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
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

Milne-Edwards described Pericera coelata (A. Milne-Edwards, 1878: 224) based on two young females syntypes obtained from 10 meters deep off Idolos Island (îles Idolos) and near Havana, Cuba (MCZ 2848 and MCZ 2847, respectively). A. Milne-Edwards provided measurements for the female MCZ 2848 (cl 36 mm including rostrum, cw 27 mm); that female is herein designated as the lectotype of S. coelatus (cf. ICNZ, Art. 73.2.2. Recommendation 74F]. Therefore, the female MCZ 2847 is the paralectotype. With the designation of the lectotype of S. coelatus the type locality is restricted to “ 10 milles au nord des îles Idolos ” (cf. ICNZ, Art. 76.2), actually 16 miles north of Holbox Island. Rathbun (1925) considered Idolos Island a mistake for Jolbos Island. The specimen MCZ 2848 is labeled 16 miles north of Joblos Island, however we could not find neither of these localities. Calder (2013) faced a similar problem with the type locality of Obelia hyalina Clarke, 1879, a hydroid collected during the Blake Expedition whose type locality is "Zoblos Island”. In the narrative of the Blake Expedition there is indeed a reference to Joblos Islands: "… the north side of the Yucatan Bank to Alacran Reef, and from there in a south-east direction into 20 fathoms off the Joblos Islands …" (Agassiz 1888: ix). It may well be that Idolos, Joblos and Zoblos are probably errors for the Holbox Island, which is located at the northeastern tip of the Yucatan Peninsula, Mexico. The differences in the spelling of the island's name might have been introduced as a result of the variation in the way the name is pronounced (Calder 2013). There are also discrepancies about the distance between the Holbox island and the location from where the material was collected. A. Milne-Edwards (1879: 201) mentioned “... à 10 milles au nord des îles...”, whereas the type material was labeled “16 mis. North of Joblos Island”. Here we prefer to use the information on the label to determine the type locality of S. coelatus.Published as part of Colavite, Jessica, Santana, William & Tavares, Marcos, 2016, Morphological differences between Stenocionops furcatus (Olivier, 1791) and S. coelatus (A.

koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
