entail and draw implications regarding fundamental requirements and caveats of teaching thinking for all individuals.  相似文献

The BASES expert statement on exercise, immunity, and infection     

Gleeson M  Walsh NP;British Association of Sport  Exercise Sciences 《Journal of sports sciences》2012,30(3):321-324

An individual's level of physical activity influences their risk of infection, most likely by affecting immune function. Regular moderate exercise reduces the risk of infection compared with a sedentary lifestyle, but very prolonged bouts of exercise and periods of intensified training are associated with an increased risk of infection. There are several lifestyle, nutritional, and training strategies that can be adopted to limit the extent of exercise-induced immunodepression and minimize the risk of infection. This expert statement provides a background summarizing the evidence together with extensive conclusions and practical guidelines.  相似文献
