Foreign patenting in the U.S. has been considered to be a useful technology indicator in comparisons between countries. In order to shed light on this topic, this paper will try to explain foreign patenting in the U.S. by way of data for one country - Norway.A crucial question is what role is played by exports in explaining the foreign patent activity. Is the U.S. patenting just an indicator of the export performance, or is it the other way around; that technology - measured by foreign patent activity - is an important trade explanatory variable.The first part of this paper deals with the relationship between Norwegian U.S. patenting and export to the U.S. by way of time-series analysis on data from 1883 to 1980. Then some more detailed analysis are done on industry-level data from 1920 and from 1960–1980. An hypothesis is further tested for the possible relationship between foreign U.S. patenting and the international business-cycles. Finally a detailed but tentative analysis is done on firm-level data for the years 1969–1980.The results lend partial support to the assumption that foreign U.S. patent activity reflects innovative activity in the country where the patents originated. A major advantage in using foreign patenting in the U.S. as a technology indicator, is that this type of data in general seems to be of a higher quality than domestic patent data. 相似文献

This paper integrates the contributions from different branches of the technology transfer literature to identify enablers driving the transfer of intermediate or appropriate technologies to recipients in rural areas of developing economies. An in-depth analysis of the literature shows that many enablers identified in the literature focus on high technology transfers and are of limited relevance in the context of rural enterprises. Other important enablers in this specific setting are ignored or insufficiently considered. This paper proposes a framework comprising a specific set of enablers that facilitates technology transfer in rural enterprises in developing regional economies. 相似文献

Structured talent identification and development, it has been argued, is one of the foundations of international sporting success and many modern elite sport systems have applied normative talent development (TD) models. The success of Norwegian handball, however, is based on an alternative approach to TD. Norwegian handball is characterized by a heterarchical organizational structure in which several key actors function highly autonomously. The aim of this article is three-fold: (a) to describe the organization of TD in Norwegian handball, (b) to identify how the inherent organizational characteristics of Norwegian handball have influenced the TD processes used and (c) to discuss if contemporary TD models provide an adequate conceptualization of the model used in Norwegian handball. This case study includes three units of analysis: (i) the overall organizational structure of Norwegian handball, (ii) the characteristics of the key actors involved and (iii) the inter-communication and collaborations of the key actors. The data sources were (a) documents and (b) interviews with 11 key informants. The informants were selected strategically to represent experienced coaches and professionals from multiple organizational units. The National Handball Federation uses a broad-based model for TD: 23% of male handball players and 15% of female handball players from the age of 13–17 years participate in regional-level initiatives in addition to practising daily in community-based volunteer sport clubs and sport schools. Findings reveal that the broad base of TD initiatives creates multiple access points to the talent pipeline for adolescents. However, because the heterarchical structure involves many actors, the unintended consequences are often related to (im)properly managing training and competition loads. There is a need therefore for well-developed coordination mechanisms and good communication between the key actors involved. 相似文献

The current study examines the developmental trajectory of banging movements and its implications for tool use development. Twenty (6‐ to 15‐month‐old) infants wore reflective markers while banging a handled cube; movements were recorded at 240 Hz. Results indicated that through the second half‐year, banging movements undergo developmental changes making them ideally suited for instrumental hammering and pounding. Younger infants were inefficient and variable when banging the object: Their hands followed circuitous paths of great lengths at high velocities. By 1 year, infants showed consistent and efficient straight up‐down hand trajectories of smaller magnitude and velocity, allowing for precise aiming and delivering dependable levels of force. The findings suggest that tool use develops gradually from infants' existing manual behaviors. 相似文献

Abstract In the late 60s and early 70s, several universities were set up in various European countries with the intention of providing an alternative to established institutions of higher education. The new universities were expected, amongst other things, to experiment with new forms of leadership and management internally, give teaching and learning higher priority, and to be regional relevant institutions for the area in which they were located. The paper analyses to what extent three such university establishments: Aalborg University in Denmark, Maastricht University in the Netherlands and Troms?University in Norway have managed to maintain and develop their alternative profile during the last thirty years. The study suggests that even though the universities in some areas have adapted to environmental pressure, they have managed to keep their profile as innovative and alternative. 相似文献

The important role in learning and upbringing played by teachers has been acknowledged for a long time. However, research on this question belongs with few exceptions, to the post‐war area in all the Nordic countries. During the last few decades a extensive research within a variety of studies have addressed the question. And, in accord with realistic expectations, the research conducted within this area since the middle of the 1950ties reflects a change in the interest of researchers similar to that found outside the Nordic countries, from studies of teacher behaviour to research on teacher cognition and analyses of the interactions between students and teachers in the classroom. The review also reveals a clear and significant change in the use of research methods: quantitative methods have declined while qualitative methods have expanded. It seems characteristic of research within this area that a great number of studies have been explorative in nature and that few of them have been followed up by more intensive and theoretically grounded research. It is the authors' opinion that, considering the great number of unanswered questions and the importance of solid knowledge of the questions related to teachers' qualifications and to teacher education, it seems that research within this area is still in its infancy stage. 相似文献

AbstractThis paper reports from a survey of media exposure and level of knowledge among senior high school students at various locations in Indonesia. Government budgets for education have recently been dramatically reduced in Indonesia and increasing financial burdens are put on the households, like in many other poor countries. There is a tendency to increasing differences in quality of schooling among social layers and geographical areas. Main conclusions in this research are that information asymmetry exists as a problem in society and that type of school and location matter more than media exposure for students’ knowledge level. Students in public schools generally score significantly higher than those in private institutions. Also, students’ level of knowledge tends to fall with decreasing level of geographical centrality. Our policy recommendations include increased public investment in quality schooling for all. 相似文献

The Danish e-commerce strategy is a highly ambitious effort to become the world's leading IT nation. Instead of a production-led approach aimed at stimulating domestic hardware and software production, Denmark has pursued a demand-oriented approach focused on promoting the widespread adoption of e-commerce in the Danish society. The Danish government has developed a number of e-commerce initiatives via public-private sector partnerships--an approach we refer to as "governance." So far, it appears that Denmark has been successful in promoting business-to-business (B2B) e-commerce, with a number of Danish companies being global leaders in the use of B2B applications. On the other hand, Denmark has had less success in achieving widespread use of business-to-consumer (B2C) e-commerce. This article analyzes the Danish national environment for e-commerce, discusses four sets of governance initiatives aimed at the development of e-commerce, and analyzes the reasons for its success in B2B and relative failure in B2C adoption. 相似文献

This article reports on a small-scale investigation of how teachers organise goal-oriented learning in Swedish preschools. The revised Swedish curriculum (National Agency for Education 2011) highlights the need for children to develop their mathematics skills through activities that integrate play and learning. This study investigates how different types of activities contribute to children developing their understanding of the concepts ‘half’ and ‘double’. Three preschool teachers participated in a developmental project in which they conduct teaching in accordance with the Variation Theory of Learning. The pedagogical contexts they bring into being reveal important insights for early childhood education. The pedagogical context that can be realised in the planned activities limits or favours the learning process and the success of the theoretical aspirations for the session. This article discusses the idea of ‘teaching’ and how to facilitate conceptual development in a goal-oriented but child-centred practice. The main results show that play is central in early childhood education, and that problem-solving as a means for mathematics education needs to be problematised and used with sensitivity to the children's intentions and perspectives. 相似文献
