Quality of grey literature in the open access era: Privilege and responsibility     

Paola?De?CastroEmail author  Sandra?Salinetti 《Publishing Research Quarterly》2004,20(1):4-12

Conclusions We are living a deep change in the information transfer process involving the different actors of the editorial scene (from authors to editors, web-editors, e-publishers and readers), who occasionally play different roles at the same time (e.g., authors sometimes bypass the editor thus assuming direct responsibilities in the diffusion of documents in the Internet). Furthermore, information producers, managers or seekers often show twofold personalities like Dr. Jekyll and Mr. Hyde. They would like to find all documents free on the Internet and be able to read original, reliable, and high quality information, but they are sometimes reluctant to spread their papers through online nonofficial channels as they care for the impact factor, prestige, and career advancement. It is a revolutionary period in which new and alternative forms of scholarly communication live together with more traditional ones and the future is difficult to define. Recent initiatives of open access—such as Pubmed Central, Public Library of Science, Budapest Open Access Initiative—are contributing to define new trends in the editorial market, challenging the traditional distribution channels, mainly managed by commercial editors, and placing the authors’ role and publication copyrights under severe discussion. In this landscape, GL now has new dignity and becomes closer and closer to innovative scientific publications supported by researchers in view of a generalised movement towards open access. The nuances of grey are becoming lighter and lighter. The questions are many, the answers few, but, in any case, the ethical responsibility of producing and issuing quality documents can never be disregarded.  相似文献   

PubMed, Internet Grateful Med, and Ovid: a comparison of three MEDLINE Internet interfaces     

De Groote SL 《Medical reference services quarterly》2000,19(4):1-13

Three MEDLINE Internet interfaces are compared: PubMed, Internet Grateful Med, and Ovid MEDLINE. Although these interfaces all search MEDLINE, significant differences exist in terms of their search interfaces, presentation of results, and special features. This paper examines these variations and explores some of the advantages and disadvantages of the three interfaces.  相似文献   

Secondary-school students' motivation for portfolio reflection     

H.L. De Bruin  A.E. Oosterbaan  F.J. Prins 《Irish Educational Studies》2013,32(4):415-431

Several studies concluded that deep reflection is infrequently reached in student portfolios. An explanation for these disappointing conclusions might be that motivation for portfolio reflection determines the quality of reflection. This study aimed to examine the relationship between motivation for using digital portfolios and reflection. Participants were 156 eleventh-grade students in secondary education, whose motivation for composing a digital portfolio was measured by the motivation part of the Motivated Strategies for Learning Questionnaire. Portfolios of 37 of the 156 students were examined in terms of the amount and nature of reflection by means of a coding scheme based on Mezirow's model of transformative learning. On average, one-fifth (19.5%) of the paragraphs in a portfolio contained reflection, and paragraphs with deep reflection were hardly found (0.8%). It was concluded that motivation for composing a portfolio was fair, but not related to the amount and nature of reflection. This exploratory study gives rise to further research into factors that might influence the quality of portfolio reflection.  相似文献

大学生体育消费行为决定因素的定量分析——以湖北为例   总被引：11，自引：0，他引：11  

段鹏  肖德  赵汉华 《体育科学》2007,27(5):36-40

对学生的体育消费行为进行分类，通过问卷调查的形式，采用统计、计量分析方法，深入分析每类体育消费行为的决定因素及与决定因素之间的定量关系。结果显示，除体育运动的兴趣爱好等主观因素外，学生年生活费用水平、课程压力大小、性别是影响学生体育实物消费的主要客观因素；学生年生活费用水平、性别是影响学生体育信息消费的主要客观因素；学生来源是影响学生体育劳务消费的主要客观因素。这对更深刻地认识体育消费行为、预测高校学生体育消费支出有重要意义。  相似文献   

The Poverty of Constructivism     

Derek Louis  Meyer 《Educational Philosophy and Theory》2009,41(3):332-341

Constructivism claims to be a postepistemology that replaces 'traditional' concepts of knowledge. Supporters of constructivism have argued that progress requires that pre-service teachers be weaned off traditional approaches and that they should adopt constructivist views of knowledge. Constructivism appears to be gaining ground rapidly and should no longer be viewed as an exercise in radical thinking primarily aimed at generating innovative teaching. It has become an integral part of the pedagogic mainstream. Close examination of the theoretical foundations of constructivism, however, reveals that the basic assumptions of constructivism are flawed. Far from being a postepistemology, constructivism simply regresses to a pre-Renaissance mindset with theology replaced with a psychologism. Constructivists should be aware that the implications of constructivism for future generations may be both profound and non-benign.  相似文献
