Adapting large language models for urban trip purpose inference
Understanding why people travel is fundamental to activity-based travel demand modelling and transport policy analysis. However, conventional trip purpose inference methods typically represent mobility contexts using predefined numerical or categorical features, which may discard semantic information contained in raw contextual data, thereby limiting their ability to represent and distinguish diverse travel-related contexts. To address this gap, …
Isotopic Insights Into the Origins of Cliff Tomb Populations in Ancient Southwest China
Cliff tombs were a distinctive mortuary practice in southern China during the Han dynasty, particularly in the Sichuan Basin, yet the origins and identities of the tomb occupants remain poorly understood. Here we apply multi‐isotope analysis (strontium, oxygen, carbon, and nitrogen) to human and animal remains from two cliff tomb sites in the Sichuan Basin, Gaojiapo and Yuanjingcun, to investigate individual geographic origins and dietary practic…
Evaluating legal mechanisms for combating plastic pollution in the Arctic ocean
Microplastics in the agricultural soils
Microplastics (MPs), as a class of organic pollutants, pose numerous threats to soil. Their accumulation in agricultural soils has garnered significant attention due to the unknown impacts and risks they bring to agricultural production processes. This paper analyzes the source and distribution of MPs in farmland, systematically summarizes the accumulation, adsorption, migration, decomposition, and other pollution behaviors of MPs in farmland soi…

Research progress on the watershed sediment delivery ratio
The watershed sediment delivery ratio (SDR) reflects the transport status of eroded soil in a watershed, and it is an important parameter in studying the relationship between basin erosion and sediment yield of rivers. This review study mainly focuses on China. Based on existing studies of the SDR, this study reviews and summarizes the definition, functions, influencing factors, and estimation methods, research suggestions and prospects of SDR. R…
Herbicide distribution and transport in subsurface environment of a tomato field in the Three Gorges Reservoir area, China
The presence of pesticides via non-point source (NPS) pollution might be a threat to human health and aquatic ecosystems. This study aims to characterize quantitatively the distribution and transport of Linuron in a coupled canopy-soil system by using modelling techniques, viz. an integrated pesticide transport modelling system to simulate three-phase pesticide fate and transport in a tomato field of the Three Gorges Reservoir area. Results indic…
Preferential Policies for Ethnic Minorities and Educational Equality in Higher Education in China
Historically, there have been great socioeconomic disparities and inequalities between China's minorities and the majority Han. As has been discussed in chapters one through three, after the People's Republic of China (PRC) was founded in 1949, influenced by Marxist national theories, the Chinese government instituted preferential policies for minorities to improve their access to education (for principles for policy making, see chapter two; for …
