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
Margaret Thatcher, 1975–9
No full textMargaret Thatcher entered the record books as the first female leader of the Conservative Party and as the longest continuously serving Prime Minister in modern British history. She was leader of the party for fifteen years (1975–90) and Prime Minister for eleven-and-a-half (1979–90). We are here concerned with the four years she spent as Leader of the Opposition
James Callaghan, 1979-80
No full textThis chapter attempts to review and reasess Callaghan's turbulent stewardship of the Labour Party in the period immediately following election defeat in 1979 as Leader of the Opposition. It evaluates his leadership on dimensions of public communication; effectiveness in constructing public policy platforms; party management and emotional intelligence in coping with the demands of the role, but argues, in Callaghan's case, that intra-party and broader political developments and context were mightily important and, despite his wide experience and obvious skills, party trends and priorities were passing him by, at least temporarily. As such, his brief post-election leadership of the party exposed him as not so much a ‘caretaker’ or ‘night watchman’ as ‘lame duck’ Leader of the Opposition
Neil Kinnock
No full textPolitical journalists often refer to Leader of the Opposition as the hardest job in politics, and yet despite this opposition studies has been largely neglected by political academics. To address this gap, this edited book brings together a team of leading British Politics experts to evaluate the performance of each Leader of the Opposition in the post-war era. Each Leader of the Opposition from Churchill to Cameron is assessed in terms of their proficiency as public communicators; their effectiveness in constructing viable public policy platforms; their abilities in party management and their emotional intelligence or how they coped with the demands of the role. Through these evaluations conclusions are drawn on how Leaders of the Opposition are increasingly less experienced when acquiring the position and how in the era of valence politics expectations of them as Leader are higher and tolerance of failure is lower
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
