The aim of this article is to broaden our understanding of education and the concept of womanhood in the Brazilian society of the 19th century. On the basis of the analysis of a number of novels typical of the period it is concluded that novels had or intended to have a pedagogical function among the educated elite in the education of women. In this way, literature constituted an expression of a dominant and socially determined conception of womanhood and a pedagogical instrument that imposed social values.

Recently, Bourdieu’s sociological tradition has emerged as an important trend in research in science education. This paper presents some critiques elaborated by Bernard Lahire towards Bourdieu’s sociological approach. The main purpose of our incursion into Lahire’s critique is to argue and introduce the methodology of sociological portraits as an important resource for research in science education. After describing this methodology, it is illustrated with a portrait of dropout on an undergraduate course in chemistry. Diogo’s portrait illustrates, at the empirical level, some basic features of individual dispositions (variability, genesis, transferability, dichotomy and contextuality). From this portrait, it was possible to illustrate how the resonance between students’ and institution’s dispositions helps explain their sense of membership and belonging to the course. Finally, we highlight some potentialities of sociological portraits to the purposes of sociological research in science education.

Glacigenic diamictite successions of the Macaubas Group are widespread in the western domain of the Aracuai orogen, east of the Sao Francisco craton (Brazil). Diamictites also occur on this craton and in the African counterpart of the Aracuai orogen, the West Congo belt. Detrital zircon grains from the matrix of diamictites and sandstones from the Macaubas Group were dated by the U-Pb SHRIMP technique. The geochronological study sets the maximum depositional age of the glacial diamictites at 900 Ma, and indicates multiple sources for the Macaubas basin with ages ranging from 900 to 2800 Ma. Sm-Nd T-DM model ages, determined on whole rock samples, range from 1.8 Ga to 2.5 Ga and get older up-section. Comparison of our data with those from the cratonic area suggest that these glacial deposits can be correlated to the Jequitai and Carrancas diamictites in the Sao Francisco craton, and to the Lower Mixtite Formation of the West Congolian Group, exposed in Africa. The 900-1000 Ma source is most probably represented by the Zadinian-Mayumbian volcanic rocks and related granites from the West Congo belt. However, one of the most voluminous sources, with ages in the 1.1-1.3 Ga interval, has not been detected in the Sao Francisco-Congo craton. Possible sources for these grains could occur elsewhere in Africa, or possibly from within the Brasilia Belt in western central Brazil. (C) 2011 International Association for Gondwana Research.
