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
À propos de l’acte de vente de janvier 1291 : Neuf-Marché-en-Lyons, radiographie d’une châtellenie normande
No full textLes quatre châtellenies-verderies de la forêt de Lyons aux XIIIe-XIVe siècles. Encore identifiable sur la carte de Cassini par la mention « un des quatre anciens châteaux de Lyons », la châtellenie du Neuf-Marché – à la différence de celle de Lyons, de Beauvoir ou encore celle de Longchamps – n’a pas toujours relevé au Moyen Âge du domaine royal de Lyons-la-Forêt. Ainsi s’explique cet acte de vente de la châtellenie du Neuf-Marché qui permet, à son acquéreur le roi de France Philippe le Bel, ..
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
Une "forêt" royale au Moyen Age : Le pays de Lyons, en Normandie (vers 1100 - vers 1450)
No full textAlthough the forest of Lyons is often defined simply as a border forest, ten years of research has enabled me to make a radical change to this old geographical definition. My reconsideration of even the concept of “forest,” shows that, in the High Middle Ages, the word meant not large stretches of woodlands but, instead, a well-developed space, where timberlands, thickets, heaths, pastures, cultivated fields, and villages coexisted. The medieval forest of Lyons, the most important in all Normandy with its 30,000 hectares, was entirely devoted to the use and necessities of its ducal or royal title-holder, and it emerged as a pays formed by the coalescence of four distinct spaces between 1100 and 1450. The many sojourns of the Plantagenets and then the Capetians — due to hunting (residential space) and various wars (military space) — are documented by more than 500 acts signed in the forest of Lyons between 1100 and 1400. These sojourns produced a political space that explains the stunning careers of at least two royal favorites, natives of the pays of Lyons: William Longchamp, chancellor under Richard the Lionheart, and Enguerrand de Marigny, chief minister of Philip the Fair. Since wood was a necessity in medieval times, the forest of Lyons was also an important economic space because it earned significant revenue for its title-holder. All things considered, it is clear that the pays of Lyons produced a true ecosystem able to survive all hardships until the dark, final period of the Hundred Years War put an end to the Golden Age that the Middle Ages had brought to the forest of Lyons.Alors que la forêt de Lyons est souvent assimilée à une simple forêt-frontière, dix années d’enquête nous obligent à modifier radicalement cette définition géo-historique. Il faut dire qu’entre temps, il a fallu reconsidérer la notion même de forêt qui désignait au haut Moyen Âge, non pas de grandes étendues boisées, mais tout au contraire un espace fortement humanisé où coexistent futaies et taillis, landes et prairies, champs et villages. De cette grande forêt médiévale de Lyons – la plus importante de Normandie avec ses 30 000 ha – entièrement dévolue à l’usage et aux besoins de son détenteur ducal ou royal se dégage alors un pays, lui-même fruit de la sédimentation de quatre espaces nettement identifiés, entre 1100 et 1450. Des multiples séjours des Plantagenêts puis des Capétiens, attestés par plus de 500 chartes signées en forêt de Lyons entre 1100 et 1400 et justifiées soit par la chasse (espace résidentiel), soit par la guerre (espace militaire) résultent en effet un espace politique qui explique la fortune étonnante d’au moins deux favoris issus du pays de Lyons : Guillaume de Longchamps, chancelier d’Angleterre sous Richard Cœur de Lion et Enguerrand de Marigny, le familier de Philippe le Bel. S’ajoutent à cela tous les revenus qu’un espace économique comme la forêt de Lyons procure à son détenteur, en se rappelant l’importance prise par le bois dans l’économie médiévale. En définitive, l’on découvre ainsi que ce pays a fini par produire un véritable écosystème d’une résilience à toute épreuve jusqu’à ce que les années sombres de la fin de la Guerre de cent ans finissent par avoir raison de cet âge d’or qu’a représenté le Moyen Âge pour la forêt de Lyons
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
A royal forest in the Middle Ages : The pays de Lyons in Normandy (circa 1100 - circa 1450)

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
