高职院校辅导员促进学风建设的几点思考

在这个充满诸多干扰的时代,高校学风普遍存在着一些问题,特别是高职院校。本文在探讨了高职院校学风的主要问题及分析引发其成因的基础上,从辅导员的角度来谈如何改善高职院校学风的几点思考。     

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.     

旅游管理本科专业实践教学改革探析

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.     

我国图书情报领域期刊论文的科学数据引用特征研究

[目的/意义] 探索期刊论文科学数据引用特征与规律不仅有助于描述学科领域对科学数据的利用情况，还能够揭示学术成果表达中的数据引用模式。[方法/过程] 以我国图书情报领域6种期刊2017年与2018年第一期刊载论文为样本，结合国家标准《信息技术科学数据引用》的引用元素，采用内容分析法从9个维度对样本论文的科学数据引用行为进行数据编码，应用统计学方法描述图书情报领域期刊论文科学数据引用特征并探索不同维度特征间的关联关系。[结果/结论] 图书情报领域期刊论文广泛引用来自国内外的统计整理类科学数据，对期刊论文中个人研究科学数据的引用量较大；科学数据引用标注方式与科学数据类型存在一定对应关系，但多样化的标注方式缺乏统一性；二手引用现象较为突出，二手引用程度与科学数据创建者类型相关。     

基于用户兴趣度量的知识发现服务精准推荐

[目的/意义]针对当前知识发现服务中存在的个性化程度不高和推荐效果不佳等问题，提出一种基于用户兴趣度量和内容分析的推荐算法。[方法/过程]文章通过特征词分布、LDA主题分布、引文结构网络三个维度构建学术资源模型，并通过对用户行为的度量，计算用户对其浏览学术资源的兴趣度，结合学术资源模型构建用户兴趣模型。将用户兴趣模型与学术资源模型匹配，计算其相似度，得到用户对每条学术资源的兴趣值，最后将兴趣值最高的TOP-N学术资源推荐给用户。[结果/结论]通过实验检验算法的有效性和推荐准确率，结果显示，本文从实时动态度量兴趣的角度，提出的推荐算法能较好地预测用户兴趣，推荐效果显著，为实现发现服务精准推荐提供思路。     

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。     

The Effect of Visual‐Chunking‐Representation Accommodation on Geometry Testing for Students with Math Disabilities

Students who struggle with learning mathematics often have difficulties with geometry problem solving, which requires strong visual imagery skills. These difficulties have been correlated with deficiencies in visual working memory. Cognitive psychology has shown that chunking of visual items accommodates students’ working memory deficits. This study investigated the effects of visual‐chunking representation as a testing accommodation for improving students’ geometry problem‐solving performance. Participants were four third‐graders with difficulties in mathematics. An adapted reversal design was employed to examine the students’ performance changes during standard testing conditions and accommodated testing conditions. During the accommodated condition, students were presented with visual‐chunking images. Results suggested that the visual‐chunking representation accommodation improved students’ performance on geometry problem‐solving tasks, and an interview confirmed students’ preference for the visual‐chunking representation approach.     

加强实践教学,提高应知应会能力

自制实验器材,加强实践教学,利用一切有利环境。条件增加电工实验实习。使学生真正能够做到理论联系实际,提高其实际操作技能和应变能力,从而成为合格的"应用型"技术人材。十年来我们在电工类的教学改革中,做了一点初步尝试,取得了一定的效果。
