This paper investigates grocery store selection among Germans in Greater London compared to native UK residents. Since consumers hold so much power, the grocery retail sector is highly competitive. Additionally, understanding consumer behaviour in urban areas with large numbers of foreign nationals is a complex matter. As internationalisation continues borders are becoming increasingly blurred. Therefore, it is crucial for managers of grocery stores to understand potential cultural differences in terms of store choice. The survey examined the changes, if any, in store choice determinants among Germans living in Greater London compared retrospectively to when they were living in Germany. To provide a comparison, a small group of native UK consumers were also surveyed. The resulting comparison revealed some significant differences and changes in grocery store selection over time. These findings are also likely to be useful for managers in the grocery retail sector when addressing the dynamic nature of transnational mobile and connected consumer markets.

Background: China's power resources are unevenly distributed in geography, and the supply-demand imbalance becomes worse due to regional economic disparities. It is essential to optimize the allocation of power resources through cross-provincial and cross-regional power trading. Methods: This paper uses load forecasting, transaction subject data declaration, and route optimization models to achieve optimal allocation of electricity and power resources cross-provincial and cross-regional and maximize social benefits. Gray theory is used to predict the medium and longterm loads, while multi-agent technology is used to report the power trading price. Results: Cross-provincial and cross-regional power trading become a network flow problem, through which we can find the optimized complete trading paths. Conclusion: Numerical case study results has verified the efficiency of the proposed method in optimizing power allocation across provinces and regions.

In 1973, housewives in California launched what would be the last meat boycott of the twentieth century. And, like its predecessors, the 1973 boycott gained national momentum albeit with little political traction now that Peterson had left public life for a job in the private sector as the consumer advisor to the Giant grocery store chain. And in some quarters of the labor movement, activists drew very clear links between the family economy and the stagnation plaguing workers’ wages. The 1973 boycott led to the founding of the National Consumers Congress, a national organization intended to unite consumer organizers. While it was a short-lived organization, it demonstrates the momentum that consumer activism was building. This chapter also reflects on the lost coordinating opportunity between housewives organizing around consumer issues and the women’s movement in the 1970s.
