The article is devoted to the issues of political and legal regulation of climate adaptation in the regions of the Russian Federation. Against the background of the adopted federal national adaptation plan, regions are tasked with identifying key areas of activity taking into account natural-climatic, demographic, environmental and technological specifics. The authors focus on the similarities and differences of the presented adaptation plans, emphasizing that work to improve this system continues within the framework of Russia’s international obligations. The Arctic regions deserve special attention, as they also differ from each other both in the selected climate adaptation activities (from ecology to energy saving) and in their number. This review provides a clear picture of how the federal ecological system can develop.

The relationship between new-quality productivity and educational equity is characterized by close mutual influence and co-evolution. Driven by technological innovation, new-quality productivity is profoundly transforming the economic and social landscape. Educational equity, a crucial component of social justice, is vital for ensuring equal development opportunities for all individuals. The robust growth of new-quality productivity not only optimizes the distribution of educational resources and enhances educational quality but also poses new challenges and demands for equity in education. In turn, the continuous advancement of educational equity provides a solid talent foundation and a conducive environment for innovation to new-quality productivity. These two aspects intertwine and progress together in various domains, including policy systems, cultural values, and educational practices. This interplay highlights the central role of new-quality productivity and educational equity in societal development, while also demonstrating their dynamic and complementary relationship.

With the rapid development of global e-commerce, cross-border e-commerce has become an important force in promoting international trade and economic globalization. Due to the rapid development of cross-border e-commerce, the number of online disputes is gradually increasing. These disputes demonstrate their complexity and diversity in terms of legal application, evidence acquisition, and enforcement. Tmall Global is a cross-border e-commerce platform under the Chinese e-commerce giant Alibaba Group. This study takes Tmall Global as an example to analyze the characteristics of disputes on this platform and explore the current situation of online disputes in cross-border e-commerce. Drawing on the experience of online dispute resolution in the European Union, ASEAN, and other regions, this article proposes a series of suggestions to improve China’s cross-border e-commerce online dispute resolution mechanism, including enhancing the platform’s own dispute resolution capabilities, strengthening international cooperation and artificial intelligence, optimizing dispute resolution processes using large data and cloud computing, strengthening consumer rights protection, and optimizing legal and regulatory frameworks. The aim is to provide an effective dispute resolution mechanism for China’s cross-border e-commerce platforms and provide useful reference for other countries.

An investigation is conducted into how radiation affects the non-Newtonian second-grade fluid in double-diffusive convection over a stretching sheet. When fluid is flowing through a porous material, the Lorentz force and viscous dissipation are also taken into account. The flow equations are coupled partial differential equations that can be solved by MATLAB’s built-in bvp4c algorithm after being transformed into ODEs using appropriate similarity transformations. Utilizing graphs and tables, the impact of a flow parameter on a fluid is displayed. On velocity, temperature, and concentration profiles, the effects of the magnetic field, Eckert number, and Schmidt number have been visually represented. Calculate their inaccuracy by comparing the Nusselt number and Sherwood number values to those from earlier investigations.
