Summary: China's waste electrical and electronic equipment (WEEE) recycling enterprises rely heavily on government subsidies due to low profitability. Selling carbon credits can offset the government's financial subsidy and contribute to the sustainable growth of the industry. Optimizing appliance-recycling composition can further increase profit growth.

Summary: Government requirements for WEEE management have posed challenges for Brazil due to its vast territory. Implementing circular economy practices is crucial for the competitiveness of Brazilian companies. This study evaluates the reverse chain of WEEE in Brazil, aiming to promote circular economy actions such as recycling, reuse, remanufacturing, and reduction. Key manufacturing decisions are identified, including responsibility for waste management and strategies for selling recycled materials. Recycling and remanufacturing actions are prioritized initially, while also emphasizing the importance of reusing and reducing material consumption beyond immediate problem resolution.

Summary: Globally, E-waste is experiencing unprecedented growth, which will be further fueled by the COVID-19 pandemic. However, governance of E-waste, particularly in the Global South, has been a complex issue. This study investigates the design, adoption, and implementation of E-waste policies in India, a major electronics manufacturing hub with a massive consumer electronics market. The study explores why India adopts seemingly inadequate and ineffective E-waste policy approaches, and attempts to identify alternative approaches.

Summary: Altruistic preference and government subsidies are crucial for stimulating eco-design and recycling in manufacturing-recycling systems. Altruistic preference improves eco-design level and recycling rate, but should be set below a certain threshold. Recycling subsidy is beneficial for both eco-design and recovery, while eco-design subsidy has more complex effects. Subsidies play a crucial role in manufacturing-recycling systems with altruistic preference, but need to be tailored based on specific goals and types of eco-design.

Summary: Waste electrical and electronic equipment (WEEE) management in Port Harcourt, Nigeria is a major environmental challenge. Informal recyclers pose health risks and degrade the environment, while formal recycling faces limitations and lacks guidelines and landfilling opportunities. Introducing a new concept that limits the role of informal recyclers to collection can improve WEEE processing management.

Summary: This paper evaluates the effectiveness of four subsidy schemes on product eco-design and recycling rates in a manufacturing-recycling system using the Stackelberg game theory. The results show that subsidy schemes should be chosen based on market demand and fixed cost coefficients of eco-design, with higher subsidy intensity leading to better supply chain profits and environmental performance but not always better social welfare. Eco-design can effectively increase waste recycling rates, especially when the government subsidizes fixed costs of recyclers.

Summary: Through examining the integration between municipal waste and reverse logistics, the researchers found that the level of municipal waste impacts the recycling of biowaste. They provided a dynamic regression model that can forecast the size of recycled municipal waste into biowaste. The study concludes that the variety of components in municipal waste hinders the increase of recycling rates and suggests a need for changing the components to ones with higher recycling rates.

Summary: The paper introduces an optimization-based simulation approach for designing sustainable management system policies for Waste of Electrical and Electronic Equipment (WEEE). By integrating a system dynamics model and a mixed-integer nonlinear programming model, the proposed approach enhances the representation and performance of WEEE processes. Computational results show that the approach outperforms exclusive system dynamics analysis in both economic and environmental aspects, achieving higher profits and environmental benefits. The model suggests that the cornerstone for improving system performance in the case study is the replacement rate.

Summary: Formal collectors of electronics waste in developing countries are struggling to survive despite initial governmental subsidies. A study proposes an integrated collection scheme that considers on-call and door-to-door demands, and suggests using a capacitated general routing model with time-window for WEEE collection practices. The study shows that significant improvement is achieved with certain capacity and time-management decisions, exploring trade-offs between profit and service-oriented paradigms.

Summary: Ecological poverty alleviation in China is not simply a combination of various policies, but a complex system involving multiple policy instruments, governmental agencies, social forces, and agents. Strengthening interaction among agents, reinforcing connection between elements in policy subsystems, and promoting interactions between subsystems are crucial for achieving win-win outcomes in environmental protection and poverty alleviation in poverty-stricken areas.

Summary: The study investigated the temporal precision of central representations of acoustic signals in patients with schizophrenia, finding that they exhibited poorer detection of interaural correlation, primitive auditory memory, and RBANS score compared to healthy controls. BIC detection accuracy and PAM extent were correlated with RBANS score in both groups, suggesting that schizophrenia impairs temporal precision and higher-order cognitions.

Summary: Since August 2018, African swine fever (ASF) has caused over one million pig deaths in China and led to a surge in pork prices. To address this issue, the Chinese government has implemented two farm subsidies: the compulsory culling subsidy (CCS) and the large-scale breeding subsidy (LBS). Through a game-theoretic model, the study explores the optimal design of these subsidy programs and their impacts on different stakeholders.

Summary: This study examines whether the threshold parameter in the Omega ratio represents risk aversion by analyzing the asymptotic expansions for risk premia. The results suggest that the threshold in the Omega ratio represents risk aversion when the variance of the additional risk decreases with the background risk and when the density of the background risk is log-concave. Comparisons with expected utility criteria indicate that the conditions for the Omega threshold to represent risk aversion are comparable to those for exponential utility functions.

Summary: This paper examines the strategic sourcing decisions of a local brand (BOP) when purchasing remanufactured components from a local supplier (LSP). The study finds that the BOP tends to decrease its purchasing orders from the LSP when the probability of overseas supply disruption is high, while the LSP is willing to sell components to the BOP when the probability is in a moderate range.

Summary: In this study, we investigate a supply chain system consisting of a retailer and a supplier. We examine the threshold problem in contract design and take into account the risk preference of the retailer and the fairness concern of the supplier. The experiment shows that the behavior of the retailer affects the threshold of the optimal contract design, while the behavior of the supplier only affects the optimal wholesale price. These findings suggest that the behavior of retailers and suppliers play a crucial role in the mechanism design of supply chains.
