Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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

Contribution à l'étude de la stratigraphie des lœss dans le N.-E. du Bassin de Paris
The authors have studied a representative quarry section of the loessic loamy cover in the N.E. par of the Paris basin. Different methods have been used : morphological description, particle size distribution study, physico-chemical and mineralogical analysis, micromorphological examinations, lithic industries study. Several differents layers of loam are present, two from the recent loess cycle and the other from older one. A brown leached soil is developped in the surface cover and overlies the remains of a soil of leached type. Below those two layers of the recent cycle, one may observe an old loess with a brown-reddish very clayey argillic horizon. Between recent and old loess typical « mousterien » industries of the « acheuleen » traditional type, have been found. A hypothesis concerning the loess stratigraphy has been made. The upper sediments should belong to the recent loess cycle : wurm deposits, although the reddish buried loam should consist of a paleosol from the old cycle, and developped during the interglacial riss/würm period. A detailed soil mapping of the region permits the generalization of that interpretation to a great part of the north-east extension of the loessic loamy formations in the Paris basin.Une coupe limoneuse représentative de la couverture loessique de la région du Marlois, dans la partie N-E du Bassin de Paris, est étudiée en détails à l'aide de différentes techniques, dont certaines spécifiquement pédologiques. Après une description morphologique de la coupe sont présentés et commentés les résultats des déterminations granulométriques, physico-chimiques, minéralogiques et micromorphologiques, ainsi que ceux correspondant à l'examen des industries lithiques récoltées. Plusieurs niveaux de limons sont différenciés, les deux premiers appartenant au cycle des lœss récents, les autres constituant des limons plus anciens. Un sol brun lessivé est développé dans la couverture de surface, ce dépôt surmontant les vestiges d'un sol du type lessivé dont l'évolution date vraisemblablement d'un interstade de la dernière période de glaciation, et dont les éléments constitutifs ont été partiellement remaniés par les phénomènes d'érosion. Ces matériaux reposent sur un limon plus ancien dont la partie supérieure constitue un horizon d'accumulation brun rougeâtre très argileux. Les deux principaux types de formation que nous venons de citer sont séparés par un niveau d'industries typiques de la période de transition cycle récent - cycle ancien : moustérien de tradition acheuléenne à faciès levallois, et possèdent des caractères sensiblement différents. On constate pour les plus récents : teneur en argile moyenne, peu de sables, association de minéraux lourds des lœss récents, présence de vermiculite, développement pédogénétique modéré ; pour le limon plus ancien : teneur en argile importante et teneur en sable plus élevée, minéraux lourds de métamorphisme abondants, dominance de minéraux argileux gonflants de type montmorillonitique, caractères pédogénétiques accentués. L'ensemble de ces résultats permet d'avancer une hypothèse concernant la stratigraphie des matériaux étudiés. Les niveaux supérieurs appartiendraient donc au cycle des lœss récents : dépôts würmiens, tandis que le limon rougeâtre enfoui constituerait un paléosol du cycle ancien développé lors de l'inter-glaciaire Riss/Würm. Les travaux de cartographie détaillée des sols réalisés dans la région permettent de généraliser cette interprétation à l'ensemble du Marlois, et à une grande partie de l'extension N-E des formations limoneuses en bordure du Bassin de Paris.Jamagne M., Mathieu Clément.
