It has been shown (Lawrence, S. (2001). Online or invisible? Nature, 411, 521) that journal articles which have been posted without charge on the internet are more heavily cited than those which have not been. Using data from the NASA Astrophysics Data System (ads.harvard.edu) and from the ArXiv e-print archive at Cornell University (arXiv.org) we examine the causes of this effect. 相似文献

A two-year randomised controlled trial of peer tutoring in mathematics using the Duolog Math technique was operated in 80 schools. The aim was to achieve adequate implementation quality with modest pre-intervention training for teachers, who received brief didactic training and no process feedback (but they were to train pupils using modelling, practice and feedback). Implementation integrity was observed in Year 1 in 29 randomly selected schools; in Year 2 in 30 randomly selected schools. In both years some observed variables of class-wide context and individual technique were high; however, some were lower. There were deficits in: teachers introducing the problem, suggesting ways to concretise the problem and holding plenary sessions. Crucially, there was very little summarising or generalising. Thus, implementation was partial in both years, but better in Year 2. The implications for future intensity of training are explored. 相似文献

The Open Access movement of the past decade, and institutional repositories developed by universities and academic libraries as a part of that movement, have openly challenged the traditional scholarly communication system. This article examines the growth of repositories around the world, and summarizes a growing body of evidence of the response of academics to institutional repositories. It reports the findings of a national survey of academics which highlights the conflict between the principles and rewards of the traditional scholarly communication system, and the benefits of Open Access. The article concludes by suggesting ways in which academic libraries can alleviate the conflict between these two paradigms. 相似文献

School leadership has been well researched in developed countries. However, in Asia, particularly in Indonesia, school leadership has not been well explored. Using survey data from a sample of 475 teachers in six Lampung school districts, this paper examines the relationships between school principal leadership styles and school principal decision-making styles in an Indonesian school context. Findings are that most of the relationships between school principal leadership styles and school principal decision-making styles are significant. These findings suggest that teachers perceive that principals should exhibit much more transformational leadership style and rational decision-making style but avoid laissez-faire leadership style and avoidant decision-making style. 相似文献

Education for sustainable development aims to help learners engage with the concept of sustainability. This paper considers whether specific values-centred sustainability training techniques can promote personal engagement with sustainability when undertaken by higher education students on an extra-curricular voluntary basis. Conducted over an eight-month period, the study evaluates the impact of the training on 67 second year undergraduate design and engineering students at Plymouth University using pre- and post-training values and worldview scales measured against a control group. Four months after the training, one-to-one interviews were conducted with a subset of the sample. A quantitative analysis of the values and worldview surveys indicates that a degree of values clarification and mind-set shift resulted from the training, with design students appearing more receptive than those studying engineering. This finding was reinforced in the interview data, which illustrates where and how learners engaged with the training and provides examples of learners deep thought, reflection and mind-set changes. 相似文献

This research in New Zealand, based on the multiple constituencies model, identified key performance indicators in university libraries as perceived by six separate stakeholder groups. Ranked lists and correlations between the lists show similarities, but also confirm that stakeholder groups have different perspectives on library effectiveness. 相似文献

The juvenile justice system established in Scotland in 1971, in which lay volunteers play a central part, provides a framework for making decisions about children in need of care and protection as well as those who have committed delinquent acts. Although cases of child abuse and neglect have come increasingly to the attention of children's hearings in recent years, they nevertheless constitute a small fraction of a workload dominated by cases of delinquency and truancy. A recent Scotland-wide study of the hearings system therefore gave only limited attention to the processing of abuse and neglect referrals. As a step towards rectifying this imbalance, a separate enquiry was carried out in 1981, when 43 such hearings were systematically observed and the participating panel members interviewed. Examination of these results indicates a heavy dependence on social workers' recommendations, a reluctance to open up sensitive areas for discussion, even though these may be of central importance, and an apparent lack of curiosity about the arrangements made for children removed from their homes, and the implications of these. In general, it is concluded that the anxiety generated by child abuse and neglect has prevented panel members from recognizing the distinctive features of their role in the decision-making process and has led them to fall back on an inappropriate model of practice derived from delinquency hearings. An alternative model is outlined. 相似文献

This paper examines how innovation-related capabilities for production, design and marketing develop at the subsidiary level within multinational enterprises (MNEs). We focus on how subsidiary autonomy and changing opportunities to access external (host country) sources of capability contribute to the accumulation of specialist capabilities in five Taiwan-based MNE subsidiaries in the semiconductor industry. Longitudinal analysis shows how the accumulation process is subject to discontinuities, as functional divisions are (re)opened and closed during the lifetime of the subsidiary. A composite set of innovation output measures also shows significant variations in within-function levels of capability across our sample. We conclude that subsidiary specialisation and unique subsidiary-specific advantages have evolved in a way that is strongly influenced by the above factors. 相似文献
