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
Do blended virtual learning communities enhance teachers’ professional development more than purely virtual ones? A large scale empirical comparison
No full textThis article examines whether a mixture of virtual and real-life interaction—in contrast to purely virtual interaction—among some members of online communities for teachers is beneficial for all teachers' professional development in the whole community. Earlier research indicated that blended communities tend to face fewer trust and free rider problems. This study continues this stream of research by examining whether blended communities provide more practical benefits to teachers, both in terms of perceived improvements to their teaching capabilities as well as for their substantial understanding of their core topic. In addition, it is tested whether blended communities provide more information about vacancies, as teachers' mobility is regarded as too low in the EU. The analysis uses survey data from 26 online communities for secondary education teachers in The Netherlands. The communities are part of a virtual organization that hosts communities for teachers' professional development. The findings indeed show beneficial effects of blended communities. Moreover, the results modify earlier claims about the integration of online communication with offline interaction by showing that complete integration is unnecessary. This facilitates a scaling up of the use of online communities for teachers' professional development
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
Reducing problems of sociability in online communities : integrating online communication with offline interaction
No full textSocial network researchers have claimed that relations offline affect relations online; however, it is unclear which characteristics of online interaction are affected by the existence of offline relations. This article examines whether a mixture of virtual and real-life interaction—in contrast to purely virtual interaction—among some members of knowledge-sharing online communities reduces the prevalence of problems that the whole community faces. Typical problems of sociability that increase risk of failure in knowledge sharing include a lack of trust between members, free rider behavior, and a lack of stable membership. This analysis uses survey data from 26 online communities that are part of a virtual organization that hosts communities for teachers. The findings provide evidence for the existence of more trust and less free riding in mixed communities but not for greater membership stability. Results contribute to knowledge of how offline networks influence online relations; namely, offline networks reduce problems of sociability, thereby facilitating online knowledge sharing. Moreover, the results modify earlier claims about the integration of online communication with offline interaction by showing that complete integration is unnecessary
