Early career researchers (ECRs) are of great interest because they are the new (and biggest) wave of researchers. They merit long and detailed investigation, and towards this end, this overarching paper provides a summary of the first‐year findings of a 3‐year, longitudinal study of 116 science and social science ECRs who have published nearly 1,200 papers and come from 7 countries and 81 universities. ECRs were interviewed in their own languages face‐to‐face, by Skype, or telephone. The study focused on the attitudes and behaviours of ECRs with respect to scholarly communications and the extent to which they are adopting new and disruptive technologies, such as social media, online communities, and Open Science. The main findings include: publishing in high‐impact factor journals is the only reputational game in town; online scholarly communities, and ResearchGate in particular, are gaining ground; social media are beginning to have an impact, especially in the dissemination arena; outreach activities have become more important; libraries are becoming increasingly invisible to ECRs; Open Science is not gaining traction; and more transformational ideas are being expressed, especially in the US and UK. 相似文献

To explore the citation evolution of papers published in the same year but different month, we selected papers from a discipline (physical geography), a subject (diabetes: endocrine and metabolism) and a journal (Journal of Biological Chemistry) published in 2005 as research objects. These papers were divided into six groups according to the difference in publication month, and we analyzed citations to these papers for the 9 years after publication. The results showed that within 5 years after papers from physical geography were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); after that, the differences were not statistically significant. Within 5 years after papers from diabetes (endocrine and metabolism) were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Within 7 years after papers from the Journal of Biological Chemistry were published, the overall differences in citations of papers in different groups were statistically significant (P < 0.05); thereafter, the differences were not statistically significant. Citations of papers followed the same pattern irrespective of discipline, subject or journal: citations of papers published in the same year but different month were obviously different in the first few publishing years, but as time went on, only the difference in publication month in a calendar year did not affect the papers' longer‐term citation. 相似文献

The aim of the present study was to examine the spelling development of Greek‐speaking children in the early school grades. Although Greek orthography is regular for reading, it is much less transparent as far as spelling is concerned. Spelling development was investigated using a word spelling task designed to explore the effects of word length, familiarity and spelling regularity. One hundred and fifty normally developing primary school children living in Cyprus took part in the study. Results suggest that the children employed both phonological and lexical strategies in spelling Greek words. Results indicated that sub‐lexical procedures were more marked for younger children, whereas lexical processing was employed more widely by older children. The findings are interpreted in terms of stage developmental models. 相似文献

From the perspective of the Fuzzy Trace Theory, this study investigated the impacts of concept maps with two strategic orientations (comprehensive and thematic representations) on readers' performance of cognitive operations (such as perception, verbatim memory, gist reasoning and syntheses) while the readers were reading two history articles that argue from different perspectives about a historical incident that had a profound impact on Taiwan. The results show that the design and focus of the concept maps may influence the formation of mental representations, and that this may be facilitative or constraining in regard to the readers' memory formation and reasoning about the reading materials. Based on these findings, the meaning of constraining effects of concept maps is discussed, and an instructional method involving the progressive elaboration of concept map systems is recommended. 相似文献

A formal model of the scientific communication process is presented using the IDEF0 notation. The model provides a roadmap for policy discussions and further research. In comparison to earlier models it is more detailed and hierarchical, and includes more modelling constructs. It includes the whole communication value chain, from initial research to the assimilation of research results to everyday practice. Although the model treats both informal and formal communication, as well as the publishing of data, its focus is on modelling the publishing and indexing of traditional peer‐reviewed journal articles, and finding and retrieving them. New developments enabled by the Internet, such as open access journals and e‐print repositories, are also included. 相似文献

The programme of the Département de la Formation Internationale at Ecole Nationale des Ponts et Chausées (ENPC) was created in 1981 to address the ever‐increasing international role of today's engineer in the scientific, economic and social spheres. Each year, 75 ENPC students spend at least 3 months abroad, mainly in Europe. ENPC has double degree programmes in engineering studies with three European partners in Germany and Spain: TU Munich and TU Berlin; Universidad Politécnica de Madrid. Twenty per cent of the student curriculum is devoted to language study; the students are required to study English plus one of the following languages: German, Spanish, Italian, Russian, Japanese or Chinese. French courses for foreign students are also provided. Language teaching aims to provide students not only with the linguistic skills necessary for communication, but also to make them more sensitive to other cultures as well as their own. 相似文献

During economic development, modern museums face competition from various leisure activities and entertainment sites, and to achieve sustainable development, museums should reflect on providing high‐quality service to satisfy visitors’ expectations. Based on service design‐related theories, this research team conducted a case study to explore the planning, implementation, and meaning of Mobile Museums. It investigated design development from the perspective of public service design and summarized the policy, design, and service satisfaction results for Mobile Museums. Finally, the similarities in service processes are discussed between Mobile Museums and the general service industry. According to this study, attracting more visitors is the biggest issue facing museums today, as are the ways in which museums must actively provide service and become recognized to compete with others. This study identifies the onstage and backstage support of museums as well as their cultural features and non‐profit services. 相似文献
