1075年遼宋国境画定交渉（於開封）について : 「梁頴墓誌」理解のために
No full textThe epitaph of Liang Ying 梁頴, who was an official of the Liao 遼 dynasty, was discovered in Zhuozhou 涿州 city, Hebei 河北 province, China in 2010. Because Liang Ying engaged in the so-called "territorial negotiations" held by Liao dynasty and Northern Song 宋 in the 1070s, we can find a description on the negotiations in the epitaph. There is a significant difference in the circumstances of historical materials between the Liao dynasty and Northern Song, which means the discovery of this description from Liao side material is considered extremely valuable. In the epitaph, part of a letter from the emperor of Northern Song to Liao dynasty in 1075 was cited, enabling us to recognize that the author of the epitaph regarded it as important in terms of the negotiations at Kaifeng 開封, in 1075. From this reason, the negotiation was a major consideration of this article. Specifically we examined the article of bingyin 丙寅, forth month, eighth year of Xining 煕寧(1075), of Xu-Zizhitongjian-changbian 続資治通鑑長編 volume 262.本研究は、日本学術振興会の科研費(15K16851)の助成をうけたものである。departmental bulletin pape
Examining the impacts of ethnicity on space-time behavior: Evidence from the City of Xining, China
No full textRecent studies on racial or ethnic differences have moved beyond the residential neighborhood to understand segregation in terms of people's space-time behavior. In China, where the spatial distribution of ethnic minorities is quite different from Western countries, research on ethnic issues based on this new perspective to date has received far less attention than other social issues such as poverty. This study seeks to examine the effects of ethnicity on people's space-time behavior in the Chinese context. Focusing on the Hui minorities and the Han majorities in Xining, a multi -ethnic city in the western region of China, we examined the space-time patterns of daily activities of these two ethnic groups. We use geovisualization tools and statistical measures to explore the extent to which ethnicity accounts for the differences in space-time behavior between the two ethnic groups. The paper concludes that ethnic characteristics of the Hui minorities, such as gender division of domestic labor ' and the participation in spatially and temporally fixed daily religious activities, have led to an independent and significant influence of ethnicity on space-time behavior when compared with the Han majorities in Xining.

A Late Eocene palynological record of climate change and Tibetan Plateau uplift (Xining Basin, China)
No full textInternational audienceClimate models suggest that Asian paleoenvironments, monsoons and continental aridification were primarily governed by tectonic uplift and sea retreat since the Eocene with potential contribution of global climate changes. However, the cause and timing of these paleoenvironmental changes remain poorly constrained. The recently well-dated continental mudflat to ephemeral saline lake sedimentary succession, situated in the Xining Basin at the northeastern margin of the Tibetan Plateau (NW China), provides a unique opportunity to develop additional proxy successions in this area that are placed accurately in time. Here, a palynological record from this succession is reported. High abundances of desert and steppe-desert taxa such as Ephedripites and Nitrariadites/Nitraripollis are found, which can be differentiated by the presence of broad leaved deciduous forest taxa in the lower part of the section (particularly up to 36.4 Ma; magnetochron C16r), and a sudden increase of Pinaceae (Pinuspollenites, Piceaepollenites and Abiespollenites) which is dated at 36.1 Ma (C16n.2n). Coexistence Approach (CoA) indicates that from 39.9 to 36.4 Ma (C17n.1n) regional climate was warm and wet, while from 36.4 to 33.5 Ma (C16n.2n-C13r) climate tends to be cooler and drier. The data indicate that paleoenvironmental and palynological changes on the NE part of the Tibetan Plateau resulted from a combination of long-term tectonic uplift forcing and long- and short-term climate changes. The increase of taxa such as Piceaepollenites and Abiespollenites indicates not only a cooling and drying trend prior to the Eocene/Oligocene (E/O) boundary, but also the existence of high altitude mountain habitats in the periphery of the Xining Basin. The sudden Pinaceae event correlates closely in time with a marked aridification step as viewed from the lithology of the Xining Basin that was linked to the sea retreat out of the Tarim Basin
Health impacts of a cold wave and its economic loss assessment in China’s high-altitude city, Xining
