The Current Situation, Hot Spots, and Suggestions on the Education Research of the “Four Histories” in Universities—Visualization Analysis Based on CiteSpace

Universities are an important support for cultivating qualified socialist builders and reliable successors. Carrying out “Four Histories” education in universities is of great significance in enhancing the political, ideological, and emotional identity of college students, and fully implementing the fundamental task of cultivating morality and cultivating talents. Using CiteSpace to visualize and analyze the current status and hotspots of the “Four Histories” education research in Chinese universities, and then construct a scientific knowledge graph. Research has found that the number of publications in this field has shown a gradually increasing trend over time; The cooperation between researchers and publishing institutions is loose, and a highly cohesive research group has not yet formed; The research topics mainly focus on universities, college students, ideological and political courses, the new era, value implications, and practical paths; There is relatively little research on the “Four Histories” education in vocational colleges; Scholars generally use theoretical research and rarely use empirical research. Promoting the education of “Four Histories” in universities should strengthen communication and cooperation among ideological and political workers in universities, and build a strong collaborative research community. Continuously adapting to changes in the international situation and meeting the growth needs of young college students.

Interfacial Chemistry of Thiophene As an Effective Film-Forming Additive on High Voltage Cathode Revealed By Operando Raman Spectroscopy

For decades intense research efforts have been aimed at increasing energy densities with new rechargeable lithium battery (RLB) designs to meet the anticipated increasing energy storage demands. These efforts have yielded much higher capacities with novel materials. However, the theoretical capacity of an RLB cell is seeded in the structure of the electrode, while its practical capacity, performance, cycle life, and safety are deep-rooted in the side reactions at the interphase between electrode and electrolyte (interphase is the phase at the electrode-electrolyte interface) 1,2.Interphases are essential for the operation of the cells and have been widely recognized as the "most important and the least understood" components of RLBs3. While their characteristics determine their performance, they are not part of the design of RLBs, but only form during the cell operation on the anodes and cathodes. They constitute passivation layers with mixed chemistries due to the electrolytes' electrochemical stability window (ESW) being smaller than the operating potential of RLBs. Although interphase formation is of functional importance, its formation imposes a heavy price on the cell's performance. Formation of the interphase consumes the electrolyte and active lithium stored in the cathode and causes a dramatic capacity loss, especially in the initial charge/discharge cycles. Also, the presence of the interphase introduces a high level of impedance to the cell, which interrupts the fast and constant flow of Li-ion between the anode and cathode. Last but not least, interphase is an active and complex medium that changes its chemical composition and transport properties during charge/discharge cycling and storing conditions. This results in a constant evolution of the interphase and capacity fading, which is more prominent in the high cell voltage applications. Achieving high cell voltage by increasing the cut-off voltage of LiNi x Co y Mn1−x−y O2 cathode (NMC) materials to 4.5 V is an effective way to enhance the energy density of RLBs4. However, a high level of parasitic and decomposition reactions result in severe capacity fading of the battery cell5.Many efforts have been made to improve the properties of the cathode interphase at high cut-off voltage by incorporating different strategies. The in vivo approach is one of the more successful attempts to design the cathode interphase by incorporating film-forming additives in electrolytes to suppress parasite reactions at the electrode-electrolyte interface6-8. In an ideal case, this film should be stable with cycling and have excellent conductivity for Li+ ions and low electronic conductivity9.Thiophene-based molecules are investigated as effective film-forming on NMC at high cut-off voltages of 4.5 V vs. Li/Li+. Electrochemical investigations show that thiophene oxidizes before carbonate-based electrolytes and forms a stable interphase with high conductivity for Li-ion. Also, the electrochemical performance of the cell is enhanced significantly in the presence of thiophene additive with capacity retention of 95% after 100 cycles (75% capacity retention of the benchmark system). To reveal the underlying mechanisms of the interphase formation and thiophene working principle on the surface of NMC cathode, we performed operando near-field Raman spectroscopy. The Raman and electrochemistry results indicate that a poly-thiophene film is formed that covers the surface of the cathode active materials uniformly, protecting further oxidation of the electrolyte and preventing transition metal dissolution and decomposition of the active cathode materials.

