Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
Requirements engineering: a review of processes and techniques
Requirements engineering is the process of discovering the purpose and implicit needs of a software system that will be developed and making explicit, complete, and non ambiguous their specification. Its relevance is based in that omission or mistakes generated during this phase and corrected in later phases of a system development lifecycle, will cause cost overruns and delays to the project, as well as incomplete software. This chapter, by using a conceptual research approach, reviews the literature for developing a review of types of requirements, and the processes, activities, and techniques used. Analysis and synthesis of such findings permit to posit a generic requirements engineering process. Implications, trends, and challenges are then reported. While its execution is being mandatory in most SDLCs, it is done partially. Furthermore, the emergence of advanced services-oriented technologies suggests further research for identifying what of the present knowledge is useful and what is needed. This research is an initial effort to synthesize accumulated knowledge
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We 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
Process models of SDLCs: comparison and evolution
The software engineering discipline has developed the concept of software process to guide development teams towards a high-quality end product to be delivered on-time and within the planned budget. Con- sequently, several software-systems development life-cycles (PM-SDLCs) have been theoretically formu- lated and empirically tested over the years. In this chapter, a conceptual research methodology is used to review the state of the art on the main PM-SDLCs formulated for software-intensive systems, with the aim to answer the following research questions: (a) What are the main characteristics that describe the PM-SDLCs?, (b) What are the common and unique characteristics of such PM-SDLCs?, and (c) What are the main benefits and limitations of PM-SDLCs from a viewpoint of a conceptual analysis? This research is motivated by a gap in the literature on comprehensive studies that describe and compare the main PM- SDLCs and organizes a view of the large variety of PM-SDLCs
