FIGURE 4. A in Syngraph: An application for graphic display and interactive use of synonym lists
No full textFIGURE 4. A synonymy is represented as a three-branch relation using a solid black line to the left of the names. The two names the authority considered related are linked to the name the authority considered valid, indicated by a black box, which is followed, at the end of the line, by the name of the authority and the bibliographic citation to the source of the information. The relation shown here should be read: Carlgren (1928) considered Dimyactis duplicata Pax, 1922, to be a junior synonym of Edwardsia kerguelensis Studer, 1879, under the new combination Halianthella kerguelensis (Stud.).Published as part of Ardelean, Adorian, Kervin, Karina, Kansakar, Suman & Fautin, Daphne Gail, 2009, Syngraph: An application for graphic display and interactive use of synonym lists, pp. 29-39 in Zootaxa 2283 (1) on page 33, DOI: 10.11646/zootaxa.2283.1.3, http://zenodo.org/record/530991
FIGURE 9 in Syngraph: An application for graphic display and interactive use of synonym lists
No full textFIGURE 9. Confidence in a relation is represented as a symbol imposed on the box indicating the name considered valid. A) illustrates a questionable synonymy for Cerianthus vermicularis (E. Forbes), and B) illustrates a questionable synonymy for Cerianthus lloydii Gosse, 1859. Both relations should be read: Gosse (1860) indicated the possible synonymy of Cerianthus vermicularis (Forbes in Johnston, 1847) with Cerianthus lloydii Gosse, 1859. In B, the name Cerianthus vermicularis (E. Forbes) Gosse, 1860, is imposed on white; this name is not part of the synonymy of C. lloydii, but is listed in Syngraph because the name C. lloydii has questionably been applied to C. vermicularis. Note that the line for Cerianthus vermicularis (E. Forbes) Gosse, 1860, contains two question marks that should not be confounded: that after the name vermicularis was introduced by the authority in the cited publication to signify the authority's uncertainty about the name, whereas that on the box of the lead line is the convention in Syngraph for such uncertainty (which is not as obvious in some citations as it is in this one).Published as part of Ardelean, Adorian, Kervin, Karina, Kansakar, Suman & Fautin, Daphne Gail, 2009, Syngraph: An application for graphic display and interactive use of synonym lists, pp. 29-39 in Zootaxa 2283 (1) on page 36, DOI: 10.11646/zootaxa.2283.1.3, http://zenodo.org/record/530991
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

A new species of the sea anemone *Megalactis* (Cnidaria: Anthozoa: Actiniaria: Actinodendridae) from Taiwan and designation of a neotype for the type species of the genus
No full textAsterisks (*...*) surround words or phrases that are to be italicized.*Megalactis comatus*, new species, from Taiwan is the third species in this genus of sea anemones with highly branched tentacles. The others are *M. hemprichii* Ehrenberg, 1834, from the Red Sea, and *M. griffithsi* Saville-Kent, 1893, from the Great Barrier Reef. Size of nematocysts from acrospheres and column clearly separate *M. comatus* from the other species of *Megalactis*. One of us (A.A.) observed asexual blastulae in *M. comatus*. This is the first record of asexual reproduction in the genus. Because type specimens of *M. hemprichii* have not been found and the original description cannot be used to distinguish this species from other species of *Megalactis*, we designate a neotype for the type species of the genus, *M. hemprichii* Ehrenberg, 1834. All the specimens of actinodendrids examined lacked basilar muscles; this calls into question the placement of family Actinodendridae among thenarian sea anemones
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
