Inventory Policy with Parametric Demand: Operational Statistics,Linear Correction,and Regression

In this paper, we consider data‐driven approaches to the problem of inventory control. We first consider the approach of operational statistics and review related results which enable us to maximize a priori expected profit uniformly over all parameter values, when the demand distribution is known up to the location and scale parameters. For the case of the unknown shape parameter, we first suggest a heuristic approach based on operational statistics to obtain improved ordering policies and illustrate the same for the case of a Pareto demand distribution. In more general cases where the heuristic is not applicable, we suggest linear correction and support vector regression approaches to better estimate ordering policies, and illustrate these using a Gamma demand distribution. In certain cases, our proposed approaches are found to yield significant improvements.     

文本语境与复义

"文本语境"的内涵除了"上下文"之外,还曾被瑞恰兹和巴赫金分别加以语义层面和话语层面的拓展,形成了另外两种更具广阔内涵的文本语境。三种文本语境都具有复义功能,为文学文本创造并保留复义。上下文的文本语境通过语词之间的语义交感,在语词的概念意义之外重组出新的整体意义,构成文学文本的基本意义;语义层面深邃而广阔的文本语境,以引入新信息的方式为解读意义提供更多可能,使文本意义呈现出复杂的复义状态;话语层面的文本语境,由语境和话语的多重性实现复义的创造,使某一话语在周围各种话语所构成的不同语境的折射中呈现不同的意义。     

论陈先发的诗歌修辞

独特的修辞更能成就个性化的诗人。近些年来,陈先发在诗歌创作上的修辞探索引起人们的关注：借故翻新的互文性写作,古诗意象的唤醒和现代灵魂的注入,使诗歌表现出对生存与写作的多重焦虑;人与物的通灵及轮回意识增强了诗的魔幻色彩,产生了第三者观察视角和意象指向不确定等美学效应。设置非象征与象征的迷宫,通过自然隐晦揭示生死意识;感觉的具象化与自然的典故化,使诗歌形象灵动;复杂的简单与意义的含混使诗歌语言节奏自然,语义多重可解,蕴藉深厚。     

口语产出质量与模糊容忍度的相关研究

以某大学的90名非英语专业学生为研究对象,利用Ely的模糊容忍度调查问卷（SLTAS）（1995）和两篇从GRE和TOEFL考试中选取的材料为主要测试工具,考察阅读中的模糊容忍度与口语产出质量的相关性.结果证明：模糊容忍度与口语产出质量存在显著正相关,模糊容忍度越高,其口语成绩也越高.模糊容忍度对口语的影响表现在流利性、完整性和准确性3方面,对语音和交际能力没有影响;对阅读中的模糊容忍度与随后口语产出之间的相关性存在性别差异,女生存在这种相关性,男生不存在.     

中国文学现代性的空间体验——兼与李欧梵先生商榷

李欧梵先生挖掘中国文学现代性的颓废面向意义重大,但他认为此种现代性的被压抑源于西方启蒙思想的影响,进而提出西方启蒙思想对中国影响最大的是时间观念的论断,这是值得商榷的。启蒙思想对中国时间观念的影响,并非如李先生所言如此巨大。从中国现代性的发生,利玛窦的地图开始部分瓦解中国天朝中心观念,到中国文学世界由于发现另一空间,由之更重视自身的空间体验,都可看出对现代性的空间的重视。     

Ambiguity and Cooperation in the Implementation of Adult Protection Policy

Using a classification of public policy developed by Matland, we examine implementation of policy on adult protection as outlined in ‘No Secrets’, the government's guidance to local agencies. This policy appears to exemplify a ‘high‐ambiguity/low‐conflict’ model. Detailed interviews with staff charged with developing multi‐agency procedures, in local authority departments, health authorities, the police and the voluntary sector, confirmed the ambiguity of the policy and the uncertainty experienced by staff as a consequence. However, the interviews also revealed a number of areas of conflict, particularly as people gave precedence to their own professional norms and organizational priorities over partnership working.     

文学作品中颜色词的模糊性及其翻译研究

俄罗斯文学作品中颜色词的语义和语用意义有时很难确定,具有模糊性。其模糊性主要体现在三个方面:多义项颜色词、单一颜色词、非概念意义颜色词。从语言模糊性的视角探讨文学作品中颜色词及其翻译策略具有一定现实意义。     

英语弹性思维探讨

针对英语弹性思维 ,以心理学、语言学为基础 ,运用了“黑箱”理论和功能模拟方法 ,对英语语言弹性现象进行分析。笔者认为 ,英语思维的弹性主要产生或存在于歧义、同一词义的语义特征变化、故事情节、变异结构、弯曲和摆动、“省略”句、数量、模糊语言、艺术语言、人思维强烈的模糊性和心物场中的力等方面。     

汉语歧义现象分析

汉语里的歧义现象种类繁多,常常在言语交际过程中影响正确的表达,并引起误会。本文从不同角度分析了歧义现象产生的原因,以及消除歧义的方法,全面深入地了解歧义现象,并且能够进行分化,将有助于我们正确运用祖国的语言,对提高语言的表达及写作能力大有裨益。     

Note passing as gendered practices of public ambiguity in a hyper‐masculine organization

This article explores a surprising and seemingly mundane organizational practice: passing notes during professional meetings. Based on 34 in‐depth interviews with women in a hyper‐masculine organization — the Israeli military — this study focuses on what I term gendered practices of public ambiguity. It demonstrates how these practices shed light on three interrelated paths to power at work: (i) practices of public intimacy between men; (ii) practices of women's degradation by men; and (iii) practices of recognition claims by women. The tension between the publicity inherent in the routine passing of notes and the ambiguity of their contents calls for a more nuanced theorization of gendered power practices, which transcends the accepted dichotomy of doing and undoing gender, reproducing or challenging the symbolic gender order. The findings show that gendered micro‐practices can become polysemic symbolic spaces in which women redirect the flow of power, if only temporarily and locally, and turn it into a multidirectional and multi‐agentic resource. The conceptual contribution of these findings is discussed in terms of the positioning of women in hyper‐masculine environments as pragmatic subjects who (re‐)construct mechanisms of power out of the restricted repertoire available to them.
