Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Hoër onderwys as navorsings- en studiegebied in Suid-Afrika: 'n Historiese en tematiese perspektief

Tydskrif vir Geesteswetenskappe, 52(3), 382-396This contribution addresses three issues concerning higher education as a field of study and research in South Africa. It starts off by tracing a number of moments in the historical development of higher education studies and research in South Africa – particularly in the period prior to the 1994 transition of political power. Next, the question of what the field of higher education studies and research entails internationally, is explored. The thematic categorisation of Malcolm Tight from the United Kingdom is used to determine international publication trends as derived from his analysis of 406 articles in 17 selective academic journals for the period 2002 – 2003. Tight identified eight major categories or clusters of publications in the field of higher education research. These were: (1) Teaching and learning in higher education; (2) Curriculum planning and design; (3) Student learning experiences; (4) Quality in higher education; (5) Systems and policies in higher education; (6) Institutional management; (7) Academics and academic work; (8) Knowledge and the nature of knowledge in higher education. For the South African position, three different analyses of studies and articles on higher education were explored. The first included an analysis by Muller (1998), who analysed 371 titles of research projects as well as master’s and doctoral titles that were registered on the Nexus database of the National Research Foundation for the period 1993 – 1997. A second analysis, by Uys and Frick (2009), comprised the abstracts of 1237 articles which were published in the South African Journal of Higher Education in the period 1987 – 2007. Although not directly comparable to Muller’s, this analysis indicated similar as well as different clusters of research undertaken. A third analysis, by Wilkinson and Van Jaarsveldt (2009), comprised 159 articles published by the South African Journal of Higher Education between 2006 and 2007 as one section of their research. The other section looked at 382 titles of master’s and doctoral theses as registered on the database of the National Research Foundation for the period 2006 – 2007. From a comparison between the international analysis by Tight on the one hand and the three South African analyses on the other, it was concluded that while the Tight mapping was largely confirmed by the South African anlyses, two further local themes have emerged and another seems to be evolving. The new themes are (9) Transformation in/of higher education and (10) Higher Education and community involvement. A theme that seems to be evolving, is research on the role and use of electronic information and communication systems in higher education, while research on quality issues in higher education seems to be on the downturn or, at least, not growing. Finally, the authors have highlighted a number of issues for possible future exploration in order to extend and promote higher education as a field of research and studies in South Africa. These include the continuing and pressing question of student access to higher education, the relationship of higher education to other levels of post-school education and the effects of the economic downturn worldwide on higher education institutions and systems. It is also suggested that a more accurate and continuous mapping of the field can assist policy makers, study leaders and postgraduate students in making more informed choices on selecting and funding research priorities and topics in the field of higher education studies and research.Publishers versio
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
