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

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

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

Pedometer-determined physical activity (PA) levels in Belgian adults were provided and compared to PA scores reported in the International Physical Activity Questionnaire (IPAQ). The representative sample (N=1239) of the Belgian population took on average 9655 (4526) steps/day. According to pedometer indices 58.4% were insufficiently active. Steps/day differed significantly between gender (F = 5.0, p = .026), age groups (F = 3.3, p = .01), employment status (F = 6.2, p = .013), and days of monitoring (F = 7.4, p = .007). Steps/day were negatively correlated to the time spent sitting and positively to PA at work, in transport, and in leisure time (p < .001). Steps data can discriminate between PA levels reported in the IPAQ. Belgian population pedometer-determined PA levels are higher than those reported in samples of the United States; however, there is a wide distribution of ambulatory behavior 相似文献
