数据驱动范式下政府开放数据状态及其主体行为状态的关系挖掘     

陈玲  段尧清 《图书情报工作》2020,64(2):13-22

[目的/意义] 在数据驱动范式情境下，揭示政府门户网站开放数据状态及其主体行为状态之间的内部关联，推动政府数据开放效果和进程。[方法/过程] 采用爬虫方法抓取上海市政府数据门户网站中各开放数据集，在对各数据集指标进行相关分析的基础上，采用Stepwise探索其回归关系，筛选得出关联度较高的变量；进一步对关系显著的变量进行PLS回归检验，得出政府开放数据状态与其主体行为状态的内部关联。[结果/结论] 在政府数据开放进程中，政府部门的主体行为比数据自身的客体特征对公众主体行为的影响更大。在影响公众评分的因素中，政府开放保密级别的影响因子最大，且具有显著负向影响作用；政府更新频率、政府首次开放时间、数据格式可机读性对公众评分具有显著正向影响作用。  相似文献   

中外情报学论文创新性特征研究   总被引：1，自引：0，他引：1  

曹树金  闫欣阳  张倩  卓伊玲 《图书情报工作》2020,64(1):80-92

[目的/意义] 综合运用定性与定量相结合的方法对近年中外情报学论文的创新性进行分析和对比，揭示情报学领域研究的创新性特征，发现领域学术论文中创新句内部的知识关系，进行更细粒度的论文创新性分析，为研究领域创新点深层次利用提供条件，同时丰富科技论文创新性监测的途径，促进科学研究创新。[方法/过程] 从句子级创新性识别出发，选取中英文各两种情报学期刊作为样本，采用信息抽取和机器学习的方法，将创新句的抽取从现有的摘要扩展到全文，充分利用句子结构和句法特征识别领域创新内容，探讨近年中外情报学论文在创新对象、主题、类别等方面的特征，并做对比分析，最后通过对自动分类的论文集合进行定性的内容分析，总结归纳出中外情报学论文创新的表达范式。[结果/结论] 从创新的表达来看，中外情报学论文创新句的分布情况基本一致，英文期刊论文创新的表达更丰富。从创新性特征来看，英文情报学期刊论文创新主题较集中，而中文主题多样和分散；具体方法的创新是近年情报学领域的创新热点，而在研究方法上创新不足；中英文情报学期刊论文的创新性特点都反映了应用研究、实证研究的成果较多，而理论创新推动缓慢的趋势。  相似文献   

基于专利引用跨越度计量的两国间间接创新合作机会发现     

李睿  青杨媚  范九江 《图书情报工作》2021,64(23):31-39

[目的/意义] 两个国家间的创新合作机会有些是显性直接的，有些是潜在间接的。在此试图构建一种计量和分析专利引用关系的方法，用于发现两国间潜在的间接创新合作机会。[方法/过程] 全球价值链上不同环节专利之间的引用关系中，蕴含着相互衔接、配套的间接合作关系，而不同环节的专利通常具有不同的功能，即IPC存在一定跨越度。因此，设计"专利引用跨越度"指标及算法，用于计量和筛选专利引用网络中"引用跨越度"达到预设阈值的专利引用关系，作为发现间接创新合作机会的基础数据。以新加坡在中国获得授权的发明专利为样本，基于专利引用跨越度计量并配合人工解读和识别，发现中新两国间一系列的间接创新合作机会。[结果/结论] 基于专利引用跨越度计量的两国间间接创新合作机会发现的方法，被实验检验为有效。  相似文献   

政府数据开放中的公众参与模式:理论构建与案例实证     

陈朝兵  简婷婷 《图书情报工作》2020,64(22):58-68

[目的/意义] 探讨政府数据开放中公众参与的理论模式，旨在指导政府部门有效实现公众参与数据开放的政策目标，以及推进政府数据开放中公众参与议题的研究进展。[方法/过程] 采用文献分析法、逻辑分析法和案例分析法，同时以公众参与阶梯理论作为分析工具，构建并实证政府数据开放中的公众参与模式。[结果/结论] 政府数据开放中的公众参与可从理论层面构建为告知型参与、咨询型参与、合作型参与和授权型参与4种模式，其核心涵义分别是政府向公众传达信息、政府咨询公众意见、政府与公众平等合作、政府与公众共同治理。这4种政府数据开放公众参与理论模式一方面在政府意图、主导力量、信息流动、公众信息知晓度和公众自治程度方面存在明显的特征差异，另一方面从国内外政府数据开放公众参与实践案例中获得良好的经验支持。  相似文献   

