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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe 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
Economie fondée sur la connaissance, nouvelles formes organisationnelles et la question des frontières de la firme : une compréhension théorique historicisée de l'entreprise-réseau
No full textDans cet article, on cherche à proposer une compréhension théorique conséquente d'une des nouvelles formes organisationnelles apparues au cours des trois dernières décennies : l'entreprise-réseau. Un tel objectif nécessite selon nous de répondre à deux impératifs : 1) rendre compte théoriquement d'une caractéristique rarement mentionnée mais qui nous apparaît essentielle afin de cerner ce qui fonde véritablement la spécificité de l'entreprise-réseau : l'interpénétration des organisations à propos de la conception du produit et des composants ; 2) articuler une analyse du fonctionnement de cette forme organisationnelle particulière (le comment ?) à une analyse qui intègre les raisons de son émergence (le pourquoi ?). Disposant ainsi d'une compréhension "historicisée" de l'entreprise-réseau, on montre que cette dernière est une réponse organisationnelle au double tournant - cognitif et interprétatif - engendré par l'émergence d'une Economie Fondée sur la connaissance dans la coordination des activités au sein de la sphère industrielle
L'"espace de coordination" : une nouvelle modalité d'intégration des activités au sein de l'entreprise-réseau : théorie et illustration des pratiques de co-conception au sein des configurations modernes"
No full text12 p.Dans ce texte, on cherche à mieux cerner théoriquement la nouvelle forme de relation client/fournisseur qui se noue au sein du réseau vertical d'entreprises. Devant les difficultés rencontrées par les théories modernes d'économie industrielle afin de rendre compte théoriquement d'un fait stylisé rarement mentionné afin de caractériser cette configuration productive (l'interpénétration des organisations à propos de la conception de produit et composants), on procède à un renouvellement des catégories d'analyse couramment utilisées en nous inspirant d'un travail récent de B. Billaudot (2002). La notion d'"activité" est ainsi préférée à celle de firme comme unité d'analyse fondamentale. Approfondissant ce travail afin de mieux cerner l'interaction socio-technique qui a lieu au sein d'un dispositif caractéristique de certaines entreprises-réseau (le plateau de conception), on développe l'idée que les pratiques repérées au sein de ce dernier témoignent au final de l'existence d'une nouvelle modalité d'intégration des acteurs : l'"espace de coordination". On illustre ces développements théoriques en documentant empiriquement les différents processus qui structurent un tel espace
Pourquoi et comment faut-il sauver la sécurité hydrique ? Changement climatique, écologie politique et services écosystémiques
Full text linkMobilizing a political ecology approach, this article calls for replacing the conventional concept of water security by the hydro-social security’ones to meet the main contemporary water issues. It aims at working for a democratization of hydro-social cycle to strengthen the building of territorialized sustainable development trajectories. From this perspective, the policy implementation of the management of scientific and societal uncertainties of ecosystem services is an essential methodological prerequisite to achieve, through a negotiation process based on democratic monetary valuation, an institutionalized and "securising" compromise between stakeholders.Mobilisant une approche d’écologie politique, la démarche exposée dans cet article invite à substituer à la notion conventionnelle de sécurité hydrique celle de sécurité hydro-sociale afin de répondre aux principaux enjeux hydriques contemporains, au premier rang desquels figure l’adaptation au changement climatique. Il s’agit alors non plus de procéder à une sociétalisation marchandisée des risques hydriques mais bien d’oeuvrer à une démocratisation des cycles hydro-sociaux afin de consolider le processus de co-construction territorialisée de trajectoires de développement soutenables. Dans une telle perspective, la mise en politique de la gestion des incertitudes scientifiques et sociétales inhérentes aux services écosystémiques représente un pré-requis méthodologique incontournable devant permettre d’aboutir, via un processus de négociation fondé sur l’évaluation monétaire démocratique, à l’élaboration de compromis institutionnalisés "sécurisants"
