中英学习者使用迂回使役构式的对比研究

对本族者口笔语语料库（BNC）和中国大学生英语口笔语语料库（SWECCL-C）中出现的迂回使役构式展开深入研究,分析对比了英语本族语者与中国大学英语学习者在使用迂回使役构式方面的特点,通过分析得知中国大学生倾向于使用高频使役动词引导迂回构式,造成这一现象的主要原因：一、英汉语言文化在使役表达上的差异;二、英汉文化不同造成对“使役”的理解差异。而母语的负迁移现象是影响二语习得的最主要因素。     

Examination and visualisation of the simplifying assumption for vine copulas in three dimensions

Vine copulas are a highly flexible class of dependence models, which are based on the decomposition of the density into bivariate building blocks. For applications one usually makes the simplifying assumption that copulas of conditional distributions are independent of the variables on which they are conditioned. However this assumption has been criticised for being too restrictive. We examine both simplified and non‐simplified vine copulas in three dimensions and investigate conceptual differences. We show and compare contour surfaces of three‐dimensional vine copula models, which prove to be much more informative than the contour lines of the bivariate marginals. Our investigation shows that non‐simplified vine copulas can exhibit arbitrarily irregular shapes, whereas simplified vine copulas appear to be smooth extrapolations of their bivariate margins to three dimensions. In addition to a variety of constructed examples, we also investigate a three‐dimensional subset of the well‐known uranium data set and visually detect the fact that a non‐simplified vine copula is necessary to capture its complex dependence structure.     

从认知角度讨论现代汉语定语从句

本文从认知角度出发,调查现代汉语定语从句在口语和书面语篇章处理中的分布情况,研究造成这些分布的潜在因素,探讨并试图揭示此类从句的句法结构及它们在汉语篇章中的具体表现形式。     

汉语同位结构的理性意义限制

同位结构的成分在语法上并不存在必然联系,那么,究竟什么样的词与什么样的词才能结合构成同位结构?从语义学的角度分析,我们认为,汉语同位结构的成立及其结构类型要受三个条件的制约:同位成分的理性意义的意义类别相同、理性意义的语法特征相容、理性意义指称功能的强弱互补。     

Bayesian model selection for D‐vine pair‐copula constructions

In recent years analyses of dependence structures using copulas have become more popular than the standard correlation analysis. Starting from Aas et al. ( 2009 ) regular vine pair‐copula constructions (PCCs) are considered the most flexible class of multivariate copulas. PCCs are involved objects but (conditional) independence present in data can simplify and reduce them significantly. In this paper the authors detect (conditional) independence in a particular vine PCC model based on bivariate t copulas by deriving and implementing a reversible jump Markov chain Monte Carlo algorithm. However, the methodology is general and can be extended to any regular vine PCC and to all known bivariate copula families. The proposed approach considers model selection and estimation problems for PCCs simultaneously. The effectiveness of the developed algorithm is shown in simulations and its usefulness is illustrated in two real data applications.

论元构架视角下英汉中动结构的特点

从论元构架的视角,基于论元构架特有的认知优点,如完型整体性、形义配对及隐喻延伸性等,分析了英汉中动结构的句法、语义特征,探讨了中动结构主语、动词和附属语选择限制的认知理据,使这一特殊的语言现象得到了更合理的解释。     

公民基本道德规范刍论

在“爱国守法、明理诚信、团结友善、勤俭自强、敬业奉献”的20个字公民基本道德规范中,爱国守法是公民的首要的道德责任;明理诚信是公民良好道德素质的表征;团结友善是公民必备的思想品德;勤俭自强是公民可靠的立身途径;敬业奉献是公民崇高的精神境界。它们环环紧扣,层层递进,构成一个紧密联系、不可分割的完整体系。     

构块语法之简评

构块语法(Construction Grammar)是以认知语言学为理论背景、由Adele E.Goldberg和Paul Kay等在20世纪90年代提出来的语法理论。构块语法力图解释语言中的所有现象,论元结构研究和有标记构块的研究是其成果最突出的两个领域。构块语法的一个基本观点是:构块是形式和意义的结合体,即使是在具体词语缺席的情况下也具有与形式相应的意义和语用功能。本文对构块语法的历史与现状、基本特征、研究中心和应用前景作一简述。
