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
How Are We Doing on Brexit?
Get PDFUnderstandably we have heard little recently from Remainers or the second referendum brigade. As the football fans chant “they’ve all gone quiet over there”. Right from 10pm on election night when an accurate forecast announced Boris Johnson’s stunning victory the opponents of Brexit have been too shocked to say much
Has Brexit Been Stopped?
Get PDFBritish politics oscillates between two modes on Brexit and changes at the flick of a switch. Coinciding with elections it is obvious that there exists a large and determined vote to leave the EU which probably forms a majority. This was true of the Brexit referendum, the 2017 General Election and the 2019 European Elections
The NI Protocol. Fraying at the Edges or Beginning to Collapse?
Get PDFThe signs are not good for the EU on the Northern Ireland Protocol. Collapse is in the air but of course the EU wants to maintain an evolving fiction that the UK’s legal obligations will be fully realized once a few tweaks are negotiated to make trade flow more easily across the Irish Sea border. Meanwhile, the UK has been on a ‘go slow’ in implementing the Protocol ever since it came into force at the start of 2021. A unilateral grace period was imposed by Lord Frost to suspend EU checks of food products and a ban on imports of chilled meat. The EU took legal action but with not much to gain in practice little has subsequently been heard of the legal case. Further grace periods were agreed by the EU in mid-2021 to avoid the threat of further unilateral action
