Recent studies have shown that pre-Columbian societies in the Amazon undertook significant landscape modifications, including earthworks. Our fieldwork has revealed that pre-Columbian settlements in the Santarém Region, Lower Amazon, were not limited to the vicinities of permanent water courses, as formerly often assumed. Instead, numerous archaeological sites, dating from ca. a.d. 1300 up to the time of European colonization in the seventeenth century, have been found in an upland area known as the Belterra Plateau, south of the present-day city of Santarém. These upland sites have been found to be associated with particular features in the landscape: cavities or depressions, known locally as “Poços de Água”. LiDAR data shows that a pattern of non-randomly distributed depressions extends far into the densely forested Tapajós National Forest (Flona-Tapajós), allowing us to suggest that the expansion of inland settlement extended considerably farther to the south than what has previously been established through conventional archaeological fieldwork.  相似文献

This paper aims at a greater comprehension of the distribution of differentiated knowledge bases and their association with innovation performance. Drawing on evolutionary economic geography, we applied a combinatorial and dynamic view on knowledge bases. The main contribution is the examination of changes and transformations of knowledge bases over time in particular group of regions in Europe and links with innovation performance. Our study revealed systematic regularities between regions with different innovation performance and their knowledge bases. With decreasing regional innovation performance the volatility of knowledge bases over time increases. Innovation leaders evinced stability over time and the most balanced composition of knowledge bases (compared with Central and Eastern Europe regions). Western European countries and regions exhibit the most balanced structure of knowledge bases. An important complementarity and synergy has been identified in the close relatedness of the symbolic knowledge base to the analytical knowledge base. The highest intensity of SME cooperation takes place in regions with a strong analytical base and in regions with the most balanced mix among all three bases (particularly in the UK, the Netherlands and Belgium. Underperforming in innovation show a balanced mix of synthetic and symbolic knowledge bases.  相似文献

In this paper, we argue that place mapping is useful for approaching children's conception of place and that this is of relevance when designing physical activity interventions. We contend that socio-material factors influence children's perception and use of places, and are crucial to understand in relation to their use of local neighbourhoods for physical activity. A place mapping of children's understandings and everyday use of their local neighbourhood in suburban Copenhagen was conducted with a fifth grade elementary school class. The mapping and subsequent analysis resulted in three categories of relevance to children's conceptions of place; located social experiences, experiences of the unknown, and children's contested spaces. We argue that such knowledge can provide useful information in the development and evaluation of activities that promote physical activity in urban spaces.  相似文献

Abstract

An essential feature associated with the rise of the knowledge economy has been the increasing focus on the importance of human capital as a precondition for economic growth. Human capital has been found to have a positive impact on the economic growth of high-tech industries, however, the influence of human capital on the development of low-tech industries is yet to be analysed. This paper provides such an examination of low-tech industries based on an analysis of employment data within manufacturing industries in Denmark in the period 1993–2006. The findings highlight, first, that human capital appears to be equally important for economic development in low-tech industries and, second, that the divide between the large urban regions, especially Copenhagen, and the rest of the country plays the primary role in explaining the geography of human capital. These findings stress the relevance of a broad conception of the knowledge economy which goes beyond high-tech industries.  相似文献

Several studies have shown dense urban structures to be favourable in order to reduce greenhouse gas emissions from transport, limit energy consumption in buildings and protect farmland and natural areas in the surroundings of the city. There may, however, be some tensions between such a compact urban developmental strategy and considerations of public health in urban planning. This paper reviews findings from international research on the relationships between urban form and health and illustrates some of these effects by comparing statistics on life expectancy and the frequency of heart attacks among inhabitants of different urban districts in the Norwegian capital Oslo. Since we have only had access to aggregate figures at the level of urban districts, the results must be interpreted with caution. The currently available results do, however, suggest that the densification strategies often recommended for reducing the ecological footprints of cities might be encumbered with some important drawbacks, seen from a public health perspective. Based on the findings, some dilemmas and perspectives for sustainability- and health-oriented urban planning are discussed.  相似文献

Some firms within the conventional agri-food processing industry change their business strategy by trying to innovate towards alternative foods, like regional foods. For firms which are part of a larger organization or integrated in a group of companies this is a special challenge. The purpose of this paper is to explore what happens when a firm within a large and complex organization tries to turn from a productivist strategy to a differentiated strategy. This exploration uses a case study from the Norwegian dairy industry. The case shows that powerful industrial conventions and lack of suitable organizational conditions can be a hindrance for organizational change. Organizational capabilities to change routines and conventions have significant influence on the result of the innovation process.  相似文献
