The impact of screening and advice on inattentive,hyperactive and impulsive children     

Peter Tymms  Christine Merrell 《欧洲特需教育杂志》2013,28(3):321-337

ABSTRACT

This short report is about the experiences, views and perspectives of eight parents whose children experience difficulties in learning or have disabilities. These parents have been involved in or innovated parent groups around England. Their views are presented in the light of education policy which relates to school choice and to children and young people with statements of their ‘special educational needs’. These parents’ perspectives on integration emerged as one of the main themes from the interview data  相似文献

现象与困惑：涉油犯罪规制新论     

姬文清  何松彪 《未来与发展》2009,30(11):95-97

开井放油、打孔盗油、盗窃和破坏石油生产设施的现象,在全国各个油田都有发生,“三小一点”为涉油犯罪提供了销赃路径。涉油犯罪愈演愈烈。相比之下,不断出台的政策和法律似乎显得苍白无力,如何有效规制涉油犯罪,从而保护社会、经济、环境的安全与稳定,成为时下需要深入思考的问题。本文总结了涉油犯罪的特征,剖析了犯罪的成因。并用法学、管理学、经济学、系统科学等交叉学科理论,从涉油犯罪成本、犯罪控制系统、产业链、利益分配等角度进行了规制路径的新选择。  相似文献

The economic burden of child sexual abuse in the United States     

《Child abuse & neglect》2018

The present study provides an estimate of the U.S. economic impact of child sexual abuse (CSA). Costs of CSA were measured from the societal perspective and include health care costs, productivity losses, child welfare costs, violence/crime costs, special education costs, and suicide death costs. We separately estimated quality-adjusted life year (QALY) losses. For each category, we used the best available secondary data to develop cost per case estimates. All costs were estimated in U.S. dollars and adjusted to the reference year 2015. Estimating 20 new cases of fatal and 40,387 new substantiated cases of nonfatal CSA that occurred in 2015, the lifetime economic burden of CSA is approximately $9.3 billion, the lifetime cost for victims of fatal CSA per female and male victim is on average $1,128,334 and $1,482,933, respectively, and the average lifetime cost for victims of nonfatal CSA is of $282,734 per female victim. For male victims of nonfatal CSA, there was insufficient information on productivity losses, contributing to a lower average estimated lifetime cost of $74,691 per male victim. If we included QALYs, these costs would increase by approximately $40,000 per victim. With the exception of male productivity losses, all estimates were based on robust, replicable incidence-based costing methods. The availability of accurate, up-to-date estimates should contribute to policy analysis, facilitate comparisons with other public health problems, and support future economic evaluations of CSA-specific policy and practice. In particular, we hope the availability of credible and contemporary estimates will support increased attention to primary prevention of CSA.  相似文献

经济洗衣模型     

黄龙生  刘静 《郧阳师范高等专科学校学报》1999,(6)

本文在分析用洗衣机洗衣的过程的基础上,建立了洗衣机漂洗衣物的经济模型。得到结论：如果当地水资源贫乏,相对来说水价很高,则每次漂洗可加入洗衣机正常工作需要的最少的水量．如果当地水资源丰富,水价便宜,相对来说电价很高,则每次漂洗可加入最多的上限水量。  相似文献   

CALIMERA: A new early time series classification method     

《Information processing & management》2023,60(5):103465

Early time series classification is a variant of the time series classification task, in which a label must be assigned to the incoming time series as quickly as possible without necessarily screening through the whole sequence. It needs to be realized on the algorithmic level by fusing a decision-making method that detects the right moment to stop and a classifier that assigns a class label. The contribution addressed in this paper is twofold. Firstly, we present a new method for finding the best moment to perform an action (terminate/continue). Secondly, we propose a new learning scheme using classifier calibration to estimate classification accuracy. The new approach, called CALIMERA, is formalized as a cost minimization problem. Using two benchmark methodologies for early time series classification, we have shown that the proposed model achieves better results than the current state-of-the-art. Two most serious competitors of CALIMERA are ECONOMY and TEASER. The empirical comparison showed that the new method achieved a higher accuracy than TEASER for 35 out of 45 datasets and it outperformed ECONOMY in 20 out of 34 datasets.  相似文献

远程教育微观经济学的基本概念—远程教育经济学研究的研究（三）     

丁兴富 《现代远程教育研究》2001,(3):7-13

远程教育微观经济学研究远程教育事业或产业的经济现象和经济活动规律。主要包括对远程教育系统和远程教育过程的经济学研究两部分。教育系统的经济学研究主要关注远程教育系统、院校、项目的投资效率和成本分析；而远程教育过程的经济学研究则主要关注远程教育课程开发与发送、多种媒体教学以有各类学习支助服务中的投入产出、成本核算 和成本分析。同时将它们传统面授教育投资进行比较，从而为远程教育系统的设计、规划和管理，以及为基于信息技术和媒体的远程教育课程开发和远程教与学的设计提供可靠的经济学依据。  相似文献
