Trilobitofoenus Macedo, n. gen.
No full textTrilobitofoenus Macedo n. gen. (Figs. 5, 6g, 7 g –h, 8 b, 11 i –n, 12 e–g, 13g –i, 14 f, 15) Type species. Trilobitofoenus plaumanni Macedo. Etymology. The name of the genus is derived from Trilobite, because of the mesoscutum sculpture, which in dorsal view, gives to the wasp the appearance of a trilobite (Figs. 12 e–g). The gender is masculine. Description. Body length between 10.0–15.0 mm (exclusive of ovipositor). Head. Subtrapezoidal in dorsal view (Figs. 11 i, 11 k, 11m); mandible in frontal view with apex acute; malar space short, almost disconnected from gena (Figs. 11 j, 11 l, 11 n); clypeus with a longitudinal ridge (Fig. 6g); clypeus and face without longitudinal striae; occipital margin simple (Figs. 11 i, 11 k, 11m). Mesosoma. Pronotum with three lobes well defined (Figs. 13 g-i); pronotal process absent (Figs. 13 g-i); propleuron collar shaped anteriorly (Fig. 8 b); mesonotum rounded in lateral view (Figs. 13 g-i); mesoscutum with anterior portion rather smooth and posterior portion rugose or striate, as long as wide, and forming two different planes separated by depressed notauli, parapsides distinct (Figs. 12 e-g); mesepimeron with a dorsal ridge (Figs. 13 g-i); fore and middle tibiae uniformly colored; hind tibia entirely black to dark brown; metacoxa rather smooth at posterior portion (Fig. 14 f); median propodeal carina flattened, either present at anterior half, or absent; fore wing jugal lobe present; discal cell present (subtriangular) (Fig. 7 g) or absent (Fig. 7 h), vein r–m present (spectral) or absent, fore wing vein 2 –M tubular in 1 st 1 / 3 and spectral in remaining portion (Fig. 5 a); hind wing with 3–5 equidistant hamuli (Fig. 5 a). Metasoma. First metasomal tergum with edges separate, not concealing 1 st sternum; female subgenital sternum with a slitlike Y-shaped notch (as Fig. 10 a); ovipositor longer than T 2 +T 3 and shorter than metasoma (Fig. 5). Distribution. Neotropical: Mexico (Chiapas), Guatemala, Brazil (Amazonas and Santa Catarina). Trilobitofoenus shows a more widespread distribution range than the other two exclusively Neotropical genera, occurring between 15 ºN and 27 ºS (Fig. 15). Species occur in tropical rainforests (southern Mexico, Guatemala, and Amazon) and in an area originally occupied by a subtropical conifer forest in southern Brazil. Biology. Unknown. Comments. There is scarce material of this genus, with each species recorded for only one or two localities.Published as part of Macedo, Antonio Carlos Cruz, 2009, Generic classification for the Gasteruptiinae (Hymenoptera: Gasteruptiidae) based on a cladistic analysis, with the description of two new Neotropical genera and the revalidation of Plutofoenus Kieffer, pp. 1-32 in Zootaxa 2075 on pages 19-20, DOI: 10.5281/zenodo.18721
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

I decided not to group the <i>Spinolafoenus</i> + <i>Trilobitofoenus</i> clade into a unique genus because of the six synapomorphies exclusively shared by the <i>Trilobitofoenus</i> species. The autapomorphies of <i>Spinolafoenus</i> are the crenulate occipital margin, the truncate mesonotum, and the entirely light ovipositor sheath. These autapomorphies are not exclusive of <i>Spinolafoenus</i>. However, the genus has other exclusive characters in Gasteruptiinae that were not used in the cladistic analysis: mesosoma uniformly areolate; metacoxa areolate at posterior portion; and longitudinal axis of propodeum slightly concave. The <i>Spinolafoenus</i> isolation was probably the result of the Andes formation.</p>Published as part of <i>Macedo, Antonio Carlos Cruz, 2009, Generic classification for the Gasteruptiinae (Hymenoptera: Gasteruptiidae) based on a cladistic analysis, with the description of two new Neotropical genera and the revalidation of Plutofoenus Kieffer, pp. 1-32 in Zootaxa 2075</i> on page 16, DOI: <a href="http://zenodo.org/record/187219">10.5281/zenodo.187219</a>
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
