Generation of multivariate distributions by vertical density representation

Troutt (1991,1993) proposed the idea of the vertical density representation (VDR) based on Box-Millar method. Kotz, Fang and Liang (1997) provided a systematic study on the multivariate vertical density representation (MVDR). Suppose that we want to generate a random vector X[d]Rⁿthat has a density function ?(x). The key point of using the MVDR is to generate the uniform distribution on [D]_?(v) = {x :?(x) = v} for any v > 0 which is the surface in RⁿIn this paper we use the conditional distribution method to generate the uniform distribution on a domain or on some surface and based on it we proposed an alternative version of the MVDR(type 2 MVDR), by which one can transfer the problem of generating a random vector X with given density f to one of generating (X, X_n+i) that follows the uniform distribution on a region in Rⁿ⁺¹defined by ?. Several examples indicate that the proposed method is quite practical.     

基于数理逻辑的知识表示

数理逻辑是一种基于命题与谓词分析的形式化的语言及其推理，是人工智能产生和发展的最重要的基础。从逻辑推理、自然语言形式化、数学命题形式化及动态系统行为描述四个方面入手，提出了基于数理逻辑的知识表示方法与实例，并提出谓词逻辑的局限与应当进一步研究的问题。     

Bisexuals Making Out with Cyborgs: Politics, Pleasure, Con/fusion

This article considers the appeal of the figure of the cyborg for bisexuals, offering bisexual readings of both Donna Haraway's cyborg, and of the cyborg self created within text-based virtual reality. The writer argues that understanding bisexuality as part of a web of meanings and material realities can lead to a new political awareness, and suggests ways to make some of these connections. Through her analysis, she emphasises the role of technology in creating and developing contemporary bisexuality.     

“又……又……”格式的语义分析

本文以大量实际语料为分析基础，在考察“又……又……”位序的基础上。对“又……又……”格式的内部语义关系、连接成分的概念关系及“又……又……”格式的语义表达功能进行了分析考察。     

命题态度句的成真条件

用动态认知逻辑特别是话语表现理论为主要研究工具,充分考虑语境因素,探讨命题态度句的语义解释,得出的结论是:(一)命题态度句的语义依赖于被报道的信念和解释者对信念主体的认知状态的表征的其它元素的交互作用;(二)对命题态度句的处理揭示了语义的动态更新过程。     

角色参照语法的分析框架及其解释能力探析

角色参照语法是20世纪70年代以来发展起来的一种结构功能语法。论文尝试评述其主要的语法分析框架,并以英语和汉语为例探究其对不同语言的解释能力。角色参照语法成功地将语篇、语用因素融入到句法结构的分析之中,因此,它不仅能够较好地解释英语等形合语言的结构特征,也适用于具有意合特征的汉语等语言的结构分析。角色参照语法比传统的形式语法具有更大的灵活性和适用性。     

厄德里克的力量书写——评《桦树皮小屋》

路易斯·厄德里克是印第安文学中最多产的作家之一,《桦树皮小屋》是其六部儿童小说中的一部。作品按照春夏秋冬四季安排结构,以印第安奥吉布瓦部姑娘奥玛凯阿丝为中心,展现印第安人的智慧、力量以及对自然、对本族群与异族的态度。厄德里克着重书写一种力量,小说结构安排上的四季循环,隐喻了印第安部落之间力量的传递。这种凝聚的力量生成于部落成员间对彼此的爱,以及印第安人与宇宙万物之间的爱。这种爱的循环,构成了一种强大的力量的循环,使印第安民族虽历经磨难,也有足够的力量和勇气挺过寒冬,迎来春华秋实。     

Not forgetting happiness: the tripartite model of disability and its application in literary criticism

This interdisciplinary article draws on the social sciences to posit a tripartite model from which literary research into disability can benefit. Ableism and disablism are defined by normative positivisms and non-normative negativisms respectively, but consideration is also given to non-normative positivisms. Informed by experiential knowledge, the model is illustrated with reference to a trilogy of literary representations of blindness: George Sava’s novel Happiness is Blind, Brian Friel’s play Molly Sweeney, and Stephen Kuusisto’s memoir Eavesdropping. The result is a complex reading that recognises problems but also non-normative renderings of happiness.     

基于扎根理论的中国企业克服外来者劣势的边界跨越策略研究

外来者劣势是新兴经济体跨国企业国际化过程中面临的显著劣势,现有理论在新兴经济体跨国企业如何克服外来者劣势研究方面存在缺口。选取4家中国跨国企业作为研究对象,采用扎根理论研究方法的三阶段编码程序对案例进行剖析,探索中国企业在发达国家克服外来者劣势的具体策略,构建以边界跨越为核心范畴的外来者劣势克服策略理论模型。研究结果表明,中国企业面临的外来者劣势主要来源于信息缺失和合法性缺失。边界跨越是克服外来者劣势的有效策略,其中信息内化通过设置边界跨越角色、聘请外部顾问、环境扫描、产品策略和信息内部整合等活动将外部环境信息传递到企业内部,提高企业获取异国环境信息的能力,降低不熟悉危害;有利的外部显示通过品牌营销、企业社会责任、名人效应和获取第三方认证等活动向环境释放积极的信息,提高企业的规范和认知合法性,降低歧视危害和关系危害。针对研究结论,从构建环境扫描系统和外部显示机制两方面对中国企业如何实施边界跨越、降低外来者劣势提出具体的管理启示。     

Strategic Intersectionality and Political Representation: Female Muslim Councilors in London

This article addresses questions of how race/ethnicity, gender, and religion influence political representation. We use original interview data to test a strategic intersectionality theory developed by Fraga and colleagues (2005) in the case of female Muslim councilors in London, the United Kingdom. The original strategic intersectionality theory proposes that women are more effective advocates for ethnic group interests due to their unique capacity to leverage three primary resources: a substantive policy focus, multiple identity advantage, and gender inclusive advantage. We modify the thesis by analyzing religion as an additional identity marker and further disaggregating the three primary sources of leverage. We use the modified thesis to test whether female Muslim councilors of three London boroughs are more effective advocates for Muslim interests than their non-Muslim colleagues. We find mixed evidence for the presence of the three sources of leverage associated with strategic intersectionality, resulting in a more complex theorizing of this phenomenon than that found in prior research. This study offers a new contribution to the operationalization of intersectionality and the literature on intersectionality and political representation.
