Highly cited publication performance in the ophthalmology category in the Web of Science database:a bibliometric analysis

AIM:To determine and evaluate the features of highly cited articles(HCAs)in the ophthalmology category in the Science Citation Index Expanded(SCI-EXPANDED)from 1991 to 2020.METHODS:The Web of Science Core Collection documents with at least 100 citations from their publication year until December 31,2020,were evaluated as highly cited.The examined features were the distribution of yearly output and its average number of per publication,HCAs,authors,institutions,journals,and nations.The publication performance of nations and organizations was assessed using six publication indicators.The Y-index was employed to compare the research outputs of various authors.RESULTS:Publications that had cited the most references were highly published in high-impact factor journals.The United States of America came out on top across all six publication indicators,and it was home to eight of the top 10 most productive institutions.The articles written by Breivik et al(2006)and Farrar et al(2001)were highly cited and had a significant impact in 2020.The authors had a higher number of highly cited articles published as corresponding authors than as first authors.CONCLUSION:The findings of the present study highlight the current scope of global research in ophthalmology.The findings can help policy-makers and advisory groups of research centers to develop future policies.In addition,the findings can guide researchers in this field.

中国人才政策研究的现状与趋势——基于Cite Space的可视化分析

科学的人才政策是实现人才强国和科教兴国战略的重要保障。借助Cite Space量化分析软件,分别从发文作者、发文机构、高被引文献、关键词等方面对人才政策研究情况进行可视化分析,在整合既有研究基础上展望未来。研究表明:我国人才政策研究主要聚焦于人才政策本身、实施存在的问题、可行性路径三个维度。当前的研究热点主题为人才战略、人才开发、人才培养,已有关键词之间关联性不强,机构合作密度不高,缺少系统研究框架和强大理论支持。据此,今后人才政策的研究应该加强跨学科融合思考,建构具有中国特色的本土化研究架构,注重人才培养的硬环境和软环境建设。

Tendency and foci of nurse practitioners:bibliometric analysis based on the CiteSpaceV

Objective:Nurse practitioners(NPs)have drawn significant attention recently and played a major role in healthcare.We aim to find the evaluation of NPs through published studies and then visualize the research status and hotspots in this field.Methods:All data came from the Web of Science Core Collection,and the data were counted and entered into Excel 2016.The key documents nodes were excavated by analyzing the knowledge network map using Cite Space V software.In this study,these nodes of“author,country,institution,keyword,co-citation(referencecited-authorcited-journal),and grant”were harvested for analysis and comparison.Results:A total of 4912 records,which were published between 2007 and 2018 and pertained to NPs,were retrieved from the Web of Science Core Collection database(Wo SCC)from a diversity of languages.The total and the annual number of publications and citations of these continually increased over time.Most publications were in 2018(618 records).This study involved 8241 authors located in 98 countries and 4557 institutions totally.The United States(2737 records)and the University of Michigan(90 records)dominated in publication frequency.There are 902 journals and 2449 articles with funding support that have been analyzed.Most articles were from JAMA:The Journal of the American Medical Association(1386,IF=47.661),followed by the Journal of Advanced Nursing(1359,IF=2.267),and The New England Journal of Medicine(1109,IF=79.258).The reference“The Role of Nurse Practitioners in Reinventing Primary Care”was co-cited most frequently,which revealed it as the highest landmark article in NP.The top-ranked keyword was“Care,”other than“Nurse practitioner,”which has an ultra-high frequency.Some of the high-frequency keywords represent the significant direction of NPs.Conclusions:NPs are at the crux of health-care delivery and play an important role in providing high-quality nursing.Publications on NPs in Wo SCC have increased notably during the recent years,and have appeared in some journals that have a high impact factor.Research frontiers and developmental trends were revealed by the analysis in this study,which can be used to forecast future research developments in NPs and taken as a reference to choose the right directions by subsequent researchers who wish to use these results.However,the grant support from administration or research institutions is still in need of improvement and the scope of research in NPs should be broadened in the future.

Functions of Uni- and Multi-citations： Implications for Weighted Citation Analysis

Purpose： （1） To test basic assumptions underlying frequency-weighted citation analysis： （a） Uni-citations correspond to citations that are nonessential to the citing papers; （b） The influence of a cited paper on the citing paper increases with the frequency with which it is cited in the citing paper. （2） To explore the degree to which citation location may be used to help identify nonessential citations. Design/methodology/approach： Each of the in-text citations in all research articles published in Issue 1 of the Journal of the Association for Information Science and Technology （JASIST） 2016 was manually classified into one of these five categories： Applied, Contrastive, Supportive, Reviewed, and Perfunctory. The distributions of citations at different in-text frequencies and in different locations in the text by these functions were analyzed. Findings： Filtering out nonessential citations before assigning weight is important for frequency-weighted citation analysis. For this purpose, removing citations by location is more effective than re-citation analysis that simply removes uni-citations. Removing all citation occurrences in the Background and Literature Review sections and uni-citations in the Introduction section appears to provide a good balance between filtration and error rates. Research limitations： This case study suffers from the limitation of scalability and generalizability. We took careful measures to reduce the impact of other limitations of the data collection approach used. Relying on the researcher＇s judgment to attribute citation functions, this approach is unobtrusive but speculative, and can suffer from a low degree of confidence, thus creating reliability concerns. Practical implications： Weighted citation analysis promises to improve citation analysis for research evaluation, knowledge network analysis, knowledge representation, and information retrieval. The present study showed the importance of filtering out nonessential citations before assigning weight in a weighted citation analysis, which may be a significant step forward to realizing these promises. Originality/value： Weighted citation analysis has long been proposed as a theoretical solution to the problem of citation analysis that treats all citations equally, and has attracted increasing research interest in recent years. The present study showed, for the first time, the importance of filtering out nonessential citations in weighted citation analysis, pointing research in this area in a new direction.
