Computing postgraduate programmes in the UK and Brazil: learning from experience in distance education
Get PDFEducation can benefit from experiences and collaborations across different countries and cultures. The authors carried out a study to analyse the experiences of the use of Web 2.0 tools in distance education in the UK and propose a set of lessons that can be applied in the Brazilian context. The recent economic growth in Brazil has resulted in a strong demand for further education. Distance education has emerged as a strong contestant to address this demand. The authors present, in this chapter, the case of the provision of postgraduate education for professionals at a distance. Distance education in Brazil is currently gathering support as it offers great potential to address the big geographic and social divides. However, there are many barriers and misconceptions that perpetuate a climate of distrust. Their study draws a set of lessons learned focusing on the benefits that distance education can bring to the development of professional postgraduate education in technical and engineering areas, in the light of the experience of The Open University (OU) in the UK. They emphasise the support that Web 2.0 can bring to these experiences, but also draw attention to the quality that the production process plays in the learning experiences. These lessons address the following: support for skills development with Web 2.0 technologies, the role of the digital educator, open educational resources, open education and social dimension, and quality and pedagogy in the educational process
Cases on Web 2.0 in Developing Countries: Studies on Implementation, Application, and Use
No full textAs the majority of the world continues to move into an internet-based society we have seen significant social, cultural, economic and technological changes. Most developing countries have embraced Web 2.0 and have moved onto the next generation of the World Wide Web, however, some developing countries still struggle to bridge the digital divide. Cases on Web 2.0 in Developing Countries: Studies on Implementation, Application, and Use investigates the perception of the value of Web 2.0, the adoption and application of its technologies, as well as the different approaches and innovations necessary for the implementation of Web applications in developing countries. © 2013 by IGI Global.

Use of the internet in Egypt-A tool to reach or to alter democracy
No full textThe Internet has undoubtedly become an efficient tool in affecting politics in the developed world. Its role was not obvious in developing countries and especially in Arab countries. Recently however, such role has been clearly witnessed with the rise of the Arab spring in general, and in Egypt in particular. During the 18 days of the Egyptian revolution starting on 25th January 2011, and afterwards, the Internet proved to be an important tool in mobilizing people, coordinating between protestors, and documenting and publishing facts that occurred on the ground during the revolution. This paper provides an overview of the Internet use in politics and the applications available for such purpose. The paper highlights specifically Internet use in politics in Egypt. The paper\u27s objective is to investigate how Egyptians are using the Internet in politics in accordance with the relevant literature - such as, channels used and main functions -, and whether it could be a powerful mean in transferring Egypt towards democracy
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
