对概念隐喻理论的理性思考

概念隐喻理论从20世纪80年代起就一直是认知语言学领域研究的热点。但任何理论都不是完美无缺的,因此我们应该辩证地看待该理论的优缺点,从而促进其发展。从经验基础、双域映射模式、认知解释力等方面剖析概念隐喻理论,探讨该理论可能存在的问题,有助于概念隐喻理论以后的研究。     

以五大发展理念引领体育强国建设

摘要：运用文献资料法,对以五大发展理念引领体育强国建设进行了系统研究发现：以习近平同志为核心的党中央站在中华民族伟大复兴和人类文明发展的历史高度,深刻阐明了以创新、协调、绿色、开放、共享五大发展理念引领我国体育强国建设的新思想和新战略。五大发展理念奠定体育强国建设的理论基础和历史方位、勾划体育强国建设的顶层设计与逻辑进程、彰显体育强国建设的中国担当和方法论启示、凝聚体育强国建设的中国力量、铸就体育强国建设的中国方案。以五大发展理念引领体育强国建设思想是对中国特色社会主义体育发展规律的新认识,丰富和发展了中国特色社会主义理论体系和马克思主义体育思想。研究以五大发展理念引领体育强国建设将深化对中国特色体育发展理念的认识,增强中国体育发展的道路自信。     

整体政府视阈下的政策执行力研究

政策执行力是近年来学术界研究的热点。随着新公共管理理论的衰微,盎格鲁一撒克逊国家先后进行的整体政府改革,引起了人们的广泛关注,也为学者们研究政策执行力提供了新的视角。文章对整体政府的结构、伙伴关系及其运作机制与提高政府的政策执行力之间的关联性进行了梳理。     

零售商态度承诺和供应商权力使用间的互动关系研究

本文研究了零售商不同的态度承诺与供应商权力使用间的互动关系。通过对中国346对家用电器零售商--供应商关系的问卷调查,利用因子分析及结构方程模型验证了概念模型及假设。本文研究结果表明:供应商强制性权力的使用会增加零售商的算计性承诺,降低其忠诚性承诺,而供应商非强制性权力的使用会增加零售商的忠诚性承诺。同时零售商的算计性承诺会促使供应商更多地使用强制性和非强制性权力,而零售商的忠诚性承诺则会减少供应商强制性权力的使用,增加供应商非强制性权力的使用。     

基于语料库的商务英语语篇中的战争隐喻研究

在认知隐喻理论的框架内,以自建的小型商务英语语料库为基础,揭示隐喻“商务即战争”（BUSINESS IS WAR）在商务语篇中的表现形态,并在Halliday语域学说的视角下,进行了商务语篇与政治语篇的对比分析.我们发现,战争隐喻在商务语篇中构成了严密、完整、和谐的语义网络系统,极大地支持了商务英语语篇信息的构建和传达.与政治语篇相比,商务语篇的隐喻密度很小,源始域倾向于战争策略、靶等战争外围概念,而非杀戮、战斗等核心概念.造成这种差异的主要是语域学说中的语场和语式元素,与语旨没有关联.

Antioxidant and lipid lowering activities of Indian black tea

Indian black tea; CTC leaf and dust, produced by Tata Tea Limited, Kolkata, (India) was studiedin vitro as potential scavenger of oxygen free radicals. Super oxide anions were generated in a system containing xanthine—xanthine oxidase (enzymic system) and by NADH- phenozine methosulphate (non enzymic system). Anions were assayed in terms of uric acid formation and reduction of nitroblue tetrazolium salt, which were shown to be suppressed by tea extracts. Extracts from both leaf and dust also inhibted the formation of hydroxyl radicalsin vitro in the enzymic system comprising hypoxanthine—Cu⁺²—sodium ascorbate and xanthine oxidase and in non enzymic system of deoxyribose—Cu⁺²—sodium ascorbate and H₂O₂ as well as the Cu⁺² induced lipid peroxidation in human low density lipoprotein. Feeding with black tea in normal rats for sixty days increased their antioxidant activity and their liver microsomes were shown to be protected against peroxidation of lipids as stimulated by metal ions with enzymic or non enzymic reactants. Furthermore feeding with tea extracts in normal as well as triton WR—1339 induced hyperlipidemic rats caused decrease in their plasma levels of total cholesterol, phospholipids and triglycerides. The antioxidant and lipid lowering activities of both extracts from CTC leaf and dust tea was comparable and may be due to the presence of natural products like catechin and others.     

Simulation research of energy management strategy for dual mode plug-in hybrid electrical vehicles

In this paper, a plug-in hybrid electrical vehicle (PHEV) is taken as the research object, and its dynamic performance and economic performance are taken as the research goals. Battery charge-sustaining (CS) period is divided into power mode and economy mode. Energy management strategy designing methods of power mode and economy mode are proposed. Maximum velocity, acceleration performance and fuel consumption are simulated during the CS period in the AVL CRUISE simulation environment. The simulation results indicate that the maximum velocity and acceleration time of the power mode are better than those in the economy mode. Fuel consumption of the economy mode is better than that in the power mode. Fuel consumption of PHEV during the CS period is further improved by using the methods proposed in this paper, and this is meaningful for research and development of PHEV.
