关于生命表编制方法的新认识     

赵萍  杨泽祥 《科技通报》2014,(9)

人口生命表作为人口统计学的一项重要分析技术,简明而直观的反映了人口数目因死亡而变动的过程,而死亡概率是生命表中一个最重要的元素,它的精确程度将直接影响着生命表质量的高低。大部分的文献都认为指数死亡概率比伐尔死亡概率精确,本文的观点恰好相反,我们认为,伐尔死亡概率比指数死亡概率要精确。  相似文献   

Plastic people in pinstripe suits: an exploration of the views of Irish parents on the publication of school league tables     

O. McCormack  R. Lynch  J. Hennessy 《Educational studies》2015,41(5):513-533

While the publication of school league tables is prohibited by law in Ireland, the publication of data categorising university placements achieved per school has become common practice. A central argument advanced in this endeavour includes the provision of information for parents. The views of parents on this issue have, until now, not been explored in Ireland. The current paper outlines the findings of a national survey of 1915 parents on the publication of school league tables. The findings of this research highlight a widespread rejection of the practice. Concerns surrounding the narrowing of educational experience, the intensification of performance pressures and the rise of elitism in schools were noted. Calls for greater teacher accountability were also noted and deemed to transcend the publication of school league tables.  相似文献

League tables in educational evidence-based policy-making: can we stop the horse race,please?     

Eva Klemenčič 《比较教育学》2018,54(3):309-324

International large-scale student assessments (ILSAs) in education represent a valuable source of information for policy-makers, not only on student achievements, but also on their relationship with different contextual factors. The results are partly described in the official studies’ reports; more can be derived from the publicly released data sets. However, league tables are often the only evidence used in policy debates and decisions on education. Indeed, the comparison of student achievement across the participating educational systems is a legitimate proxy for estimating countries’ development and productivity, but the use of league tables more often turns into ‘horse-ranking’, ignoring the contexts of teaching and learning. This is often supported by the media, turning the use of results into their abuse. The purpose of this paper is to discuss the use and misuse of league tables in reporting ILSA results, vs. the use of data for in-depth analysis in order to make informed decisions.  相似文献
