Aspects of ‘relevance’ in the alignment of curriculum with educational standards

With over 60,000 US K-12 science and mathematics education standards and a rapid proliferation of Web-enabled curriculum, retrieving curriculum that aligns with the standards to which teachers must teach is a key objective for educational digital libraries. However, previous studies of such alignment use single-dimensional and binary measures of the alignment concept. As a consequence, they suffer from low inter-rater reliability (IRR), with experts agreeing about alignments only some 20–40% of the time. We present the results of an experiment in which the alignment variable was operationalized using the Saracevic model of relevance ‘clues’ taken from the everyday practice of K-12 teaching. Results show high IRR across all clues with IRR on several specific alignment dimensions significantly higher than on overall alignment. In addition, a model of overall alignment is derived and estimated. The structure and explanatory power of the model as well as the relationships between alignment clues differ significantly between alignments of curriculum found by users themselves and curriculum found by others. These results illustrate the usefulness of clue-based relevance measures for information retrieval and have important consequences for both the formulation of automated retrieval mechanisms and the construction of a gold standard or benchmark set of standard-curriculum alignments.

强制性且带有激励措施的OA政策调研及实例分析

[目的/意义] 随着国际组织、国家和科研及基金资助机构对开放获取（OA）运动的支持力度进一步加强,开放获取政策不仅在数量上不断增加,其强制力度也在加深,促进了全球科研交流的发展。总结梳理强制性且带有激励措施的OA政策的实践进展,可为我国相关政策主体制定与改进相应的OA政策提供借鉴和参考。[方法/过程] 首先通过文献调研及网站调研强制性且带有激励措施的OA政策的制定现状,分别概括基金资助机构与科研机构的此类政策所包含的激励措施的特点;其次,以科研机构为例,利用机构WOS论文在机构指定的存储库中的存储情况来反映机构OA政策的执行效果,对比分析此类政策与未制定激励措施的强制性OA政策、鼓励性OA政策实施效果的差异。[结果/结论] 目前制定强制性且带有激励措施的OA政策的机构较少,基金资助机构主要采取削减项目资助资金或取消受资助者再次申请基金资格的惩罚性措施来督促科研人员遵守其OA政策,科研机构则将科研人员遵守OA政策的情况与其绩效评估相挂钩,借以激励机构成员实现研究产出的开放获取;实证分析发现强制性且带有激励措施的OA政策相比于另外两类OA政策执行力度更强、实施效果更好。     

我国科研人员对科技信息开放获取的态度————以中国科学院科研人员为例

文章以对中国科学院部分科研人员的访谈和问卷调查为基础,调查我国科研人员对科技信息开放获取的态度及意愿,并从开放获取资源、科研机构和科研人员自身特点等角度分析了科研人员参与科技信息开放获取的影响因素,建议政府、科研机构和科研资助机构要积极扶持开放获取期刊的发展,将开放获取期刊纳入科研评价体系之中,支持学术论文的自存储。     

预贮处理对金柚耐藏力的影响

试验结果表明,与预贮4天和20天的处理相比较,预贮10—15天的金柚果实在贮藏期间失重较少,呼吸速率较低,可溶性固形物和总糖含量较高,枯水和腐烂率较低,果实较耐贮藏。

《金瓶梅词话》作者为武进作家白悦续考

在笔者系列论文的第一篇《（金瓶梅词话）作者为武进作家白悦》之后,从皇甫济为白悦诗文集《白洛原遗稿》所作的序、徐阶为白悦撰墓志铭及《金瓶梅词话》内证等入手,可以进一步证实《金瓶梅词话》的作者为江苏武进作家白悦,并由此对这部小说的最早传播作出合理的推测。     

情欲挤压下的心理畸变——用弗洛伊德性论解读曹七巧形象

运用弗洛伊德的性论解读《金锁记》中曹七巧的形象,可以得出如下结论：曹七巧心理的畸变,从某种程度上说,是其情欲受到压抑变相释放的结果。在情欲的挤压下,曹七巧历经了三次心理畸变,使其人性扭曲,人生错位。     

Kalgoorlie as the Global Centre for Gold Metallurgical Innovation 1902-1907

Faced with the problem of how to process valuable refractory sulphide ore in the early 1900s, Kalgoorlie mining engineers and metallurgist, and their consultants, borrowed ideas from a variety of international sources to develop new equipment and new procedures. This paper examines the sources of these innovations and how they spread with remarkable speed through the medium of the tight-knit group of international metallurgical consultants. The inter-relationship between international technological transfer and increased local inventiveness, stimulated by the rapid changes in technology, and the opportunities and limitations experienced by Australian metallurgical inventers in the 1900s are also examined.
