This article summarizes the effects of the increasing global trend towards measuring research quality and effectiveness through, in particular, publication‐based metrics, and its effects on scholarly communication. Such metrics are increasingly influencing the behaviour patterns of administrators, publishers, librarians, and researchers. Impact and citation measures, which often rely solely on Thomson Scientific data, are examined in the context of university league tables and research assessment exercises. The need to establish alternate metrics, particularly for the social sciences and humanities, is emphasized, as is an holistic approach to scholarly communication agenda. 相似文献

This study analyzes the predictors of 2 types of media selectivity: interest-based (i.e., choice of entertainment over politics) and partisan (i.e., choice of pro-attitudinal over counter-attitudinal or balanced news). Relying on a large survey-based experiment, we find that issue-specific engagement variables, including perceived issue understanding, issue importance, and issue attitude strength, predict interest-based and partisan selectivity above and beyond the influence of general political knowledge, news interest, and strength of political leanings. These results show that the drivers of selectivity are more complex than general political attributes; rather, they are contextual and reflect people’s engagement with particular issues. 相似文献

IntroductionWhile early commenting on studies is seen as one of the advantages of preprints, the type of such comments, and the people who post them, have not been systematically explored.Materials and methodsWe analysed comments posted between 21 May 2015 and 9 September 2019 for 1983 bioRxiv preprints that received only one comment on the bioRxiv website. The comment types were classified by three coders independently, with all differences resolved by consensus.ResultsOur analysis showed that 69% of comments were posted by non-authors (N = 1366), and 31% by the preprints’ authors themselves (N = 617). Twelve percent of non-author comments (N = 168) were full review reports traditionally found during journal review, while the rest most commonly contained praises (N = 577, 42%), suggestions (N = 399, 29%), or criticisms (N = 226, 17%). Authors’ comments most commonly contained publication status updates (N = 354, 57%), additional study information (N = 158, 26%), or solicited feedback for the preprints (N = 65, 11%).ConclusionsOur results indicate that comments posted for bioRxiv preprints may have potential benefits for both the public and the scholarly community. Further research is needed to measure the direct impact of these comments on comments made by journal peer reviewers, subsequent preprint versions or journal publications. 相似文献

The purpose of this article was to examine the validity of self-reported pedometer steps/day. Forty-seven participants were provided a New Lifestyles NL-2000 (NL-2000; Lees Summit, MO, USA) pedometer and a physical activity (PA) diary for 3 weeks, but not informed of the data-storing capabilities. For weeks 2 and 3, each participant was given a step goal of 3,000 steps/day above week 1 average. A 2 × 3 repeated measures analysis of variance (ANOVA) was used to examine differences between reported steps/day. Bland–Altman plots assessed the mean bias and limits of agreement between reporting methods. Mean self-reported and NL-2000 steps/day were 9,264 ± 3,555 and 8,971 ± 3,590 steps/day (n = 26, p > .05). Mean biases were 216 ± 1,753 (week 1), –506 ± 1,355 (week 2), and –590 ± 1,360 (week 3) steps/day. Negative mean bias values indicate higher self-reported steps/day. Mean steps/day were similar between recording methods, but large differences were observed among individuals, suggesting self-reported steps/day may be valid for PA research at the population level, but not the individual level. 相似文献

There are established links between education and well-being, and between poverty and education. This article draws on interviews with parents of school-aged children impacted by a policy in the UK commonly referred to as the ‘bedroom tax’. A critical psychology perspective to education is put forward, acknowledging the complex interrelationships between psychological well-being, sociopolitical factors and education. 相似文献

Summary Active participation is the foundation of learning through the media of games and simulations. The actual doing by the students
is the important element. Games and simulations, if properly designed and applied, can meet a variety of classroom objectives.
A vast array of educational games and simulations has been designed and many are available commercially. However, a skilled
and innovative instructor can apply certain guidelines to custom design activities for the individual classroom. Involving
students in the design and modification of games and simulations is recommended. 相似文献

Conclusion Garrison’s (2000) review of distance education theories describes the current need for ”sustained real two-way communication
... that refiect(s) a collaborative approach to distance education” (p. 13). One way to apply such theories to research and
coursework is to use collaborative documents to promote transactions culminating in deliberation among the key players. Such
deliberation can create ”a particular kind of democratic public culture among the deliberators: listening as well as talking,
sharing resources, forging decisions together rather than only advocating positions taken earlier, and coming to disagreement”
(Parker, Ninomiya, & Cogan, 1999, p. 129).
Her research interests are collaborative learning in distance education, impact of culture on online learners, and design
of online instruction for constructivist learning environments.
Her primary research interests are in design considerations for collaborative online environments and in the powers of shared
multimedia for enhancing personal growth, multicultural understanding, and global awareness. She investigates visual messages:
how they can be shared and interpreted by learners, their impact, and how their impact can be researched.
Her research interests are in computer and network-based foreign language and cultural learning. 相似文献
