The Commission on Preservation and Access and the Research Libraries Group (both US organizations) created a task force to study the requirements for preserving digital information. The report, published in May 1996, recommends a certification process for digital archives and calls for a legal authority to rescue digital files in danger of being lost. The paper reviews the reactions of the library, archival, and educational communities and describes the current actions being taken. 相似文献

Subsidized research joint ventures (RJVs) between public research institutions and industry have become increasingly popular in Europe and the US. We study the long-run effects of such a support scheme that has been maintained by the Danish government since 1995. To cope with identification problems we apply nearest neighbor matching and conditional difference-in-difference estimation methods. Our main findings are that (i) program participation effects are instant for annual patent applications and last for three years, (ii) employment effects materialize first after one year and (iii) there are no statistically significant effects on value added or labor productivity. We further show that these overall results are primarily driven by firms that were patent active prior to joining the RJV and that there are no statistically significant effects for large firms. The insignificant results we document for large firms coupled with the fact that these type of firms are over-represented in many support programs, including the one considered here, leads us to suggest a rethinking of support policies that often aim at large firms. 相似文献

This article examined longitudinal relations among socioeconomic risk, maternal language input, child vocabulary, and child executive function (EF) in a large sample (N = 1,009) recruited for a prospective longitudinal study. Two measures of maternal language input derived from a parent–child picture book task, vocabulary diversity (VOCD), and language complexity, showed variation by socioeconomic risk at child ages 15, 24, and 36 months. Maternal VOCD at child age 24 months and maternal language complexity at child age 36 months mediated the relation between socioeconomic risk and 48-month child EF, independent of parenting sensitivity. Moreover, 36-month child vocabulary mediated the relation between maternal language input and child EF. These findings provide novel evidence about mechanisms linking socioeconomic risk and child executive function. 相似文献

Despite the rapid growth of online learning in higher education, the dropout rates for online courses has reached 50 percent. Lack of student engagement rank as a critical reason for frequent online course dropout. This article discusses autonomy support as a strategy to enhance online students’ intrinsic motivation and engagement. Drawing from current theories and research, three guidelines are offered to provide choices, rationale behind why assignments are designed in particular ways, and flexibility in completing more personally meaningful assignments. Each guideline is accompanied with examples from existing higher education courses. This article is intended for educators and designers of online learning to employ autonomy support strategies to engage students in active participation and successful completion of the course. 相似文献

17 SK is a community sports club based in Stockholm, Sweden. Its members play different sports, but the football groups are by far the most popular. In this paper, we want to sketch the history of the club and reflect on the aspects of its football activities that seem most relevant from a social and political perspective: gender, integration, community building and matters of organization. We are both co-founders and board members of the club and regularly partake in its activities. The article is therefore mainly based on participatory observation and on numerous discussions we have had with other 17 SK participants over the past three years. 相似文献

Abstract This article describes what happened to an elementary education preparation program when a few faculty members started asking questions, looking at practice, making changes, and collecting data based on the changes. The current program has many outstanding attributes; but when student perceptions were examined, holes were found and ways to mend these holes have been implemented. The authors describe the process of weaving concept Strands throughout the entire four‐year program. 相似文献

As state legislatures and noneducation agents become increasingly involved in regulating the preparation of teachers, the long-term consequences of the resulting policies—which prioritize economic efficiency over investments in the cultivation of a stable, professionalized workforce—are of concern. This article uses insights from political economy to examine the model of teacher preparation that derives from these sources, with particular attention devoted to Indiana's Rules for Educator Preparation and Accountability. 相似文献
