No full textFamily Permoridiidae fam. nov. urn:lsid:zoobank.org:act:C6E7BB19-1626-4429-9C8CE85BA2FB9D44 Type genus: Permoridium gen. nov. Diagnosis As for the type genus, by present designation and monotypy. Genus Permoridium gen. nov. urn:lsid:zoobank.org:act:DCBE88A6-3413-4EB9-8126- 1ABF8E088433 Type species: Permoridium fresenaci sp. nov., by present designation. Etymology Composed of the stem of ‘Perm-ian’ and the suffix of ‘Pelo-ridium’, referring to the age and putative phylogenetic relationship of the new genus, the Permian period and the genus Peloridium, respectively. Gender neuter. Diagnosis Forewing characters only. Vein M+CuA basally separated from R but appressed to it (main autapomorphy); ScA elongate, well separated from C, with posterior branches; ScP well separated from R and elongate, ending into RA in distal half of wing; stem of CuA weak; crossvein cua-cup strong and aligned with distal part of CuA; CuP weak, closely parallel to cua-cup, distal part of CuA and PCu.Published as part of Burckhardt, Daniel, Nel, André, Raisch, Manfred & Poschmann, Markus J., 2022, A new putative moss bug (Insecta: Hemiptera) from the lower Permian of the Saar-Nahe Basin, SW Germany, and the age of Coleorrhyncha, pp. 1-6 in Historical Biology 7 (2) on page 3, DOI: 10.1080/08912963.2022.2067759, http://zenodo.org/record/774569
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
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
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
