The changing geography of the European automobile system
Full text linkBased on the research done by the European thematic network CoCKEAS (FP6), the paper analyses the recent changes in the European automobile geography. It discusses the impacts of the EU enlargement: integration of Central and Eastern European countries and new spatial competition for Southern European countries (Spain, Portugal). The study of the geographic distribution of automobile production within Europe focuses on the dynamic of specialisation of regions through collective learning processes, and the clustering of design and assembly activities (supplier parks).automobile industry, cluster, Europe, location, proximity, spatial division of labour

Un ré-examen de la relation entre variété et échelle de production à partir de l'industrie automobile
No full textA re-examination, based on the automobile industry, of the relationship between variety and scale
of production by Bruno Jetin and Yannick Lung
Based on specific statistical time-series of product variety and production volume of passenger cars for the main car makers during the period 1950-73 (Europe, USA, Japan), the paper discusses the relationships between and scale of production. It demonstrates that there is no incompatibility between the search for scale economies - associated with mass production - and growth in variety of supply. These results are deduced from an econometric analysis (panel data). A dynamic model of the relation between scale and variety - based on a learning process - is then proposed.Un réexamen de la relation entre variété et échelle de production à partir de l'industrie
automobile par Bruno Jetin et Yannick Lung
Prenant appui sur la reconstitution de séries statistiques longues relatives à la variété de la gamme et au volume de production des principaux constructeurs automobiles mondiaux sur la période 1950-93 (Europe, USA, Japon), l'article discute les relations entre variété de l'offre et échelle de production. Il met en évidence qu'il n'existe pas d'incompatibilité entre la recherche d'économies d'échelle, caractéristique de la production de masse, et l'accroissement de la variété de l'offre. Ces résultats sont obtenus à partir du traitement économétrique par la méthode des données de panel. L'article propose ensuite un modèle dynamique de la relation entre échelle et variété dans un schéma explicatif centré sur les processus d'apprentissage.Jetin Bruno, Lung Yannick.

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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
