学生语言学习的错误主要有两类操作性错误即语法错误与交际性错误,对于一般性语法错误,不要纠正过多.对于交际性错误要给予重视,要注意加强社会文化教育. 相似文献

中国在进行廉政建设的同时,也在进行政府效能监察工作。效能监察是监察机关为维护公共利益对监察对象存在的不尽职、不正确尽职、影响其他人尽职,乃至玩忽职守渎职失职等违法、违纪行为进行的监督检查活动。由于理论支撑滞后和相对经验不足,至今没有形成公众认可的、在较大范围适用的政府效能监察体系。本文依据调查资料,分析了构建当代政府效能监察体系的实践基础,揭示了政府效能监察体系的内容结构,预测了政府效能监察的发展趋势,提出了健全和完善效能监察体系的措施。 相似文献

交际失误现象在非正式交际中是不可避免的,在本质上属于生动的、自发的交流。到目前为止,语言学文献中很少讨论言语相互作用而导致的交际不顺畅,以及不成功交际中产生的交流失误。现代语言学对交际失误的系统研究刚刚开始。引起交际失误的语言学因素包括编码错误和评价行为特征,对交际失误产生的原因进行研究,很有必要。 相似文献

ABSTRACTThe purpose of this paper is to prove, under mild conditions, the asymptotic normality of the rank estimator of the slope parameter of a simple linear regression model with stationary associated errors. This result follows from a uniform linearity property for linear rank statistics that we establish under general conditions on the dependence of the errors. We prove also a tightness criterion for weighted empirical process constructed from associated triangular arrays. This criterion is needed for the proofs which are based on that of Koul [Behavior of robust estimators in the regression model with dependent errors. Ann Stat. 1977;5(4):681–699] and of Louhichi [Louhichi S. Weak convergence for empirical processes of associated sequences. Ann Inst Henri Poincaré Probabilités Statist. 2000;36(5):547–567]. 相似文献

The forecasting of sales in a company is one of the crucial challenges that must be faced. Nowadays, there is a large spectrum of methods that enable making reliable forecasts. However, sometimes the nature of time series excludes many well-known and widely used forecasting methods (e.g., econometric models). Therefore, the authors decided to forecast on the basis of a seasonally adjusted median of selected probability distributions. The obtained forecasts were verified by means of distributions of the Theil U2 coefficient and unbiasedness coefficient. 相似文献

We present a framework to describe and analyze operational risk in financial services from an operations management perspective, focusing in particular on process design, process management, and human behavior aspects. The financial services industry differs from other service industries in ways that affect the nature of the operational risks it is subject to. In recent decades, many books and papers have focused on operational risk in financial services; however, this literature has focused mainly on the conceptual and statistical aspects of operational risk management and not on its operational aspects. Operational risk in financial services has not received much attention from the operations management community. The framework presented here is based on the premise that operational risk in financial services can reap significant benefits from research done in the theory and practice of operations management in manufacturing industries as well as in other services industries. The objective of this study is to propose particular challenges and questions raised in the practice of operational risk management that may stimulate future research in this particular area of operations management. 相似文献

为了获得情报,肃清内奸,加强宣传,反制敌方邮检,苏区实行了邮检制度。邮检对象包括:密写、密函信件,记录有军政情报内容的胶卷、录音带、录像带、报刊杂志,夹藏有显微点以及炸弹、毒品、恐吓信、内容反动的信件或者出版物。邮检方式主要有四种。对受检邮件的处理方式有三种。总之,苏区对邮检极为重视,除严格选拔邮检员外,还制定了纪律,操作也较规范。 相似文献

We derive an exact F-test for random effects in the nested-error regression model. The derivation utilizes a matrix decomposition that offers a transformation of the response vector into two independent subvectors. When the random effects are absent, the test statistic reduces to a ratio of two independent residual sums of squares that are computed by fitting a regression model using each subvector. A small simulation study compares the power of the F-test with various recent tests and shows that the proposed test has a competitive performance under small as well as large number of clusters. 相似文献

Homogeneity of variance is a basic assumption in longitudinal data analysis. However, the assumption is not necessarily appropriate. In this paper, Fisher scoring method is applied to get M-estimator in the exponential correlation mixed-effects linear model. The score tests for heteroscedasticity and correlation coefficient based on M-estimator are then studied. Monte Carlo method is applied to investigate the properties of test statistics. At last, the methods and properties are illustrated by an actual data example. 相似文献
