"Unirse y Afirmarse" : una red en torno a la revista Nosotros (1907-1917)

En 1907 Alfredo Bianchi y Roberto Giusti fundaron en Buenos Aires la revista Nosotros. Creada en un contexto histórico atravesado por profundas transformaciones y tensiones, la revista se consolidó como publicación periódica y logró convertirse en un referente de la intelectualidad latinoamericana. Tomando en cuenta la potencialidad de las revistas culturales como fuente para el estudio y análisis de la conformación de redes intelectuales en Latinoamérica, nos proponemos analizar la revista Nosotros partiendo de la hipótesis que, en torno a la misma, se configuró una red integrada por miembros del campo intelectual argentino y americano, que intentó ser reflejo de las ideas predominantes de su época. El presente trabajo pretende exponer los resultados obtenidos a partir del análisis de un corpus que abarca los diez primeros años de su existencia, desde 1907 hasta 1917, atendiendo a los siguientes interrogantes: si es posible definir una red en esta etapa de la revista, quiénes la integraron, cómo se fue gestando, en torno a qué ideas o problemáticas cobró visibilidad.

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.
