    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

    The satisficing price set by real estate agents

    L'agent immobilier, en tant qu'intermédiaire, facilite la mise en relation entre vendeurs et acquéreurs de biens immobiliers. Dans le cadre d’une prestation de services, le praticien accompagne la fixation du prix de vente. Pour ce faire, il considère les attributs du logement, les conditions du marché, le profil du vendeur, la concurrence avec les autres intermédiaires, les outils technologiques à sa disposition et s’appuie sur son expérience personnelle.Face à la complexité de ces multiples considérations, comment les agents immobiliers procèdent-ils pour établir le prix d’un logement ? Si le prix hédonique d’un logement se fixe à partir de ses caractéristiques et des conditions du marché, comment, dans les faits, les intermédiaires immobiliers arbitrent-ils entre l’application de ce principe théorique, d’une part, et la prise en compte de leurs propres intérêts et limites, d’autre part ? Finalement, quel est l’impact des intermédiaires sur les prix du marché immobilier ?Cette recherche montre qu’au-delà de l’analyse de l’interaction entre l’offre et la demande, le professionnel recourt à un ensemble de règles implicites, établies individuellement ou collectivement, afin de formuler un prix « satisfaisant » (H. Simon) pour l’ensemble des acteurs impliqués dans la transaction, y compris lui-même.Tout d’abord, le prix estimatif est calculé à partir d’une information imparfaite et de décisions subjectives ou conventionnelles. Ensuite, motivée par l’intensité de la concurrence entre intermédiaires, une pression à la hausse exercée sur le prix affiché se répercute dans le prix final. Pour aboutir à ce dernier, l’agent immobilier, en réponse à ses impératifs de rentabilité, incite fortement les vendeurs à revoir leurs attentes à la baisse.Par conséquent, l’étude de l’impact de l’agent immobilier sur le prix d’un logement montre que le marché ne corrige pas la subjectivité des acteurs, mais s’en alimente. Dans la lignée des travaux de Keynes et de Shiller, relatifs aux dimensions psychologique et sociale des marchés, ce sont les acteurs qui construisent les prix sur le marché immobilier plutôt que les prix qui coordonnent les acteurs en s’imposant à eux.Cette recherche se concentre sur le marché résidentiel formé par 33 communes du Val-d’Oise. Selon une méthode mixte, elle exploite des entretiens semi-directifs (n=16), les données internes d’une agence immobilière (n=585 mandats), une revue de la presse spécialisée (n=578 articles) et de la communication institutionnelle (n=63 communiqués de presse d’organisations professionnelles) ainsi qu’une base de prix agrégés (n=1970 transactions) pour étudier les pratiques professionnelles des agents immobiliers. Le cadre théorique convoqué combine l’économie comportementale et l’économie des conventions pour comprendre le processus de décision, tant à travers les choix individuels que les interactions sectorielles.Ce travail aboutit à la formulation de recommandations destinées aux acteurs publics chargés d’améliorer le fonctionnement du marché immobilier.The real estate agent, acting as an intermediary, facilitates the matching of sellers with buyers in real estate transactions. As part of a comprehensive service, the professional assists in setting prices. To achieve this, they consider the property's attributes, market conditions, the seller’s profile, competition with other intermediaries, the technological tools at their disposal, and their personal experience.Given the complexity of these multiple considerations, how do real estate agents determine the price of a property? If the hedonic price of a property is determined by its characteristics and market conditions, how do real estate intermediaries, in practice, balance the application of this theoretical principle on the one hand, and the consideration of their own interests and limitations on the other? Ultimately, what is the impact of intermediaries on real estate market prices?This research shows that, beyond analysing the interaction between supply and demand, professionals rely on implicit rules, established either individually or collectively, to formulate a 'satisficing' price (H. Simon) for all parties involved in the transaction, including themselves.First, the estimated price is calculated based on imperfect information and subjective or conventional decisions. Then, driven by the intensity of competition among intermediaries, upward pressure on the listed price influences the final price. To reach this final price, the real estate agent, responding to their profitability imperatives, strongly encourages sellers to lower their expectations.Consequently, the study of the impact of real estate agents on property pricing shows that the market does not correct the subjectivity of actors but rather feeds on it. Following the analyses of Keynes and Shiller, which relate to the psychological and social dimensions of markets, it is the actors who construct prices in the real estate market rather than prices coordinating the actors by imposing themselves upon them.This research focuses on the residential market comprising 33 municipalities in the Val-d'Oise. Using a mixed-methods approach, it employs semi-structured interviews (n=16), internal data from a real estate agency (n=585 listing contracts), a review of specialised press (n=578 articles), and institutional communications (n=63 press releases from professional organisations), as well as an aggregated price database (n=1 970 transactions) to study the professional practices of real estate agents. The theoretical framework combines behavioral economics and convention theory to understand the decision-making process, both through individual choices and sectoral interactions.This work concludes with the formulation of recommendations aimed at public authorities responsible for improving the functioning of the real estate market

    Dispelling the Myths Behind First-author Citation Counts

    We 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

    We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
