摘要：
Property enterprise has contributed significantly to the prevention and control of COVID-19, and its functions received positive feedback from the urban residents via a survey. Detailed data on confirmed COVID-19 cases in 446 communities in Wuhan were collected and the property fee of each community was used to assess the quality of the property services provided. Both binary logit and ordered logit models were used to measure the impact of property fees on the pandemic prevention and control efficiency of each community. The results showed that a higher property fee corresponded to a better property service and a higher probability that the residential community would be free of COVID-19. Furthermore, where property fees were higher, pandemic prevention and control efficiency increased and the community achieved a lower pandemic risk level. In conclusion, the promotion of high-quality property services is conducive to community disease prevention and control in the case of a pandemic.

摘要：
INTRODUCTION: Adolescence is a sensitive transitional period accompanied by great physical, mental, and behavioral changes. Therefore, maintaining physical and mental health is crucial to the growth and development of adolescents. As one of the important indicators of mental health, the influencing factors of life satisfaction have been widely concerned by scholars. In recent years, with the rapid development of Internet technology, mobile social media has penetrated into all aspects of adolescents' life, which has a subtle impact on their physical and mental health. Existing studies have indicated that mobile social media use can affect adolescents' life satisfaction. However, little is known about the mediating and moderating mechanisms linking this association. This study developed a moderated mediation model to examine the mediating role of meaning in life and the moderating role of childhood psychological maltreatment. METHODS: A total of 1,198 adolescents across four provinces and municipalities of China completed questionnaires on mobile social media use, life satisfaction, meaning in life, and childhood psychological maltreatment. RESULTS: After controlling for gender and age, the results demonstrated that mobile social media use was positively associated with life satisfaction and meaning in life among adolescents. Moreover, meaning in life fully mediated the association between mobile social media use and life satisfaction. Finally, the association between mobile social media use and life satisfaction, as well as that between mobile social media use and meaning in life, was moderated by childhood psychological maltreatment. Specifically, these associations are stronger for adolescents with high levels of psychological maltreatment. DISCUSSION: These findings shed light on the important mechanism underlying mobile social media use's effects on adolescents' life satisfaction, which is helpful to formulate targeted measures for improving adolescents' life satisfaction.
摘要：
Epidemic shocks have brought the issue of household economic vulnerability to the fore. Furthermore, an urgent need to establish a long-term mechanism to particularly help low-income groups cope with risk shocks, and minimum wage policies should be able to play an important role. Therefore, based on CHFS panel tracking data in 2015, 2017, and 2019, the impact of the minimum wage increase on household economic vulnerability and its mechanism of action is empirically tested. We found that for every 10% increase in the minimum wage, the probability of economic vulnerability occurring in the household economy decreases by 2.81 percentage points because the minimum wage increase raises the household income level of low-income groups, improves the health status of household members, and increase their commercial health insurance, emergency savings and financial capital stock. This impact is more significant for rural households, households in areas with high marketization levels, better rule of law levels and with low education levels. The article's research helps to comprehensively analyse the welfare effects of minimum wage policies and expand the policy options for helping low-income groups cope with risk shocks.(c) 2023 Economic Society of Australia, Queensland.

摘要：
This paper studies the transmission of oil price uncertainty (OPU) shock to real economic activities by focusing on the role of financial condition. We find that financial stress is an important link in the propagation of OPU shock based on China’s macro- and firm-level data. We document significant decrease in real economic activities as oil price uncertainty increases by using SVAR, and further suggest that the contractionary effect of oil price uncertainty is more pronounced under high financial stress. Firm-level evidence consistently shows that heightened financial distress cost – resulted from oil price uncertainty – suppresses investments. OPU shock may cause financial distress through mechanisms of credit crunch, firm volatility and exchange rate uncertainty.

摘要：
Aiming at large-scale decision-makers (DMs) and the loss of decision sample information in large-scale group decision-making (LSGDM), a novel statistical estimation method incorporating the reliability and entropy of linguistic distribution assessment is proposed. First, classify the large-scale DMs into several subgroups according to their prior decision efficiency distribution. After clustering, collect the five-number summary of the incomplete decision sample information provided by the DMs in the subgroups. Second, estimate the mean, standard deviation, skewness and kurtosis of the decision sample via the Cornish–Fisher expansion. Then utilize the Bayes estimation to address the reliability of the subgroups, thereby obtaining the confidence interval, which is used to develop the interval linguistic distribution preference relation (ILDPR) for the subgroups. Moreover, combine the reliability and the entropy measure constructed by the above four estimators to determine subgroup weights. Furthermore, present the expectation and variance of the ILDPR to sort the alternatives. Finally, demonstrate the feasibility and validity of the proposed LSGDM method based on a case and a comparison.
