Integrating nature-based solutions into heritage-sensitive flood risk management
Unfolding the policy dynamics of medical data assetization in Chinese public healthcare institutions
Background: As medical data increasingly functions as a factor of production, public healthcare systems face the challenge of reconciling data-driven innovation with regulatory accountability. In China, a series of national initiatives has sought to promote the assetization of medical data through market-oriented mechanisms. However, existing studies have primarily focused on legal frameworks, technical architectures, and ownership debates, while…
Global trends in the burden of alcohol use disorders in the working-age population from 1990 to 2021 and projections for the next 20 years
Introduction Alcohol use disorders (AUD) have long been among the most disabling mental disorders and a leading cause of health loss. However, data on the burden and trends of these disorders among the working-age population are scarce. Methods This study aimed to assess trends in the burden of AUD among people aged 15-64 years from 1990 to 2021 at the global, regional and national levels and to project future trends. Based on the trend analysis …
Qualitative exploration of negative experiences in counseling clients
摘要: 为了探索我国来访者在心理咨询中的负面体验, 本研究对42名被试进行半结构化一对一访谈, 并进行了现象学主题分析。结果表明心理咨询中来访者的负面体验包括四个主题:一是与心理咨询行业特质相关的负面体验, 包括与心理咨询本身的特点以及与行业发展阶段相关的负面体验; 二是咨访契合度不高, 包括风格不匹配、来访者难以敞开心扉、来访者反感咨询师; 三是与咨询师胜任力相关的负面体验, 包括来访者对咨询师能力与经验、态度、组织管理咨询的方式, 以及伦理方面的不满; 四是对咨询效果的不满意, 包括未能满足来访者的期待, 咨询引发的不良影响, 以及来访者对咨询失望或停止咨询。综上, 文化适应性、咨询中的权力关系不平等等问题对于来访者的体验有突出影响。来访者对咨询师胜任力的不满主要集中在胜任力的基本维度。咨询师应当对来访者的负面体验保持警觉。研究发现为改进本土心理咨询实践和提升咨询质量提供了有益的参考
Who Did What to Whom and How
Self‐efficacy refers to an individual's judgement, belief and perception of their capability to accomplish specific tasks, which is crucial for children's mental well‐being. The primary objective of this scoping review was to systematically examine intervention studies aimed at enhancing children's self‐efficacy in Mainland China, intending to inform social work practices in child services. We conducted a comprehensive search of articles in Web o…

Self-Recognition, Self-Efficacy, and Confidence Intervention of Kunjing Children Without Sufficient Parental Care
Objective: Kunjing children are children in need. This study aimed to evaluate the effectiveness of a pilot trial to promote the self-recognition, self-efficacy, and confidence of kunjing children without sufficient parental care (KCw/oSPC) in Mainland China. Method This intervention was a randomized controlled trial (RCT), 57 KCw/oSPC were recruited and allocated to treatment ( n = 24) and waiting group ( n = 33) randomly. Participants in treatm…

