Information systems development: methodologies, techniques and tools (3rd edition)
No full textFirst published almost ten years ago, Information Systems Development is used by lecturers and students worldwide. Through long experience of teaching with the text and feedback from colleagues and students, the authors have continued to build from the solid foundations of the original text. The new 3rd edition of Information Systems Development has been updated and enhanced to reflect the latest developments in IS technology, and to meet the needs of a new generation in IS studies.The book contains comprehensive coverage of diverse topics including Oracle applications, UML notation, RUP, RAD and DSDM. There is a new section on SAP and other ERP systems. E-commerce and web applications such as Dreamweaver are examined, as well as additional information on package development and component based design. The authors further illustrate how these various technologies integrate with social and economic factors to provide a thorough examination of Information Systems Development.Due to this broad content base, Information Systems Development is suitable for a wide range of degree programs without impacting the unique requirements of either computer science, or business and management courses. Both theoretical models and real-world examples provide an engaging and practical text, and there is considerable web-based support material available for both lecturers and students.<br/
Where now for development methodologies?

Reflections on information systems practice, education and research: 10 years of the Information Systems Journal
No full textThis paper celebrates the 10-year anniversary of the Information Systems Journal (ISJ) and the Editors reflect on the papers that have been published over that period and the changes that have occurred in the discipline of information systems. In the opening paper of ISJ, we suggested that the 'launch of a new journal in information systems prompts thought and debate concerning the state of the subject area and some contemplation of its past and future'. We discussed three areas of this 'not-yet-established discipline': practice, education and research. In this follow-up paper, we forgo our convention of ISJ editors not publishing in the Journal. We examine the issues raised in the first paper and consider what has happened in the intervening years as charted in the ISJ. The overview is necessarily selective, probably Anglocentric (with, perhaps, a slight Francophile tinge), sometimes downright opinionated, as well as over-estimating, perhaps, the contribution of one particular IS journal
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