Reflections on the Use of SSCI Papers in Evaluating Social Sciences Research in Chinese Universities

Purpose: This review demonstrates how to position Social Sciences Citation Index (SSCI) papers reasonably in order to promote the reform and development of the system for evaluating social sciences research (E-SSR) in China. Design/Approach/Methods: This review examines the contributions made by SSCI papers after such papers became a tool in the E-SSR system in Chinese universities, and the resultant issues. This review analyzes documents pertaining to the E-SSR systems of more than 50 world-class universities with consideration to the inherent characteristics and historical mission of social sciences research in China. The findings serve as the basis from which to examine the future trends in the reform of the E-SSR system in Chinese universities. Findings: The application of SSCI papers as an E-SSR tool is not common in world-class universities. To date, the reform of the E-SSR system in Chinese universities has involved: (i) establishing a pluralistic evaluation mechanism, with equal importance placed on SSCI papers and other research achievements; (ii) emphasizing the need for caution in using SSCI papers as an E-SSR tool and instituting distinct treatments for various disciplines; (iii) reducing the importance attached to journal language and ranking, while emphasizing innovation quality and practical contributions; and (iv) establishing China’s E-SSR standards in order to achieve an equilibrium between internationalization and localization. Originality/Value: This review argues that although SSCI papers constitute an indicator of E-SSR system, their importance must not be overstated. The main purpose of the E-SSR system is to facilitate the development of social sciences with a style and characteristics unique to China.

An Empirical Study on the Efficiency of Basic Research in Chinese Universities Based on SE-DEA

Basic research is the basis and source of vitality for independent innovation, and an important way to realize the strategic goal of our national development. By analyzing the important components of input and output of basic research in universities, this paper establishes an evaluation index system, and then makes an empirical study on the efficiency of basic research of universities in 26 provinces and municipalities in China from 2009 to 2016 by using super-efficiency DEA method. The results show: (1) The efficiency of basic research in Chinese universities needs to be improved in general, but in recent years it has been rising steadily with a good development trend. (2) There are obvious differences in the efficiency of basic research among provinces and cities in China, and there are serious imbalances in the development of basic research among different regions as well

A Rough Hybrid Multicriteria Decision-Making Model for Improving the Quality of a Research Information System

Improving the quality of research information systems is an important goal in the process of improving the performance of research management in Chinese universities. Since the evaluation of information system (IS) quality is a multicriteria decision problem, it is critical to identify the interrelationships among the dimensions and criteria, and decide on the important criteria for proposed improvement strategies. This paper suggests a hybrid multicriteria decision-making (MCDM) model for improving the quality of a research information system. First, a rough method combined with the decision-making trial and evaluation laboratory and analytical network process (rough DANP) model is used to improve the objectivity of expert judgements. Additionally, the rough DANP can be used to construct an influential network relationship map (INRM) between research information system components to derive the criterion weights. The complex proportional assessment of alternatives with rough numbers (COPRAS-R) is applied to evaluate the performance of the research information system. A Chinese university research information system is chosen to illustrate the usefulness of the proposed model. The results show that efficiency, effectiveness, and user frequency have the highest priorities for improvement. Selected management implications based on the actual case study are supplied.

The Wing Pavilion:A Participatory Action Approach to Bamboo Architectural Research in Chinese Universities

The application of bamboo construction techniques in Chinese architecture remains behind its potential. Chinese universities began conducting participatory action research on bamboo as a building material. Students from the Huazhong University of Science and Technology designed the wing pavilion: a temporary bamboo structure built in six days inside the Nan Sha Bird Eco-Park, Guangzhou. The process combined handcraft and digital techniques within five steps: pre-design, formulation, successive answers, project, and conclusion of the theory. Eight bamboo arches interconnected to create a six-meter span roof. Each arch was pre-fabricated with two layers of split bamboo and one slender bamboo culm as reinforcement. The cartesian plane technique was utilised to overcome the indeterminacy of bamboo. Details could be fuller, and the roof lacked enough strength. More important than a perfect result, the principles of bamboo architecture transferred to students, and a range of scales can replicate the methodology. The technical solution reflected a Western functionality with an Asian essence. Many of the now underprivileged people will benefit from it since bamboo is abundant in China.

04/01189 Hydrogen bonds in coal. The influence of coal rank and the recognition of a new hydrogen bond in coal: Li, D.-T. et al. Chemical Research in Chinese Universities, 2003, 19, (1), 70–75

By means of in-situ diffuse reflectance FTIR, the IR spectra of 6 coals with different ranks were obtained from room temperature to 230 ℃. A new curve fitting method was used to recognize the different hydrogen bonds in the coals, and the influence of coal ranks on the distribution of hydrogen bonds(HBs) in the coals and their thermal stability were discussed. The results show that there is another new HB(around 2514 cm-1) between the -SH in mercaptans or thiophenols and the nitrogen in the pyridine-like compounds in the coals, and the evidence for that was provided. The controversial band of the HB between hydroxyl and the nitrogen of the pyridine-like compounds was determined in the range of 3028-2984 cm-1, and the result is consistent with but more specific than that of Painter et al.. It was found that the stability of different HBs in the coals is influenced by both coal rank and temperature. For some HBs, the higher the coal rank, the higher the stability of them. Within the temperature range of our research, the stability of the HB between the hydroxyl and the π bond increases to some extent for some coals at temperatures higher than 110 or 140 ℃.
