浅谈英语强调句式的常用手段

当代英语中,强调句式的强调手段各种各样。本文将众多的强调手段归纳为语音,词汇和语法这三个主要类别。这样的分类使英语强调句式的教学清晰、简洁,更具有实用性。     

浅析多媒体课件与课堂教学质量的关系

本文分析了影响高等学校课堂教学质量的主要因素,初步探索了多媒体课件与课堂教学质量的关系问题,在此基础上,提出了合理运用多媒体课件的几点建议。     

论实然状态视野中的权力制约

以往人们对权力制约的关注视角和研究方法过于注重其“应然”性而忽略其“实然”性,使得所形成的权力制约理论并不能真正在实际工作中发挥作用。权力制约应当从权力存在和运行的实然状态入手,在构成权力存在和运行系统的各个方面进行制约,最终保障权力的准确运行。     

浅谈英语口译工作者的素质要求

翻译是一种主动的再创造性质的工作，它需要翻译工作者首先在业务上具备较高的素质，即：敏锐的听力、较强的理解力以及清晰的表达能力，其次要善于运用多种翻译技巧和手段，此外，还需注意其它非语言素质和能力的培养。     

论徐訏小说中的暗示艺术

徐訏深受中西方文化的影响,善于在小说创作中运用暗示艺术,在其部分小说中的标题设置、人物命名、意象选择、景物描写、细节设置上都有明显的体现。暗示艺术的运用,一方面能使抽象的情感具象化,促进读者与作者之间的交流;另一方面也让徐訏小说呈现出简约含蓄的文体风格。     

Analysis of means approach for random factor analysis

Analysis of means (ANOM) is a powerful tool for comparing means and variances in fixed-effects models. The graphical exhibit of ANOM is considered as a great advantage because of its interpretability and its ability to evaluate the practical significance of the mean effects. However, the presence of random factors may be problematic for the ANOM method. In this paper, we propose an ANOM approach that can be applied to test random effects in many different balanced statistical models including fixed-, random- and mixed-effects models. The proposed approach utilizes the range of the treatment averages for identifying the dispersions of the underlying populations. The power performance of the proposed procedure is compared to the analysis of variance (ANOVA) approach in a wide range of situations via a Monte Carlo simulation study. Illustrative examples are used to demonstrate the usefulness of the proposed approach and its graphical exhibits, provide meaningful interpretations, and discuss the statistical and practical significance of factor effects.     

Irregularly observed time series – some asymptotics and the block bootstrap

We consider time series being observed at random time points. In addition to Parzen's classical modelling by amplitude modulating sequences, we state another modelling using an integer-valued sequence as the observation times. Limiting results are presented for the sample mean and are generalized to the class of functions of smooth means. Motivated by the complicated limiting behaviour, (moving) block bootstrap possibilities are investigated. Conditional on the used modelling for the irregular spacings, one is lead to different interpretations for the block length and hence bootstrap approaches. The block length either can be interpreted as the time (resulting in an observation string of fixed length containing a random number of observations) or as the number of observations (resulting in an observation string of variable length containing a fixed number of values). Both bootstrap approaches are shown to be asymptotically valid for the sample mean. Numerical examples and an application to real-world ozone data conclude the study.
