Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
Planetary boundaries: The Upper Limit of the Sufficiency Corridors
The sufficiency LabThe Planetary Boundaries framework is a scientific concept developed to define the safe operating space for human activities on Earth. Introduced by Johan Rockström and colleagues in 2009 (external link), it identifies nine critical processes that regulate the stability and resilience of the Earth system, such as climate change, biodiversity loss, and biogeochemical cycles. By staying within these boundaries, humanity can avoid triggering large-scale, abrupt, or irreversible environmental changes

Conférence de vulgarisation sur les limites planétaires et les enjeux de sa territorialisation
National audienceCette conférence consiste dans une première partie à explique la construction du cadre des limites planétaires et analyses qu’il propose pour chacun des 9 processus qui le constitue. Elle consiste dans une seconde partie à évoquer les possibilités de mobiliser ce cadre à plus petite échelle, celle d’un territoire, pour mettre en perspective l’impact de nos décisions. Cela amène notamment à introduire le cadre du donut. Des perspectives sont données en fin de conférence sur les observations réalisées au cours du travail de thèse sur la mobilisation des limites planétaires et du donut pour appuyer à la décision locale.Cette conférence a été réalisée en janvier 2024 à l’Institut Agro Dijon et en mai 2024 à Vannes (festival Climat de fête)
