The association between changes in public sentiment induced by COVID-19 and green consumption behavior has not been studied deeply. This study proposes that the awe induced by the COVID-19 pandemic can have both negative and positive aspects, aiming to psychologically reveal why the pandemic is affecting green consumer behavior and explore potential pathways for differentiation. Research data were derived from Wuhan, China, and analyzed using experimental method. This study finds that awe of COVID-19 positively affects green consumption behavior. Specifically, due to fear, anxiety, and powerlessness, individuals with negative awe of COVID-19 instinctively need to respond to risk and pay more attention to their own safety and interests, so as to promote green consumption. However, positive awe of COVID-19 involves higher levels of cognition, such as admiration, inspiration, and optimism. It inspires a commitment to prioritize nature and social groups, and promotes green consumption behavior. As conclusions, different types of awe can be induced from public health emergencies like COVID-19 and have their own specific paths to effect green consumption behavior. These findings could help governments and marketers build future policies and strategies to reasonably guide public sentiment in order to better promote green consumption in this epidemic.

It is significant for people with diabetes to know their body’s real-time glucose level, which can guide the diagnosis and treatment. Therefore, it is necessary to research continuous glucose monitoring (CGM) as it gives us real-time information about our health condition and its dynamic changes. Here, we report a novel hydrogel optical fiber fluorescence sensor segmentally functionalized with fluorescein derivative and CdTe QDs/3-APBA, which can continuously monitor pH and glucose simultaneously. In the glucose detection section, the complexation of PBA and glucose will expand the local hydrogel and decrease the fluorescence of the quantum dots. The fluorescence can be transmitted to the detector by the hydrogel optical fiber in real time. As the complexation reaction and the swelling–deswelling of the hydrogel are all reversible, the dynamic change of glucose concentration can be monitored. For pH detection, the fluorescein attached to another segment of the hydrogel exhibits different protolytic forms when pH changes and the fluorescence changes correspondingly. The significance of pH detection is compensation for pH errors in glucose detection because the reaction between PBA and glucose is sensitive to pH. The emission peaks of the two detection units are 517 nm and 594 nm, respectively, so there is no signal interference between them. The sensor can continuously monitor glucose in 0–20 mM and pH in 5.4–7.8. The advantages of this sensor are multi-parameter simultaneous detection, transmission-detection integration, real-time dynamic detection, and good biocompatibility.

Environmental protection issues are closely related to moral factors, but little research has explored the factors affecting green purchase intention from the aspect of morality. Based on a perspective of ethical decision making, this study investigates the impacts of perceived quality and perceived price on moral intensity and moral judgment, through the moderation of products’ green degree, as well as the impacts of moral intensity and moral judgment on green purchase intention. Research data was collected through a questionnaire survey of 368 consumers in China, and analyzed using a hierarchical linear model. The empirical results reveal that moral intensity and moral judgment significantly promoted green purchase intention. Perceived quality and perceived price both positively affected moral intensity and moral judgment. Products’ green degree positively moderated the relationship between perceived price and moral judgment as well as the relationship between perceived quality and moral judgment. This study provides a new insight into promoting green purchase intention, and the findings may also assist marketers in developing future tactics to increase consumers’ green purchase intention.

There is no consensus on whether environmental commitment can promote green purchase behavior. Especially in the Chinese context, the validity and internal mechanism of the impact of environmental commitment on green purchase behavior have not been deeply studied. Based on Norm Activation Theory and Theory of Planned Behavior, this study explores the influence mechanism of environmental commitment on consumers’ green purchase behavior. Research data were derived from China, and analyzed using randomized control trials. Results reveal that environmental commitment significantly promotes green purchase behavior. Anticipated pride and anticipated guilt mediate the relationship between environmental commitment and green purchase behavior. Social norms moderate the positive effect of environmental commitment on anticipated pride and anticipated guilt. Compared with low social norms, environmental commitment has a greater effect on anticipated pride and anticipated guilt in the case of high social norms. This study provides new insight into environmental commitment and how to promote green purchase behavior, and the findings could help governments and marketers to formulate future policies and strategies to promote consumers’ green purchase behavior.

From the perspective of public rental housing tenants, this paper studies the influential factors of tenants' willingness to vacate.A questionnaire survey was conducted on tenants' willingness to vacate public rental housing in Wuhan city. Statistical data were processed and regression analysis was conducted using the ordered logistic model to study the correlation between factors affecting tenants' willingness to vacate and the confidence to solve their own housing.It is found that the construction area of public rental housing, the tenants' understanding of the nature of public rental housing and the understanding of the legal system of public rental housing are the key factors influencing the tenants' vacating behaviors.
