Problemas de acción colectiva en procesos de pacificación: oportunismo e instituciones
Zamudio González, Laura;
Perfiles latinoamericanos , 2011,
Abstract: this article introduces what might be considered as a different approach to discus pacifications of countries affected by intra-state conflicts. using the case of the process of pacification in el salvador (1992-1994), i introduce several categories stemming from the new institutionalism in order to understand the role of institutions designed to tackle opportunism. the argument is that asymmetries of information and high transactions costs are particularly acute in postwar periods. this situation creates the ideal conditions and incentives for political actors to act opportunistically, which might derive in severe negative affectations of the peace agreements already in place. this is when the introduction of "rules of the game" designed specifically to tackle opportunism become critical for the success of a pacifications effort.
Presencia de la estética suprematista en Océano Mar de Alessandro Baricco
Laura González
Trans : Revue de Littérature Générale et Comparée , 2007,
Abstract: L’article propose un parallèle analytique entre l’esthétique suprématiste -représentée sous forme paradigmatique par le tableau de Malevitch “Carré blanc sur fond blanc”- et le roman Océan mer de l’italien Alessandro Baricco. Ce livre tire toute sa force de la fa on dont l’auteur italien se sert des principes esthétiques du peintre russe pour mieux les subvertir. Cela est particulièrement évident dans le personnage qui aspire à peindre la mer et obtient un résultat tout à fait inattendu. El artículo propone un paralelo analítico entre la estética suprematista -encarnada de forma paradigmática en el cuadro “Cuadrado blanco sobre cuadrado blanco” de Malevich- y la novela Océano mar del italiano Alessandro Baricco. La fuerza del libro radica precisamente en cómo el autor italiano se sirve de los principios estéticos del pintor ruso para subvertirlos. Ello es especialmente visible en el personaje que aspira a pintar el mar y obtiene un resultado del todo inesperado.

Abstract: Faecal samples were obtained from 300 Mexican children diagnosed as positive for diarrhoea, aged > 2 to < 12 years old, and from 80 children matched for age but with no symptoms of the disease (control group). Two multiplex PCR were used to detect Escherichia coli, Salmonella spp., and Shigella spp. In addition, the two protozoan parasites Entamoeba histolytica/Entamoeba dispar and Giardia intestinalis were detected by conventional methods.All diarrhoeal samples were positive for one or more enteropathogens. The most common enteropathogens in diarrhoeal samples were E. histolytica/E. dispar (70.3%), Salmonella (ohio 28.3%; typhimurium 16.3%; infantis 8%; anatum 0.6%; Newport 0.3%), G. intestinalis (33%), E. coli (ETEC 13.3%; EPEC 9.3%; VTEC 8.6%; EIEC 1%) and Shigella spp. (flexneri 1.6%, sonnei 1%). Infections by two (24%) three (16%) and four (12%) pathogens were observed.This study revealed that 52% of the patients were infected by more than one enteropathogen, notably E. histolitica/E. dispar and Salmonella ohio. These results are useful for clinicians to improve the empiric treatment used in such cases.Diarrhoeal diseases constitute a major public health problem, particularly in the developing world, where the rate of mortality and morbidity is very high [1]. The World Health Organization (WHO) has estimated that 1.5 billion episodes of diarrhoea occur every year in developing countries, resulting in 3 million deaths [2]. In Mexico, a governmental study conducted in the year 2003 reported 4556 cases caused by intestinal infectious [3]. The etiological agents of diarrhoea described in epidemiological studies are transmitted as waterborne and foodborne.Some foodborne pathogens have been recently considered as emerging diseases [4], despite the fact they have been known since a long time ago. For example, outbreaks of salmonellosis have been described for many decades, and yet their incidence have increased over the last 25 years. Diarrhoeal infections can be caus
