Abstract: community acquired pneumonia is one of the main health problems in children. s. pneumoniae is the most important bacterial microorganism at any age. gram negative bacteria are a rare cause of this entity and when present, they usually are related with several risk factors like immunocompromised host, prolonged hospitalization and antimicrobial therapy, repeated surgical interventions, prolonged use of invasive mechanical ventilation and other medical invasive devices. in this group of bacteria, pseudomonas aeruginosa is the third in order of frequency to cause pneumonia and sepsis in the community setting. it's more widely known as a nosocomial agent. it's very unusual to be community acquired and even rarer in patients without risk factors for infection by this pathogen. in this paper we describe the case of a girl with both community acquired pneumococcal and pseudomonas necrotizing pneumonia and empyema at the same time, without any evidence of a predisposing factor.

Abstract: La sabana de Bogotá está localizada a los 2600 msnm y tiene temperaturas que oscilan entre -5 y 25 oC (promedio: 14oC). Con base en archivos, notas de campo, revisión bibliográfica y la base de datos existente en el Laboratorio de Investigaciones en abejas de la Universidad Nacional de Bogotá (LABUN) se obtuvo información sobre las abejas silvestres presentes en la ciudad de Bogotá y localidades aleda as. Además se hicieron muestreos en diferentes sitios de la ciudad y alrededores, observaciones directamente en campo y se recopiló información sobre plantas visitadas por las abejas en la zona de estudio. Se encontraron 40 especies de abejas pertenecientes a 18 géneros, distribuidas en las cinco familias registradas para el país. Halictidae y Apidae fueron las familias más ricas en especies. El 82,5% de las abejas encontradas son de distribución neotropical y el 25 % de distribución típicamente andina. Se presentan datos sobre comportamiento de forrajeo, arquitectura de nidos y actividad externa para algunas especies de abejas silvestres urbanas. Thygater aethiops y Caenohalictus sp. nidifican principalmente en parques y en las proximidades de parches de plantas ornamentales, en tanto que Anthophora walteri nidifica en áreas secas y con escasa cobertura vegetal. Las abejas del género Bombus se encontraron nidificando fuera de los límites estrictamente urbanos. Las plantas más visitadas fueron principalmente especies ornamentales pertenecientes a las familias Acanthaceae, Asteraceae, Caprifoliaceae, Solanaceae y Scrophulariaceae.

Evolution and the nature of time
Baquero,Fernando;
International Microbiology , 2005,
Abstract: the concept of time is critical in evolutionary thought, but rarely has it been considered as an object of theoretical research by evolutionary biologists. evolution is an organism's possibility of access to the future; in other words, evolutionary reward is paid out as increased time. replicating entities are granted time, but for them, time only serves to allow replication and evolution, and to further expand the frontier of time. the present review discusses the possible influence of considering time not as a pure dimension (or an a priori intuitive condition of human experience) but as an object in itself. at least as a metaphor, time can be considered as a self-replicating entity rooted in physical (including biological) beings, with the result of producing dimensional time. time self-replication forces beings to replicate, which, in turn, further sustains the replication of time. in that sense, time-replication may constitute the driving force, i.e., the basic engine, providing directional energy to the evolutionary process. the philosophical roots, caveats, and perspectives of this hypothesis are presented here. the metaphor of replicating-time plays with the possibility of viewing time not as a merely regulatory component of scientific inquiry but instead, as a real and creative constituent of nature and, for this reason, an object worthy of research in the natural sciences.
Desarrollo psicológico y escolarización en los enfoques socioculturales: nuevos sentidos de un viejo problema
Baquero,Ricardo;
Avances en Psicología Latinoamericana , 2009,
Abstract: this paper introduces some central issues addressing the relationship between educational practices and developmental processes in the context of socio-cultural approaches. it shows the peculiarities of the specific weight of school practices and their impact on development and its differential valuation under what wertsch has called the problem of "genetic hierarchies" in the characterization of development. the question about the increasingly decontextualized use of semiotic tools, considered one of the central vectors in development occurred in school settings, is discussed. finally, we examine some practical implications that these discussions yield for the intervention in the so-called massive "school failure".
Elei??es e capital social: uma análise das elei??es presidenciais no Brasil (2002-2006)
Baquero, Marcello;
Opini?o Pública , 2007, DOI: 10.1590/S0104-62762007000200001
Abstract: this article has as a main objective analyze the influence of electoral process (presidential) in time 1 (2002), in brazil in the constitution or not of social capital in time 2 (2006), both in the institutional dimension, as well as its informal dimension. based upon electoral data collected by eseb (electoral studies in brazil) we postulate the hypothesis that in economic and ethical adverse conditions, formal procedures do not influence the citizens formation of social capital and political empowerment, instead it generates negative predispositions in relation to politics. in these circumstances it prevails untrusty political culture, allowing the prevalence of factors in the electoral process. in this case, in the election and reelection of lula in 2002 and 2006 respectively.
Democracia formal, cultura política informal e capital social no Brasil
Baquero, Marcello;
Opini?o Pública , 2008, DOI: 10.1590/S0104-62762008000200005
Abstract: in this article we analyse the theoretical distortions that emerge when the brazilian democratic construction process is analyzed utilizing exclusively the institutional approach. this approach does not explain the ambiguities between the emergence of a market economy and a passive and distrustful society of their elected officials and political institutions. in that context, adverse political conditions are produced that do not contribute for the democratic strengthening and the institutionalization of a participative political culture. the question to answer is: is it possible to develop political capacity of citizens through social capital as an alternative mechanism of citizenship? the results of the data examined in this paper are not too convincing.
Construindo uma outra sociedade: o capital social na estrutura??o de uma cultura política participativa no Brasil
Baquero, Marcello;
Revista de Sociologia e Política , 2003, DOI: 10.1590/S0104-44782003000200007
Abstract: this article examines the relationship between democracy, political culture and social capital in brazil. the topic is approached comprehensively, based on the belief that the above concepts are in permanent interaction. in the brazilian case, however, it is possible to identify several factors that have historically had a impact on the configuration of a type of political culture, hybrid in nature, that brings together attitudes that are favorable to democracy and negative toward political institutions. it is argued that this problem is neither temporary nor conjunctural; rather, it is structural and poses difficulties for strengthening democracy. within such a scenario the development of social capital would increase citizens' power, in theory and practice, allowing them wider participation in the political arena. data used here are based on quantitative and qualitative research carried out in the state of rio grande do sul, between 1974 and 2000. study results suggest that brazilians are weak on ability to cooperate, which may explain low rates of political participation and consequent democratic instability.
Cultura política participativa e desconsolida??o democrática: reflex?es sobre o Brasil contemporaneo
BAQUERO, MARCELLO;
S?o Paulo em Perspectiva , 2001, DOI: 10.1590/S0102-88392001000400011
Abstract: exame de alguns dos fatores histórico-estruturais, cuja influência tem se mostrado significativa na estrutura??o de padr?es de atitudes e comportamentos de desconfian?a e desencanto da sociedade brasileira em rela??o às suas institui??es políticas e, principalmente, aos políticos. os resultados do estudo indicam que a existência de fatores dessa natureza acabam por descaracterizar a democracia no país e permitem o surgimento de formas antidemocráticas de governar.
