以书入画、书写性用笔是中国画"用笔"方面的一个重要体现,也是中国画区别于其他绘画画种的本质特征。古往今来,中国画对于用笔的尝试与表述经历了一个较长的探索历程,文章从线的角度入手,对中国画中笔法的成长历程作了较为深入的分析和阐述。 相似文献

In this article, the block maxima (BM) and the peak over threshold (POT) methods are used to model the air pollution. A simulation technique is suggested to choose a suitable threshold value. The validity of the estimated models is checked by the Kolmogorov–Smirnov (K-S) test. A new efficient approach for modeling extreme values is suggested. Finally, the inconsistency and weak consistency of bootstrapping central and intermediate order statistics for an appropriate choice of re-sample size are investigated. 相似文献

杜威将人的能力形成归为人的心智功能,米德将心智功能看作人使用符号的结果,由此创建了符号互动论学派。文章将米德的互动分析方法设计为一种结构图,同时使用帕森斯有关行动的雄制图式,设计了互动的体制图式,运用互动的结构图和体制图式建构了分析技术的方法论图式,从符号的视角,揭示技术的秩序、组织、制度本质。技术是人类借用文化符号发展起来的利用自然的特殊符号体系,是内含许多人类信息符号的物化存在。 相似文献

司法改革是世界各国面临的共同性问题。立足于现行宪政体制,以维护社会整体利益为价值目标,是我国司法改革的务实思路。就我国目前而言,司法改革,除了内在体制、理念的变革外,也包括外在形式的各种符号性变化。“法官职业化”凸显了司法改革对“人的因素”的关注,它与司法外部构造上的“非地方化”和内部管理上的“非行政化”一起构成了目前和今后我国司法改革的方向。程序是司法之特殊所在,故司法程序改革应当是司法改革的基础性问题。司法改革的理想是实现现代司法理念引领下的公平与正义,追求司法权的独立,然而这一目标的实现必然是一个渐进的漫长过程。 相似文献

An optimum unbiased estimator of the variance of mean is given It is defined as a function of the mean and itscustomary unbiased variance estimator, utilizing known coefficient of variation, skewness and kurtosis of the underlying distributions. Exact results are obtained. Normal and large sample cases receive particular treatment. The proposed variance estimator is generally more efficient than the customary variance estimator; its relative efficiency becomes appreciably higher for smaller coefficient of variation, smaller sample (in the normal case at least), higher negative skewness, or higher positive skewness with sufficiently large kurtosis. The empirical findings are reassuring and supportive. 相似文献

Violation of respondent's privacy in moors* model- its rectification through a random group strategy
The primary objective of the randomized response techniques introduced by Warner (1965) and Greenberg et al. (1969) was to protect the privacy of the respondents while eliciting information on sensitive issues. However, Moors' (1971) model, which is considered to be the best in the sense of optimality and convenience to use, fails to protect the privacy of respondents in certain cases. The present paper aims at pointing out this serious draw back. An alternative model termed as 'random group method ' is proposed. The proposed model is free from the above mentioned drawback and provides more efficient estimator as compared to the usual Greenberg at al. 's (1969) model. 相似文献

Quarterly real GNP and implicit GNP deflator series are derived for the 1948–1970 period using the related series technique of Chow and Lin. These estimated series are compared with the official, revised series; to official, unrevised series; and to univariate proxies using regression, time series, and spectral methods. The derived series possess autocorrelation and turning point characteristics similar to those of the official, revised series. The derived series also deliver structural equation parameter estimates similar to those based on official, revised data. 相似文献

This paper seeks to contribute to the sociology of nations, a literature that is only starting to carve out its place in the social sciences. The paper offers a reconceptualization of “nations” as “national cultures”, employing an evolutionary perspective and a systemic framework in which “nations” are understood as cultural systems of a special kind. National cultures are intimately tied to natural languages, and the acquisition of a national culture occurs as part and parcel of the acquisition of a natural language. Acquiring a natural language is a prerequisite for learning other cultural systems (artefactual languages as well as other natural languages). National cultures function as metacultures. They are also the reference cultures for modern states and their citizens, a political dimension of nations that is of paramount importance, though it will only be touched on in this paper. National cultures should be considered as the most fundamental type of cultural system today. 相似文献
