稳态条件下EDR车速的可信度分析

目的分析稳态条件(例如,无制动)下国内车辆EDR碰前车速的可信度,为EDR碰前车速的应用提供参考。方法在国外研究结论的基础上,选取国内1起既有EDR数据又有监控视频的实际案例,利用监控视频计算所得车速为参考值,分析事故车辆稳态行驶时EDR车速的可信度,并结合EDR车速的来源对其进一步分析。结果根据国外文献研究结果可知,车辆稳态行驶时EDR车速的相对误差在±4%以内。通过国内1起实例的分析,显示稳态行驶车速为120 km/h,EDR记录的碰前车速相对误差为3.886%。结论结合EDR车速来源的分析表明,稳态条件下,国内车辆EDR记录的碰前车速同样具有很好的可信度,可有效应用到相关的车速重建中。     

The Anti-Axial Age

Karl Jaspers famously characterized the period from the beginning of the eighth to the end of the third century before Christ as an “Axial Age” in which intellectual freedom and creativity blossomed as never before. This article argues that it was followed, five hundred years later, by an “Anti-Axial Age”, which devised a novel formula for intellectual and political repression. Its essence was the state’s capture of the millenial narrative, which had first been developed as religious doctrine within Zoroastrianism and Christianity. Involving the two great classical empires of Western Eurasia, Persia and Rome, and then empowering the expansion of Islam, the Anti-Axial Age left an ideological legacy that continues to haunt the contemporary world.     

连接未来:大学的应有之义

大学如何连接一个美好的未来给他们的国家以及他们的学子,这是大学的应有之义.但是目前我国的大学过于关注当下,没有放眼未来.这种状况不仅影响培养质量,而且也是对大学社会责任的弱化.本文指出连接未来应是大学存在的价值所在,要连接未来首先需要植根于人的存在的意义.文中还指出知识的逻辑在改变,教育方式也应该相应地改变.为帮助学生建立复杂问题的视野和善于关联(创新能力的关键),本文提出了几种关联的方式.     

Police Perceptions of Irrational Unstable Behaviours and Use of Force

Police identification of people experiencing mental illness is usually based on either the person having an official contact history with police or through observing behavioural indicators commonly associated with mental illness during an encounter. Police have voiced concerns with their ability to identify and respond to people experiencing mental illness in a timely way and report that they commonly resort to more coercive tactical options to resolve encounters. The present study employed a mixed method design to examine 286 police use of force incidents to investigate the association between force used on and by offenders displaying irrational-unstable behavioural characteristics. The irrational-unstable offenders were two times more likely to be perceived by police to have an apparent mental disorder and almost four times more likely to have a known mental health history; one in six had an official record of contact with mental health services. There were few differences in police and offender use of force, considering force as both a categorical and a continuous variable, while incident-level comparisons suggested that police force was generally proportional to offender resistance. Implications are discussed in terms of the need to redress limitations with the traditional police approach style.
