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 startingpoint. Chemical compositional data, as used in provenance studies on archaeologicalmaterials, will be approached from the measurement theory. The results will show, in avery intuitive way that chemical data can only be treated by using the approachdeveloped for compositional data. It will be shown that compositional data analysis is aparticular case in projective geometry, when the projective coordinates are in thepositive 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 ofapplications, including shape analysis. This will be exemplified with a case study inarchitecture of Early Christian churches dated back to the 5th-7th centuries AD

Statistics in archaeology: New directions

Connections between Statistics and Archaeology have always appeared veryfruitful. The objective of this paper is to offer an outlook of somestatistical techniques that are being developed in the most recentyears and that can be of interest for archaeologists in the short run.

No es exagerado afirmar que, en las últimas décadas, los estudios dedicados a la cultura material de la antigüedad tardía y, en particular, a sus producciones cerámicas, han experimentado un desarrollo acelerado. Este fenómeno se ha traducido en una auténtica explosión de títulos que, con diversa extensión y profundidad, abarcan todas las posibilidades de análisis: desde las monografías de excavación, en las que se describen los repertorios asociados a las formas de vida y trabajo de un asentamiento, hasta las síntesis regionales que abordan cuestiones relacionadas con los mecanismos económicos, culturales y políticos que impulsaron la creación de unos circuitos de intercambio de alcance mediterráneo.

Díaz-Andreu, Margarita: A world history of nineteenth century archaeology. Nationalism, Colonialism, and the Past.

M. Díaz-Andreu plantea un análisis de las implicaciones académicas, sociales y políticas de la arqueología (entendiendo como tal la investigación estricta, pero también el coleccionismo de obras de arte) entre finales del siglo XVIII y el inicio de la Primera Guerra Mundial, período durante el cual la formación y expansión de los imperios coloniales constituyó uno de los elementos clave en el discurso ideológico de los estados europeos. Su trabajo continúa la línea marcada por estudios suyos anteriores, esencialmente Nationalism and Archaeology in Europe (Díaz-Andreu & T. Champion [eds.], 1996) y Excavating Women. A History in European Archaeology (Díaz-Andreu & M. L. S. Sorensen, 1998), en los que combinaba el análisis historiográfico de diferentes aspectos y personajes clave de la arqueología europea desde la perspectiva de la organización de las redes sociales entre investigadores, con la reflexión sobre las implicaciones de la arqueología como ciencia en la definición y defensa de diferentes credos políticos, y el papel de la mujer en la investigación.

Ancient DNA analysis of 8000 B.C. near eastern farmers supports an early neolithic pioneer maritime colonization of Mainland Europe through Cyprus and the Aegean Islands

The genetic impact associated to the Neolithic spread in Europe has been widely debated over the last 20 years. Within this context, ancient DNA studies have provided a more reliable picture by directly analyzing the protagonist populations at different regions in Europe. However, the lack of available data from the original Near Eastern farmers has limited the achieved conclusions, preventing the formulation of continental models of Neolithic expansion. Here we address this issue by presenting mitochondrial DNA data of the original Near-Eastern Neolithic communities with the aim of providing the adequate background for the interpretation of Neolithic genetic data from European samples. Sixty-three skeletons from the Pre Pottery Neolithic B (PPNB) sites of Tell Halula, Tell Ramad and Dja'de El Mughara dating between 8,700-6,600 cal. B.C. were analyzed, and 15 validated mitochondrial DNA profiles were recovered. In order to estimate the demographic contribution of the first farmers to both Central European and Western Mediterranean Neolithic cultures, haplotype and haplogroup diversities in the PPNB sample were compared using phylogeographic and population genetic analyses to available ancient DNA data from human remains belonging to the Linearbandkeramik-Alföldi Vonaldiszes Kerámia and Cardial/Epicardial cultures. We also searched for possible signatures of the original Neolithic expansion over the modern Near Eastern and South European genetic pools, and tried to infer possible routes of expansion by comparing the obtained results to a database of 60 modern populations from both regions. Comparisons performed among the 3 ancient datasets allowed us to identify K and N-derived mitochondrial DNA haplogroups as potential markers of the Neolithic expansion, whose genetic signature would have reached both the Iberian coasts and the Central European plain. Moreover, the observed genetic affinities between the PPNB samples and the modern populations of Cyprus and Crete seem to suggest that the Neolithic was first introduced into Europe through pioneer seafaring colonization.

Induced maritime accidents

Humanity system of life is highly supported by maritime transport when circa 8 thousand million people require about 8.800 million tons of merchandises by sea, going in some 105.000 merchant ships of over 100 GT, sailing every thinkable dangerous waters 365 days year 24 hours day. All that Enormous activity plus others different factors produce accidents, as is shown in an ascendant 1.7 rate related to ships lost with big number in life, cargoes losses, and pollution. That is why this study pretend to detect causes factors of maritime accidents, to try to reduce them, and with that targetin mind it was tested the new theory of Induced Maritime Accidents, crossing itsproposals with relevant sinister of different times and circumstances, as Andrea Doria, Torrey Canyon, Costa Concordia, among others. Those cases were re evaluated to establish the key points of such theory, as they are the Production Pressure, the Risk Homeostasis, technological advances and the rupture of safety margin. Cases studies gave as result the existence of referred key points, in a manner combined that the chain of events derived to the fatality, and more than that highlights the possibility that been suppressed to acceptable limits the production pressure or the risk homeostasis, a permissible safety margin were been maintained, avoiding catastrophe.
