Abstract： [Purpose/significance] For the identification of important nodes in complex networks, the paper designs a node centrality algorithm, which plays an important role in infectious disease prevention and control, public opinion monitoring, product marketing, talent discovery and so on. [Method/process] This paper proposed a new node centrality algorithm, the HHa node centrality algorithm, taking both the number of the node's high influence neighbors and their total influence into consideration. On the real network and artificial network, the Susceptible-Infected-Recovered (SIR) model was used to simulate the information dissemination process, and the monotonic function M and Kendall correlation coefficient were used as evaluation indicators to verify the effectiveness, accuracy and stability of the HHa centrality algorithm. [Result/conclusion] The experimental results show that, compared with the 7 classic centrality algorithms, the HHa centrality algorithm ranks 2nd with a monotonic result of 0.999, and the Kendall coefficient is 0.845, which is higher than other algorithms' accuracy about 0.15, ranking 1st and performing robustly. It is feasible to use HHa centrality algorithm to identify important nodes in the network.

Abstract： Basic research is the source of original innovation. Strengthening basic research, looking forward to the future scientific development direction, and seizing the commanding heights of future development are the new requirements for the academic leadership of the Academic Divisions of the Chinese Academy of Sciences (CASAD) in the new era. The Discipline Development Strategy Research Program (DDSRP) of CASAD aims to explore the internal development rules of each discipline, to look forward to the medium and long-term development trends of various disciplines, to grasp the development direction of emerging and interdisciplinary subjects, to clarify the frontiers of science and major scientific issues, and to guide the development of the related disciplines in China. This paper introduces the basic situation of the research work of DDSRP of CASAD, and analyzes the influence and impact of DDSRP based on literature research and questionnaire survey. Research results show that DDSRP has produced sound social impacts, policy influences and academic influences on consolidating the foundation of disciplines, improving the layout

Abstract： [Purposes] To explore the role and function of volunteers in the academic quality control of preprint platforms, and to provide a reference for the construction of preprint platforms in China. [Methods] Using a web-based survey and case study method, we investigated and summarized the current situation of volunteer mechanism development in more than ten internationally renowned preprint platforms. Based on the research results, the most representative arXiv and RePEc were selected as research objects, and the impact of the infrastructure and organizational functions of the volunteer mechanism on the academic quality control of preprint platforms was analyzed in depth. [Findings] The maturity of the volunteer mechanism of the international preprint platform varies greatly; The current volunteer mechanism of arXiv and RePEc has the structure of volunteer work mechanism with clear rights and responsibilities, and the diversified academic quality control function of volunteers' deep participation, but the types of roles played by volunteers on the two platforms are different. [Conclusions] Volunteers are an important part of the quality control system of preprint platforms. China's preprint platform should widely recruit volunteers, gradually establish and improve the volunteer mechanism; optimize the volunteer mechanism structure and clarify the volunteer work functions; draw on international experience to enrich the academic quality control functions under the participation of volunteers.

Abstract：
At present, scientific data management is being highly concerned and closely studied by scientific research institutions all over the world. Comparing and analyzing the similarities and differences between international and domestic scientific data policy research is conducive to the development of this field. This paper selects the papers related to scientific data policy as the research object, uses the methods of literature metrology and content analysis to analyze the development characteristics and evolution trend of international and domestic research in this field, and reveals the research hot spots. The results show that both international and domestic scientific data policy research are in the stage of exploration and development, and the amount of research literature fluctuates and increases. The research direction is dominated by information science and library science, and some research belongs to interdisciplinary achievements. International research pays more attention to scientific research data sharing, while domestic research focuses on scientific data policy, data management and the research relationship between scientific research data.

Abstract： Purpose/Significance The paper proposes a method for the selection of representative papers, which provides support for the selection and evaluation of representative works. Method/Process Considering the innovation and influence of the papers comprehensively, the paper designs a representative index, and takes the papers with the highest representative index as the representative papers of scholars. Taking an outstanding scientist as an example, the paper selects his representative papers, and uses the main path analysis method to test the innovation and influence of the selected representative papers. Result/Conclusion The empirical results show that the representative index can effectively select the representative papers of scholars, and it is feasible to use the method to select the representative papers.
