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
Role of processes in electronic government (case of Egypt)
No full textThis paper highlights the importance of processes in any egovernment program by introducing the main areas of change in them. It investigates focal e-government processes through conducting a research on four organizations presenting Egyptian public organizations. Results revealed that determination of motives of business processes\u27 change and documenting such changes proved to be the most important factors in in the processes to be carried out in an e-government project. Findings highlighted also a lack of internal integration of business processes in three of the four organizations studied due to the absence of Intranet or to the unwillingness to use an existing one. Also, business process integration among governmental organizations is still in an early stage and requires further improvements. Finally, processes undertaken in evaluating citizens\u27 usage of each agency\u27s website are highly considered and analyzed
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
Use of Information Systems and Electronic Commerce success models to assess Electronic Government projects
No full textElectronic Government (E-Government) is presently recognized as a key enabler of citizen-centric, cooperative, and seamless modern governance. E-government implementation implies a profound transformation in the way government interacts with the governed, and also a reinvention of its internal processes. Many countries worldwide allocate large investments for egovernment projects, which necessitates evaluating them to ensure their viability in realizing their goals. Since e-government is mainly an application of both Information Systems (IS) and Electronic Commerce (E-Commerce), it becomes essential to investigate assessment models in both areas to choose a suitable model capable of assessing e-government projects. This paper reviews IS and e-commerce success models, and verifies their applicability in assessing E-Government Readiness (EGR) on an organizational scale. EGR assessment should consider all factors affecting e-government success comprising IS strategy, technology, human resources, and business processes. Analysis of IS and e-commerce success models in addition to e-government and e-readiness evaluation approaches lead to the development of an EGR framework encompassing all these pivotal factors. Conclusion drawn from this study provides a systematic approach to assess EGR based on strong theoretical foundation in IS and ecommerce fields, both well-established and fairly tested fields compared to a relatively recent field as e-government
