Theodore Lewis 《International Journal of Technology and Design Education》1996,6(3):221-238
British and American discourses and experiences with respect to technology education are compared. Out of this comparison important issues are identified that have implications for the larger ongoing conversation on technology beyond these countries. They include the role of the state in establishing and validating the subject, the dual claims of technology literacy and technological capability, and dual curricular approaches — content and process. 相似文献

The focus of this study is to examine different factors that influence a firm's technology cycle time. The U.S. pharmaceutical industry is analyzed from 1977–1991. Specifically, the sample includes 21 firms that (a) primarily produce brand ethical drugs, (b) are publicly-owned companies, and (c) have pharmaceutical sales account for a substantial portion of company sales.
Our measure of faster technology cycle time is positively correlated to measures of the knowledge base level of firms, the breadth of firms' knowledge bases, size, and age; it is negatively correlated to advertising expenditures and the percent of US. firm sales to total sales. However, the most notable finding is that technology cycle time is significantly faster for firms that predominantly generate new knowledge internally, and slower for firms that rely more on external sources of new knowledge. 相似文献

The upgrade of legacy infrastructure is a challenging undertaking in general. The underlying issues are especially prominent for telecommunications networks outside of urban areas. Using German micro-level data, we identify the structural determinants for fiber optics deployment and its extent. We also measure the role of technology competition from the existing infrastructures, VDSL-Vectoring and TV-Cable. In this setting and exploiting a natural experiment, a technologically restrictive policy as proposed by the European Commission is found to be ineffective in promoting fiber deployment. Policy interventions in the form of subsidies targeted at specific local infrastructure projects, however, raise the likelihood of fiber deployment by a substantial margin. A targeted, proactive policy approach is therefore needed to overcome structural and geographical disadvantages. 相似文献

The development and commercialization of advanced technologies will depend increasingly on efficient technology transfer and technology trading systems. This requires the development of technology markets or exchanges and hence a reliable technology valuation methodology. This paper develops a methodology for an objective and impartial valuation of fully developed technologies.
A web-based technology valuation system is developed with which interested users can make efficient and real-time evaluations of technologies. 相似文献

你被技术改变了多少?你成了技术的一部分吗?你在利用技术还是技术在利用你?说了一年别人的商业故事,2012的最后一期"末日号",我们来谈谈"技术与你"。你已经被技术改变了多少?你成了技术的一部分或是附属品吗?你在利用技术还是技术在利用你?别误会,千万别以为我们是在说技术哲学——那些丰富高深的各类研究技术与人类社会发展关系的理论学 相似文献

Technology has long been recognised as a task-centred activity, but far too little work has been done to understand the nature of tasks and how they operate as teaching and learning tools. The problems surrounding Attainment Target 1 (AT1) in the national curriculum in England and Wales provide ample evidence of this. This paper explores — both in principle and through empirical research data — two central features of tasks ie pupil autonomy/teacher control and the role of the client or user of the end product. Very contrasting views about tasks emerge from the four key stages. 相似文献
