基于胜任特征和反馈控制模型的运筹学课程教学体系研究——以工商管理专业为例

作为基础课程与专业课的桥梁,运筹学是一门实践性很强的专业基础课。本文以工商管理专业为例,根据运筹学的特点和专业需求,设计并构建了基于胜任特征运筹学课程教学体系和反馈控制模式。该体系和模式充分考虑了工商管理专业综合能力培养的要求,以形成学生胜任特征为目标,信息反馈为调控手段,通过教学方式的完善,进行运筹学课程教学体系的改革尝试,最后提出了相应的对策建议。

从语言测试类型与教学反馈看大学英语考试改革作用

大学英语考试改革经过2005年的试点,2007年的实施,到2013年的微调已经引起了社会的广泛关注,也产生了诸多影响。本文就语言测试和语言教学关系,从英语的测试类型、考试功能来探讨大学英语考试改革作用。鉴于大众化高等教育时代的来临,本文提出公正有效的语言测试能对学生语言应用能力进行客观、公正的评价,强调大学英语教育仍要以语言知识的学习和基本技能的应用为主,并提出教学评价应所根据地区和院校的不同设置不同的标准,使学生健康成长。

IM反馈及时性对消费者态度和购买意愿影响的研究——产品类型和价格可议性的调节作用

即时通讯(Instant Messaging,IM)在网络购物中起着不可忽视的作用.本文通过对277名网络消费者进行情境模拟实验,探究了IM反馈及时性、产品类型和价格可议性三个变量对消费者态度及购买意愿的影响.结果表明:(1)IM反馈及时性对消费者态度和购买意愿具有显著正向影响:及时反馈比不反馈有更高的消费者态度和购买意愿;(2)产品类型在上述关系中有一定调节作用:体验型产品受IM反馈及时性的影响更大;(3)价格可议性并无显著调节作用.根据研究结果,从网络商家角度提出相应管理建议.     

Does personality predict tourism information search and feedback behaviour?

There is little research on how personality traits influence information search and feedback behaviour of tourism information consumers. Using various online and offline information and feedback sources, this study contributes to the literature by considering how personality influences Taiwanese view pre-trip and on-site information sources’ ability to provide desired information before and during the trip and whether post-trip feedback channels are suitable feedback instruments. Even though personality alone may not fully explain tourism information search behaviour, hierarchical regression analyses showed the usefulness of Big Five personality traits in this aspect. Openness to experience and conscientiousness traits particularly stood out. Openness to experience significantly affects perception of word-of-mouth-related sources and conscientiousness for less accessible sources. Extraversion and neuroticism negatively predict popular culture sources. These outcomes might be due to the attributes of information sources or feedback channels.     

Grey Power: An Empirical Investigation of the Impact of Parallel Imports on Market Prices

The persistence of price discrimination across international markets with falling costs of unofficial importing is both paradox and policy concern. E-commerce facilitates a “grey” market in parallel imports, particularly for high-value goods such as electronics. This paper explores the impact of unofficial imports on price using a panel of product markets mediated via an Internet shopbot. It finds the presence of an import model lowers prices across the market. However, unlike the refurbished model it is not simply an inferior substitute. The import price discount increases over the model life cycle, suggesting that model-specific preferences fall as each model ages.

R&D competition, absorptive capacity, and market shares

This paper deals with an oligopolistic industry where firms are engaged in cost-reducting R&D activity to maximize their market shares. The existence and uniqueness of a feedback-Nash-optimal R&D strategy for each firm are discussed. Our simulations highlight that variations in spillovers hardly influence the firms' R&D investment, if their absorptive capacities to exploit extramural knowledge depend on their R&D efforts. Moreover, extramural knowledge cannot completely replace in-house R&D. However, a high level of public R&D favors the firm with the most restrictive R&D expenditure constraint and/or with the lowest initial R&D stock, provided it invests in R&D.
