我国全国人民代表大会的代表数额分配的比例没有法定约束,地区与职业代表之间代表比的差别悬殊大。为了克服上述弊端,全国人大代表制度改革的方向是以废除职业代表制,落实公民实质平等选举权,照顾少数民族和人口较少区域为原则,废除预留代表惯例,完善华侨与港澳台代表之选举。  相似文献

母语心理词汇结构表征与二语心理词汇结构表征存在差异。母语心理词汇中词与词是以语义为联系的,而二语心理词汇中词与词的联系是语音起主要作用。学习者的二语产出性词汇能力到了某一阶段后出现"停滞现象",因此,为促进二语产出性词汇能力的发展,二语学习者有必要重组二语心理词汇结构并加深对单词的语义理解,不断地积累该词与其他词的语义联系。  相似文献

中国行政效率的公共选择理论分析   总被引:1,自引:1,他引:0  
从公共选择理论看来,政府在弥补市场失灵的同时,自身也会产生失灵。但是,中国在从计划经济向市场经济转型过程中,政府行政低效问题主要原因在于自身制度不够完善,如组织的约束机制和组织监控机制的不完善等。主要表现为政府决策达不到帕累托最优、无法评价市场机制与政府干预,何者的作用更大等。因此,必须通过引入竞争机制、进行成本-受益分析和加强监督等措施加以解决。  相似文献

散文是一种笔法灵活,把表象与意象之美融于一体,给人以深切情感体验的文学样式。作为散文翻译,不仅要传达原作之意,还要完整地再现原作的情、境,这也是评价译文质量高下的重要标准。以格式塔意象为理论基础,选取《英译中国现代散文选》为例,探讨散文翻译中情境再现的手段与技巧。  相似文献

Representations in popular media at the end of the twentieth century and the beginning of the twenty-first suggest that North American culture idealizes a kind of femininity constituted in erotic display while at the same time disavowing the parallel performance of that femininity in strip culture. This paper begins to consider why femininity is so insistently constituted on these terms, focusing in particular on women's advice media, self-help, and exercise programs of erotic dance as a domestic activity, and working to identify and understand the implications of that representation, for women who work as erotic dancers and for women who do not, with reference to the ways in which these two categories of femininity are constituted and maintained as separate categories through representation and to the effects of this separation for the labour of erotic dance and for the performance of femininity in the everyday. This paper undertakes to understand this complicated relationship and to determine what precisely is at stake in such representations, how to read them, and what they mean.  相似文献

It is proved that the accuracy of the bootstrap approximation of the joint distribution of sample quantiles lies between O(n?1/4) and O(n?1/4 an), where (log(n))1/2=O(an). As an application, we investigated confidence intervals based on the bootstrap.  相似文献

Expert Systems     
Summary

Expert systems are computer programs which embody the expertise of a human expert in order to consult and advise on a specific problem. It is now becoming feasible to apply expert systems technology to problems in the human services. This article describes what expert systems technology is and how it may be applied in human service practice. Finally, some of the promises and pitfalls of this new technology are addressed.  相似文献

How is ‘authentic’ linguistic femininity in Japan manifested in popular texts? We analyze the dialogue of female characters in Wakaba, a 2005 Japanese drama set in two very different parts of ‘regional’ Japan – Miyazaki and Kobe. Through this analysis, we examine two contradictory discourses circulated through popular media. The first is that linguistic femininity is based in Standard Japanese – a surprisingly persistent ideology despite a current trend to examine cases in which language ideology and practice do not match. Other studies reflect another dominant discourse, that of the ‘authentic’ dialect speaker, who expresses local alignment by using dialect forms outside the bounds of ideologically modern linguistic forms. The tension between acting linguistically feminine and ‘authentically’ local raises some interesting questions for Japanese language and gender studies, including studies of gendered representations: are women who are speakers of regional dialects authentically ‘feminine’? Can they be? Do some dialects express femininity better than others?  相似文献

The authors establish the joint distribution of the sum X and the maximum Y of IID exponential random variables. They derive exact formuli describing the random vector (X, Y), including its joint PDF, CDF, and other characteristics; marginal and conditional distributions; moments and related parameters; and stochastic representations leading to further properties of infinite divisibility and self-decomposability. The authors also discuss parameter estimation and include an example from climatology that illustrates the modeling potential of this new bivariate model.  相似文献

This article develops a class of the weighted normal distributions for which the probability density function has the form of a product of a normal density and a weight function. The class constitutes marginal distributions obtained from various kinds of doubly truncated bivariate normal distributions. This class of distributions strictly includes the normal, skew–normal and two-piece skew–normal and is useful for selection modelling and inequality constrained normal mean analysis. Some distributional properties and Bayesian perspectives of the class are given. Probabilistic representation of the distributions is also given. The representation is shown to be straightforward to specify distribution and to implement computation, with output readily adapted for required analysis. Necessary theories and illustrative examples are provided.  相似文献
