对大学英语教学中多媒体技术的回顾与反思

20世纪90年代末,随着高校扩招,现代教育技术在大学英语教学中的应用如火如荼.其中,PPT(Power Point)课件因其充满趣味性和互动性受到广大英语教师的青睐,成为大班授课的有效手段,也是读写教学中主要采用的多媒体教学方式.经过十年探索,多媒体课件的弊端已在教学中完全显现出来,回到传统教学的趋势已是必然.从传统教学到现代化教学再重新拾起传统教学,这种否定之否定已经超越了从前的传统教学模式,不应再是简单的回归.纵观20世纪电化教学手段的变迁,每个英语教师都应当以最佳教学效果为原则,灵活应用现代教育技术.     

Performance,Representation and the Economics of Border Control in Uzbekistan

This article explores the contradictions and intersections between the performative and economic aspects of state boundary control. From 1999 onwards, Uzbekistan's formal trade with its neighbours declined dramatically, whilst cross-border smuggling mushroomed. This article examines these developments, using both an economic analysis, and a theoretical approach to the study of international boundaries derived from political geography, anthropology and ‘borders theory’. Methodologically, it employs trade-flow analysis, discourse study and ethnography to construct an account of how an apparently economically counterproductive policy has symbolic and performative value to the state. The changes in trade patterns were largely due to the unilateral introduction of a new and highly disruptive border and customs control policy, which dramatically increased transportation costs, precipitating a growth in smuggling in which some state officials themselves colluded. Economically, whilst this policy would thus appear harmful to the state, the article suggests that border control policies also had a theatrical function related to the performance of national identity and the perpetuation of the incumbent regime. It concludes with policy recommendations addressed to both Central Asian states and international donors.     

Multiple Levels of Culture and Post M&A Integration: A Suggested Theoretical Framework

A substantive body of research suggests that cultural differences represent impediments to merger and acquisition (M&A) integration. Yet current findings on the subject differ in terms of the impact of cultural differences. To date, M&A research has failed to capture the diversity of cultural influences that affect merging organizations. This conceptual article addresses this theoretical gap. Its purpose is to suggest a theoretical model of the culture‐integration relationship. This model helps explain the inconsistent results of previous studies, and provides challenging opportunities for future research. © 2013 Wiley Periodicals, Inc.     

Research Opportunities Related to Consumer Response to Product Design*

This essay identifies five research opportunities that concern consumer response to product design. The first opportunity involves the need for more research on the interaction between form and function in consumer product evaluations. To this end, more knowledge about how product appearance characteristics influence consumer evaluation of both product form and function, and how this differs between countries and in time, is needed. The second research opportunity concerns the influence of consumer input in the front end of new product development on product success. Although the positive effect of market information use on product success is known, more actionable insight into which consumer information or input is beneficial in which circumstances is largely missing. The third opportunity for research concerns how to include subjective product attributes in concept testing. Getting valid feedback from consumers, which includes functional as well as emotional and experiential aspects, can improve proficiency in the early stages of product development. In this essay, several ways of approaching this research endeavor are highlighted. Next to enhancing market receipt and the assessment of product design, two topics that concern consumer response to product design from a more managerial viewpoint are identified. The first of these is strategic management of product styling. The importance and opportunities of visual design for brand management has gained more attention in the literature; different strategies and the cases in which they are beneficial are issues for further research. And finally, the design of product service systems (PSSs) provides opportunities for future research. Here, engendering perceptual unity between products and services and an explicit managing of meanings and feelings that PSSs should communicate are issues at play.     

Value for value—The dynamics of supplier value in collaborative new product development

Suppliers are recognized as an important source of innovation. Research into supplier involvement in new product development has shown that benefits can potentially be reaped by customers. However, a relatively unexplored precondition is the willingness of suppliers to invest in their customers’ innovative efforts. In this exploratory, theory-extending research, we investigate the value that a supplier can experience from being involved in high tech firms’ new product development. We find that value comes in three forms for suppliers: (1) financial payment for sales volumes and product development services, (2) technological knowledge and product designs, and the (3) reputation of doing business with leading-edge firms Additionally, we place this in a dynamic, long-term perspective, and find indications for a positive or negative feedback effect, depending on the emphasis the buyer puts on collaborative innovation with the supplier and the extent to which suppliers can use competences, knowledge and reputation resulting from the collaboration in subsequent business development activities. The positive effect results in added value for both parties in the dyad, and the negative effect leads to the opposite.     

Tactical allocation in commodity futures markets: Combining momentum and term structure signals

This paper examines the combined role of momentum and term structure signals for the design of profitable trading strategies in commodity futures markets. With significant annualized alphas of 10.14% and 12.66%, respectively, the momentum and term structure strategies appear profitable when implemented individually. With an abnormal return of 21.02%, our double-sort strategy that exploits both momentum and term structure signals clearly outperforms the single-sort strategies. This double-sort strategy can additionally be utilized as a portfolio diversification tool. The abnormal performance of the combined portfolios cannot be explained by a lack of liquidity, data mining or transaction costs.     

Proposition for an improved version of the consumer entitlement inventory

This note proposes an improved version of the Consumer Entitlement Inventory (CEI) developed by Boyd and Helms ( 2005 ). Two studies, conducted in two different cultural settings—France (n = 203) and the United States (n = 181)—raised some issues with the original version of the CEI. The underlying theoretical reasons for these results are discussed and an analysis of the CEI's content validity is performed. An improved version of the CEI, enriched with items that more closely capture the consumer entitlement construct, is proposed. © 2010 Wiley Periodicals, Inc.
