What do you do if a professional collector starts fossicking in your favourite quarry? Call the police? English Nature? The local museum? Or perhaps nip round with the cheque book to get that crinoid you always wanted for the study wall? The correct answer could be any or all of these; professional fossil collecting is an activity with very real costs which are often outweighed by the benefits. It depends who's collecting what, where and when. 相似文献

There is currently an expansion of local energy initiatives, underpinned by the desire to reduce energy-related carbon emissions and in recognition of the importance of the local arena to achieving such change. Much of the research on these initiatives has been framed by a conventional economic approach, identifying barriers, drivers and incentives to explain their emergence (or not). Here a new economic sociological approach is taken which sees markets as socio-materially constructed and points to the importance of tracing exchange flows and determining modalities of valuation for such exchanges. Artefacts or market devices are seen to play a particular role in connecting actors and technologies within coordinating institutional arrangements and offer the potential for making innovative projects conventional. These aspects are explored in four international case-studies from Wales, Sweden, Germany and USA, mapping relations, identifying exchange flows, pinpointing how artefacts coordinate and showing the multiple modalities of valuation involved in each case. Conclusions concerning the importance of negotiation against a market backdrop and rendering exchange flows more certain are drawn. 相似文献

The university as a local source of expertise 总被引：4，自引：0，他引：4

The relationship between the university and the city is expressed, amongst others, by the transfer of knowledge from the university to local actors. The universitys role as a local source of knowledge is studied by analyzing the outflow of the two main knowledge assets to the local area: graduates and research results. By comparing the results from universities in the Netherlands and the United Kingdom comparative evidence is discussed. 相似文献

The local geographies of poverty: a rural case-study 总被引：1，自引：0，他引：1
Paul Milbourne 《Geoforum》2004,35(5):559-575
Recent years have witnessed a renewed interest in the spaces of poverty in Britain. An increasing number of geographers have placed poverty back `on the map' by pointing to its complex spatial manifestations. In addition, the increased importance attached to the concept of social exclusion within UK social welfare discourse has led to social policy researchers thinking more critically about the broader social and spatial contexts of poverty and, consequently, new connections between poverty and space have been identified. However, within these new spatialised accounts of poverty in Britain, scant attention has been given to the local geographies of poverty. In fact, relatively little is known about the complex connections between poverty and place, and, more specifically, the ways that poverty is associated with different material forms, representations and experiences in particular local contexts. This paper develops these kinds of connection between poverty and place through an exploration of the local geographies of rural poverty in South-west England. Based on an analysis of local poverty data, in-depth interviews with a broad range of key agencies and a case-study of poverty in a particular village, the research highlights the complex socio-spatial nature of poverty, the different spatial scales and visibilities of poverty, and important connections between poverty and the shifting social composition of local space. 相似文献

It is shown that the random-motion theorem in cosmology proven in the early 1960s can be generalized to take into account
the presence of a uniform dark-energy background. The role of the dark energy is substantial: its repulsive force exceeds
the gravitational force due to darkmatter and baryons, both on the scale of the Universe as a whole and on local scales of
about 1 Mpc. The generalized random-motion theorem has the form of a differential equation relating the kinetic energy of
the random motion and the potential energy of the particles due to their own gravitational field and the repulsive dark-energy
field. One consequence of the generalized theorem is a virial relation containing the potential energy in the repulsive field. 相似文献

The Nurek Reservoir is located in an area of high seismicity. An average of 5–6 earthquakes of (Russian energy class)K = 10 and 1–2 earthquakes ofK = 11 per year occurred in the vicinity of the reservoir. The largest local earthquake recorded fell in the energy classK = 14 (1956).
At the end of 1972, after the water level had risen to 100 m, earthquake activity increased sharply. Three events ofK = 12 were recorded during one month and the total number of earthquakes (K 7) exceeded three times the former mean level of seismicity.
Spatial and temporal properties in the epicentral distribution showed a migration from the southwest toward the reservoir.
Earthquake mechanisms of 215 events ofK 9 since 1960 were analysed. Fault plane solutions for some of the earthquakes which occurred after the impoundment were found to be different from the ordinary ones. 相似文献

The objective in this paper is to analyse private sector involvement in LED in South Africa. Four key spheres of private sector involvement in LED are identified and discussed: (1) as participator and occasional initiator of local development processes, (2) as major partner in the development activities of public-private sector partnerships, (3) as lead role player in certain direct initiatives for reviving South Africa's inner cities, and (4) as promoter and facilitator of local small business development. It is argued that the concept of local dependence could be usefully applied to interpret private sector involvement in LED in South Africa. 相似文献
