论中国山水画中的气韵

山水画中的"气韵"是作品艺术生命的关键。本文从"山泽通气"和"地气升而为云,天气降而为雨"方面阐述天地交感的气机升降出入问题,探讨画家怎样摄取大自然的气机并创作出气韵生动的画作,以及欣赏者怎样欣赏作品中的气韵,从而获得艺术审美享受。     

现行速动比率不能真实反映企业即时偿债能力

现行速动资产中很多是不能“速动”的 ,原因在于现行速动资产各项目内部的构成比较复杂。因此 ,应该对速动资产各项目进行科学的分类 ,以区分出哪些是真正的速动资产 ,哪些是并不能“速动”的速动资产 ,在此基础上确定出真正的能够“速动”的速动资产 ,从而计算出真正能够代表即时偿债能力的速动比率来。     

Statistical control charts for monitoring the mean of a stationary process

Recently statistical process control (SPC) methodologies have been developed to accommodate autocorrelated data. A primary method to deal with autocorrelated data is the use of residual charts. Although this methodology has the advantage that it can be applied to any autocorrelated data it needs time series modeling efforts. In addition for a X residual chart the detection capability is sometimes small compared to the X chart and EWMA chart. Zhang (1998) proposed the EWMAST chart which is constructed by charting the EWMA statistic for stationary processes to monitor the process mean. The performance of the EWMAST chart the X chart the X residual chart and other charts were compared in Zhang (1998). In this paper comparisons are made among the EWMAST chart the CUSUM residual chart and EWMA residual chart as well as the X residual chart and X chart via the average run length.     

顾恺之“传神论”美学思想探析

顾恺之是中国最早系统提出“传神论”的绘画美学理论家。“以形写神”、“迁想妙得”等理论成为中国人物画的重要创作方法。从“传神论”的哲学源头入手，讨论各家思想对其画论的影响，论述“传神写照”这一理论中“神”的内涵，重点从审美体验来论证“以形写神”、“迁想妙得”等概念，从而加深对顾恺之绘画理论的理解。     

An efficient method for the estimation of multivariate moving averge models

Durbin's (1959) efficient method for the estimation of univariate moving average models is generalized to the vector case. Strong consistency and asymptotic normality of the estimator is proved. A simulation experiment is performed to illustrate the behaviour of the method in finite samples.     

R2 Bounds for Predictive Models: What Univariate Properties Tell us About Multivariate Predictability

ABSTRACT

A long-standing puzzle in macroeconomic forecasting has been that a wide variety of multivariate models have struggled to out-predict univariate models consistently. We seek an explanation for this puzzle in terms of population properties. We derive bounds for the predictive R² of the true, but unknown, multivariate model from univariate ARMA parameters alone. These bounds can be quite tight, implying little forecasting gain even if we knew the true multivariate model. We illustrate using CPI inflation data. Supplementary materials for this article are available online.     

Should I Stay or Should I Go?

Abstract

Data from a longitudinal study of older adults in an upstate New York county (N = 333) show that poor housing “fit” increases the likelihood that older adults are currently considering a move, as does lower residential satisfaction. Those adults who said only that they “might consider moving” focused on health transitions that might signal a need for a new housing situation. Residential satisfaction predicts actual moves even when controlling for moving plans. Older adults may be “pushed” to make a move by a crisis, but those older adults planning moves tend to be “pulled” into housing arrangements with desirable features.     

运动电荷的库仑定律与电场

在讨论库仑定律时，一般注重分析静态形式，没有分析运动电荷的库仑定律与电场，本文针对此问题就运动电荷的库仑定律及电场进行分析与讨论。     

《感动中国》符码系统理论分析

约翰.菲斯克的符码系统理论可以把《感动中国》文本归结为三个层次的意义:直接意指分析、含蓄意指分析和意识形态分析。在意识形态层面上可以看出,《感动中国》对于受众现实主体的建构起着重要的作用,这也是为什么它代表着主流文化在众多节目中脱颖而出的原因。     

叶嘉莹“兴发感动”理论对王国维“境界”的 体系化及反思

港台词坛在20世纪80年代之前,研究上延续了晚清民初的词学本体传统,在对《人间词话》进行文本细读的过程中发现问题并彼此商榷和讨论,提出了许多值得探讨的问题。其中最值得关注的是对以"境界"为核心的诸概念的理解问题。在此研究背景中,叶嘉莹最大的贡献在于,当港台词坛对王国维的研究还停留在对个别概念的理解和论争上时,她已经有意识地运用"兴发感动"理论使"境界"体系化,并使其在动态系统中获得自身内涵。但叶嘉莹的"兴发感动"理论将"境界"的创作视野囿于词的生命感发力,没有体会到王国维在"境界"中熔铸的人文理想,最终还是与王国维的"境界"擦肩而过。
