英语学习中的语言迁移现象分析

以英语学习中出现的正向迁移和负向迁移为例证,分析汉语对学习英语所产生的影响,而重点论述以汉语为母语的思维定势对英语学习产生的负向迁移影响,并提出了如何排除母语干扰的若干意见。     

走向多元化的儿童文学理论研究

新时期以来,儿童文学理论研究走向了多元化,理论研究的多元化集中在两个层次上:一是儿童文学的功能性研究;二是儿童文学接受主体的研究。     

刑事违法观与犯罪构成关系论

按照主观违法论而加以建构的传统犯罪构成理论有别于按客观违法论建构的大陆法系犯罪论体系,两者有着不同的研究进路和研究方法。主观违法论强调有责之违法,行为人的主观罪过、客观的危害行为、刑事责任能力都是违法的构成要素,这种因人而异的违法观不能很好地为司法实践提供理论根据。从主观违法论立场出发,我们不可能从构成要件其中一个方面单独地判断违法性是否存在,传统犯罪构成理论将犯罪构成要件定位于反映行为社会危害性的事实特征,因此,犯罪构成只反映定罪结论,不反映定罪过程。     

Diagnostics for dependence within time series extremes

Summary. The analysis of extreme values within a stationary time series entails various assumptions concerning its long- and short-range dependence. We present a range of new diagnostic tools for assessing whether these assumptions are appropriate and for identifying structure within extreme events. These tools are based on tail characteristics of joint survivor functions but can be implemented by using existing estimation methods for extremes of univariate independent and identically distributed variables. Our diagnostic aids are illustrated through theoretical examples, simulation studies and by application to rainfall and exchange rate data. On the basis of these diagnostics we can explain characteristics that are found in the observed extreme events of these series and also gain insight into the properties of events that are more extreme than those observed.

会计信息可靠性与相关性的产权博弈分析

从产权经济学角度对会计信息的产权属性进行分析,把会计信息的产权主体定位为所有的信息使用者,认为会计信息的产权主体与会计信息质量特征之间存在密切关系。不同产权主体之间为有利于自身的信息进行博弈,可靠性和相关性孰轻孰重取决于各方在博弈中的力量对比。最后,文章提出重构会计信息市场、实现可靠性和相关性协调发展的若干对策。     

R12在水平管内流动沸腾换热实验研究

本文对R12在水平管内流动沸腾换热特性作了实验研究。实验结果表明,管内流动沸腾换热与单相对流换热一样,存在热进口效应,国外早期的实验数据由于未能考虑热进口效应而偏大。实验结果还表明,水平流动沸腾周向不均匀换热主要受流动结构影响;截面平均换热系数则与质量流速、热流密度、质量干度和蒸发压力密切相关。分析实验数据证实,流动沸腾换热是由气泡产生而引起的流动充分发展核态沸腾和双相对流蒸发两部分组成的。本文的实验数据与国外已有的换热关系式能较好吻合。     

LLSM在群体判断中的推广和应用

LENGTH-BIASING, CHARACTERIZATIONS OF LAWS AND THE MOMENT PROBLEM

A positive random variable X with a finite mean has an induced length-biased law represented by Y, and Y is stochastically larger than X. An independent uniform random contraction of Y, UY, has the same law as X if and only if the latter is exponential. This property is extended to non-uniform contractions and a more general notion of length-biasing. The distributional equality of X and W leads to a functional equation for the moment function of X, which has either Infinitely many solutions or none. When U is constant, X can have a log-normal law, but it can also have laws with the same moment sequence as this log-nod law. The case where U has a certain beta, or generalized beta, law give t3 characterizations of generalized gamma laws, or to products of independent copies of them. This occurs even when these laws are not determined by their moment sequences.     

论魏晋南北朝时期儒学的衰落

魏晋南北朝时期是我国学术思想多元化发展时期。期间玄学兴盛,佛道流行,而在两汉居于统治思想地位的儒学却衰落不堪。本文从魏晋南北朝时期的社会特点、学术思想盛衰消长的客观情势以及儒学自身的状况去探究儒学衰落的原因,以有助于总结思想史发展的一般规律。
