Based on Hengeveld and Mackenzie (2008)’s Functional Discourse Grammar (FDG), this article aims to analyze the natural and marked orderings of argument constituents in declarative sentences of Brazilian Portuguese taken in IBORUNA corpora. In this way, we conclude that the two natural orderings, proposed by Pezatti (1992), are determined by semantic factor, especially by semantic functions, while the marked ordering ir determined by pragmatic factor, especially by the attribution of pragmatic functions.

This study aims to investigate the Idioms (IEs) or combinations related to the Italian lexical units testa and capo, in comparison to the Portuguese lexical unit cabeça. Since they have come from two completely different etyma, they are not perfect synonyms; on the contrary, they gave rise to several expressions that are common to just one lexical units. Corpus selection was made in monolingual Italian general dictionaries and then the data was classified according to each typology: idioms that are common only with the unit capo; idioms just with head; idioms that are synonyms with both; IEs whose translations refer to other parts of the body. As a result, we found that most of the IEs with capo or testa have common semes, but most of them also are specific to one or other lexical unit exclusively, confirming the difference in semantic features between them as well as non-univocity between languages.

This paper presents methodological considerations related to the study of the plant lexicon of the Juruna ethnic group, an indigenous people of the Xingu Indigenous Park, Mato Grosso State, Brazil. The language of this ethnic group, along with that spoken by the Xipaya, belongs to the Juruna family of the Tupi stock. It is a tonal language with SOV syntactic structure (Fargetti 1992, 2007), and presents interesting processes of reduplication (Fargetti 1997). Part of our broader research project on the lexicology and lexicography of the language, research on the Juruna plant lexicon is still in development, together with studies of other semantic fields such as birds, material culture, and kinship relations. However, it is already possible to see interesting linguistic issues involving word formation, as well as issues of the relationship between language and culture (especially those related to “perspectivism”). These issues are presented in this paper.

High throughput sequencing (HTS) provides new research opportunities for work on non-model organisms, such as differential expression studies between populations exposed to different environmental conditions. However, such transcriptomic studies first require the production of a reference assembly. The choice of sampling procedure, sequencing strategy and assembly workflow is crucial. To develop a reliable reference transcriptome for Triatoma brasiliensis, the major Chagas disease vector in Northeastern Brazil, different de novo assembly protocols were generated using various datasets and software. Both 454 and Illumina sequencing technologies were applied on RNA extracted from antennae and mouthparts from single or pooled individuals. The 454 library yielded 278 Mb. Fifteen Illumina libraries were constructed and yielded nearly 360 million RNA-seq single reads and 46 million RNA-seq paired-end reads for nearly 45 Gb. For the 454 reads, we used three assemblers, Newbler, CAP3 and/or MIRA and for the Illumina reads, the Trinity assembler. Ten assembly workflows were compared using these programs separately or in combination. To compare the assemblies obtained, quantitative and qualitative criteria were used, including contig length, N50, contig number and the percentage of chimeric contigs. Completeness of the assemblies was estimated using the CEGMA pipeline. The best assembly (57,657 contigs, completeness of 80 %, < 1 % chimeric contigs) was a hybrid assembly leading to recommend the use of (1) a single individual with large representation of biological tissues, (2) merging both long reads and short paired-end Illumina reads, (3) several assemblers in order to combine the specific advantages of each.

The main goal of this work is to build a sketch on how language is used in mathematics classrooms. We specifically try to understand how teachers use language in order to share meanings with their students. We initially present our main intentions, summarizing some studies that are close to our purposes. The two theoretical frameworks which support our study – the Model of Semantic Fields and the Wittgensteinian “games of language” – are then presented and discussed about their similarities and distinctions. Our empirical data are some classroom activities recorded and turned into “clips”. Such clips were transcribed and our analysis was based on these transcriptions. Data analysis – developed according to our theoretical framework – allowed us to build the so-called “events” and, then, comment on some understandings on how language can be used in mathematics classrooms.

In this paper we present results of research conducted on the constitution of the identity of CEM (Centre for Mathematics Education), a group of mathematics teacher educators from the city of São Paulo, Brazil (1984-1997). We emphasize the processes of constitution of CEM’s identities, on the perspective of Oral History in Mathematics Education, of the Model of Semantic Fields and of theories of identities. As part of the broader endeavor of examining possibilities for constituting identities for the group, from several theoretical standpoints, here we report an exercise on constituting the identity of CEM from a Cartesian standpoint; the overall assumption is that we are not properly interested in what CEM is or was, but on the possibilities themselves. We argue that such analysis leads to an understanding of the group as being an accident involving the individual identities of its members but not to an understanding of CEM’s group identity as such.

A utilização da Web como plataforma para a educação a distância (e-learning), tem sido uma das grandes alternativas para a educação em sala de aula tradicional. Embora esses sistemas sejam amplamente utilizados, existem limitações quanto à dificuldade de busca, integração e reuso dos materiais existentes. Neste contexto, neste trabalho é apresentada uma arquitetura multiagente para o desenvolvimento de sistemas Web semânticos para a gestão de conteúdos educacionais – SWSGC, onde de acordo com os requisitos do usuário são propostos os conteúdos educacionais (OAs) do curso. Tais conteúdos são recuperados de repositórios heterogêneos de OAs, anotados mediante padrões de metadados educacionais e ontologias de domínio. Esta arquitetura proposta visa automatizar atividades relacionadas à gestão de OAs tais como: a autoria de OAs, a autoria de curso, e a busca e a anotação semântica de OAs.
