新诗的句式变异修辞

新诗句式变异修辞手段表现在省略、倒装、重复、凝缩、表里等几个主要方面,各种手段的具体运用、修辞意图和修辞效果等也表现出不同于日常语言、古诗语言的特色。新诗句式变异的探讨表明,新诗句式运用灵活多样并与修辞密切关联。     

高等职业院校计算机教学模式的构建

教学质量标准的关键在于教学过程模式的设计。改革传统的教学方式,对于当前计算机教育的发展尤其重要。本文针对高等职业教育计算机专业教学模式的构建提出建议。     

碰撞与调适：1942年的延安文学生态

在革命现实主义的发展历程中，合法的红色政权延安边区政府的出现，为革命现实主义文学带来了新的生机和新的本质。对于自由的个性化的20世纪30年代左翼文学来说，延安时期是一个左翼知识分子与政党国家之间的碰撞时期，当然也是一个相互磨合，并最终以左翼知识分子调整自我以适应环境的时期。这一时期对中国现代文学的当代化至关重要，它奠定了当代左翼知识分子与政党国家之间关系的基本格局，也形成了当代文学的基本的制度，更为当代文学的创作倾向确立了总体的方向。     

社会工作教育的理论与实践的再反思——以中国高校社会工作专业课程设计为例

自改革开放以来,中国高校社会工作专业课程正处于理论与实践的探索及初步发展之中。从课程设计的范式看,当今中国高校社会工作专业课程采取的是以科目为本的主流传遁模式,这种理性主义模式十分注重课程的规范化、体系化、学科化,但又缺乏弹性的课程设计空间。为此,笔者在对科目为本的社会工作专业课程理念的反思及建议融入批判实践范式的基础上,进一步从泰勒的课程原理的线性程序框架出发,具体地提出了目前我国高校社会工作专业课程的改革方向。     

利益格局的嬗变与道德指向的调整

伴随着社会转型,中国社会利益格局和价值观念呈现多元化态势,但文化道德理念在许多方面还停留在与一元社会相契合的水平,并没有从总体上应答现代社会转型所提出的新要求。市场经济作为一种经济运行机制,有其自身的道德要求,需要道德规范的支持。市场的逐利行为并非天然合理,它必须是有约束的;而且市场经济并非是我们社会生活的全部,所以我们仍然需要一种超越性的道德指引。     

Minimum aberration and model robustness for two-level fractional factorial designs

The performance of minimum aberration two-level fractional factorial designs is studied under two criteria of model robustness. Simple sufficient conditions for a design to dominate another design with respect to each of these two criteria are derived. It is also shown that a minimum aberration design of resolution III or higher maximizes the number of two-factor interactions which are not aliases of main effects and, subject to that condition, minimizes the sum of squares of the sizes of alias sets of two-factor interactions. This roughly says that minimum aberration designs tend to make the sizes of the alias sets very uniform. It follows that minimum aberration is a good surrogate for the two criteria of model robustness that are studied here. Examples are given to show that minimum aberration designs are indeed highly efficient.     

Test inversion bootstrap confidence intervals

In this paper we explore the theoretical and practical implications of using bootstrap test inversion to construct confidence intervals. In the presence of nuisance parameters, we show that the coverage error of such intervals is O ( n ^−1/2) which may be reduced to O ( n ⁻¹) if a Studentized statistic is used. We present three simulation studies and compare the performance of test inversion methods with established methods on the problem of estimating a confidence interval for the dose–response parameter in models of the Japanese atomic bomb survivors data.

DISTRIBUTION OF THE LEAST SQUARES ESTIMATOR IN A FIRST-ORDER AUTOREGRESSIVE MODEL

This paper investigates the finite sample distribution of the least squares estimator of the autoregressive parameter in a first-order autoregressive model. A uniform asymptotic expansion for the distribution applicable to both stationary and nonstationary cases is obtained. Accuracy of the approximation to the distribution by a first few terms of this expansion is then investigated. It is found that the leading term of this expansion approximates well the distribution. The approximation is, in almost all cases, accurate to the second decimal place throughout the distribution. In the literature, there exist a number of approximations to this distribution which are specifically designed to apply in some special cases of this model. The present approximation compares favorably with those approximations and in fact, its accuracy is, with almost no exception, as good as or better than these other approximations. Convenience of numerical computations seems also to favor the present approximations over the others. An application of the finding is illustrated with examples.     

中国政治权威治理模式利弊分析

经过20多年的改革开放,当代中国已经不再是计划经济时代高度政治化、高度集权意义上的社会主义权威主义国家体制,而是显现出一种新权威治理模式。然而,随着日常生活中的新型的契约性人际关系通过讨价还价而体现的妥协机制以及与此相对应的法制观念、新型的宽容的政治文化的出现,新权威治理模式面临着特别是来自合法性危机的挑战。中国唯有从权威治理逐步向分权的民主政治体制转变,才能打破发展的瓶颈,实现经济、社会和政治的良性互动。
