No full textGoing 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
HMD Praxis der Wirtschaftsinformatik / Abhängigkeiten im Lebenszyklus von OGD-Applikationen – Eine Analyse der Auswirkungen von Änderungen am Beispiel einer langlebigen Webapplikation
No full textZusammenfassung Open Government Data-Initiativen ermöglichen den Zugriff auf und die Nutzung von Daten der öffentlichen Verwaltung. Diese Angebote werden oftmals als Grundlage für unterschiedliche, häufig nicht-kommerzielle Applikationen genutzt. Die Nutzung unterliegt in der Regel nicht der Regelung durch einen Vertrag, sondern durch Richtlinien. Die bereitgestellten Daten und Angebote unterliegen jedoch einer dynamischen Veränderung, da sie sich fortentwickeln oder durch neue Angebote ersetzt werden. Die Art und Weise der Kommunikation solcher Änderungen in Bezug auf Daten oder Schnittstellen seitens der Anbieter von Open Government Data (OGD) ist in vielen Fällen nicht ausführlich dokumentiert. Dies impliziert, dass OGD-Applikationen, die von diesen Daten abhängen, eine kontinuierliche Überprüfung der Änderungen, Konsistenz und Verfügbarkeit gewährleisten müssen. Dies resultiert in einer suboptimalen Nutzung von OGD, sowie in nur wenigen langfristig existierenden Applikationen. Eine Webapplikation, die als Hobbyprojekt bereits seit 2015 existiert und für eine Großstadt mit mehr als einer Million Einwohner*innen Abfahrtszeiten von öffentlichen Verkehrsmitteln je Haltestelle in Echtzeit darstellt, dient als Basis für eine Analyse von Abhängigkeiten, Änderungen und deren Auswirkungen auf diese OGD-Applikation. Die Analyse hat ergeben, dass spezifische Änderungen seitens des OGD-Anbieters zu einer Nichtverfügbarkeit der Applikation führen können. Aus den identifizierten Abhängigkeiten wurden vier Typen abgeleitet, die sich in ihren Auswirkungen auf die OGD-Applikation und deren Verfügbarkeit unterscheiden. Auf dieser Grundlage wurden Handlungsempfehlungen für OGD-Anbieter und OGD-Nutzer*innen abgeleitet.Abstract Open Government Data initiatives enable access to and use of public administration data. These offerings can be used as the basis for various, often non-commercial applications. Their use is generally governed by guidelines rather than contracts. However, the data and offerings provided are subject to changes as they evolve or are replaced by new offerings. The way in which Open Government Data (OGD) providers communicate such changes to data or interfaces is often not thoroughly documented. This implies that OGD applications that depend on these offerings must ensure continuous monitoring of changes, consistency, and availability. This results in suboptimal use of OGD and only a few long-term applications. A web application, created by “hobbyists” that has existed since 2015 and displays real-time public transport departure times for each stop in a large city with more than one million inhabitants serves as the basis for an analysis of dependencies, changes and their effects on this OGD application. The analysis revealed that specific changes made by the OGD provider can lead to the unavailability of the application. Four types of dependencies were identified, differing in their impact on the OGD application and its availability. Based on these findings, recommendations for OGD providers and OGD users were derived
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
