网刊元数据自动提取和PDF文件自动分割实践——以“中西医结合护理”网站为例

以《中西医结合护理》排版所用的方正书版文件为例,介绍用于圈定元数据字段的“准标签对”的选择技巧,以及fbd文件与html文件之间的字符兼容性和格式对等性的处理方法.以此为基础,可以方便地实现高质量网刊元数据的高效率自动提取,以及PDF文件的精准自动分割与转页合并.实践证明,对于特定期刊而言,上述工作是很容易自主完成的.     

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.

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.     

“自媒体”时代高校青年网络行为与引导策略研究

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.
