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
Ebook proceedings of the ESERA 2013 conference : science education research for evidence-based teaching and coherence in learning
No full textThe goal of this electronic book is to publish improved versions of the proposals presented (after peer evaluation) at the ESERA 2013 conference. These updated versions of the papers take into account the discussion which took place during the presentation as well as the feedback received from the reviewers. A total of 960 submissions were received for the conference out of which 339 papers are included in the e-book, following the two rounds of review. On the whole, the e-book presents a comprehensive overview of ongoing studies in Science Education Research in Europe. It represents the current interests and areas under emphasis in the ESERA community at the end of 2013. The e-book contains sixteen parts corresponding to the 16 strands of the ESERA 2013 conference. Each part is co-edited by two or three persons, most of whom were strand chairs. The three formats of presentation made during the conference are published in this e-book. The length for a single oral presentation or poster is between 6 and 12 pages. For the symposium there are two possibilities: The whole symposium can be presented as a single paper of 6-12 pages or each contribution can be considered as a single oral presentation (6-12 pages). All papers in this e-book correspond to communications submitted and accepted for the ESERA 2013 conference that were reviewed by two or three referees, prior to presentation in September 2013. Moreover the co- editors carried out a global reviewing of the updated versions of the papers, which were all submitted after the conference. ESERA or the editors and co-editors do not necessarily endorse or share the ideas and views presented in or implied by the articles included in this book

Science Learning and Citizenship. Part 5 : nature of science, history, philosophy, sociology of science
No full textVariations 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
