Agricultural Practices of Rice and Millet at the Largest Zhou Dynasty Settlement by the Weishui River in South-Central China
Understanding how agricultural practices were organised in early complex societies is essential for reconstructing the relationships among subsistence, labour, and social organisation. This study examines Xiangjiazhou, the largest known Zhou dynasty settlement in the Weishui River basin, south-central China, by integrating macrobotanical remains, phytolith evidence, and spatial analysis. The results indicate a rice-dominated agricultural economy.…
Improving the quality of AI-supported K–12 teaching
Artificial Intelligence (AI)-supported teaching is gaining popularity in K–12 schools. However, there have been few empirical investigations on how to improve its quality. To address this gap, this study examined two antecedents of K–12 teachers’ self-reported instructional quality, namely AI-technological pedagogical and content knowledge (AI-TPACK) and self-efficacy in using AI to empower learners (SEEL). Specifically, SEEL is conceptualized in…

Tracing the source of dissolved organic carbon in rivers by carbon isotope (Δ14C-δ13C)
The cycling of carbon in riverine systems is a critical component of global carbon cycle research. However, the sources and performances of riverine carbon in the Qinling Mountains, a pivotal hydrological nexus in China, remain poorly understood. This study investigates the seasonal variations of dissolved organic carbon (DOC) concentration in the Tianyu River within the Qinling Mountains. By utilizing a combination of carbon isotopic signatures …
Exploring the effects of AI literacy in teacher learning
As most practitioners (including teachers) do not know how AI functions and cannot make full use of AI in education, there is an urgent need to investigate teachers’ intentions to learn AI and related determinants so as to promote their AI learning. This study collected survey data from a total of 318 K-12 teachers from sixteen provinces or municipalities in China. A two-step structural equation modeling approach was performed to analyze the data…
The Progress of 14 C-Ams Analysis for Ultra-Small Samples at Xi’an Ams Center
As there exists a growing demand for chronological research and tracer applications using radiocarbon ( 14 C) analyses of samples smaller than 100 μg C, a compact micro-specific hydrogen graphitization method has been developed at the Xi’an Accelerator Mass Spectrometry (AMS) Center. This article describes the performance of the system and the mass of carbon background produced during ultra-small sample preparation. Furthermore, we discuss the re…
Synchronous change in the intensified millet cultivation and ecological environment from the early to middle Holocene on the Inner Mongolia Plateau, northern China
The mechanisms of the origin and dispersal of millet agriculture in northern China are poorly understood. We used plant macroremains, stable isotope compositions of human bone collagen, and pollen records from the Sitai site to reconstruct changes in subsistence strategies and their relationship with the ecological environment from the early to middle Holocene on the Inner Mongolian Plateau in northern China. Charred weed-like seeds, the bones of…
Recent Progress in Atmospheric Fossil Fuel Co 2 Trends Traced by Radiocarbon in China
It is important to know how much of the increased atmospheric CO 2 is derived from fossil fuel emissions. Here, we review the progress in atmospheric fossil fuel CO 2 (CO 2 ff ) tracing over recent years by measurement of Δ 14 C in Chinese cities. In this paper we make progress by expanding the analysis from some locations to more regional views, by combining observations with modeling, and by making a preliminary comparison of observation-derive…
Genetic substructure and admixture of Mongolians and Kazakhs inferred from genome-wide array genotyping
The DevilsCave related ancestry was once widespread westwards covering a wide geographical range from Far East Russia to the Mongolia Plateau. The formation of present-day Mongolic and Turkic-speaking populations has also received genetic influence from agricultural expansion
Human Dietary Complexity in Tianshan Region and the Influence of Climate on Human Paleodiet
With the popularization of carbon and nitrogen stable-isotope analysis methods used on archaeological samples from Xinjiang, the ancient paleodiet there has been revealed. However, research about isotopic analysis combined with environmental factors is rare, especially in such a variable and complex climate as that of the Tianshan region. We systematically analyzed the δ 13 C and δ 15 N results from animals and humans for dietary reconstruction o…

Paleodietary Analysis of Humans in Guanzhong Basin, Shaanxi Province Since 8000 BP
We identified human paleodietary changes from inhabitants of the Guanzhong basin since 8000 BP, based on published carbon and nitrogen isotopic measurements on bones, fauna and plant remains. We also directly measured 14 C ages, δ 13 C and δ 15 N values from bones unearthed at the Zhouyuan site, west of Guanzhong, in order to reconstruct paleodietary changes of the ancient inhabitants. We found that during the Laoguantai period, animal foods were…
C Dating of Soil Organic Carbon (SOC) In Loess-Paleosol Using Sequential Pyrolysis and Accelerator Mass Spectrometry (AMS)
The chemical extraction of soil organic carbon (SOC) fractions from soils often does not produce satisfactory results for radiocarbon dating. In this study, a sequential pyrolysis technique was investigated. The soil was pyrolyzed at temperatures of 200, 400, 600, and 800 °C to partition organic carbon into pyrolytic volatile (Py-V) and pyrolytic residue (Py-R) fractions. The preliminary results show that the 14 C dates of both fractions become p…
