Aportaciones al proceso de iberización en el curso inferior del Ebro: el ejemplo de Sebes (Flix, Ribera d’Ebre, Tarragona)

Presentamos en este trabajo el resultado de las intervenciones efectuadas en el yacimiento de Sebes entre los años 2010 y 2011, donde hemos podido documentar la existencia de un asentamiento ibérico de nueva planta fechado en la segunda mitad del siglo vi a.C., poco tiempo después del abandono del asentamiento del Hierro I, ubicado en la parte más alta de la colina de Sebes. La proximidad entre los dos asentamientos y los restos materiales recuperados parecen indicar un ligero traslado poblacional, dentro de una dinámica interna de cambio en la sociedad ibérica, en una etapa de transición previa a la consolidación de un nuevo modelo poblacional durante el siglo v a.C.

Rapid and sudden advection of warm and dry air in the Mediterranean Basin

Rapid advection of extremely warm and dry air is studied during two events in the Mediterranean Basin. On 27 August 2010 a rapid advection of extremely warm and dry air affected the northeast Iberian Peninsula during a few hours. At the Barcelona city center, the temperature reached 39.3 ° C, which is the maximum temperature value recorded during 230 yr of daily data series. On 23 March 2008 a rapid increase of temperature and drop of relative humidity were recorded for a few hours in Heraklion (Crete). During the morning on that day, the recorded temperature reached 34 °C for several hours on the northern coastline of this island.According to the World Meteorological Organization none of these events can be classified as a heat wave, which requires at least two days of abnormally high temperatures; neither are they a heat burst as defined by the American Meteorological Society, where abnormal temperatures take place during a few minutes. For this reason, we suggest naming this type of event flash heat. By using data from automatic weather stations in the Barcelona and Heraklion area and WRF mesoscale numerical simulations, these events are analyzed. Additionally, the primary risks and possible impacts on several fields are presented.

Deep incision in an Aptian carbonate succession indicates major sea-level fall in the Cretaceous

Long-term relative sea-level cycles (0 5 to 6 Myr) have yet to be fully understood for the Cretaceous. During the Aptian, in the northern Maestrat Basin (Eastern Iberian Peninsula), fault-controlled subsidence created depositional space, but eustasy governed changes in depositional trends. Relative sea-level history was reconstructed by sequence stratigraphic analysis. Two forced regressive stages of relative sea-level were recognized within three depositional sequences. The first stage is late Early Aptian age (intra Dufrenoyia furcata Zone) and is characterized by foreshore to upper shoreface sedimentary wedges, which occur detached from a highstand carbonate platform, and were deposited above basin marls. The amplitude of relative sea-level drop was in the order of tens of metres, with a duration of <1 Myr. The second stage of relative sea-level fall occurred within the Late Aptian and is recorded by an incised valley that, when restored to its pre-contractional attitude, was >2 km wide and cut 115 m down into the underlying Aptian succession. With the subsequent transgression, the incision was back-filled with peritidal to shallow subtidal deposits. The changes in depositional trends, lithofacies evolution and geometric relation of the stratigraphic units characterized are similar to those observed in coeval rocks within the Maestrat Basin, as well as in other correlative basins elsewhere. The pace and magnitude of the two relative sea-level drops identified fall within the glacio-eustatic domain. In the Maestrat Basin, terrestrial palynological studies provide evidence that the late Early and Late Aptian climate was cooler than the earliest part of the Early Aptian and the Albian Stage, which were characterized by warmer environmental conditions. The outcrops documented here are significant because they preserve the results of Aptian long-term sea-level trends that are often only recognizable on larger scales (i.e. seismic) such as for the Arabian Plate.

Forma Conventus Tarraconenesis I: Baetulo-Blanda. La primera carta arqueològica de la Península Ibèrica

Josep de Calasanç Serra i Ràfols va dedicar una part molt important de la seva vida professional a la topografia arqueològica, als arxius del Servei d’Investigacions Arqueològiques de l’Institut d’Estudis Catalans i a fer el seguiment de la descoberta i l’evolució dels jaciments arqueològics del país. En consonància amb aquesta labor, el 1928 va publicar la primera carta arqueològica de la península Ibèrica, una de les primeres corresponents al programa Forma Orbis Romani, de la Unió Acadèmica Internacional. Després de la Guerra Civil, proposem que fou el principal redactor de la Carta Arqueológica de España. Barcelona, que representa la tercera carta arqueològica publicada a la península Ibèrica.

