等式主位与信息对应的功能分析

等式主位是一个以主位结构为起绪、主位对等为原型,融会扩展为Theme圮Rheme的语义结构体系。文章研析等式主位与主位对等的相似性和特殊性,探究连位与主/述位既凝聚又相互映射的信息对应关系。以往,主位/信息结构的相关研究唯独未对连位深入认知。其实,连位自身的概念、人际功能内化着主/述位的衔接并外化着转型变义的成因。本研究框架的“连位推进模式”将连位的能动推进力体现到句法中,使控制及物性小句一致性内部转换、向隐喻式外部转型的可操作性和阐释力得到增强,从而支持了等式主位的理据构建。

近十年来口译语料库研究现状及发展趋势

口译语料库建设与研究迄今仅有十余年历史。目前,已建和在建的口译语料库尚不到10个,最大的也不过100万字,而且种类单一(会议口译)、标注简单。相应的研究数量较少,集中在口译文本语言特征和口译操作过程两方面。因此,未来口译语料库建设应注重以下问题:多类型、不同性质语料库的建设与完善,语料库规模的扩大,停顿、填充语、省略等副语言信息的精确标注与转写,口译语料库的"信息对应",适合口译语料的检索工具的研发。同时,基于口译语料库的研究应该考虑多种研究方法的综合利用,集中讨论口译文本的语篇特征、口译实践策略、口译相关理论和概念的验证与发展等关键问题,促进口译研究与教学的协调发展。

The Operation Mechanism of Agricultural Products Supply Chain and Profit Allocation Model in the Context of Asymmetric Information

The research performed analysis on causes of asymmetric information of agricultural product supply chain and made conclusion on operation mechanism and characteristics of supply chain based on asymmetric information. Finally, the research detailed profit sharing of agricultural product supply chain in the context of asymmetric information and proposed suggestions, providing references of pricing and profit sharing of supply chains of agricultural products.

Coordinating pricing strategies in supply chain under asymmetric information and disruptions

The coordinating pricing strategies with asymmetric cost information under disruptions are investigated in a one-supplier-one-retailer supply chain system.While the retailer's cost structure is asymmetric information,supply chain pricing contract models(a wholesale price contract and an all-unit quantity discount contract)under asymmetric information are proposed by employing the principal-agent principle in a regular scenario.When the retailer's cost distribution is fluctuated by disruptions,we obtain the optimal emergency strategies of the supply chain under asymmetric information by considering deviation costs and show how to effectively handle the cost uncertainty.Using numerical methods,impacts of cost disruptions on the optimal wholesale price,the retailer price,the order quantity and the expected profits of the retailer,the supplier,as well as the total system are analyzed.It is found that the all-unit quantity discount policy can obtain better performance than the wholesale pricing policy.

Analysis on the Effect of Asymmetric Information on Product Supply Chain and Pricing

Along with the vigorous development of the markel economy, the transactions in the market are also increasingly frequent. In all kinds of market transactions, there are more or less inIbrmation asynunetry phenomena. Asynmaetric information makes supply chain unable to give a real reaction to the relationship between market supply and demand, and the personnel in the channels of supply chain are unable to make the optimal pricing, so that the overall profits are affected. Therefore, asymmetric information should be controlled within the normal range, for the purpose of ensuring the normal operation and healthy development of the market transactions.

Optimization of Supplier Switching with Asymmetric Information

The buyer-supplier relationship plays a great role in most economic systems. The buying firm usually tries to find a new supplier who provides products with satisfying quality and lower price. A broad branch of literature deals with the development of buyer-supplier relationships, but limited research is on the circumstances under which a buyer should terminate such a relationship and switch to a new supplier. In this paper, the incentive compatibility constraint (IC) which induces the entrant supplier to report his true cost is considered, and the participation constraint (PC) which ensures the entrant supplier to get at least reservation profit is taken into account. Then the supplier switching model is set up to minimize the buying firm's total procurement cost which includes the transfer payment to the incumbent supplier, the payment to the entrant supplier and the switching cost, and the buying firm's switching cost is considered as a function of the switching quantity. With the theoretical analysis of IC, PC and the proposed model, the optimal supplier switching strategy can be obtained. Finally, a numerical example is given to illustrate the effectiveness of the proposed model and the switching strategy.

重音理论及汉语重音现象

本文先讨论重音理论的起源、发展和现状,然后讨论重音在汉语中的体现,包括对普通话两字组重音新的分析,最后讨论汉语的特点对重音理论的意义。本文通过一系列例子说明,汉语的重音现象十分丰富,而且很多重音规律跟英语是一样的,如循环规则、声调-重音连接律、音步的定义和结构、韵母-重音对应律以及信息-重音对应律。这些研究不但可以进一步完善重音理论,而且说明,各种语言在重音方面的特性比前人想象的少,而重音的共性比前人想象的多。
