ELF and sign-making practices on YouTube: between globalization and specificities
No full textAs is well-known, the leading video-sharing website YouTube gives easy access to cross-boundary communication. Furthermore, the recently introduced ‘video-response’ option enables videobloggers to interact through videos addressing one another, thus building communication threads made of videos. Understandably, English is the privileged language in these international video threads; yet language is only part of a wide and diversified range of resources employed in video-interaction,
since gestures, facial expressions, sound and music, animations,
drawings, photos, and filmed images can all be deployed in videos. Stemming from the idea that international communication is enabled by shared semiotic practices which include, but are not limited to, the use of a lingua franca based on English (Jenkins, 2000, 2003; Seidlhofer, 2001), the present chapter carries out a multimodal analysis (Kress / van Leeuwen, 2006) on one of the largest video threads currently on YouTube. By endorsing a social semiotic perspective (Hodge / Kress, 1988), the analysis investigates:
1. how cultural specificities and differences are communicated worldwide by means of shared resources – language included –
and,
2. how signs – spread ‘globally’ from prestigious centres – are developed specifically in a given semiotic space.
Within this broad aim, the analysis also discusses the specific variety of international English which is ingrained in the linguistic practices of the thread, how these practices develop according to the participants’ needs, and the extent to which language favours (or hinders) international participation in video-interaction. Ultimately, the analysis shows that ELF can be considered as a
part of a wider shared repertoire enabling international communication. It also testifies to the fact that language contact and language creativity are part of the broader phenomenon of semiotic contact and creativity, through which both locally- and globally-originated signs are adopted, transformed, and shared by the international participants in a specific space

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
Mechanical behaviour of three organic fertilisers to optimise spreading methods in the vineyard
No full textOrganic viticulture is attracting increasing interest worldwide. Fertilisation can be carried out with different products, such as manure, the solid fraction of digestate and compost. In order to optimise the distribution rate, it is very important to previously check the physical characteristics of these materials, which are typically subjected to progressive compression during the spreading procedure. In this context, the use of dedicated sensors and specialised software devoted to piloting the rotors and bulkhead speed of the spreader is highly recommended, taking into account also the different rheological characteristics of the different matrices. A series of laboratory tests to determine the load-deformation curve were arranged. The results showed that digestate and manure behaved in a similar way, but the former was more compact with the same load
