论中西教育思想交会

西方式的教育思想在当下的中国教育领域逐渐成为集体无意识,中国本身的教育理念反而不受重视。谈论中西教育思想交会,首先就意味着"自我"与"他者"的视角融合。研究东西方传统教育思想的内在分歧,根本主旨也在于对问题作一学术性的探讨,东西方教育思想的种种区分,本质上是意境、德化与逻辑、知识的差异,这种差异在文化与社会的发展中塑造了不同的社会性格与人文面貌。     

试论斯宾诺莎的自由人思想及现代意义

以成为自由人为基点，斯宾诺莎观照了成就人自由的方方面面。他认为自由意味着与成就完满人生的要求相一致的所有有关的方面的充分展开与和谐；自由人一定是依据理性为指导的人、是尊重并热爱自然的人、是身心和谐发展的人、是和他人和睦相处的人、是遵守法律的人。自由是人类追求的目标，斯宾诺莎关于自由人的深刻思考，在今天仍有其普遍的全人类的正面价值，值得我们重视和探讨。     

A comparative evaluation of objective and subjective weather forecasts in the united states

This paper is concerned primarily with the evaluation and comparison of objective and subjective weather forecasts. Operational forecasts of three weather elements are considered: (1) probability forecasts of precipitation occurrence, (2) categorical (i.e. non-probabilistic) forecasts of maximum and minimum temperatures and (3) categorical forecasts of cloud amount. The objective forecasts are prepared by numerical-statistical procedures, whereas the subjective forecasts are based on the judgements of individual forecasters. In formulating the latter, the forecasters consult information from a variety of sources, including the objective forecasts themselves. The precipitation probability forecasts are found to be both reliable and skilful, and evaluation of the temperature/cloud amount forecasts reveals that they are quite accurate/skilful. Comparison of the objective and subjective forecasts of precipitation occurrence indicates that the latter are generally more skilful than the former for shorter lead times (e.g. 12–24 hours), whereas the two types of forecasts are of approximately equal skill for longer lead times (e.g. 36–48 hours). Similar results are obtained for the maximum and minimum temperature forecasts. Objective cloud amount forecasts are more skilful than subjective cloud amount forecasts for all lead times. Examination of trends in performance over the last decade reveals that both types of forecasts for all three elements increased in skill (or accuracy) over the period, with improvements in objective forecasts equalling or exceeding improvements in subjective forecasts. The role and impact of the objective forecasts in the subjective weather forecasting process are discussed in some detail. The need to conduct controlled experiments and other studies of this process, with particular reference to the assimilation of information from different sources, is emphasized. Important characteristics of the forecasting system in meteorology are identified, and they are used to describe similarities and differences between weather forecasting and forecasting in other fields. Acquisition of some of these characteristics may be beneficial to other forecasting systems.

关于"四不等田"的一点注记

分析了《中国科学技术典籍通汇》本中《杨辉算法》的一个注记 ,得出结论 :这个注记应写于明代刊刻之时 ,从而得出两个推论 :1.中国古代数学的“中断”应由元末 ( 130 3)推迟到明初 ( 1378或 14 31) ;2 .中国古代数学界是十分重视并进行学术交流的 .

论我国刑事发回重审制度之重构

我国刑事发回重审制度存在诸多弊端,其发展前途在于走改革之路。改革的重点包括明确发回重审的适用条件,适当控制发回重审的适用范围,严格限制发回重审的次数,增加发回重审的方式等。     

在媒体流调度中改进的DRR算法

提出了模糊控制变权法多因素决策的自适应DRR算法(VWADRR)———一种改进的亏损轮询调度算法(DRR)。算法应用在调度多个媒体数据流队列时。算法基于模糊控制理论中的多因素决策,具体使用了变权法。可以自适应输出信道的带宽和输入队列的缓存余额。变权法根据可用带宽和队列缓存余额这两个因素做出决策,动态地确定DRR中的常量QN。由于考虑了每个数据包发送的时限,降低了每个数据包的延时。使系统在大流量的情况下有效利用缓存和带宽,降低缓存耗光的可能性,同时平滑了突发。     

高速列车隧道内会车时气动舒适性研究

基于N-S方程及k-ε两方程紊流模型,采用有限元法对2列高速列车在隧道内交会时引起的车内压力变化及各参数对乘坐舒适性的影响进行了仿真分析.研究结果表明:2列高速列车在隧道内会车时的瞬变压力值与列车会车的地点、列车长度、列车速度及列车的密封指数均有关系,同车长、车速、密封指数的情况下,会车在隧道中部时瞬变压力变化值最大;同隧长、车速、密封指数的情况下,会车于相同地点时,较长车长的瞬变压力最大变化值要高于较短车长的;当列车的密封指数大于15s时,各种计算工况均能满足列车内瞬变压力容许值1.25kPa/3s的评价标准.
