双关语的语用解释与翻译

双关语是中外文学作品中常用的一种修辞手段,对双关语的解释和翻译是解析文学作品的难点。从语用认知及关联理论分析了双关语的理解过程,并从语用翻译的角度探讨了双关语的三元翻译理论,提出双关语的翻译是一个复杂的双重推理活动,是译者对双关语原话语的理解和把握以及对译语文化和译语读者期待的一个估计过程。

波德里亚早期思想发展的双螺旋结构

波德里亚整个早期思想是围绕着“符号”与“象征”的双螺旋上升运动来展开的。其中,二者的关系是核心线索,主要从象征社会与现代社会、象征性交换与符号价值、象征性交换与商品交换等一系列对立体现出来。符号与象征双螺旋的上升运动,也是对西方社会和文化的现代化过程的阐释。这一过程实际上就是符号秩序压抑和取代象征秩序, 象征秩序又不断挑战符号秩序的过程。因此,对现代性的反思和批判,就成为波德里亚著作的核心主题,象征性交换则成为其基本立场。     

高质量发展背景下现代服务业经济增收效应研究——基于重庆市的实证分析

现代服务业的高质量发展在一定程度上决定着当前阶段我国社会主义现代化水平,这是未来一定时期内实现经济发展和产业转型升级的关键引擎。通过择取1996—2017年全国层面的平衡面板数据,基于双重差分法和合成控制法对现代服务业综合政策在重庆市产生的经济增长效应做出合理化评价。实证结果表明：整体而言,现代服务业综合政策对重庆市产生明显经济增收效应。随着时间的推移,这种增收效应具有显著促进作用,但其通过政策红利动力驱动而产生的边际效应却趋于弱化。为解决内生性问题,通过进行一系列安慰剂检验,确保结论的稳健可靠。     

Hayter and Tsui's test with double sampling for the vector mean of multivariate normal population

Abstract

In this paper, we introduce a version of Hayter and Tsui's statistical test with double sampling for the vector mean of a population under multivariate normal assumption. A study showed that this new test was more or as efficient than the well-known Hotelling's T² with double sampling. Some nice features of Hayter and Tsui's test are its simplicity of implementation and its capability of identifying the errant variables when the null hypothesis is rejected. Taking that into consideration, a new control chart called HTDS is also introduced as a tool to monitor multivariate process vector mean when using double sampling.     

A note on a modified double stage shrinkage estimator

A modified double stage shrinkage estimator has been proposed for the single parameter θ of a distribution function _Fθ. It is shown to be locally better in comparison to the usual double stage shrinkage estimator in the sense of smaller mean squared error in a certain neighbourhood of prior estimate θ_o of θ.

通过建立灰色异构数据"核"序列的DGM(1,1)模型,实现双重异构数据"核"的预测;以"核"为基础、以双重异构数据序列中较大的区间灰数信息域作为预测结果的信息域,构建基于区间灰数与实数的双重异构数据序列灰色预测模型,有效地将灰色预测模型建模对象从"同质数据"拓展至"双重异构数据"。研究成果对丰富灰色预测模型理论体系具有积极意义。     

New two-stage sampling designs based on neoteric ranked set sampling

Neoteric ranked set sampling (NRSS) is a recently developed sampling plan, derived from the well-known ranked set sampling (RSS) scheme. It has already been proved that NRSS provides more efficient estimators for population mean and variance compared to RSS and other sampling designs based on ranked sets. In this work, we propose and evaluate the performance of some two-stage sampling designs based on NRSS. Five different sampling schemes are proposed. Through an extensive Monte Carlo simulation study, we verified that all proposed sampling designs outperform RSS, NRSS, and the original double RSS design, producing estimators for the population mean with a lower mean square error. Furthermore, as with NRSS, two-stage NRSS estimators present some bias for asymmetric distributions. We complement the study with a discussion on the relative performance of the proposed estimators. Moreover, an additional simulation based on data of the diameter and height of pine trees is presented.
