In the 90s of the 20th century, Brazil has undergone significant changes in its development model, with the withdrawal of the state from economic activities. We consider how the discourse on privatization constitutes a relevant place for observation of recent Brazilian history. In this period, the privatization of state companies, among them telecommunications ones are performed. This article analyzes, based on the theoretical and methodological principles of discourse analysis in the tradition opened by Michel Pecheux, as the press feeds the imagination of future in the discourse on privatization of telecommunications companies. To do so, in order to understand the discursive relationships established in dominant commercial media, we devote our analysis to a corpus of reports and articles extracted from newspapers Folha de S. Paulo and O Estado de S. Paulo, which, in general, have taken a position in favor of privatization and changes in the Brazilian development model. The analysis shows that the future benefits are designed for the whole society. Thus, the past is represented negatively, because it would have produced bad effects on society and must therefore be rejected and denied in its historical continuity. In this discursive practice, privatization is introduced as a symbolic milestone period related to modernity and the construction of citizenship prosperity that will fall in the future to be built from this event. Positive meanings are focused in the future, which is directly related to privatization. Thus, the privatist position of the analyzed newspapers try to crystallize the sense of 'privado' as something beneficial and desirable, stabilizing a memory for the discursive event of privatization. This management of historical time, therefore, produces a line of continuity between present and future and a rupture between past and present, whose links are deleted to produce positive meaning for the privatization of the telecommunications.

An unstructured mesh �nite volume discretisation method for simulating di�usion in anisotropic media in two-dimensional space is discussed. This technique is considered as an extension of the fully implicit hybrid control-volume �nite-element method and it retains the local continuity of the ux at the control volume faces. A least squares function recon- struction technique together with a new ux decomposition strategy is used to obtain an accurate ux approximation at the control volume face, ensuring that the overall accuracy of the spatial discretisation maintains second order. This paper highlights that the new technique coincides with the traditional shape function technique when the correction term is neglected and that it signi�cantly increases the accuracy of the previous linear scheme on coarse meshes when applied to media that exhibit very strong to extreme anisotropy ratios. It is concluded that the method can be used on both regular and irregular meshes, and appears independent of the mesh quality.
