The basic monocentric city model implies a decreasing relationship between distance to the Central Business District and outcome variables such as population density, housing prices, land rent, and income. Implicitly, the monocentric model implies directional homogeneity, that is, the distance effect does not depend on the direction in which it is being measured. Only a few works have analyzed the problem of directional heterogeneity. A new conditional parametric approach is introduced to deal with the issue. We study how this approach performs under different spatial patterns comparing with several other methods. An application to the spatial distribution of wage income in the municipality of Madrid is carried out to illustrate the main characteristics of the method and to show the comparative advantages.  相似文献

Shortly after the First World War ended, Australian authorities erected memorials in France and Belgium in memory of the Australian Imperial Force. Decades later, during the so-called ‘second generation of memory’, Australians again engaged in planting memorials on sites of memory on the Western Front. This article compares the two periods of memorial building, contrasting the sites that were chosen for commemoration and examining what these suggest about the difference between past and contemporary modes of remembering the First World War. It highlights the growing importance, in extra-territorial commemoration, of memorial diplomacy and the development of a shared memory between Australians and the communities which host their memorials.  相似文献

The I-district effect hypothesis establishes the existence of highly intense innovation in Marshallian industrial districts due to the presence of external localization economies. However, industrial districts are characterized by specific manufacturing specializations in such a way that this effect could be due to these dominant specializations. The objective of this research is to test whether the effect is explained by the conditions of the territory or by the industrial specialization and to provide additional evidence of the existence and causes of the highly intense innovation in industrial districts (I-district effect). The estimates for Spain of a fixed-effects model interacting territory and industry suggest that the high innovative performance of industrial districts is maintained across sectors, whereas the industrial specialization behaves differently depending on the type of the local production system in which it is placed. The I-district effect is related to the conditions of the territory more than to the industrial specialization. The territory is a key variable in explaining the processes of innovation and should be considered a basic dimension in the design of innovation and industrial policies.  相似文献

Using instrumental neutron activation analysis (INAA) of prehistoric pottery, daub, and modern clay samples from Valencia, Spain, we tested expectations on changes in raw material use with socio-economic shifts during the Neolithic (ca. 5600–2800 BC). Elemental analysis identified three distinctive clay source groups used by Neolithic potters. Contrary to expectations, a shift in raw material use was identified between the Early and Middle Neolithic despite general similarities in technological practices. In the Late Neolithic, pottery production became more specialized, but potters used the same range of clay sources documented earlier. This study illustrates the utility of INAA for testing hypotheses of prehistoric craft production.  相似文献

The diverse cultural spaces of eThekwini (Durban), South Africa, reflect the accommodations and daily cultural negotiations made by the residents of a city whose demographies represent the complex inheritances of interactions between a long history of colonial segregation, nearly 50 years of formal apartheid policies, rapid modernisation, and global networks of migration, production and exchange. This article explores the heavily gendered spaces in which the street food which is characteristic of many areas of the city is produced. ‘Kitchens’, whether a paraffin stove on the street or in an ‘informal’ settlement shack, or dedicated space in a modern flat or house, locate and position borrowings, appropriations and imitations in ingredients, techniques and recipes, between diverse cultural traditions. The cultural performance of identity links the private and the public, the kitchen and the spaces of consumption. Food, and the making of food, are inscribed with ethnicity, with understandings of what is ‘real’, of authenticity and tradition.  相似文献

The region of the Serra de l’Altmirant in southeastern Spain, through its upland location and its rocky and scrub landscape, is strongly perceived as marginal–this mainly in contrast with the nearby fertile coastal plains between Valencia and Denia, busy with orange and vine production especially. A progressive colonization of the lower part of the Serra by weekend homes is starting to counter this image of marginality, but at the same time such constructions threaten the residual archaeology of a different type of human upland exploitation, namely pastoralism and hunting. Abandoned terraces, cisterns, store buildings and larger corrals are evident even on the exposed plateau and testify to a period in which the Serra was active and integral to farmers and shepherds from the villages of the adjoining valleys and plains. This paper discusses the nature of this activity, as recorded through archaeological and ethnographic investigation, and considers also the materials and outlook of Manolo, the last shepherd-in-residence on the Serra.  相似文献
