Percursos do silêncio: as narrativas de Luiz Vilela
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2015.O objetivo a que me propus nesta tese foi demonstrar formas de silêncio nas narrativas de Luiz Vilela. Nesse sentido, o silêncio foi para minha leitura a matéria propulsora de sentidos e reveladora de subjetividades dos personagens nas narrativas. Desenvolvi leituras do silêncio com base nas próprias histórias contadas, nos excessos e negações que o mundo contemporâneo impõe aos indivíduos e nos fracassos amorosos, alicerçadas em pressupostos de Mikhail Bakhtin e em teorias acerca da modernidade. Ao relacionar o silêncio e o tempo histórico percorri os caminhos da memória, destacando o silêncio político e as políticas de silenciamento até chegar às narrativas que problematizam a velhice e as mazelas que dela decorrem.Abstract : The goal that I proposed in this thesis was to demonstrate the silence forms, on Luiz Vilela?s narratives. In this way, silence was my one driving reading matter of senses and revealing subjectivity of your characters in this narratives. I developed silence readings based in own silence stories, in excesses and denials that the contemporary imposes to individuals and failures in loving, grounded in Mikhail Bakhtin's assumptions and theories about modernity. By linking the silence and history time I scoured the paths of memory, highlighting the political silence and silencing policies to get to narratives that question the old age and the ills that flow from it

O sistema de numeração: seus princípios na história movem seu aprendizado na infância.
No full textTrabalho de Conclusão do Curso de Especialização em Educação Infantil - Segunda Edição – Polo Florianópolis, para a obtenção do Grau de Especialista em Educação Infantil.Este trabalho consiste numa reflexão sobre a importância do acesso das crianças pequenas ao conhecimento matemático. O foco desta pesquisa está no último ano da Educação Infantil e busca desenvolver o pensamento matemático infantil e analisar como as crianças elaboram seus processos de quantificação, em situações de interação com os objetos e com os outros, estando num estágio de pré-cálculo, ao se depararem com a História dos números e com os suportes que o homem utilizou para se comunicar, contar e se organizar. O objetivo maior está em propiciar um encontro destas crianças com a história, ao demonstrar como se deu o processo de elaboração do sistema de numeração, ao longo do tempo, para que assim possam compreender seu próprio processo de elaboração do pensamento matemático. Neste trabalho uma metodologia é proposta e esta tem como intuito proporcionar situações e atividades que tragam a história passada, através de imagens e relatos e possibilite diversas vivências do processo de contagem vivido pelo homem (desde o primitivo até os dias atuais) e dos suportes utilizados para identificar e registrar quantidades, para que a criança compreenda o nosso sistema de numeração. A elaboração desta metodologia procura fundamentar-se no Enfoque Histórico Cultural do desenvolvimento elaborado por L. S. Vygotsky e seus continuadores
MeSH term explosion and author rank improve expert recommendations
No full textInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
Heteragrion roquei Vilela, Rodrigues & Lencioni 2022, sp. nov.