Factors that determine the evolution of high-growth businesses

The study herein discusses research aimed at elucidating the factors that contribute to a business' ability to maintain high growth. The database from the Iberian Balance Sheet Analysis System (SABI, from its initials in Spanish) was used to identify 250 industrial Catalonian businesses with high growth during 2004-2007. These companies participated in a survey on strategies and management practices; in 2013, they were re-analyzed to investigate the factors that contributed to continued growth for certain companies. Through diverse statistical techniques, business policies related to quality, innovation, internationalization and finance were shown to influence business growth and sustainability over time. High-growth businesses have been studied throughout the world, but this is the first study to investigate the evolution of businesses after a high-growth phase.

Sobre un modelo constructivo de la arquitectura ibérica en territorio Ausetano

En este trabajo presentamos el estudio arquitectónico de un tipo de construcción identifi cado en el territorio ibérico ausetano. A partir del análisis constructivo de tres obras defensivas militares identifi cadas como murallas de compartimentos (Turó del Montgròs, Casol de Puigcastellet y l’Esquerda), planteamos una propuesta de restitución del diseño arquitectónico de estas construcciones basadas en el uso de formas geométricas simples y en la adición de módulos cuadrangulares.

La integración de Tarrakuna y su territorio en al-Andalus (s. VIII)

A inicios del siglo VIII, el antiguo regnum gothorum se vio fragmentado en diferentes territorios políticos, como muestra la simultaneidad de dos reyes (Rodrigo y Akhila) entre 710-711. Con la conquista islámica de la Península Ibérica y la formación de al-Andalus, las diversas regiones conocieron distintos destinos: algunas aristocracias pactaron con los conquistadores, otras se vieron sometidas por la fuerza. Pero la tradición historiográfica ha visto en la ciudad de Tarragona una excepción, un caso aislado. El objetivo de este artículo es plantear una nueva hipótesis, según la cual, durante todo el siglo VIII, madinat Tarrakuna formó parte del Estado andalusí de la misma forma que otras antiguas sedes episcopales visigodas.

Adaptació metrològica grega en l'arquitectura ibèrica de Catalunya: Puig de Sant Andreu d'Ullastret i Mas Castellar de Pontós

En el presente artículo se analiza la adopción en el contexto ibérico catalán de los patrones métricos característicos de las colonias griegas del Mediterráneo occidental. La determinación de la unidad de medida constructiva empleada, así como de su aplicación, ha sido posible mediante la identificación de los principios geométricos estructurales de las torres defensivas ibéricas.

Coronilla repanda (Poir.) Guss. subsp. dura (Cav.) Cout. and Ranunculus nodiflorus L. are indicated for the first time in Catalonia

Domestic architecture and social differences in North-Eastern Iberia during the iron age (c.525-200 BC)

This paper is concerned with the organization of societies in north-eastern Iberia (present-day Catalonia) during the Iron Age, using data provided by domestic architecture and settlement organization. I offer an analysis of the social differences detected in the dwellings based on a sample of houses excavated at different types of settlement. Although many Iberian houses had simple layouts and small surface areas, some larger dwellings at the main sites are distinguished by the shape of their ground plans, their surface areas, architectural features, and central locations; these houses are believed to be the residences of the Iberian elite. Such dwellings are not found at all sites and the data suggest that there was a relationship between the category of the settlement (or its function) and the types of dwelling in it.

Settlement evolution, field systems and sedimentary processes in a Mediterranean mid-mountain (Montseny Massif, Catalunya)

This paper presents the first results of a current research project about human – environmental interactions in the Montseny Massif. Our work sets out to integrate two research lines in the studied area: - Archaeological and archaeo-morphological surveys in a lower part of the mountains in order to characterize the evolution of the settlements and field systems. - The geological and geomorphological characterization of the slope and terrace deposits in relation with field systems and archaeological data. First results point out the intensive occupation of these inland areas during the Iberian and the Roman periods. Post-Roman sediments show different processes of erosion.

Hispania en las provincias occidentales del imperio durante la república y el alto imperio: una perspectiva arqueológica

El siguiente trabajo repasa los procesos y acontecimientos clave de la incidencia de Roma en la península Ibérica –en las denominadas «provincias hispanas»–, con especial atención al espacio comprendido entre el desembarco de Escipión en Emporion (218 a.C.) y el reinado de Adriano, por tanto, durante la República y el Alto Imperio. A partir de la documentación arqueológica y, en ocasiones, epigráfica, se esboza un panorama de la romanización peninsular partiendo de los acontecimientos más representativos de la misma y de sus huellas más evidentes. De igual modo, la bibliografía ofrecida pretende aportar la luz de las últimas novedades sobre la cuestión.

Los inicios de la conquista romana de Iberia: los campamentos de campaña del curso inferior del río Ebro
