Selling air : sociology of the "voluntary" carbon offset market
No full textCette thèse porte sur le marché dit « volontaire » des services de compensation carbone. Sur ce marché, des entreprises, qui n’ont aucune obligation de souscrire à ces services, achètent à des opérateurs privés, ONG ou entreprises, des « crédits carbone » pour « compenser » leurs émissions de gaz à effet de serre (GES). Pour obtenir ces crédits carbone, les opérateurs du marché mettent en œuvre des projets de réduction des émissions de GES dans les pays du Sud. Ces nouveaux échanges marchands du début des années 2000 ne sont pas sans susciter de critiques. Journalistes, ONG environnementales et scientifiques considèrent que ce marché, d’une part, ne permet pas de réduire efficacement les émissions de GES et, d’autre part, que les populations du Sud encourent de potentiels dangers avec la mise en œuvre de tels projets. La thèse interroge ainsi l’apparent paradoxe du choix des entreprises d’investir dans des services environnementaux contestés alors que ces derniers ne constituent pas une obligation réglementaire et peuvent mettre en danger leur réputation. En considérant le marché « volontaire » comme un « marché contesté », selon le sens donné à cette notion par Steiner et Trespeuch (2014), la thèse rend compte des conditions d’existence et de maintien de ce marché. A partir d’entretiens, d’observations et de l’analyse de sources écrites, elle examine le rôle de divers dispositifs, du travail marchand ainsi que de l’appropriation de l’offre par les acheteurs dans l’organisation de ce marché. La thèse interroge plus généralement le rapport entre économie et environnement et s’intéresse aux ressorts de l’engagement « volontaire » des entreprises pour le climat.This dissertation deals with the so-called “voluntary” carbon offset market. In this market, companies, which have no obligation to subscribe to these services, purchase “carbon credits” to “offset” their greenhouse gas (GHG) emissions from private operators (NGOs or businesses). To obtain carbon credits, operators implement GHG emission reduction projects in Southern countries. These new trade exchanges, which date from the early 2000s, provoke critics. Journalists, environmental NGOs and scientists believe that this market on the one hand does not effectively reduce GHG emissions to fight against climate change, and on the other hand that people in the South face potential dangers linked to the implementation of carbon offsetting projects. The dissertation thus questions the apparent paradox of the choice of companies to invest in contested environmental services when they are not a regulatory obligation and may endanger their reputation. By considering the “voluntary” market as a “contested market”, according to the meaning given to this notion by Steiner and Trespeuch (2014), the dissertation explores the conditions of existence and maintenance of this market. Through interviews, observations and written sources, our research analyzes the role of various market devices, but also commercial work as well as the appropriation of the offer by buyers in organizing this market. In doing so, it questions more generally the relationship between economy and the environment and is interested in the determinant factors of the “voluntary” commitment of companies for the fight against global warming
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
Relational Work as a Market Device: An Analysis of the Contested “Voluntary” Carbon Offset Market
No full textThe chapter studies the functioning of the so-called “voluntary” carbon offset market, a market in which moral controversies take place. The analysis dwells on the theoretical framework that enables us to study the functioning of a contested market through particular devices. The chapter seeks to contribute to the literature on moral struggles within markets by focusing the attention on one specific device: relational work, including several dimensions like meeting between seller and buyer, establishing contracts and maintaining the relationship with clients in the long run. By studying relational work, the authors highlight how this basic market activity is a crucial device that makes it possible for a contested market to continue to exist
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
