Clinical and diagnostic approaches to special educational needs do not translate easily into educational models. In some cases, these approaches can serve to limit understanding of children's wider needs. Children with specific speech and language difficulties (SSLD) are a case in point. Clear criteria exist for identification, but identification mechanisms may not relate to the child's wider educational needs. This paper addresses the ways that children with SSLD present in mainstream educational settings. The study aimed to identify all Year 3 children with SSLD in two English local education authorities. One hundred and thirty-three children (95 boys and 37 girls were identified). Sixty-five per cent of the children were in mainstream schools, 14.3 per cent in mainstream schools with designated units and the remainder in special schools. Half were at stage 5 of the Code of Practice, with most of the remaining participants at stage 3. Children experienced a wide range of difficulties, in addition to their primary speech and language problems. Patterns of difficulties varied across children, and associations existed between particular forms of language problems and learning and relationship problems. Professionals (teachers, educational psychologists and speech and language therapists) varied in their understanding of the children's needs. The data highlight the range and diversity of the needs of children with specific speech and language difficulties and the need for a multi-professional approach to these children. It is argued that ‘best practice’ for these children must consider the impact of speech and language problems on children's access to the curriculum and their social and behavioural needs. Narrow diagnostic models do not provide the appropriate information to inform educational practice and support inclusive policies.  相似文献

Design, implementation, and re-engineering of operating systems are still an ambitious undertaking. Despite, or even because, of the long history of theory and practice in this field, adapting existing systems to environments of different conditions and requirements as originally specified or assumed, in terms of functional and/or non-functional respects, is anything but simple. Especially this is true for the embedded systems domain which, on the one hand, calls for highly specialized and application-aware system abstractions and, on the other hand, cares a great deal for easily reusable implementations of these abstractions. The latter aspect becomes more and more important as embedded systems technology is faced with an innovation cycle decreasing in length. Software for embedded systems needs to be designed for variability, and this is in particular true for the operating systems of this domain. The paper discusses dimensions of variability that need to be considered in the development of embedded operating systems and presents approaches that aid construction and maintenance of evolutionary operating systems.

Publishing research, to be effective and useful, requires the participation of scholars and practitioners in many disciplines: literature, history, sociology, psychology, technology, economics, and education. Examples are drawn from trade and scholarly publishing. The results of such research can benefit all segments of the industry. Beth Luey is director, Scholarly Publishing Program at Arizona State University and have been editor of Publishing Research Quarterly since 1988. She is the author of several books, includingHandbook for Academic Authors.  相似文献

OBJECTIVES: Medicine must keep current with the research literature, and keeping current requires continuously updating the clinical knowledge base (i.e., references that provide answers to clinical questions). The authors estimated the volume of medical literature potentially relevant to primary care published in a month and the time required for physicians trained in medical epidemiology to evaluate it for updating a clinical knowledge base. METHODS: We included journals listed in five primary care journal review services (ACP Journal Club, DynaMed, Evidence-Based Practice, Journal Watch, and QuickScan Reviews). Finding little overlap, we added the 2001 "Brandon/Hill Selected List of Print Books and Journals for the Small Medical Library." We counted articles (including letters, editorials, and other commentaries) published in March 2002, using bibliographic software where possible and hand counting when necessary. For journals not published in March 2002, we reviewed the nearest issue. Five primary care physicians independently evaluated fifty randomly selected articles and timed the process. RESULTS: The combined list contained 341 currently active journals with 8,265 articles. Adjusting for publication frequency, we estimate 7,287 articles are published monthly in this set of journals. Physicians trained in epidemiology would take an estimated 627.5 hours per month to evaluate these articles. CONCLUSIONS: To provide practicing clinicians with the best current evidence, more comprehensive and systematic literature surveillance efforts are needed.  相似文献
