Corporate ESG and resilience of stock prices in the context of the COVID-19 pandemic in China

The COVID-19 pandemic has had a significant impact on both the financial market and the real economy, leading to widespread concern about the relationship between environmental, social, and governance (ESG) responsibilities and shareholders' wealth. This paper examines the relationship between ESG responsibility and stock returns in the context of the COVID-19 pandemic and investigates the impact of ESG responsibility on stock price resilience. The results indicate that corporate ESG scores have positive impacts on stock returns during and after the COVID-19 crisis, with the positive impacts of ESG being more significant in the post-crisis period. Among the different ESG dimensions, environmental responsibility (ESG_E) has a more significant impact on stock returns, while social responsibility (ESG_S) and governance responsibility (ESG_G) have mixed impacts during the crisis. Furthermore, during and after the outbreak of COVID-19, the positive impacts of ESG are more pronounced among firms located in low-trust regions and firms with lower analyst coverage. Additionally, the study finds that corporate ESG responsibility help restore the resilience of stock prices during the crisis, with better ESG performance leading to stronger stock price resilience. Overall, the results strongly support the conclusion that ESG has acted as an "equity vaccine” during the COVID-19 pandemic.

Worker Characteristics and Measures Associated With Patient and Visitor Violence in the COVID-19 Pandemic: A Multilevel Regression Analysis From China.

Objective: To analyze the patient and visitor workplace violence (PVV) toward health workers (HWs) and identify correlations between worker characteristics, measures against violence and exposure to PVV in COVID-19 pandemic. Methods: A cross-sectional survey utilizing the international questionnaires in six public tertiary hospitals from Beijing in 2020 was conducted, and valid data from 754 respondents were collected. Multilevel logistic regression models were used to determine the association between independents and exposure to PVV. Results: During COVID-19 pandemic and regular epidemic prevention and control, doctors were 5.3 times (95% CI = 1.59~17.90) more likely to suffer from physical PVV than nurses. HWs most frequently work with infants were 7.2 times (95% CI = 2.24~23.19) more likely to suffer from psychological PVV. More than four-fifth of HWs reported that their workplace had implemented security measures in 2020, and the cross-level interactions between the security measures and profession variable indicates that doctors in the workplace without security measures were 11.3 times (95% CI = 1.09~116.39) more likely to suffer from physical PVV compared to nurses in the workplace with security measures. Conclusion: Doctors have higher risk of physical PVV in COVID-19 containment, and the security measures are very important and effective to fight against the physical PVV. Comprehensive measures should be implemented to mitigate hazards and protect the health, safety, and well-being of health workers.

Contribution of traditional Chinese medicine combined with conventional western medicine treatment for the novel coronavirus disease (COVID-19), current evidence with systematic review and meta-analysis.

This study provides current evidence for efficacy and safety of treating COVID-19 with combined traditional Chinese medicine (TCM) and conventional western medicine (CWM). Six databases were searched from January 1 to December 31, 2020. Randomized controlled trials (RCTs), case-control studies (CCTs), and cohort studies on TCM or TCM combined with CWM treatment for COVID-19 were included. The quality of included RCTs was assessed by Cochrane risk of bias tool, and the Newcastle-Ottawa Scale (NOS) was used to assess the quality of cohort studies and CCTs. Review Manager 5.4 software was used to perform meta-analysis. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. A total of 35 studies (3,808 patients) composing 19 RCTs and 16 observational studies were included. The results of meta-analysis revealed that comparing with CWM alone, integrated TCM and CWM had significant improvement in total effective rate, improvement rate of chest CT, the rate of disease progression, as well as improvement of fever, fatigue and cough. The overall quality of evidence was very low to moderate. In conclusion, TCM combined with CWM was a potential treatment option for increasing clinical effective rate, improving the clinical symptoms, and preventing disease progression in COVID-19 patients. High-quality clinical trials are required in the further.
