This study proposes a temporal analysis method to utilize heterogeneous resources such as papers, patents, and web news articles in an integrated manner. We analyzed the time gap phenomena between three resources and two academic areas by conducting text mining-based content analysis. To this end, a topic modeling technique, Latent Dirichlet Allocation (LDA) was used to estimate the optimal time gaps among three resources (papers, patents, and web news articles) in two research domains. The contributions of this study are summarized as follows: firstly, we propose a new temporal analysis method to understand the content characteristics and trends of heterogeneous multiple resources in an integrated manner. We applied it to measure the exact time intervals between academic areas by understanding the time gap phenomena. The results of temporal analysis showed that the resources of the medical field had more up-to-date property than those of the computer field, and thus prompter disclosure to the public. Secondly, we adopted a power-law exponent measurement and content analysis to evaluate the proposed method. With the proposed method, we demonstrate how to analyze heterogeneous resources more precisely and comprehensively. 相似文献

近年来,中国社会的思想文化和价值观念都发生了深刻变化,境外的个人利己主义、极端个人主义、自我中心主义等逐渐进入人们的意识形态之中,在社会上形成了一种多元价值观并存的格局。在校大学生阅读价值的多元化,不仅反映了他们多层次的人生价值诉求,同时也在一定程度上体现了其价值观的多元化。只有对我国在校大学生多层次的阅读需求进行正确引导,才可能在多元价值观的冲突与调适中真正实现他们的阅读价值。 相似文献

多源流分析框架是美国政策家约翰.W.金登提出的一种政策分析方法,他认为整个系统中存在着三股源流,即问题流、政策流和政治流,而＂政策之窗＂对三者起了耦合作用。推动1999年我国高等教育扩招政策出台的＂问题流＂主要是1997年亚洲金融危机,＂政策流＂是著名学者对发展高等教育的理论探索,＂政治流＂是我党对教育公平的关注,＂政策之窗＂便是金融危机的爆发以及汤敏夫妇的建议。扩招政策的出台促进了教育公平,推动了高等教育的发展,但是与之同时,也带来了一系列问题。各部门要采取有力措施,更加关注效益和质量。 相似文献

This paper attempts a direct comparison of the available alternative channels that can be employed in a cross media publishing
scheme. More precisely it examines the content, the publishing speed, and the rhythm of the publishing channels. Interesting
conclusions are drawn concerning the characteristics of each channel. A new publishing channel is proposed in order to allow
newspapers to directly compete with radio and TV channels. 相似文献

Business English professional \"Integration in Multiple Certificates\" refers to these two kinds of certificates——a diploma and vocational certificates. Business English curriculum design unified vocational qualification certificate with professional training objectives. Basis on the meeting of requirements of certificates for graduation, making professional training contents, curriculum,teaching methods together with vocational training and the requirements of professional qualification certificates. 相似文献

Abstract In this article, we suggest an instructional intervention to help students understand statements involving multiple quantifiers in logical contexts. We analyze students' misinterpretations of multiple quantifiers related to the ϵ-N definition of convergence and point out that they result from a lack of understanding of the significance of the order of the quantifiers in the definition. We introduce the Mayan activity which is designed to cause and then to help resolve students' cognitive dissonance. In particular, the Mayan stonecutter story in the activity is presented in an understandable and colloquial form so that students can recognize the independence of ϵ from N in the ϵ-N definition. Consequently, the Mayan activity can be regarded as a useful instructional intervention to study statements related to the ϵ-N definition of convergence. 相似文献

In consideration of the potential of drawing and writing as assessment and learning tools, we explored how early primary students used these modes to communicate their science understandings. The context for this study was a curricular unit that incorporated multiple modes of representation in both the presentation of information and production of student understanding with a focus on the structure and function of carnivorous plants (CPs). Two science teacher educators and two first-grade teachers in the United States co-planned and co-taught a multimodal science unit on CP structure and function that included multiple representations of Venus flytraps (VFTs): physical specimens, photographs, videos, text, and discussions. Pre- and post-assessment student drawings and writings were statistically compared to note significant changes, and pre- and post-assessment writings were qualitatively analysed to note themes in student ideas. Results indicate that students increased their knowledge of VFT structure and function and synthesised information from multiple modes. While students included more structures of the VFT in their drawings, they were better able to describe the functions of structures in their writings. These results suggest the benefits for student learning and assessment of having early primary students represent their science understandings in multiple modes. 相似文献

This study was carried out with 1,857 poor children from 17 schools, living in low-income areas of Dar Es Salaam, Tanzania. All children took the ‘Student Multiple Intelligences Profile’ (SMIP) questionnaire as part of a bigger project that gathered data around concepts and beliefs of talent. This paper sets out two aims, first to investigate the structural representation of the self perceived multiple intelligences for this set of children and second to discuss how the best fit model might reflect children’s culture and their school experiences. After carrying out exploratory factor analysis, a four factor first order model was shown to have a good fit. A higher order factor solution was investigated owing to the correlation of two latent constructs. In order to provide some insight into the multiple intelligences construct the relationship between the SMIP items, student test outcomes and attitudes to learning were examined. The item groupings were explored through African cultural beliefs around intelligences indigenous to African communities. 相似文献
