Introduction
No full textThis is a preliminary synthesis of excavations at La Quina from 1985 through 1994. The report is interim in nature, since only a portion of the very rich material has been studied. These recent excavations were intended to address certain questions left unresolved by the excavations conducted by G. Henri-Martin from 1952 through 1972 : first to establish a detailed stratigraphy of the sediments, to understand the mechanisms and circumstances of their deposition, and to collect informations about the extent of the remaining deposits ; then to define the chronology of these formations in terms of absolute dates and to determine the palaeoenvironments in which people lived at La Quina ; at last to develop a detailed understanding of the material culture and human activities at the site. The stratigraphy and depositional regime were recorded and analyzed. The lithic industries are all Mousterian : Denticulate Mousterian and Mousterian of Acheulian Tradition in the upper levels, and Quina Mousterian in the lower and intermediate levels. In spite of the small volume of sediment excavated, one anthropogenic structure (a pit) was uncovered. Its function is not yet understood. In terms of palaeontology, there is a certain monotony in the species present : bovines (Bos and Bison), horse, and reindeer. Only their relative frequencies vary significantly in different levels of the profile. These species indicate an open environment, which contradicts the first palynological studies. The zooarchaeological studies are not yet completed, but interesting results are available regarding the reindeer from the site, which are represented by distal limb bones (indicating marrow extraction), and the horses, which are represented in the upper levels primarily by fragments of skull and pelvis.
In terms of human palaeontology, we underline the discovery of a fragment of a child's frontal bone and of a portion of an adult calotte in the lower beds (Quina Mousterian), as well as several teeth.Cet article présente une synthèse provisoire des fouilles effectuées à La Quina de 1985 à 1994 ; une partie seulement du très riche matériel recueilli ayant été étudiée. Ces nouvelles fouilles avaient pour but de résoudre un certain nombre de problèmes laissés en suspens au terme des fouilles conduites par G. Henri-Martin, de 1952 à 1972. Il fallait, tout d'abord, établir une stratigraphie détaillée des dépôts, comprendre les phénomènes de leur mise en place et obtenir des données sur l'importance des sédiments encore en place ; puis, préciser la chronologie de ces formations en termes de datations absolues et définir les paléoenvironnements des hommes de La Quina ; enfin, obtenir une connaissance détaillée des cultures matérielles et des activités humaines.
La stratigraphie a été précisée ainsi que la mise en place des dépôts. Les industries se rapportent uniquement au Moustérien : Moustérien à denticulés et Moustérien de tradition acheuléenne dans les niveaux supérieurs, Moustérien de type Quina dans les niveaux médians et inférieurs. Malgré le petit volume de sédiments fouillés, une structure anthropique (fosse) a pu être mise en évidence dont la fonction n'a pas encore été définie. Sur le plan paléontologique, on remarque une certaine monotonie dans les espèces présentes : Bovinés (Bos et Bison), Cheval et Renne. Seuls leurs taux relatifs présentent des modifications sensibles de haut en bas du profil. Ces espèces indiquent un paysage ouvert, ce qui est en contradiction avec les premières études palynologiques. Les études archéozoologiques ne sont pas encore terminées, mais déjà des résultats intéressants peuvent être mentionnés en ce qui concerne le Renne dont on note une surreprésentation des parties distales des pattes (recherche de moelle) et le Cheval qui est essentiellement représenté dans les niveaux supérieurs par des restes crâniens et des fragments de bassin.
Sur le plan de la paléontologie humaine nous insisterons ici sur la mise au jour, outre de quelques dents, d'un fragment de frontal d'enfant et d'une portion de calotte crânienne d'adulte dans les niveaux inférieurs (Moustériens de type Quina).Debénath André, Dibble Harold Lewis.

The Mousterian Industry from Bisitun Cave (Iran)
No full textBisitun, a Middle Paleolithic cave site in northwestern Iran, was excavated over thirty years ago by C. Coon. Its Mousterian industry, as later described by Skinner, has been thought to be characteristic of other Mousterian industries from that region, what is generally called the Zagros Group Mousterian. The present analysis shows that the Bisitun industry contains some important features that were overlooked by Skinner, including a high frequency of Levallois technique and several truncated-faceted pieces. Because these features have not yet been recognized in other Zagros Mousterian industries, their presence here raises the question of the distinctiveness and homogeneity of this Mousterian Group.Bisitun, site en grotte du Paléolithique Moyen du N. О. de l'Iran fut fouillé il y a plus de trente ans par C. Coon. Son industrie moustérienne, telle qu'elle fut décrite par la suite par Skinner, semblait présenter tous les caractères des autres industries moustériennes de la région, généralement nommées le « Groupe moustérien du Zagros ». Un nouvel examen de cette industrie a permis de montrer que l'industrie de Bisitun présente plusieurs traits non décelés par Skinner : haute fréquence de la technique Levallois et présence de pièces tronquées facettées. Ces caractères n'ayant pas été reconnus dans les autres industries moustériennes du Zagros, leur présence soulève la question de la validité de la distinction de ce groupe moustérien et de son homogénéité.Dibble H.

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

Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
