Revisiting the compositional data. Some fundamental questions and new prospects in Archaeometry and Archaeology

In this paper we examine the problem of compositional data from a different starting point. Chemical compositional data, as used in provenance studies on archaeological materials, will be approached from the measurement theory. The results will show, in a very intuitive way that chemical data can only be treated by using the approach developed for compositional data. It will be shown that compositional data analysis is a particular case in projective geometry, when the projective coordinates are in the positive orthant, and they have the properties of logarithmic interval metrics. Moreover, it will be shown that this approach can be extended to a very large number of applications, including shape analysis. This will be exemplified with a case study in architecture of Early Christian churches dated back to the 5th-7th centuries AD

[Ressenya de la] Conferència internacional The Future of the Mediterranean Rural Environment: Prospects for Sustainable Land Use and Management. Menemen (Turquia), del 8 a l'11 de maig de 2000

Crònica de la conferència internacional 'The Future of the Mediterranean Rural Environment: Prospects for Sustainable Land Use and Management' sobre el desenvolupament sostenible de les àrees rurals mediterrànies. La conferència va tenir lloc entre el 8 i l’11 de maig de 2000 a Menemen (Turquia) i va reunir experts de diverses disciplines per establir els problemes principals que afecten la Mediterrània i per debatre mesures concretes de gestió, evitant o minimitzant els efectes negatius dels canvis econòmics, polítics, tecnològics i mediambientals recents
