Evaluation of CUSUM Charts for Finite-Horizon Processes

This article analyses and evaluates the properties of a CUSUM chart designed for monitoring the process mean in short production runs. Several statistical measures of performance that are appropriate when the process operates for a finite-time horizon are proposed. The methodology developed in this article can be used to evaluate the performance of the CUSUM scheme for any given set of chart parameters from both an economic and a statistical point of view, and thus, allows comparisons with various other charts.     

Testing Periodicity in Short Series and Application to Gene Expression Data

Testing for periodicity in microarray time series encounters the challenges of short series length, missing values and presence of non-Fourier frequencies. In this article, a test method for such series has been proposed. The method is completely simulation based and finds p-values for test of periodicity through fitting Pearson Type VI distribution. The simulation results compare and reveal the excellence of this method over Fisher's g test for varying series length, frequencies, and error variance. This approach is applied to Caulobacter crescentus cell cycle data in order to demonstrate the practical performance.

A Monte Carlo comparison of GMM and QMLE estimators for short dynamic panel data models with spatial errors

We suggest a generalized spatial system GMM (SGMM) estimation for short dynamic panel data models with spatial errors and fixed effects when n is large and T is fixed (usually small). Monte Carlo studies are conducted to evaluate the finite sample properties with the quasi-maximum likelihood estimation (QMLE). The results show that, QMLE, with a proper approximation for initial observation, performs better than SGMM in general cases. However, it performs poorly when spatial dependence is large. QMLE and SGMM perform better for different parameters when there is unknown heteroscedasticity in the disturbances and the data are highly persistent. Both estimates are not sensitive to the treatment of initial values. Estimation of the spatial autoregressive parameter is generally biased when either the data are highly persistent or spatial dependence is large. Choices of spatial weights matrices and the sign of spatial dependence do affect the performance of the estimates, especially in the case of the heteroscedastic disturbance. We also give empirical guidelines for the model.     

大学英语听说教学资源的开发与利用

语言输出理论认为语言习得过程应该是一个输入与输出的双向过程,二者结合才能提高学习者第二语的流利程度和准确性。在大学英语听说教学中恰当开发英美影视材料能够开辟一种学生熟悉的、更加多元、有趣有效的语言输入环境,激发学生英语认知资源的主动输出,形成听、说教学的良性循环和相互促进。将英美影视材料合理融入教学是培养学生的英语综合应用能力尤其是听说能力,达到教学目标的有益尝试。     

劳伦斯短篇小说的阶层意识及认同危机

阶层意识和阶层认同危机在劳伦斯的很多作品中都有直接的体现。文章试图以较少论及的劳伦斯短篇小说为主要文本解读对象,分析这一认同危机在文本中显示的过程,结合劳伦斯与布鲁姆斯伯里文化圈的个人交往进一步论述该问题。     

多元智能理论与英语影视教学整合初探

本文探讨了霍华德.加德纳的多元智力理论与英语影视教学整合的可能性和必要性,以及两者在整合实践中需遵循的原则和实际操作方式,目的在于改进英语影视教学形式,系统全面地开发学生的多种智能,促进教学质量与学生综合素质的提高.     

“隋唐燕乐”的不同系统与词的起源

词的产生受"隋唐燕乐"的影响,研究词起源不得不对"隋唐燕乐"进行考察.词的起源与词体的正式确立应视为两个概念.词的起源与音乐的关系最为密切,应主要关注词如何由音乐生成;词体的正式则为文体学的问题,重点在于区别词是如何独立成为一种文体.有唐一代并无"隋唐燕乐"的概念,是后人为了称谓及研究的方便而提出的."隋唐燕乐"包罗万象,主要有两大系统:一为宫廷音乐系统,一为民间音乐系统.二者各自对词的形成产生不同的影响.词体雏形孕育于民间,词起源的时间,其上限只能是初唐,下限只能是盛唐,词体的正式成立在中晚唐.
