Type species: Yania sinica Huang, 1997. Yanoancistroides Huang, 1999: 516. (syn. nov.) 1. * Corresponding author: Tel. + 8620 8528 3518, E-mail address: [email protected] Adults medium sized. Palpi with third segment long and thin. Both wings with vein M 2 straight and about midway between veins M 1 and M 3 at their origin. Externally the genus strikingly resembles Iambrix, but can be distinguished by male genitalia with uncus deeply bifurcated and hindwing underside without silvery white spots. Distribution.

The species was well illustrated by Huang (1997, 2003), according to palpi, wing pattern and male genitalia, it is similar to I. fujianana, but can be easily separated from the latter by hindwing underside dark brown, almost uumarked, valva with the ampullar and harpal processes widely separated at apex, the harpe with outer margin straight bearing a small spines centrally and well pointed apically. So, the species definitely belongs to Idmon. Distribution.

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
Idmon fujianana Chou & Huang 1994, comb. nov.
No full textIdmon fujianana (Chou & Huang, 1994) comb. nov. Astictopterus fujiananus Chou & Huang, 1994: 721. (Type locality: Fujian) Astictopterus fujiananus: Huang (ed.), 2001: 139. Yanoancistroides fujiananus: Huang & Wu, 2003: 136 -140. The species was originally described under the genus Astictopterus, based on a femele specimens. Huang and Wu (2003) examined additional one male specimens, and transfered the species to Yanoancistroides. According to their illustration, e.g., palpi with third segment long and thin; both wings with vein M 2 straight and about midway between veins M 1 and M 3 at their origin, upperside unmarked, uniform dark brown in color, without secondary characters, underside hindwing ground color brown, with dark brown spots in spaces Cu 2 to Sc+R 1 and the end of the cell, discocellular margined yellow; male genitalia with uncus deeply bifurcated, valva with the ampullar and harpal processes contacted completely at apex, the species is belonging to Idmon. Distribution.

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
