With the accelerated iteration of global electronic and electrical product updates, the demand for electronic and electrical products presents a new trend in which the life cycle of electronic and electrical products is shortened. Waste electrical and electronic equipment (WEEE) products pose a great threat to the global ecological environment, and solving this problem is urgent. Therefore, governments around the world have formulated funding policies for WEEE products, which has led to continuous improvements in such policies. Along these lines, we adopt the circular economy concept, extended producer responsibility theory and life cycle assessment method to comparatively analyse and compare the different fund operation modes in China, Germany, Japan and The Netherlands. In addition, based on the data related to fund policy implementation, we point out the problems in the development of the WEEE industry in China. The analysis results show that although China is the largest WEEE market, it is still in the initial stage and lags behind Western countries in efficiency and cost management. Then, taking as an example 'Go Green', an O2O classified recycling platform launched in 2005, this paper performs an extended analysis of the "Internet +" recycling model, which was proposed as a WEEE fund operation solution in China. Finally, we discuss the economic impact of this study on the future implementation and valuation of WEEE fund policy.

AbstractThe present study tested how 5‐ to 6‐year‐old and 7‐ to 8‐year‐old children allocate with in‐group collaborators according to merit in the context of external between‐group competition. Children (N = 310) first were asked to collaborate with a high‐ or low‐merit partner to complete an intergroup game in the form of competition (further divided into win and lose conditions) or noncompetition. Afterward, they were asked to allocate, reason about, and express their expected allocations toward the in‐group collaborator. We found that 5–6‐year‐olds allocated meritoriously with collaborators in the first‐party context. In contrast, 7–8‐year‐olds were affected by external between‐group competition. Specifically, compared with the noncompetitive condition, 7–8‐year‐olds conducted equal or roughly equal allocations with the in‐group collaborator and referenced Equality and Affiliation more frequently in the win and lose conditions. Furthermore, both 5–6‐year‐olds and 7–8‐year‐olds expected teachers to allocate meritoriously across the win, lose and noncompetitive conditions, indicating that they realized that social norms require them to make allocations based on merit rather than social relationships. The findings suggest that with age, children weighed the moral concerns of merit and the social concerns of in‐group harmony when determining the allocation of resources.

The performance of the battery used in the traditional solar photovoltaic power generation system is poor, and the solar energy has a certain volatility, which makes the performance of the solar photovoltaic power generation system decline significantly. In order to improve the performance of the solar photovoltaic power generation system, a solar photovoltaic fuel cell combined power generation system has been developed. However, there are some problems in the process of traditional combined generation system optimal scheduling, such as high investment cost and total cost, and short generation time of optimal scheduling scheme. This paper takes solving the problems of traditional system optimal scheduling as the research goal, a new optimization scheduling method of solar photovoltaic and fuel cell combined power generation system was designed. The composition and topological structure of the solar photovoltaic fuel cell combined power generation system are analyzed. The system is composed of photovoltaic array, fuel cell, electrolytic cell, short-term energy storage unit and energy control unit. It can mainly convert sunlight radiation into electric energy, and convert it into DC or AC used by people through multiple links, so as to ensure the stability and security of power supply in our country. A scheduling model is established according to the photovoltaic cell power generation model, the fuel cell power generation model, the electrolytic hydrogen production model, the battery model, the power conversion model and the combined power generation system model. And the multi-objective cuckoo algorithm is used to solve the model, the optimization scheduling results of solar photovoltaic fuel cell combined power generation system are obtained. The experimental results show that the total investment cost of this method is reduced by 123678.4 yuan and 175858.7 yuan compared with the experimental comparison method, and the total cost is reduced by 301195.5 yuan and 414991.8 yuan compared with the experimental comparison method. It shows that compared with the experimental comparison method, the total investment cost and total cost of this method are lower, and the generation time of the optimal scheduling scheme is between 0.19s and 0.25s, and the practical application effect is good. It fully solves the problems existing in the traditional methods and has certain application significance.

AbstractAs children develop, they are exposed to social norms that help them adapt to society. Here, the current study used an adapted dictator game to investigate whether exposure to a generous norm (sharing 80 yuan) or a selfish norm (sharing 20 yuan) would influence the sharing behavior of children. Participants were 1983 third‐ to fifth‐graders from five primary schools in mainland China (two in Beijing and three in Shandong). Norms were presented in the written format in which children were told the amount of personal resources that most of their parents/teachers/peers shared with a recipient (descriptive norms) or thought they should share with a recipient (injunctive norms). The results showed that children were more affected by generous norms than selfish norms. Moreover, when presented with generous norms, children were more sensitive to descriptive norms than to injunctive norms and they shared more when they were exposed to selfish descriptive norms than selfish injunctive norms. Additionally, children shared more and were more likely to comply with norms from teachers and peers in the generous condition, but they were less likely to comply with peers and deviated more from the undesirable norm from peers in the selfish condition. Together, our findings indicate the crucial importance of social norm information for the promotion of children's sharing behavior in China.

With the popularity of mobile Internet technology, mobile government has become the mainstream of current government affairs management, which highlights the growing importance of exploring citizens' intention to adopt m-government. To find the important driving factors of m-government adoption and understand what roles the cultural and technical development level play in it, this study conducted a meta-analysis to search for important factors in m-government adoption from 42 studies from 17 countries. Based on the socio-technical theory, this study applied a meta-regression to explain the differences in the effects of these factors, from the perspective of culture and technical development level. The results show that perceived usefulness, perceived ease of use, attitude, social influence, perceived compatibility and trust all play important roles in m-government adoption. Culture and technical development level play moderating roles on the above relationships except for the perceived ease of use–perceived usefulness path. Our findings also reveal that the joint moderating effect of cultural and technical development level can better explain the impact of environmental factors on m-government adoption and consequently provide suggestions for the future implementation of m-government in different countries with diverse cultures. Points for practitioners This study proposes a research model of m-government adoption. Public managers should focus on citizens' perceived usefulness, perceived ease of use, attitude, social influence, perceived compatibility and trust, so as to improve citizens' intention to use. The results also confirm that culture and technical development level have a specific moderating effect on m-government adoption, which means that public managers should not only consider service quality, but also note environmental factors. They especially should consider the flexible mobile government development strategies in different countries.

AbstractPrevious research has found that children can engage in rectification of pre‐existing inequality by allocating more resources to individuals and groups of disadvantaged status, but less research has investigated how children address the inequalities using resources of different values, especially when they are linked to group membership (i.e., in‐group or out‐group member) in the first‐party (Study 1) and third‐party contexts (Study 2). To address these issues, children aged 5–6 years and 7–8 years were assigned four distribution tasks in each study, in which they were asked to allocate resources of different values to disadvantaged or advantaged persons who were either in‐group or out‐group members and then, reason about their decisions. We found that children used resources of different values to rectify inequalities in the intergroup context overall. Specifically, younger children demonstrated group bias in their rectification of inequalities in both first‐ and third‐party contexts whereas older children overcame group bias and were more concerned about inequality status during allocation. Thus, with age, children were better able to deal with the conflict between inequality status and group bias using resources of different values.
