The Chronology of Archaeological Assemblages Based on Automatic Bayesian Procedure: Eastern Iberia as Study Case
2021
The purpose of this work is to show an automatic Bayesian procedure to obtain accurate chronological information of archaeological assemblages characterized by palimpsest or neither radiocarbon dates and whose temporal information comes only from bifacial flint arrowheads.In this work, a classification based on the Dirichlet-multinomial inferential process and its posterior predictive probability distribution are applied. Its purpose is to predict the chronological period of archaeological assemblages (levels or sites) based on the predictive probability distribution of each bifacial flint arrowhead types defined in the Eastern Iberia during the 4th and 3rd millennium cal BC. The results of…
La formació del plural i la situació del gènere en el «Curial e Güelfa» dins del context del segle XV
2007
We study the situation of plurals in the «Curial e Güelfa» and, by extension, in the Catalan of the 15th century, analyzing particularly the possible subordinating factors of the distribution of plurals -es and -os of masculine words that finish in -s. The situation of plurals helps to confirm the dating of the novel in the middle of the 15th century. On the other hand, in the section of inflection of gender, the presence of forms that confirm the classicism of the novel is evident, as well as some Valencian preferences.
Corundum Anorthosites-Kyshtymites from the South Urals, Russia: A Combined Mineralogical, Geochemical, and U-Pb Zircon Geochronological Study
2019
Kyshtymites are the unique corundum-blue sapphire-bearing variety of anorthosites of debatable geological origin found in the Ilmenogorsky-Vishnevogorsky complex (IVC) in the South Urals, Russia. Their mineral association includes corundum-sapphire, plagioclase (An61&ndash
On the Rock Partridge in the painting “Saint Jerome in the study” by Antonello da Messina.
2012
Pictorial work of Antonello da Messina during the Sicilian period (1455-60) is considered less fruitful and less mature than during his stay in Venice (ca 1474-1476). While some art critics consider the painting “Saint Jerome in the study” a work of the first period, others believe that it was produced during the Venice period. The Authors analysed the plumage characters of the Rock Partridge, Alectoris graeca, depicted with symbolic significance in the painting, to try the identification of the population which the subject used as model could belong to. However, they conclude that the identification as a Sicilian as well as an Alpine Rock Partridge is doubtful and in this case the plumage …
Dating of Archaeological Gold by Means of Solid State Electrochemistry
2018
[EN] In archaeology and history of art, age determination is a fundamental analytical problem. While several techniques for age determination of various materials, like radiocarbon dating, are established, these methods cannot be applied for metals, for which new techniques have to be developed. For the first time a dating method for archaeological gold objects is described which is based on a corrosion clock and electrochemical measurements, using the voltammetry of immobilized particles. Samples are prepared by one touch' with a graphite pencil, only transferring a few nanograms of the archaeological gold. The method has been calibrated with the help of a series of well-documented gold sp…
Dating archaeological strata in the Magna Mater temple using solid-state voltammetric analysis of leaded bronze coins
2017
[EN] The application of solid state electrochemistry techniques for dating archaeological strata using lead-containing bronze coins is described. The proposed methodology was applied to samples coming from the Roman archaeological site of Magna Mater Temple (Rome, Italy) occurring in different strata dating back between the second half and the end of the 4(th) century A.D. and the 20(th) century. The voltammetric signatures of copper and lead corrosion products in contact with aqueous acetate buffer, as well as the catalytic effects produced on the hydrogen evolution reaction, were used for establishing the age of different strata and dating coins belonging to unknown age. Voltammetric data…
Data from: The legacy of a vanished sea: a high level of diversification within a European freshwater amphipod species complex driven by 15 My of Par…
2015
The formation of continental Europe in the Neogene was due to the regression of the Tethys Ocean and of the Paratethys Sea. The dynamic geology of the area and repetitious transitions between marine and freshwater conditions presented opportunities for the colonization of newly emerging hydrological networks and diversification of aquatic biota. Implementing mitochondrial and nuclear markers in conjunction with a large-scale sampling strategy, we investigated the impact of this spatiotemporal framework on the evolutionary history of a freshwater crustacean morphospecies. The Gammarus balcanicus species complex is widely distributed in the area previously occupied by the Paratethys Sea. Our …
Contexto-A: Programa de intervención en violencia de género en jóvenes con medidas judiciales
2017
Resumen Tesis Doctoral: Contexto-A: Programa de intervención en violencia de género en jóvenes con medidas judiciales M. Victoria Lorenzo López INTRODUCCIÓN La violencia contra la pareja en las relaciones de jóvenes y adolescentes o dating violence, ha sido definida por varios autores como todo acto o ataque intencional de tipo físico, psicológico o sexual de un miembro de la pareja contra el otro, en una relación romántica en la que no existe vínculo legal ni cohabitación (Póo y Vizcarra, 2011; Rubio-Garay, López-González, Saúl y Sánchez-Elvira-Paniagua, 2012). Aunque comparte elementos comunes con la violencia ejercida en las relaciones adultas, requiere de intervención y tratamiento espe…
Spatial Cognition 2020/1: Book of abstracts : August 2-4, 2021, University of Latvia
2021
Spatial Cognition is concerned with the acquisition, development, representation, organization, and use of knowledge about spatial objects in real, virtual or hybrid environments and processed by human or artificial agents. Spatial Cognition includes research from different fields insofar as they are concerned with cognitive agents and space, such as cognitive and developmental psychology, linguistics, computer science, geography, cartography, philosophy, neuroscience, and education. Research issues in the field range from the investigation of human spatial cognition to mobile robot navigation, including topics such as wayfinding, spatial planning, spatial learning, internal and external re…
A revision of the structure and stratigraphy of pre-Green Tuff ignimbrites at Pantelleria (Strait of Sicily)
2013
International audience; At Pantelleria, peralkaline silicic magmas were erupted across a range of eruptive typologies and magnitudes: pyroclastic flows, Plinian to strombolian pumice fallout and lava flows. In this paper we focus on the intermediate cycle of eruptive activity which is bracketed by ignimbrite units slightly older than the two caldera collapses which marked the volcanological activity of the island. This age interval (180-85 ka) was punctuated by six ignimbrite-forming eruptions (silicic and variably peralkaline) for a cumulative erupted magma volume of approximately 6 km3 dense rock equivalent. Based on new 40Ar/39Ar (Na,K)-feldspar ages and petrographic data, we propose an …
