试论咸同时期郭嵩焘的政治思想

郭嵩焘咸同时期的政治思想主要体现在他把官贪吏虐,政治黑暗看作是“致乱之源”,从而一方面极力主张“严以驭吏”,“肃清官吏之路”;另一方面也主张“宽以抚民”,反对严刑峻法．这些思想有助于我们理解郭氏后期思想的变化和发展,同时,对今天也不无借鉴意义．     

A two phases queueing system with Bernoulli vacation schedule under multiple vacation policy

This paper deals with a single server Poisson arrival queue with two phases of heterogeneous service along with a Bernoulli schedule vacation model, where after two successive phases service the server either goes for a vacation with probability p (0≤p≤1) or may continue to serve the next unit, if any, with probability q(=1−p). Further the concept of multiple vacation policy is also introduced here. We obtained the queue size distributions at a departure epoch and at a random epoch, Laplace Stieltjes Transform of the waiting time distribution and busy period distribution along with some mean performance measures. Finally we discuss some statistical inference related issues.     

回到索绪尔:论语言的本质及语言与文字的关系--与潘文国先生商榷

索绪尔关于语言的本质和语言与文字的关系的理论原理并未“过时”。探讨汉语汉字的特点和理论创新,不应背离普通语言学的基本原理。应完整、准确地把握索绪尔的理论体系,避免误读和误解。在研究的认识论和方法论上,以语言为出发点而不是以文字为出发点,以语素为语言分节本位,避免语音语义不同步的二元编码机制现象,至为关键。     

汉语时间概念隐喻的认知分析

隐喻不仅是一种语言现象,更是一种思维现象。人类通过其他具体概念来认知时间这一抽象概念。认知过程中,汉民族通过多种意象图式对时间概念进行建构。汉语中的时间概念隐喻分为时间是空间;时间是实体;时间是金钱。形成方位隐喻、实体隐喻、结构隐喻三种隐喻方式。汉语时间概念隐喻在人类语言尤其是在日常语言中占有重要地位。     

英汉词义的对比及翻译方法探究

语言翻译的过程不仅是简单的语言转换,更是两种思维方式和观念系统的相互作用及深化的过程。本文通过英汉词汇意义的构成、词义差别的对比,分析了两种语言之间产生差异的原因,并介绍了常见的翻译方法。     

多维视角下的元杂剧研究述评

20世纪元杂剧研究成就巨大,元杂剧研究更成为一门体系性的学科。关于元杂剧的研究文献相当丰富,研究者从各方面对元杂剧进行研究,如元杂剧的题材来源、元杂剧中所体现出的民俗文化、元杂剧所体现的语法、元代文人与杂剧兴盛相互关系等。总体看来,研究者研究方法的多样性和研究视角的多维性是20世纪元杂剧研究的主要特点。     

核心期刊的选刊依据及其冷思考

核心期刊产生于20世纪30年代的英国,它是期刊发展到一定历史阶段的必然产物,其理论依据是期刊集中与分散定律,即布拉德福定律。20世纪80年代中国科学院文献情报中心首先引进并开始研究核心期刊,其后一些研究单位也开展研究,取得了一系列开始性的成果。随着核心期刊影响力的不断扩大,并且这种影响力受期刊界和学术界的推波助澜,核心期刊在受到广泛关注的同时也引发了一些争议。不可否认,核心期刊确实存在一定的局限性,但它毕竟是一种客观存在,历史贡献功不可没,其积极的一面要远远大于其消极的一面。对待核心期刊应采取科学的态度,不能把它的作用推向极端,而应该克服它的局限性,科学合理地加以应用,使其在激活学术期刊市场、促进学术繁荣与发展方面发挥积极的作用。     

The empirical analysis of the -bilateral optimized combinatorial auction model

This study proposes a new and highly efficient dynamic combinatorial auction mechanism—the N-bilateral optimized combinatorial auction (N-BOCA). N-BOCA is a flexible iterative combinatorial auction model that offers more optimized trading for multiple suppliers and purchasers in the supply chain than one-sided combinatorial auction. We design the N-BOCA model from the perspectives of market architecture, trading rules, and decision strategy for winner determination, the decision strategy for winner determination needs flexible optimization modeling capability. Thus rule-based reasoning was applied for reflecting the flexible decision strategies. We also show the viability of N-BOCA through Paired Samples T-test experimentation. It shows that N-BOCA yields higher purchase efficiency and effectiveness than the one-auctioneer to multi-bidders (1-to-N) combinatorial auction mechanism.     

消费者网络信息可信度感知影响因素的实证研究

为了了解消费者对网上商品信息的可信度评价及其影响因素,采用了相关分析、结构方程模型等分析方法对通过调查表收集到的数据进行统计分析。研究结果表明,消费者对网上信息的可信度评价影响着消费者对网络信息的使用：消费者最信任的网络信息来源是网上中性信息,即来自综合或专业网站上的相关产品新闻报道、行业调查报告等信息,最不信任的是来自网络广告的信息：消费者对网上信息信任度与网络使用、网络知觉有用性、网络知觉易用性以及信任倾向正相关,与消费者的网络依赖程度无关。     

Music,rowing, and the aesthetics of rhythm

Having “good rhythm” is essential in both music and competitive rowing, but what exactly constitutes “good rhythm,” and how do we achieve it? Although rhythm is often discussed in purely auditory terms, I argue that rhythm is fundamentally a multisensory, kinesthetic phenomenon. By drawing parallels between music and rowing, I illustrate how biological motion principles underlie the parameters of rhythm in both disciplines, and how the cognition and appreciation of rhythm is deeply embodied. I suggest that the two main ways in which rhythms generate pleasure in both music and rowing are by enabling behavioral synchrony between individuals, and by engaging the body in the cognitive process of rhythm perception and prediction. In essence, “good rhythm”—a rhythm that is enjoyed and appreciated—is rhythm that moves.
