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
CARACTERISATION DES BONNES PRATIQUES EN ECO-CONCEPTION POUR LA FORMATION DES INGENIEURS-CONCEPTEURS : SYNTHESE DES DIMENSIONS, METHODES, ACTIVITES ET OUTILS
No full textDue to an increasing world pressure on natural resources, the evolution of professional practices of engineering designers towards more environmental friendliness becomes compulsory. Today it is necessary to provide engineering designers with a high-quality eco-design education. Our approach is to characterize eco-design best practices in order to build a bridge between the design and the eco-design of products and services. Within this perspective, a framework including six dimensions and associated levels, which characterize the core themes of the eco-design activity is proposed. Our main enquiry consists in three redesign experiments. The experimental work is conducted with various existing eco-design tools to highlight several eco-design dimensions: the eco-design process and its typical steps, the integration of stakeholders and the systemic level of the process. Thanks to the observation of novice and expert eco-designers, it is possible to formalize a set of eco-design competences. Those are displayed against the proposed framework, and validated by a national sample of persons in charge of eco-design curricula. Eco-design practices are eventually put back in the context of design to show their complementary character.Devant la pression exercée au niveau mondial sur le milieu naturel, l’évolution des pratiques professionnelles des concepteurs vers plus de respect des contraintes d’environnement est une condition impérative. Il est aujourd’hui nécessaire d’assurer aux concepteurs une formation initiale dans le domaine de l’éco-conception. Notre approche consiste à caractériser les bonnes pratiques de l’éco-conception afin de créer une passerelle entre concevoir et éco-concevoir des produits et services. Nous construisons à cet effet un référentiel d’activité multi-niveaux à 6 dimensions représentatif des thématiques à aborder. Le cœur de notre étude consiste en trois expérimentations de reconception de produits. Elles sont menées à l’aide d’outils d’éco-conception variés, permettant de mettre en lumière plusieurs dimensions caractéristiques parmi les 6: le processus d’éco-conception et ses étapes, l’intégration de parties prenantes et le niveau de remise en cause résultant du processus. Grâce à l’observation d’éco-concepteurs novices et experts, nous formalisons un ensemble de compétences déclinées sur le référentiel, que nous validons auprès d’un panel de responsables nationaux de formation à l’éco-conception. Finalement les pratiques d’éco-conception sont replacées dans le contexte de la conception pour montrer les complémentarités entre ces deux approches
Concevoir des systèmes socio-techniques et innover dans une perspective de soutenabilité: Vers une synergie entre imaginaire et rationalité
No full textL’ensemble des travaux synthétisés dans ce mémoire s’attachent à outiller l’exploration problème-solution en conception et innovation centrée usager, en éco-conception et en éco-innovation. Il s’agit de produire des supports méthodologiques à destination des concepteurs au sens large : ingénieurs-concepteurs mais aussi designers industriels. Ces concepteurs sont aujourd’hui confrontés à (1) la nécessité de concevoir des produits, mais aussi des services voire des systèmes socio-techniques mêlant solutions technologiques et scénarisation des usages et modes de vie ; (2) à l’impératif d’intégrer une dimension environnementale et sociale à la conception pour s’inscrire dans une transition soutenable. Nous sommes à l’heure actuelle dans une période d’instabilité, d’incertitudes et de bouleversements environnementaux et sociaux. Afin de saisir ces défis, je propose d’orienter mes futures activités et collaborations suivant trois axes exploratoires. Le premier axe, le plus large, s’intéresse à la modélisation de la transition des usages entre passé et futur et à la conception de futurs usages soutenables. Le second axe se concentre sur l’articulation entre une pensée rationnelle et des imaginaires créatifs en conception, en explorant par exemple le potentiel de la narration et du jeu en conception participative, et plus largement les apports de pratiques artistiques à la conception de systèmes socio-techniques en transition . Le troisième axe propose un cadre pour penser la relation de l’innovation à la technologie dans une perspective de soutenabilité, qui interroge les approches dites basses et hautes technologies
