Sobre el origen y difusiĂłn del NeolĂtico en la PenĂnsula IbĂ©rica, ca. 5600-5000 cal a.C.
Desde la dĂ©cada de los años 90 del pasado s. XX los estudios sobre el NeolĂtico vivieron una autĂ©ntica revoluciĂłn empĂrica. Fruto de proyectos de investigaciĂłn programados e intervenciones de urgencia, se excavaron y dieron a conocer una amplia serie de nuevas estaciones ubicadas dentro y, sobre todo, fuera de las regiones “clásicas”: el área mediterránea peninsular.
Esta ampliaciĂłn de la base documental que incluye tambiĂ©n, por primera vez, y de manera destacada a Portugal, debiera permitir la evaluaciĂłn de los modelos propuestos para explicar la neolitizaciĂłn. Sin embargo, esto no resulta exactamente asĂ. Sabemos que los niveles de los yacimientos prehistĂłricos distan mucho de ser contextos cerrados

Indigenismo y migracionismo. Aspectos de la neolitizaciĂłn en la fachada oriental de la PenĂnsula IbĂ©rica
This paper discusses various aspects on the origins of the Neolithic in the Iberian Peninsula. The dual model is proposed as an alternative to the dichotomy of demie (migrationist) and non-demic (indigenist) explanations. The application of this model in eastern Spain offers an opportunity to evaluate its potential to account for diversity in processes associated with the origins of food production and their spatial organisation.Este trabajo trata algunos aspectos relativos al origen del NeolĂtico en la PenĂnsula IbĂ©rica. En el mismo se propone el modelo dual como alternativa a la dicotomĂa entre las posturas que asumen puntos de vista basados en el movimiento de personas (migracionistas) o de ideas/bienes (indigenistas). Su aplicaciĂłn a la fachada oriental del Mediterráneo español permite evaluar sus posibilidades, apostando por una mayor complejidad y una lectura territorial del proceso de neolitizaciĂłn

Mas d’Is (Penà guila)
Las diferentes actuaciones llevadas a cabo durante los años 2010 y 2011 en el yacimiento neolĂtico del Mas d’Is (PenĂ guila) han permitido avanzar en el conocimiento de este yacimiento de referencia de las primeras comunidades agrĂcolas de la PenĂnsula IbĂ©rica. Las campañas previas habĂan revelado la existencia de algunas estructuras enormes en el extremo norte del yacimiento; el trabajo más reciente se ha centrado en el denominado "Foso 4". Los resultados fueron mejores de lo esperado.Archaeological works at the site of Mas d’Is (PenĂ guila, Alacant) have revealed important deposits dating back to the Early Holocene. The 2010 and 2011 field seasons at theNeolithic site is one of the key projects that the Department of Prehistory and Archaeology at the University of Valencia carries out in the region. Previous campaigns had revealed the existence of some huge structures at the northern end of the site; the most recent work was focused in the so-called “Foso 4”. There results were better than expected.Informe de las excavaciones del año 2011 en el yacimiento del Mas d'I
A survey on elasticity management in PaaS systems
[EN] Elasticity is a goal of cloud computing. An elastic system should manage in an autonomic way its resources, being adaptive to dynamic workloads, allocating additional resources when workload is increased and deallocating resources when workload decreases. PaaS providers should manage resources of customer applications with the aim of converting those applications into elastic services. This survey identifies the requirements that such management imposes on a PaaS provider: autonomy, scalability, adaptivity, SLA awareness, composability and upgradeability. This document delves into the variety of mechanisms that have been proposed to deal with all those requirements. Although there are multiple approaches to address those concerns, providers main goal is maximisation of profits. This compels providers to look for balancing two opposed goals: maximising quality of service and minimising costs. Because of this, there are still several aspects that deserve additional research for finding optimal adaptability strategies. Those open issues are also discussed.This work has been partially supported by EU FEDER and Spanish MINECO under research Grant TIN2012-37719-C03-01.Muñoz-EscoĂ, FD.; Bernabeu Aubán, JM. (2017).

