A contribuição de um dicionário histórico: o dicionário histórico do Português do Brasil

This article presents the theoretical and methodological road used to construct the Historical Dictionary of Brazilian Portuguese in the XVI, XVII and XVIII centuries (sponsored by CNPq). Starting with some examples and models of historical and diachronic dictionaries we set the model that structures the Dictionary; it has the purpose of assembling in a single book the Portuguese language lexicon responsible for the construction of the Portuguese language in Brazil. Our reference basis is a data bank with many sorts of sources existing along the three centuries of the Brazilian colonial history. This data bank provides the nomenclature of the historical dictionary and allows the construction of the lexicographical definition through its lexical context that is followed by consecrated examples. This article also presents the contributions of the dictionary to future studies of the Brazilian Portuguese.

A coleta de corpus de aprendizes: questões qualitativas em uma pesquisa sobre a escrita de aprendizes de língua espanhola

In this paper we discuss and present the first results gathered from the compilation of a learner corpus comprised of texts written by university students (Language, Literature and Translation Course). We made use of Corpus Linguistics and observations of researchers from the learner’s corpus field, in order to compile and analyze a corpus of argumentative and descriptive texts written in Spanish. Four hundred compositions were collected (about 120 thousand words) from August 2011 to December 2012. The methodology adopted assisted us considerably in maintaining a comprehensive working agenda, taking into consideration students’ needs and using the data collected as subsidy to improve classroom management of content. We also present the difficulties faced during the data gathering and propose procedures do avoid or minimize them.

Plantas entre los juruna: en busca de una metodología para el estudio del léxico

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.

CONTEXT TREE SELECTION AND LINGUISTIC RHYTHM RETRIEVAL FROM WRITTEN TEXTS

The starting point of this article is the question "How to retrieve fingerprints of rhythm in written texts?" We address this problem in the case of Brazilian and European Portuguese. These two dialects of Modern Portuguese share the same lexicon and most of the sentences they produce are superficially identical. Yet they are conjectured, on linguistic grounds, to implement different rhythms. We show that this linguistic question can be formulated as a problem of model selection in the class of variable length Markov chains. To carry on this approach, we compare texts from European and Brazilian Portuguese. These texts are previously encoded according to some basic rhythmic features of the sentences which can be automatically retrieved. This is an entirely new approach from the linguistic point of view. Our statistical contribution is the introduction of the smallest maximizer criterion which is a constant free procedure for model selection. As a by-product, this provides a solution for the problem of optimal choice of the penalty constant when using the BIC to select a variable length Markov chain. Besides proving the consistency of the smallest maximizer criterion when the sample size diverges, we also make a simulation study comparing our approach with both the standard BIC selection and the Peres-Shields order estimation. Applied to the linguistic sample constituted for our case study, the smallest maximizer criterion assigns different context-tree models to the two dialects of Portuguese. The features of the selected models are compatible with current conjectures discussed in the linguistic literature.

Breast imaging: is the sonographic descriptor of orientation valid for magnetic resonance imaging?

Purpose: To evaluate if the Breast Imaging Reporting and Data System (BI-RADS) ultrasound descriptor of orientation can be used in magnetic resonance imaging (MRI). Materials and Methods: We conducted a retrospective study to evaluate breast mass lesions identified by MRI from 2008 to 2010 who had ultrasound (US) and histopathologic confirmation. Lesions were measured in the craniocaudal (CC), anteroposterior (AP), and transverse (T) axes and classified as having a nonparallel orientation, longest axis perpendicular to Cooper's ligaments, or in a parallel orientation when the longest axis is parallel to Cooper's ligaments. The MR image data were correlated with the US orientation according to BI-RADS and histopathological diagnosis. Results: We evaluated 71 lesions in 64 patients. On MRI, 27 lesions (38.0%) were nonparallel (8 benign and 19 malignant), and 44 lesions (62.0%) were parallel (33 benign and 11 malignant). There was significant agreement between the lesion orientation on US and MRI (kappa value = 0.901). The positive predictive values (PPV) for parallel orientation malignancy on MR and US imaging were 70.4% and 73.1%, respectively. Conclusion: A descriptor of orientation for breast lesions can be used on MRI with PPV for malignant lesions similar to US. J. Magn. Reson. Imaging 2012; 36:13831388. (C) 2012 Wiley Periodicals, Inc.