No full textHeteragrion roquei Vilela, Rodrigues & Lencioni sp. nov. (Figs. 1 a−b, 2, 3a−b, 4a−b, 5d) Holotype. ♂ (CZYG3085 BA), Brazil, Bahia state, Municipality of Una, Fazenda Araruna, (-15.3146, -39.1621), 40 m, 19.ix.2019, M.E. Rodrigues leg., UESC. Paratype. 1♂ (CZYG3065 BA), same data as holotype, except (-15.3101, -39.1621), FAAL. Etymology. Named roquei (noun in genitive case) after Dr. Fábio de Oliveira Roque, professor and researcher at the Federal University of Mato Grosso do Sul, Brazil, for his dedication and contribution to science with studies focused on ecology and conservation of continental aquatic ecosystems, especially with the aquatic insects. And also, for the friendship, partnership in research and orientation to studies with Odonata during the second author’s master’s and doctorate. Head (Figs. 1 a−b, 3a). Labium and labrum brown; base of mandibles and genae pale colored, apex of mandibles dark brown; remainder of the head orange, except for the brown vertex, and following black areas: a black stripe lateral to each antenna, a black stripe ranging from each postocular area to the occipital bar. Rear of the head pale colored, darker on the occipital region. Thorax (Figs. 1 a−b, 3a−b). Prothorax mostly orange; anterior lobe black laterally and posteriorly, remainder orange; medial lobe mostly orange with two black stripes on each side; hind lobe orange with a black medial spot. Pterothorax mostly orange/yellow, with a black middorsal carina; mesepisternum orange with a black basal stripe; mesopleural suture pale; mesepimeron and metepisternum each orange with a medial thin black stripe; remainder of pterothorax yellow. Coxae and trochanter pale colored; legs pale with smoky femoral areas, darker on distal femora and apical tibiae. Wings (Fig. 2). Hyaline, reaching S6; venation and Pt dark brown; Pt overlying 2.5 cells in Fw, 2 cells in Hw, oblique proximally; 2 Pq cells in all wings; 19 Px in FW, 15 Px in HW. Abdomen (Fig. 1a). S1 mostly yellow, with a brown dorsal spot; S2 pale laterally, gradually becoming brown dorsally, with a yellow dorsal stripe; S3−6 mostly black with pale basal rings and pale spots on their 4/5; S7 black, becoming dark brown posteriorly; S8−9 dark brown; S10 black, becoming dark brown ventrally. Anal appendages (Figs. 4 a−b). Dark brown with darker coloration on the carinas and spines; BP subequal to MP; ventrobasal expansion (VbE) present, ‘C’ shaped in posterior view; dorsobasal expansion (DbE) broad, as large as VbE; MP roughly quadrangular, plate like, squared apex; sclerotized ridge of MP oblique, slightly curved, bearing at least six denticles, reaching MP posterior margin; AP the shortest, ending blunt tip curved inwards. Paraprocts greatly reduced. Measurements. FW: 27.3; HW: 26.5; AL: 41.7; TL: 50.1. Variations in paratypes. Male paratype do not vary in cerci morphology. Only slight thoracic coloration differences were spotted, probably related to aging. Male paratype varied in size as follows: FW: 27−27.3, HW: 25.9−26.5, AL: 40−41.7, Total: 48−50.1. Female. Unknown. Differential diagnosis. Heteragrion roquei belongs to Lencioni’s Group A, composed of males lacking developed paraprocts (Lencioni 2013). Based mainly on cercus morphology, and some coloration characters, the morphologically closest taxa of the new species are H. triangulare Hagen in Selys (Figs. 3 c−d, 4c−d), 1862, and H. gracile Machado, 2006 (Figs. 1c, 3 e−f, 4e−f). Despite the resemblances, the new species can be separated from these congeners by the following character combination (see Table 1, and respective figures; other species in parentheses): ventrobasal expansion (VbE) present, ‘C’ shaped in posterior view (absent in H. triangulare, Fig. 4c, who has an apophysis; larger in H. gracile, Fig. 4e); dorsobasal expansion (DbE) broad, as large as VbE (narrow in H. gracile, Fig. 4e); single MP ridge (two ridges in H. gracile, Fig. 4e); ridge reaching MP apex (not reaching apex in H. triangulare and H. gracile). The new species can readily be separated from H. triangulare because this species presents an apophysis on the base of the cercus (Fig. 4c, VbA), instead of an excavated VbE. The remainder combination of characters should be sufficient to separate H. roquei from H. gracile. Habitat and ecology. At the type locality (Figures 5−6), Heteragrion roquei sp. nov. inhabits lotic environments placed within gallery forests with plenty of shaded areas, where they can be spotted on leaves exposed to the sunlight. Such habitats are common places to find Heteragrion species (Ávila-Jr. et al. 2017, 2020; Vilela et al. 2021a; Mendoza-Penagos et al. 2022), and in that same locality H. consors Hagen in Selys, 1862 was a sympatric species.Published as part of Vilela, Diogo Silva, Rodrigues, Marciel Elio & Lencioni, Frederico A.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
