Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Who's in charge? Negotiation, manipulation and comic licence in the work of Mark Thomas
Mark Thomas is a prolific joker and social commentator. While many comedians restrict their rebellions to verbal attacks, Thomas’ material takes direct, practical effect via pranks. Under the protection of comic licence, Thomas is permitted to engage in a range of mercilessly subversive activities, and to celebrate them onstage. Like all comedians, Thomas is bound by the limits of his licence: his live audiences will reject material that crosses the line.
However, the boundaries of that licence are malleable, and audiences are not necessarily as discerning as one might think. This article argues that manipulation and influence are necessary components of comic licence. I first examine the nature of comic licence, demonstrating that its source has serious implications for its limits and boundaries. I then analyse Mark Thomas’ performance in detail, weighing up the extent to which the audience may police the boundaries of comic licence against the possibility that the comedian may dupe them into laying down their resistance altogether
Detection of retroviral indicators in myeloproliferative diseases
Previous work both in the U.S.A and Switzerland has suggested the possibility of a retroviral aetiology for the myeloproliferative disorders, polycythaemia vera and essential thrombocythaemia. The evidence for this was equivocal and the work presented here is an investigation of these diseases, with the intention of clarifying this situation. Evidence is presented for the existence of reverse transcriptase activity being present in the platelets of patients with these disorders. Electron microscopy of sucrose gradient fractions in which this enzyme activity has been detected, displayed particles which are morphologically indistinguishable from retroviral particles prepared in the same way. Northern blot analysis failed to detect the presence of RNA with any homology to a variety of retroviral probes, though this cannot exclude the possibility that a retrovirus may be present.
