Considering the expansion of research output across the globe, along with the growing demand for quantitative tracking of research outcomes by government authorities and research institutions, the challenges of author identity are increasing. In recent years, a number of initiatives to help solve the author “name game” have been launched from all areas of the scholarly information market space. This article introduces the various author identification tools and services Thomson Reuters provides, including Distinct Author Sets and ResearcherID—which reflect a combination of automated clustering and author participation—as well as the use of other data types, such as grants and patents, to expand the universe of author identification. Industry-wide initiatives such as the Open Researcher and Contributor ID (ORCID) are also described. Future author-related developments in ResearcherID and Thomson Reuters Web of Knowledge are also included. 相似文献

Twenty-first century students need consideration, ideas, and face-to-face work to enable their success in acquiring new information. Twenty-first century skills are generally described as core competencies such as collaboration, digital literacy, critical thinking, and problem solving. Collaborative work between the classroom instructor and the librarian builds digital reference and research materials to follow a scaffolded research project specifically from start to finish. This article identifies reference opportunities and the importance of online and face-to-face student support. Instead of a linear approach to information literacy, this article demonstrates a chunked eLearning in-context performance support style. 相似文献

President Reagan's success stems from his use of rhetorical structures characteristic of the oral epics and his use of the electronic media which partially replicate conditions characteristic of preliterate oral societies. These societies develop a culture transmitted orally through epic poems or recitations. Such recitations are developed by themes, formulas, and repetition as well as by distinctive thought patterns, experiential and non‐analytic. Reagan's methods will have a lasting influence on American political discourse, since future politicians will emulate his techniques. 相似文献

This article examines parental regulation of children and teenagers' online activities. A national survey of 1511 children and 906 parents found that 12–17-year-olds encounter a range of online risks. Parents implement a range of strategies, favoring active co-use and interaction rules over technical restrictions using filters or monitoring software, but these were not necessarily effective in reducing risk. Parental restriction of online peer-to-peer interactions was associated with reduced risk but other mediation strategies, including the widely practiced active co-use, were not. These findings challenge researchers to identify effective strategies without impeding teenagers' freedom to interact with their peers online. 相似文献

This essay argues that there is far too little research on the effects of new types of media programming and formats on children. In fact, the gap between the research base and production and policy issues appears to be widening. The essay advocates use of the developmental research model to study media effects on children. More specifically, researchers should focus more on the neuropsychological effects of format characteristics and viewing styles of children. 相似文献

Although sweeping statements about the effect of television viewing on political participation could still be found in the literature in the 1990s, it is now commonly held that the effect of television should be studied as a multidimensional phenomenon. Not only the time spent watching television but also the kinds of programs being watched and even the preference for particular stations are assumed to have an effect. In this article, we report on a survey among 6,330 Belgian adolescents allowing for a comprehensive analysis of the relationship between various dimensions of television viewing and political participation. We focus on adolescents, because research suggests that the decline in participation levels clearly manifests itself in this age group. The results of the analysis confirm a negative impact of the amount of television viewing, which is partly counterbalanced by a positive impact of a preference for information and for public broadcasting. We discuss the implications of these findings among adolescents for adult participation behavior. 相似文献

The use of problem-solving strategies by 59 deaf and hard of hearing children, grades K-3, was investigated. The children were asked to solve 9 arithmetic story problems presented to them in American Sign Language. The researchers found that while the children used the same general types of strategies that are used by hearing children (i.e., modeling, counting, and fact-based strategies), they showed an overwhelming use of counting strategies for all types of problems and at all ages. This difference may have its roots in language or instruction (or in both), and calls attention to the need for conceptual rather than procedural mathematics instruction for deaf and hard of hearing students. 相似文献

A total of 104 six-year-old children belonging to 4 groups (English monolinguals, Chinese-English bilinguals, French-English bilinguals, Spanish-English bilinguals) were compared on 3 verbal tasks and 1 nonverbal executive control task to examine the generality of the bilingual effects on development. Bilingual groups differed in degree of similarity between languages, cultural background, and language of schooling. On the executive control task, all bilingual groups performed similarly and exceeded monolinguals; on the language tasks the best performance was achieved by bilingual children whose language of instruction was the same as the language of testing and whose languages had more overlap. Thus, executive control outcomes for bilingual children are general but performance on verbal tasks is specific to factors in the bilingual experience. 相似文献

The Revised Learning Process Questionnaire has been part of the development of a conceptual understanding of how students learn and what motivates them to engage in particular tasks. We obtained responses from 329 student volunteers at a mid‐sized public university in the southeast USA. We first investigated whether the psychometric properties and latent factor structure of this questionnaire are replicable in a different educational context and with students from a different country than that originally used to create and validate the questionnaire. We found this to be true. Second, we used Profile Analysis via Multidimensional Scaling (PAMS) to improve the diagnostic functionality of the instrument as well as further explore the latent structure of the questionnaire. The factor structure was evident in this solution, but we found that interpreting the latent structure in terms of the dimensions of Strategy and Motive as opposed to the factors of Deep and Surface approaches to be more appropriate for diagnostic use. We also found that PAMS has the inherent ability to assess an individual’s fit within the model, thereby acting as a measure of self‐report credibility. The Strategy dimension was found to have ecological validity through analysing its relationship to academic performance. 相似文献
