Comparing the impact of educational messages based on an extended parallel process model on solid waste separation behaviors in female students: A four-group randomized trial

Practice and performance of domestic waste source segregation in Chinese universities: A case study in Shanghai

The importance and urgency of domestic solid waste (DSW) source segregation in universities is self-evident. Although many universities have carried out waste management, however, a comprehensive summary for successful implementation work of DSW segregation is lacking. This study summarizes the mechanism of DSW segregation in Chinese university based on questionnaire survey, on-site inquiry and sampling analysis in a comprehensive university in Shanghai. Questionnaire survey show that it is critical for encouraging students to participate in waste segregation to build convenient segregation facilities and humanized segregation reward and punishment method. The strengthened publicity and education due to the advantages in environmental discipline, easy-operating waste dumping site/facility as well as personalized solutions for different functional areas (teaching building) were considerably important strategies for implementing efficient waste segregation. The recyclables that were collected by intelligent recycling device and mobile recycling enterprise were dominated by paper, and the amounts increased dramatically during the graduation season. Therefore, the university correspondingly increased the collection frequencies of waste and the number of segregation guiders in the period to decrease the potential risk of fire safety. The study could provide a valuable reference for efficient implementation of waste segregation on university/college in China.

The integrated study of the effects of infographic design on waste separation behavior and the behavioral outcome implementation on waste composting

This study revealed the effects of designed infographics for waste separation and the implementation of behavioral outcomes using surveys and lab-scale experiments. The designed infographics improved the waste separation behaviors of the respondents in term of subject norm, perceived behavioral control, and intention. These influential factors were increased by 5.84 to 20.5%. The effects of design elements including waste separation mascots, the knowledge of waste separation, and the knowledge of waste management were dependent on the ratio of graphics and messages. Therefore, the careful attention on design elements of the infographic had to be noted. According to survey results, animal bone and shell wastes were the highest miss-sorting waste for the compostable waste bin. Although the contamination rate of these wastes did not significantly affect the decomposition of organic waste in the composting process, the quality of the product was degraded in term of toxicity. The germination index was decreased by 66.0% under a 10% contaminated condition. In contrast, the increased the total Ca of compost was increased. Furthermore, the other chemical components of final composts were similar under various conditions. It could be concluded that the mixture of animal bone and shell in compostable waste is acceptable for the purpose of waste reduction. However, the contamination rate of inappropriate wastes in the compostable waste bin should be minimized to enable effective waste composting. The significant findings of this study will be able to apply to the design of waste separation at the source and the plan of waste management.

Design and evaluation of two educational media in the form of animation and games to promote the cutaneous leishmaniasis prevention behaviors in adolescent female

BACKGROUND

Cutaneous leishmaniasis (CL) has social and psychological effects on different groups, especially adolescents and young girls in 98 countries of the world, in addition to the economic burden. Therefore, it is necessary to apply effective methods for CL prevention. In this study, educational messages were designed based on Extended Parallel Process Model in both forms of animation and game, whose effect on the cutaneous leishmaniasis prevention behaviors was evaluated in adolescent female students.  METHODS: This experimental study was carried out from January to September 2021 on 275 adolescent female students in Isfahan province, Iran. Cluster sampling method was used, and then the students were randomly divided into three groups, namely animation education, game education, and control groups. The educational intervention was performed with two new media in the form of animation and games. The data collected before and two months after the education through a valid and reliable researcher-made questionnaire were analyzed in SPSS24 software using statistical tests of ANOVA, Chi-square, paired t and analysis of covariance (ANCOVA).

RESULTS

The mean age of the participants was 14.07 ± 0.94. The mean scores of behavior in the animation group (60.60 ± 23.00), the game group (61.70 ± 22.05), and the control group (66.13 ± 24.62) were not significantly different prior to the education. However, after the education, there was a significant difference between the animation (80.66 ± 17.62) and game groups (82.58 ± 19.07) and the control group (69.79 ± 23.29) (P < 0.001). The mean scores of model constructs following the intervention (susceptibility, severity, response efficacy, and perceived self-efficacy) significantly increased in the animation and game groups compared to that in the control group (P < 0.05).

CONCLUSION

The results showed that if educational programs contain a combination of threat and efficiency messages, CL-preventive behaviors in adolescents increase. Providing similar educational content with both game and animation methods indicated that both methods had an almost same effect. Although animation production is more costly, it has the advantage of being used in periods and for other adolescents.

The Use of Social Networking Sites and Pro-Environmental Behaviors: A Mediation and Moderation Model

Climate change poses a huge threat. Social networking sites (SNSs) have become sources of human-environment interactions and shaped the societal perception of climate change and its effect on society. This study, based on the extended parallel process model, aims to examine the effect of exposure to climate change-related information on SNSs on the pro-environmental behaviors of individuals. The study examines the mediation effect of fear of victimization from climate change between the exposure to climate change-related information on SNSs and pro-environmental behaviors, including the moderation effect of attention deficit and decision-making self-efficacy with the help of appropriate instruments. A total sample of 406 reliable questionnaires were collected from students using SNSs in China, and data were analyzed through SPSS and AMOS. Results indicate that the exposure to climate change-related information on SNSs has a direct positive effect on users' pro-environmental behaviors (β = 0.299, p < 0.01). Fear of victimization from climate change also mediates the relationship between exposure to climate change-related information on SNSs and pro-environmental behaviors (β = 0.149, SE = 0.029, p < 0.01). In addition, attention deficit moderates the relationship of exposure to climate change-related information on SNSs with fear of victimization from climate change (β = -0.090, p ≤ 0.01) and pro-environmental behaviors (β = -0.090, p ≤ 0.05). Similarly, the relationship between fear of victimization from climate change and pro-environmental behaviors is moderated by decision-making self-efficacy (β = 0.267, p ≤ 0.01). The findings offer implications for media organizations and government policy makers, who should post or spread environmental information through the most trustworthy media, with trustworthy sources, in an effective manner, and without exaggerated adverse impacts.
