NOTA SÔBRE CRIADOUROS NATURAIS DE FLEBÔTOMOS EM DEPENDÊNCIAS PERI-DOMICILIARES, NO ESTADO DE SÃO PAULO
No full textO autor relata o resultado de suas observações sôbre biologia de flebótomos realizadas em uma região endêmica de Leishmaniose Tegumentar Americana do Estado de São Paulo. Tais observações, levadas a efeito em domicílios e suas dependências, resultaram na verificação de criadomos de Phlebotomus intermedius Lutz e Neiva, 1912 em chiqueiros. O autor observou também marcada hematofagia exercida por exemplares dessa espécie em porcos domésticos. Conclui, notando que tal espécie está, na região referida, adotando hábitos domésticos.The author reports the results of observations on biology of sand-flies (Phlebotomus) made in an endemic region of American Leishmaniasis of the State of São Paulo, Brazil. These observations made in houses and its surroundings showed the presence of breeding-places of Phlebotomus intermcdius Lutz e Neiva, 1912 in piggeries. The author has also seen exemplares of that species feeding on domestic pigs, concluding that species is acquiring domestic habits in the refered region
NOVA ESPÉCIE DE CULICÓIDES (DIPTERA, CERATOPOGONIDAE) DE SÃO VICENTE,ESTADO DE SÃO PAULO, BRASIL
No full textNo decurso de pesquisas biológicas que estamos levando a efeito em São Vicente, tivemos oportunidade de deparar com uma nova espécie de Culicoides Latreille, 1809. Tal espécie foi obtida nas coletas realizadas em armadilha tipo Shannon com isca animal. Embora só tenhamos encontrado exemplares fêmeas, o número dos mesmos foi suficientemente alto para permitir uma descrição satisfatória.The author describes Culicoides brasilianum, based on female specimens collected in São Vicente, State of São Paulo, Brazil. This speciesbelongs to the "guttatus group" and it is dose to C. guttatus (Coquillet). The differential characters are mainly: r-m crossvein not infuscated and halter knob brown
NOVA ESPÉCIE DE CULICOIDES (DIPTERA, CERATOPOGONIDAE) DO BRASIL CENTRAL
No full textO autor descreve Culicoides Ruizi, baseado em material procedente de Aruanã, Estado de Goiaz, Brasil. A espécie aproxima-se de C. insigtiis Lutz, 1913, C. foxi Ortiz, 1950 e C. trinidadensis Hoffman, 1925, das quais se diferencia fàcilmente por apresentar três áreas claras na célula R5 da asa, aspecto êsse que lhe é característico.The author describes Culicoides ruizi, based on specimens collected in the locality of Aruanã, State of Goiaz, Brazil. This species is nearly C. insignis Lutz, 1913, C. foxi Ortiz, 1950 and C. trinidadensis Hoffman, 1925. The differential character more evident, is the presence of three pale spots in the R5 cell of the wing
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
