The innovation–economic growth nexus: Global evidence     

Iftekhar Hasan  Christopher L. Tucci 《Research Policy》2010,39(10):1264-1276

This paper extends the line of research attempting to link innovation to economic growth by addressing some unexplored questions. Using global patent data, this paper empirically investigates the importance of both the quantity and quality of innovation on economic growth, controlling for past measures of inventive inputs. Moreover, our research examines how innovation inputs can be translated into per capita growth under the various economic structures and stages of economic development. Based on a sample of 58 countries for the period 1980–2003, our empirical results indicate that countries hosting firms with higher quality patents also have higher economic growth. Furthermore, we have some evidence that those countries that increase the level of patenting also witness a concomitant increase in economic growth.  相似文献

Promising Practices for Providing Alternative Media to Postsecondary Students with Print Disabilities     

Gerri L. Wolfe  Christopher Lee 《Learning disabilities research & practice》2007,22(4):256-263

For postsecondary students with disabilities influencing reading performance, printed class materials pose a substantial barrier and have a negative impact on academic achievement. Digital technologies offer alternative ways of accessing print materials for students with print‐related disabilities. Alternative media is a broad term that encompasses a variety of formats into which printed text is converted. Alternative media, together with assistive computer technologies designed to read aloud the text, provide a means to access textual information and bypass the difficult reading process. The purpose of this article is to provide an overview of model programs and pertinent research on the use of alternative media by postsecondary students with print disabilities; we will identify promising practices for students whose disabilities negatively influence reading performance.  相似文献   

Why young elite athletes fear failure: consequences of failure   总被引：1，自引：0，他引：1  

Sagar SS  Lavallee D  Spray CM 《Journal of sports sciences》2007,25(11):1171-1184

Fear of failure can have negative effects on children in achievement settings, affecting many aspects of their lives. Perceiving the consequences of failure to be aversive provides the basis for fear of failure, and the anticipation of a threatening outcome elicits fear. Problems attributed to fear of failure in achievement settings are prevalent. Sport is a popular and significant achievement domain for children and adolescents and there is a lack of research on fear of failure in sport among this age group. Therefore, the aim of the present study was to investigate fear of failure in the sport domain among young elite athletes, and to explore their perceptions of the consequences of failure. Interviews were conducted individually with nine athletes aged 14 - 17 years (5 males, 4 females). Analysis identified and organized perceived consequences of failure into themes and categories. Results revealed that the most commonly perceived aversive consequences of failure were diminished perception of self, no sense of achievement, and the emotional cost of failure. These findings are consistent with those reported in adult population, suggesting the potential for generalizing existing results to young elite athletes.  相似文献
