Sense of gain is a comprehensive response of people’s subjective cognition and emotional experience to the process and results of satisfying their needs in social reform and development. It has become a new index reflecting the sharing of social development achievements and the improvement of people’s quality of life. This paper, based on the CASS-Matview Sense of Gain Survey 2019, analyzes its current situation and demographic differences, and explores the different characteristics in terms of different social classes. The results show that the public has a good overall sense of gain, with relatively high scores in the content, access and sharing, and relatively low scores in environment and experience. Objective social class indicators such as education level, income, occupation and housing situation have different effects on the sense of gain. With the demographic variables and the objective social class index controlled, the subjective social class still has a certain predictive effect, falling into a pattern of high at both ends and low in the middle. In view of this, some suggestions are put forward with an aim to provide a reference for making policies of social governance.

This paper, on the basis of previous studies, employs the data of CGSS (2010-2015) to analyze the impact of social economic status and subjective social class on one’s well-being. The study focuses on a comparison of the two indicators, and a longitudinal comparison through continuous data is added for an in-depth insight. The results tell that both indicators have an impact on individual’s well-being; the objective economic status index decreases slightly and changes slightly year by year after adding the subjective social class variables. In addition to current subjective social class, social class change in the past and the expected change in the future also weigh a lot, but the impact of the latter in 2015 is significantly lower than that in 2012.

This paper, analyzes the current perception of social justice in China from three aspects: rights justice, opportunity justice, and institution justice, and explores the impact of socioeconomic status and social comparison on such perception. The data is collected from 22,669 residents by employing CASS-INTELLVISION Social Mentality Survey (2017). The results show that their perception of social justice is generally low, and the justice of opportunity is the most highly questioned. The influencing factors mainly conform to the “local comparison theory” instead of the “structural determinism”. The subjective social class can enhance the sense of social justice, and positive social comparison and reasonable cognition of comparison results can improve social equity. The relationship between objective socio-economic status and social justice depends on the results of social comparison. When one’s social comparison is inferior to that of others, there lies a negative correlation between objective socio-economic status and social justice.

The fight against the Covid-19, globally a complicated war that seems to never end, also a torture of human civilization has plunged us into a reflection on the goal of “suspending classes without suspending learning”, and on two major challenges which decide the future of education of post the Covid-19. An in-depth insight of these issues and their solutions mainly rest on an analysis of different responses and choices in face of disease and health, life and death from three perspectives namely experience, science and philosophy. Pedagogy should give answers to three essential questions:“what to learn, how to learn and how to organize?” To be more specific, the content, structure, boundary and methodology of these three questions should be responded. To keep a health both physically and mentally, i.e. returning to normal, is a wise choice, a goal that we should pursue and an orientation of post the Covid-19. That is to say, we should cultivate students’ independence, team spirit and research-oriented learning ability within “the Three Worlds” in the collaborative innovation of school, family and community education. Only by employing such a practice can the education return to the normal track. We should build “education engineering” that well integrates the related disciplines within and without in practice. Such an approach meets the needs of the time on the one hand and will lead education into a new and good ecology on the other.

Online teaching has been widely employed, over the Covid-19, in colleges and universities across China. In view of this, based on the constructivism teaching theory and 4111 network questionnaires and interviews, the results the online teaching produced and reasons behind are analyzed both empirically and theoretically. The research shows that: 85.36% of the students are basically satisfied or satisfied with online teaching; there have been, however, some problems such as too many platforms to choose and lack of some function that we need, single teaching method, low interactive quality, and insufficient evaluation feedback. The reasons rest on insufficiency of constructing technology platform, unsmoothness of identifying teaching subject and content, miss of building online teaching situation, and poor interaction between teachers and students. Accordingly, we should strengthen technology empowerment, improve teachers’ information literacy, build a two-way linkage teaching mechanism, and promote the “double-line” integration, thus building a new normal of education and teaching.

The goal of “suspending classes without suspending learning” over the Covid-19, no matter we like it or not, has enhanced teachers’ online teaching quality and promoted a rapid development of online teaching and research. This paper first summarizes the connotation, characteristics and trends of online teaching and research, and then analyzes its characteristics in primary and secondary schools over the Covid-19, including the large-scale participation, intelligent technology support, online problems-the focuses, improvement of online teaching literacy-the objects, and accurate data for a good evaluation. Some followed-up suggestions are put forward accordingly, to enhance the normal awareness, to finish a good top-level design, to promote an effective integration of teaching and research resources, to carry out targeted assistance, and to follow a trend of online and offline integration.

