中国古代调解制度探析

古代社会解决纠纷的途径多种多样,调解作为其中一种主要方式有着举足轻重的作用。在介绍中国传统调解制度的类型及特点的基础上,探讨传统调解制度对于古代封建社会的价值所在,认为其虽然存在一定的缺点,但是其有益的部分对我国当前的纠纷解决机制的完善有很大的借鉴作用。     

河道冰体的可爆性研究

冰是一种特殊的固体介质,具有非均匀性、各向异性、应变速率及温度敏感性等特点。本文以黄河爆炸破冰为背景,针对-10℃冰体结构与物理力学性能进行检测,以及冰体在不同加载条件下,所表现的响应特征与破坏特征进行了试验研究。通过分析冰晶体结构与冰内气泡特征,冰体在静载条件下的塑性破坏特征,以及对冰体对爆炸冲击载荷的响应特征,获得冰体的可爆性能与破碎单位体积冰体所需炸药能量计算公式。研究成果可为黄河冰体爆破作业提供理论依据。     

Point Estimates of Test Sensitivity and Specificity from Sample Means and Variances

In a wide variety of biomedical and clinical research studies, sample statistics from diagnostic marker measurements are presented as a means of distinguishing between two populations, such as with and without disease. Intuitively, a larger difference between the mean values of a marker for the two populations, and a smaller spread of values within each population, should lead to more reliable classification rules based on this marker. We formalize this intuitive notion by deriving practical, new, closed-form expressions for the sensitivity and specificity of three different discriminant tests defined in terms of the sample means and standard deviations of diagnostic marker measurements. The three discriminant tests evaluated are based, respectively, on the Euclidean distance and the Mahalanobis distance between means, and a likelihood ratio analysis. Expressions for the effects of measurement error are also presented. Our final expressions assume that the diagnostic markers follow independent normal distributions for the two populations, although it will be clear that other known distributions may be similarly analyzed. We then discuss applications drawn from the medical literature, although the formalism is clearly not restricted to that application.     

A new stratified three-stage unrelated randomized response model for estimating a rare sensitive attribute based on the Poisson distribution

This article suggests an efficient method of estimating a rare sensitive attribute which is assumed following Poisson distribution by using three-stage unrelated randomized response model instead of the Land et al. model (2011 Land, M., S. Singh, and S. A. Sedory. 2011. Estimation of a rare sensitive attribute using poisson distribution. Statistics 46 (3):351–60. doi:10.1080/02331888.2010.524300.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) when the population consists of some different sized clusters and clusters selected by probability proportional to size(:pps) sampling. A rare sensitive parameter is estimated by using pps sampling and equal probability two-stage sampling when the parameter of a rare unrelated attribute is assumed to be known and unknown.

We extend this method to the case of stratified population by applying stratified pps sampling and stratified equal probability two-stage sampling. An empirical study is carried out to show the efficiency of the two proposed methods when the parameter of a rare unrelated attribute is assumed to be known and unknown.     

论《镜花缘》中科幻小说之特色

清代长篇小说《镜花缘》的内容丰富多彩,其类属和特点也比较多样。鲁迅说它属博物小说,才艺小说;胡适称它为妇女问题小说,女权小说,等等。此外,小说还描写了一些精彩的科幻故事,包括科幻植物如人吃一颗饱一年的巨米,人吃了能蹿高的蹑空草,长效久饱干粮救荒豆末;包括科幻器物如人穿上能长时间潜水的皮衣皮裤,能连续高速开火的火绳枪—连珠枪,能载人载货飞行的飞车;包括科幻技术,如人能近地但不触地地行进,换心补肺的医术。文章从科学、文学、历史几方面对上述科幻故事进行了考察、解读、诠释、分析、评论,研究总结出：《镜花缘》也具科幻小说之属性和特点,是我国第一部也进行了科学幻想文学创作的长篇小说。     

Bayesian estimation of rare sensitive attribute

Randomized response models have been used to estimate a population proportion of a sensitive attribute. A randomized device is typically employed to protect respondent's privacy in a survey. In addition, an unrelated question is asked to improve the statistical efficiency. In this article, we propose Bayesian estimation of rare sensitive attribute using randomized response technique, which includes a rare unrelated attribute. Two cases are considered, the proportion of a rare unrelated attribute is known and unknown. A simulation study is conducted to assess the performance of the models using mean absolute error and coverage probability. The results show that the performance depends on the parameters and is robust to priors.     

残疾人创业的信任环境重构——基于团队特征的视角

论纯情节类RPG的审美构成——以国产经典RPG为例

近些年随着电子游戏的发展,游戏艺术的文学性日益突出,尤其是纯情节类RPG游戏,其文学性主要体现在三个方面:情节是游戏文学性和艺术性的主体部分,也是玩家最不能脱离的游戏基因。游戏画面和背景配音起辅助作用。游戏的世界观构成了玩家对待RPG的基本审美态度,是游戏审美的核心元素。     

“十七年”音乐创作与社会的互动研究

十七年音乐在新中国音乐发展史上属于“特例”,既非建国前的“十里洋场”,亦非文革时代的“高快硬响”。音乐创作对传统的“爱情”主题进行了重新阐释与定位,将其放置到革命或者建设社会主义的大语境下来论述,使爱情叙事打上了鲜明的政治烙印。但创作者并非完全听从政治指令的艺术木偶,他是以一种更为隐性的方式将创作的触角伸向少数民族题材的音乐,以此寻求“宏大叙事”与“个人情感”之间的平衡。创作出了明显区别于其他时代的爱情歌曲,具有特别的审美价值。
