The present paper analyses tourist experience, studying the existing differences among geographical zones within a broader tourist destination with provincial character. Planning and management of tourist destinations must pay special attention to the maintenance and conservation of natural and artificial resources in tourist supply, attempting to improve their competitive position. Hence, this study compares several Andalusian coastal municipalities through different components of tourist supply. Among other obtained results, findings indicate the existence of significant differences in urban environments among the municipalities of Almeria, in beach quality among the municipalities of Cadiz and in accommodation among the municipalities of Malaga.  相似文献

Urban sprawl has a major impact on the environment, public health and the socio-economic evolution of cities. The causes are numerous, being mainly related to the generalized use of the automobile in modern cities. Urban sprawl has been especially relevant in US cities since the 1950s, rapidly spreading to other cities in the rest of the world. This paper studies the case of Spain using recent data. Spanish cities have grown rapidly over the 90s and 2000s. The country has completed the process of urbanization and has suffered the effects of a major real estate bubble. In this context, we are interested in measuring and explaining where and why urban sprawl has appeared in Spanish cities. Digital mapping carried out around the year 2000 providing full coverage of Spain is used to calculate an Urban Sprawl Index. It is applied to all urban areas and municipalities throughout the country, providing an objective, comparable measurement of sprawl and identifying which areas are most affected by this phenomenon. A second stage of analysis is conducted in an attempt to explain the causes of the differences in sprawl among Spanish cities with a regression model based on the literature. We have found that the cases most affected by sprawl are the latest urban developments on the Mediterranean coast as well as certain areas in the vicinity of large cities: the mountains to the north of Madrid and the coastline near Barcelona and Valencia. In some cases, urban sprawl is starting to become a problem for the environment and urban sustainability, with important consequences for the future evolution of the affected cities.  相似文献

This paper investigates the different roles played by universities and technology institutes (TIs) as innovation partners of firms. Comparing the characteristics of Spanish firms collaborating with these agents allows us to better define complementarities among the target groups of these organizations. Our findings show that those firms collaborating with universities are bigger, have higher internal capabilities and are less dependent on their external relationships while firms collaborating with TIs are smaller, have weaker internal capabilities but are more open to their environment and thus more reliant on external sources. We point to the implications of these findings for regional development. Universities have a role as partners of more technologically advanced firms. TIs, on the other hand, partner those firms, which though also quite advanced, require more external help in their innovation processes. These results should help policy-makers in the definition of more complex regional strategies and the provision of tools aimed at different goals. Managers of universities, TIs and client firms should find these results of help in developing more positive collaborations with one another.  相似文献

This paper analyses the importance of the South Central Andean High Puna megapatch, above 4000 masl, in the history of late Pleistocene exploration and colonization of the Atacama Desert, including the contrasting habitats that exist towards the hyperarid Pacific Ocean coast or the ecosystems bordering the tropical forests, on the western and eastern sides of the Andes, respectively. These ecosystems, which were firmly established by the end of the Pleistocene, are examined as key factors in the history of human peopling. The social, demographic and climate conditions associated with the peopling processes are discussed in relation to the appropriate technological, subsistence and settlement strategies developed by pioneer populations, who for their initial settlement selected highly productive patches where water and fauna converged. Based on concepts derived from metapopulation theory, all relevant archaeological paleoecological data from both sides of the Andean Cordillera are presented and discussed. It is concluded that the pioneer occupation of the high Puna megapatch was a gradual process, related to an emergent Andean human mobility system that connected a wide range of altitudinally staggered habitats. Moreover, we suggest that divergent cultural trajectories evolved since the early Holocene, affecting highland, lowland and coastal habitats.

The preservation of earthen architectural heritage is extremely complex due to the diversity of its constituent materials and potentially rapid physical deterioration. Interventions on historic earthen architecture throughout the world have shown very distinct levels of success, but there is no single procedure or combination of conservation procedures that guarantee success. One of the problems is the lack of knowledge about the behaviour of soil as the material component, and its relationships both with other materials, and associated natural and cultural environments. This article analyses some technical considerations that have influenced the preservation of earthen archaeological remains, through critical analysis of the existing bibliographic references from the proceedings of specialized international conferences that have taken place in the last twenty years.  相似文献

The main goal of this paper is to review the earliest archaeological evidence for the presence of humans in Fuego-Patagonia. The paleoenvironmental and paleoclimatic framework is briefly introduced, followed by a discussion of its relevance to understanding the exploration and colonization of Fuego-Patagonia. Technological and faunal evidence from a number of sites from the southern extreme older than 10,000 B.P. is analyzed. This leads to the conclusion that an early entry, at least 12,000 years old, appears best to accommodate the available chronological evidence. On the other hand, data from the Northern fringes of Patagonia clearly suggest an earlier human colonization.  相似文献

Archaeosediments are deposits with a direct or indirect anthropogenic component. They provide useful information about past human activities and interaction with the environment. When other materials, such as pottery, are present in archaeosediment layers, the combination of TL ages from pottery and OSL ages from sediments can provide complete data about the occupation and evolution of an archaeological setting. In Mesopotamia, tells are mounds formed by the debris of human occupation and the accumulation of muddy sediments mainly due to the decomposition of mud bricks in ancient towns. Many other materials such as pottery fragments, bones and charcoal can be found in the sediment layers. The combination of OSL, TL and radiocarbon ages can be very useful in the case of the Bronze Age Period in Syria, allowing the occupation sequence of such archaeological sites to be reconstructed. Tell Qubr Abu al-’Atiq, is located on the left bank of the Middle Euphrates River (Syria). The archaeological artefacts found in the sediment layers (pottery) collected during excavations in two areas of the site, indicated the occupation of the tell during the Early and Late Bronze Age by typological pottery classification. The radiocarbon ages of charcoal indicate that human occupation fits the archaeological hypothesis, providing an older and maximum occupation period between 2800 and 2300 BC and a younger period between 1400 and 900 BC. OSL dating of sediments shows ages younger than charcoal, while TL ages of pottery are generally older than sediment and charcoal ages. This can be explained as the different materials correspond to different events. The charcoal and pottery correspond to occupation periods, while sediments correspond to the further destruction of the site.  相似文献
