In December 2019, COVID‐19 broke out in Wuhan, China, affecting the mental health and quality of life (QoL) of its inhabitants. This study aimed at investigating the factors associated with anxiety and QoL in the Wuhan populace during the COVID‐19 pandemic. An online questionnaire survey was carried out during July 6–10, 2020. The questionnaire collected information on demography, anxiety, QoL, and social‐environmental support. The main statistical methods included descriptive statistics, independent‐samples t‐test, one‐way analysis of variance, and multivariate regression analysis. In total, 226 participants were recruited. The findings showed that females, elderly, middle‐income, poor health status, shortage of medical supplies, and insufficient basic commodities were associated with anxiety significantly. Multiple regression analysis indicated that social‐environmental support was significantly related to anxiety. Higher social‐environmental support was significantly associated with a higher QoL. Our findings showed that the social‐environmental support may reduce anxiety and improve the QoL for those living in an area heavily affected by the pandemic.

There is an increasing recognition of the strong links between the gut microbiome and the brain, and there is persuasive evidence that the gut microbiome plays a role in a variety of physiological processes in the central nervous system. This review summarizes findings that gut microbial composition alterations are linked to hippocampal neurogenesis, as well as the possible mechanisms of action; the existing literature suggests that microbiota influence neurogenic processes, which can result in neurological disorders. We consider this evidence from the perspectives of neuroinflammation, microbial-derived metabolites, neurotrophins, and neurotransmitters. Based on the existing research, we propose that the administration of probiotics can normalize the gut microbiome. This could therefore also represent a promising treatment strategy to counteract neurological impairment.

We investigated how the transition to remote instruction amidst the COVID-19 pandemic affected students’ engagement, self-appraisals, and learning in advanced placement (AP) Statistics courses. Participants included 681 (Mage=16.7 years, SDage=.90; %female=55.4) students enrolled in the course during 2017-2018 (N=266), 2018-2019 (N=200), and the pandemic-affected 2019-2020 (N=215) year. Students enrolled during the pandemic-affected year reported a greater improvement in affective engagement but a decrease in cognitive engagement in the spring semester relative to a previous year. Females enrolled in the pandemic-affected year experienced a greater negative change in affective and behavioral engagement. Students enrolled during the pandemic-affected year reported a greater decrease in their anticipated AP exam scores and received lower scores on a practice exam aligned with the AP exam compared to a prior year. Though resilient in some respects, students’ self-appraisal and learning appeared negatively affected by pandemic circumstances.

The object of the study is to use the technology acceptance model to explore the willingness and pattern of usage of the consumers. 205 valid questionnaires were collected by using the Google online survey platform. Using IBM SPSS and AMOS Statistics 20.0 software, first background information was analyzed, then CFA was used to analyze the relationship between variables, and SEM was used to verify the rationality of the measurement model. The result discovered that there is a positive effect on perceived usefulness by perceived utility of usage by the users. There is a positive effect on usage intention by perceived utility. There is a positive effect on perceived curiosity by perceived utility. There is a positive effect on usage intention by perceived usefulness, and there is a positive effect on usage willingness by social support for the wearable device users. However, there is no positive effect on usage willingness by perceived curiosity. Conclusion. If the industry can provide consumers with a good experience, it will help enhance consumer attitudes, increase consumer willingness, and continue to enhance consumer curiosity. Simply satisfying consumers' curiosity cannot increase consumer willingness, but social support will affect consumers' willingness to use.
