Reindeer herding in Scandinavia has in recent years been studied as a common‐pool resource problem. In such studies the size of the herds are often analysed in relation to issues like economics, demography, and technology. In this article the author discusses the size of reindeer herds in relation to social and organisational issues in the light of experiences from an environmental assessment.  相似文献

Weathering forms were encountered during field work in a formerly glaciated shield area in Canada that lies within the Labrador‐Ungava sector of the former Laurentide Ice Sheet. The granite and gneissic granite in the study area display features of surface weathering, such as weathering pits, and of deep weathering, such as an exposed weathering front with associated gravelly saprolite and core stones. Most observations were made along the shoreline of the Caniapiscau reservoir, where wave abrasion since the construction of a hydropower dam has lead to recent exposure of bedrock over extensive areas. The saprolite remnants emphasise the importance of weathering processes in shaping of bedrock relief in the area and together with the other weathering forms indicate restricted glacial erosion. The weathering forms are discussed in the context of glacial erosion and preservation mechanisms.  相似文献

This paper deals with the question of agglomeration of economic of activities and the internet industry in Stockholm, Sweden. The paper discusses the importance of proximity, especially in the knowledge transmission, and uses a theoretical framework of localized and tacit knowledge. The empirical findings suggests that firms within the internet industry are located in close proximity to each other because of the importance of dense informal interpersonal networks, that facilitate the search for new customers and collaborators. The findings also stress the importance of proximity in creating these dense networks and being in the right place at the right time.  相似文献

Recent research by Chinese archaeologists has identified many late prehistoric (2000-400 B.C.) oases, pastoral settlements, and cemeteries in eastern Central Asia (Xinjiang province of China). The synthesis presented here organizes the data into 10 archaeological cultures, defined on the basis of ceramics, burials, small finds, and architecture. The archaeological cultures reveal two periods, corresponding to the Bronze Age and the Iron Age. The oases cultures formed a core area before the Chinese Han period and maintained close contacts with nearby highland pastoralists in Siberia and western Central Asia. The evidence for interaction between Xinjiang and the complex cultures in China and western Central Asia is evaluated with regard to the origins of the early Xinjiang cultures.  相似文献

The Greek-Norwegian Deep-Water Archaeological Survey   总被引:1,自引:0,他引:1  
From 1999 to 2003 the project surveyed the sea-bed in selected areas in Greece in order to locate marine cultural remains in depths below 50 m that have not been explored by divers. The project has shown that it is possible to perform systematic large-area surveys in deeper waters using off-the-shelf equipment from available small ships, at relatively low cost with good results.

Swedish health information, conducted by the National Board of Health and Welfare in collaboration with private participants, expanded rapidly in the 1970s. This study examines a controversial bread campaign, which declared that the National Board, in collaboration with the private Bread Institute, wanted citizens to eat six to eight slices of bread every day. Why and how could such a seemingly unholy alliance come about? Contextualizing the collaborations with the industry, with a network governance approach, this article seeks the answers by investigating the organizational conditions behind the various campaigns. Different conflicting dilemmas influenced the campaigns and their outcomes. For example, the desire to maximize the disseminationof information, and at the same time controlling it, as well as the imbedded power dynamics between private and public sector. The result points to a shift from strong to weak interdependence between the government agency and collaborating parties, basically due to the agency’s diminishing campaign resources, which opened up for a stronger commercialization of the bread campaign.  相似文献
