Three new species of mealybug (Hemiptera, Coccomorpha, Pseudococcidae) on persimmon fruit trees (Diospyros kaki) in southern Brazil
No full textBrazil has the greatest insect diversity in the world; however, little is known about its scale insect species (Hemiptera: Coccomorpha). Mealybugs (Pseudococcidae) have been found in at least 50% of persimmon orchards Diospyros kaki L. in the southern part of the country. In this study three new mealybug species on persimmon trees located in the Serra Gaucha Region, RS, Brazil, namely, Anisococcus granarae Pacheco da Silva & Kaydan, sp. n., Ferrisia kaki Kaydan & Pacheco da Silva, sp. n. and Pseudococcus rosangelae Pacheco da Silva & Kaydan, sp. n. are described. In addition, an identification key for the genera occurring on fruit orchards and vineyards in Brazil is provided, together with illustrations and molecular data for the new species
O pensamento gramatical de Manuel Pacheco da Silva Júnior
No full textManuel Pacheco da Silva Júnior, a Brazilian grammarian of 19th century, performed an
important role in the linguistic studies panorama of the time. Like Julio Ribeiro, Maximino
Maciel e Ernesto Carneiro Pereira, he lived the first moments of the scientific period of
Brazilian grammar, when historical comparativism was being implanted here. The purpose
of this work is to analyze the language studies accomplished by Pacheco Silva Júnior in
order to scribe a synthesis of the descriptive model he applied to phonetics, morphology,
syntax, semantics and etymology. The selected works are Grammatica Historica da
Lingua Portugueza (1878), Phonologia (1877), Noções de Semantica (1903), Grammatica
da Lingua Portugueza (1903) this one as co-author with Lameira Andrade. The present
study is part of the research line Linguistic Description of the Post-Graduation Program of
the Arts Institute of the Federal Fluminense University, and it follows the principles of
Linguistics Historiography, specially the ones defended by Konrad Koerner, Pierre
Swiggers and Sylvain Auroux. It is intended, thus, to contribute to the historiography of
the linguistic science practiced in the 19th century, which was an important period for this
area, though still barely explored.Manuel Pacheco da Silva Júnior, gramático brasileiro do século XIX, desempenhou
importante papel no panorama dos estudos lingüísticos daquele período. Como Julio
Ribeiro, Maximino Maciel e Ernesto Carneiro Pereira, viveu os primeiros momentos do
período científico da gramática brasileira, quando aqui se implantava o comparativismo
histórico. Este trabalho tem como objetivo analisar os estudos da linguagem feitos por
Pacheco da Silva Júnior para traçar uma síntese do modelo descritivo praticado por ele em
relação à fonética, morfologia, sintaxe, semântica e etimologia. As obras selecionadas são
a Grammatica Historica da Lingua Portugueza ( 1878 ), Phonologia ( 1877 ), Noções de
Semantica ( 1903 ), Grammatica da Lingua Portugueza ( 1907 ) esta em co-autoria com
Lameira de Andrade. O presente estudo filia-se à linha de pesquisa Descrição Lingüística
do Programa de Pós-Graduação do Instituto de Letras da Universidade Federal Fluminense
e segue os princípios da Historiografia da Lingüística, em especial os defendidos por
Konrad Koerner, Pierre Swiggers e Sylvain Auroux. Pretende-se, assim, que seja uma
contribuição à historiografia da ciência lingüística praticada no século XIX, período
importante para essa área mas ainda pouco explorado

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
