Reusability of dictionaries in the compilation of NLP lexicons

This paper discusses particular linguistic challenges in the task of reusing published dictionaries, conceived as structured sources of lexical information, in the compilation process of a machine-tractable thesaurus-like lexical database for Brazilian Portuguese. After delimiting the scope of the polysemous term thesaurus, the paper focuses on the improvement of the resulting object by a small team, in a form compatible with and inspired by WordNet guidelines, comments on the dictionary entries, addresses selected problems found in the process of extracting the relevant lexical information form the selected dictionaries, and provides some strategies to overcome them.

Spatial distribution of trachoma cases in the City of Bauru, State of São Paulo, Brazil, detected in 2006: defining key areas for improvement of health resources

Introduction: The objective of this study was to analyze the spatial behavior of the occurrence of trachoma cases detected in the City of Bauru, State of São Paulo, Brazil, in 2006 in order to use the information collected to set priority areas for optimization of health resources. Methods: the trachoma cases identified in 2006 were georeferenced. The data evaluated were: schools where the trachoma cases studied, data from the 2000 Census, census tract, type of housing, water supply conditions, distribution of income and levels of education of household heads. In the Google Earth® software and TerraView® were made descriptive spatial analysis and estimates of the Kernel. Each area was studied by interpolation of the density surfaces exposing events to facilitate to recognize the clusters. Results: of the 66 cases detected, only one (1.5%) was not a resident of the city's outskirts. A positive association was detected of trachoma cases and the percentage of heads of household with income below three minimum wages and schooling under eight years of education. Conclusions: The recognition of the spatial distribution of trachoma cases coincided with the areas of greatest social inequality in Bauru City. The micro-areas identified are those that should be prioritized in the rationalization of health resources. There is the possibility of using the trachoma cases detected as an indicator of performance of micro priority health programs.

Spatial and temporal distribution of fishing resources exploited by the Manaus fishing fleet, Amazonas, Brazil

Recursos pesqueiros são importantes fontes de renda e alimento para as populações rurais e urbanas na Amazônia. O presente trabalho avalia a pesca e as variáveis ambientais que determinam a produção de pescarias que desembarcam em Manaus, e avalia também a abundância relativa de recursos pesqueiros em diferentes subsistemas na Amazônia Central. A informação coletada no porto de desembarque de pescado de Manaus foi utilizada para testar um novo índice de captura obtido a partir de um modelo de covariância que apresentou as seguintes variáveis significativas: número de pescadores/dia (dias de pesca vezes número de pescadores por viagem); distância do pesqueiro até Manaus; quantidade de gelo que usou durante a viagem; e nível de rio. Não houve nenhuma diferença significativa entre valores médios de captura entre os subsistemas do Purus, Madeira e de Juruá. Estes resultados sugerem que os tributários da margem direita são similares e mais produtivos em termos comerciais. Concluiu-se que a produção corrente varia de acordo com a magnitude de esforço pesqueiro, por variações ambientais, assim como por aspectos operacionais da pesca, particularmente o consumo de gelo.

Children's labour as a risky pathways to resilience: children's growth in contexts of poor resources

Nesse artigo, analisamos a questão do trabalho infantil como um fenômeno complexo, englobando fatores de risco por um lado e possíveis resultados positivos por outro. Baseados na teoria da resiliência e a partir de uma revisão de literatura, centrada em pesquisas que analisam a própria experiência de crianças sobre o trabalho desenvolvido, mostramos que quando inseridos em ecologias socialmente e fisicamente pobres em recursos, crianças associam sua experiência de trabalho como um caminho para assegurar recursos próprios para superação de adversidades. A compreensão de aspectos subjetivos da experiência de crianças trabalhadores nos permite considerar o trabalho como uma construção culturalmente embasada. Apesar da exploração de crianças não se configurar como o melhor para elas, há evidências de que elas usam quaisquer oportunidades disponíveis, incluindo o trabalho, para navegar em busca de recursos que necessitam e negociam por uma identidade associada à resiliência. Implicações para políticas públicas e intervenções também são discutidas.

Pausas na interpretação teatral: delimitação de constituintes prosódicos

We intend to observe the function of a linguistic resource – the pause – in theatrical interpretation. Connected to the field of speech therapy, we search for theoretical support in the Linguistics field, mainly in prosodic phonology – specifically, we highlight intonational phrase and phonological utterance, prosodic constituents –, proposing a dialogue between these fields, regarding the work with actors. In speech therapy literature, the work with actors focuses, centrally, in organic issues involved in the vocal process, such as “misuse” or “voice abuse”. To a smaller extent, we find, in this literature, researches that emphasize issues regarding interpretation and expressive resources, besides a few emphasizing the importance of linguistic resources in interpretation. Differently, in linguistics literature, the pause is approached, to a larger extent, from the phonetic perspective, related to several language levels. In this research, we analyzed audio recordings of four actors from a same theatrical group, acting the theatrical text Brutas flores, focused on these aims: (1) detect the place where pauses happen in the interpretation of a single text by four actors; (2) survey physical characteristics of length of these pauses; (3) check to what extent the length of a pause is related to the place where it happens, regarding the prosodic limits of intonational phrases (I) and phonological utterance (U). We could observe that, although the interpretation is characterized by the subjectivity of the actor, the interpretation is constructed based in the possibilities offered by the prosodic organization of the text itself, being more or less flexible.We were also able to confirm, by considering the length of VVs units containing pauses, the prosodic hierarchy proposed by Nespor & Vogel, once the length of these units in U's limits was significantly higher than the length in I's limits. Thus, our results reinforce the premise that a linguistic structure overlaps the subjectivity of the actor, i. e., the premise that the strength of linguistic structure organization acts on the possible individual operation/style.

Resources Taken to the Nest by Protopolybia exigua (Hymenoptera, Vespidae) in Different Phases of the Colony Cycle, in a Region of the Medio Sao Francisco River, Bahia, Brazil

The present study aimed to identify what resources were taken to the nest by workers of Protopolybia exigua (de Saussure), to verify if there is a relationship between physical factors of weather and phases of colony development and the collection of different resources and also to observe if the wasps carry macerated prey in the crop. The species collected nectar (62.8%), wood pulp for nest building (6.1%), water(2.9%), prey (0.8%) and resin (0.2%). Moreover, workers of P exigua do carry macerated prey in the crop. There was a positive correlation (r = 0.85, p = 0.0004) between the presence of larvae in the nest and the carrying of solid contents in the crop, which provides strong evidence that this species macerates its prey while still in the field, before taking it to the nest. There was positive influence of the temperature on the collection of nectar (r = 0.89, p = 0.0001) and water (r = 0.46, p = 0.0066) and negative influence of relative air humidity on the collection of the same resources (r = - 0.88, p = 0.0001 and r = - 0.37, p = 0.0160, respectively). Luminosity influenced the gathering of water (r = 0.43, p = 0.0089) and Pulp for nest building (r = 0.31, p = 0.0274) and the wind speed did nor influence the collection of any resources. Nectar is the main item taken to the nest during all phases of the colony.
