We apply GIS techniques to analyze a carefully selected database of 93 Early Neolithic sites in the Iberian Peninsula. This allows us to study the spatial dynamics of the Neolithic transition in Iberia. We study how the Neolithic was introduced into the peninsula in order to test the hypothesis that the Neolithic was introduced almost simultaneously from two sources: one at the northeast (via the Mediterranean coast) and another one at the south (possibly from Northern Africa). We also analyze how the expansion of the Neolithic transition took place within the Iberian Peninsula and measure local rates of spread in order to identify regions with fast and slow rates (such as the slowdown at the Cantabrian coast). In addition, we attempt to reproduce the main results obtained from the GIS analysis by applying reaction–dispersal models to the expansion of the Neolithic transition in the Iberian Peninsula. We conclude that a model with two sources is a reasonable assumption that agrees better with the archaeological data available at present than a model with a single source. 相似文献

Based on archaeological evidence from Kutch-Saurashtra (N Gujarat, NW India), we use agent-based modelling (ABM) to explore the persistence of hunter-gatherer (HG) groups in semi-arid environments in the mid and late Holocene. Agents interact within a realistic semi-arid environment dominated by the monsoon. Precipitation trends are modelled from instrumental records (1871–2008) calibrated with existing models for the Asian monsoon in the Holocene (c. 12 ka–present). Experiments aim at exploring dependencies between population dynamics and climate-driven environmental change (in terms of resource availability) for precipitation patterns at the local, regional and continental scales. Resources are distributed across a simplified ground model. Average yearly precipitation (AYP, i.e. mean) and variance in yearly precipitation (VYP, i.e. standard deviation) are the main parameters affecting resource availability in the simulations. We assess the effects of environmental change on HG populations at different timescales: (1) patterns of seasonal (inter-annual) resource availability, (2) effects of changes in mean precipitation trends over the long (Pleistocene–Holocene) and the mid (Holocene, millennial) periods, and (3) effects of intra-annual precipitation variability, i.e. changes in standard deviation from mean precipitation trends over the short period (annual to decadal). Simulations show that (1) strong seasonality is coherent with the persistence of HG populations in India, independently of the geographical scale of the precipitation models, (2) changes in AYP over the mid period (Holocene) are not sufficient to explain the disappearance of HG populations in Kutch-Saurashtra (K-S) 4 ka and (3) precipitation variability (VYP) over the short period (annual to decadal) is the main parameter affecting population performance and overall ecosystem dynamics. To date, sufficiently refined palaeoclimatic records do not exist for the study area, but higher VYP values 4 ka do not exclude the possibility that other factors may have driven the disappearance of HG populations in Kutch-Saurashtra. 相似文献

Current knowledge about the Mesolithic–Neolithic transition in the Central and Western Mediterranean European regions is deeply limited by the paucity of Late Mesolithic human osteological data and the presence of chronological gaps covering several centuries between the last foragers and the first archaeological evidence of farming peoples. In this work, we present new data to fill these gaps. We provide direct AMS radiocarbon dating and carbon (δ13C) and nitrogen (δ15N) stable isotope analysis were carried out on bone collagen samples of two single burials from the recently discovered open-air Late Mesolithic site of Casa Corona (Villena, Spain). The results shed new light on the chronology and subsistence patterns of the last Mesolithic communities in the Central Mediterranean region of the Iberian Peninsula. Radiocarbon results date the human remains and funerary activity of the site to 6059–5849 cal BC, statistically different from other Late Mesolithic sites and the earliest Neolithic contexts, and bridging the 500 yrs chronological gap of the Mesolithic–Neolithic transition from the area. Isotopic evidence shows that diet was based on terrestrial resources despite the proximity to the site of lagoon and marine ecosystems. This and previous isotope studies from the region suggest a lower reliance upon marine resources than for Atlantic and Cantabrian sites, although intra-regional patterns of neighbouring Mesolithic populations exhibit both fully terrestrial diets and diets with significant amounts of aquatic resources in them. We hypothesize that in the Central Mediterranean region of Spain the Late Mesolithic dietary adaptations imposed structural limits on demographic growth of the last foragers and favoured rapid assimilation by the earliest Neolithic populations. 相似文献

