As possibilidades de uso de ferramentas da informática: software para análise de dados qualitativos e ISD

The objective of the present article is to identify and discuss the possibilities of using qualitative data analysis software in the framework of procedures proposed by SDI (socio-discursive interactionism), emphasizing free distribuited software or free versions of commercial software. A literature review of software for qualitative data analysis in the area of social sciences and humanities, focusing on language studies is presented. Some tools, such as: Wef-tQDA, MLCT, Yoshikoder and Tropes are examined with their respective features and functions. The software called Tropes is examined in more detail because of its particular relation with language and semantic analysis, as well as its embeded classification of linguistic elements such as, types of verbs, adjectives, modalizations, etc. Although trying to completely automate an SDI based analysis is not feasible, the programs appear to be powerful helpers in analyzing specific questions. Still, it seems important to be familiar with software options and use different applications in order to obtain a more diversified vision of the data. It is up to the researcher to be critical of the analysis provided by the machine.

Clinical features and genetic analysis of four Brazilian kindreds with resistance to thyroid hormone

Objective Resistance to thyroid hormone (RTH) is a dominantly inherited syndrome of reduced tissue responsiveness to thyroid hormone usually due to mutations located in the ligand-binding domain and adjacent hinge region of the thyroid hormone receptor beta (TR beta). In the present report we describe the clinical and laboratory characteristics and the genetic analysis of patients with this rare disorder from a Brazilian population.Patients Four unrelated Brazilian families with diagnosis of RTH were studied. Age at diagnosis varied from 14 months to 29 years.Results All affected individuals were clinically euthyroid, except for one patient who presented immediately after birth with hyperthyroidism. All individuals had tachycardia and goitre, elevated concentrations of free thyroid hormones and reduced sensitivity to thyroid hormone. Direct sequencing analysis of the TR beta gene revealed four previously reported mutations: c.949G -> A, c.1313G -> A, c.1357C -> A and c.1358dupC in families A, B, C and D, respectively.Conclusion the present report shows that the frequent mutations described in the thyroid hormone receptor worldwide are also present in the Brazilian population, which is characterized by a variable ethnic background.

Produção e qualidade de raiz tuberosa de cultivares de batata-doce no Oeste do Paraná

The objective of this work was to evaluate sweet potato cultivars with starch processing capability, on two cultivation periods, in the western region of Parana (Brazil). Sweet potato was grown at Marechal Candido Rondon, Parana State (24 degrees 33'40 '' S and 54 degrees 4'12 '' W), at a mean annual temperature between 14 and 28 degrees C. The experiment was designed in complete randomized blocks, in a factorial scheme of 4 cultivars (CNPH 003, CNPH 004, Brazlandia Roxa, and Brazlandia Rosada) and 2 cultivation periods (115 and 183 days), with four repetitions. The evaluated parameters were the root productivities (t ha(-1)) and the physical and chemical root composition (humidity, pH, acidity, starch, total soluble sugars and fibers). Data was submitted to all analysis of variance (Anova) and the means were compared by the Tukey test at 5% of probability, Results indicated that sweet potato yield at the cultivars was higher during the 183 day cultivation period (average of 9.14 t ha(-1)) than during the 115 day cultivation period (average of 4.25 t ha(-1)). Thus the CNPH 003 cultivar seems to be a better indication for starch extraction, due to the lowest fiber content in the root, the driest mass content and the largest yield of starch per area.

A formação de trabalhadores brasileiros: a experiência do Colégio Isabel

Colegio Isabel was a project that aimed to "civilize" the indigenous children who lived in the Vale do Araguaia region, Goias Province, to educate national workers and, progressively, incorporate the lands owned by the Indians in the productive process. Colegio Isabel allowed its students a marginal integration in the society, assigning them functions that the so called "civilized" people considered degrading. The egress students lived an ambiguous and marginal life, regarding the original ethnic groups and the adopted society.

A compilação de corpora comparáveis na área de negócios e sua relevância para a tradução e terminologia

This article aims at highlighting the importance of Corpus Linguistics particularly to the compiling of specialized comparable corpora to the field of Translation as well as to the practice of translation itself. Hence, we report the stages of the compilation and the organization of bilingual comparable corpora in the Business field and its applications, with the purpose of also highlighting its relevance to two of our target audiences: translators and also researchers in the Terminolgy/Terminography field.

Flutuação populacional de cigarrinhas-das-pastagens na Região Oeste do Paraná

The spittlebugs are considered the most important pests in tropical pastures. The damages caused by these insects decrease the production of pastures. The objective this work was to study the population dynamics of Notozulia entreriana, from June 2007 to June 2008, and the correlation with meteorological and environmental factors (rainfall, temperature, daily solar radiation and pasture height). Therefore, sampled were made in three areas of grassland in the municipality of Marechal Candido Rondon-PR. Sampling of adults and nymphs was made. Also we determined which species of spittlebugs (Hemiptera: Cercopidae) occur in the western region of Parana State. The population fluctuation of N. entreriana showed four peaks during the period of favorable development - spring / summer. The daily solar radiation had a higher correlation with the population. Rainfall, temperature and pasture height had little correlation with the population dynamics. The species that occurred with greater abundance was N. entreriana, representing 88.4% of the total insects collected in western of Parana State.

O processamento automático de línguas naturais enquanto engenharia do conhecimento linguístico

In this paper, we provide a brief description of the multidisciplinary domain of research called Natural Language Processing (NLP), which aims at enabling the computer to deal with natural languages. In accordance with this description, NLP is conceived as "human language engineering or technology". Therefore, NLP requires consistent description of linguistic facts on every linguistic level: morphological, syntactic, semantic, and even the level of pragmatics and discourse. In addition to the linguistically-motivated conception of NLP, we emphasize the origin of such research field, the place occupied by NLP inside a multidisciplinary scenario, their objectives and challenges. Finally, we provide some remarks on the automatic processing of Brazilian Portuguese language.
