Environmental commitment to sustainability is one of the most critical issues in the “emerging contaminants”, few studies have examined the role of commitment to pro-environmental behavior and environmental concerns. This study aimed to explore the relationship between environmental commitment and three forms of emotional association: place attachment and social identity, connectedness and concerned about nature. Using 1288 respondents and a structural equation modeling approach, results show that connection to nature enhanced social identity, place attachment, and environmental concern, which in turn increased environmental commitment to sustainability. Place attachment was not related to environmental commitment to sustainability. Further analysis suggested that the theoretical model relationship between connection to nature and environmental commitment to sustainability was mediated by social identity and environmental concern. The findings of this research can offer guidelines for policy makers and green educators who evaluate an environmental commitment so as to provide proper beliefs association with nature and promote social identity and place attachment by emerging contaminants in educational activities. This demonstrates the importance of using a series of robustness of social identity and place attachment instruments and more environmental concern to promote environmental commitment to sustainability. Interpretation of the findings reveals the potential role that environmental commitment to sustainability can play as a hub and catalyst for major emerging contaminants change by fostering recognition of environmental commitment as a way of change and combine schools and government sectors to connect the micro- and macro-levels.

Circular economy products are one of the solutions that can help solve the current environmental crisis and consequently achieve environmental sustainability. The theory of planned behavior (TPB) is the most important social psychological theory to explain individual purchasing behavior. However, the theory lacks a consideration of emotions, green altruism, and other factors. In order to address the research gap, this study proposes and tests a new theoretical model that incorporates variables such as emotions, green altruism, and the willingness to be environmentally friendly (WEF) into its extended model based on the TPB framework, in order to investigate the determinants that have an effect on Taiwanese consumers' purchase intention toward circular economy products. This study also uses multi‐group analysis (MGA) to analyze the moderating effects of WEF on its new theoretical model. It collected data from 387 Taiwanese consumers and analyzed the data using partial least squares (PLS). The research results showed (1) emotions, attitudes, green altruism, and perceived behavior control have a positive effect on consumer purchase intention toward circular economy products; (2) emotions have a positive effect on attitudes, green altruism, subjective norms, and perceived behavior control; and (3) groups with different levels of WEF have significant differences on consumer purchase intention toward circular economy products, in terms of emotions, attitudes, and green altruism. The results of this study can provide a reference for manufacturers and public policy makers to understand how consumers' emotions and green altruism can affect the decision‐making process to making purchase of circular economy products.

Although numerous studies have examined the factors influencing problematic Internet use (PIU), few studies have investigated the interactions between inappropriate physical and mental health (e.g., cyberbullying, Internet pornography, and Internet fraud) as factors facilitating PIU and examined the moderating effect of community bond. Thus, this study analyzed the moderating role of community bond in the relationship between cyberbullying, Internet pornography, Internet fraud, and PIU. Using a cross-sectional survey, adolescents were surveyed through self-report questionnaires. A total of 5,211 responses were received from participant students at 60 senior high schools in Taiwan. Statistical analyses were performed using structural equation modeling. The results indicated that cyberbullying, Internet pornography, Internet fraud, and community bond have significant positive effects on PIU. Community bond has a significant moderating effect in the relationship between cyberbullying, Internet fraud, and the PIU of adolescents. Parental Internet attitude and behavior were found to significantly moderate the relationship between inappropriate physical and mental health, community bond, and PIU. The results suggest that public health and education policies should focus more on adolescents who require additional assistance. Furthermore, school policies could be more informed in regard to relevant psychosocial variables and patterns of Internet use. Finally, this study may serve as a reference for parents, schools, and government education authorities.
