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
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

No full textThis book contains a series of essays linked by a common thread: the relationship between technology, languages and informal educational practices. Connecting these three subsets is the concept of culture, understood not as a simple common denominator but as a lens for reading all the phenomena examined. This means attempting to read technology from the subjects and not from the tools they use. It is a distinction, we think, not insignificant. If, in fact, we consider digital technologies to be mere tools, whose value changes according to the use made of them, we risk falling into an obsolete determinism that cannot tell us anything about the transformations that these technologies have triggered. If, instead, we bring to light their nature of social devices we can try to grasp their constituent power. It is not a gamble to say that devices produce subjectivity: we need only think of the set of social and communicative practices that have arisen around the use of Apps, of the subcultures generated by video games, of the online communities that, thanks to connective psycho-technologies, have chosen the Net as their home. All this inevitably reverberates on learning processes, which today must be contextualized within the multiplicity of environments – real and virtual – in which they are located. The complex nature of these processes, moreover, directly influences the modes, forms and times of teaching, whose territories now expand far beyond the institutional boundaries of the school and are threatened by the proliferation of informal educational agencies and didactic strategies that are often difficult to understand but, not for this reason, less effective
