也谈"错案追究制"

错案追究制自运行以来存在着许多问题,其所具有的负面影响超过了其积极效应的一面.本文从多角度分析了错案追究制产生的影响,并对错案进行了科学的界定.在此基础上,本文倡导错案追究制应让位于全面的司法改革,并提出了具体的司法改革措施.     

Robustness of a Class of Partial Diallel Cross Designs to the Unavailability of a Complete Block of Observations

Complete and partial diallel cross designs are examined as to their construction and robustness against the loss of a block of observations. A simple generalized inverse is found for the information matrix of the line effects, which allows evaluation of expressions for the variances of the line-effect differences with and without the missing block. A-efficiencies, based on average variances of the elementary contrasts of the line-effects, suggest that these designs are fairly robust. The loss of efficiency is generally less than 10%, but it is shown that specific comparisons might suffer a loss of efficiency of as much as 40%.     

评鲍德里亚的"消费社会理论"

鲍德里亚系统提出了"消费社会"的理论。他企图对唯物史观进行"颠覆"是错误的。但是不能简单地认为他是资本主义制度的辩护士。鲍德里亚不懂得马克思从根本上颠覆了国民经济学和唯心主义历史观的两种"幻象",从而奠定了生产和劳动对于人类社会存在与发展的基础性地位;不懂得消费与生产的现实辩证关系,片面地离开生产探讨消费的新特征,甚至主张用消费取代生产。消费异化是劳动异化的表现。技术救赎不可能解决当代人类面临的重大社会问题。     

试述台湾少年团在抗战中的宣传活动

1937年开始的抗日战争是中华民族抗击日本侵略的战争。大陆的中华儿女和海外炎黄子孙,包括广大的台港澳同胞都参加了抗战。他们当中,不仅有青壮年,还有老人和儿童。台湾少年团只是活跃在祖国抗日战场上的千万个儿童抗日团体之一,但其抗日活动有鲜明的特点。本文拟通过对台湾少年团在抗战中的宣传鼓动活动的考述,突出台湾少年为民族解放战争作出的贡献,再现其爱国精神和期盼祖国统一的心愿。     

5次交错群A_5的10阶子群的一个构造方法

A5的元最大阶数是5,使用有限群的Lagrange定理,A5的10阶子群元的阶只可能是2,5。但由于拉格朗日定理的逆不成立,因此是否存在A5的10阶子群仍是问题。该文通过对5-循环置换各次方幂的计算及其研究,找到A5的10阶子群元的构成规律,并使用构造性方法给出了5次交错群A5的6个10阶子群。     

一类非线性波动方程的新精确解

利用李群对称方法,通过构造变换不变量,将一类1 1维非线性波动方程化为常微分方程,得到了这一类非线性波动方程的一些新的显式精确解,包括孤子解、三角函数解和椭圆函数周期解。     

朱德与中共第一代领导集体的形成

朱德进入中共中央第一代领导集体 ,凭藉的是他的卓越的军事贡献和丰富的政治经验。从“红军之父”到“中国军人的伟大导师” ,从“人民的救星”到“党的领袖” ,既表明了他对党和人民事业的无限忠诚 ,也蕴含着党和人民给予他的极大光荣 ,反映了他追求进步 ,服从真理 ,实事求是 ,不断创新的卓越品质。第一代领导集体形成的标志时期是党的七大。朱德在第一代领导集体中的地位非常重要 ,他实际上起了一个稳定的中和的作用 ;从194 5年到 195 6年 ,朱德在中共中央和中央军委的职务、地位和威望仅次于毛泽东。     

科技创新是现代化高校发展的重要标志

近年来,高校作为国家科技创新体系的重要组成部分,大力加强科学研究。北京大学让本科生提前介入科研,培养科研创新能力。高校创办的具有特色的大学科技园、高科技产业群,逐步发展成为普遍趋势,高校已经成为中国基础研究的主力军。高校现有的人才资源有效结合起来,就形成一批充满活力的科技创新集体。     

The Chinese-speaking Muslims (Dungans) of Central Asia: A Case of Multiple Identities in a Changing Context

Chinese-speaking Muslims, called Dungans in Central Asia and Huizu in China, were forced to migrate to present-day Kazakhstan, Kyrgyzstan and Uzbekistan at the end of the nineteenth century. They reconstructed their identity through interrelations with local populations and the soviet categorisation of nationality. But after 1991, their status has being gradually destabilised owing to the changes in economic, social and political rules as well as citizenship regulations in these countries. They have to readapt to the new situation created by the independence of the three former Soviet Republics, which has challenged their unity.     

Fifteen Years of Family Group Conferencing: Coordinators Talk About Their Experiences in Aotearoa New Zealand

Family Group Conferencing (FGC) as a solution-focused strategyin child welfare has now been a mandated practice in AotearoaNew Zealand since 1989. This qualitative study examines theexperiences of Care and Protection Coordinators who have beenconvening FGC since the early years of the legislation. Thestudy explores early perceptions of the legislation, what firstattracted them to the role and what keeps them in the job. Inparticular, the study explores the practice tensions that restwithin family-centred child protection models, and the waysin which FGC practice has developed in response to modern imperatives.
