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

However, in the protologue of the species, Wallich (1820: 429) stated that “...I propose calling <i>Camellia kissi</i>, the <i>Newar</i> name being <i>Kissi</i> or <i>Kissi-soak</i> by enumerating the points on which their specific difference appears to me to rest”. It seems that the epithet is derived from the vernacular name and therefore, the original spelling of the epithet, <i>kissi</i>, should be retained (see Art. 60 Ex. 21 of the ICN).</p> <p> <b>Morphological notes</b>:— <i>Camellia thailandica</i> was simply compared with <i>C. brevistyla</i> (Hayata 1908: 63) Cohen-Stuart (1916: 67) on the size and shape of the leaves and flowers in the protologue (Chang & Ren 1991), and it is actually <i>C. kissi</i> based on its protologue and the types examined.</p> <p> <i>Camellia ligustrina</i> was not compared with a specific taxon of <i>Camellia</i> in the protologue (Orel <i>et al</i>. 2014). It was described as bearing a “finely hairy” seed, but the seeds of the holotype are glabrous (NSW900397 [image]). Based on the type and the photos reported (Orel & Curry 2015), <i>C. ligustrina</i> is treated as a heterotypic synonym of <i>C. kissi</i>. Orel <i>et al</i>. (2014: 310), however, established <i>Camellia</i> sect. <i>Pierrea</i> based on <i>C. ligustrina</i>, accordingly, this section is recognized as a heterotypic synonym of <i>Camellia</i> sect. <i>Paracamellia</i>.</p> <p> Similarly, Orel & Curry (2015: 182) did not compare <i>C. cuongiana</i> with other taxa of <i>Camellia</i> probably because they thought that it “possesses a combination of morphological characters which do not occur in any other known <i>Camellia</i> L. species”, and thus they established <i>Camellia</i> sect. <i>Lamdongia</i> based on it. However, the type and the photos in the protologue could clearly suggest that it is merely another representative of <i>C. kissi</i>. Therefore, sect. <i>Lamdongia</i> is treated as another heterotypic synonym of sect. <i>Paracamellia</i> in <i>Camellia</i>.</p>Published as part of <i>Zhao, Dongwei, 2022, Three new synonyms of Camellia kissi (Theaceae), pp. 83-84 in Phytotaxa 531 (1)</i> on pages 83-84, DOI: 10.11646/phytotaxa.531.1.8, <a href="http://zenodo.org/record/5843583">http://zenodo.org/record/5843583</a>
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
