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
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

Nesophrosyne
No full text<i>Nesophrosyne</i> and <i>Nesoreias</i> <p> We examined wing venation in a total of 1085 specimens, in at least 107 distinct morphological species from across the Hawaiian Archipelago (See Appendix 1 for annotated list of species examined). The examined specimens confirm that wing venation is highly variable not only within the genus, but also within species and even single individuals. Presence of the outer anteapical cell is the most common state, however variation in the size, shape, and presence (in one or both wings) is common in large populations. In some rare instances, the cell is subdivided with individuals having up to four outer anteapical cells. The character’s extreme variability demonstrates the lacking predictive, evolutionary functionality necessary to define a cohesive subgenera, or taxonomic grouping. Thus, the outer anteapical cell cannot be used to differentiate subgenera of <i>Nesophrosyne</i>.</p> <p> Molecular phylogenetic analyses reveal <i>Nesoreias</i> as polyphyletic, falling out in at least three clades (data not shown). <i>Nesophrosyne eburneola</i> Osborn 1935 and <i>N. marginalis</i> Osborn 1935 are placed as sister species with high support, however <i>N. insularis</i> Kirkaldy 1910 and <i>N. sp.1</i> are nested well within two different clades with high support. The distribution of species with individuals without cells, with one cell, or with extreme size variation is random across the tree with high support for some groups. These molecular data, coupled with genus-wide morphological assessment, indicate that the subgenus <i>Nesoreias</i> is dubious and we synonymize it with <i>Nesophrosyne.</i></p>Published as part of <i>Bennett, Gordon M & O'Grady, Patrick M, 2011, Review of the native Hawaiian leafhopper genus Nesophrosyne (Hemiptera: Cicadellidae: Deltocephalinae) with description of eight new species associated with Broussaisia arguta (Hydrangeaceae), pp. 1-25 in Zootaxa 2805</i> on page 5, DOI: <a href="http://zenodo.org/record/207804">10.5281/zenodo.207804</a>
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
