El lugar de las masculinidades en la decisión del aborto.

En este artículo analizamos el papel que los varones desempeñan en la decisión de interrumpir un embarazo. Para ello, damos cuenta de las distintas formas de participación masculina en tal decisión, a partir de los relatos de hombres y mujeres colombianos entrevistados en el marco de la investigación HEXCA en la ciudad de Bogotá. En nuestro análisis tomamos en consideración el influjo que tienen en la decisión de un aborto las diferencias de género, clase, generación y de momentos de curso de vida. Consideramos que esta experiencia, así como la forma de asumirla y significarla, representa un dilema ético para las personas. Esta disyuntiva se debe entender dentro de un sistema de referencia patriarcal que impide que las decisiones sobre la reproducción y el aborto sean tomadas en forma soberana por la mujer que se embaraza. Y que permite, por el contrario, que otros agentes sociales tengan el poder de intervenir, legislar, regular y decidir sobre estas cuestiones.

Horizontal profiles of longwave and shortwave radiation components over sea ice near Barrow, Alaska during the 2011 melt

An integrated instrument package for measuring and understanding the surface radiation budget of sea ice is presented, along with results from its first deployment. The setup simultaneously measures broadband fluxes of upwelling and downwelling terrestrial and solar radiation (four components separately), spectral fluxes of incident and reflected solar radiation, and supporting data such as air temperature and humidity, surface temperature, and location (GPS), in addition to photographing the sky and observed surface during each measurement. The instruments are mounted on a small sled, allowing measurements of the radiation budget to be made at many locations in the study area to see the effect of small-scale surface processes on the large-scale radiation budget. Such observations have many applications, from calibration and validation of remote sensing products to improving our understanding of surface processes that affect atmosphere-snow-ice interactions and drive feedbacks, ultimately leading to the potential to improve climate modelling of ice-covered regions of the ocean. The photographs, spectral data, and other observations allow for improved analysis of the broadband data. An example of this is shown by using the observations made during a partly cloudy day, which show erratic variations due to passing clouds, and creating a careful estimate of what the radiation budget along the observed line would have been under uniform sky conditions, clear or overcast. Other data from the setup's first deployment, in June 2011 on fast ice near Point Barrow, Alaska, are also shown; these illustrate the rapid changes of the radiation budget during a cold period that led to refreezing and new snow well into the melt season.
