This article surveys the current copyright situation, and the changes that have recently taken place, or which are still under discussion, to take account of the new challenges of the digital environment. A suggested hierarchy of prime and subsidiary electronic rights is outlined, and some significant developments in both licensing and electronic rights trading are discussed. Publishers and authors are urged to find new ways of licensing in the digital environment, if they are to avoid an environment of ‘limitations, exceptions and compulsory licensing’, which would not be conducive to a flourishing digital economy.  相似文献

Cognitive engineering has led to a consideration of the capabilities and limitations of users in relation to the products of system design. However, there has not been a similar recognition of human limitations in the process of design. One way to improve the products of system design is by making improvements in the process of design and, in particular, by addressing the limitations of designers through scaffolding with the technology that is the object of design. To do this we need to identify what we know about the process of designing for computer-mediated learning systems, and to build an understanding of how the design process might benefit from cognitive strategies and computer technology. Here we survey various approaches to support the design process, in order to identify approaches and opportunities that may inform both fields. Specific suggestions include heuristics for design, and scaffolding the design process through support tools. © IFIP, published by Kluwer Academic Publishers  相似文献

Grit has been defined as passionate perseverance toward long-term challenging goals and it is associated with various positive outcomes for youth, including academic achievement. However, less is known about these associations for the two facets of grit (i.e., perseverance of effort, consistency of interest) and few studies have examined the link between grit and perceived social support. The present study examined the group-level demographic differences (i.e., gender, grade, socioeconomic status, and special education status) of grit in a high school sample (N = 1,077). In addition, direct associations between grit and perceived social support from multiple sources (i.e., teacher, classmate, parent) were examined, as well as a potential enhancing effect of social support as a moderator of the relation between grit and academic achievement. Results indicated positive associations among grit and its facets with social support from parents and classmates. Furthermore, the positive relation between grit and achievement was stronger for students reporting high social support from teachers, but not other sources (i.e., classmates, parents). Practical and theoretical implications for promoting student success are discussed.  相似文献

An understanding of the uses of metacognition provides a powerful tool toward developing quality and efficiency in task learning and performance. Metacognition is the executive controller of cognitive processes responsible both for self regulated learning and work performance outcomes. Comprehension monitoring and motivation are two prime components of metacognition which are responsible for commitment to, and definition of, goals, monitoring progress toward goals, and activating the appropriate thinking skills to achieve goals. Specific thinking skill categories of attention, organization, and elaboration are described with examples of how specific techniques in each category can optimize learning and job performance. Research on training of metacognitive skills through both detached and embedded skill-development programs is reviewed. In addition, ways to compensate for metacognitive skills when training is not cost-effective are described. The relationship between metacognitive skills and effective management of work performance is stressed.  相似文献

A meta‐analytic review of all adequately designed field and laboratory research on the use of incentives to motivate performance is reported. Of approximately 600 studies, 45 qualified. The overall average effect of all incentive programs in all work settings and on all work tasks was a 22% gain in performance. Team‐directed incentives had a markedly superior effect on performance compared to individually‐directed incentives. This effect was not influenced by the location of the study (business, government, or school), the competitive structure of the incentive system (programs where only the highest performers get incentives versus programs where everyone who increased performance receives incentives), the type of study (whether the study was a laboratory experiment or a field study), or the performance outcome (quality, quantity, or both). In these studies, money was found to result in higher performance gains than non‐monetary, tangible incentives (gifts, travel). More research is needed on the relative cost‐benefit of cash and gift incentives, and the way different types of tangible incentives are selected. Long‐term programs led to greater performance gains than shorter‐term programs did, and somewhat greater performance gains were realized for manual than for cognitive work. Explanations based on cognitive psychological principles accompany each of the analyses.  相似文献
