The compact disk (CD) player was one of the major audio innovations of the 1980s in the Netherlands. For studies of the temporal and social diffusion pattern of the CD player and the compact disks, both cultural and economic theories about innovations and music consumption are available. In this paper, these theories are combined in six working hypotheses concerning earlier adoption. The empirical analysis includes both time-invariant and time-varying variables and consumer characteristics. Event history analysis, the technique used in this article, enables one to incorporate these kinds of variables simultaneously in a dynamic model. Compared with the diffusion models usually employed by means of longitudinal analysis, event history analysis is a significant improvement in studying the development of the CD market in the Netherlands. 相似文献

For self-regulated learning to be effective, students need to be able to accurately assess their own performance on a learning task and use this assessment for the selection of a new learning task. Evidence suggests, however, that students have difficulties with accurate self-assessment and task selection, which may explain the poor learning outcomes often found with self-regulated learning. In experiment 1, the hypothesis was investigated and confirmed that observing a human model engaging in self-assessment, task selection, or both could be effective for secondary education students’ (N = 80) acquisition of self-assessment and task-selection skills. Experiment 2 investigated and confirmed the hypothesis that secondary education students’ (N = 90) acquisition of self-assessment and task-selection skills, either through examples or through practice, would enhance the effectiveness of self-regulated learning. It can be concluded that self-assessment and task-selection skills indeed play an important role in self-regulated learning and that training these skills can significantly increase the amount of knowledge students can gain from self-regulated learning in which they choose their own learning tasks. 相似文献

The purpose of this article is to explore the intersectionality of autism and sociocultural factors as well as discuss the complexities associated with appropriate assessment, diagnosis, and intervention. Based on a review of the literature, the authors present a brief history of the emergence of the term autism and highlight factors that have contributed to current concerns about failures to appropriately recognize autism within diverse populations. Referencing extant research as well as professional practice standards, this article examines aspects of autism and intersectionality, and explores some of the associated challenges related to assessment, diagnosis, and intervention. Further, the authors reflect on the critical importance of carefully considering all aspects of a child's identity when engaging in autism assessment and intervention within the school setting. School-based practitioners are provided with guidance for addressing the needs of diverse populations of students with autism. 相似文献

Large scale statewide library cooperation using information technology and wide area networks dates back to the early 1980s with efforts such as the Florida Center for Library Automation and, more recently, the LOUIS Project in Louisiana (see JAL January 1994) and OhioLink (see JAL September 1995). Early efforts were usually focused on the implementation of library information management systems and the provision of shared access to locally held collections, and they often still are. In the 1990s, though, we are witnessing a shift in statewide cooperative use of networks to provide principally access to bibliographic and full-text resources not held locally and usually provided by commercial vendors for use by libraries. As the case studies in this column illustrate the development of funding sources, the technical implementations and support, and the management organization differ from state to state. They reflect, though, the incremental shift in the information landscape towards “electronic libraries”. I choose the word incremental intentionally to reflect that this change has not (at least so far) been anywhere near as rapid or revolutionary as many expected. Nevertheless, what has happened in about 15 years is quite dramatic. It portends a different kind of academic library.—CBL, University of Maryland, College Park. 相似文献
