Indeed, the preservation is usually excellent: the antennae, antennules and eyestalks of the specimens MNHN.F.

The dorsally preserved specimen MNHN.F.B13439 (Fig.9H) is also well-preserved and evidences delicate details on the carapace (branchiocardiac, postcervical and cervical grooves), telson (ponctuations and carinae).The other specimen (A33501; Fig. 9B) present some calcite bundles on the left chela.</p> <p>Superorder PERACARIDA Calman, 1904 Order MYSIDACEA Boas, 1883 Suborder and Family uncertain</p>Published as part of <i>Odin, Giliane P., Charbonnier, Sylvain, Devillez, Julien & Schweigert, Günter, 2019, On unreported historical specimens of marine arthropods from the Solnhofen and Nusplingen Lithographic Limestones (Late Jurassic, Germany) housed at the Muséum national d'Histoire naturelle, Paris, pp. 643-662 in Geodiversitas 41 (17)</i> on pages 654-658, DOI: 10.5252/geodiversitas2019v41a17, <a href="http://zenodo.org/record/3695414">http://zenodo.org/record/3695414</a>
Redécouverte du matériel type d’<i>Eryon cuvieri</i> Desmarest, 1817 (Crustacea, Decapoda, Eryonidae) et conséquences nomenclaturales
No full textEn 1817, Desmarest a décrit Eryon cuvieri, un nouveau crustacé du Jurassique supérieur de Bavière (sud de l’Allemagne). Plus tard, le même taxon a été décrit sous le nom de Macrourites arctiformis par von Schlotheim (1820). Ce taxon a ensuite été repris sous le nom d’Eryon arctiformis (von Schlotheim, 1820) par de nombreux auteurs qui ignoraient probablement le premier travail de Desmarest. Conformément au Principe de Priorité, il convient de reprendre le nom initial et le taxon Macrourites arctiformis von Schlotheim, 1820 est ici considéré comme un synonyme subjectif plus récent. Par ailleurs, deux spécimens de la série type d’Eryon cuvieri Desmarest, 1817, du Cabinet d’Histoire naturelle de Faujas de Saint-Fond, ont été récemment redécouverts dans la Collection de Géologie du Muséum national d’Histoire naturelle de Paris. Un lectotype est désigné ici.In 1817, Desmarest erected Eryon cuvieri, a new crustacean from the Late Jurassic of Bavaria (southern Germany). Later, the same taxon was described as Macrourites arctiformis by von Schlotheim (1820). Subsequently, numerous authors, probably unaware of Desmarest’s first paper, referred to this taxon as Eryon arctiformis (von Schlotheim, 1820). Following the Principle of Priority, the original name must be used and Macrourites arctiformis von Schlotheim, 1820 is here considered to be a more recent, subjective synonym. Moreover, two specimens of the type series of Eryon cuvieri Desmarest, 1817, from Faujas de Saint-Fond’s Cabinet of Natural History, have recently been traced in the Collection de Géologie of the Muséum national d’Histoire naturelle, Paris. A lectotype is herein designated.</p
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
