Ophiusini

Synonymy: Anuini Wiltshire 1976; Lagopteridae Kirby 1897; Lagopterini Berio 1992; Ophiusidae Herrich-Schäffer 1845 [1851]; Ophiusidae Guenée 1852; Ophiusini Wiltshire 1992 Type genus: Ophiusa Ochsenheimer, 1816 Type species: Phalaena tirhaca Cramer, 1777 Molecular studies have changed the composition of the Ophusini considerably since its treatment by Goater et al. (2003) in which he considered the Ophiusina as one of numerous Catocalini subtribes. Ophusina of Goater et al. (2003) contained several genus groups: Catephia, Cerocala, Ophiusa, Parallelia, and Zethes-Pericyma. The Ophiusa genus group contained Clytie, Minucia, Ophiusa, and Thyas, and was defined by characters of the male and female genitalia. In the phylogeny of Zahiri et al. (2012), Artena Walker, Clytie, Thyas Hübner grouped with Ophiusa (BP=100). Zahiri et al. (2012) remarked that that species belonging to this clade possess probosces significantly modified with enlarged spines and erectile hooks used for fruit piercing and lachrymal feeding. Holloway (2005) divided the Ophiusini into three groups, which reflect the currently recognized Euclidiini, Ophiusini, and Poaphilini. Holloway (2005) included Artena, Ophiusa, and Thyas in the subset of the tribe reflecting the current Ophiusini, distinguishing them by the absence or reduction of coremata on the male valvae, a secondary loss of the pupal bloom, and similarities in forewing pattern. Kononenko (2010) followed Holloway’s (2005) broader concept of the Ophiusini, and included Siberian species of Artena, Bastilla Swinhoe, Clytie, Dysgonia, Grammodes, Minucia, Ophiusa, Thyas and Serrodes in the tribe. Likewise, Kononenko & Pinratana (2013) did not distinguish the Poaphilini from the Ophiusini in their catalogue of Thai Erebidae, placing The “Phylum of Anua ” of Berio (1959) contains members of this the Ophiusini, which he united by the location of the androconial groove on the femur and trochanter, and a spined femora. The “Phylum of Anua ” contained members of the current genera Clytie, Euminucia Hampson, Hypanua Hampson, Ophiusa, and Thyas. Klyuchko (1978) identified several characters shared by some taxa in this tribe and the closely related Poaphilini. She noted that the frons of Anua [Ophiusa], Ophiusa and Dysgonia Hübner [Poaphilini], along with Eccrita Lederer [Lygephila, Toxocampinae] share a distinctive small group of hairs on the frons. Additionally, Klyuchko (1978) noted that the previous four genera, along with Prodotis John [Grammodes] possess spicules inside the aedeagus. Klyuchko found that the female genitalia of some Ophiusa species possess a distinctively large and spiral shaped bulla, a sclerotization on sternite VII (sterigma) that obscures the opening to the ostium, and an absence of spines inside the bursa copulatrix in Anua [Ophiusa], Ophiusa, and Dysgonia Poaphilini. Further studies of these characters are needed to determine if any of these morphological characters can be used to diagnose the Ophiusini or Ophiusini +Poaphilini clade. Hacker (2001) revised Clytie, dividing the genus in to two subgenera (Clytie and Hypoglaucitis Staudinger) based on differences in genitalia morphology. Although Hacker did not discuss related genera in the revisionary part of this work, he grouped the Clytie species between Ophiusa and Dysgonia in his catalogue (Hacker 2001).Published as part of Homziak, Nicholas T., Breinholt, Jesse W. & Kawahara, Akito Y., 2016, A historical review of the classification of Erebinae (Lepidoptera: Erebidae), pp. 516-542 in Zootaxa 4189 (3) on page 533, DOI: 10.11646/zootaxa.4189.3.4, http://zenodo.org/record/16619
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
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
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