Urban developments can transform adjacent rural areas by degrading their natural resource base and environmental values. In this paper we provide evidence on the implementation of an endogenous sustainable development plan for the rural–urban environment in the city of Las Palmas de Gran Canaria. The objective was the generation of endogenous development in the rural areas by implicating the local population in developing activities in line with natural values and the recuperation of traditional cultures. At the same time, urban societies were expected to benefit from the preservation and availability of these rural environments. The plan was implemented in a large rural valley located between adjacent urban areas. The valley represents an opportunity for urban dwellers to benefit from a large rural park in the urban environment for leisure and cultural activities. The overall accomplishment of the plan was evaluated and contrasted with the benefits to the urban population, which were also measured with a discrete choice experiment. The results highlight that the principal objectives failed because of the lack of political determination to promote the participatory channels that would lead to the preservation of natural resources in a dynamic process of social change. 相似文献

In recent decades, indigenous populations have become the subjects and agents of development in national and international multicultural policy that acknowledges poverty among indigenous peoples and their historic marginalization from power over development. Although the impact of these legal and programmatic efforts is growing, one persistent axis of disadvantage, male–female difference, is rarely taken into account in ethno-development policy and practice. This article argues that assumptions that inform policy related to indigenous women fail to engage with indigenous women's development concerns. The institutional separation between gender and development policy (GAD) and multiculturalism means that provisions for gender in multicultural policies are inadequate, and ethnic rights in GAD policies are invisible. Drawing on post-colonial feminism, the paper examines ethnicity and gender as interlocking systems that structure indigenous women's development experiences. These arguments are illustrated in relation to the case of the Tsáchila ethno-cultural group in the South American country of Ecuador. 相似文献

The sun, sea and sand model that has characterized the Spanish tourism sector and has caused Spain's tourist sector to become a world-class industry is actually undergoing drastic changes. This model is based on the existence of major tourism destinations characterized by high levels of industry specialisation, which makes them a target of analysis as tourism clusters in which the geographic concentration of synergies reinforces the competitive position. In this study, Spanish tourism clusters are identified using quantitative methods and the current validity of the economies of location that have made them possible are also analysed. Although all the identified clusters can be defined as mature and became less significant during the last decade in Spanish tourism, according to the results the creation of externalities measured in terms of higher generation of profit is higher in companies belonging to the tourism clusters than in those outside of them. 相似文献

This study was aimed at individuating characteristics related to the pottery’s firing technique of Classical Roman producers, through the low field single-sided NMR relaxometry. The approach is based on a recent method of analysis, the correlation of the longitudinal and transverse NMR relaxation times of a liquid probe (in this case distilled water) filling the porous system of ceramics. The analyzed findings form two homogeneous classes with dating and place of production well established through the producer trademarks. Pottery findings belong to the black-slipped pottery productions of the Latin ancient city of Praeneste between third and second century B.C. and have been attributed to two different ”patriziae” production families: gens Samiaria and gens Trebonia. A further fragment with Greek kylix style, found in the same archaeological area, has also been analyzed, in order to understand if it had been imported from Greece, or made in Praeneste in imitation of the Greek style. 相似文献

The retrospective diagnosis of illnesses by medical historians can often be difficult and prone to bias, although knowledge of the medical disorders of historical figures is key to the understanding of their behavior and reactions. The recent application of computer diagnostics to historical figures allows an objective differential diagnosis to be accomplished. Taking an example from clinical neurology, we analyzed the earliest reported cases of Devic’s disease (neuromyelitis optica) that commonly affects the optic nerve and spinal cord and was previously often confused with multiple sclerosis. We conclude that in most identified cases the software concurred with the contemporary physicians’ interpretation, but some claimed cases either had insufficient data to provide a diagnosis or other possible diagnoses were suggested that had not been considered. Computational methods may, therefore, help historians to diagnose the ailments of historical figures with greater objectivity. 相似文献

Los obstáculos impuestos a los americanos para entrar a la Compañía de Jesús fueron una constante en la Nueva España durante el generalato de Claudio Acquaviva (1581–1615). Si bien aquellos pueden ser considerados como la prolongación de un debate que había comenzado con la llegada de los primeros franciscanos en 1524, y como parte de tensiones que existían a nivel global sobre la viabilidad de aceptar no europeos en las órdenes religiosas, esta cuestión evolucionó conforme a los nuevos estándares de la Iglesia postridentina, y a los cambios sociales y políticos del virreinato. Las tensiones provocadas por diversos grupos sociales emergentes al reclamar sus propios espacios dentro de la sociedad novohispana, ocasionaron que la discusión en torno a la creación de un clero indígena se subsumiera en una serie de pugnas entre diferentes facciones de la Compañía de Jesús, bajo la sombra de los poderes de la Corona española y Roma. Así, en una época en donde la Compañía de Jesús se debatía sus prioridades apostólicas con la disyuntiva colegios/misiones, el caso de la Provincia de México nos muestra cómo este problema estuvo inmerso en una lucha de bandos por los puestos de poder. 相似文献
