Dimensions is a partly free scholarly database launched by Digital Science in January 2018. Dimensions includes journal articles and citation counts, making it a potential new source of impact data. This article explores the value of Dimensions from an impact assessment perspective with an examination of Food Science research 2008–2018 and a random sample of 10,000 Scopus articles from 2012. The results include high correlations between citation counts from Scopus and Dimensions (0.96 by narrow field in 2012) as well as similar average counts. Almost all Scopus articles with DOIs were found in Dimensions (97% in 2012). Thus, the scholarly database component of Dimensions seems to be a plausible alternative to Scopus and the Web of Science for general citation analyses and for citation data in support of some types of research evaluations.  相似文献

GDP本来是一个表征财富的普通符号,然而,一个时期以来,作为财富象征符号的GDP却成了人们竞相追逐并加以炫耀的对象,甚至成为国家的最高目标。于是,作为人们崇拜对象的GDP反过来异化为人们的主宰,步入一条反和谐的不归之路。在内建和谐社会、外促和谐世界的大背景下,在失衡之路上狂奔的GDP必须回归和谐,确立新的和谐GDP理念。和谐哲学为和谐GDP提供了理论可能性,而和谐社会建构实践的展开为和谐GDP奠定了坚实的推广基础。作为和谐GDP三个维度的和谐产出、和谐分配与和谐消费,彰显了GDP的和谐向度。和谐GDP的“三和”之维.有利于营造出和谐心态、和谐世态与和谐生态,使和谐GDP客观上成为和谐社会的理想经济形态。  相似文献

Big and open linked data are often mentioned together because storing, processing, and publishing large amounts of these data play an increasingly important role in today's society. However, although this topic is described from the political, economic, and social points of view, a technical dimension, which is represented by big data analytics, is insufficient. The aim of this review article was to provide a theoretical background of big and open linked data analytics ecosystem and its essential elements. First, the key terms were introduced including related dimensions. Then, the key lifecycle phases were defined and involved stakeholders were identified. Finally, a conceptual framework was proposed. In contrast to previous research, the new ecosystem is formed by interactions of stakeholders in the following dimensions and their sub-dimensions: transparency, engagement, legal, technical, social, and economic. These relationships are characterized by the most important requisites and public policy choices affecting the data analytics ecosystem together with the key phases and activities of the data analytics lifecycle. The findings should contribute to relevant initiatives, strategies, and policies and their effective implementation.  相似文献

把分形维数理论应用到数字水印中,提出了基于Chebysher混沌置乱和分形维数的自适应数字图像水印算法。首先将载体图像分块,计算每个小块的分形维数。然后将载体图像进行分块DCT变换,使用改进的邻域平均法,将经过混沌置乱后的水印信息嵌入到图像的DCT域中,并根据该小块的分形维数调节嵌入强度,实现了水印信息的自适应嵌入。提取水印时,实现了完全盲提取。MATLAB仿真结果表明,该算法具有较好的不可见性,对常见的图像处理攻击具有较好的鲁棒性。  相似文献

认知语言学是以人对世界认知为基础的,重在对语言现象进行解释的一门新兴学科。本文仅从范畴化、概念隐喻、意象维度、像似性这些人的认知能力或机制来说明翻译过程其实是个认知过程,并以这些认知能力或机制试图对翻译中的原文理解,译文表达,文化介入及审美运用等现象概括到认知上的统一解释。  相似文献

如何把文学批评融入英美文学课程教学,是当下亟需解决的一个问题。融入文学批评不仅要考虑到文学批评的维度,还要考虑到教学目标设计的维度。以文本、语境和批评为知识维度,以记忆、理解、应用、分析和创造为能力维度,构建英美文学课程教学目标矩阵,可为具体文学教学目标设计提供参考框架。  相似文献

Those who study social networks encounter an all-too-often conundrum in academia: the richness of data sets coupled with methodological complications. This article highlights three of the most salient issues facing social network scholars and potential ways of overcoming them. By discussing the quantitative measurement of the network in question, the specific variables under examination, and the overall goal(s) of the research project, readers will understand both the costs and rewards associated with an area of communication, psychology, and sociology scholarship that has existed and thrived for more than a half century.  相似文献

CLIL(Content and Language Integrated Learning)是双语教学在欧盟非英语国家的别称。它承袭了加拿大"浸入式"教学理念,将外语作为非语言学科的教学语言,使语言与学科在教学过程中共同发挥作用。外语不仅是学习的内容,还是学习的工具,实现了由孤立单纯的外语教学向外语与不同学科知识相结合的教学模式发展。本文通过对欧盟非英语国家的CLIL研究综述,对其教学框架与策略的梳理,希望为我国EFL教学长期面临的教学效果不佳、无法与双语教学进行有效过渡的问题提出一些建议。  相似文献
