Emerging research trends on biochar application in agriculture: A scientometric analysis

ABSTRACTThis work presents empirical evidence of the main challenges in managing/leading academic research groups on clean and green technologies in Brazilian universities. We also present evidence about the main barriers to the effective creation of innovation and technology transfer of these clean and green technologies. Empirical evidence come from PhD researchers/academics who lead/manage official research groups on clean (environmental, green) technologies. Results show the following: (a) The main challenges of managing research groups are the lack of an innovative culture, the lack of partnership with an industrial sector, and the necessity of keeping laboratories updated; (b) the main barriers to innovation and technology transfer are difficulties in not having enough researchers and staff members, assessments of academic performance that do not consider innovation, and an uncertain national legislation on clean technology. Based on these and others’ findings, we suggest that policymakers working on clean and green technologies pay attention to act and develop initiatives focusing on the following: providing direct financial support for laboratory improvement, linking academics and practitioners from the industrial sector, and providing training and development programs on clean and green technologies’ legislation and financial issues, such as the payoff of clean and green technologies and opportunities from green investors.

To study the funding and achievements in the field of organ transplantation support by the National Natural Science Foundation of China (NSFC). A search of NSFC database was made by using the key word "transplantation" and excluding "bone marrow transplantation" for the projects funded between 1988 and 2013. SCI indexed publications that marked with NSFC project number were collected by searching each grant number in the database of the Web of Science. Six hundreds fifty-five projects were identified and received about 220 million yuan in grant funding. These funded research projects were distributed among 25 provinces and autonomous regions, however, which were mainly in the developed coastal areas; of them, 43 (6.56%) projects were granted in xenotransplantation and 17 projects (2.60%) were funded in the field of traditional Chinese medicine-related organ transplantation; Transplantation on blood vessels, heart, kidney, liver, lung, small intestine, pancreatic, cornea, trachea, skin, etc. were primarily performed in research. Nine hundreds and sixty-one SCI-indexed publications were achieved. Magnitude and intensity of NSFC funding, output of SCI publications have been increasing, suggesting that NSFC positively promotes the development of organ transplantation. Although a great progress of transplantation has been made, basic and translational studies should be vigorously strengthened.

BackgroundModern neurosurgery is a relatively young discipline characterized by finesse and complexity. In recent years, neurosurgery in China has made continuous developments, with long-term progress and outstanding discoveries in many aspects of the field.ObjectiveThis scientometric investigation aimed to comprehensively provide insight into the development trends of neurosurgery in China, to demonstrate how the field has evolved.MethodsPubMed database was searched to retrieve relevant papers published between 1988 and 2018 from neurosurgery institutions in China. The database of the National Natural Science Foundation of China was also retrieved for funding information. Information (eg, year of publication, journal, institute of origin) and keywords were collected from each paper after removing duplicates and filtering unintentional words. Co-word analysis was performed on the papers’ keywords, and a time distribution matrix of coexisting keywords in a given paper (ie, termed co-words) was established. Co-words were clustered according to their growth rate within years and visually presented with a mountain plot and a heatmap. Trends and potential subspecialties were identified, and each topic, represented either by a co-word from publications or funding from the National Natural Science Foundation of China during the period from 2011 to 2018, was collected and analyzed.ResultsWithin 15,972 publications on neurosurgery from institutions in China, diagnostic image was found to coexist the most with other keywords. Cluster 0, represented by diagnostic image with retrospective study, contained emerging topics with great developmental potential and demonstrated high growth rates in recent years. This finding suggests that the topics represented in Cluster 0 may represent future areas of important neurosurgical research. We also found that the developmental trend of China’s neurosurgical research is highly correlated with National Natural Science Foundation of China funding acquisition.ConclusionsCo-word analysis and visualization results provided insight into the emerging research topics that are of vital importance, which can be used as a reference by neurosurgeons and researchers for future investigations. In this study, our analysis strategy based on co-word biclustering was able to clearly demonstrate current academic subject development; therefore, co-word biclustering is a reliable bibliometric analysis strategy.
