文学是人类存在的家园,解读文本是文艺学方法论的核心.中西方文艺学方法论的同一性即以社会和历史为视角,破译语言的能指和所指,考察读者的接受;民族性即中国重整体审美与感悟,西方重客观分析与体系建构;当代性则是多元性与开放性.马克思主义文艺学就是在这种格局中获得新的更大的发展. 相似文献

It is shown that when a parameter lying in a sufficiently small interval is to be estimated in a family of uniform distributions,
a two point prior is least favourable under squared error loss. The unique Bayes estimator with respect to this prior is minimax.
The Γ-minimax estimator is derived for sets Γ of priors consisting of all priors that give fixed probabilities to two specified
subintervals of the parameter space if a two point prior is least favourable in Γ. 相似文献

借助Pragglejaz团队的“隐喻识别程序”对《抗击新冠肺炎疫情的中国行动》白皮书中的隐喻进行分类描述,从认知关联视角切入对各类隐喻翻译进行案例分析。为实现白皮书类外宣文本国际传播的最佳社会效益,最大语境效果、共同的语境假设以及交际传播的目的是译者在实现隐喻跨语际转换时的重要考量准则。 相似文献

This paper provides an overview of retirement patterns in Hong Kong on the basis of limited data. A censored regression model
is used to infer the retirement age from people‘s current retirement status and their current age. This model is equivalent
to a restricted probit model, and the interpretation of parameters is straightforward. The results clearly show a negative
income effect on the retirement decision. The retirement age seems to be positively related to lifetime earnings but negatively
related to the rate of decline of earnings with age.

This paper models household fertility decisions by using a generalized Poisson regression model. Since the fertility data
used in the paper exhibit under-dispersion, the generalized Poisson regression model has statistical advantages over both
standard Poisson and negative binomial regression models, and is suitable for analysis of count data that exhibit either over-dispersion
or under-dispersion. The model is estimated by the method of maximum likelihood. Approximate tests for the dispersion and
goodness-of-fit measures for comparing alternative models are discussed. Based on observations from the Panel Study of Income
Dynamics of 1989 interviewing year, the empirical results support the fertility hypothesis of Becker and Lewis (1973).

The purpose of this study was to evaluate one phase of a statewide program of deinstitutionalizing developmentally disabled individuals. Forty adults who had spent a minimum of six months in community placements were evaluated with respect to changes in behavior associated with movement out of state institutions and into community settings such as group homes and day activity centers. Pre- and post-deinstitutionalization measures were taken with the Behavior Development Survey. Post-deinstitutionalization measures on Cataldo and Risley's Resident Activity Manifest were compared to the same measures obtained on 159 developmentally disabled individuals scheduled for deinstitutionalization. A consistent pattern of positive changes on both instruments favored deinstitutionalization, but changes could not be unequivocally attributed to movement out of the institutions per se. 相似文献

The purpose of ISO 9001:2000 Quality Management System (QMS) is to provide businesses with a model to grow systematically while assuring the quality of their products. The validity of ISO 9001:2000 QMS stems, largely, from the fact that the best minds worldwide have contributed to its development and maintenance, and the fact that many companies have reported real business gains because of its implementation. Unfortunately, many small businesses fail to survive due to the absence or lack of adequate system for managing quality. An obvious recommendation would be to implement ISO 9001:2000 QMS. Nevertheless, small businesses often cite lack of resources and time as the main reasons for not implementing ISO 9001:2000 QMS. 相似文献

弹性资本充足率监管加刚性杠杆率监管存在机理性缺陷。弹性资本充足率监管会影响刚性杠杆率监管的效果,刚性杠杆率监管也不能体现杠杆累积在时间维度和空间维度风险的变化。若引入弹性杠杆率缓冲,刚性杠杆率监管加弹性资本充足率监管的机理性缺陷就可以避免。因此,有必要实施弹性杠杆率监管,杠杆率的弹性化程度与银行的系统重要性程度相对应。 相似文献

In this article, a system that consists of n independent components each having two dependent subcomponents (Ai, Bi), i = 1, …, n is considered. The system is assumed to compose of components that have two correlated subcomponents (Ai, Bi), and functions iff both systems of subcomponents A1, A2, …, An and B1, B2, …, Bn work under certain structural rules. The expressions for reliability and mean time to failure of such systems are obtained. A sufficient condition to compare two systems of bivariate components in terms of stochastic ordering is also presented. 相似文献
