The paper introduces the highly problematic nature of modelling in design and technology education and examines the relationship between cognitive and concrete modelling. Its aim is to gain insight into what learners do, rather than what others say they ought to do in their learning activities. The variety of purposes that educators have for learners’ modelling are discussed through examining the contested curriculum justification for design and technology education itself. The paper proposes that learners’ modelling cannot be extracted from the social milieu in which they act and it provides some insights of these social influences through the analysis of two case studies. Their settings are a girls’ secondary school and a college of higher education. Each case study is presented independently but organised with a common format to consider a) the impact of assessment on learning intentions and outcomes; b) cultural influences on learning and modelling; c) social influences on learning and modelling. A discussion of the emergent themes considers implications for teachers. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

This paper examines the restructuring of the former Soviet economy provoked by the break-up of the USSR and the creation of the Commonwealth of Independent States. Particular attention is devoted to the changes taking place in the former All-Union enterprises that have now essentially become new multinationals. The pressures influencing the two parallel developments of internalization and divestment are examined and illustrated using two case studies. © 1993 John Wiley & Sons, Inc.  相似文献

Integrating design metrics within the early supplier selection process   总被引:2,自引:0,他引:2  
It has been found from the contemporary research in the fields of supply chain management and concurrent engineering that significant benefits can be achieved if suppliers are involved in product development. However, recent investigations in manufacturing industries have revealed that early supplier involvement in the design process is not widely practiced. One issue is the lack of an appropriate customer–supplier interface to assess the suitability of suppliers with reference to design criteria. This paper proposes a mechanism for evaluating supplier involvement during product development. The assessment tool includes four types of distinctive indices to measure supplier involvement in the design process, namely: Satisfaction Index, Flexibility Index, Risk Index, and Confidence Index. These indices measure the extent to which both the customer requirements and the supplier capabilities match or mismatch and therefore reflect the potential or risk of signing a project contract. The proposed methodology is discussed within a multinational telecommunications company and preliminary analysis indicates that the approach provides an effective mechanism for selecting suppliers involved in the product development process.  相似文献

One way for multinationals to manage their exposures to foreign currency fluctuations is by matching the currencies of costs and revenues, a practice sometimes referred to as "natural hedging." Proponents of this risk-management technique argue that matching currencies decreases profit variability.
Using the example of a U.S. firm competing with a French firm for sales in France, the authors analyze the desirability of the U.S. firm's matching currencies of costs and revenues by sourcing in France rather than in the U.S. They find that in such settings with limited competition, while matching reduces profit variability, it also causes a reduction in expected profitability–a potential drawback that appears to have been overlooked in previous discussions.
The authors demonstrate that the U.S. firm, by choosing not to match currencies, retains the strategic flexibility to adjust its prices and quantities in order to exploit the competitive cost differentials caused by exchange rate shifts. The expected profit effects of matching depend on the tradeoff between expected cost savings, if any, of sourcing abroad versus the reductions in expected profits due to the loss of strategic flexibility . They argue that the benefits of strategic flexibility associated with sourcing in the U.S. can yield an increase in expected profits that may outweigh the cost savings and hedging benefits of currency matching.  相似文献

Using 2009 data from the U.S. Energy Information Administration, a study of factors that influence broadband adoption is conducted. The data set includes previously studied demographic factors, as well as records associated with the household’s use of computers, television, pay television services, and broadband. Analysis of the data indicate that, when controlling for a number of demographic factors, the purchase of television services is positively correlated with broadband adoption, with consumers who purchase either cable or satellite television service adopting broadband at a higher rate than those who utilize over-the-air television services. The results suggest that consumers who prefer over-the-air television services may face a more substantial hurdle in broadband adoption, one that might be lowered through the availability of affordable stand-alone broadband services.  相似文献
