Jean-Martin Charcot - Neurologist by Avocation, Nephrologist by Yearning

In an age of medical advances and specialization, Jean-Martin Charcot (1825-1893) helped found the discipline of neurology and in 1882 was appointed the first professor of Diseases of the Nervous System in France. As an investigator with broad interests and vast knowledge Charcot contributed to several other disciplines. An early mentor and dominant figure in Charcot's formative years was Pierre Rayer (1793-1867), famous for his seminal contributions to the study of the kidney, who gifted Charcot with his passion for clinical pathological correlations and likely a yearning for the study of kidney diseases. Famous for the clarity and incisiveness of his formal teaching presentations, Charcot lectured on the kidney at the Faculty of Medicine in Paris in 1877. Translated into English and published as a book titled Lectures on Bright's Disease, they became widely accessible and quoted in the literature through the present. In addition, at a time that he was already concentrating on the study of neurological disorders, Charcot maintained his life-long interest in the kidney and published original studies on the pathological changes of the kidney in gout and experimental lead poisoning, as well as supporting a study of hysterical ischuria by his students.

Persona y naturaleza : de Pedro Lombardo a Martin Heidegger

Pese a los indicios que podrían encontrarse en la filosofía griega, la noción de persona es de origen netamente cristiano y no pudo haber sido formulada sino dentro de ese horizonte de pensamiento. El hombre ha sido creado a imagen de Dios y es persona porque, en primer término, Dios lo es. Aquí se enlazan, durante el medioevo, las cuestiones antropológicas y teológicas (trinitarias y cristológicas). Un ejemplo paradigmático se encuentra en las Sentencias de Pedro Lombardo y sus comentadores, entre los que hemos reparado especialmente en Tomás de Aquino. En este contexto, “naturaleza" (divina o humana) y “persona" son nociones íntimamente vinculadas, pues es propio de tales naturalezas el existir y manifestarse como seres personales. Esa relación, sin embargo, se pierde durante la modernidad, época en que persona y naturaleza se vuelven términos antagónicos. Martin Heidegger, agudo crítico de esa transformación en la historia del pensar, propone una concepción de lo humano que, no obstante su “ateísmo metodológico", finalmente parece aproximarse a la noción cristiana de persona.

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.