Radiocarbon Dating of Oracle Bones of Late Shang Period in Ancient China
Oracle bone script developed into a sophisticated writing system in Shang Dynasty of China more than 3000 years ago. The systematic scientific dating of oracle bones had not been previously reported. Here we present radiocarbon ( 14 C) dates measured from the sequential samples of oracle bones that pertain to the Shang kings. The results indicate that King Wu Ding (who is called Wu Ting in some literature) reigned during 1254 BC to 1197 BC, and t…
Radiocarbon in the Maritime Air and Sea Surface Water of the South China Sea
Radiocarbon ( 14 C) generated by the thermonuclear tests in the late 1950s to early 1960s has been used as a tracer to study atmospheric and oceanic circulations, carbon exchange between different reservoirs, and fossil fuel emissions. Here we report the first measurements of 14 C in atmospheric CO 2 of maritime air collected over the South China Sea (SCS) during July 2014. We also present 14 C of the dissolved inorganic carbon (DIC) in the sea s…
Seasonal 14 C and Sr/Ca Records of a Modern Coral around Daya Bay Nuclear Power Plants
Due to an increasing number of nuclear reactors in operation, the radiocarbon ( 14 C) released from nuclear power plants (NPPs) has become an important anthropogenic source of 14 C. The examination of seasonal Δ 14 C and monthly Sr/Ca, Mg/Ca variations in a coral in Daya Bay (China) shows that NPPs located there have an impact on the Δ 14 C level and sea surface temperature (SST). The Mg/Ca variation was in good correlation with the Pacific Decad…
A Simple Way to Upgrade a Compact Radiocarbon AMS Facility for 10 Be
A simple way to upgrade the Peking University 500kV NEC radiocarbon facility (CAMS) for 10 Be measurements is presented. In a first phase, a silicon nitride foil as passive boron degrader was mounted in front of the electrostatic deflector near the focal plane of 10 Be. The Si detector at the end of the beam line was replaced with a high-resolution ΔE-E res gas ionization chamber. In addition, a Faraday cup for the measurement of 9 Be 1+ was inst…
AMS Radiocarbon Dating of an Ancient Pottery Workshop in Hepu County, China
An ancient pottery workshop belonging to the Han Dynasty was excavated in Caoxie village, Hepu County. Caoxie village is an important archaeological site in Hepu County, Beihai City, in south China's Guangxi Zhuang Autonomous Region. It is believed that Hepu County was the oldest departure point on the ancient maritime trading route during the Han Dynasty (206 BC to AD 220) due to the ideal natural geographical conditions and the existence of a l…
Radiocarbon dating of charcoal and bone collagen associated with early pottery at Yuchanyan Cave, Hunan Province, China
Yuchanyan Cave in Daoxian County, Hunan Province (People's Republic of China), yielded fragmentary remains of 2 or more ceramic vessels, in addition to large amounts of ash, a rich animal bone assemblage, cobble and flake artifacts, bone tools, and shell tools. The artifacts indicate that the cave was a Late Paleolithic foragers' camp. Here we report on the radiocarbon ages of the sediments based on analyses of charcoal and bone collagen. The bes…
Removal of Contaminants from Oracle Bones During Sample Pretreatment
Animal bones and tortoise shells were used for divination by the Chinese royal family during the Shang Dynasty (∼16th–11th century BC), and the divination results were recorded as inscriptions on oracle bones and shells, which are very valuable cultural remains and record many important events in the Shang Dynasty period. Thus, radiocarbon dating of oracle bones was used to build a precise chronology of the late Shang Dynasty. Due to their origin…

AMS Radiocarbon Dating of Bone Samples from the Xinzhai Site in China
Xinzhai is an important archaeological site discovered 40 yr ago and recently re-excavated in the Henan Province, China. It is believed that the cultural characteristics of the Xinzhai site correspond to the Xia dynasty, the first ancient dynasty of China. Radiocarbon measurements on bone samples from this site were performed at the Peking University AMS facility (PKU-AMS) and the Vienna University AMS facility (VERA). Calibrated ages were obtain…
AMS Radiocarbon Dating of the Fengxi Site in Shaanxi, China
The Fengxi site is near the Feng River in Shaanxi Province, China. Feng City was the capital of the vassal state of Zhou, and the Zhou people lived in this area until the end of the Western Zhou. Serial samples of charcoal, bone, and charred millet were collected from the site and dated by accelerator mass spectrometry (AMS). A sequence model with 6 phases of the Western Zhou dynasty was constructed and the 14 C ages were calibrated with OxCal v …

AMS Radiocarbon Dating of Tianma-Qucun Site in Shanxi, China
Tianma-Qucun is the biggest site of Western Zhou Dynasty discovered in Shanxi Province, China. It has been recognized as the early capital of Jin, a vassal state of Western Zhou. The territories were granted to the first Marquis of Jin with the title in the early days of Western Zhou. Bone sample series from the site were radiocarbon-dated by accelerator mass spectrometry (AMS) and calibrated with the Oxford calibration program OxCal 3.5. Bayesia…
Improvements and Applications of AMS Radiocarbon Measurement at Peking University
AMS radiocarbon measurements were started at Peking University in 1992 with a modified HICONEX 834 ion source. Some archaeological samples were measured at a sensitivity of 10 −14 with ca. 1.7% precision for modern samples. We have made many improvements in our first two years of operation: a high-intensity Cs sputtering ion source was installed; the graphite sample preparation technique was investigated; and the system stability has been improve…
