母语文化在英语语言教与学中的认知正迁移效用

母语文化的缺失是当前中国大学生英语语言学习中普遍存在的问题,忽略了母语文化的英语教学阻碍了学习者跨文化交际能力的培养。该文分析了"母语文化"在提高学生英语水平、提高学生跨文化交际能力及弘扬中国传统文化方面所起的认知正迁移效用,呼吁在英语教学中不仅要改变传统的英语学习观念,培养第三空间意识,还要加强母语文化的传承,使得母语文化在多元文化互动中知彼知己,融合互补,共同发展。

个体异质性、效用认知与绿色产品的定价策略

基于消费者个体异质性和绿色产品效用认知差异性,结合互联网背景,构建了绿色产品的发布式定价和协商式定价策略模型,探讨了不同绿色度、绿色效用认知、绿色成本水平下的定价策略采用时机。研究发现:在高绿色成本、低绿色效用认知的情况下应采用发布式定价;在低绿色成本或高绿色效用认知的情况下,基于绿色度的提高,协商式定价对厂商收益具有明显的加速作用,对于低绿色度的产品,应采用发布式定价,而对于高绿色度的产品,应采用协商式定价。

基于本土品牌刻板印象的感知效用分析及心理启动机制

从顾客感知效用大小决策行为出发,在本土品牌刻板印象心理作用下,分析顾客购买的信息性决策和行动性决策两阶段,构建顾客感知效用模型和本土品牌刻板印象的心理启动模型;进一步,分析了顾客个体特征、购买商品和所处环境均影响顾客的感知效用,从而影响顾客本土品牌刻板印象的启动;并讨论了各变量对顾客感知效用的影响,以此对购买做出判断。结论表明:顾客类型对购买有重要影响作用,通过不同效用敏感系数来影响购买,在本土品牌刻板印象下,顾客经济生活水平与购买正相关;需求时间和购买时间对购买具有负效应,商品认知评价和环境因素的影响认知与购买具有正效应;而其他各个环节成本减低对购买十分有利。

归纳认知过程中的价值因素

现代归纳逻辑产生之初,一些逻辑学家依照逻辑学求真的传统研究归纳推理前提的真对结论真的支持程度。随着研究的深入,价值因素进入归纳逻辑的视野,逻辑学家发现,在人的归纳认知过程中渗透着价值因素。

不确定信息静态博弈

传统的博弈理论中假定局中人具有共同知识 由于现实中各局中人获取信息的途径不同,信息具有不确定性,局中人具有共同知识这一假定往往不能满足 因此,需要讨论不确定信息博弈问题 基于认识效用决策理论,讨论了不确定信息静态博弈问题 假定各局中人仅知道其它局中人类型的分布,并利用拟Bayes理论建立了不确定信息静态博弈模型。

Optimal energy-efficient power control for cognitive radio based on static and dynamic features of primary users

In this paper, the energy-efficient power control problem in cognitive radio （CR） networks is studied not only to provide energy-efficient transmission, but also to guarantee the normal operation of primary users （PUs）. Moreover, the static energy-efficient power control （SEPC） algorithm is proposed in static scenario to maximize the capacity of secondary users （SUs） and to reduce the power consumption according to the interference from PU to SU. Furthermore, based on the analysis of PU＇s dynamic feature with Markov chain and SEPC algorithm,the dynamic energy-efficient power control （DEPC） algorithm is proposed taking into account the probability of detection and false alarm caused by sensing errors. Extensive simulation results show that the performance of the proposed algorithms is significantly improved compared with the existing algorithm.

Investigation on Fuzzy in English Literature Teaching

This thesis studies the concept and research background of filzziness and fuzzy theory, then committing further enumeration and analysis of the application of fuzzy theory in the fields of linguistics and literature. On this basis, the effectiveness and rationalization of the fuzzy theory＇s application in the English literature teaching were confirmed from many aspects. Among them, it is mainly investigated and analyzed from the objective factors and subjective factors. Subjective aspects mainly contain students＇ different cognitive ability, and the diversity existed in teachers＇ teaching and guiding methods. Objective aspects mainly include that the literature language and literature thoughts itself have the unique ambiguity. Finally, in summing up the investigation results the author put forward the essence of English literature teaching activity and put forward the methods to improve English literature teaching.
