Confidence intervals,significance values,maximum likelihood estimates,etc. sharpened into Occam’s razors

Abstract

Confidence sets, p values, maximum likelihood estimates, and other results of non-Bayesian statistical methods may be adjusted to favor sampling distributions that are simple compared to others in the parametric family. The adjustments are derived from a prior likelihood function previously used to adjust posterior distributions.     

英汉互译中的音义对应及其可译性限度

声音、节奏等具有伴随意义,有时是对语言本身意义的补充.在翻译时力求音义对应是实现等效翻译的一种重要手段.当然,英汉语音在结构、功能和表达方式上的差异也使音义对应有一定的限度.     

Holistic trajectories: a study of combined employment, housing and family careers by using multiple-sequence analysis

Summary.  Social science applications of sequence analysis have thus far involved the development of a typology on the basis of an analysis of one or two variables which have had a relatively low number of different states. There is a yet unexplored potential for sequence analysis to be applied to a greater number of variables and thereby a much larger state space. The development of a typology of employment experiences, for example, without reference to data on changes in housing, marital and family status is arguably inadequate. The paper demonstrates the use of sequence analysis in the examination of multivariable combinations of status as they change over time and shows that this method can provide insights that are difficult to achieve through other analytic methods. The data that are examined here provide support to intuitive understandings of clusters of common experiences which are both life course specific and related to socio-economic factors. Housing tenure is found to be of key importance in understanding the holistic trajectories that are examined. This suggests that life course trajectories are sharply differentiated by experience of social housing.     

宋明理学与中华民族精神

宋明理学是中国古代社会后期别具特色和风格的哲学思维形态。它被统治阶级奉为官方哲学,长达六七百年之久,支配着我国经济、政治以及文化思想的发展。由于它构建了一套严谨的极具思辨性的理论体系,把先前儒家所提出的伦理纲常上升到宇宙本体论的高度,从而强化了爱国主义,反映了时代的共同价值取向,提升了中华民族对于崇高精神境界的追求,正是这些承担并体现了形成与发展中的中华民族精神,是锤炼和塑造当代中华民族精神的文化土壤。

寻根文学民族化追求的回顾与思考

新时期寻根文学的民族化追求是新时期文学民族化意识高涨的结果和表现。内容、形式上多方面的民族化努力体现了民族化追求的成就,但其意义上的虚空和内容上的故事化、传奇化的走向,使寻根文学民族化追求走向了片面和形式。寻根文学对民族文化的“根”的夸张、放大式的集中写照,在充分展示民族化的同时,也导致了“后殖民主义文化景观”的出现,最终使得80年代中期中国作家的民族化追求走向了瓦解。

Bayesian locally optimal design of knockout tournaments

The elimination or knockout format is one of the most common designs for pairing competitors in tournaments and leagues. In each round of a knockout tournament, the losers are eliminated while the winners advance to the next round. Typically, the goal of such a design is to identify the overall best player. Using a common probability model for expressing relative player strengths, we develop an adaptive approach to pairing players each round in which the probability that the best player advances to the next round is maximized. We evaluate our method using simulated game outcomes under several data-generating mechanisms, and compare it to random pairings, to the standard knockout format, and to two variants of the standard format.     

降低线性调频脉冲压缩信号旁瓣的方法

讨论线性调频脉冲压缩信号距离旁瓣的抑制。研究如何降低小时带积线性调频信号距离旁瓣电平问题,针对该信号频谱矩形特性差,提出了采用频谱修正方法来提高脉冲压缩信号的主副比。该方法具有全数字式处理特点,适宜使用IMS A100器件实现脉冲压缩处理。计算机模拟结果表明,无论是小时带积还是大时带积的线性调频信号,经谱修正后,脉冲压缩信号的主副比均舍得到提高。
