Las demandas sanitarias de las familias
Durán,María ángeles;
Gaceta Sanitaria , 2004, DOI: 10.1590/S0213-91112004000700031
Abstract: households are the social units that mediate the relationship between individuals and the health system. households provide the basic conditions for health, as well as the services related directly or indirectly with medical therapies. the range of demands on the health system is widening constantly, and it is forseeable that in the near future the activities of prevention, rehabilitation, reproduction, aesthetics and identity production, as well as with social organization, will become more important than the strictly curative tasks. the role played by new types of families has to be underlined, as well as the role of inmigrant families, a manifestation, at the health level, of the consequences of globalization. the study offers much information published for the first time and ends with a forecast of the changes in the health care demands in europe, due to demo.

Carrasquero-Durán,A;
Anales de la Asociaci?3n Qu?-mica Argentina , 2006,
Abstract: mercury concentration was measured in the hair of people who live and work in centres were rocks and minerals are processed to recover gold by amalgamation with mercury. hair samples were analysed for total mercury (t-hg) by cvaas (cold vapour atomic absorption spectrometry) in males (n= 104) and females (n= 11) aged 2 - 68 years. t-hg ranged between 1.0 and 186.4 μg.g-1. the highest value was found was found in a 34 year woman, the other members of her family had between 5.0 and 83.0 μg.g-1. males had an arithmetic mean of 8.15 μg.g-1 (min = 1.0 μg.g-11. max = 83.95 μg.g-1), which is less than the value found for females of 33.6 ?g.g-1.(min = 1.0 μg.g-1. max = 186.4 μg.g-1). the 27 % of females hair samples exceeded the limit of 10 μg.g-1 that the world health organization consider as the non observed adverse effects levels (noael). for males this proportion was only 4 % with a noael of 50 μg.g-1. there was no statistical difference in t-hg between the first four age groups, but the group > 50 years showed the highest mean (7.5 μg.g-1) differing significantly from other age groups. it was also found that samples of the most consumed carnivorous fishes have hg levels above the value of 0.5 μg.g-1. in general, results showed the presence of hg in individuals with concentrations in hair similar to those reported for other mining areas in south america.

Diversidad florística de los petenes de Campeche
Rafael Durán García
Acta botánica mexicana , 1995,
Abstract: En el presente trabajo se discute brevemente el uso de distintos índices y modelos teóricos en el estudio de la riqueza florística, la diversidad y la distribución de abundancias de las especies en las comunidades vegetales. Se ensaya la aplicación de estas herramientas descriptivas en cuatro comunidades insulares de vegetación selvática (petenes) del noroeste del estado de Campeche. Se plantea el uso de los números propuestos por Hill como mejores indicadores de la diversidad. Los resultados indican que la dominancia disminuye y la diversidad se incrementa conforme aumenta el tama o de los petenes. En cuanto a la distribución de abundancias, los petenes parecen ajustarse al modelo de Motomura, lo que apoyaría la idea de que son comunidades que se encuentran en distintos estadios de un proceso sucesional.

Aprendizaje En Colaboración En Derecho Romano.
María Paula Durán
Revista de Estudios Sociales , 2004,
Abstract: Collaborative learning is a classroom practice consistent with constructivism which, according to findings from various investigations, enables students to learn the contents of the subject they learn, to handle language proper to such a subject, to develop critical thinking ski l ls, and to generate values such as tolerance and the understanding and respect of the ideas of others, through dialogue with peers in the classroom and under teacher's guidance. Through this investigation I found that collaborative learning helped my Roman Law students from Universidad de los Andes to construct rigorous and precise definitions about this subject's legal concepts throughout the semester. Additionally, I found that my students gained understanding of Roman Law concepts and developed skills to use them in analyzing and resolving complex legal cases through group conversations. Finally, I found that thanks to collaborative learning my students developed social attitudes such as appreciation of learning from others' ideas, and values such as tolerance, respect and solidarity, among others.
Sobre el modo de producción de las artes. Marx y el trabajo productivo
José María Durán
Nómadas , 2008,
Abstract: En mi contribución Arte y capital. Releyendo el Capítulo VI (inédito) de El Capital (Nómadas 13, 2006.1) había delineado una relación posible entre producción artística y capital tomando como base las nociones de producción y valor tal y como aparecen en el capítulo VI: Resultados del proceso de producción inmediato en el que Marx parece confinar la producción artística a la esfera del trabajo improductivo al no participar en la producción de plusvalía. Retomo ahora esta aproximación y hago una lectura más atenta del pasaje en el que Marx se refiere a la actividad productiva del escritor John Milton para subrayar la diferencia entre trabajo productivo e improductivo que también caracteriza el modo de producción artístico. En la coda final paso a examinar brevemente alguno de estos aspectos en la obra de Adolfo Sánchez Vázquez.
