中国古代诉讼当事人的主体地位与诉权

中国古代社会是一个"权力本位"的社会,没有明确的权利概念,但并不能由此推论出中国古代法律就不保障权利。就诉讼而言,中国古代诉讼当事人绝非客体,而具有一定的主体地位,并享有多方面的诉权,只是相对于现代人来讲,其主体地位和诉权均不够充分。     

艺术的身体性本源——从身体出发解读尼采美学

尼采文本中隐含着一条思想的道路,即从身体出发,在身体敞开的维度内思考问题。身体为我们透视尼采的美学提供了这样一个视角:尼采是从艺术家这一身体性的存在者出发思考艺术的本源,他在艺术家的陶醉状态中揭示出作为创造力意志的权力意志。权力意志作为艺术的本源是身体性的,具体表现为人类学、生理学和心理学三个方面。     

晚清督抚制度与权力制衡

清朝统治者继承并改善了督抚制度，建立了一套较为完善的权力体系，使中央与地方之间保持了200多年的制衡状态。19世纪中叶，由于战争的原因，这种平衡被打破。太平天国运动的爆发，晚清地方督抚彻底掌握了交战各省的军政大权，政令、军令得以统一。这一方面为清朝在战争中获得胜利奠定了基础，另一方面也造成了中央与地方权力的失衡。     

音乐情绪感知的脑电研究

利用情绪量表筛选出对应愉快、快乐、悲伤、恐惧四种情绪的音乐片段作为刺激,同步记录脑电,从脑区、情绪极性、强度等方面对脑电α波功率的变化进行了分析。结果表明:脑电α波功率的变化与情绪的极性和强度密切相关;快乐与恐惧、愉快与恐惧、恐惧与悲伤之间α波功率差异显著;顶枕区α波功率在负极性情绪中强度强的明显小于强度弱的;在强度强的情绪中,正极性情绪显著大于负极性情绪。     

A BETA-OPTIMAL TEST OF THE EQUICORRELATION COEFFICIENT

This paper considers the problem of testing for nonzero values of the equicorrelation coefficient of a standard symmetric multivariate normal distribution. Recently, SenGupta (1987) proposed a locally best test. We construct a beta-optimal test and present selected one and five percent critical values. An empirical power comparison of SenGupta's test with two versions of the beta-optimal test and the power envelope shows the relative strengths of the three tests. It also allows us to assess and confirm Efron's (1975) rule of when to question the use of a locally best test, at least for this testing problem. On the basis of these results, we argue that the two beta-optimal tests can be considered as approximately uniformly most powerful tests, at least at the five percent significance level.     

On Robust Analysis of a Normal Location Parameter

Pericchi and Smith considered a normal location parameter problem with double-exponential and Student t prior distributions. These two prior distributions both belong to the class of scale mixtures of normal distributions and are useful in providing a robust analysis of the normal location parameter problem. In this paper we extend the analysis to other scale mixtures of normal distributions, such as the exponential power and the symmetric stable distributions.

论大学学术权力的合法性

将合法性理论运用于大学学术权力分析,探讨大学学术权力合法性问题,其根本目的在于破解大学学术秩序"何以可能"及"何以持久"的问题,是探索存在于大学之中的学术权力是否具有合法性,凭借何物得以合法存在,凭借什么获得学术组织成员的集体认同。通过该问题的研究探讨,对于我们深入理解大学学术组织内部权力构造与组织发展模式,加快世界一流大学建设具有重要的理论意义和现实价值。     

THE POWER OF STUDENT'S t TEST: CAN A NON-SIMILAR TEST DO BETTER?

Lehmann & Stein (1948) proved the existence of non-similar tests which can be more powerful than best similar tests. They used Student's problem of testing for a non-zero mean given a random sample from the normal distribution with unknown variance as an example. This raises the question: should we use a non-similar test instead of Student's t test? Questions like this can be answered by comparing the power of the test with the power envelope. This paper discusses the difficulties involved in computing power envelopes. It reports an empirical comparison of the power of the t test and the power envelope and finds that the two are almost identical especially for sample sizes greater than 20. These findings suggest that, as well as being uniformly most powerful (UMP) within the class of similar tests, Student's t test is approximately UMP within the class of all tests. For practical purposes it might also be regarded as UMP when moderate or large sample sizes are involved.
