The relationship between active coping and hope during the COVID-19 pandemic: The mediating role of meaning in life.

This study aims to examine the relationship between active coping and hope during the COVID-19 pandemic and investigate the underlying mechanism based on meaning making theory. We conducted a two-wave survey and recruited 521 Chinese adults (aged 18-65). Results show that all three active coping strategies (personal hygiene practice, support seeking, and positive reappraisal) at T1 was positively associated with T2 hope. Importantly, T2 meaning in life serves as a mediator between T1 active coping and T2 hope. Our findings suggest that active coping could be an effective approach to maintain mental health by making meaning and promoting hope.

[Simulation Analysis of the Impact of COVID-19 Pandemic Control on Air Quality in Henan Province based on Machine Learning Algorithm].

To reduce the risks of COVID-19 on society and the health of the general public, necessary prevention and control measures were implemented throughout China in 2020. Consequently, air quality was greatly improved due to lower emissions. However, the improvement of air quality could also be closely related to meteorological conditions. During quarantine (January 27 to February, 2020), reductions were observed in the concentration of all air pollutants in Henan Province (PM2.5, PM10, SO2, CO, and NO2 decreased by 36.89%, 34.18%, 19.43%, 29.85%, and 58.51%, respectively) relative to measurements taken from January 1 to 26, 2020. The only exception was for the concentration of O3, which increased by 69.64%. This study evaluates the importance of meteorological conditions in air pollution, through simulation with a long-and-short-term memory network (LSTM) and a machine learning algorithm. Results show that meteorological conditions play a crucial role in air pollutant formation. Given favorable meteorological factors, the concentrations of pollutants could be reduced by 15%-30%, while the reduction due to anthropogenic emission control ranges from 6%-40%. During the epidemic, meteorological conditions and human emissions accounted for 34.84% and 34.81% of the increase in O3 concentration, respectively. The results show that primary pollutant concentrations are more sensitive to the intensity of anthropogenic emissions. However, secondary pollutants are more dependent on meteorological factors. Furthermore, a nonlinear relationship has been identified between O3 concentration and to emission intensity. Further investigation into the causes of the rise in O3 concentration is necessary to gain a greater understanding and better control of particulate matter and O3 pollution.

Coping with coronavirus disease 2019: Relationships between coping strategies, benefit finding and well-being.

The coronavirus disease 2019 (COVID-19) pandemic has caused both physical and psychological changes in the general public. The current study aimed to examine the relationship between well-being and coping strategies in response to the pandemic. Furthermore, we aimed to investigate the mediational role of benefit finding. A total of 521 participants aged 18-65 years were recruited from 29 regions of mainland China. Situation-specific coping strategies, including support seeking, personal hygiene practice and social distancing, were measured at Time 1. Benefit finding and well-being were assessed 1 month later. A multilevel mediation model was conducted with region included in level 2 as cluster ID. Support seeking and personal hygiene practice were positive predictors of benefit finding, which further mediated their relationships with well-being, while social distancing negatively predicted well-being. These results highlight the relationships of support seeking, personal hygiene practice and benefit finding with well-being during the COVID-19 pandemic. Our findings indicate that besides adopting adaptive coping strategies to prevent infection by COVID-19, individuals should be encouraged to recognize benefits associated with the COVID-19 outbreak.
