谈"中国情境"下的波谱艺术

艺术总是摆脱不了时代的制约,波谱艺术也是如此。这个在西方市场经济和消费文化的语境下产生的艺术形式,当它登陆中国大陆时,由于其生存的土壤发生了变化,因此,也在中国的土地上勾勒出了一条有着"中国特色"的发展轨迹。

形成性评估与大学生课外英语自主学习

大学生具有较强的课外英语自主学习意识,但并未都转化为相应的课外英语自主学习行为。高质量的形成性评估可以促进大学生课外自主学习意识向自主学习行为的迁徙,提高大学生的英语自主学习能力。     

理工科大学素质教育中的中国民族音乐教育

艺术素质教育在古往今来的教育中都承担着重要的角色。中国民族音乐作为集艺术性与民族性为一体的音乐艺术形式,在世界音乐艺术领域占有重要的地位。通过不同的艺术教育途径,发扬和传承中国民族音乐,让更多的理工科大学生了解和热爱中国民族音乐,提高自身音乐修养,最终达到专业与艺术的完美融合。     

《解放日报》视域中的延安时期男女婚恋观的嬗变及其影响

1942年4月1日《解放日报》将“文艺”专刊改为综合性副刊。《解放日报》改版前的作品更多地是呈现知识分子对于自由婚恋的憧憬与理想,探讨婚后女性面临家庭与事业难以兼顾的窘境以及个人私欲与革命信仰进行博弈而产生的离婚危机。改版后,综合副刊上刊登的婚恋作品主人公大多是工农兵出身,呈现出政治进步可以成就美满婚姻、夫妻共同参加生产劳动可以促进家庭和谐、男女努力学习知识就可以收获爱的体验的新型婚恋观。文章通过考察改版前后不同时期《解放日报》上发表的涉及婚恋问题的文学作品,发现了延安时期男女婚恋观念的嬗变轨迹,认为《解放日报》对男女婚恋问题的反映与思考,对建国后“十七年文学”有着深刻的影响与启示。     

STEIN'S METHOD AND THE BERRY-ESSÉEN THEOREM

Stein's method is used to prove the Lindeberg-Feller theorem and a generalization of the Berry-Esséen theorem. The arguments involve only manipulation of probability inequalities, and form an attractive alternative to the less direct Fourier-analytic methods which are traditionally employed.     

A robust multivariate measurement error model with skew-normal/independent distributions and Bayesian MCMC implementation

Skew-normal/independent distributions are a class of asymmetric thick-tailed distributions that include the skew-normal distribution as a special case. In this paper, we explore the use of Markov Chain Monte Carlo (MCMC) methods to develop a Bayesian analysis in multivariate measurement errors models. We propose the use of skew-normal/independent distributions to model the unobserved value of the covariates (latent variable) and symmetric normal/independent distributions for the random errors term, providing an appealing robust alternative to the usual symmetric process in multivariate measurement errors models. Among the distributions that belong to this class of distributions, we examine univariate and multivariate versions of the skew-normal, skew-t, skew-slash and skew-contaminated normal distributions. The results and methods are applied to a real data set.     

Moment‐Independent Sensitivity Analysis Using Copula

In risk assessment, the moment‐independent sensitivity analysis (SA) technique for reducing the model uncertainty has attracted a great deal of attention from analysts and practitioners. It aims at measuring the relative importance of an individual input, or a set of inputs, in determining the uncertainty of model output by looking at the entire distribution range of model output. In this article, along the lines of Plischke et al., we point out that the original moment‐independent SA index (also called delta index) can also be interpreted as the dependence measure between model output and input variables, and introduce another moment‐independent SA index (called extended delta index) based on copula. Then, nonparametric methods for estimating the delta and extended delta indices are proposed. Both methods need only a set of samples to compute all the indices; thus, they conquer the problem of the “curse of dimensionality.” At last, an analytical test example, a risk assessment model, and the levelE model are employed for comparing the delta and the extended delta indices and testing the two calculation methods. Results show that the delta and the extended delta indices produce the same importance ranking in these three test examples. It is also shown that these two proposed calculation methods dramatically reduce the computational burden.     

生命信息的交融互渗——中国花鸟画审美初探

自然界的有生命之物,以其不同的形状、色彩、气息和动静之态,而有着不同的审美价值.它们的美是生命之美.中国花鸟画不以再现自然对象的外形为目的,而以思想、情感、意趣等生命现象的高级形式反映在作品中.作者根据主观的审美理想和自我生命的节律加以重新创造,使其固定为物化状态,给人以美的滋养.
