A autora toma como base romances de autores de língua portuguesa - O ano da morte de Ricardo Reis (1984), do português José Saramago, Nove noites (2002), do brasileiro Bernardo Carvalho, e O outro pé da sereia (2006), do moçambicano Mia Couto - para estudar as relações entre literatura e história na produção literária contemporânea. A obra investiga a intertextualidade presente nos romances, ou seja, a relação entre linguagens, uma vez que esses autores construíram as narrativas ficcionais de suas obras recorrendo a elementos de origem histórica, como textos literários, textos históricos, notícias jornalísticas, fotos, cartas e depoimentos atribuídos a figuras históricas. Da intertextualidade resultaria um plano discursivo mais amplo, que extrapola efetivamente o campo dos textos reaproveitados pelos romances. Apoiada em teorias literárias que discutem o modo intertextual, a autora foca sua análise em cada um dos romances. Na obra do escritor português, permeada de releituras de fatos da história de Portugal ocorridos em 1936 e da poesia de Ricardo Reis, heterônomio do poeta Fernando Pessoa, a obra revela os meios pelos quais Saramago coloca em discussão dois mitos lusitanos: Salazar e o próprio Pessoa. Em Nove noites, que remete à passagem do etnólogo norte-americano Buell Quain pelo Brasil e de sua morte na floresta amazônica em 1939, o livro detecta a discussão sobre o mito do bom selvagem que revestiu o índio brasileiro. Já na obra do moçambicano Mia Couto, cuja narrativa é entremeada de fragmentos de escritos históricos de 1560 e de ditados populares, entre outros textos, percebe-se a reflexão sobre a reapresentação da história da exploração do continente africano por colonizadores portugueses e também pelos próprios africanos

OBJECTIVE: To evaluate the accidents with biological material among medical students interning in a trauma emergency room and identify key related situations, attributed causes and prevention. METHODS: we conducted a study with a quantitative approach. Data were collected through a questionnaire applied via internet, with closed, multiple-choice questions regarding accidents with biological material. The sample comprised 100 students. RESULTS: thirty-two had accidents with biological material. Higher-risk activities were local anesthesia (39.47%), suture (18.42%) and needle recapping (15.79%). The main routes of exposure to biological material were the eyes or mucosa, with 34%, and syringe needle puncture, with 45%. After contamination, only 52% reported the accident to the responsible department. CONCLUSION: The main causes of accidents and routes of exposure found may be attributed to several factors, such as lack of training and failure to use personal protective equipment. Educational and preventive actions are extremely important to reduce the incidence of accidents with biological materials and improve the conduct of post-exposure. It is important to understand the main causes attributed and situations related, so as general and effective measures can be applied.

The objective of this study was to define a method for estimating soybean crop area in the Northern Rio Grande do Sul state (Brazil). Overall, six different remote sensing methods were proposed based on spectral-temporal profile and minimum and maximum values of NDVI/MODIS related to the stages of sowing, maximum development and harvesting of soybean areas. The resulting estimates were compared to official crop area data provided by the Brazilian government, using statistical analysis and the fuzzy similarity method. The performance of each method depended on information such as crop size, type of crop management, and sowing/harvesting dates. Regression coefficients of determination and fuzzy agreement values were above 0.8 and 0.45, respectively, for all methods. For operational monitoring of soybean crop area, the empirical threshold applied to the image difference with inclusion of harvest image method was the most effective, producing estimates that matched closely the official data. For spatial analysis the application of multitemporal images classification method is recommended that generated a map of better quality. The efficiency of these methods should be evaluated in the areas of soybean expansion in the state.

This paper is the result of a research project on the subject of youth, violence and school. The purpose of this project was to investigate the understanding of the young people on the violence in society, at school and in their own lives. The assumption is that knowing the aggressors' and victims' perspective about their experiences of violence helps to clarify the symbolic and the normative universes that rule violent conducts and the possible ways to reduce the incidence of violence. Data were collected through focus groups. One of the groups was composed by students qualified by their school's board as protagonists in situations of violence. The other group was consisted by those considered as good students. Data analysis shows the differences between the logic of violence at school, the school violence and violence against the school.
