In recent years the urban question in the European Union has been a matter of deep focus and intensive debate, contributing to the European Community environmental, spatial and sustainability policies approach, however not entirely reflected in the current version of the 6th European Environmental Action Programme. The POLIS programme, initiated in Portugal at the time of the last Portuguese Presidency of the European Union (January–June 2000), illustrates the Portuguese urban environmental policy approach in that period, in response to contemporary trends and priorities regarding the improvement of urban life and governance. This article describes the POLIS programme, its current status and how it meets current challenges. The expetience acquired so far with the POLIS programme may be useful in the broader context of the discussion of an European urban policy. 相似文献

Network interaction is embedded in social settings, which allows for the development of trust. Trust is supposed to be an efficient functional equivalent of contracts, guarantees, insurances, safeguards, etc. Trust between actors reduces transaction costs. However, trust cannot be introduced and enforced within interaction relationships. It is argued that trust is more likely to occur and to be prevalent when actors have the spatial capability for personal, direct interaction. Thus, proximity and trust are supposed to be positively related to each other. Proximity is strongly interrelated with embeddedness. In the discussion about morality in organisations, there is an assumption we referred to as the 'moral spill-over effect': it is impossible, it is said, to restrict moral competencies and moral behaviour to one particular situation, environment, or topic. However, we argue that, even though trust is a term that is described in moral theory, trust and morality are not necessarily positively correlated. This means that even if embeddedness and proximity in a network lead to an increase of trust between network partners, it does not necessarily produce moral spill-over effects. Thus, proximity and morality do not necessarily have to be positively correlated with each other. The influence of proximity on morality can be positive or negative, depending on the social surrounding in which network collaboration is embedded. 相似文献

Professional visual artists have always enjoyed considerable latitude in the selection of a place of work and residence. Recent decades have witnessed their growing presence within the Canadian countryside. This paper seeks to provide an interpretation of this phenomenon by exploring two sub-objectives. First is to determine whether artists who establish themselves in rural communities can be considered to be part of the counter‐urbanisation movement, involving the relocation of urban residents down the settlement hierarchy. Second is to identify what types of migration are occurring and why. Our surveys of visual artists residing in the southern Ontario communities of Elora and Parry Sound reveal that most participants are part of a movement involving the decision to take up both residence and employment in a rural locale. We further find that the relocation of visual artists is driven to some extent by a strong attachment to natural landscapes. By way of conclusions, we briefly speculate about the broader population of urban residents. We remind ourselves that artists often have been harbingers of new movements and that today there are growing numbers of workers outside the artistic community who also have increasing latitude in regards to choosing where to live and work. Overall, our findings suggest that there is ongoing blurring of geographic boundaries—between space and place, between place of work and place of residence and, of course, between rural and urban. 相似文献

During the nineteenth century, the existence of a southern border in the Córdoba province resulted from a complex situation
where an expanding national state was inserted into a global economic system and into an environment occupied by various Indian
groups. This situation created a mixed society on the borderlands. The military line was defended by forts, with one of them
being the Achiras Fort (1832–1869). The fort was situated at the end of the mountain range of Comechingones. This paper considers
the archaeological investigation of this fort. The most important and consistent part of the archaeological record is the
Command. The Command was formed by two rooms. This work also presents the results of the excavations into the fort and describes
the archaeological remains found. Finally, a general model for archaeology in the South Córdoba Border is presented. 相似文献

The presence of many phytolith-rich layers in late Bronze and Iron Age deposits at Tel Dor, Israel, are indicative of specific locations where plants were concentrated. Detailed studies of six of these phytolith-rich layers and associated sediments from Tel Dor show that the phytoliths were derived mainly from wild and domestic grasses. The most common domestic grass was the cereal Triticum aestivum (bread wheat). Three of these layers have a microlaminated microstructure, associated dung spherulites and phosphate nodules; characteristics that all point to the phytolith-rich layers having formed from dung in animal enclosures. In two of the layers, the microlaminated structure is absent while dung spherulites and phosphate nodules are present, suggesting that these too originate from dung that was not deposited in an enclosure. The sixth layer is microlaminated but does not contain spherulites. We thus cannot suggest a parsimonious explanation of its observed properties. Concentrations of burnt phytoliths are present in three locations, implying that dung was either burnt in situ or the ashes from burnt dung were redeposited. The transformation of dung accumulations into phytolith-rich layers involves a loss of organic material and hence a significant reduction in sediment volume, which is clearly apparent in the stratigraphy of some of the locations examined. The volume reduction can be observed in the macrostratigraphy and has important implications with regard to macrostratigraphic interpretation. The presence of abundant phytolith-rich layers on the tell has significant implications for the concept of ‘urbanism’ during these periods. 相似文献

Plant exploitation and ethnopalynological evidence from the Wadi Teshuinat area (Tadrart Acacus,Libyan Sahara) 总被引:1,自引:0,他引:1
Pollen analyses of 13 archaeological sites in the Wadi Teshuinat area, in southwestern Fezzan, Libya, were synthesised to explore the potential contribution of palynological investigation to archaeological research in this area. During the Holocene, the sites were occupied by pre-Pastoral (hunter–gatherers) and Pastoral (pastoralists) cultures. Different pollen stratigraphies and floras characterised the diverse sites and the relevant cultural phases. Pollen data were reported by discussing the sites separately, and by combining them to interpret the regional data set. Emphasis was made on the anthropogenic pollen indicators and grasses, including large grass pollen grains (>40 μm), which were considered evidence of plant transport into the site. These were ethnobotanical markers, human-made evidence of plant harvesting by hunter–gatherers, or of animal breeding by pastoralists. The disappearance of some wild cereals was also observed, consistent with increasing climate dryness and land exploitation. Macroremains were used as a parallel tool to better understand plant exploitation in the region. 相似文献

It is of vital importance to be able to sex identify cattle remains to understand the strategies and importance of cattle husbandry in an ancient society. This is usually done from osteoarchaeological assemblages and often relies on measurements of metapodials. The breadth measurement of the distal trochlea is considered an easy way to identify the sex. Bones from males appears to be easily distinguishable from female counterparts, although it has been complicated to find an external control for the morphological results. Here we investigate the reliability of these particular morphometrics for sex identifying cattle bones with molecular genetics. We use a sex discriminating single nucleotide polymorphism in the ZFXY gene and we apply it to DNA from the bones. To keep the fragment size short and suitable for ancient DNA we base the test on a SNP. The test confirms the osteological sex identification in all cases were DNA could be retrieved. This molecular method can also be used when no fragments suitable for osteological sex identification can be found or when the measurements are non-conclusive. 相似文献
