What happens when educational ideas cross national and cultural borders? How do teachers respond to ideas originating in a different school system and a different national culture? This article reports on an empirical study investigating the transfer of ideas from Design &; Technology as a subject in England and Wales into Norwegian schools. A sample of teachers participating in a specific project on technology teaching inspired by this subject has been studied by means of interviews and classroom observation. Results of the study show that while some elements of Design &; Technology are adopted by the teachers, essential ideas of the subject are significantly transformed. Drawing on Barnes, (1992, Teachers and Teaching: From Classrooms to Reflection (pp. 9–32), The Falmer press, London) concept of teachers' professional frames for teaching, it is shown how specific aspects of the national and educational culture have had a considerable effect on?the teachers' interpretation of the nature of technology as a subject of teaching and its place in the curriculum. The study illustrates the importance of the cultural context in how educational ideas are interpreted, reshaped and realized in schools. 相似文献

英国是欧洲风险投资和非公开权益资本的发源地。在欧洲国家中,英国的风险投资和非公开权益资本起步最早,发展也最快。从1979年算起,英国风险资本投资额和非公开权益资本增长了100多倍。2005年,在欧洲的风险投资市场上,英国的风险资本总额占欧洲风险投资额的40 ̄50%,在欧洲是当仁不让的“大哥大”,在世界范围内仅次于美国。本篇文章主要介绍了风险投资(VentureCapital,VC)及非公开权益资本(PrivateEquity,PE)的最新概念和从属关系以及英国的风险投资及非公开权益资本的历史、结构、规模、投资趋势、投资阶段、投资领域、地理特征、知名风险企业、投资表现等,以此从数据和分析的角度使中国的风险投资领域及非公开权益资本领域的从业人员以借鉴、启迪的作用。 相似文献

This paper documents evidence on the efficacy of maturity-gap disclosures of commercial banks in indicating their net interest income that is exposed to interest-rate risk. For the large sample of banks that filed call reports from 1990 to 1997, a period that includes a wide range of interest rate movements, we find that (i) one-year maturity gap measures are significantly related to the one-year- and three-years-ahead change in net interest income, (ii) fixed-rate and variable-rate instruments differ in explanatory ability, and (iii) the one-to-five-year aggregate gap measures also have some power in explaining three-year-ahead changes in net interest income. These findings hold after controlling for the ex post growth in assets as well as the amount of rate-sensitive assets and liabilities (a competing set of explanatory variables). Because the Securities and Exchange Commission (SEC)'s [Securities and Exchange Commission (SEC), (1997). Disclosure of accounting policies for derivative financial instruments and derivative commodity instruments and disclosure of qualitative and quantitative information about market risk inherent in derivative financial instruments, other financial instruments, and derivative commodity instruments. Release Nos. 33-7386; 3438223; IC-22487; FR-48; International Series No. 1047; File No. S7-35-95 (January 31, 1997), Washington, DC] tabular disclosures are finer than maturity-gap data, our findings mitigate concerns about the usefulness of the SEC's market-risk-disclosure requirements. Furthermore, they suggest contrary to the claims of certain banks that the omission of prepayment and early withdrawal risk from gap measures does not totally compromise the ability of gap data to indicate interest-risk exposures. 相似文献

This paper examines takeover and divestiture activity at the industry level for the population of UK firms over the period 1986–2000. Consistent with US research, takeovers in the UK cluster both across industries and over time. The evidence for divestitures indicates clustering across industries only. The paper further investigates whether broad and specific industry shocks (e.g., growth, free cash flow, concentration, deregulation, foreign competition, technology, stock market performance) explain takeover and divestiture clustering at the industry level. The results suggest that broad shocks increase (decrease) the likelihood of takeovers (divestitures), although not significantly for takeovers. Specific industry shocks that increase the likelihood of takeover activity include low growth, the threat of foreign competition and high stock market performance. For divestitures, high industry concentration and deregulation increase activity. Little evidence is found for deregulation as a significant factor in explaining takeover activity. 相似文献

The average cost of a sales call has declined approximately 15% over the past decade, while average salesperson compensation has doubled. These statistics illustrate an important benefit of technology: salespeople are more productive. To better understand the impact technology has played on sales and sales management, this paper examines the impact of sales technology from four perspectives: the salesperson, the field sales manager, the sales executive, and the customer. Noting that the needs and evaluations of technology vary, depending upon the functional position and viewpoint, a research agenda is offered that reflects these various perspectives. 相似文献

The adoption of information technology in the sales force 总被引:1,自引:0,他引:1

The purpose of this article is to explain why salespeople adopt information technology. The results from a cross-sectional study of 229 salespeople indicate that putting sales technology to use strongly depends on salespeople's perceptions about the technology enhancing their performance, their personal innovativeness and organizational efforts in terms of user training. Throughout the adoption process companies also need to target sales line managers-next to end users-because salespeople clearly comply with the expectations of their supervisors. Finally, the threat from competing sales professionals or peers who use similar sales technology seems to be of secondary importance for individual sales technology adoption. 相似文献

To our knowledge, this research is the first to focus on the critical moderating role that user training and support play on the relationship between the use of sales force automation tools and salesperson performance (i.e., effectiveness: percent-to-quota and efficiency: average number of calls per day). Hypotheses are tested using survey data from a sample of 108 salespeople in a business-to-business context and archival sales performance information. Moderated regression analysis results indicate that the use of sales force automation tools only enhances salesperson efficiency and effectiveness under conditions of adequate user support and training. In fact, under low levels of user training and support, the use of sales force automation tools was found to reduce salesperson efficiency and effectiveness. These findings have important implications for IT and sales managers since the results show that only under certain conditions will companies realize a return on their investment in SFA tools. Limitations and future directions for research are then discussed. 相似文献

The impact of population growth and climate change on food security in Africa: looking ahead to 2050
Providing nutritious and environmentally sustainable food to all people at all times is one of the greatest challenges currently facing society. This problem is particularly acute in Africa where an estimated one in four people still lack adequate food to sustain an active and healthy life. In this study, we consider the potential impact of future population growth and climate change on food security in Africa, looking ahead to 2050. A modelling framework termed FEEDME (Food Estimation and Export for Diet and Malnutrition Evaluation) was used which was characterized to model the impacts of future climate changes (utilizing the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios projections) and projected population growth on food availability and subsequent undernourishment prevalence in 44 African countries. Our results indicate that projected rapid population growth will be the leading cause of food insecurity and widespread undernourishment across Africa. Very little to no difference in undernourishment projections were found when we examined future scenarios with and without the effects of climate change, suggesting population growth is the dominant driver of change. Various adaptation options are discussed, such as closing the yield gap via sustainable intensification and increasing imports through trade and aid agreements. These strategies are likely to be critical in preventing catastrophic future food insecurity. 相似文献
