An important current challenge for research information providers is ensuring the automated discovery of Open Access (OA) content in hybrid journals. We found no evidence of discovery services that are able to systematically identify the crucially important free full-text availability of OA articles regardless of where and how such articles have been published (i.e., in fully OA journals or in hybrid journals). A solution is important because hybrid journals are proliferating and consequently the chances of missing OA articles is real and is happening. Nearly all of the major publishers now provide such journals in order to take advantage of recent changes in research funder requirements, and to be competitive in the new OA business model. By working with a group of scholarly publisher partners and by using standard metadata elements that publishers are already familiar with, we show a systematic and standardized manner to identify OA at the article level. Our proposal is to embed OA-related elements in the metadata freely exposed by publishers for aggregators and discovery services. For example, in the Table of Content (TOC) Really Simple Syndication feeds the publishers use to announce new journal issues and content. Based on the initial results obtained, we discuss the capabilities of our solution, and evaluate the impact produced by our application in the systematic discoverability of OA content from the participating hybrid journals, using an implementation done with the freely available journal current awareness service—JournalTOCs.  相似文献

Feminist Criticism,for women, is described as an self-awakening, and self-improvement.It is the voice of Feminism.By taking it,feminism breaks through the patriarchy-centered so-cialism.This paper analyses the story A Rose for Emily from a feminist perspective,explores the social roots that lead to the tragedy of Emily, and points out that Emily is victimized by the male-centered society and the southern conventional moral standards.  相似文献

This paper provides a review of school leadership preparation and development in Australia through considering the requirements for becoming a principal, how leadership preparation and development occurs, and consideration of recent developments to provide an Australian standard for school leaders. Australian educators have relied mostly on a self-identification and self-managed system in which individuals decide that they want to pursue leadership opportunities and then seek out the support and experiences to help them. Support is available and provided through system, university, and service organization programmes, and the support of colleagues and senior leaders in schools. Whilst there is an extensive range of support provided by systems, universities and service organizations, there is little evidence of their impact on schools. At the school level there needs to be far greater support in identifying and developing leaders. Developments in creating a national leadership standard might lead to some type of credentialing programme that could allow individuals to benchmark their development, and ensure that preparation and support programmes are of the highest quality. An alternative view is to reinforce greater individual responsibility for leadership development and career progress, encourage schools and systems to focus less on individual leadership and more on collective leadership, and consider more innovative ways of providing leadership development.  相似文献

Novice members of a Norwegian national rater panel tasked with assessing Year 8 pupils’ written texts were studied during three successive preparation sessions (2011–2012). The purpose was to investigate how the raters successfully make use of different decision-making strategies in an assessment situation where pre-set criteria and standards give a rather strict framework. The data sources were the raters’ pair assessment dialogues. The analysis shows that the raters use a ‘shared standards strategy’, but when reaching agreement on text quality they also seem to make very good use of assessment strategies related to their work as writing teachers. Moreover, asymmetries in knowledge and participation among raters contribute to creating an image of writing assessment as a challenging hermeneutic practice. It is suggested that future rater preparation would gain from being attentive to the internalised assessment practices teachers bring to the fore when working as raters.  相似文献
