Most educational research examines school outcomes at certain stages or at the final stage of the school career. This article looks at the entire school career and the transition to the labour market. It focuses on key transitions to identify the educational institutional arrangements that either help or hinder school and labour market success among the most disadvantaged groups in the Netherlands: young people of Moroccan and Turkish descent. The Dutch educational system is one of the most complicated school systems in Europe. Consequently, parents and children have to make many ‘choices’ when navigating it. Many of these key ‘choice’ moments are selection points, either because they are not real choices but dependent upon a teacher’s recommendation or because parents and pupils need a great deal of information about the school system in order to make a choice. This usually results in inequalities for the most disadvantaged groups. Because selection is disguised as ‘choices’, the structural inequalities of the Dutch school system are not usually perceived as blocking mechanisms for disadvantaged students  相似文献

The paper attempts to identify the extent to which modes of knowledge can be associated with different patterns of and assumptions about power.It discusses the meanings and scope of power itself, i.e. both within and beyond epistemic communities, as against ‘social robustness’ implying more democratic or inclusive forms of evaluation.It analyses the extent to which knowledge has shifted from an internalist perspective relying on the prestige of epistemic communities towards socially relevant assumptions resting within social contexts. It discusses the factors affecting types of power patterns, such as: the nature of sponsors’ objectives and the uses to which they might put knowledge; epistemic characteristics; the nature of the resource required, and the stage of finalisation reached. It sketches the range of models of sponsorship to which knowledge is subjected – from that of the free standing and autonomous individual through different patterns of sponsorship to the directly managed.It attempts to link these classifications to a range of empirical examples, including the power of knowledge in government and in crossing the boundaries between universities and industry.In discussing the reciprocal relationships between power and knowledge, it accepts that power affects the identification, use and transmission of knowledge. It is concerned, however, to question overdetermined perspectives of the relationships between knowledge and power whose mutual impacts may be strong but not easily predicted or defined.  相似文献

ABSTRACT

Studies in several sports have shown the benefits of adapting the playing environment to fit junior players. Frequently the changes are pragmatic choices based on space constraints or existing line markings, or the result of simple scaling based on stature. In this study, a method of scaling the cricket pitch length is presented which is based on the age-specific size and performance of the bowlers and batters. The objective was a pitch length which enabled young bowlers to bowl good length deliveries while releasing the ball at a more downward angle, similar to elite bowlers. The steeper release angle has the benefit of reducing the sensitivity of the ball flight distance to the variability of ball release. Based on data from county standard under-10 and under-11 players a pitch length of 16.22 yards (14.83 m) was calculated, 19% shorter than previously recommended for under-11s in England. A shorter pitch also increases the temporal challenge for batters, encouraging a wider variety of shots and improved anticipation skills. Pitch lengths scaled in this way to fit the players’ abilities as they develop will enable a more consistent ball release by bowlers and more consistent temporal demand for batters.  相似文献

The study compared differences and similarities between WISC and WISC-R scores for 48 ten- and thirteen-year-old EMR students, who were matched according to sex and race. The WISC-R yielded significantly lower VS, PS, and FS IQ scores than the WISC for this predominantly rural Georgia population. The FS IQ scores from the WISC-R averaged 7.5 points lower than the WISC FS IQs, with similar differences noted for VS and PS scores. There was no significant difference in FS IQs between the two age groups. Results suggest that many children classified as “Borderline” or slightly above by the WISC will be classified as “Mentally Deficient” by the WISC-R.  相似文献

Important problems exist in the field of communications theory whose solution is in the form of an expectation of a function of a random variable. Often it is not computationally feasible to evaluate these moments exactly. This paper presents a geometric bounding technique that yields tight upper and lower bounds to generalized moments of a broad class of random variables. This technique produces excellent results for these communications theory problems.  相似文献
