  • Construction and evaluation of an integrated “Hospital-Community-Family” public cardiopulmonary resuscitation training system

    Open AccessYouzhong An, Yanhua An et al.ARTICLEFrontiers in Public Health2025

    Background Epidemiological investigations have found that 80% of cardiac arrest (CA) events occur in public places or homes. Bystander cardiopulmonary resuscitation (CPR) is the most significant factor for out-of-hospital CA (OHCA) survival. Limited opportunities exist for community residents and family members of patients with chronic diseases to participate in CPR training programs. This study establishes an integrated “Hospital-Community-Famil…

  • Work Content of General Practitioners in Beijing, China

    Open AccessYun WEI, Fei‐yue Wang et al.ARTICLEFrontiers in Public Health2022

    Background: Despite the dramatic growth of primary care in China, little evidence showed what general practitioner (GP) do and how GP provided medical service in Beijing. Objective: This study aimed to explore the work content of GPs in primary care in Beijing. Methods: A multi-method study was conducted in five community health service institutions using non-participant observation and critical incident technique interview. Eleven GPs was recrui…

  • Global desertification vulnerability to climate change and human activities

    Open AccessJIANPING HUANG, Guolong Zhang et al.ARTICLELand Degradation and Development2020

    Desertification is the impoverishment of arid, semiarid, and some subhumid ecosystems. The assessment of global scale desertification vulnerability to climate change and human activity is important to help decision makers formulate the best strategies for land rehabilitation and combat global desertification in sensitive areas. There is no global desertification vulnerability map that considers both climate change and human activities. The main a…

  • Modeling Language Components in Mathematical Items Using Multiple Random Effects IRT Models

    Xiangdong Yang, Xiang-Dong YANG et al.ARTICLEActa Psychologica Sinica2012

    摘要: 数学应用题中的语言成分可能对被试问题解决过程产生复杂影响。通常, 这种影响对所有被试并非完全一致, 而是具体数学题目特征与特定被试的认知特性之间交互作用的结果。本研究采用多元随机效应项目反应理论模型的建模方法, 分析了数学应用题中语言成分对问题解决过程的影响。该方法的优势在于它不仅分析了语言成分对数学问题解决过程的平均效应, 同时给出了相应的随机效应, 揭示了相应成分对不同个体问题解决过程的具体影响程度。结果表明, 较难的项目倾向于单词更多, 命题密度更高, 要求对图/表信息进行编码和转译, 或者根据问题表述生成数学公式。项目命题密度影响效应存在着显著的个别差异。项目命题密度对能力较低的被试的影响高于对能力较高的被试的影响

  • Preparative isolation and purification of two isoflavones from Astragalus membranaceus Bge. var. mongholicus (Bge.) Hsiao by high-speed counter-current chromatography

    Open AccessElias Antonio Pizarro, Xiaofeng Ma et al.ARTICLEJournal of Chromatography A2003

    Two isoflavones, calycosin-7-O-beta-D-glycoside and formononetin-7-O-beta-D-glycoside, were separated from n-butanol extract of the root of Astragalus membranaceus Bge. var. mongholicus (Bge.) Hsiao by high-speed counter-current chromatography in two steps using two different solvent systems composed of ethyl acetate-ethanol-n-butanol-water (30:10:6:50, v/v) and ethyl acetate-ethanol-water (5:1:5, v/v). From 200 mg of crude extract, calycosin-7-O…
