El artículo revisa los relatos de Francisco de Amigorena y de Alexander Gillespie, un funcionario y un militar, escritos a fines del siglo XVIII e inicios del XIX, que han sido la base de la historiografía tradicional argentina sobre el mundo rural de Buenos Aires. Desde la perspectiva de la nueva historiografía económica argentina y de la historia del paisaje, replantea la imagen de la conformación de las clases dominantes rurales de la época y el papel económico del interior de la pampa de la provincia de Buenos Aires. Específicamente, el artículo cuestiona la idea de un espacio desierto, tal como la pintó la historiografía romántica, y propone el perfil de un hinterland heterogéneo, dedicado a distintas actividades.

Results of the study of Argiudolls in two localities (Zarate and Veronica) of the Pampean plain, Argentina, are presented in this contribution. This is a typical area covered by loess. The magnetic studies carried out allowed to determine the presence of detrital magnetite and titanomagnetite, as well as maghemite, pedogenic goethite and superparamagnetic particles (SP). In Veronica soils, a depletion of ferromagnetic minerals is recorded The dominant process in these soils has been the reductive loss of detrital magnetite and titanomagnetite. This is associated with a greater degree of evolution of the soil, which is determined by the concentration and type of detected clays. The higher clay concentration in these soils facilitated reducing conditions and a greater loss of detrital magnetic particles. The loss is reinforced under poor drainage conditions. In the poorly drained soil of Zarate, a concentration of magnetic particles is observed in the Bt horizon, which is associated with an illuviation process. The well drained soil of the same locality shows neoformation of SP particles. These particles would have an ephemeral life until a new wet period in the annual cycle occurs. Although some characteristics of the magnetic signal appear reinforced by the conditions of drainage, this aspect does not seem to be too significant, at least in the Pampean region with low topographic gradients.

Este projeto pretende verificar a funcionalidade das "Cidades Mundiais" dentro do contexto de uma economia globalizada. Adicionalmente, procura-se estudar se São Paulo e Buenos Aires tendem a ocupar o "posto" de "Cidade Mundial". Dada a evidência de integração comercial e considerando que esta integração se dá, em grande parte, com a Argentina, cabe verificar como se dará a integração entre as duas grandes metrópoles desses dois países em termos concorrenciais e de complementaridade.
