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
A Basic Set of Mental Models for Understanding and Dealing with the CyberSecurity Challenges of Today
No full textFor most people, cybersecurity is a difficult notion to grasp. Traditionally, cybersecurity has been considered a technical challenge, and still many specialists understand it as information security, with the notions of confidentiality, integrity, and availability as its foundation. Although many have searched for different and broader perspectives, the complexity and ambiguity of the notion still thwarts a common understanding. While the author was developing and executing a MSc cybersecurity program for professionals with a wide variety of backgrounds and widely differing views on cybersecurity, the lack of a common understanding of cybersecurity was clearly evident. Based on these observations, the author began seeking and defining a new, transdisciplinary conceptualization of cybersecurity that can be widely agreed upon. It resulted in the publication of three scientific papers. This paper is an amalgam of the contents of the three supplemented with some extensions. It turned out that the previously introduced description of two key notions, cyberspace and cybersecurity, is still an adequate starting point. Described here is a set of additional mental models elaborating on these key notions and providing more detail on their meanings. The research suggests that this set of mental models strongly supports the description and analysis of current cybersecurity challenges and helps people understand how everyone, in his or her various roles, can contribute to reducing the related cyber risks. These claims are supported by presenting the modeling and analysis approaches of various MSc-thesis research projects executed by students when working on practical cybersecurity problems both within and outside their organisations. The author further discovered that, for a limited set of cybersecurity challenges, it was not yet possible to identify adequate mental models; this defines the agenda for future research.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Information and Communication TechnologyCyber Securit
Introduction to Rigorous Numerics in Dynamics:General functional analytic setup and an example that forces chaos
Get PDFIn this paper some basic concepts of rigorous computing in a dynamical systems context are outlined. We often simulate dynamics on a computer, or calculate a numerical solution to a partial differential equation. This gives very detailed, stimulating information. However, mathematical insight and impact would be much improved if we can be sure that what we see on the screen genuinely represents a solution of the problem. In particular, rigorous validation of the computations allows such objects to be used as ingredients of theorems. The past few decades have seen enormous advances in the development of computer-assisted proofs in dynamics. One approach is based on a functional analytic setup. The goal of this paper is to introduce the ideas underlying this rigorous computational method. As the central example we use the problem of finding a particular periodic orbit in a nonlinear ordinary differential equation that describes pattern formation in fluid dynamics. This simple setting keeps technicalities to a minimum. Nevertheless, the rigorous computation of this single periodic orbit implies chaotic behavior via topological arguments (in a sense very similar to “period 3 implies chaos” for interval maps)
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
