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
Réflexion sur le concept de liberté : ce que l’autobiographie d’un handicap évolutif nous en dit
No full textInternational audience« Réflexion sur le concept de liberté : ce que l'autobiographie d'un handicap évolutif nous en dit » De Anne-Lyse CHABERT Anne-Lyse CHABERT est chargée de recherche en philosophie au laboratoire SPHERE de Paris-Diderot depuis novembre 2018. Elle a publié Transformer le handicap chez Eres en 2017. Quand bien même elle évoque son propre handicap évolutif, loin de la simple anecdote, sa visée est toujours conceptuelle et pleinement philosophique. Article référencé comme suit : Chabert, A.-L. (2019) « Réflexion sur le concept de liberté : ce que l'autobiographie d'un handicap évolutif nous en dit » in Ethique. La vie en question, fév. 2019. « Par-delà ce village, d'autres villages, par-delà cette abbaye, d'autres abbayes, par-delà cette forteresse, d'autres forteresses. Et dans chacun de ces châteaux d'idées, de ces masures d'opinions superposés aux masures de bois et aux châteaux de pierre, la vie emmure les fous et ouvre un pertuis (1) aux sages. […] Qui serait assez insensé pour mourir sans avoir fait au moins le tour de sa prison ? Vous le voyez, Frère Henri, je suis un pèlerin. La route est longue, mais je suis jeune. » (L'OEuvre au Noir, selon les propos de Zénon, p. 18, M. Yourcenar, Folio) Comment témoigner de mon expérience de la réclusion ? Suis-je en prison ? Le handicap moteur que génère ma pathologie neurodégénérative porte-t-il en lui-même un enfermement si évident qu'il soit naturel de me demander de témoigner à propos du thème de la réclusion ? Ne sommes-nous pas tous plus ou moins en captivité, plus ou moins reclus dans nos prisons intérieures sans même qu'il soit question de handicap ? Voici donc l'enjeu qui m'a préoccupée ces derniers temps. Même si nos prisons ont sans doute changé d'allure depuis déjà plusieurs décennies, il ne me semble pas être davantage en prison a priori, pas davantage recluse que ne le serait n'importe lequel d'entre nous. Ma maladie évolutive et le handicap sévère qu'elle génère aujourd'hui, s'ils m'imposent bien des contraintes toujours plus grandes au fil du temps, toujours nouvelles, s'ils constituent toujours de nouvelles frontières qui me demandent de reconfigurer à chaque fois mon espace de vie, n'ont jamais provoqué en moi une impression d'enfermement. Dans ces espaces limités, j'a
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
Corrigendum to "Switching of a paleo-ice stream in northwest Svalbard" [Quat. Sci. Rev. 30 (2011), 1710-1725]
No full textIce streams are the fast-flowing zones of ice sheets that can discharge a large flux of ice. The glaciated western Svalbard margin consists of several cross-shelf troughs which are the former ice stream drainage pathways during the Pliocene–Pleistocene glaciations. From an integrated analysis of high-resolution multibeam swath-bathymetric data and several high-resolution two-dimensional reflection seismic profiles across the western and northwestern Svalbard margin we infer the ice stream flow directions and the deposition centres of glacial debris that the ice streams deposited on the outer margin. Our results show that the northwestern margin of Svalbard experienced a switching of a major ice stream. Based on correlation with the regional seismic stratigraphy as well as the results from ODP 911 on Yermak Plateau and ODP 986 farther south on the western margin of Spitsbergen, off Van Mijenfjord, we find that first a northwestward flowing ice stream developed during initial northern hemispheric cooling (starting not, vert, similar2.8–2.6 Ma). A switch in ice stream flow direction to the present-day Kongsfjorden cross-shelf trough took place during a glaciation at not, vert, similar1.5 Ma or probably later during an intensive major glaciation phase known as the ‘Mid-Pleistocene Revolution’ starting at not, vert, similar1.0 Ma. The seismic and bathymetric data suggest that the switch was abrupt rather than gradual and we attribute it to the reaching of a tipping point when growth of the Svalbard ice sheet had reached a critical thickness and the ice sheet could overcome a topographic barrier
