In the study area (the Upper Rhine Lowlands and the southern Black Forest), colluvial and alluvial sediments could be dated with the aid of 14C analysis, archaeological finds, pollen analysis and stratigraphic assessments. On the basis of these dated deposits, six different maps have been produced showing the distribution of the colluvial and alluvial sediments for the corresponding archaeological cultural periods. For each of these periods, the intensity of human impact on the environment has been estimated in relation to climatic conditions and different economic activities; for example, woodland clearance and mining activities. 相似文献

The theory of the marginal consumer holds that a subset of better informed consumers can create a globally more efficient market through their purchase decisions. In the market for education created by recent school choice initiatives, these "market mavens" are essential to the successful functioning of the choice system given the empirically documented low quantity and quality of information possessed by the average consumer. Little is known, however, about the differences between how marginal consumers and average consumers of education search for information and make decisions about their children's schooling. 相似文献

The intersections between the concepts of space, place and resistance have recently received increasing attention from geographers dedicated to the study of social movements. Space and place are not merely seen as providing a physical background for mobilisations but as mutually constitutive of social movement agency. Yet, critics of theoretical frameworks drawn up by geographers have often rightly pointed to the lack of convincing empirical evidence presented in their support.This paper addresses these critiques by offering a theoretically informed and empirically grounded account of recent mobilisations by the social movement of black communities in the Pacific coast region of Colombia. Drawing on both the objective aspects of place and the subjective feelings that are derived from living in a place, I will show how these mechanisms have impacted on the specific spatial organising forms adopted by black communities. In particular, I will propose the concept of ‘aquatic space’ as a set of spatialised social relationships among Afro-Colombians, and show how these concrete everyday geographies have been drawn upon by black communities in the establishment of community councils along river basins.The paper argues that to make a strong point for more spatially sensitive analyses of social movements, geographers have to sustain their theoretical frameworks with concrete empirical data that not only illustrate spatial processes at play, but also convincingly demonstrate their very embeddedness in social practice. I thus argue for a strong consideration of ethnographies as a privileged research methodology to flesh out the geographies of social movements. 相似文献

National Socialism brought about profound changes for the German academic system. Forced emigration not just sent outstanding scholars into exile, thus closing down promising research venues. In fact, it changed the entire climate of scientific inquiry by removing intellectual outsiders from the scene, whose absence usually precludes any success of innovative research. In most disciplines this led to a dominance of just a few academic ‘schools’ and paradigms, which severely harmed intra‐discipline accountability and innovation. The academic bureaucracy worked more effectively than has been assumed for a long time: practice‐oriented research enjoyed massive state support, and huge research projects outside the universities flourished. At the same time the National Socialists looked ambivalently at the universities themselves. They savored the legitimizing functions of the arts and sciences, and yet they distrusted the professors as exponents of the bourgeois world of old. Contrary to the blooming sciences such as biology, chemistry, and physics, the arts and humanities had a hard time demonstrating their practical applicability. In order to prove their worth by means of giving advice to the political sphere, they formed interdisciplinary combines, which were massively funded by the ‘Deutsche Forschungsgemeinschaft’. The ‘Deutsche Wissenschaft’, which has been incorrectly marginalized in numerous accounts, served in part to provide a Weltanschauung justification for these networks. While the German academic community in 1945 tried to pick up the threads of the a‐political self‐ understanding of the 1920s, in fact there were numerous continuities to academic life before and after 1945. Among them were the encompassing loss of international contacts, the strengthening of hierarchical structures, and the importance of feasibility criteria for the culture of innovation. The arts and humanities (Geisteswissenschaften) could not regain the lost territory of significance, which they had suffered during the Third Reich. It is mainly their development which showed an amazing persistence of national socialist patterns of view and of concepts of the enemy, which in turn as late as 1968 inspired in part the anti‐bourgeois thrust of the critique of the academic world. 相似文献
