No full textFig. 6.1. Shell digitised with different methods. The photogrammetry model was captured with a 100 mm Macro lens and processed with Agisoft Photoscan. The visual comparison of the mollusc shows a similar level of detail between photogrammetry and MechScan for the external surfaces, with still a bit more detail for the MechScan. The HDI Advance has a much lower resolution.Published as part of Brecko, Jonathan & Mathys, Aurore, 2020, Handbook of best practice and standards for 2D+ and 3D imaging of natural history collections, pp. 1-115 in European Journal of Taxonomy 623 on page 86, DOI: 10.5852/ejt.2020.623, http://zenodo.org/record/375133

No full textFig. 6.14. Ishango rod. The left 3D model was acquired with a µCT many years ago. The middle one is scanned with the MechScan structured light scanner. The right one is the combination of both the µCT scan, the structured light scan and the texture of the photogrammetry model.Published as part of Brecko, Jonathan & Mathys, Aurore, 2020, Handbook of best practice and standards for 2D+ and 3D imaging of natural history collections, pp. 1-115 in European Journal of Taxonomy 623 on page 96, DOI: 10.5852/ejt.2020.623, http://zenodo.org/record/375133

No full textFig. 2.17–2.18. Two different designs of the ZooSphere. In the first (left) figure, the stepper motor is centered on a long U-shaped axis, a swing, which is controlled by the second axis. In the second figure (right) all of this is more compressed in space and instead of a U-shaped axis to mount the first stepper motor, it is attached to the second by means of a T-shaped rod.

Mathys leg.; BE_RMCA_MYR.Dip.22930. Remarks In the original description of the species, the length unit given for the specimens’ sizes is wrong and should have been cm instead of mm. Correct measurements are: length ♂♂: 3.4–8.0 cm; ♀♀: 5.0– 7.0 cm; midbody width 0.34–0.5 cm and 0.3 – 0.5 cm, respectively. Taking this modification into account, the recently collected specimens agree with the description (VandenSpiegel & Golovatch 2007).Published as part of Vandenspiegel, Didier, Henrard, Arnaud & Mathys, Aurore, 2021, Sechelleptus arborivagus sp. nov., a new arboreal spirostreptid millipede (Diplopoda, Spirostreptidae) endemic to Mayotte Island (Comoros Archipelago), Indian Ocean, pp. 1-21 in European Journal of Taxonomy 755 (1) on pages 7-8, DOI: 10.5852/ejt.2021.755.1395, http://zenodo.org/record/496600
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
