Multivariate process capability a bayesian perspective

In this paper an attempt has been made to examine the multivariate versions of the common process capability indices (PCI's) denoted by C_p and C_pk . Markov chain Monte Carlo (MCMC) methods are used to generate sampling distributions for the various PCI's from where inference is performed. Some Bayesian model checking techniques are developed and implemented to examine how well our model fits the data. Finally the methods are exemplified on a historical aircraft data set collected by the Pratt and Whitney Company.     

Linex discrepancy for bandwidth selection

A bandwidth selection based on Linex discrepancy is proposed for kernel smoothing of periodogram. The selection minimizes Linex discrepancy between the smoothed and true spectrums. Two estimators are introduced for Linex discrepancy. The bandwidth choice outperforms some common bandwidth choices.     

GMC/GEL estimation of stochastic volatility models

In this article we discuss the estimation of stochastic volatility (SV) using generalized empirical likelihood/minimum contrast methods based on moment conditionsmodels. We show via Monte Carlo simulations that the proposed methods have superior or equivalent performance to the other alternative methods, and, additionally, they offer robustness properties in the presence of heavy-tailed distributions and outliers.     

中美文化差异探源

中美文化差异较大。中国人的认知以情境为中心,美国人则以个人为中心;中国人以被动的态度看待世界,美国人以主动的态度征服世界。中国人具有群体意识和中和意识,美国人具有个体意识和竞争意识;中国人喜欢中庸性,美国人强调排中性;中国人的思维方式体现在辩证思维上,美国人的思维方式体现在逻辑思维或分析思维上。从自然环境、劳动方式、民族历史、传统思想、社会认知以及文字构成等方面来探寻中美文化差异的渊源。     

论行政责任与民事责任的严格区分——以现行交通事故相关处理规定为例

行政责任是指违反国家行政法规所规定的行政义务或法律禁止事项而应承担的法律责任.其特征是:(一)行政责任以行政义务的存在为前提;(二)行政责任是违反行政义务的行为人应承担的法律责任;(三)行政责任种类呈多样化形式.民事责任是民事主体违反民事义务所应承担的法律后果,它是法律责任中一种独立的责任.其特征是:(一)民事责任以民事义务的存在为前提;(二)民事责任是违反民事义务的行为人应承担的法律责任;(三)民事责任主要是财产责任.严格区分行政责任和民事责任是促使立法质量"与时俱进"的重要因素之一.     

On the Correspondence Between Physiological and Nonverbal Responses: Nonverbal Behavior Accompanying Challenge and Threat

Little is known regarding the covariance between physiological and nonverbal responses to “stressful” situations. We argue that physiological markers are especially likely to be accompanied by psychologically-meaningful nonverbal behavior. Within “stressful” motivated performance situations, complex patterns of cardiovascular (CV) reactivity mark challenge and threat motivational states relevant to confidence. We expected the CV challenge and threat markers to be distinguished on the basis of facial and vocal confidence. In a test of this hypothesis, participants’ cardiovascular (CV) responses were recorded during a videotaped social interaction. As expected, the CV challenge marker was associated with more vocal confidence and less facial confidence than the CV threat marker. These findings are related to the complexity of human responses to motivated performances.     

赵树理的农村书写及其文学命运

20世纪中国文学以乡土之外的观念对农村和农民进行文学想象和叙述,它造成了真实农村图景的遮蔽和放逐,而赵树理的创作是个例外。他既是知识分子又不完全认同“五四”知识分子的话语体系,既倾向于农民的价值观又不是纯然的农民。他的农村书写与农民、革命意识形态之间一度形成良性互动,故其作品被奉为文学经典。后来因他执著的写实立场与当代文艺规范发生摩擦而产生裂隙,最终导致其文学命运的坎坷。

钱钟书与林语堂散文的幽默品格及其文本差异

20世纪三四十年代同时提倡幽默文风的文学大家钱钟书与林语堂,其幽默品格各有特色,前者重“理”,深得西方随笔的理趣,充满了学者式的思辨与博弈;后者重“情”,即情调,情趣,是对中国古典散文精神的继承,追求士大夫的闲适与雅趣,这与晚明“性灵文学”的渊源一脉相承。他们横移与纵向继承所形成的不同幽默风格及其文本差异,丰富了现代散文的内涵,对散文审美体系的建立产生了重要影响。
