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
Le régime alimentaire de Macaca sylvanus dans différents habitats d’Algérie : II. Régime en forêt sempervirente et sur les sommets rocheux
No full textThe diet composition of two troops of Macaca sylvanus has been studied in two different habitats of the Djurdjura National Park (Algeria).
1. — In the evergreen Cedar-Green Oak forest (Tigounatine Range), quantitative observations were carried out during 16 months (April 1983 to March 1985).
2. — On the rocky ridges of the Icetcifène Range, without any arborescent vegetation, only qualitative observations were made during 12 months (April 1983 to August 1984).
On the Tigounatine Range, the troop spent 93 % of its time feeding on plant foods, from which 75 % were leaves and seeds.
Great seasonal variations were observerd : Barbary Macaques ate mainly grass and / or Cedar leaves in spring and winter. They turned to a granivorous diet in summer and autumn, consumming mainly acorns and Asphodelus microcarpus seeds. They can become insectivorous in spring, when caterpillars are swarming.
These Barbary macaques spent 75 % of their feeding time on the ground. Throughout the year, young animals (0,5-3 years) and subadults (3-4 years) spent more time feeding in trees than adults (> 4 years), but the kind of food items eaten remained similar. Adults ate preferentialy fallen acorns and caterpillars creeping on the ground, whereas young macaques gathered both acorns and caterpillars in trees.
One hundred thirty six food categories were identified in the Barbary Macaques diet : however, only Quercus ilex, Cedrus atlantica, Asphodelus microcarpus, nine grass species and caterpillars contributed to 62 % of the diet. Furthermore, only one or three species (out of the 12 to 52 consumed each month) contributed to 43 to 85 % of the diet.
Fifty nine percent of the food items originated from the grass layer, and 34 % from the arboreal layer.
On the Icetcifène range, the troop’s diet was mainly made of plant material. The Barbary Macaques fed on 31 plants species and 3 animal prey. In this habitat, Barbary Macaques were essentialy terrestrial.Le régime alimentaire de Macaca sylvanus a été étudié dans le Parc National de Djurdjura (Algérie) :
1. — Pour une troupe occupant une forêt sempervirente de Cedrus atlantica et Quercus ilex sur le mont Tigounatine durant 16 mois répartis d’avril 1983 à mars 1985 ; les résultats sont quantitatifs.
2. — Pour une troupe vivant sur les sommets rocheux (Mont Icetcifène) durant 12 mois répartis d’avril 1983 à août 1984 ; les résultats sont uniquement qualitatifs.
Sur le Tigounatine, les végétaux représentent 93 % des prises alimentaires de la troupe, par ailleurs essentiellement folivore-granivore (75 %).
On note d’importantes variations saisonnières et annuelles du régime alimentaire : au printemps et en hiver, le Magot est principalement folivore, consommant en abondance des feuilles d’herbacées et / ou de cèdre ; en été et en automne, il devient granivore, recherchant surtout les glands et les graines d’asphodèles ; il peut également devenir carnivore certaines années au printemps, lors de la pullulation des chenilles phytophages.
Ce singe passe 75 % de son temps de recherche alimentaire au sol.
Globalement les jeunes sont un peu moins folivores que les adultes. Les principales différences de mode d’utilisation des ressources entre les classes d’âge sont surtout liées, quelque soit la période de l’année, au niveau de collecte. Les jeunes (0,5-3 ans) et les subadultes (3-4 ans) se montrent près de deux fois plus arboricoles que les adultes (> 4 ans) au cours de leur recherche alimentaire. Les adultes mangent préférentiellement les glands tombés au sol et les chenilles lorsqu’elles se déplacent à terre, alors que les jeunes les cueillentMénard Nelly, Vallet Dominique.
