Christophe Defeuilley, L’entrepreneur et le Prince. La création du service public de l’eau
No full textDerrière le titre poétique de cet ouvrage, Christophe Defeuilley nous livre une analyse historique comparée de l’établissement des services publics d’eau potable dans les trois métropoles que sont Londres, New York et Paris, villes les plus peuplées du monde à l’aube du XXe siècle. C’est par le prisme de sa discipline, l’économie, associé à une perspective de temps long (du XVIe au début du XXe) resserrée en grande partie sur les acteurs privés et publics, que l’auteur retrace l’évolution et ..
Retail Competition in electricity markets Christophe Defeuilley Larsen Retail competition in electricity markets Retail competition in electricity markets
No full textAbstract : The introduction of competition into retail electricity supply gave rise to great expectations. However, to date its performance has proven less than stellar, owing primarily to the theoretical concepts underpinning this reform, which draw heavily on the Austrian school. Neither consumers' decision processes nor this sector's technical paradigm were adequately accounted for, leading to an uncorrect estimation of the expected impact of opening to competition. Short-and medium-term prospects for the evolution of retail markets must be reconsidered from the perspective of greater stability : not a generalization of competition, but rather a persistent segmentation between active and inactive clients ; not a large and rapid diffusion of radical innovations in commercialisation, with the potential for undermining the incumbents' positions
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
