A new species of Lepidaploa (Asteraceae: Vernonieae) from Minas Gerais State, Brazil
Get PDFLepidaploa scintillans is described as a new species from the Minas Gerais State in southeastern Brazil. This new species can be easily distinguished from other Lepidaploa species by the sericeous, nacreous-argent indumentum of both leaf surfaces and by the subpaleaceous outer pappus, which are unusual features in this genus.Fil: Marques, Danilo.

Heliantheae s.l. (Asteraceae) do Parque Estadual do Biribiri, Diamantina, Estado de Minas Gerais, Brasil
Get PDF(Heliantheae s.l. (Asteraceae) do Parque Estadual do Biribiri, Diamantina, Estado de Minas Gerais, Brasil). Heliantheae s.l., a terceira maior tribo da família Asteraceae, possui 48 gêneros e 379 espécies no Brasil, das quais 199 espécies são restritas ao país. A tribo está bem representada na Cadeia do Espinhaço que apresenta grande diversidade e endemismo. Neste trabalho foi realizado o tratamento florístico de Heliantheae s.l. para o Parque Estadual do Biribiri (PEB), localizado na Cadeia do Espinhaço, município de Diamantina, Estado de Minas Gerais. No tratamento é apresentada uma chave de identificação para as espécies, seguida de descrições morfológicas, comentários taxonômicos e distribuição geográfica. A tribo Heliantheae s.l. no PEB possui nove gêneros e 16 espécies: Acanthospermum, Aldama, Cosmos, Dimerostemma, Galinsoga e Melampodium (uma espécie cada), Aspilia e Bidens (três spp. cada) e Calea (quatro spp.). O PEB apresenta grande representatividade de Heliantheae s.l. quando comparado com outras áreas já estudadas no Estado de Minas Gerais. Além disso, 12,5% das suas espécies são restritas ao Estado, demonstrando a importância do Parque na conservação da flora da Cadeia do Espinhaço no Estado de Minas Gerais.Fil: Marques, Danilo.

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