As data is becoming a key force to promote teaching innovation, smart classroom provides convenient conditions for collecting teaching data in full dimension and in whole process. Even so there have been some practical problems in smart classroom teaching, such as unclear thinking in data application, and difficulty in exerting date value. To cope with that, the application should be based on the basic concept that “data can produce value only if in application, and date value bears a feature of attenuation”, and the mode, “goal-oriented” and “data oriented”, should be adopted. In terms of its typical scenario, careful lesson preparation, fine guidance, accurate evaluation, lean guidance, and efficient teaching and research are available. In terms of its characteristic, full dimension and full process, instant feedback, focus on students’ learning engagement are there. It gets involved in four key strategies 1) attaching great importance to multi-modal data acquisition and analysis so as to make the data application scientific; 2) casting great attention to the real-time feedback so as to enhance its timeliness; 3) setting a high value on students’ learning input so as to improve the diversity; 4) great emphasis is placed on the privacy protection of data so as to promote the security. Only in this way can the data application value of smart classroom be enhanced and the innovation and reform of data-driven teaching be promoted.

Behavior and process of learning affect its results. Learning behavior, according to an view of educational circles, is often conditioned by some external factors. That is why a “new normal” comes out when such factors have changed and such a change tends to be stable. For an adaptation, it is necessary to reconstruct a new learning ecology in which the digital existence corresponding to the digital age has changed the modern learning relationship and hybrid learning will become the basic feature of this ecological environment. Therefore, a new learning space should be built up accordingly. Such a space should be adaptive, i.e. it provides learners with not only adaptive learning support that meets their needs, but also an improvement of the adaptive level of the learning space after heavy use. The adaptability of learning space lies not in a pursuit of “individual adaptation”, but in that of a “class adaptation”. In practice, we need to fully respect the nonlinear structure of learning, cast attention to its attribute of whole space, and constantly optimize its degree and level.

Teaching and research community serves as an important means to improve teachers’ education and teaching ability, realize an integration of research and training, and promote the reform of school education and teaching. A study of the evolution of community, and of the implication of teaching and research community helps understand its research content, construction forms and functional orientation. That development for teachers in open university is blocked by many obstacles: the contradiction between vigorous development demand and limited supply, between continuous demand and intermittent supply, between diversified development demand and single supply mode, and between job burnout and personal promotion. To cope with that, some strategies are put forward as follows: 1) to build, with project and platform as the supporters, the consciousness and atmosphere of collaborative teaching and research; 2) to convert research results in time for promoting teaching and research; 3) to lay down flexible management rules for enhancing the optimization and improvement of the teaching and research system; 4) to innovate service supply of teaching and research for enhancing gradually teachers’ sense of research gain.

The traditional VAR model limits the variables to the same frequency, which destroys integrity of the original data, thus affecting performance of the model. In this study, MF-BVRA model, which well integrates quarterly and monthly variables, is introduced. The recursive samples of GDP, PPI, CPI and PMI are divided into three of different quarterly information groups. The performance of MF-BVAR is compared with that of MIDAS and co-frequency model. The transmission mechanism among variables is analyzed by mixing Granger Causal Relation Test, impulse response analysis and variance decomposition analysis. The empirical results show that: 1) compared with QF-BVAR, MF-BVAR’s real-time prediction errors in PPI, CPI, PMI and GDP are about 70%, 80%, 75% and 20% lower respectively; 2) real-time and short-term prediction performance of MIDAS and MF-BVAR, quantitative and statistical tests tell, are significantly better than that of QF-BVAR, and the latter does better in real-time forecasting, while MIDAS is good for short-term forecasting; the more monthly information is fully used, the smaller the prediction error will be, the recursive samples tell; (3) there is a bidirectional causal relationship between GDP and CPI, PPI and PMI, CPI and PMI, and the conduction time is different; while the forward conduction duration of PMI and GDP, PPI and GDP, PPI and CPI are all three periods, and the reverse conduction path is blocked without an asymmetry.

Under the impact of the Covid-19, the global supply chain’s having been shrinking has rendered international regional economic cooperation more prominent. “the Belt and Road Initiative”, a platform promoting international cooperation and its mechanism construction, has drawn more attention. This paper talks the rich contents of the initiative, and its positive role by elaborating China-Uzbekistan economic cooperation under the framework. The paper also points out the main problems and challenges that Uzbekistan encounters in economic development. Opportunities, directions, and policy suggestions for the country’s future reform and development are puts forward. The paper, based on the study of this typical case, in conclusion, gives some enlightenment on how to strengthen the mechanism construction under the framework: great emphasis should be placed on the positive role of the initiative; key cooperative areas should be well selected; key areas of cooperation should be given more attention; measures should be taken in case of cooperation risks, etc.

It has been the main approach and token of new urbanization for farmers to flow into cities and towns after their returning the farmland. Their withdraw, however, depends on many factors. To this end, this paper, based on the survey data of 580 households, with adopting the Logit model, empirically tests the impact of pension on such intention. The results show 1) farmers’ participation in urban employees’ endowment insurance significantly enhances their willingness; 2) the influence curve of pension level shows an inverted U-shape. In view of this, suggestions are put forward as follows 1) rural residents stably employed in the urban areas should be covered by the old-age insurance system for urban workers; 2) pension for urban and rural residents should be appropriately improved and the compensation for farmers should be raised; 3) farmers’ rights and interests should be guaranteed.
