南宋古文评点缘起发覆--兼论古文评点的文章学意义

始于北宋末的科举策论、经义的程式化,是南宋评点兴起的历史契机,而诗赋程式、"江西诗派"诗文论则是评点家的参照模式和评论方法.南宋的古文评点有着重要的文章学意义,它所揭示的文章技法的精华部分,就是在今天也不过时.     

英文易读度测量程序开发探索

英文易读度指英语文本易于阅读和理解的程度或性质,是应用语言学的重要概念.正确地测量易读度一直是研究者努力的目标.作者通过将应用语言学知识和计算机软件知识相结合,开发了一套适于我国大学英语教学的易读度测量程序-ERMS.以Flesch Reading Ease为计算公式,以CET-4和CET-6词汇为基础建立词库,并且能测量词汇密度使ERMS成为准确方便地测量英文易读度工具.     

On A strongly consistent nonparametric density estimator for the deconvolution problem

The problem of nonparametric estimation of a probability density function is studied when the sample observations are contaminated with random noise. Previous authors have proposed estimators which use kernel density and deconvolution techniques. The appearance and properties of the previously proposed estimators are affected by constants M_n and h_n which the user may choose. However, the optimal choices of these constants depend on the sample size n, the noise distribution and the unknown distribution which is being estimated. Hence, in practice, M_n and h_n are optimally selected as functions of the data. In this paper it is shown that a class of the proposed estimators are uniformly, strongly consistent when M_n and h_n are allowed to be random variables. Even when M_n and h_n are constants, these results are new findings.     

A note on Stein's lemma for multivariate elliptical distributions

When two random variables are bivariate normally distributed Stein's original lemma allows to conveniently express the covariance of the first variable with a function of the second. Landsman and Neslehova (2008) extend this seminal result to the family of multivariate elliptical distributions. In this paper we use the technique of conditioning to provide a more elegant proof for their result. In doing so, we also present a new proof for the classical linear regression result that holds for the elliptical family.     

On Confidence Intervals for Process Capability Indices in a One-Way Random Model

In this article, we investigated the bootstrap calibrated generalized confidence limits for process capability indices C _pk for the one-way random effect model. Also, we derived Bissell's approximation formula for the lower confidence limit using Satterthwaite's method and calculated its coverage probabilities and expected values. Then we compared it with standard bootstrap (SB) method and generalized confidence interval method. The simulation results indicate that the confidence limit obtained offers satisfactory coverage probabilities. The proposed method is illustrated with the help of simulation studies and data sets.     

从三鹿奶粉事件看诚信与成功

诚信是现代市场经济运行中一种重要的新的资本形态,是一个企业精神财富和生命所在。不守“诚信”,或许可“赢一时之利”,但一定会“失长久之利”。无诚信就无成功。财富品质的核心是诚信,诚信立业,诚信致富。诚信乃做人之根本,有诚信才有成功。     

中国供应链金融指数编制(下篇):指标体系构建、测算与结果分析

提出了中国供应链金融指数体系的具体指标及计算公式,其中,价格与风险指数体系包括价格指数、风险指数和夏普指数;规模与信用指数体系包括融资物金额规模指数及企业规模指数、核心企业信用指数和质押率指数。价格与风险指数的测算结果表明,2018年1月到6月供应链金融市场比较平稳,而7、8月则出现了较大的风险。规模与风险指数的计算结果显示2018年1月至6月,企业数量规模与融资物金额规模都急剧上升。通过对整个指数体系计算结果的分析,进一步验证了供应链金融是解决中小企业融资难、融资贵的有效途径,并能起到较好的预测经济发展的作用,但供应链金融市场还需要进一步规范和完善。     

论《琶杰格斯尔传》之马匹的程式

《琶杰格斯尔传》不仅是科尔沁口头文学的经典,也是蒙古族口传史诗的代表性文本。歌手琶杰遵循口头诗歌叙事传统,运用丰富的程式演唱不同的主题,构筑了格斯尔史诗诗行,使史诗故事跌宕起伏,变幻莫测,而且歌手运用的程式体现了其创编技巧,也显示了口头诗歌的表演法则。     

灰色Verhulst模型的灰导数改进研究

针对灰色Verhulst模型灰导数白化的问题,以白化微分方程为基础,运用梯形公式来白化灰导数,推导得到一种新的Verhulst模型定义式。该方法使得差分方程的参数与其在微分方程中对应的参数具有更好的一致性。实例分析表明改进的灰色Verhulst模型具有更高的预测和模拟精度。
