Limites e contribuições do uso da EME para pesquisas de cunho qualitativo na aquisição do PB

The main objective of this paper is to answer the following question: how can we draw a parallel, during the analysis of the data, between children who are at different moments in the language acquisition process or who belong to different populations (children that are monolingual, bilingual, with language disorders, etc.)? In order to answer this question, we are discussing the advantages and limitations of adopting a measure like MLU, from English Mean Length of Utterance, or EME as it was named in Brazil, proposed by Roger Brown (1973). We intend to verify the effective contribution of these measures to the studies in the area and propose an adaptation in the studies that use a qualitative approach. Firstly, we recall the study of the criteria proposed by Brown (1973), Scliar-Cabral (1976), Parker & Brorson (2005), Parisse & Le Normand (2006), and Araújo (2007), and by scholars of Brazilian Portuguese morphology, like Câmara Jr (2009), Monteiro (2002), and Kehdi (1990), among others. Secondly, from a dialogic-discursive point of view (BAKHTIN, 2006; BAKHTIN/ VOLOSHINOV, 1992, 1981), we provide as an example the research on the plural in the language acquisition process (HILÁRIO, 2010, 2011b, 2012). The reflections made indicate that EME may be a useful measure for the researches on language acquisition. Nevertheless, adaptations should be done and its inherent problems should be taken into account, especially if other factors are considered – like the age, the number of types/occurrences, the maximum limit of items per utterance etc. – although it is not the only parameter of analysis. Considering that EME may vary according to the conditions of production and may not reflect the qualitative changes in the children’s discourse, other factors should be analyzed, like the context of the discourse, the participants involved etc.

Divergência genética entre cinco genótipos de melão rendilhado

Estimou-se a divergência genética entre cinco genótipos de melão rendilhado (Cucumis melo var. reticulatus Naud.) (JAB-20, JAB-21, JAB-22, JAB-23 e 'Bônus nº 2') e determinou-se qual a contribuição relativa das 16 características avaliadas [nº médio de flores masculinas, hermafroditas/planta; produção total de frutos/m², peso médio dos frutos comerciáveis; diâmetro médio transversal e longitudinal do fruto (DMTF e DMLF); diâmetro médio transversal da inserção do pedúculo (DMTP); espessura média do mesocarpo e epicarpo (EMM e EME); diâmetro médio longitudinal e transversal do lóculo (DMTL e DMLL); proporção da cavidade (PC); desprendimento de sementes (DS); teor de sólidos solúveis totais (SST), pH e acidez titulável (AT)] na divergência genética. Obtiveram-se dois grupos de similaridade: I- JAB-20, JAB-21 e 'Bônus nº2' e II- JAB-22 e JAB-23. As características DMLF, DMTP, DMLL, DS e SST foram as que mais contribuíram para a divergência genética entre os genótipos.

Selección del tratamiento farmacológico en el estado de mal epiléptico en niños

The status epilepticus (SE) is characterized by a series of crises which occur without recovery of consciousness or a single seizure lasting more than 30 minutes and can damage the central nervous system and systemic. The duration and frequency of attacks are directly related to patient prognosis. Whether seizures occur often and are longer, increase the risk of neurological and systemic complications. Child population has a higher frequency of seizures and it is associated with a lower threshold of immature brain to trigger these episodes. Aim: To determine the safest drugs prescribed for children in SE, their doses and schedules. A bibliographic survey was performed in electronic databases. Methods: The scientific health descriptors used for search was: “status epilecticus” and “anticonvulsivants” and “child”. Results: This strategy identified 396 manuscripts, of whom four were considered eligible for the study, after the assessment by floating reading and criteria. Of these, two were randomized trials and two descriptive. The studies address the use of oral midazolam, rectal diazepam and intravenous lorazepam. Conclusions: All investigated drugs were effective in treat in status epilepticus. Lorazepam is highlight, since it has fewer secondary effects and, as an alternative to the intravenous, oral midazolam. However, there is a need for further studies to demonstrate the efficacy and safety in the use of drugs in children.
