How far does scientific community look back?

How does the published scientific literature used by scientific community? Many previous studies make analysis on the static usage data. In this research, we propose the concept of dynamic usage data. Based on the platform of realtime.springer.com, we have been monitoring and recording the dynamic usage data of Scientometrics articles round the clock. Our analysis find that papers published in recent four years have many more downloads than papers published four years ago. According to our quantitative calculation, papers downloaded on one day have an average lifetime of 4.1 years approximately. Classic papers are still being downloaded frequently even long after their publication. Additionally, we find that social media may reboot the attention of old scientific literature in a short time.     

发展知识库是提高我国论文被引次数的有效途径

本文以17个论文高产出国家（地区）论文数及被引用次数的数据与ROAR、Open DOAR和RWR三个知识库网站用户注册的知识库数量为依据,得出论文数、论文被引次数与知识库数量之间存在显著相关。并在此基础上,对在RWR网站中17个国家（地区）的知识库排名区间分布进行了统计。研究表明,我国知识库建设,不仅在数量上有较大差距,而且在质量上也处于劣势,提出既要重视知识库理论研究,也要重视知识库实际建设,同时应充分认识知识库开放存取对论文被引的积极作用。     

Ain’t Nobody’s Business If I Do (Read Serials)

Ms. Dorothea Salo, Faculty Associate at the School of Library & Information Studies of the University of Wisconsin-Madison, argued passionately and cogently about the obligation of librarians to protect the privacy of patrons using electronic serials and the data generated from that usage. Libraries should forcefully express their concerns to vendors of such resources about their collection and commercialization of user data and should stipulate provisions in their contracts and licensing agreements to prevent such misuse of patron’s personal information.     

文章立意新颖与逆向思维

写文章都要注意立意，立意就是确立主题。主题的要求除了正确、深刻、集中外，还需要新颖。而使文章立意新颖独特的重要方法之一就是逆向思维。运用逆向思维能使文章立意推陈出新，还能扩大选材范围，而且能培养学生科学的思维品质，使文章在此基础上富有独立性、深化性、创造性。     

《中华人民共和国公共图书馆法》第二十九条解读

图书馆界对《中华人民共和国公共图书馆法》第二十九条第二款形成了两种不同解读。本文从法律文本和图书馆实践出发,通过文义解释、历史解释、目的解释、体系解释、社会学解释方法以及运用比例性原则,对该条文进行法理性解读,并分析在我国公共图书馆法治化过程中该如何对《中华人民共和国公共图书馆法》进行法律解释。     

《广州体育学院学报》2020年载文分析

利用Excel工具和中国知网的计量可视化分析功能对2020年《广州体育学院学报》共6期的载文量、合著关系、基金论文比、作者地区和高产机构分布等方面进行直观的统计分析。结果表明,该刊2020年共刊载学术论文172篇,每期载文量趋于稳定;刊文的合著率62.8%,合著度2.04人/篇,作者之间科研合作意识较强;基金论文比为60.47%,资金资助种类繁多,集中于人文社科领域;发文作者和机构多集中在广东省内甚至是校内,在国内体育领域发挥了一定的影响力,今后可尝试更加开放包容的办刊路径。     

Should citations be counted separately from each originating section?

Articles are cited for different purposes and differentiating between reasons when counting citations may therefore give finer-grained citation count information. Although identifying and aggregating the individual reasons for each citation may be impractical, recording the number of citations that originate from different article sections might illuminate the general reasons behind a citation count (e.g., 110 citations = 10 Introduction citations + 100 Methods citations). To help investigate whether this could be a practical and universal solution, this article compares 19 million citations with DOIs from six different standard sections in 799,055 PubMed Central open access articles across 21 out of 22 fields. There are apparently non-systematic differences between fields in the most citing sections and the extent to which citations from one section overlap with citations from another, with some degree of overlap in most cases. Thus, at a science-wide level, section headings are partly unreliable indicators of citation context, even if they are more standard within individual fields. They may still be used within fields to help identify individual highly cited articles that have had one type of impact, especially methodological (Methods) or context setting (Introduction), but expert judgement is needed to validate the results.     

读图时代新闻摄影的发展策略

在读图时代，新闻摄影的报道方式将被广泛采用，其地位也越来越重要，这是新闻摄影的发展机遇，同时也意味着竞争，如何才能开创自己的特色，独步天下，其发展策略是：第一，新闻摄影必须以其不可替代的本性——典型的瞬间特点，来与其他视图媒介抗衡。第二，新闻摄影应该以其独特的观察角度和新颖的表现形式去创造独家新闻。第三，新闻摄影可以适当地借鉴艺术手法，打造精品图片，使新闻图片像艺术图片那样“好看”“耐看”。     

Disciplinary,Institutional, and Individual Factors Affecting Researchers' Depositing Articles in Institutional Repository: An Empirical Analysis

This research investigates how disciplinary contexts, institutional settings, and individual motivations all affect researchers' depositing their articles into an institutional repository (IR). This study employed the Theory of Planned Behavior as its main theoretical framework and proposed six hypotheses to explain how disciplinary, institutional, and individual factors influence researchers' article depositing behaviors through an IR. This research utilized an online survey as its data collection method, and a total of 221 survey responses from researchers in U.S. academic institutions were collected. The hypothesized relationships were then tested by using multiple regression analysis. This research found that perceived community benefit, perceived institutional support, and perceived career benefit significantly increases researchers' article depositing behaviors through an IR, and the perceived career risk significantly decreases researchers' article depositing behaviors through an IR. This research suggests that community benefit, institutional support, and career issues need to be considered to increase researchers' overall article sharing behaviors through an IR.
