With the approval of the Chinese Academy of Sciences and the German Ministry of Science & Education, this year will see the establishment of another MPG junior research group at the Kunming Institute of Zoology (KIZ). The institute has been seeking all over the world for a scientist to head the group. The first such group was set up at the KIZ in 2001, with Dr. Wang Wen from the University of Chicago as its head. ……展开更多

文摘Overview The research group for nonlinear dynamics and complex systems is a virtual team comprised of some young re- searchers of common research interest in the School of Physics and Information Technology with the aim of improving the local academic environment and promoting scientific collaborations domestically and worldwide. The research interest of the group is currently focused on the dynamical behaviors of various nonlinear systems, with the subjects investigated ranging from classical to quantum systems, from low dimensional to spatiotemporal systems.
文摘目的:描述通辽市社区居民老年期痴呆流行病学调查的抽样设计、权重计算、调查工具、现场执行及质量控制方案。方法:采用三阶段不等概率抽样设计在内蒙古自治区通辽市调查65岁及以上的常住居民,采用10/66老年期痴呆系列研究(10/66 Dementia Research Group,10/66 DRG)评估工具获得老年期痴呆的疾病诊断,以计算机辅助个人访谈模式开展调查,并实施调查全程及时质量控制措施。结果:在通辽市9个旗/县/市/区的166个嘎查/村/居中共调查老人4345人,应答率为96.2%。计算抽样设计权数、无应答调整权数和事后分层调整权数后,将上述权数相乘并进行极值调整和标化调整,从而获得最终权数。171名访员接受培训,考核合格后开展入户调查,并采用计算机数据核查、录音核查和电话核查等质量控制措施,保证调查的真实性。结论:本调查采用严格的抽样设计和质量控制措施实施调查,并采用国际效度和信度满意的10/66DRG评估工具作为调查工具,具有国际跨文化可比性,可以为国内其他地区开展老年期痴呆流行病学调查提供方法学参考。
