There was extensive mutual influence between BBC Local Radio and Independent Local Radio (ILR), particularly during the set-up periods for both systems. Although they competed for locations and frequencies, often fiercely, they developed through a single governmental mechanism and came to feel at times a close affinity. Had the proposals of the Annan Committee been agreed, that these 2 systems of local radio should be brought together under a single regulator, both could have benefited and the long-term prospects for local radio in the UK might have been enhanced.  相似文献

Tony Lingard, Head of Learning Support, Camborne School and Community College, Cornwall, questions whether the National Literacy Strategy is raising the achievement of lower attainers and suggests adaptations, based on his own Literacy Acceleration programme, which he argues could make the Strategy far more effective.  相似文献

The aim of the present study is to conduct a systematic review research which focuses on research studies into the school practicum. In order to identify the main issues and also to provide a contemporary picture of practicum, 114 studies published on the topic are reviewed and analysed in terms of: (i) aims, (ii) main participants, (iii) methodology used and (iv) the main outcomes emerging. Many of the reviewed studies take pre-service teachers as their main participants. The review also shows that many practicum studies are relatively small-scale studies since they are mainly qualitative focused and findings derived from a relatively small sample. This suggests that more large-scale studies are needed in the field in order to provide greater insight into teaching practicum. Finally, this systematic review provides some food for thought in the area of practicum research and promotes further studies in this complex field.  相似文献

Current trends in swimming biomechanics are focused on accurate measurements. Nowadays, reliable calibration methods have been proposed to reach an accuracy of about 1 mm on rigid structure. But the question remains about the final accuracy for three-dimensional hand kinematics measurement during the underwater phase of front crawl swimming. Furthermore, most research is based on manual tracking with two or more cameras. In this paper we propose a protocol to acquire three-dimensional hand kinematics when swimming in a specific pool with a motion analysis system behind windows. Results highlight the benefits of using such a system in terms of accuracy and feasibility: the time allowed for post-processing is ten times lower and the quantified improved accuracy is better than with manual tracking.  相似文献

The literature on cultural capital has had relatively little to say about television viewing, except insofar as television has served as a negative point of reference in relation to which other cultural practices register their distinctiveness. This article, by contrast, examines the respects in which practices of distinction are operative within the space of broadcast television. Looking first at the ‘internal economy’ of television as expressed in the relations between genre, programme and channel preferences, it then examines how these preferences are related to occupational class, gender, level of education and ethnicity. While showing that divisions within the space of broadcasting are most powerfully articulated in terms of age and gender, the article also shows that occupational class and level of education play important roles in stratifying television audiences along traditional ‘high’/‘low’ lines. A closer analysis of the relations between these variables reveals more complex patterns of distinction, particularly in the place occupied by ‘new drama’ and ‘new comedy’ in the preferences of younger, well-educated viewers.  相似文献

The early childhood educational field has garnered attention with initiatives to foster skill acquisition in young children prior to kindergarten entry. These initiatives, in conjunction with the rigorous demands of curricular reform and a burgeoning accountability movement, invoke questions regarding the adequacy of the instruments used to assess young children and the inherent difficulties in conducting such assessments. Because the effectiveness of education relies critically on the sound diagnoses of children's readiness for learning and the measurement of their subsequent progression throughout the schooling process, critical issues in early assessment must be addressed. An examination of past practices was synthesized with recent research to focus awareness on the insufficient content domain, restrictive context, adverse timing and questionable psychometric properties, specifically the inappropriate norms and low predictive validity, of many instruments. Both the implications of and compensatory strategies for each issue are considered. © 2004 Wiley Periodicals, Inc. Psychol Schs 41: 737–749, 2004.  相似文献

IntroductionIt is unclear what is the best strategy for applying patient-based real-time quality control (PBRTQC) algorithm in the presence of multiple instruments. This simulation study compared the error detection capability of applying PBRTQC algorithms for instruments individually and in combination using serum sodium as an example.Materials and methodsFour sets of random serum sodium measurements were generated with differing means and standard deviations to represent four simulated instruments. Moving median with winsorization was selected as the PBRTQC algorithm. The PBRTQC parameters (block size and control limits) were optimized and applied to the four simulated laboratory data sets individually and in combination.ResultsWhen the PBRTQC algorithm were individually optimized and applied to the data of the individual simulated instruments, it was able to detect bias several folds faster than when they were combined. Similarly, the individually applied algorithms had perfect error detection rates across different magnitudes of bias, whereas the error detection rates of the algorithm applied on the combined data missed smaller biases. The performance of the individually applied PBRTQC algorithm performed more consistently among the simulated instruments compared to when the data were combined.DiscussionWhile combining data from different instruments can increase the data stream and hence, increase the speed of error detection, it may widen the control limits and compromising the probability of error detection. The presence of multiple instruments in the data stream may dilute the effect of the error when it only affects a selected instrument.  相似文献
