The idea of using the internet as a platform to mediate social interactions and learning at different levels has progressively
affirming itself, and this has given rise to a huge number of spontaneous and planned collectives, which are often described
as on-line learning networks. On-line learning networks create value through the combination of content and people’s knowledge.
They can vary widely in the strength and permanence of their connections and the resources necessary to maintain them. Aspects
of both a pragmatic and social nature need to be carefully considered in the process of initiation of on-line learning communities.
This paper considers learning networks from the perspective of the potential they offer to the strengthening of relationships
among institutions, groups, and people sharing a common interest in computer-enhanced learning. Some case studies are analysed
and an analytical framework is sketched out to guide observations and to provide a lens through which case studies can be
interpreted. The final goal is to delineate a reference for identifying strong and weak elements in virtual networks and to
examine under what conditions they are succeeding. In addition, some possible scenarios for on-line networks are delineated
along two main lines: the organisation and structure of the network and its level of establishment.

Over the course of 2018 the University of Sheffield Library conducted a series of interviews and workshops with stakeholders as part of a strategic project to reflect on the value of the university library in the 21st century. Using a mixed methodology, participants were asked to reflect upon the future Higher Education (HE) environment for the university and, for academic participants, their discipline. In this context participants were also asked to reflect upon the future value of the University Library in a series of questions designed to elicit value statements using a tool which the project group have called the ‘Wheel of Value’. The resulting reflections upon the future environment have been grouped into four categories reflecting the drivers for change; Digitalisation, Student Experience, Diversification and Collaboration recognizing that there is considerable overlap and interconnection between these. The reflections on the future value of the library are presented by Wheel of Value higher order categorization. This approach proved useful in eliciting responses from participants in the face of recognized difficulty in getting beyond current views of the library and the approach is recommended to other universities looking to carry out a similar project. The results of this research will be used to inform the development of a view of the library for the purpose of engaging with our university community and key partners. 相似文献

The purpose of the present work is to describe the progression in the conceptions of prospective primary teachers about school
science content while they were participating in three teacher education courses following the same constructivist oriented
strategy. The participants’ written output was analyzed in various categories—selection of content, types of content and their
relationships, levels of complexity, and presentation of content to pupils. There was evidence for some progress in their
conceptions of the content from a traditional view to another that we termed intermediate since it did not reach the vision
that we consider to be the most complex. Finally, we present a General Itinerary of Progression on school content that could
serve as a referent for initial teacher education. 相似文献

Technology transfer should be a central objective of research into educational information technology, as it is generally acknowledged that the quality of this process is a critical factor in effectively bringing about innovation. The central focus of this paper is on this problem. In particular, we discuss the peculiarity of information technology transfer in schools as opposed to the transfer of technology in companies; we indicate some central problems of this transfer and discuss a typology of approaches to the transfer of educational information technology from research to school. 相似文献

The impact upon promotion practices in an inner-city school of a program for the prevention of learning disabilities is examined over a twelve-year period during which the program operated. This preventive approach—a cooperative program of a community school district and a medical center—provided services to identify children vulnerable to learning disabilities, to diagnose the causes of their vulnerabilities, and to intervene educationally in school-based projects. Results of educational intervention are demonstrated in a decrease in nonpromotion rate to 5% or less. 相似文献

Intermittent hypoxia exposure in a hypobaric chamber and erythropoietin abuse interpretation 总被引:1,自引:0,他引:1

The aim of this study was to assess the effect of intermittent hypoxia exposure on direct and indirect methods used to evaluate recombinant human erythropoietin (rhEPO) misuse. Sixteen male triathletes were randomly assigned to either the intermittent hypoxia exposure group (experimental group) or the control normoxic group (control group). The members of the experimental group were exposed to simulated altitude (from 4000 to 5500 m) in a hypobaric chamber for 3 h per day, 5 days a week, for 4 weeks. Blood and urine samples were collected before and after the first and the final exposures, and again 2 weeks after the final exposure. While serum EPO significantly increased after the first [from a mean 8.3 IU x l(-1) (s = 3.2) to 16.6 IU x l(-1) (s = 4.7)] and final exposures [from 4.6 IU x l(-1) (s = 1.4) to 24.8 IU x l(-1) (s = 9.3)], haemoglobin, percentage of reticulocytes, and soluble transferrin receptor were not elevated. Second-generation ON/OFF models (indirect rhEPO misuse detection) were insensitive to intermittent hypoxia exposure. The distribution of the urinary EPO isoelectric profiles (direct rhEPO misuse detection) was altered after intermittent hypoxia exposure with a slight shift towards more basic isoforms. However, those shifts never resulted in misinterpretation of results. The intermittent hypoxia exposure protocol studied did not produce any false-positive result for indirect or direct detection of rhEPO misuse in spite of the changes in EPO serum concentrations and urinary EPO isoelectric profiles, respectively. 相似文献

The rapid expansion of Big Data Analytics is forcing companies to rethink their Human Resource (HR) needs. However, at the same time, it is unclear which types of job roles and skills constitute this area. To this end, this study pursues to drive clarity across the heterogeneous nature of skills required in Big Data professions, by analyzing a large amount of real-world job posts published online. More precisely we: 1) identify four Big Data ‘job families’; 2) recognize nine homogeneous groups of Big Data skills (skill sets) that are being demanded by companies; 3) characterize each job family with the appropriate level of competence required within each Big Data skill set. We propose a novel, semi-automated, fully replicable, analytical methodology based on a combination of machine learning algorithms and expert judgement. Our analysis leverages a significant amount of online job posts, obtained through web scraping, to generate an intelligible classification of job roles and skill sets. The results can support business leaders and HR managers in establishing clear strategies for the acquisition and the development of the right skills needed to leverage Big Data at best. Moreover, the structured classification of job families and skill sets will help establish a common dictionary to be used by HR recruiters and education providers, so that supply and demand can more effectively meet in the job marketplace. 相似文献

In the recent years, several libraries in the United States have been experimenting with Book Industry Standards and Communications (BISAC), the classification system of the book industry, as an alternative to the Dewey Decimal Classification. Although rarely discussed, these cases of implementation of BISAC arguably resemble other past cases of replacement of traditional classifications that received the name of reader-interest classifications. In this article, a comparison of the BISAC cases to the previous cases of reader-interest classifications is taken in order to determine if the current application of BISAC to libraries is susceptible to the same problems, dangers, and ends as occurred in the past. 相似文献

Resilience is an interactive process involving internal skills that should be promoted, especially in the early stages of development. This study aims to adapt and implement two themes from the European Curriculum for Resilience Promotion – RESCUR, namely, ‘Developing Communication Skills’ and ‘Establishing and Maintaining Healthy Relationships’, for deaf and hard-of-hearing (DHH) students. The study included 37 children and adolescents from three Portuguese regions and its impact was evaluated through the perspectives of the students, their guardians and their teachers. Each 90-minute session was implemented weekly. The sessions followed the RESCUR curriculum structure with necessary adaptations to the mindfulness activities, stories, role-play and worksheets. The mean scores increased from pre- to post-intervention assessment on all instruments, namely, KIDSCREEN-10 (children/adolescents), KIDSCREEN-10 (guardians) and CYRM-28 (teachers). The implementation of adapted curricula promoting resilience seems to be beneficial to DHH children, allowing the development of specific resilience-associated skills, and thus enhancing health, well-being and quality of life. 相似文献
