情态与情态系统的体现：系统功能语言学的视觉

从系统功能语言学的角度探讨英语情态的本质及其体现。情态本质上属于主观范畴,情态是由特定语句中的小句来实现的。语境对情态的体现及其意义的确定有着重要的作用,而句子的不同的构成方式所体现的情态在意义上有着取向的不同。     

Differential impact of Web site content: Exploring the influence of source (public relations versus news), modality,and participation on college students’ perceptions

This experiment examined the impact of source, modality, and participation on perceptions of credibility, salience, attitudes, and general Web site evaluation. The data showed no significant differences between online stories coming from either public relations or news sources on any of the study's dependent variables. However, significant differences did emerge for the effects of multimedia and audience engagement.     

A modified Conway–Maxwell–Poisson type binomial distribution and its applications

This article proposes a generalized binomial distribution, which is derived from the finite capacity queueing system with state-dependent service and arrival rates. This distribution is also generated from the conditional Conway–Maxwell–Poisson (CMP) distribution given a sum of two CMP variables. In this article, we consider the properties of the probability mass function, indices of dispersion, skewness and kurtosis, and give applications of the proposed distribution. The estimation method and simulation study are also considered.     

从阿维森纳的模态论证浅析“上帝存在论证”之“隐”

本文从阿维森纳对"上帝存在"的模态论证出发,综合其他历史上著名的论证,指出上帝存在论证似乎不可能跨越理性这个难关。由此转入对"人类理性之维(逻辑之维)是否无法打通有限世界与无限世界之间的门?"问题的探究,并对此问题背后的可能性原因进行分析。     

连词“如果”的使用动机

假设关系是一个拥有众多下位语义关系的语义框架。日语假设复句有众多的语言形式,各形式之间既有相通的用法也有独立的用法。汉语假设复句虽然也存在众多的语言形式,但各形式之间只有文体上的分工,没有语义上的差异。日语是通过切换语言形式、而汉语则是通过音韵操作来表现假设关系复杂的语义关系。也就是说,假设复句下位语义关系间的微妙差异在两语言中是通过不同的手段来表现的。再进“一步说,同一连词即使可以出现在不同下位语义关系的汉语假设复句中,该连词的使用动机也是不同的。该文以“如果”为例,通过语音实验证实了上述主张的正确性。     

从情态意义角度分析我国法庭判决书中的权力不对等性

法律语言是一种机构语言,它蕴涵着法律领域中各个实体之间的不同权力关系。本文在米歇尔·福柯（Michel Foucault）的权力话语理论框架下,分析法庭判决书中法官与诉讼人之间非平衡不对等权力关系的具体语言表现形式。

Modelling directional dispersion through hyperspherical log-splines

Summary.  We introduce the directionally dispersed class of multivariate distributions, a generalization of the elliptical class. By allowing dispersion of multivariate random variables to vary with direction it is possible to generate a very wide and flexible class of distributions. Directionally dispersed distributions have a simple form for their density, which extends a spherically symmetric density function by including a function D modelling directional dispersion. Under a mild condition, the class of distributions is shown to preserve both unimodality and moment existence. By adequately defining D , it is possible to generate skewed distributions. Using spline models on hyperspheres, we suggest a very flexible, yet practical, implementation for modelling directional dispersion in any dimension. Finally, we use the new class of distributions in a Bayesian regression set-up and analyse the distributions of a set of biomedical measurements and a sample of US manufacturing firms.     

副词“也”主观性的认知解释

本文从认知的角度对汉语副词"也"的主观性获得做出了解释,认为"也"字的功能多义性是说话人对"比较"框架主观识解的结果。也字句在现代汉语中的三种句法形式,对应"也"字主观性的不同程度表现。具有强烈主观性的语气副词"也",虽然"类同"义已经淡化,但"比较"框架还在起作用,作为程序信息,它引导听话人把话语前提和现实事件进行比较,得出说话人对现实事件的评价态度。     

英语广告语言的情态探析

韩礼德建构系统功能语法的目的之一是为语篇研究提供一个分析框架。本文从韩礼德人际功能理论中的情态系统入手,对英语商业广告语言的情态作简要的分析,以探求该类广告是如何运用情态手段达到其劝说目的的,从而对劝说性语篇的分析提供一些启示。
