Letters to the editor on the Zika virus: a bibliometric analysis

Objective:To conduct a bibliometric analysis of Letters to the Editor published on the Zika virus from 1952–2018.Methods:A PubMed search was conducted using the terms (Zika OR ZIKV). Results were limited to 1952–2018 and Publication Type = Letter. Results were exported to EndNote, and the full text of each Letter examined. Each Letter was assigned to one of five categories: Reader Response, Author Reply, Observation, Case Report, or Research. Additional study parameters included number of authors, number of references, use of graphics, and funding. Citation reports were generated for each category and the entire dataset, producing lists sorted by Times Cited.Results:Of 499 Letters, only 15 (3.0%) were published before 2016. In 2016, at the height of the Zika virus epidemic in the Americas, 244 (48.9%) Letters were published, dropping to 145 (29.1%) in 2017 and 95 (19.0%) in 2018. Letters included 149 (29.9%) Reader Responses, 56 (11.2%) Author Replies, 112 (22.4%) Observations, 70 (14.0%) Case Reports, and 112 (22.4%) Research. The Letters were written by 1–35 authors; 369 (74.0%) Letters had 1–5 authors, and 130 (26.0%) had 6 or more. The Letters cited 0–63 references, with an average of 7.0 per Letter. Graphics appeared in 192 (38.5%) Letters, and 77 (15.4%) Letters reported funding. An interesting anomaly was the 104 (20.8%) Letters authored or co-authored by 1 individual.Conclusion:Letters to the Editor remain an important component of scientific communication and may serve as a valuable source of clinical and research information.     

我国高校博物馆研究的评述与展望

本文以CNKI数据库中1956—2021年高校博物馆相关文献为研究对象,通过科学计量工具CiteSpace软件对文献的作者、发文机构、关键词等进行分析,结合相关文献研读后发现,研究的主题主要围绕高校博物馆的建设、定位、藏品和教育功能四个方面;但研究人员和机构合作较少,多为独立研究,且核心问题研究薄弱;根据关键词突现功能分析了我国高校博物馆研究的发展趋势。从合作机制、运营机制、智慧博物馆和科普教育等方面对我国高校博物馆的建设与发展的重要问题进行分析和展望。     

A Bibliometric Snapshot of The Journal of Higher Education and Its Impact on the Field

In recent decades the field of higher education has grown exponentially; however, little research examines a particular journal and its impact on the field. The purpose of this study was to conduct a brief bibliometric analysis and discuss the impact of The Journal of Higher Education (1998–2002), a premier journal in the discipline.     

Geriatric Dentistry:

The fastest growing segment of the American population is the elderly, sixty-five years of age and older. Attention is being focused on the dental health needs of the elderly- the diagnosis, prevention, and treatment of oral diseases and the establishment of geriatric programs to study the problems of aging and provide dental care for the healthy, homebound, and institutionalized. This paper will discuss the increasing importance of geriatric dentistry from a national perspective, the growth of literature of the specialty, and strategies developed to search the National Library of medicine MEDLARS files. A selected bibliography of geriatric dentistry related books, journals, and mongraphs is included in the Appendix.     

有机太阳能电池文献发展态势分析

有机太阳能电池由于价廉、质轻、柔性,受到人们的广泛关注,为全面了解全球科学家对有机太阳能电池的研究概况,本文基于Web of Science数据库,利用Histcite、Bibexcel和Ucinet分析工具对有机太阳能电池研究文献进行计量分析,结果表明：5357篇样本文献刊载在474种期刊上;共有11325位作者、1593个研究机构、80个国家或地区参与研究;2003-2012年是有机太阳能电池研究发展的重要时期;有机太阳能电池研究主要集中于物理学、材料科学、化学研究等36个研究方向,具有一定的跨学科性,研究热点主要为共轭聚合物、有机太阳能电池形态和功率转换效率。在此领域,中国成为仅次于美国的第二大科研产出国。     

文献计量系统的文献-实体关系通用模型研究

针对文献计量系统的共性,回顾文献计量工作的发展历程,阐述文献和学术实体之间的关系,提出文献-实体关系模型。作为文献计量系统的通用模型,文献-实体关系模型能对文献数据的文本进行智能处理,实现半结构化纯文本文献数据向结构化关系数据库格式的完整转换,为文献计量系统的研发奠定基础。     

我国科技报告研究进展与述评

科技报告作为重要的灰色文献,在科技创新中起着重要的作用。文章以CNKI、维普、万方三大数据库为数 据源,以题名和关键词作为检索途径,检索与科技报告相关的文献。通过文献计量和主题分析发现,科技报告论文发 表量相对稳定,2013年尤为明显;科技报告研究者、研究机构集中于图书情报领域,这些研究者和研究机构也是当前 我国科技报告工作的主要实践者;从内容来看,当前科技报告研究集中于国内外科技报告介绍（概念、特点等）、科技 报告加工利用、科技报告体系研究等。     

基于文献计量的科技查新研究现状分析

从文献计量的角度,分析科技查新的研究现状。通过获取核心期刊为来源的相关文献作为样本,对其年 代、机构、作者、关键词分别进行计量与共现分析。研究结果发现：相关研究论文数量有所回落;合作发表的论文较 少且相对封闭;研究主题主要集中在查新报告质量、查新机构现状、创新服务模式等。最后针对存在的问题提出相应 的对策和建议。     

Measuring the scientific publications of double first‐class universities from mainland China

This paper reports a comparative study of the scientific publications of double first‐class universities based on international and domestic Chinese databases from 2006 to 2018. The main results are as follows. Quantitatively, the absolute total number of articles published by Chinese universities has increased. Specifically, the number of international publications in the natural and social sciences from double first‐class universities showed an increasing trend, but the number of domestic journal articles showed the reverse trend. Moreover, based on the number of papers published by each university over the years, we recognized that the ranking changes of universities fall into four categories: rising, declining, stable, and fluctuating. Qualitatively, the international and domestic publications issued by double first‐class universities greatly improved from 2006 to 2018. Moreover, scientific publications, either international or domestic, were unevenly distributed among the double first‐class universities. In general, the double first‐class universities developed rapidly in recent years and play an important role in the development of science and technology in China.
