Topic evolution has been described by many approaches from a macro level to a detail level, by extracting topic dynamics from text in literature and other media types. However, why the evolution happens is less studied. In this paper, we focus on whether and how the keyword semantics can invoke or affect the topic evolution. We assume that the semantic relatedness among the keywords can affect topic popularity during literature surveying and citing process, thus invoking evolution. However, the assumption is needed to be confirmed in an approach that fully considers the semantic interactions among topics. Traditional topic evolution analyses in scientometric domains cannot provide such support because of using limited semantic meanings. To address this problem, we apply the Google Word2Vec, a deep learning language model, to enhance the keywords with more complete semantic information. We further develop the semantic space as an urban geographic space. We analyze the topic evolution geographically using the measures of spatial autocorrelation, as if keywords are the changing lands in an evolving city. The keyword citations (keyword citation counts one when the paper containing this keyword obtains a citation) are used as an indicator of keyword popularity. Using the bibliographical datasets of the geographical natural hazard field, experimental results demonstrate that in some local areas, the popularity of keywords is affecting that of the surrounding keywords. However, there are no significant impacts on the evolution of all keywords. The spatial autocorrelation analysis identifies the interaction patterns (including High-High leading, High-Low suppressing) among the keywords in local areas. This approach can be regarded as an analyzing framework borrowed from geospatial modeling. Moreover, the prediction results in local areas are demonstrated to be more accurate if considering the spatial autocorrelations. 相似文献

The present study aims to investigate the role of rankings in Kazakhstani higher education policy and their influence on a group of national universities in Kazakhstan. The analysis draws attention to the role of the Kazakhstani government and accreditation agencies in developing coercive and normative isomorphism in Kazakhstani higher education. The analysis of university missions and development strategies of a group of universities with a special status has revealed that national universities are pushed towards an Anglo-American model of a research university. Further research is suggested to assess the response of Kazakhstani higher education institutions (HEIs) to these coercive and normative pressures. 相似文献

Much has been studied regarding university reforms and their impacts on scientific development worldwide. This paper aims to enrich current perspectives on university reform by developing a distinct concept of social science development in the context of the emergence of academic social sciences in Indonesia. Using a bibliometric method, this paper finds a significant increase in the volume of international scientific publications focusing on socio-economic and political issues. However, two issues that presently color the landscape of social scientific publications are the bifurcation of academic dependencies and limited extension of Western social theories. The future of the social sciences in Indonesia will be determined by interrelationships between the state, universities, and networks of academics who can address the former issue and ensure that academics publish in mainstream international journals emphasizing the prominence of the latter. In doing so, the social sciences will have the potential to improve future university teaching and engagement in public policymaking in Indonesia. 相似文献

In this paper, we utilise the theoretical concept of ‘boundary crossing’ to explore how, as Australian university teacher educators, we worked with library curators and a class of student teachers to mount a public exhibition of their group work. We consider how the students crossed ‘boundaries of imagination’ in symbolic representation and critical analysis by creating artistic installations to express global education themes. We reflect on what we, the university educators, learned about crossing institutional and pedagogical boundaries to mutually facilitate new learning. We argue for the importance of shared public pedagogy as offering new avenues for teacher education and of connecting with local communities. 相似文献

成果导向是芬兰学校体育质量监测依据的主要理念。芬兰学校体育质量监测机构与政府没有隶属关系,监测人员可分为报告质量、体育课程质量、体育教师质量、体育教学质量、体育设施质量6种监测类型;监测人员经过严格的选聘程序、分类化的专业培训之后,可以根据成果导向的学生体育学习监测框架,从省级、县级、区级3个不同层面开展监测工作,监测程序由政府进行认证与规范。成果导向的芬兰学校体育质量监测结构由早期、中期、后期、执法、突击与合并6种监测类型及其相应的指标和内容构成,各类型之间环环相扣、相互补充。通过借鉴芬兰经验,突出成果导向,有利于提升学校体育质量,强化我国学校体育督导的目标性与规范性,有助于优化与改善我国学校体育质量的现有督导结构及运行机制,使其更加关注学校体育成果细化和转化的导向,促使督导评估指标朝向可测化和具体化方向发展,进而更好地发挥督导成果在助力学校体育发展方面的各类功能。 相似文献
