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
Race policy and politics: two case studies from Britain
No full textThis article considers academic engagements with policy and politics and, inparticular, race and racism through two case studies. Contextualising such engagements within wide ranging debates about the relationship between academics, research, and policy and politics, two dimensions are utilised to analyse the examples presented. These are, firstly, the inside/outside (the location and extent of academic engagement) and, secondly, the link between knowledge and politics. These are applied to two examples or cases from the UK, both of which concern racism and the police. The first was a public inquiry in which the idea of institutional racism was powerfully resurrected; the second was an employment tribunal alleging racial discrimination � so the same idea may have been expected to be raised but was not. In part the abstract is concerned with this striking difference between the cases. In the two cases the author has been equivalent to an ‘observer’ and a ‘participant’, and the article sets out some dilemmas for academics when acting in public roles or arenas. The main argument is that in spite of the tenuousness of the dichotomies between theory/practice and observation/participation, as well as the ones between insider/outsider roles and instrumental and critical knowledge, they can all be significant in terms of how politics plays out and policy is fashioned
Book review: the end of policing by Alex S. Vitale
Full text linkIn The End of Policing, Alex S. Vitale offers an indictment of contemporary policing in the US, condemning not only the roles and actions of the US police, but also the extensive, growing reach of crime control and criminalisation processes. While the book cannot fully realise its ambition to envisage ‘policing without the police’, this is a welcome challenge to reformist thinking and a powerful argument against social and economic injustice, inequality and racism, finds Karim Murji
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
