En este artículo se focaliza uno de los procesos más generalizados y polémicos que se registran en las grandes ciudades contemporáneas: el desarrollo de conjuntos residenciales que cuentan con seguridad y que sirven de vivienda permanente a los sectores medios y altos de la población. Más concretamente, intentamos cuestionar y examinar –desde una perspectiva etnográfica– las visiones sobre estos conjuntos ancladas en torno a la categoría de fragmentación urbana, a partir del análisis de un ejemplo específico: la emergencia de grandes emprendimientos en la Región Área Metropolitana de Buenos Aires; en este caso se trata de una singular ciudad privada y periférica. AbstractThis article focuses on one of the most generalized, polemic processes recorded in major contemporary cities: the development of residential complexes with security that serve as permanent housing for the middle and upper classes of the population. More specifically, the author attempts to use an ethnographic perspective to question the views on these complexes placed within the category of urban fragmentation on the basis of the analysis of a specific example; the emergence of major developments in the Metropolitan Area of Buenos Aires; in this case, an unusual private, peripheral city.

En este trabajo se investiga la producción social de los asentamientos y barrios populares ubicados en el Área Metropolitana de Buenos Aires. Describe los procesos de integración, la urbanización y la consolidación de los distritos e investiga las trayectorias familiares y estrategias de acceso a la tierra y a la vivienda. Busca también las conexiones entre dos escalas geográficas de análisis: por un lado, los cambios en el barrio y en el lote y, por otro, los cambios en la vivienda. El estudio se realizó en cuatro distritos de la región metropolitana. La investigación de los procesos de producción de hábitat se basó en una encuesta realizada en 2008, y la selección de casos de estudio en profundidad se hizo de acuerdo con los criterios de significación adoptados. Palabras clave: producción del hábitat; estrategias; acceso al suelo urbano; hábitat popular; políticas de regularización. Abstract: This paper investigates the social production of settlements and poor neighborhoods in the Metropolitan Area of Buenos Aires. The processes of urbanization, integration and consolidation of the districts are described and family trajectories and strategies to access land and housing are investigated. The analysis looks for the connections between two geographical scales: on one hand, the changes in the neighborhood and in the lot, and on the other, the changes in housing. The study was conducted in four districts of the metropolitan region. The investigation of the processes of habitat production was based on a survey conducted in 2008, and the selection of cases for study in depth was made according to criteria of significance. Keywords: production of habitat; strategies; access to urban land; popular habitat; regularization policies.

Abstract Background: Two types of EBV (EBV1 and 2) have been shown to infect humans. This study aimed to detect the types of EBV that cause infectious mononucleosis and correlate these viral types with biochemical parameters (AST, ALT and GGT) in the metropolitan region of Belém from 2005 to 2016. Methods: A total of 76 cases of infectious mononucleosis were processed at the Instituto Evandro Chagas, Ananindeua, Brazil. PCR was used to analyze the EBNA3C region for the recognition of EBV types. Biochemical testing (AST, ALT and GGT) was performed by the COBAS INTEGRA clinical biochemistry PLUS 400 / ROCHE automatic analyzer. The data were evaluated using the Statistical Package for Social Science - SPSS 17.0 and GraphPadPrism 7.0 for Windows (GraphPad software, San Diego, CA, USA). Results: EBV1 infection was observed in 71.1% (54/76) of individuals, among whom those > 14 years constituted 66.7% (36/54); the average age was 23 years, and the number of women infected was higher (61.1% [33/54]) than that of men 38.9%[21/54]). The symptoms/clinical signs observed in infection by EBV1 were cervical lymphadenopathy in 64.8% (35/54), fever in 63% (34/54), headache and arthralgia in 20.3% (11/54), and exanthema in 18.5% (10/54). Infection by EBV2 was observed in only 17.1% (13/76) of cases. Coinfection by EBV1 and EBV2, most frequently showing symptoms of fever and cervical lymphadenopathy, occurred in 66.7% (6/9) and 55.6% (5/9) of individuals. Conclusion: EBV1 was predominant in 71% of clinical cases of infectious mononucleosis. The correlation of biochemical parameters in infection by EBV1, EBV2, and coinfection by EBV1/2 revealed a statistically significant difference in mean changes of EBV1 in individuals older than 14 years.

The analysis of some systems of green areas and public parks of the metropolitan area of Guadalajara, other cities of our country Mexico and Latin America, shows common problems such as the deficit of urban green spaces, insecurity, unemployment, and uncertainty with a social exclusion in these areas of stress. Likewise, the lack of economic value of the services provided by such natural systems as recreation is added. Together they are important factors in the allocation of territories destined to this use with respect to others that generate Urban speculation. Therefore, it is proposed to develop a typology of green areas appropriate to the needs of the metropolitan region. It will facilitate the production of inventories that estimate indicators of territorial cohesion, governance, economic profitability, social, environmental quality and innovation, as well as incorporating new technologies that improve geographic information systems and internet media that support management.
