In the current teaching context, mathematics has become the most popular subject among all disciplines, and the establishment of mathematics teaching evaluation and feedback mechanisms is particularly important. The study constructs a feedback mechanism for mathematics teaching based on error analysis using the improved hierarchical analysis method and fuzzy comprehensive evaluation method. The mathematics teaching feedback mechanism and the traditional manual feedback mechanism are used to compare the performance of error analysis. Completely evaluating math teachers in Z-school using the math teaching evaluation index system. Compare the students’ math scores before and after the implementation of the math teaching feedback mechanism to explore the application effect of the feedback mechanism. The results show that the overall error of the math teaching feedback mechanism (1.12) is better than that of the traditional manual feedback mechanism (3.19), and the error fluctuation of the former is also smaller than that of the latter. The feedback results from the math teaching feedback mechanism are more accurate than the actual feedback results. The fuzzy comprehensive evaluation results of Teacher A are in the following order from highest to lowest: teaching method (93.069) > teaching content (92.531) > teaching objectives (91.645) > teaching effect (90.537) > teaching attitude (88.543). After the experiment of the math teaching feedback mechanism, the mean score of math achievement of the experimental group increased by 12 points. The control group decreased by 1.32 points, and the teaching feedback mechanism achieved significant results.

Employees' social media use in the workplace has become a common phenomenon. Thriving at work is a positive psychological state, and conventional wisdom and preliminary research on thriving at work indicate the benefits of thriving for both employees and organizations. However, few studies have linked social media use and employees' sense of thriving. Based on the socially embedded model of thriving at work, this paper explores the relationship between social media use and thriving at work, as well as the mediating role of knowledge sharing and the moderating role of locus of control. Mplus is used to analyze the data of 397 Chinese employees collected at two time points; the results show a significant positive impact of social‐related social media use on thriving at work. However, work‐related social media use was found to have no effect on thriving at work, though knowledge sharing mediates the relationship between social media use and thriving at work. In addition, locus of control moderates the relationship between work‐related social media use and thriving at work. [ABSTRACT FROM AUTHOR]

Background: Recent studies have shown that aspirin consumption may reduce the risk of hepatocellular carcinoma (HCC), but their correlation is still not fully understood. This meta-analysis aimed to investigate the correlation between aspirin consumption and HCC. Methods: A systematic literature search was conducted on PubMed, Scopus, Cochrane Library, EMBASE, and Web of Science databases. The search period was from the establishment of the database to July 1, 2022 with no language restrictions. Results: A total of 19 studies including three prospective studies and 16 retrospective ones with 2,217,712 patients were included. Compared with those who did not take aspirin, those who took aspirin had a 30% lower risk of HCC (hazard ratio [HR] = 0.70, 95% confidence interval [CI] 0.63–0.76, I2 = 84.7%, P < 0.001). Subgroup analysis showed that aspirin significantly reduced the risk of HCC by 19% in Asia (HR = 0.81, 95% CI 0.80–0.82, I2 = 85.2%, P < 0.001) and by 33% (HR = 0.67, 95% CI 0.61–0.73, I2 = 43.6%, P = 0.150) in Europe and the U.S with no significant difference. Moreover, in patients with HBV or HCV infection, aspirin reduced 19% and 24% of the risk of HCC, respectively. However, aspirin administration might increase risks of gastrointestinal bleeding in patients with chronic liver disease (HR = 1.14, 95% CI 0.99–1.31, I2 = 0.0%, P = 0.712). Sensitivity analysis showed no significant difference of results after excluding individual studies, suggesting that the results were robust. Conclusion: Aspirin may reduce the risk of HCC in both healthy population and patients with chronic liver disease. However, attention should be paid to adverse events such as gastrointestinal bleeding in patients with chronic liver disease. [ABSTRACT FROM AUTHOR]

The digital economy is a driving force for economic growth in various countries. When the digital economy is deeply integrated with Internet companies, it also brings about great challenges to corporate innovation. This paper used the DEA-Malmquist model to measure the efficiency of the science and technology investment of 30 Internet-listed companies in China from 2011 to 2019, constructing a long-distance function and displaying the dynamic changes in the comparative efficiency of time and space. This research evaluated the digital maturity and digital experience of Internet companies under the continuous investment of science and technology, concluding that the investment in science and technology under the digital economy can improve the innovation efficiency of China's Internet companies. Research shows that technology investment has a significant positive impact on the digitalization of Internet companies, but there is heterogeneity among different companies. Based on the theoretical research in this article and the empirical experience of in-depth digitalization, it also provides path suggestions for the in-depth development of digitalization of Internet companies. This research has important theoretical significance and practical value for further promoting the development of Internet companies and promoting the application of the digital economy.

To describe the ability of image fractional differential in texture detail enhancement and to study the lateral inhibition principle, multiform masks for digital image fractional differential and their operation rules are discussed. The theoretical basis of fractional differential in modulation and demodulation is also analyzed. Through the derivation on the relation between fractional differential and signal time-frequency analysis, we can acquire the separability of two-dimensional fractional differential under certain conditions. Mach's phenomenon generated in image texture detail is studied by us from two aspects: optic nerve model and signal processing, to propose novel masks. Then its operating rules for digital image processing based on fractional differential are proposed. The experiments show that our scheme can effectively reserve better information of edge texture detail during the denoising process, especially for weak texture and gray with little change. The total enhancing effect is obviously superior to integer order differential operator. [ABSTRACT FROM AUTHOR]

The COVID-19 epidemic has accelerated the digital economy's pervasiveness throughout the Chinese economy, leading to a sharp rise in demand for "contactless" services in the financial industry. We examine the digital transformation of the Chinese banking industry using the DEA–Malmquist index method, supplemented by a distance function and time to compare the dynamic changes of productivity. Our paper then conducts an empirical study on the digital transformation of Chinese commercial banks based on their improvements in efficiency. We analyze banks with superior efficiency in science and technology investment and evaluate their digital maturity and digital transformation experience. Results show that digitalization investment has contributed to substantial production efficiency improvement for commercial banks; however, heterogeneity exists across banks. We further advocate a path for banks' digital transformation based on theoretical research and empirical digital transformation experience in this area. [ABSTRACT FROM AUTHOR]
