Es historia conocida el rol crucial que tuvieron los diecinueve electores de la provincia de Santa Fe en la elección del presidente en 1916. Después de algunas marchas y contramarchas, estos hombres pertenecientes al Radicalismo «disidente» santafesino volcaron sus votos en favor de Yrigoyen, otorgándole la mayoría en el colegio electoral necesaria para su consagración como presidente. Sin embargo, conocemos menos de la trama que posibilita este desenlace. Es allí donde este trabajo se detiene: en la coyuntura pautada por las elecciones a gobernador de la provincia de Santa Fe, de febrero de 1916, las presidenciales de abril de ese mismo año, y la reunión del colegio electoral en junio para elegir la fórmula presidencial. Interesa reconstruir el juego político en el distrito provincial santafesino, en esa coyuntura que tiene como nota sobresaliente el «estreno» de la ley Sáenz Peña en la elección de presidente, a través del análisis del comportamiento del Radicalismo, partido que detenta el poder provincial desde 1912, y que en la coyuntura estudiada se encuentra dividido entre «oficialistas» y «disidentes».

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.
