Deploying an everyday life approach, this article focuses on the kindergarten meal, defined as a space in which humans, materials and discursive elements interact. The article identifies and discusses two co-existing perspectives on the everyday meals that emphasise children as future beings and here-and-now beings. Through the concepts of smoothing and striation the paper discusses how these perspectives produce different mechanisms of regulation and agency, and position the eaters differently. The paper emphasises kindergarten mealtime as an ambiguous space that does not offer simple discussions about good and bad meal situations. The paper thereby adds to the existing literature within children’s geographies which emphasise interactional, relational and material aspects of children’s lives. It does so by revisiting some concepts, striation and smoothing, that has been used to explore children’s spaces and child–adult relations, but argue that these concepts describe ambivalent and complex processes in children’s and adult’s everyday lives.  相似文献

Archaeological evidence for coastal shellfish exploitation in Arctic Norway mostly dates from 5300 to 1500 BC, encompassing the terminal Mesolithic, the Late Stone Age, and the beginning of the Early Metal Period. Shell middens are generally associated with semi-subterranean houses, but may also occur as free-standing deposits. The primary shellfish taxa exploited were Littorina littorea, Arctica islandica and Mytilus edulis. Most of the species utilized were available in the littoral zone and were easily procured in the course of daily household activities, but sub-littoral A. islandica would have required greater investment in procurement technology and time, as well as labor cooperation. Shellfish were an occasional dietary supplement and could also serve as fishing bait. Spatial and temporal variation in shellfish assemblages reflects local marine ecology, sea-level changes, household dynamics, and perhaps field processing. Interpretation of the existing data is constrained by inadequate midden sampling and documentation methods.  相似文献

Public funding is crucial for the small Norwegian film industry. Based on an analysis of policy documents and interviews with regional film workers, this article discusses the implementation of regional film policy in Norway, and the tensions it has caused between center and periphery with respect to the allocation of funding. The creative industries discourse and the cluster concept are important for understanding this implementation; despite the new regional film policies the capital Oslo remains the undisputed hub of film production, and low production volume is still a challenge for the regions. Size, the article explains, is not only central when discussing Oslo as compared to the regions, but has also become a contentious issue within the regions. A key concern for the government, the article suggests, is how to create strong film milieus all over the country, which may entail the risk of spreading funding too thinly across the regions, resulting in a fragmented industry.  相似文献

Many indigenous communities are at a crossroads as regards lived experience of traditional livelihoods and members with intimate knowledge of their traditional landscapes. Using case studies from two indigenous communities, this article explores the application of both GIS tools and other geographic multimedia in community-based research projects that document landscape-related knowledge. The study involves a First Nation community in British Columbia, Canada and a Sámi community in Finnmark County, Norway. We discuss how land-use traditions and related knowledge constitute a peoples' identity and explore digital means of transferring this knowledge to support the ongoing transfer of indigenous knowledge between geographically dispersed community members, as well as future generations.  相似文献

ABSTRACT

This paper contributes to the literature on urban climate change experiments by analysing ascribed advantages and challenges of organizing climate change experiments at the urban scale, and by examining how local actions translate into effect. We here distinguish between effects of experiments in achieving actual sustainability gains (‘goal-oriented objectives’) and instigating broader institutional change (‘process-oriented objectives’). Empirically, we analyse efforts related to energy supply in two Danish urban climate change experiments: The ‘CPH 2025 Climate Plan’ in Copenhagen, and ‘ProjectZero’ in Sønderborg. Our analysis poses considerable question marks over the importance of the advantages ascribed to urban climate change experiments including ‘authority advantages’ and possibilities of ‘engaging and mobilizing stakeholders’.  相似文献

Results from surface geochemical prospecting, seismic exploration and satellite remote sensing have documented oil and gas seeps in marine basins around the world. Seeps are a dynamic component of the carbon cycle and can be important indicators for economically significant hydrocarbon deposits. The northern Gulf of Mexico contains hundreds of active seeps that can be studied experimentally with the use of submarines and Remotely Operated Vehicles (ROV). Hydrocarbon flux through surface sediments profoundly alters benthic ecology and seafloor geology at seeps. In water depths of 500–2000 m, rapid gas flux results in shallow, metastable deposits of gas hydrate, which reduce sediment porosity and affect seepage rates. This paper details the processes that occur during the final, brief transition — as oil and gas escape from the seafloor, rise through the water and dissolve, are consumed by microbial processes, or disperse into the atmosphere. The geology of the upper sediment column determines whether discharge is rapid and episodic, as occurs in mud volcanoes, or more gradual and steady, as occurs where the seep orifice is plugged with gas hydrate. In both cases, seep oil and gas appear to rise through the water in close proximity instead of separating. Chemical alteration of the oil is relatively minor during transit through the water column, but once at the sea surface its more volatile components rapidly evaporate. Gas bubbles rapidly dissolve as they rise, although observations suggest that oil coatings on the bubbles inhibit dissolution. At the sea surface, the floating oil forms slicks, detectable by remote sensing, whose origins are laterally within ~1000 m of the seafloor vent. This contradicts the much larger distance predicted if oil drops rise through a 500 m water column at an expected rate of ~0.01 m s?1 while subjected to lateral currents of ~0.2 m s?1 or greater. It indicates that oil rises with the gas bubbles at speeds of ~0.15 m s?1 all the way to the surface.  相似文献
