Competitive Intelligence： Bibliometric Research on Early Signals

Considering the importance of the anticipated intelligence issue on the current scenario, this article aims at understanding the scientific production about the subject, contributing to future researchers with greater academic knowledge about the productivity in the area. Therefore, a bibliometric research was carried out on weak signals and correlated matters between 1980 and 2010 and was supported by the literature review about the subject. The suggested analysis contributes to greater academic knowledge on productivity in the field, providing a broad perspective for future researchers who catch sight of this subject as a potential for further studies.

Global research trends in the field of liver cirrhosis from 2011 to 2020: A visualised and bibliometric study

BACKGROUND Liver cirrhosis is the leading cause of liver-related mortality worldwide. It is currently a global health challenge.AIM This research intended to explore and analyse research trends and frontiers in this field during the last 10 years, providing new inspiration for clinical decisionmaking and scientific research.METHODS Publications on hepatic cirrhosis research were retrieved from the Web of Science Core Collection on April 4, 2021. Bibliometric visualisation was conducted through VOSviewer and CiteSpace.RESULTS The analytic research was based on original articles and reviews. A total of 7775records of hepatic cirrhosis published from 2011 to 2020 were retrieved. In the past ten years, the number of related annual publications has increased significantly, especially in the United States and China. All publications were distributed among 109 countries. The United States contributed the most(21.95%)and was consistently the leading driving force, with a solid academic reputation in this area. The University of Barcelona distributed the most related articles(177articles) and was cited the most frequently. The Journal of Hepatology ranked third in the top 10journals, which has the highest impact factor(impact factor 2019 = 20.582). Jasmohan S. Bajaj was the most productive author(72 articles). Burst keywords(e.g., sofosbuvir, burden, care, sarcopenia,chronic liver failure, human gut microbiome, and nonalcoholic fatty liver disease) and a succession of reference citation bursts have provided clues about research frontiers in recent years.CONCLUSION This study identified developing trends in the evolution of liver cirrhosis to provide new inspiration for researchers.

A bibliometric review of nitrogen research in eutrophic lakes and reservoirs

The global application of nitrogen is far greater than phosphorus, and it is widely involved in the eutrophication of lakes and reservoirs. We used a bibliometric method to quantitatively and qualitatively evaluate nitrogen research in eutrophic lakes and reservoirs to reveal research developments, current research hotspots, and emerging trends in this area. A total of 2695 articles in the past 25 years from the online database of the Scientific Citation Index Expended（SCI-Expanded） were analyzed. Articles in this area increased exponentially from 1991 to 2015.Although the USA was the most productive country over the past 25 years, China achieved the top position in terms of yearly publications after 2010. The most active keywords related to nitrogen in the past 25 years included phosphorus, nutrients, sediment, chlorophyll-a, carbon,phytoplankton, cyanobacteria, water quality, modeling, and stable isotopes, based on analysis within 5-year intervals from 1991 to 2015 as well as the entire past 25 years. In addition, researchers have drawn increasing attention to denitrification, climate change, and internal loading. Future trends in this area should focus on：（1） nutrient amounts, ratios, and major nitrogen sources leading to eutrophication;（2） nitrogen transformation and the bioavailability of different nitrogen forms;（3）nitrogen budget, mass balance model, control, and management;（4） ecosystem responses to nitrogen enrichment and reduction, as well as the relationships between these responses; and（5）interactions between nitrogen and other stressors（e.g., light intensity, carbon, phosphorus, toxic contaminants, climate change, and hydrological variations） in terms of eutrophication.

Information visualization analysis on Advances in Psychological Science:1983-2014

Objective： To describe the revolution and research status of Advances in Psychological Science. Methods： A total of 3060 articles published in Advances in Psychological Science from 1983 to 2014 were analyzed with the information visualization method using Citespace software from the aspects of pub- lications, cited frequency and downloads, funding, organizations, authors and keywords. Results： The results showed that the amount of literature published annually had an upward tendency, and 49.4% of the papers were supported by national or provincial projects. Institutions such as the Chinese Academy of Sciences （CAS） and the normal universities were rated in the forefront of the sci- entific research output. Xiting Huang, Hong Li and Yuejia Luo were at the top of the list of prolific authors. Conclusions： A new pattern of cooperative development of the theory and application in the field of psychological research is forming.
