In this paper we compare the resource flows of Chile, Ecuador, Mexico and Peru between 1980 and 2000. In this time span, the domestic extraction of materials increased in the four countries, mainly due to the mining sector in Chile and Peru, biomass and oil in Ecuador and construction minerals in Mexico. Imports and exports increased too, due to the increasing integration in the international markets, prompted by the liberalization policies undertaken by the four countries between the late 1970s and the late 1990s. The four countries had a negative physical trade balance for most of the period analyzed, meaning that their exports exceeded their imports in terms of weight. However, the increase of imports reduced the physical deficit in Chile, Mexico and Peru. Ecuador’s physical deficit was the highest and did not decrease in the period analyzed. Also, a diversification of exports away from bulk commodities could be observed in Chile and Mexico, and to a lesser extent in Peru, whereas in Ecuador the export sector remained mainly based on oil and biomass. More research is needed to explore the environmental effects of this phenomenon. Also, the indirect flows associated to the direct physical flows deserve to be subject to further analysis.

Laboratory surveillance of influenza has shown a low virus activity in Rio de Janeiro during 1980 and 1981. A few influenza A (H3N2) viruses were isolated in both years during the winter months. Serological investigations showed that this subtype has circulated mostly among children under 10 years of age. No H1N1 virus was isolated but an increase in the proportion of adults with antibody to his virus was noted in sera collected in 1981. Influenza B virus was isolated from children in the spring of 1981 and again an increase was noted in the proportion of adults with antibody to this virus.

De 13.196 coproculturas realizadas durante o triênio 1978-1980 em Recife, Pernambuco, foram isoladas 1.720 salmonelas, das quais 1.387 foram caracterizadas sorologicamente. O estudo global possibilitou o reconhecimento de 63 sorotipos concentrados em primeiro plano no grupo sorológico B (73,18%) e identificando-se como tipos mais incidentes: S. typhimurium, S. saint-paul, S. poona, S. derby, S. agona, S. newport, S. oranienburg, S. infantis, S. tshiongwe e S. ndolo, que representaram 1.231 amostras ou 88,75% do total de isolamentos. Algumas considerações de ordem epidemiológica e bacteriológica são discutidas em relação aos quatros sorotipos mais freqüentes.

This paper explores the social profile of the regional elite that has emerged in Spain since the federalization of the State. For the first time, researchers present data about crucial variables like gender, place of birth, age, education, and profession. They make interregional comparisons, and try to explain some unexpected findings like the behavior of political elites in some regions like Catalonia. The authors compare also the social profile of MPs of the two largest parties.

Este trabajo se propone analizar las estrategias electorales y de coalición del PP y del PSOE en las distintas Comunidades Autónomas con el objetivo de demostrar que un mismo partido puede adoptar simultáneamente respuestas. Este comportamiento según el planteamiento que aquí se sostiene se debe que cada comunidad presenta una dinámica de la competencia diferenciada, sobre todo aquellas que cuentan con partidos de ámbito no estatal relevantes.
