Full text linkA identidade de um indivíduo é resultante não apenas de características pessoais inerentes á sua personalidade, mas também pelo meio social que o engloba e o insere em determinadas normas de condutas que irão fazer parte de sua visão de mundo, em nenhum momento da história dos contatos, pacíficos ou não, entre índios e brancos, no Brasil, podemos falar em um pleno apagamento dos traços identitários indígenas. Apesar das tentativas do governo colonial, bem como do imperial e republicano, os saberes culturais indígenas nunca foram completamente sobrepostos pelos modelos europeus, despertando inclusive, em determinados momentos, o interesse ou a aceitação dos colonizadores. Conhecer a identidade do povo indígena Guarani da cidade de Santa Maria/RS, a partir dos pressupostos da clínica psicossocial da identidade, se torna indispensável neste momento único da formação e agregação das primeiras reservas oficiais - aldeias Guaranis do Município de Santa Maria
Aspects of the biology of Cotesia alius (Muesebeck, 1958) (Hymenoptera: Braconidae: Microgastrinae) on Opsiphanes invirae amplificatus Stichel (Lepidoptera: Nymphalidae) in Rio Grande do Sul, Brazil
No full textThe species Cotesia alius (Muesebeck, 1958) (Hymenoptera: Braconidae: Microgastrinae) is a larvae parasitoid of Opsiphanes invirae amplificatus Stichel (1904) (Lepidoptera: Nymphalidae). Hymenopteran parasitoids larvae and pupae are recorded acting as defoliators of palm. Concerning the scientific and economic importance of these interespecific relationship, and aiming to increase the knowledge to natural and conservative biological control, the present study records in the State of Rio Grande do Sul State, Brazil, some data on the biology of this C. alius as larval parasitoid of O. invirae amplificatus Stichel (1904). Based on 35 postures were recorded 4581 cocoons. On 16 postures (48%) observed all cocoons were open and empty, indicating that all parasitoids emerged (Normal). In the 19 remaining postures (52%) (Altered), 134 cocoons (6%) were closed with C. alius intacts in six postures (40%) (Intacts) or remains (fragments) (44%), and in Eulophidae intact within three postures (16%). These data can be used in mass rearing of parasitoids, and biological control of defoliator’s palm
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
