传统意义上的圣经汉译是将圣经原文语言信息转换成汉语来表达,让读者在汉语语境下以汉语思维模式领悟圣经原文的语言信息。而中文代表字原文新约圣经与此相反,它是以汉语符号系统展现新约圣经希腊原文的“原貌”,目的是让读者通过汉语进入希腊语原文语境,以希腊文的思维模式来体验经文原文信息,在翻译思想及翻译理念上具有很大程度的相“逆”性。试采用描述性翻译研究方法能够较好地阐释中文代表字原文新约圣经的翻译策略及其所体现的翻译思想与理念。  相似文献

This article considers estimation of the slope parameter of the linear regression model with Student-t errors in the presence of uncertain prior information on the value of the unknown slope. Incorporating uncertain non sample prior information with the sample data the unrestricted, restricted, preliminary test, and shrinkage estimators are defined. The performances of the estimators are compared based on the criteria of unbiasedness and mean squared errors. Both analytical and graphical methods are explored. Although none of the estimators is uniformly superior to the others, if the non sample information is close to its true value, the shrinkage estimator over performs the rest of the estimators.  相似文献

The purpose of this paper is to extend results obtained by Sahai and Anderson (1973) and Hurlburt and Spiegel (1976) computationally as well as theoretically. We apply results given in Yassaee (1974), (1976) and apply our computer program to show that one can evaluate the probability of type one error for conditional tests in linear model, in general. We show that one can compute the probability integral of Dirichlet distribution by the use of our program which computes the probability integral of inverted Dirichlet distribution.  相似文献

一般新闻论著中都强调导语是新闻写作的第一步,给人的印象是,倒金字塔的新闻语篇是先写导语的。关于标题、导语、事件主体、评价和预测这几部分,到底先写哪一部分,一般新闻论著中都没有明确。就初学者来说,先把主体事件写好后,再向两端发展,易写得较好。在新闻教学中应该明确这一思想。  相似文献

国有企业是国民经济的主导力量,其内部薪酬差距对企业诸多方面具有重大影响。运用2006—2017年制造行业的国有上市公司的相关数据,采用面板数据固定效应模型研究了企业内部高管—员工薪酬差距与企业绩效之间的关系,进一步利用面板门限模型探讨了薪酬差距对企业绩效激励效应的门限水平。研究发现,薪酬差距与企业绩效之间存在倒U型的关系,这说明两者之间的关系不能简单地仅用锦标赛理论或行为理论来解释。另外,在薪酬差距的正向效应范围内存在显著的门限特征,在门限值(32. 216)以下,薪酬差距对企业绩效有更强的激励效应,在门限值以上激励效应减弱。研究结论表明,应当深化国企改革,注重竞争和公平两个要素,科学设置薪酬差距区间,以充分发挥薪酬差距对企业绩效的正向激励效应。  相似文献

In this paper, the estimation of parameters for a generalized inverted exponential distribution based on the progressively first-failure type-II right-censored sample is studied. An expectation–maximization (EM) algorithm is developed to obtain maximum likelihood estimates of unknown parameters as well as reliability and hazard functions. Using the missing value principle, the Fisher information matrix has been obtained for constructing asymptotic confidence intervals. An exact interval and an exact confidence region for the parameters are also constructed. Bayesian procedures based on Markov Chain Monte Carlo methods have been developed to approximate the posterior distribution of the parameters of interest and in addition to deduce the corresponding credible intervals. The performances of the maximum likelihood and Bayes estimators are compared in terms of their mean-squared errors through the simulation study. Furthermore, Bayes two-sample point and interval predictors are obtained when the future sample is ordinary order statistics. The squared error, linear-exponential and general entropy loss functions have been considered for obtaining the Bayes estimators and predictors. To illustrate the discussed procedures, a set of real data is analyzed.  相似文献

This paper provides a Bayesian treatment of the problem of inference about the reliability of a multicomponent stress-strength system which functions if s or more of k identical components simultaneously operate. All stresses and strengths are assumed to be independent, exponentially distributed random variables. Exact and approximate asymptotic posterior distributions for the reliability are derived, and the results are illustrated by a numerical example.  相似文献

Improved James-Stein type estimation of the mean vector μ of a multovaroate Student-t population of dimension p with ν degrees of freedom is considered. In addition to the sample data, uncertain prior information on the value of the mean vector, in the form of a null hypothesis, is used for the estiamtion. The usual maximum liklihood estimator((mle) of μ is obtained and a test statistic for testing H0:μ=μ0 is derived. Based on the mle of μ and the tes statistic the preliminary test estimator (PTE), Stein-type shrinkage estimator (SE) and positive-rule shrinkage esiimator (PRSE) are defined. The bias and the quadratic risk of the estimators are evaiuated. The relative performances of the estimators are mvestigated by analyzing the risks under different condltlons It is observed that the FRSE dommates over he other three estimators, regardless of the vaiidity of the null hypothesis and the value ν.  相似文献

近年来,环境保护与经济增长之间的"两难悖论"引起了广泛的关注,环境规制强度如何影响经济增长的问题亟待解决。本文基于代际交替模型(OLG),将环境规制、健康人力资本及生产性资本纳入分析框架,指出环境规制通过影响健康人力资本和生产性资本投资的方式对经济增长产生正负两方面影响。当环境规制强度较低时,环境规制强度与经济增长率正相关;当环境规制强度过高时,则与经济增长率负相关,存在一个最优环境规制强度。在此基础上,利用我国1997-2015年30个省级的面板数据,通过广义矩估计进行实证研究,验证了在我国存在这种显著的"倒U型"的非线性关系。  相似文献
