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
Cassia aversiflora Herb., Bot. Mag.
No full text2. Cassia aversiflora Herb., Bot. Mag. 53: t. 2638. 1826. Type:— BRAZIL. Cultivated from Brazilian seeds (lectotype designated here: Plate 2638 [illustration!], in Bot. Mag., 1826. Lectotype available at: https://www.biodiversitylibrary.org/page/488850#page/85/mode/1up. Epitype: BRAZIL. Bahia, Estrada de Joazeiro, 22 Oct 1967, fl. and fr., A.P. Duarte 10552 NY00582685 [image!], designated here). Image of epitype available at: http://sweetgum. nybg.org/science/vh/specimen-details/?irn=445065 Accepted name. Senna aversiflora (Herb.) H.S. Irwin & Barneby (1982: 529). Notes. Cassia aversiflora was described and illustrated by Herbert in Sims (1826: plate 2638), based on a collection of seeds from Brazil. No information was provided about the type material in the original description, and we did not find any other specimens that could represent the original material. As such, we are designating the illustration of Herbert in Botanical Magazine, plate 2638, as the lectotype. We also feel the need to designate an interpretive type, since the illustration provided by Herbert does not include the fruits (an important character for Senna aversiflora). We are therefore designating here the specimen deposited at the New York Herbarium (NY), under barcode NY 00582685, as the epitype, according to Art. 9.9 of ICNB (Turland et al. 2018).Published as part of Souto, Flávio Sousa & Agra, Maria De Fátima, 2022, Typifications of ten names related to Senna ser.

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

No full text9. Cassia semifalcata Vell., Fl. Flumin. T 4: 167. 1829. Type:—“Habitat silvis maritimis” (lectotype designated here: tab. 68, T. 4 [illustration], in Fl. Flumin. T.4. 1831[“1827”]). Lectotype available at: https://digital.bbm.usp.br/view/?45000009111&bbm/4266#page/70/mode/2up Accepted name. Senna multijuga subsp. lindleyana (Gardner) H.S. Irwin & Barneby (1982: 498). Notes. Cassia semifalcata was proposed as a new species by Vellozo (1829: 167) without any indication of the holotype. As such, and following the recommendations of articles 9.11 and 9.12 of the ICNB (Turland et al. 2018), we are designating the illustration presented by Vellozo tab. 68, in Fl. Flumin., T. 4, 1831[“1827”]) as the lectotype of Cassia semifalcata, as that illustration contemplates all of the characters presented in the protologue, no type material was referred to in the original description, and no specimen used by Vellozo has been located.Published as part of Souto, Flávio Sousa & Agra, Maria De Fátima, 2022, Typifications of ten names related to Senna ser.

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

Lectotype available at: https://kiki.huh.harvard.edu/databases/specimen_search. php?mode=details&id=50513 Accepted name. Senna huancabambae (Harms) H.S. Irwin & Barneby (1982: 561). Notes. The protologue of Cassia huancabambae indicates the collection A. Weberbauer 6285 as the type material. The holotype deposited at the Berlin Herbarium (B), however, was probably destroyed during World War II, although a photograph of the specimen is available in the negatives collection of the Field Museum (F), under number F-1693. We located six specimens labeled A. Weberbauer 6285, and we are designating here the specimen under barcode GH00053175 deposited at the Gray Herbarium of Harvard University (GH) as the lectotype, as it is complete and shows leaves, flowers, and fruits.Published as part of Souto, Flávio Sousa & Agra, Maria De Fátima, 2022, Typifications of ten names related to Senna ser.
