Bloodiella andalusica Nowicki 1935
No full textBloodiella andalusica Nowicki, 1935 In a previous paper (Viggiani & Filella 2019), the eggs of M. dentipes were hypothesized to be the host of B. andalusica. The observations carried out in 2020 demonstrate that B. andalusica is a solitary egg endoparasitoid of M. dentipes. In May 2020 adults emerged from overwintering egg clusters of the chrysomelid host, they oviposited in fresh host eggs and a new adult emergence occurred in June, when 90 specimens of B. andalusica were reared. The trichogrammatid shows the same phenology of the eulophid A. macrolenei described above.Published as part of Viggiani, Gennaro, Filella, Francesco & Bernardo, Umberto, 2021, The egg endoparasitoids of Macrolenes dentipes (Olivier) (Coleoptera: Chrysomelidae), with description of a new species of Aprostocetus Westwood and notes on its host (Hymenoptera: Eulophidae), pp. 57-64 in Fragmenta entomologica 53 (1) on page 61, DOI: 10.13133/2284-4880/483, http://zenodo.org/record/814798
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
Macrolenes dentipes
No full textNotes on Macrolenes dentipes The genus Macrolenes Chevrolat, 1836, includes the species Macrolenes dentipes (Olivier, 1808) and Macrolenes bellieri (Reiche, 1860); the latter recorded only in Sicily. M. dentipes is widely distributed in the Mediterranean region (Regalin & Medvedev 2010) and rather easily recognized for the male front legs having long and dentate femora (Fig. 14). The adults are observed on several plants [Pistacia, Rhus (Anacardiaceae), Quercus (Fagaceae), Fraxinus (Oleaceae), Paliurus and Ziziphus (Rhamnaceae)] from May to August, but they are preferably active leaf-eater on Pistacia lentiscus L. (Agoiz-Bustamante et al. 2019). Adults of M. dentipes are phytophagous, while larval stages are phyto-zoo-saprophagous (Schöller 1998). The females oviposit eggs in clusters attached to the leaf surface by long strands. The first instar larva is undescribed. Larval development occurs on the soil. The third larva, described by Medvedev & Schöller (2002) on specimens collected under a stone covering an ant’s nest under a Quercus ilex tree, is protected by a simple case, light grey to brownish, with the fine line-like structure on the surface. M. dentipes is one of the ant-nest beetles (Agrain et al. 2015), but according to Schöller & Witte (2007), the larvae of the most advanced genera of Clytrinae (Labidostomis and Macrolenes) have lost secondarily the ability to penetrate into the ant nests and remain at the entrance of the host’s nest, namely, a species of Tapinoma: a new, protected and food-rich niche of a dolichoderine. In our study area a massive population of M. dentipes was recorded in May 2019. Adults were observed on several plants (Arbutus firstly unedo, Olea europaea, Pistacia lentiscus, Vitis vinifera), but they produced severe damages mostly on lentisk (Figs 12-13). Mating (Fig. 14) and egg clusters (Fig. 15) were observed mostly on olive tree leaves. Eggs (Fig. 16) are subcylindrical, basally pointed and distally trunked, 0.7-0.9 mm in length and 0.4 mm in width. The diameter of the egg distal end is about as that of the head of the first emerging larva of the leaf beetle (0.3 mm). The chorion of the egg is coated with brown material. The number of eggs/cluster varied from 4 to 38 (average: 18; SD ± 10.6, n = 23). The eggs hatched at the beginning of June (Fig. 17); after hatching, they showed the distal cap completely detached (Fig. 11). The first instar larva (Fig. 18), 0.8-0.9 mm in length, is typically J-shaped, with the last abdominal segments directed ventrally. The head chaetotaxy (Fig. 19) offers diagnostic characters for the identification of the species; in particular: the single seta, on each side of the epicranial suture, not simple but at least slightly spiny as the other dorsal epicranial setae, except the very long 3 rd seta; all frontal setae moderately or densely spiny, with the 3 rd pair not longer than the second one.In the key for the identification of the clytrine genera by Wasowska (2007), based on the first instar larva, the larva of M. dentipes runs near Lobidostomis, having one seta on each side of epicranial suture, on top of the head, but simple in the latter species, not spiny.Published as part of Viggiani, Gennaro, Filella, Francesco & Bernardo, Umberto, 2021, The egg endoparasitoids of Macrolenes dentipes (Olivier) (Coleoptera: Chrysomelidae), with description of a new species of Aprostocetus Westwood and notes on its host (Hymenoptera: Eulophidae), pp. 57-64 in Fragmenta entomologica 53 (1) on page 61, DOI: 10.13133/2284-4880/483, http://zenodo.org/record/814798
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
