Abstract: assessing the impacts of technologies generated by agricultural research is an important issue for inifap. initially, this assessment was referred almost exclusively to economic impacts, but in recent times social and environmental dimensions have been incorporated, as a result of concerns about the sustainability of production systems. in 2009, we conducted a series of surveys to the cooperating producers who participated in a technology transfer project for peach, where primary information was gathered on the economic, social and environmental impact on model gardens, promoted for 6 years in a technology transfer project. in addition, a specialized software was used to estimate the economic benefit to society of investment in the project, assuming the adoption of the technology in an area of 5 hectares, and expecting an average yield of 12 tons per hectare. the estimation of the economic return of the research was carried out by calculating the indicators of convenience; in this case tir was estimated at 63.69%, a van of $ 23.5 million pesos and a benefit /cost ratio of 7.02, which means that for every peso invested in the generation and dissemination of this practice, the country made a $7 profit.

Abstract: La evaluación de los impactos derivados de las tecnologías generadas por la investigación agropecuaria es un tema importante para el INIFAP. Inicialmente, esta evaluación estaba referida casi en forma exclusiva a los impactos económicos; sin embargo, en estos últimos tiempos se han incorporado las dimensiones social y ambiental, en consecuencia de la preocupación por la sostenibilidad de los sistemas de producción. En 2009, se aplicó una serie de encuestas a los productores cooperantes, participantes de un proyecto de transferencia tecnológica en durazno, donde se recabó información primaria sobre el impacto económico, social y ambiental en huertos modelo promovido a través de 6 a os en un proyecto de transferencia tecnológica. Por otro lado, se utilizó un software especializado para estimar el beneficio económico a la sociedad de la inversión realizada en el proyecto, asumiendo la adopción de la tecnología en una superficie de 5 mil hectáreas y esperando un rendimiento promedio de 12 toneladas por hectárea. La estimación del retorno económico de la investigación se realizó a través del cálculo de indicadores de conveniencia, en este caso se estimó una TIR de 63.69%, un VAN de $23.5 millones de pesos y una relación beneficio/costo de 7.02, esto significa que por cada peso invertido en la generación y difusión de esta práctica, el país obtuvo $7 en beneficio económico.

Abstract: the scope of this paper was to identify the role of gender for women as workers, through the perception and discourse of health service providers at the 'health centers for indigenous women' ("casas de salud de las mujeres indígenas") in ometepec, guerrero and matías romero, oaxaca, mexico. it is a qualitative study, based on a secondary analysis of the interviews conducted as part of the "rescatando la experiencia de la casa de la mujer indígena: sistematización y evaluación del proceso" project. a strong sense of the value of work and a strong commitment towards the community were identified. guilt appears as the result of tension between work outside the home and the responsibilities as mothers and wives. the possibility of helping other women is a source of gratification that dissipates these conflicts; prestige and recognition are added to the benefits of their role. the labor experience of female workers in the "casas de salud de las mujeres indígenas" of matías romero, oaxaca and ometepec, guerrero, described in this paper, reveals that it has very specific characteristics, which are difficult to replicate in other regions of the country. in future studies it is necessary to consider the different contexts of vulnerability.

Abstract: Objetivo: establecer la frecuencia de estreptococo beta hemolítico del grupo A (Streptococcus pyogenes) en ni os, mediante una prueba rápida de inmunoensayo cromatográfico.Métodos: estudio piloto de tipo transversal en una muestra no probabilística de 144 ni os entre 3 y 13 a os, asistentes a centros infantiles de Medellín y su área metropolitana y a una institución educativa de Bogotá. Se tomaron muestras de garganta por frotis para la prueba rápida de S. pyogenes y se recolectó información demográfica y de antecedentes personales mediante una encuesta. Se calcularon los promedios con sus desviaciones estándar y los porcentajes de acuerdo con la naturaleza de las variables de interés.Resultados: la edad promedio del grupo fue 5,5 ± 2,8 a os con distribución similar por sexo. Veintiún ni os (14,6%) fueron positivos para S. pyogenes, diez de ellos fueron posibles infecciones y 11, portadores asintomáticos. De los 144 ni os, 45 (31,3%) tenían síntomas faríngeos, de los cuales 10 (22,2%) tenían S. pyogenes. Un total de 99 (68,8%) ni os fueron asintomáticos y 11 de estos (11,1%) presentaron prueba positiva para S. pyogenes.Discusión: la alta frecuencia de S. pyogenes en este grupo es un llamado de atención sobre la necesidad de implementar protocolos de manejo con pruebas rápidas para la detección del microorganismo.

Investigaciones geográficas , 2007,
Abstract: during the two centuries of existance, the knowledge of the direction and trajectories followed by regional geography has been part of the centre of geography as a hole. nowadays, there are not a unique vision of regional thinking but a great variety of theories as perspectives of analysis. the positivist perspective and the models of territorial organizations coexist with the humanist perspectives and those derived of marxism: the poststructuralists and the neomarxists visions. the aim of this paper is to present those theoretical perspectives, concluding with the main contemporary debates we face of the regional thinking.
La geografía regional: tradiciones y perspectivas contemporáneas

Investigaciones geográficas , 2007,
Abstract: El conocimiento sobre las trayectorias y direcciones que ha seguido la geografía regional en sus más de dos siglos de existencia, reviste importancia en momentos en donde el pensamiento regional carece de una visión única y alterna con una gran variedad de formas de analizarlo. La visión positivista y de los modelos de organización territorial se presentan en la actualidad con las posturas humanistas y las derivadas del marxismo, tanto del estructuralista como del llamado neomarxismo. El ensayo hace un recorrido por el desarrollo de estas miradas teóricas, para concluir con una visión de dónde están ahora los principales debates en el pensamiento geográfico regional en la actualidad
Del funcionalismo industrial al de servicios: la nueva utopía de la metrópoli postindustrial del valle de México?

Abstract: El objetivo de este ensayo es responder algunas preguntas que han sido parte de viejas y nuevas reflexiones sobre la Metrópoli del Valle de México, y descubrir las nuevas tendencias que percibimos en su desarrollo. Partimos de suponer que hay confusión en la forma como se le nombra y que la visión de futuro sobre su transformación en el mediano y largo plazo pasa por un cambio importante de la función industrializadora que el modelo de sustitución de importaciones impuso a la ciudad, por otro de servicios y patrimonialista que le impone la visión postindustrial en que se ve inmersa en la actualidad. En esta transformación resalta la importancia de la periferia, dada la ubicación privilegiada que tiene en cuanto al patrimonio natural y cultural que le es propio, posibilitando así su contribución para alcanzar la sustentabilidad de la metrópoli Old and new reflections regarding Mexico Valley’s Metropolis are questioned, in order to discover new trends in urban development of the city.
