Em busca do tempo partido: a consciência histórica e o MST

The work that follows is dedicated to the study of the historic time experience by the political militancy from our time. The political militant from the left-wing is the one that denies the state of current things, recovering a historic experience located far before its time and projecting a future beyond the incessant reproduction of the present relations. We chosen the Landless Workers Movement, not as study object, but as specific place where this consciousness is made and can be comprehended. The historic consciousness study of the landless militancy is, for us, the best starting point to understand the magnification of the historical time operated on the change of social relations lived inside an organization. The time division between before and after, as well as the history being understood as a progress isn t a natural given data, but a construction that obeys the contradictions of the present. It, therefore, must understand how the present lived by the militancy operates changes on the consciousness of time. From documents, reference books, formation notebooks and several materials produced by MST, we try to understand the way that the movement tells his history and lists with this wider experience of the struggle for the change of the current social order. Similarly, when we hear reports of history of several militants, we try to comprehend how this wider narrative re-orients the sight over history himself, over the experience of contradictions on before and after making the landless militant

O Partido Comunista (1922-1962): lugar de memória, espaço de disputa

This work studies the dispute by Party Communist s memory in Brazil during and after division which it resulted in the appearance of two parties entitled communists, in the brazilian political context, in the final of the fifties and beginning of the sixties: the Brazilian Communist Party (in Portuguese, Partido Comunista Brasileiro) and the Communist Party of Brazil (in portuguese, Partido Comunista do Brasil). Along of yours three chapters, the author tries to answer some questions as: what were the elements which constituted the Communist Party s memory, in the period from 1922 to 1956? At which moment did this memory pass to be fiercely contested? Who and which documents reveal this? How did it happen the dispute by this memory? The approach to topic consider which the production of memory by Communist Party and the dispute for your possession by communists of PCB and of PCdoB happened in scope of national reality and of party, spaces notions understand from concept of memory developed for authors as Halbwachs, Le Goff, Pollack and Pierre Nora. To explain the objectives of historical research it has used as methodology the exam and the interpretation of documentary and bibliographical sources, with priority for the party s documents then it was depicted a collective interpretation about the events considered more importants. The sites of Partido Comunista do Brasil (www.pcdob.org.br or vermelho.org.br) and of Partido Popular Socialista (www.pps.org.br) also went consulted

Temporal and spatial variability in the macrozoobenthic community along a salinity gradient in the Castillos Lagoon (Uruguay)

The macrozoobenthic community of the Castillos Lagoon system (East Coast of Uruguay) was sampled during autumn, winter, spring and summer of 1991, in order to describe the community structure and the spatial and temporal patterns of distribution. Eleven sampling stations were distributed along a salinity gradient in a north-south direction (8 replicates were collected at each station). The maximum density of organisms was found at the central part of the lagoon (stations 6 and 7) where the bivalve Erodona mactroides and gastropod Heleobia australis were dominants. No significant correlation between the overall abundance of organisms and salinity could be demonstrated (r = 0.43, p > 0.1). However, a reduction in organism abundance between the autumn and the summer coincided with a marked drop in salinity. Falling levels of dissolved oxygen could have influenced the decreasing density of organisms (r = 0.75, p < 0.05). Species richness and diversity were correlated (p < 0.1) with salinity but the degree of correlation was not uniformly significant between sampling periods.

Occurrence of freshwater stingrays (Chondrichthyes: Potamotrygonidae) in the Uruguay River and its tributaries, Uruguay, South America.

Four records of potamotrygonids in the Uruguay River and its tributaries in Paysandu, Uruguay are reported in this paper. The first one was a specimen caught in 1934, of undetermined sex and weighing 120 kg and with a disc width of ca 150 cm. The second specimen, caught in 1998, was also of undetermined sex; it weighed 50 kg total weight and its disc width measured 103 cm. The third specimen was caught in 2001; it was an adult male, weighed 114 kg total weight and its disc width measured ca 110 cm. The fourth one, caught in 2004, was a female, 11 kg in total weight and with a disc width of 80 cm. According to the size and general description, specimens were identified as Potamotrygon brachyura, to date the only potamotrygonid confirmed for Uruguay.

Petrological and geochemical evolution of the alkaline Valle Chico Massif, southeastern Uruguay

The Valle Chico Massif is a member of the Early Cretaceous alkaline magmatic suite of rocks distributed around the Parana Basin. Three magmatic associations are recognized: (1) the Plutonic Association, characterized by syenites, quartz syenites, and syenogranites; (2) the Volcanic Association, mainly composed of porphyritic quartz trachytes; and (3) the Porphyritic Dike Association consisting of rhyolites and trachytes. Judging by their geochemical behavior, the rhyolites exhibit a weak peralkaline affinity, and are genetically connected by progressive melting processes, whereas the other lithologies have a metaluminous nature, and are products of mineral fractionation. An enriched mantle of Transamazonian age, geochemically similar to OIB, is postulated as a possible source.

Paraná Basin: Mineral resource potentials in Brazil, Uruguay, and Paraguay

The Paraná Basin is a Western Gondwanan cratonic basin that is better defined as the Paraná depositional site, since it has a diverse history as a basin. Sedimentation started in the Ordovician-Silurian, followed by extensive marine Devonian deposition. A Late Paleozoic/ Triassic facies cycle wedge was clearly built during Pangean time. The Early Cretaceous was characterized by extensive basaltic lava flows immediately before the break-up of Pangea. Following these rifting and drifting processes, the basin's structural framework was totally rebuilt, generating new depositional sites in the Late Cretaceous to Tertiary. Based on more recent data, at least two different basins may be defined during the evolution of what was once considered a unique basin. Nevertheless, even if considered as a single basin, the sedimentary pile of the Paraná Basin has considerable economic potential, until now exploited only rudimentarily, except for its groundwater resources. Aggregates, limestones, clays, industrial sands, gems, dimension stones, hydrocarbons, coal, peat, and uranium are some of the potential mineral resources of this basin. Copyright © 1997 by V. H.

Assessing relationships between genetic evaluations using robust regression with an application to holsteins in Uruguay

Globalization of dairy cattle breeding has created a need for international sire proofs. Some early methods for converting proofs from one population to another are based on simple linear regression. An alternative robust regression method based on the t-distribution is presented, and maximum likelihood and Bayesian techniques for analysis are described, including the situation in which some proofs are missing. Procedures were used to investigate the relationship between Holstein sire proofs obtained by two Uruguayan genetic evaluation programs. The results suggest that conversion equations developed from data including only sires having proofs in both populations can lead to distorted results, relative to estimates obtained using techniques for incomplete data. There was evidence of non-normality of regression residuals, which constitutes an additional source of bias. A robust estimator may not solve all problems, but can provide simple conversion equations that are less sensitive to outlying proofs and to departures from assumptions.
