一流大学建设高校海归教师科研表现自我评价的调查分析

高校海归教师是归国留学人员的重要组成群体,他们知识储备丰富、国际化视野宽广。本研究基于跨文化再适应视角,采用问卷调查的方式,对41所一流大学建设高校的1417名海归教师回国后的科研表现及其主要影响因素进行调查分析。调查结果显示,海归教师对其在课题申报和成果发表方面的评价不高;其在海外学习和工作期间的适应情况、对院系工作氛围的认同程度以及与海外导师、同事或同门开展合作的频率,对海归教师的科研表现具有显著的正向影响。     

Granularity of algorithmically constructed publication-level classifications of research publications: Identification of topics

The purpose of this study is to find a theoretically grounded, practically applicable and useful granularity level of an algorithmically constructed publication-level classification of research publications (ACPLC). The level addressed is the level of research topics. The methodology we propose uses synthesis papers and their reference articles to construct a baseline classification. A dataset of about 31 million publications, and their mutual citations relations, is used to obtain several ACPLCs of different granularity. Each ACPLC is compared to the baseline classification and the best performing ACPLC is identified. The results of two case studies show that the topics of the cases are closely associated with different classes of the identified ACPLC, and that these classes tend to treat only one topic. Further, the class size variation is moderate, and only a small proportion of the publications belong to very small classes. For these reasons, we conclude that the proposed methodology is suitable to determine the topic granularity level of an ACPLC and that the ACPLC identified by this methodology is useful for bibliometric analyses.     

Research universities on the ResearchGate social networking site: An examination of institutional differences,research activity level,and social networks formed

As one of the largest active academic social networking sites, ResearchGate (RG) has been utilized by scholars to share publications, seek collaborators, communicate work in progress, and build scholarly reputation. This study collects data from RG users from 61 U.S. research universities at different research activity levels, as categorized by the Carnegie Classification of Institutions of Higher Education, to examine the impact of institutional differences on RG reputational metrics. The results confirm that RG is a research-oriented academic social networking site that closely and realistically mirrors the research activity level of institutions. With an increase in the research activity level of a university, its affiliated RG users tend to have higher RG scores, more publications and citations, and more profile views and followers, while the average number of reads of their publications and followees tend to be lower and fluctuant. In addition, RG users primarily follow others from institutions of a higher research activity level, forming virtual social networks centered around esteemed institutions. The study suggests academic social networks can serve as indicators in evaluation of research activities among research institutions, and such sites can be helpful and credible for acquiring resources, keeping informed about research, and promoting academic influence.

基于标记树的XML文档自动分类研究

本文首先介绍了XML文档和DTD标记树的生成方法,并对标记树中节点的概念进行了扩充,使之不但包括元素,同时也包括连接符,以适应DTD结构的要求。随后将标记树中的元素分为共有元素、文档元素和DTD元素,并提出层次权重和结构权重以衡量元素的层次和结构复杂程度,给出具体计算方法。在此基础上提出了一个衡量XML文档和DTD之间相似度的算法,将其应用于XML文档自动分类中,并给出该算法的时间复杂度计算公式。从实验结果可以看出,该分类方法准确率较高。     

基于模糊综合评判方法的仰光河航道安全评估

应用模糊综合评判方法,分析仰光河航道的航道安全.将仰光河航道分成4个航段进行研究,考虑缅甸航运业的发展以及航道进出船舶的安全,对全部航道和每一段航道进行安全分析,基于航道情况、环境因素等,提出航道的模糊综合评判方法.该综合评判方法可以定量表示全部航道和每一段航道的危险度.     

论教师的专业境界

教师是学校持续发展的第一资源。研究教师专业素养的目的是确保教育质量。从教师个性特征、教师知识、教师职业道德、教师教育教学技能等方面展开了研究。但是,教师是否把专业活动理解成是实现人生价值的过程,深刻地影响着教师的教育活动质量。由此,提出重视教师境界有了现实意义。