No full textAbstract Objective Amidst climate change, extensive research has centered on the health impacts of heatwaves, yet the consequences of cold spells, particularly in cooler, higher-altitude regions, remain under-explored. Methods Analyzing climatic data and non-accidental mortality in Xining, China’s second-highest provincial capital, from 2016 to 2020, this study defines cold spells as daily mean temperatures below the 10th, 7.5th, or 5th percentiles for 2–4 consecutive days. A time-stratified case-crossover approach and distributional lag nonlinear modeling were used to assess the link between cold spells and mortality, calculating attributable fractions (AFs) and numbers (ANs) of deaths. The study also examined the impact of cold spells over different periods and analyzed the value of a statistical life (VSL) loss in 2018, a year with frequent cold spells. Stratified analyses by sex, age, and education level were conducted. Results A significant association was found between cold spells and non-accidental mortality, with a relative risk of 1.548 (95% CI: 1.300, 1.845). The AF was 33.48%, with an AN of 9,196 deaths during the study’s cold period. A declining trend in mortality risk was observed from 2019–2020. The 2018 VSL was approximately 2.875 billion CNY, about 1.75% of Xining’s GDP. Higher risks were noted among males, individuals aged ≥ 65, and those with lower education levels. Conclusion The findings underscore the vulnerability and economic losses of high-altitude cities to cold spells. Implementing interventions such as improved heating, educational programs, and community support is vital for mitigating these adverse health effects
Rival as Villain: How Moral and Threat Language in American News Coverage Influences Public Opinion about China
No full textThe present study explores how moral and threat language in news media influences public opinion within the context of the U.S.-China relationship. Drawing on Moral Foundations Theory and Intergroup Threat Theory, I employed a computational approach combining the dictionary method with Large Language Models to identify moral and threat language in coverage of China by six major U.S. news outlets from 2005 to 2022. I then analyzed the relationship between distinct types of moral and threat language and longitudinal polling data on Americans’ attitudes toward China. The results reveal a unified pattern: both liberal- and conservative-leaning outlets employed more binding than individualizing moral language, and emphasized realistic threats over symbolic threats when covering China. However, it is symbolic threat language that more strongly correlates with negative attitudes toward China. Furthermore, realistic threat language only predicted negative attitudes when accompanied by sufficient levels of moral language, with this relationship intensifying as moral language increased. The findings offer insights into the moral and threat dimensions of foreign news and public opinion towards foreign countries, highlighting a critical and complex interplay between these elements in a global context

Evidence for northeastern Tibetan Plateau uplift between 25 and 20 Ma in the sedimentary archive of the Xining Basin, Northwestern China
No full textThe growth history of the Tibetan Plateau provides a valuable natural laboratory to understand tectonic processes of the India-Asia collision and their impact on and interactions with Asian and global climate change. However, both Tibetan Plateau growth and Asian paleoenvironments are generally poorly documented in pre-Pliocene times and reflect limited temporal coverage for different parts of the plateau. Here we present magnetostratigraphic results from the Xining Basin, at the NE margin of the Tibetan Plateau, precisely dating the record between the earliest Oligocene (similar to 33 Ma) to the middle Miocene (similar to 16 Ma). The pattern of observed paleomagnetic polarity zones is unequivocally correlated to the geomagnetic polarity time scale (GPTS) indicating relatively constant and low sediment accumulation rates (32 m/Myr) except for a peculiar period of unstable accumulation between 25.3 and 19.7 Ma. At the beginning of this interval, a marked permanent increase in magnetite content of the sediments is observed and likely relates to a change in provenance. We directly relate this unstable period of sediment accumulation and provenance change to the coeval exhumation recently reported by low-temperature thermochronology from the Laji Shan range, which subsequently formed the southern margin of the Xining Basin. Evidence for NE Tibet tectonism at 25-20 Ma can be associated with widespread deformation over the entire Himalayan-Tibetan orogen at this time, which may be linked to the coeval appearance of monsoon climate in Eastern Asia and the onset of central Asian desertification.
