Studies related to the prevention and control of myopia in adolescents have increased rapidly, but only a few have measured the levels of scientific collaboration among authors, institutions and countries in this field. Thus, in this study, we aimed to reveal the status and levels of scientific collaboration in this field.
The research population included all published papers in the field of adolescent myopia prevention and control indexed in the Web of Science databases from 1997-2016. The co-authorship networks were drawn using SATI (Statistical Analysis Toolkit for Informetrics), Ucinet and VOS viewer (Visualisation of Similarities viewer). Active authors and some measures of co-author network, including degree centrality, closeness, betweenness, density and diameter, were also assessed.
Overall, 610 records were obtained, and a number of publications developed through an increase in different collaboration types, with cooperation among authors and institutions as the most apparent ones. The top ten active authors and institutions were identified. The density of cooperative networks of the top 70 authors and the first 69 institutions were 0.043 and 0.011, respectively, with corresponding diameters of five and six, respectively. Seven distinct clusters formed the cooperation network among 38 countries. The top three clusters were centered in China, the United States and Australia, also identified as the most productive countries.
The flow of information is slow and the collaboration among authors and institutions in the network are not close enough. Thus, multiple collaboration types should be encouraged in this field, especially among countries.
与青少年近视防控相关的研究迅速增加,但只有少数研究测量了该领域作者、机构和国家之间的科学合作水平。因此,在本研究中,我们旨在揭示该领域科学合作的现状和水平。
研究人群包括1997 - 2016年科学引文索引数据库中收录的所有青少年近视防控领域的已发表论文。使用SATI(信息计量学统计分析工具包)、Ucinet和VOS viewer(相似性可视化查看器)绘制共同作者网络。还评估了活跃作者以及共同作者网络的一些指标,包括度中心性、接近性、中介中心性、密度和直径。
总体而言,共获得610条记录,许多出版物通过不同合作类型的增加而发展,作者和机构之间的合作最为明显。确定了前十位活跃作者和机构。前70位作者和前69个机构的合作网络密度分别为0.043和0.011,相应直径分别为5和6。38个国家之间的合作网络形成了7个不同的集群。前三大集群集中在中国、美国和澳大利亚,这三个国家也被确定为产出最多的国家。
信息流动缓慢,网络中作者和机构之间的合作不够紧密。因此,该领域应鼓励多种合作类型,尤其是国家之间的合作。
