[目的/意义]现阶段很多图书馆都出现了空间不足、环境老化的现象,空间再造成为图书馆的一个迫在眉睫、亟待解决的重大课题。[方法/过程]根据图书馆空间五要素要求原则,从读者属性角度分析图书馆空间短缺的原因是来自读者对图书馆空间的需求差异,把握读者属性的特点才能更好的进行空间再造。[结果/结论]针对不同类型的图书馆给出有效改善图书馆空间紧缩或阅读空间空置率高等现状的相应思路。 相似文献

[目的/意义] 针对学术期刊文本资源语义标注仍存在的通用本体难以构建、标注粒度单一两大问题,提出基于SKOS的学术期刊多粒度语义标注方法,从而进一步推进语义标注的应用发展,更好满足用户的多粒度学术信息需求。[方法/过程] 在对《中国汉语主题词表》进行SKOS描述的基础上,以学术期刊文本资源为对象,实现其多粒度语义标注,并通过实证研究验证该方法的可行性。[结果/结论] 利用SKOS实现对学术期刊文本资源进行多粒度语义标注,较之当前学术检索系统中的标注结果,在"查全"查准"内部特征检索入口"检索结果反馈形式"4个方面具有一定优势。 相似文献

This study extends instructional communication research on extra-class communication (ECC) by presenting an integrative analysis comparing the explanatory utility of student- and instructor-oriented reasons for student engagement in frequent ECC. Results from 495 college students suggested that student-oriented reasons, specifically the relational and functional student motives, were the only significant, positive predictors of students’ perceptions of frequent ECC engagement. Other student motives (excuse making, participation, sycophancy) and perceptions of instructor approachability did not significantly predict perceived frequency of ECC engagement. 相似文献

Explicating the third-person perception (TPP) as a cognitive fallacy in the process of comparative social judgment of media effects, we propose that not all self–other perceptual gaps in media effects should be considered as TPP. When there is reasonably valid and accurate information regarding self vis-à-vis others on media consumption and vulnerability to media influence, the associated self–other gaps in media effects are not exaggerations, hence, not TPP. TPP results from cognitive biases in information retrieval and application in the process of comparative social judgments. Such biases are in the forms of self-other information differential, assimilation, contrast, and anchoring effects. Caveats in interpretation of extant evidence and implications for future TPP research are discussed. 相似文献

英国高等教育经过800余年的不断改革与发展,已经在自主、自治的独立体系下形成了自主运行机制。英国高等教育发展的经验告诉我们:如果不允许各大学采取发展它们自己的基本政策,不允许它们有决定如何履行它们对社会的责任的余地,那么结果就是愚钝和平庸。这种观点对我们高等教育改革不无启迪作用。 相似文献

ABSTRACTA socio-technical approach is taken to explore a digital archive of Australian Indigenous cultural heritage. The Living Archive of Aboriginal Languages is considered in terms of what it is currently doing and what it was intended to do. Two ethnographic stories focusing on user interactions and the outcomes of an online survey serve to evaluate the effectiveness of the Archive from the perspective of different users. This is then juxtaposed with a consideration of the original grant application, outlining what was envisaged for the project. This analysis serves to highlight some of the contingent relations and diverse socio-technical aspects of a specific knowledge infrastructure, as it allows multiple forms of interaction, new connections and generative activities as people discover, access and interact with the content now and into the future. 相似文献

There is no denying the impact that the coronravirus disease (COVID-19) outbreak has had on many aspects of our lives. This article looks at the potential impact of COVID-19 on student learning as schools abruptly morphed into virtual learning environments using data from several instructional, practice, and assessment solutions offered by Renaissance. First, three hypothetical learning scenarios are considered using normative data from Star assessments to explore the potential impact on reading and math test performace. Next, data on Focus Skills are used to highlight which grades may have missed the most foundational math and reading content if instruction was stopped or reduced. Last, data from two of Renaissance's practice tools are used to evaluate whether students were practicing key skills following school closures. The article concludes that academic decline will likely occur but may be tempered by the increased use of practice tools; effects may look different for math and reading; and may impact grades and schools differently. As such, schools may need to leverage decision-making frameworks, such as the Multi-tiered Systems of Support/Response-to-Intervention (MTSS/RTI) framework, more than ever to identify needs and target instruction where it matters most when school begins in fall 2020. 相似文献
