A decomposition technique for quantifying real process performance

A decomposition technique for quantifying the impacts of changes in product mix and process performance on aggregate process-related indicators is presented. Through application of the technique, the real performance of a process can be quantified. Changes in real performance over time can be monitored to provide useful information for process evaluation and production planning. Two case studies, one related to the aggregate defective rate for an assembly line of an integrated circuit fabrication plant and the other to the aggregate inventory turnover for a tyre distribution company, are presented to illustrate the application of the technique.     

Book Reviews

This article examines some difficulties associated with the Haynes–Stone model and attempts to clarify how the model can be justified as representing the hypothesis that “quantity is demand determined and price is supply determined.” It also argues that the applications of such a model as was done by Haynes and Stone might not have resolved the controversies related to the Phillips curve and the supply function of exports (or imports).     

Recursive location and scale estimators

It is shown that a recursive estimator with the same asymptotic properties as the median has convergence properties in finite samples which depend heavily on the scale of the data. A simple modification which adjusts for the scale is suggested and its application illustrated on simulated data. The modified estimator has much improved properties which are similar to those of the sample (non-recursive) median.     

THE BEHAVIOR OF HEGY TESTS FOR QUARTERLY TIME SERIES WITH SEASONAL MEAN SHIFTS

ABSTRACT

This paper studies the behavior of the HEGY statistics for quarterly data, for seasonal autoregressive unit roots, when the analyzed time series is deterministic seasonal stationary but exhibits a change in the seasonal pattern. We analyze also the HEGY test for the nonseasonal unit root. the data generation process being trend stationary too. Our results show that when the break magnitudes are finite, the HEGY test statistics are not asymptotically biased toward the nonrejection of the seasonal and nonseasonal unit root hypotheses. However, the finite sample power properties may be substantially affected, the behavior of the tests depending on the type of the break.     

结构性差异视角下的话语分析

有的学者把东西方文化之间对话存在障碍的主要原因归结为东西方之间的思想传统的结构性差异。中国人的思想具有互系性和通变的特点，而西方人秉持二元对应的思维传统。结构性差异视角下的话语分析可以在词汇、小句和价值观念三个层面上进行。实例分析验证了结构性差异是真实存在的，可使读者对所选语话材料有更加深刻细致的理解。

试析广告标题中谚语的变异

标题是广告的主题和灵魂。广告学者在活的标题语言实践中,有时会有意识地违反谚语内部的语言规律,故意偏离常规而选择特殊性的表达方式,变异谚语。本文试图从现代俄罗斯报纸广告的最新资料去分析、探讨俄罗斯广告作品创意者是如何巧妙地使用俄罗斯谚语作为广告标题的。     

Internal labor markets and the effects of structural change: Job mobility in Korean labor markets between 1998 and 2000

This study examines job mobility in Korean labor markets since the 1997 economic crisis. The rising job mobility in Korea is analyzed by focusing on structural change in labor markets. Using the Korean Labor and Income Panel Study and discrete-time event history analysis, I estimate the job-stabilizing effects of internal labor markets and the effects of structural change on job mobility. The major findings are as follows: First, I found that internal labor markets were weakening between 1998 and 2000. Second, the job-stabilizing effects of internal labor markets on job mobility diminished between 1998 and 2000. Finally, the magnitude of the effects of internal labor markets on job mobility was contingent on the level of structural change. The effect of internal labor markets on job mobility was stronger in turbulent or contracting industries. This effect, however, also became weaker over time. The implications for Korean labor markets are discussed.     

论元散曲中屈原评价的文化意义

元人对屈原基本上都是持一种嘲讽的态度。这种价值评判的形成 ,与元人的生存环境有着非常直接的关系。价值向度的变形来自于生存环境的险恶。同时 ,与历史上对屈原的消极评价也不无关联     

一类接续性拷贝式及其相关格式的语用考察

一类接续性拷贝式"A是A,B是B"格式(以下简称"是"格式)是一类评价性很强的固定格式,其基本格式义在世界很多语言中都存在,而汉语中的"是"格式,除了基本格式义以外,还能在更大的语篇中发生格式的语义偏移.根据该格式突出的语义色彩,可将其分为中性"是"格式(基本格式)和褒义"是"格式(偏移后的格式)两类,后者是前者在一定语境下发生语义偏移后得到的汉语特有的语义类型.
