This paper explores the potential drivers behind uneven regional development in the context of employment growth in Denmark and Sweden. In particular, we are interested in the roles of urbanization, industrial change and the rise of the new economy as manifested in the growth of the two economies in 2002–2007. The aim of this paper is, therefore, to analyse the impact of a number of key industrial sectors on regional employment growth in the two countries. The empirical analysis is based on longitudinal matched employer–employee data retrieved from official registers in each economy from 2002 to 2007, a period of strong national growth following the crisis of early 2000. Our findings indicate that the two economies follow a similar pattern in addressing total employment growth; but looking at changes in employment levels across the national borders of these two relatively similar open economies, we find that, although in general these economies react relatively similarly to changes, embarking on a narrower analysis of the individual sectors reveals marked national differences. This indicates that context matters in the analysis of regional economic dynamics in terms of structure, system and policy.  相似文献

Drawing on recent work highlighting sensory experience of space, this paper argues that understandings of children's and young people's relationships, including difficult family circumstances, may be enriched by taking greater account of their embodied, sensory experience of the domestic spaces in which these relationships are lived. In a study of young people's family life in the context of parental substance misuse, we found that respondents often made sense of difficult family relationships, at different times and in particular spaces, through sensory experience. They also employed sensory and spatial strategies to construct safe and secure domestic places for themselves.  相似文献

Monitoring of the archaeological deposits at the World Heritage Site Bryggen in Bergen has been ongoing since 2001. In latter years a large-scale project of mitigation works has been carried out, resulting in the creation of a water-management system aimed at raising groundwater-levels and increasing soil moisture content in areas with poor preservation conditions. Oxygen is a key parameter in the decay of archaeological material in the unsaturated zone, and the monitoring at Bryggen includes in situ monitoring of oxygen concentrations and comparison to soil moisture content, temperature, groundwater-level, precipitation and soil reactivity. This is used to document where and when decay takes place and to estimate “how wet is wet enough” in order to reduce the oxygen diffusion and the decay rate to an acceptable level. The results show that even small changes in the soil moisture can have a large impact on the oxygen dynamics in the ground.  相似文献

A scalenohedral hematite pendant (presumably a pseudomorph after a calcite crystal), excavated on Bahrain (ancient Dilmun) in the Persian Gulf from layers dated to c.1800 bc , was investigated using X‐ray computed microtomography. The internal porosity was studied in 3D, showing a preferential concentration of small pores in the central part, where carbonate remnants might still be present, and larger, flattened, elongated voids in the subsurface portion. Part of the scalenohedron can be described as an intergrowth of platy hematite crystals. Microtomography also yielded data on pore‐size distribution. Considerations are given to the genetic model and the provenance of the hematite pendant.  相似文献

The EU Water Framework Directive (WFD) can be seen as a reform effort that intervenes in the member states' domestic administrative system by obliging “whole of government” measures across sectoral lines of authority and levels of government. This puts pressure on the sectoral authorities to coordinate their activities. In this article we ask the following questions: How do the state executives respond to the WFD? How can we understand their behaviour and action choices in the implementation of EU law? And third: What can our findings tell us about changes to the European administrative system? This article reveals that despite resistance and strong cognitive priors among the state executives, the WFD logic of ecosystem-based management is gaining a foothold as an administrative principle. Thus, in order to explain changes in the administrative system, we need to take the regional level into account. Our findings suggest that attention needs to be paid to the role of complex, multi-level structures, which includes the regional, river basin district level in the development of a European administrative order.  相似文献

Bjørn Myhre played a key role in the establishment of Norwegian Archaeological Review. All in all, 17 volumes of NAR were produced under his editorial leadership (1968–1978 and 1985–1990). Bjørn Myhre was born in Stavanger in 1938. He did his degree at the University of Bergen (1964), and has since been engaged in research, editing, culture heritage management, excavations, teaching and administration – in Stavanger, Bergen and Oslo. He has produced important prehistoric overviews, cf. Magnus & Myhre 1976, Myhre 2002a, 2003, and 2004. The Iron Age society in south‐west Norway has been central in his research. Of several important excavations, the Iron Age farm site Ullandhaug (1967–68) is fundamental. He has explored different aspects of Iron Age farms – agrarian development, settlement history, house construction and structure (e.g. Myhre 1973, 1978). His studies include discussions on social and political development (Myhre 1985a, 1987, 1998, 2002b). Methodology and theory became a focal point during his time as professor at the University of Oslo from 1985, e.g. ‘Trends in Norwegian archaeology’ (1985b) and ‘Theory in Scandinavian archaeology since 1960 (1991). In 1993, he was appointed as Director of Museum of Archaeology in Stavanger. In 2008 he formally retired, but is still a very active debating and writing archaeologist.

Initially, Bjørn Myhre was invited to write an article about the establishment and first developments of NAR. Subsequently, this was changed to a dialogue text based on questions and answers communicated by email during the autumn of 2007. The basis for questions and replies is a selection of diagrams prepared for the Editorial in this issue which display trends covered in the 40 volumes of NAR.  相似文献
