Il trattato ‘Practica musice’ di Franchino Gaffurio (1496). Genesi, tradizione del testo, trascrizione interpretativa e traduzione.

La ricerca consiste nell’edizione e traduzione del trattato ‘Practica musice’ di Franchino Gaffurio corredata da apparati critici e storico-contestuali. Si inizia con la biografia dell’autore redatta secondo gli ultimi dati disponibili e si presenta una esposizione del contenuto del trattato con proposte di chiarimenti dei passi più oscuri. Segue quindi uno studio dei cambiamenti intercorsi tra le parti del trattato come trasmesse nei manoscritti preparatori e la sua versione finale a stampa, seguito da una indagine sulle edizioni successive all’editio princeps, con tabelle sulle varianti tra le edizioni. Vengono quindi offerte la trascrizione interpretativa del testo latino del trattato (che può essere considerata la più corretta attualmente disponibile ed è l’unica a riportare numeri di partizione testuale) seguita dalla sua traduzione in italiano, con trascrizione degli esempi musicali. Il trattato, diviso in quattro libri, ha per argomenti rispettivamente il cantus planus e le scale modali gregoriane, la musica misurata e le figure della notazione, l’arte del contrappunto e la più ampia casistica disponibile sulle proporzioni ritmiche.

Review of Clément Vidal, "The Beginning and the End. The Meaning of Life in a Cosmological Perspective"

No more ground control. Dissertations ideally always have been ambitious, and this one can’t claim to be too humble in these regards. Together the pieces of this work form a world view that the author confesses to finding ‘magnificent’. The story he tells is one in which intelligence and complexity are keys to unlock the universe’s mysteries. Vidal tackles questions like ‘What is philosophy?’, ‘Where does it all come from?’, Where are we going?’, ‘Are we alone in the universe?’ and even ‘What is good and what is evil?’. Questions which philosophers for ages have tried to answer.

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.
