基于信息使用环境理论的引用行为研究:参考文献分析的视角

目前,学术界多开展引用动机和引文功能的相关研究,但对于引用偏好等引用行为却关注较少。基于Taylor的信息使用环境理论,本研究采用参考文献分析方法,全面揭示了施引者引用行为的特征和影响因素。研究将信息使用环境理论中的前三类要素分别通过学者特征、组织环境及论题进行定义,采用参考文献分析法提取第四类要素;随机抽取论文样本,针对上述四类特征进行编码并通过统计分析探讨影响施引者引用行为的因素。研究发现:学者的年龄、性别、教育水平、学术年龄、职业角色、职称、所属机构的类型和层次以及所从事的研究主题和类型,都能对质量、语种、数量、信息资源类型、论文新旧的引用偏好产生显著影响。研究表明:信息使用环境理论和参考文献分析法在引用行为研究中具有适用性。表4。参考文献47。     

数字环境下出版企业4R营销策略研究

面对纷繁海量的媒介内容,受众与媒介作为注意力交换两大主体相互影响,相互作用的过程中,围绕数字化战略平台的4R营销理念:消费者的数字化画像与识别(recognize)、数字化信息覆盖到达(reach)、建立持续关系(relationship)、实现交易与回报(return),出版业与受众互动甚至"互构"增加出版物的社交属性,不断提升的消费者价值是出版业融合与实践的驱动力.     

Attitudes toward Dual Language Immersion Programs in China

With the development of economy and the English learning reform in China,the role of English has increased than ever before.Dual language immersion(DLI)programs,as a new way to offer both languages and content instructions,will gradually take place of traditional English learning and become a new tendency in China.The attitudes of related groups toward the DLI programs are very important to its further development.This paper will first give a brief introduction to the current situation in China,and then analyze the attitude toward DLI programs,includingones of students,teachers and administrators,to find out problems existing in current DLI programs.

Precision measurement of the Newtonian gravitational constant

The Newtonian gravitational constant G, which is one of the most important fundamental physical constants in nature, plays a significant role in the fields of theoretical physics, geophysics, astrophysics and astronomy. Although G was the first physical constant to be introduced in the history of science, it is considered to be one of the most difficult to measure accurately so far. Over the past two decades, eleven precision measurements of the gravitational constant have been performed, and the latest recommended value for G published by the Committee on Data for Science and Technology (CODATA) is (6.674 08 ± 0.000 31) × 10⁻¹¹ m³ kg⁻¹ s⁻² with a relative uncertainty of 47 parts per million. This uncertainty is the smallest compared with previous CODATA recommended values of G; however, it remains a relatively large uncertainty among other fundamental physical constants. In this paper we briefly review the history of the G measurement, and introduce eleven values of G adopted in CODATA 2014 after 2000 and our latest two values published in 2018 using two independent methods.

教师实践智慧的五种常见误解及其澄清——基于循证教育学的视角

关于教师实践智慧的讨论曾存在以下5种观点:(1)教师实践智慧是教师关于如何做的知识、能力或经验;(2)教师实践智慧具有动态性,依赖于具体情境;(3)教师实践智慧具有缄默性,以难以言说的方式而存在;(4)教师实践智慧具有直觉性,通过反思或体验而获得;(5)教师实践智慧具有个人性,难以学习与传播。长期以来,人们似乎已经习惯并认可这些观点。但从循证教育学的视角来看,它们可能是分别针对教师实践智慧的概念、特征、存在方式、生成手段与传播可能性等存在的误解。混淆实践智慧与实践的界限、概念引入的逻辑倒挂以及教育学缺乏操作性定义的研究氛围等,是导致这些误解的重要原因。     

A Meta-Analysis of Single-Case Research on Mathematics Word Problem-Solving Interventions for English Learners with Learning Disabilities and Mathematics Difficulties

This single-case meta-analysis is the first to provide a quantitative synthesis of the published literature on mathematics word problem-solving intervention studies for English learners with learning disabilities and mathematics difficulties. A total of ten single-subject studies were included for analysis. The current study investigated the magnitude of the effect of mathematics interventions targeting the improvement of students’ mathematics word problem-solving performance, and analyzed variables that moderated this effect. Results indicate a moderate overall effect size of 0.81 (95% CI [0.71, 0.90]) on word problem-solving performance for English learners with learning disabilities and mathematics difficulties. Moderator variables such as the implementer of the interventions, instructional focus, and word problem-solving content significantly moderated the mathematics intervention effects.     

动词make的一词多义关系模式初探

一词多义是各种语言中普遍存在的现象。英语中除了术语以外,单义词是很少的,多数的词都是多义词。本文从认知语义学的视角,运用认知语言学的＂原型范畴理论＂以及＂基于理论的多义词分析法＂对动词make进行认知研究,探索构建make一词多义的意义关系模式。
