IntroductionDuring the COVID-19 outbreak, many citizens were asked to stay at home in self-quarantine, which can pose a significant challenge with respect to remaining physically active and maintaining mental health. This study aimed to evaluate the prevalence of inadequate physical activity, anxiety, and depression and to explore the relationship of physical activity with anxiety and depression symptoms among Chinese college students during quarantine.MethodUsing a web-based cross-sectional survey, we collected data from 1,396 Chinese college students. Anxiety and depression were assessed with the Self-Rating Anxiety Scale and the Self-Rating Depression Scale, respectively. The data on physical activity were collected by types of physical activity and the International Physical Activity Questionnaire.ResultsDuring the COVID-19 outbreak, about 52.3% of Chinese college students had inadequate physical activity. The rates of anxiety and depression symptoms were 31.0 and 41.8%, respectively. A high level of physical activity was significantly closely associated with low anxiety, while a moderate, or high level of physical activity was significantly closely associated with reduced depression after adjusting confounding demographic factors. Moreover, specific types of physical activity, such as stretching and resistance training, were negatively correlated with both anxiety and depression; doing household chores was negatively correlated with depression.ConclusionOur findings highlight specific levels and types of home-based physical activities that need to be taken into consideration to protect the mental health of college students during the COVID-19 epidemic.

This study investigates how corporate corruption management and business ethics influence ESG reporting transparency in Asian firms, utilizing a dataset comprising 663 firms across 11 countries from 2013 to 2023. Addressing a significant research gap in emerging markets, it further examines whether business ethics moderates the relationship between corruption management and ESG disclosures. Grounded in agency, legitimacy, and signaling theories, the findings yield three core insights: (1) robust anti-corruption practices are positively linked to ESG transparency; (2) firms with strong ethical orientations exhibit higher ESG disclosure levels; and (3) business ethics strengthens the positive association between corruption management and ESG transparency. Methodologically, the study adopts the difference generalized method of moments (DGMM) to address endogeneity concerns, employs alternative ESG proxies, and controls for sectoral heterogeneity, regulatory differences, and the quasi-natural shock of COVID-19. The results offer robust empirical support and yield practical insights for enhancing corporate transparency and sustainability across Asia's heterogeneous institutional landscapes.

Zhang Xuecheng made a systematic evaluation on Dai Zhen's scholarship in the 54th and 55th years of Emperor Qianlong since he had set up his own academic system at that time. There were two kinds of reasons for his evaluation: on one hand, to criticize the tendencies of scholars at that time; on the other hand, to set up his own academic system and to advocate his academic ideas.
