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
Will Internet Ever Be Secure ?
No full textThe users of the Internet in general have not developed a perception of where what security is crucial and beneficial for their applications. At present the average user is provided very few information independent of what is transported over the service and how this is done. What is needed for a secure Internet, is that security is answered on a system level or on an application level and that an appropriate level of security is reached and still is accepted by the user? These questions are primarily questions on a technical level but have a great dimension of awareness which has to be kept in mind. However, the main question is not how to secure the Internet in place but how to develop mechanisms and tools for the Internet that can seamlessly improve an ever changing media which opens up new dimensions of security risks with every new protocol system and application. Security will remain a race where comfort is often seen as a competitor
Protecting Devices by Active Coating
No full textThe presented paper demonstrates a method to embed a unique signature into a coating material used in a smart card or in the covering material of some other secure hardware device. The method bases on the impossibility of exactly reproducing a specific piece of plastic or other material used to cover the secure hardware. By using a very inhomogeneous materials or mixtures of conductors and insulators such a cover is made unique by the method of production. This inhomogeneous piece and the non-reproducible and random properties are incorporated into an electronic signature which is checked whenever needed. Assuming that the surface is covered totally with an "active coating material" it is impossible to partially penetrate or destroy the coating without destroying the signature. Unpenetrable hardware is an inevitable element in nearly all secure designs and with the promotion of digital signatures such unpenetrable hardware becomes even more important. The result gained with the presented work is the possibility to make a hardware unique depending on randomness, and to assure that penetration is not only detected but also features logical destruction of the secure hardware [PAT96]. Implementing such penetration sensors with memory enhances the security to a large extent, and since the destruction upon perceived penetration is logical there is no possible false alarm
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
