The Gaia Methodology Process
No full textGaia was the first complete methodology proposed for the development of multi-agent systems (MASs), and was subsequently improved to designing and building systems in complex, open environments. Gaia focuses on the use of the organizational abstractions to drive the analysis and design of MAS. Gaia models both the macro (social) aspects and the micro (agent internals) aspects of MAS, and devotes a specific effort to model the organizational structure and the organizational rules that govern the global behavior of the agents in the organization. In this chapter we present the complete documentation of the Gaia process following the IEEE-FIPA Documentation Template
Adaptable Multi-Agent Systems: The Case of the Gaia Methodology
Full text linkChanges and adaptations are always necessary after the deployment of a multi-agent system (MAS), as well as of any other type of software systems. Some of these changes may be simply perfective and have local impact only. However, adaptive changes to meet new situations in the operational environment of the MAS may impact globally on the overall design. More specifically, those changes usually affect the organizational structure of the MAS. In this paper we analyze the issue of design change/adaptation in a MAS organization, and the specific problem of how to properly model/design a MAS so as to make it ready to adaptation. Special attention is paid to the Gaia methodology, whose suitability in dealing with adaptable MAS organizations is discussed also with the help of an illustrative application example
Experiences in e-Governance from an ICT4G Perspective: Case Studies and Lesson Learned
No full textIn a world characterized by rapid change driven by globalization, an ICT-based economy transforma- tion poses some challenges and opportunities for the private sector and the government sector alike. ICT has for some time been at the core of government tasks, inseparable from strategy, planning, con- sultation and implementation to improve citizen’s life in different ways. Nevertheless, indications are that the government sector has been falling behind in these practices (mostly in developing countries), compared to the private sector. This realization has prompted some governments to put ICT high on their policy agendas, with the aim of introducing ICT-based solutions to improve their public administration processes, and thus deliver ‘quality public services’. We define ICT for Good (ICT4G) as the use of ICT to addressing critical problems in societies characterized by low ICT penetration in a way that life is impacted for the better. Along this line, we have been working on the design, development, and evalua- tion of ICT solutions that directly require the involvement of citizen on the usage of the developed system itself and/or on the decision-making processes. In this chapter, we discuss our experiences and lessons learned in this holistic approach to e-Governance projects from the ICT4G perspective and the role it can play for developing countries
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
