图书馆情报学主要研究方法:了解、选择及使用     

储荷婷 《图书情报工作》2019,63(1):146-152

[目的/意义]研究方法在学术研究中发挥着至关重要的作用。确认图书馆情报学领域主要的研究方法，并对它们进行了解熟悉，以在开展研究时能合理选择、灵活使用，确保研究质量。[方法/过程]对近2 000篇图书馆情报学领域的研究文献以及相关研究方法论文进行内容分析，在此基础上对研究方法的类分命名、图书馆情报学界主要的研究方法的确定、特点和使用注意事项进行介绍和讨论。[结果/结论]研究方法应以数据收集法而不是数据分析法命名。图书馆情报学领域常用的研究方法包括实验法、问卷法、理论研讨法、内容分析法、访谈法和书目计量法，每种方法都有各自的特点。因而在选择使用时，既应根据具体研究课题及研究方法之特性，也要考虑使用注意事项，并尽量在同一研究中采用两种或更多的方法，以扬长避短，更有效地展开研究。  相似文献

Exploring mechanisms of rapid automatized naming to arithmetic skills in Chinese primary schoolers     

Yiji Wang  Xiaolin Ye  Ciping Deng 《Psychology in the schools》2020,57(4):556-571

Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation. Using a sample of Chinese primary school students (N = 170), results showed that while RAN was associated with all key aspects of arithmetic skills, the relations of RAN–arithmetic procedure and RAN–word problems may be dependent on that of RAN–arithmetic fluency. Supporting the processing speed hypothesis, results further suggested that processing speed may underlie the relation between RAN and arithmetic performance. Findings made unique contribution to understanding the effect of RAN on arithmetic performance and cognitive mechanisms that may underpin this association in the context of Chinese culture.  相似文献

Observations on the temporal correlates of reading failure     

Raymond M. Klein 《Reading and writing》2002,15(1-2):207-231

The definitions of developmental dyslexia andtemporal processing are discussed and severalconstruals of what a temporal processingdeficit might entail are illustrated. Then,using a framework developed by Farmer & Klein(1995), the proposal that a temporal processingdeficit (in vision, audition, or both) might bethe root cause of some proportion of cases ofdevelopmental dyslexia is introduced andvarious research strategies for testing thisproposal are identified. The symposium paperswhich address this general question using arange of these strategies are then criticallyreviewed. It is noted that whereas reading isa recent artifact not yet subject to any directselection pressure, its normal performancerequires the use of, and connections between,the highly evolved modules for visual patternrecognition and language. Within vision andlanguage redundant coding, which permitsperformance in the face of injuries anddegraded input, also makes it difficult todetect subtle deficits (whether temporal, ornot) unless precise tests are used. Yet suchdeficits may degrade performance on tasks (suchas reading) which require the non-copiousconnections between vision and language. Theefficacy of this pathway, I suggest, ismeasured by performance on the rapidautomatized naming (RAN) test.  相似文献

论鲁迅杂文中类型人物的命名艺术     

杨文惠  顾颖 《咸阳师范学院学报》2002,17(1):27-29

鲁迅十分重视为杂中的类型形象命名，他为人物命名的手法堪称为一种艺术，在鲁迅的杂中，人物名称不只是简单的代号，它和人物的内在本质有着密切的联系，我们往往可以通过名称去认识人物。  相似文献   

Space- and time-efficient approach for virtual machine provisioning     

胡博林  雷州  许东  李建敦 《上海大学学报(英文版)》2011,15(5):451-455

As a new promising paradigm, cloud computing can make good use of economics of scale and elastically deliver almost any IT related services on demand. Nevertheless, one of the key problems remaining in cloud computing is related to virtual machine images, which require a great amount of space/time to reposit/provision, especially with diverse requests from thousands of users simultaneously. In this paper, by using the splitting and eliminating redundant data techniques, a space and time efficient approach for virtual machines is proposed. The experiments demonstrate that, compared with existing solutions, our approach can conserve more disk space and speed up the provisioning of virtual machines.  相似文献
