5-6岁幼儿故事复述能力研究——以西安市4所幼儿园为例

幼儿故事在幼儿发展和幼儿园教学中起着非常重要的作用,不同的幼儿在不同的故事呈现方式中表现出不同的复述特点。本文采用多彩光谱语言评估标准,对从西安市市区4所不同类型幼儿园中获得的126份语言样本进行了分析。研究结果显示,图书组和录音组幼儿的故事复述能力差异不显著,视频组幼儿在故事复述能力测试中总体得分较低。尽管从总体上看,许多幼儿的复述能力处于同一水平,但构成复述能力的要素却存在较大的个体差异。不同幼儿在同一语言活动中复述故事的字数和语言特点各不相同。     

基于考生水平表现标准评价的探索与实践——以2014年高考语文(天津卷)为例

论述了近年来天津市基于考生水平表现标准的高考评价的理论探索与实践。以2014年高考(天津卷)为例展现基于考生水平表现标准评价的具体应用和分析结果。笔者依据《考生水平表现标准》,从知识范畴和能力属别两个维度,对全市、不同区域全体及不同水平组的普通高中应届生考生在2014年高考语文试卷的作答表现进行分析。全市共有90.23%的考生达到基本水平及以上,且分别在语言知识和语言表达知识范畴及分析综合能力属别的作答表现最好。2014年不同区域考生的语文水平差距在缩小,趋于均衡。通过典型试题进一步分析了考生水平和教学质量中存在的共性问题,并提出了切实改变课堂教学方式,加强积累、注重落实,提高学生的思维品质等教学建议。     

以评估促进任职院校信息化教育发展

基于可拓学的高校教师教学质量评价

完善高校教师质量评价方法对提高教师的教学水平和教学积极性具有重要意义。传统的评价方法以定性和简单算术运算分析为主,带有较强的主观片面性。可拓学是用形式化模型研究事物拓展的可能性和开拓创新的规律与方法,并用于解决矛盾问题的科学。教学质量评价指标的多样性和由单指标给出的评价结果的不相容性,符合可拓学解决矛盾问题的基本原则。利用可拓学理论和方法建立的高校教师教学质量评价物元模型,能在事先没有人为设计指标权重的基础上,通过关联函数和关联度,反应评价单元的归属程度以及评价等级值,较好地解决指标权重与主观片面性问题,为高校教师教学质量评价提供一种新的思路。

Correlation analysis of performance measures for multi-label classification

In many important application domains, such as text categorization, scene classification, biomolecular analysis and medical diagnosis, examples are naturally associated with more than one class label, giving rise to multi-label classification problems. This fact has led, in recent years, to a substantial amount of research in multi-label classification. In order to evaluate and compare multi-label classifiers, researchers have adapted evaluation measures from the single-label paradigm, like Precision and Recall; and also have developed many different measures specifically for the multi-label paradigm, like Hamming Loss and Subset Accuracy. However, these evaluation measures have been used arbitrarily in multi-label classification experiments, without an objective analysis of correlation or bias. This can lead to misleading conclusions, as the experimental results may appear to favor a specific behavior depending on the subset of measures chosen. Also, as different papers in the area currently employ distinct subsets of measures, it is difficult to compare results across papers. In this work, we provide a thorough analysis of multi-label evaluation measures, and we give concrete suggestions for researchers to make an informed decision when choosing evaluation measures for multi-label classification.     

基于AHP-FCE的科技园区可持续发展能力评价研究*——以广东省科技园区为例

从可持续发展的角度阐述科技园区可持续发展能力的内涵,构建科技园区可持续发展能力的评价指标体系,运用层次分析-模糊综合评价法建立科技园区可持续发展能力的评价模型,对广东省15个城市科技园区可持续发展能力进行了定性和定量评价,结论为：粤东西科技园区可持续发展能力总体上远远落后于“珠三角”城市,粤东三城市科技园区的可持续发展能力略高于粤西的三个城市;并提出产业转移和劳动力转移、创新驱动、产业集聚和营造良好的环境等建议来实现广东省科技园区协调和可持续发展。     

生态文明导向下区域绿色发展研究——以浙江省为例

在回顾国内外绿色发展研究现状的基础上,阐述中国绿色发展的概况,以浙江省为研究对象,构建灰熵评价模型,评估2011—2015年浙江省的绿色发展水平。结果表明,浙江省近5年绿色发展水平逐年提高,2013年之前,环境是推动绿色发展的主要因素,2013年之后经济发展是推动绿色发展的主要因素。指出区域绿色发展不仅需要坚持生态文明为导向,完善法律法规,增加投入推动科技创新,加强宣传教育,还要发挥地方特色和地方优势。     

Managing misspelled queries in IR applications

Our work concerns the design of robust information retrieval environments that can successfully handle queries containing misspelled words. Our aim is to perform a comparative analysis of the efficacy of two possible strategies that can be adopted.     

How medical practice evolves: Learning to treat failing hearts with an implantable device

In this article we propose that medical practice evolves as a result of progress along three different pathways: improvement in the ability to develop effective medical technologies, learning in medical practice, and advances in biomedical scientific understanding of disease. The relative importance of these three pathways varies from case to case, and often they interact strongly. More specifically, we argue here that in cases of therapeutic innovation where a new medical technology is involved the advance in medical practice is driven largely by the ability to develop and use effective medical artifacts and the interactive sequence among these interdependent pathways often starts with what is learned in practice and not in science. While we state this argument in general, we develop it in detail in a longitudinal and contextual case study of the emergence and evolution of a treatment for advanced heart failure based on an implantable device, the Left Ventricular Assist Device (LVAD). Our findings show that an essential aspect of the evolution of the LVAD therapy is collective and cumulative learning that requires experience that only can be gained through the actual use of LVADs. We discuss the theoretical and policy implications that follow from our understanding of how medical practice evolves for research on the evolution of medical practices and new medical technologies, and policies about the evaluation of rapidly moving medical practices and clinical research involved in their advancement.
