Montrouzier, Touho Channel, lagoon, 35 m, commensal with Alcyonacea, 17 Sep. 1993, 1 male CL 3.5 mm. Remarks. This species was redescribed in detail by Osawa (1998 b). Lissoporcellana nakasonei closely resembles L. miyakei Haig, 1981, but differs in having subparallel instead of strongly convex branchial margins of the carapace. Distribution. This species was recorded only from southern Japan (Izu Islands; Kii Pesinsula, Amakura in Kyushu, Ryukyu Islands) at depths of about 20 m on rocky substrates and in association with alcyonacean octocoral, Dendronephthya nipponica Utinomi and Dendronephthya sp. (Osawa 1998 b; Kato & Okuno 2001; Osawa & Fujita 2005). This is the first record of L. nakasonei from outside of Japan and from New Caledonia at the depth of 35 m.Published as part of Osawa, Masayuki, 2007, Porcellanidae (Crustacea: Decapoda: Anomura) from New Caledonia and the Loyalty Islands, pp. 1-49 in Zootaxa 1548 on page 13, DOI: 10.5281/zenodo.17804

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe 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

Known only from Japan; Boso Peninsula of Honshu mainland to Satsuma Peninsula of southern Kyushu, and Izu Islands. The holotype was collected from off Okino-shima, northern Kyushu, at a depth of 90 m (Miyake & Baba 1968). The specimens examined were obtained at depths of 10– 40 m.</p> <p> <b>Habitat and ecology</b>. This species is found on soft and black corals (Alcyonacea and Antipatharia) or sponges (Minemizu 2000, 2002; Kato & Okuno 2001).</p> <p> The ecology of <i>C. ortmanni</i> (as <i>C. dolichopus</i>) is noted in detail by Ogawa & Matsuzaki (1987). The authors suggested that the lifespan of the female is about one year based on the rearing under laboratory conditions.</p> <p> <b>Remarks</b>. The holotype of <i>Chirostylus ortmanni</i> was not available for study. The specimen was previously deposited in the Zoological Laboratory, Faculty of Agriculture, Kyushu University (ZLKU), and now is supposedly transferred to the Kitakyushu Museum of Natural History and Human History, together with numerous crustacean specimens described by Dr. S. Miyake and his co-workers. However, the attempt to find the holotype of <i>C. ortmanni</i> in the collection of the museum was not successful (Dr. M. Shimomura; personal communication).</p> <p> The morphology of the specimens examined in this study agrees well with the original description of <i>C. ortmanni</i> by Miyake & Baba (1968) in most diagnostic aspects. The above description complements their account of the species. Miyake & Baba (1968) also mentioned that their live specimen of <i>C. ortmanni</i> had two reddish orange bands on the distal portions of the P2–4 meri. This characteristic marking is distinct in the photograph of a live specimen shown by Minemizu (2000, 2002) and was also confirmed in the specimens examined from Boso Peninsula and Hachijo-jima Island.</p> <p> Osawa & Nishikiori (1998) concluded that the specimens identified as <i>C. dolichopus</i> (NSMT-Cr 11672– 11686) by Ogawa & Matsuzaki (1993) are referable to <i>C. ortmanni</i>. The specimens were re-examined for the above description and support their conclusion. Accurate identification of a specimen from Aka-jima Island in the Ryukyus (cl 1.6 mm, NSMT-Cr 11686) is difficult since it is a juvenile. Judging from its locality, the specimen probably belongs to <i>C. stellaris</i> n. sp., described below.</p> <p> Specimens in color photographs identified by Miyake (1982, 1991, 1998), Takeda (1986, 1994), and Asakura (1995) as <i>C. dolichopus</i> can be referred to <i>C. ortmanni</i>. They all have the color pattern characteristic of <i>C. ortmanni</i>. The illustration of <i>C. dolichopus</i> shown by Miyake (1960, pl. 48, fig. 8) also seems to agree with the coloration of <i>C. ortmanni</i>. However, Miyake and Baba (1968: 383) noted that “The coloration and some characters of the present material (of <i>C. dolichopus</i>) are previously shown by Miyake (1960) ”. The correct specific identification of Miyake’s (1960) specimen is difficult without re-examination. The morphological distinctions between <i>C. dolichopus</i> and <i>C. ortmanni</i> are cited in key to species of the genus provided by Osawa & Nishikiori (1998) and Baba (2005).</p>Published as part of <i>Osawa, Masayuki, 2007, A new species of Chirostylus Ortmann, 1892 (Crustacea: Decapoda: Anomura: Chirostylidae) from the Ryukyu Islands, southwestern Japan, with a supplemental description of Chirostylus ortmanni Miyake & Baba, 1968, pp. 31-43 in Zootaxa 1450</i> on pages 32-36, DOI: <a href="http://zenodo.org/record/176238">10.5281/zenodo.176238</a>
Dispelling the Myths Behind First-author Citation Counts
No full textWe 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
