The incentives for large-scale hydropower development in Sweden are usually explained in terms of the early 20th-century belief in progress and the need for energy to fuel industrialization and modernization. For reindeer husbandry, the consequences and cumulative effects of this large-scale landscape conversion, and the societal changes it entailed are still largely a story to be told as impacts and effects constantly evolve in the socio-ecological system of the reindeer grazing lands. The present article 1 1 This article is part of the multi-disciplinary research project ‘Adaptations of Natural Resource-based Communities to Climatic and Societal Changes: Sami Reindeer Herding in the Past, Present and Future’ funded by The Swedish Research Council, FORMAS, The National Space Board and Faculty of Humanities, Umeå University. investigates hydropower development in the northern parts of Sweden, and how the reindeer husbandry of the indigenous Sami people was involved, through a case study of three hydropower projects in the early 20th century. An additional perspective is illuminated: how early hydroelectric development in the reindeer grazing areas was made possible through an immersed colonialism.  相似文献

The present paper investigates the seismic energy demand in steel moment-resisting frames. The frames, with 3, 6 and 10 storeys, and 4 and 8 spans, are designed according to current seismic code provisions. The energy response (energy quantities and their distributions) in the frames subjected to an ensemble of six earthquake ground motions recorded on different soil conditions, is investigated by nonlinear time history analysis. The study concludes that (1) the results of energy response can be developed into a rational method of seismic evaluation and design for steel moment-resisting frames; (2) the energy concept based on the single-degree-of-freedom has limitations when extended to the realistic structural system for design purposes; and (3) it is necessary to develop the energy-based approach for seismic evaluation and design based on the seismic response of a realistic multi-degree-of-freedom structural system.  相似文献

A theoretical attenuation model of earthquake-induced ground motion is presented and discussed. This model is related directly to physical quantities such as source and wave motion parameters. An attenuation formula for rms acceleration of ground motion is derived and verified using acceleration data from moderate-sized earthquakes recorded in Iceland from 1986 to 1997. The source parameters and the crustal attenuation are computed uniformly for the applied earthquake data. Furthermore, attenuation formulas for peak ground acceleration are put forward.  相似文献

Ten geological samples (five from each source—Romanian amber and Baltic amber) in duplicate for five different media (air, water, saline, acid and basic) were subjected to thermal alteration at 80 ± 2°C for 12 weeks, in the dark. The samples were analysed before and after the accelerated alteration experiment by Fourier transform infrared spectroscopy, both in transmittance and reflectance mode, and the acquired spectra were statistically processed by multivariate data analysis, mainly using principal component analysis. The results of the experiment are useful in giving a better picture of how to discriminate between archaeological amber artefacts.  相似文献

Neutron Activation Analysis (NAA) has been carried out in order to determine the provenance of a selected set of 30 sherds of Mycenaean style excavated at Tarsus‐Gözlükule. The provenance could be established or made feasible in 80% of the samples. The results confirm the current status of research, namely that in the LH IIIC phase trade patterns changed and Mycenaean wares, which used to be exported to the Near East, were now produced locally. At Tarsus, the LH IIIC imports came from Cyprus and the eastern Aegean.  相似文献

In a residence environment, housing and housing groups constitute a fundamental life space to meet the needs of the residents, to satisfy them, and to maintain the overall health of individuals and public. Various needs that appear due to the problems caused by housing and residence environment situated in a physical, psychological and socio-cultural environment together with their surroundings affect resident satisfaction and attitude, while directing the overall individual/family and public health, happiness and welfare. Most researchers argue about and try to determine the residents' needs related to their expectations of and satisfaction in housing and residence environment, within the framework of basic needs of human beings. In this study, in order to assess the factors that improve housing and environmental quality satisfaction, the concepts of housing and its environment, and the subject of housing and environmental quality satisfaction have been investigated; the conceptual model of housing and environmental quality satisfaction has been developed, which takes up the subject of user satisfaction in housing and environment quality as a whole; and the factors to increase the level of satisfaction in housing and environmental quality have been specified. A sum of 400 questionnaire inquiries has been made in planned mass housing areas in the Istanbul Metropolitan Area. Applying factor analysis to the data that have been gathered as a result of questionnaire inquiries, the following factors have been determined according to their order of importance to increase the level of user satisfaction in housing and environmental quality. The findings of this study show that, the elements influencing these factor groups include accessibility to various function areas in the inhabited housing area, environmental features of the housing, satisfaction in the various facilities in the inhabited environment, environmental security, neighbour relationships, and the appearance of the housing environment. A logistic regression model has been made to assess whether there are any differences among the factors influencing housing and environmental quality satisfaction for mass housing users on location choice (central districts and peripheral districts) at the metropolitan level.  相似文献

The main aim of this paper is to propose a model for measuring the sustainability level of historic urban quarters and to indicate an appropriate strategy for their revitalization. Based on this aim, this study first presents the theoretical review on the concept of “revitalization”, and its relationship with sustainability; next, it introduces the characteristics, role, selection process and scaling method of sustainability indicators, which are essential for measuring the level of sustainability. The paper then, as the main contribution of this paper, proposes the model for measuring the level of sustainability in historic urban quarters and determines some proposals to achieve revitalized and sustainable historic urban quarters. Depending on the proposed model, there is a direct relationship between type and the level of obsolescence (revitalization) and the level of sustainability in the physical, economic and social structures of a particular area. Therefore, when the level of sustainability is high in any one of these three structures, it means that the level of obsolescence is low in the same structures of an historic urban quarter. The result of this paper leads us to say that, the level of sustainability is a new (additional) input in the strategic planning process of revitalization and sustainable urban revitalization of historic urban quarters. Finally, the paper concludes with a brief summary on the general arguments of the paper.  相似文献

This article investigates the impact of public capital formation on private manufacturing sector performance in the seven geographical regions of Turkey and in aggregate. A vector autoregression (VAR) model has been employed to estimate long run accumulated elasticities of private sector variables with respect to public capital for the time period 1980–2000. The results show that public capital affects private output positively in aggregate and in all regions apart from the Black Sea and Mediterranean regions. The results also reveal that only in the Marmara region, the impact is positive both on input and output. The public capital crowds in private sector inputs in some regions.  相似文献