Performative technologies and teacher subjectivities: A conceptual framework     

Hans Englund  Jonas Gerdin 《British Educational Research Journal》2019,45(3):502-517

Critical educational literature suggests that an increased reliance upon performative technologies is currently transforming the very foundations from which teacher subjectivities are constructed. Arguably though, the number of studies pointing to this risk or tendency is considerably larger than the ones theorising why this should be the case. Further, in those cases where the relationship between performative technologies and teacher subjectivities is theorised, the psychological mechanisms that the technologies appeal to are seldom brought to the fore. Based on this, the purpose of this article is to theorise the psychological mechanisms that performative technologies appeal to and work through, by means of identifying, systematising and elaborating extant understandings of such mechanisms in the critical educational literature. The results are presented in the form of a conceptual framework (referred to as the CMIS-framework) which suggests that one and the same performative technology may play many different roles, where each such role appeals to and works through a particular psychological mechanism. Importantly, depending on the type of psychological mechanism that is appealed to, the CMIS-framework suggests that this will lead to teachers (un)consciously conducting particular forms of subjectivising work upon themselves, here referred to as compliance, mirroring, identification and self-realisation (CMIS).  相似文献   

儒家“五常”思想在大学生创新创业精神培育中的运用     

肖华碧 《清远职业技术学院学报》2020,(2):82-85

中国儒家“五常”思想承载了丰富的创新创业品质。高校创新创业教育应从儒家“五常”思想中汲取精髓,深入挖掘其中有助于培育大学生创新创业教育的思想资源,积极将儒家“五常”思想融入大学生创新创业精神培育的全过程。儒家“五常”思想与大学生创新创业精神培育在修身立业、财富积累、人际交往、终身学习、信誉至上等观念的培养上具有高度的契合性。儒家“五常”思想融入大学生创新创业教育,需要在观念、思想和文化上与时俱进,实现“三个转变”,设置切实可行的实践路径。  相似文献   

Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans     

《Learning and Instruction》2020

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.  相似文献

Lutishoor Salisbury  Jeremy J. Smith  Abayomi Omotola Omolewu 《资料收集管理》2020,45(4):335-353

Abstract

This paper provides a methodology to study the characteristics of the research output from a university department. The faculty publications and their cited references over a 10-year period were used as the basis for this study to identify their publishing patterns and the types of material they are publishing; a core set of journals and other resources they are publishing in and citing over this period; the characteristics of the journals in which they publish and cite; the degree of openness of their publications and their citation advantage; and the age of resources that are referenced.  相似文献

Medieval and renaissance glass technology in Valdelsa (Florence). Part 1: raw materials, sands and non-vitreous finds     

U. Casellato  F. Fenzi  P. Guerriero  S. Sitran  P. A. Vigato  U. Russo  M. Galgani  M. Mendera  A. Manasse 《Journal of Cultural Heritage》2003,4(4):337-353

A significant number of archaeological finds of the 13th–16th century from the Tuscan sites of Germagnana and Gambassi in Valdelsa—FI, was studied by different physico-chemical investigations (SEM–EDS, ICP, Mössbauer spectroscopy, XRD, XRF, TG-DTA) in order to contribute to clarify the production methodology and the pre-industrial glass manufacture technology. The studied samples are mainly non-vitreous finds as production waste, refractory materials, crucibles and raw materials; also vitreous finds as frits, skims, glasses (glass masses, glass working waste and finished products) have been taken into consideration. The obtained petrographic and physico-chemical data strongly suggest that both Gambassi and Germagnana glass manufactures were strictly connected with the sources of vitrifiable materials, situated in Tuscan sand quarries. In particular a comparison between sands from the neighbouring quarries and appropriate finds of the two archaeological sites evidences that the employed vitrifiable materials possibly belong to La Casina La Cava resort. The archaeological classification, based on macroscopic observation and stratigraphic position, was compared and verified with the scientific classification of the examined finds of Germagnana and Gambassi sites based on their composition, morphology and physico-chemical properties.  相似文献
