Research characteristics and trends of power sector carbon emissions: a bibliometric analysis from various perspectives.

Power sector carbon emissions (PSCEs) have received an increasing attention due to their huge contribution to global greenhouse gas emissions. Herein, the research characteristics and trends of PSCEs are investigated based on bibliometric analysis. The basic growth trends, contributions of the most productive countries/territories, institutions, authors, journals, and subject categories are analyzed systematically. In addition, the major research fields and research trends are investigated by the keywords co-occurrence analysis and topic evolution. The result indicates that PSCEs research has developed rapidly in the past 20 years, and the proportion of research funding has increased from 0 at the beginning to 73% in the last 5 years. Especially, the number of scientific publications has shown an explosive growth after the signing of the Paris Agreement in 2016. The People's Republic of China (PR China), the USA, and England are the three most dynamic countries in the field of PSCEs research, with 64.8% of the total number of published papers. The most productive institutions are also from these countries. Based on keywords co-occurrence analysis, it is concluded that driving factors, prediction, impacts, and countermeasures of carbon emission are three major research fields. The result of thematic evolution indicates that the topics on energy transition, life cycle assessment, marginal abatement cost and energy policy have been the research hotspots in recent years. This study presents an worldwide overview of PSCEs research, thus helping the stakeholders to quickly grasp the research trends and conduct future work.

[Thoughts on post-marketing evaluation of classical Chinese patent medicines based on clinical value].

Classical Chinese patent medicines(CPMs) are a kind of modern preparation developed from the experience of compatibility and application about ancient prescriptions. Its rich history of human use and reliable clinical efficacy imply the unique theoretical essence and precious value of traditional Chinese medicine(TCM). With the development of evidence-based medicine and the improvement of medical policy, it is particularly urgent to evaluate the clinical values of post-marketing classical CPMs. In this paper, some problems on the clinical value evaluation of CPMs would be described, and it is considered that the simplified evaluation procedures can lead to the lack of evidence for evaluating clinical value of CPMs, causing the difficulty in evaluating the quality of CPM, lack of R&D motivation of enterprises, low content of science and technology, and poor international development. Based on this background, it points out that the clinical value evaluation is the core of the post-marketing evaluation of the classical CPMs, and the eva-luation should be based on the direction of literature research and the latest practice. We should adhere to the research mode of combination disease with syndrome, and select the appropriate type of trials, with clinical efficacy, health economic benefits and safety eva-luation as the main content of the studies, in order to refine the indications and standardize the clinical positioning. Clinical value eva-luation is the basis and main content of post-marketing comprehensive researches on classic and famous CPMs to clarify their clinical value, obtain the conditions for continued marketingand standardize their clinical application, so as to optimize the evidence and quality service of classic and famous CPMs and inherit the core value concept of Chinese medicine.

Understanding the funding characteristics of research impact: A proof-of-concept study linking REF 2014 impact case studies with Researchfish grant agreements.

BACKGROUND: All parts of the research community have an interest in understanding research impact whether that is around the pathways to impact, processes around impact, methods for measurement, describing impact and so on. This proof of concept study explored the relationship between research funding and research impact using the case studies submitted to the UK Research Excellence Framework (REF) exercise in 2014 as a proxy for impact. METHODS: The paper describes an approach to link the REF impact case studies with the underpinning research grants present in the Researchfish dataset, primarily using the publications captured in both datasets. Where possible the methodology utilised unique identifiers such as Digital Object Identifiers and PubMed ID's, and where this was not possible the funding information within each publication was used. RESULTS: Through this automated approach 21% of the non-redacted case studies could be linked to a specific research grant. Additional qualitative analysis was then done for unlinked REF impact case studies, which involved reading the document to identify additional information to make the linkage. This approach was taken on 100 REF impact case studies selected at random and resulted in only seven having no identifiable research grants funding associated. The linked research grants were analysed to identify characteristics that are more frequently associated with these grants, than non-linked ones. CONCLUSIONS: This analysis did point to some interesting observations such as the grant funding linked to REF impact case studies are more likely to be longer, higher financial value, have more publications and be more collaborative (amongst other characteristics). These findings should be used with caution at present and not be over interpreted, this is due to the sample size for this proof of concept study and some potential limitations on the data which were not addressed at this stage.