Sequence and context for the Cocina cave neolithic pottery: An approach from social networks analysis
Cocina cave has been considered one of the main sites when explaining the transition from Mesolithic to Neolithic in the Iberian Mediterranean façade. But the current review of its stratigraphy has evidenced important post-depositional disturbances affecting those layers where Neolithic pottery is present. These taphonomic problems question the usefulness of this record in any detailed approach to a potential process of acculturation of the local Mesolithic groups. Despite this negative preservation, and using decorative traits as a proxy, we have isolated two ceramic contexts with inner coherence. Over these contexts, we have developed a Bayesian approach to compare them with other well-dated regional contexts. To contextualise the obtained sequence, we decided to extend the analysis to a wide set of Neolithic known contexts from an area that covers most of the coastal Iberian Mediterranean region, from the Ebro basin in the North to the Segura basin in the South. These contexts have been organised in chronological windows, and a Social Networks Analysis (SNA) has been applied. Results confirm the insertion of Cocina in the regional Neolithic dynamics. After the first stage, with an important degree of cultural homogeneity, the analysis also outlines the existence of a cultural frontier among Neolithic groups North and South of the Xúquer basin, at least from the mid-seventh millennium cal BP
El color en las producciones cerámicas del NeolĂtico antiguo
En las Ăşltimas dĂ©cadas se ha venido destacando la existencia de unas determinadas producciones cerámicas, durante el NeolĂtico Antiguo, dotadas de un importante valor simbĂłlico. En el presente trabajo profundizamos en la relaciĂłn existente entre una serie de variables uso de colorante, tĂ©cnicas decorativas, tipologĂa que nos permiten considerar la presencia de una serie de asociaciones significativas. Ello nos hace pensar que los tipos decorativos o el uso de colorante no se produce de manera aleatoria. A partir de estos datos valoramos la posible existencia de diversas producciones especĂficas que van más allá de las cerámicas simbĂłlica
Programa de prospecciĂłn geofĂsica, microsondeos y catas para la caracterizaciĂłn de un gran foso del IV milenio cal AC en Alt del PunxĂł (Muro de L’Alcoi, Alacant)
The potentially long and interesting archaeological sequence revealed by systematic survey at the site of Alt Del PunxĂł (Muro de l’Alcoi, Alacant) was the basis for initiating a study of the locality’s subsurface structures using new methods of remote sensing. Geophysical survey (magnetometry and tomography) and systematic augering revealed buried structures, including monumental earthworks, and guided subsequent excavations to collect more detailed data about the nature and age of these prehistoric features. The information recovered, including new radiocarbon dates, offers a new perspective on the organization of prehistoric populations in this region of south-central Valencia since the beginning of the Holocene and is especially important for understanding the Neolithic IIB from the 4th through the early 3rd Millennium BC.La amplia e interesante secuencia arqueolĂłgica sugerida por los materiales de superficie del yacimiento de Alt del PunxĂł (Muro de l’Alcoi, Alacant) ha supuesto el punto de partida para la práctica de una serie de mĂ©todos de detecciĂłn de las estructuras conservadas en el lugar. La prospecciĂłn geofĂsica (magnetometrĂa y tomografĂa), y los microsondeos (augers) han dirigido la planificaciĂłn de la excavaciĂłn con el fin de obtener nuevos datos a propĂłsito de la naturaleza y cronologĂa del gran foso prehistĂłrico, asĂ como de las diversas estructuras localizadas. La informaciĂłn obtenida, junto a la serie radiocarbĂłnica disponible, abre nuevas perspectivas para el estudio del poblamiento prehistĂłrico al aire libre en las comarcas centro-meridionales valencianas desde los inicios del Holoceno, y de un modo particular en el IV e inicios del III milenio cal AC –NeolĂtico IIB
