Ochres have played an important role in early human societies, and recent studies have shown that these pigments are important tools in establishing trade routes between countries as particular varieties of the material were sought for use by these ancient groups. This paper explores the provenancing of the ancient ochres used during the Neolithic Temple Period on the Maltese islands. Here ICP-AES was employed to establish geochemical trends and ‘signature’ elements present in ochre that had previously been thought to have been imported from mainland Europe. When coupled with statistical tests, data was used to link the archaeological pigments to a geological source. Results revealed a strong link between the Maltese archaeological pigments and local sources, which had never been studied prior to this project. These indicated that, contrary to popular belief, the Maltese archipelago was the most likely source for Neolithic ochre. 相似文献

Quilty, P.G., Clark, N. & Hibberd, T., 21.01.2015. Crenostrea sp. cf. C. cannoni (Marwick, 1928) (Bivalvia: Ostreacea) and associated fauna from east of Heard Island, Kerguelen Plateau: age and palaeoenvironmental value. Alcheringa 39, xxx–xxx. ISSN 0311-5518A well-preserved single left valve of a large oyster embedded in coarse volcaniclastic sediment and identified as Crenostrea sp. cf. C. cannoni (Marwick, 1928) was dredged from east of Heard Island, central southern Indian Ocean. It is accompanied by a fragment of the pectinid bivalve Austrochlamys sp. indet. and foraminifera. Austrochlamys sp. indet. and other bivalve fragments were analysed for 87Sr/86Sr, δ18O and δ13C, the results yielding an age of 17.5 Ma (later early Miocene) and a water temperature of ca 10°C. Foraminifera and sediment characteristics indicate that accumulation occurred in mid-continental shelf depths, at a location where nutrient supply was good.Patrick G.

This article aims to highlight and, whenever possible, demonstrate that the urban general plan is still the instrument of the utmost importance to trigger and steer urban transformations. Within the current Italian context, the article examines the characteristics, contradictions, weaknesses and opportunities of urban planning set of rules and practices and tries to propose concrete answers to questions and issues strictly connected that affect the municipality's urban planning: how to manage and govern a contemporary metropolis or city agglomeration, the concerns associated with overlapping jurisdictions and different rules for various hierarchical administrative levels, the costs of social and common services, the need to include in the urban plan the possible use of European Union Structural Funds, the real estate market affecting new development and urban regeneration programmes and investments. All these aspects should be included in a unifying and strong planning instrument, the urban plan, which could address and steer effectively the urban planning policies and their governance. 相似文献

In order to promote “cohesion, competitiveness and cooperation” across Europe, the EU has established a common regional policy to support underdeveloped territories. This EU regional policy required to set up a very complex mechanism to implement such a huge effort to coordinate many interventions across highly differentiated territories. However, those territories are provided with very different institutional settings, and then the mechanism to coordinate all of them becomes particularly complex. The aim of this paper is to discuss the EU multi-level governance for structural funds (SFs), revising the origin, rationale and evolution of this policy in order to identify the limits of the institutional mechanism for the implementation of this policy. These limits will show their effects on the unstable distribution of SFs across the EU regions on a long-term perspective. Results show that the intervention of the EU is neither constant nor stable across regions, independently from their development paths. This instability should provide further arguments on the discussion about the SF policy and governance in order to take into considerations also institutional limits of the EU. 相似文献

Children's independent mobility and physical activity levels are declining in Western countries. In the past 20 years New Zealand children's active travel (walking and cycling) has dropped on average from 130 to 72 minutes per week, and those travelling by car to school have increased from 31% to 58%. This paper describes parents' understandings of why 9–11-year-old primary school children in suburban Auckland are less likely to walk to school and play unsupervised outdoors than they were as children. Data gathered in focus groups show understandings range from proximate neighbourhood explanations to downstream impacts of a neoliberal policy context. 相似文献

Geography, Space, and Science: Perspectives from Studies of Migration and Geographical Sorting 总被引:1,自引:0,他引:1
William A. V. Clark 《Geographical analysis》2008,40(3):258-275
For the past four decades a significant subset of geographers have had a strong interest in using scientific methods and tools to answer questions about society and societal change. The scientific endeavor, learning and verifying new knowledge, has been at the heart of this project. Even though the discipline as a whole seems currently less interested in the classic science project, that project continues within geography and is a part of the wider social science community's attempt to provide verifiable and useful knowledge to a wide range of stakeholders. The findings from studies of migration and the life course, and segregation and geographical sorting reemphasize the very real contribution of spatial science to understanding societal change. Recent work on the geography of neighborhoods and mobility with the context of legal contestation goes beyond academic research per se to show the continuing relevance of an informed scientific approach and the contributions of geography beyond narrow disciplinary boundaries. 相似文献
