论异体成语的类型和产生的原因

异体成语是对通用成语而言的。在成语发展过程中产生了大量的异体成语,经过历史的选择,确立了通用成语。由于多种选择的需要,便产生了多种形式的异体成语。

Unemployment and economic psychology: An introduction

Starting from literature a short sequential scheme is being presented, including contextual and causal factors of employment, phenomenal aspects of unemployment, moderator variables, effects and lastly interventions and solutions.General aspects as well as more restricted aspects of unemployment as an area of research within economic psychology are mentioned. The contributions within this issue are discussed in connection with the scheme and the different aspects that were distinguished.     

理论创新的知识形态及其实现的基本条件

理论创新并非是理论演进中“继承”关系的相对意义,它是知识存在的一种常态,重在知识生长过程中由“无”到“有”的零的突破,并对“习以为常”的错误知识进行矫正的过程。理论创新也不可能在知行合一的思维路径上获得生长的条件,唯有到个人差异和社会多样性中找到其存在的条件,而思想自由、批判精神、自由地交流意见与经验、“爱智慧”的时尚是4个基本条件。     

论英语部分亲属词的模糊性及汉译处理

英语亲属称谓是一个貌似容易,其实很棘手的翻译问题.主要原因在于中西文化中称谓体系的不对应,而英语部分亲属词的模糊性使得翻译更为困难.引用实例说明翻译困难所在及汉译处理.     

宁波历史文化转型探赜──兼论现实文化建设的方向

文化转型是一个客观的社会实际，也是文化发展演进的历史性标志。在宁波历史上，曾经出现过两次具有鲜明特色的文化转型期，其中，第一次转型发生在我国古代，南宋初年为关键的定型阶段，此次转型的结果是使宁波地区的文化形态由“未开化”走向“精致化”；第二次转型发生在我国近现代，民国年间为关键的定型阶段，此次转型的结果则使宁波地区的文化形态由“精致化”走向“世俗化”。种种迹象表明，当前正处于新一轮文化转型的关口，由“世俗化”迈进“现代化”应成为现实文化建设的方向。     

CONVERGENT SERIES EXPRESSIONS FOR INVERSE MOMENTS OF QUADRATIC FORMS IN NORMAL VARIABLES

Using relatively recent results from multivariate distribution theory, a direct approach to evaluating the inverse moments of a quadratic form in normal variables is proposed. Convergent infinite series expressions involving the invariant polynomials of matrix argument are obtained. The solution also depends upon a positive scalar which is arbitrarily chosen. For the solution to converge an upper bound upon this scalar is derived.     

On the distribution of quadratic forms in normal random variables

This paper provides necessary and sufficient conditions for a quadratic form in singular normal random variables to be distributed as a given linear combination of independent noncentral chi-square variables. Using this result, an extension of Cochran's theorem to quadratic forms of noncentral chi-square variables is derived.     

A note on the joint distribution of correlated quadratic forms

In the present paper, the authors obtained exact and asymptotic expressions for the joint distribution of correlated quadratic forms when the underlying distribution is a multivariate normal.     

Gammaization and wishartness of dependent quadratic forms

In this paper two equivalent sets of necessary and sufficient conditions are derived for dependent quadratic forms to be distributed as multivariate gamma distribution. The procedure also gives a set of necessary and sufficient conditions for principal minors of generalized quadratic forms to be jointly distributed as the joint distribution of principal minors of a Kishart matrix.
