Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Customer order fulfilment in mass customisation context - an agent-based approach
No full textInternational audienceThe ever increasing customer specific needs require suitable strategies to accommodate his requirements and deliver exactly what he wants and in due course. Mass customisation, as a successor of mass production is one of these strategies, it aims at satisfying customer needs with near mass production efficiency. However, achieving efficiency is challenged by several issues such as customer order fulfilment in a customisation environment. In fact, product variety induced by customer choices requires flexible production systems able to manage internal complexity caused by such external variety. This paper proposes a multi-agent-based model to manage customer orders by: 1) defining production requirements of each order; 2) simulating the execution of the production and delivery operations. It then illustrates the proposed model with a case study and investigates the impact of inventory management on the enterprise economic performance. The case study shows how the model supports the decision-making process with respect to customer order fulfilment

Évaluation de la performance d’entreprises dans le contexte de la personnalisation de masse durable
No full textDemand variety and emergence of niche markets, accompanied by engagement of governments and society in sustainable development makes sustainable mass customization a promising strategy. According to which, companies should meet the needs of individuals on a large scale, while ensuring sustainable development. This requires a continuous process of performance evaluation of the company to make sure it moves forward to sustainable mass customization.In this thesis, we focused on sustainable mass customizing enterprises’ performance evaluation, more particularly we addressed the question: how can we help sustainable mass customizing enterprises measuring and improving their performance?We have proposed a conceptual model of the sustainable mass customizing enterprise (SMC-E) where we grouped enterprise objects impacting enterprise performance. Such a model provided the basis for building a simulation model aimed at evaluating different improvement scenarios of the performance by using indicators. Improvement scenarios are identified with the help of an influence diagram which tracks the causal links between performance inductors and indicators. These latter are chosen and prioritized using a three steps method based on interviews. We have proposed a general methodology to put together coherently all the proposed tools and methods and developed a demonstrator as a first implementation effort.The proposition is illustrated with a case study in the kitchen furniture sector that showed its usefulness and pointed out several improvement rooms.La diversité de la demande et l’émergence de niches de marchés, accompagnées par la mobilisation des gouvernements et de la société en vue d’un développement durable font de la personnalisation de masse durable une stratégie prometteuse. Selon quoi, les entreprises sont amenées à répondre aux besoins des individus à grande échelle, tout en assurant un développement durable. Cela requiert une évaluation continue de la performance de l’entreprise afin de s’assurer du progrès vers la personnalisation de masse durable.Ce travail s’intéresse à l’évaluation de la performance des entreprises adoptant une stratégie de personnalisation de masse et engagées sur la voie du développement durable en tentant de répondre à la question : Comment aider les entreprises faisant de la personnalisation de masse et visant à assurer un développement durable à mesurer et améliorer leurs performances ?Afin de traiter cette problématique, nous avons proposé un modèle conceptuel qui groupe les objets d’entreprise influant sur la performance en termes de durabilité et de personnalisation de masse. Un tel modèle a également servi pour la construction d’un modèle de simulation ayant pour objectif d’évaluer différents scénarios d’amélioration avec des indicateurs de performance. L’identification de ces scénarios est supportée par un diagramme d’influence qui retrace les liens de causalité entre les indicateurs et les inducteurs de performance. Le choix des indicateurs et leur priorisation sont assurés par une méthode de trois étapes basée sur des interviews. Nous avons proposé une méthodologie générale qui met l’ensemble de ces outils et méthodes en cohérence. Nous avons également développé un démonstrateur qui présente un premier travail d’implémentation des différentes étapes de la méthodologie.L’application à un cas d’étude dans le secteur de cuisines personnalisées a montré l’intérêt de la proposition, mais a aussi permis d’identifier les zones d’amélioration
