ABSTRACT

This article centres on the introduction of the French 75mm light field gun, and its impact on the European military balance in the two decades before the First World War. It argues that the 75mm (and particularly its new recoil-absorption mechanism) dramatically accelerated the rate of fire and gave France a major military advantage over Germany between c. 1899 and 1906. Subsequently the application of the new technology to howitzers and heavy artillery enabled Germany to redress the balance. On the eve of war, however, Germany's leaders feared a new round of French and Russian emulation, and this fear influenced their policy in the July 1914 crisis. The article also examines the failure to forestall the quick-firing revolution at the First Hague Peace Conference; the new technology's role in the First Moroccan Crisis; its dissemination across Europe and the Franco-German competition to amass reserves of shells.  相似文献

The European Spatial Development Perspective (ESDP) is the product of a north‐west European planning tradition. This article discusses the role of north‐west European concerns, in particular the use of the concept of polycentricity, in the making of the ESDP, and the application of the ESDP in the North‐west European Metropolitan Area (NWMA), more in particular in Germany, the UK, The Netherlands and Belgium. The article also explores the future of spatial planning as regards north‐west Europe. Much will depend on how Community policy will adapt to the enlargement of the European Union. However, it seems certain that existing member states, in particular those in north‐west Europe will see their share in the structural funds evaporate. This may give added significance to INTERREG IIIB respectively to the successor of this Community Initiative. In addition, concepts like territorial cohesion and territorial management may become functional equivalents to that of spatial planning, for which the Community is said to have no competence.  相似文献

Abstract

This article examines the opinions, arguments and actions which led to the foundation of universities in the North: in alphabetical order, Leeds, Liverpool, Manchester, Sheffield. Among the topics discussed are: the availability of funding from private sources, the extent of local (especially aristocratic) support, the limited involvement of governments, the differing attitudes towards science and technology, and civic rivalries. Essential features of the ‘university movement’ are displayed, along with the assumptions and ambitions of the Victorians, locally and nationally.  相似文献

Abstract

Semi-arid landscapes are vulnerable to cultivation, overgrazing and climate variability, although it is difficult to identify the relative significance of these three factors. In the South African Karoo, the ‘desertification debate' seeks to explain a change to more shrubby vegetation in heavily grazed areas. We examine these issues in catchments where farm reservoirs provide sediment stores with 137Cs, 210Pb, geochemical and mineral magnetic signatures. Rainfall data and stocking numbers are reported and current erosion rates are estimated. Sediment accumulation in the reservoirs increases between 1935 and 1940, probably due to rises in the frequency of rainfall events of >25mm day. Significant increases in sedimentation rates (×8) occur during rain-fed wheat cultivation. In an uncultivated catchment, sediment yields remain relatively high and reflect increases in erosion from hillslopes, colluvial storage, and cultivated land sources. Gully systems have acted as transport routes rather than sediment sources over the last ~70 years. Badland erosion rates average ca. 50t ha?1 yr?1. At Ganora, their development in the 1920s strongly influences peak sedimentation between 1970 and 1980. Any delay between badland initiation and increased sediment yield appears to be a function of landscape connectivity. Recovery following disturbance is occurring slowly and is likely to take >100 years. De-stocking and better management systems are reducing erosion rates but may be offset by increases in rainfall intensity.  相似文献

The conventional story of suburbanization in Canada and the United States portrays an outward movement of residences from the cities that only since World War II has been fuelled by the dispersal of employment to the urban fringe. This prevailing wisdom needs considerable revision. In this essay we present a theoretical interpretation of industrial suburbanization. We argue that the outward spread of factories and manuÍfacturing districts has been a distinctive and important feature of North American urbanization since the middle of the nineteenth century. The paper begins with a discussion of how industrial decentralization has been repeatedly misinterpreted as new and unprecedented, rather than an extension of past trends. In contrast to the prevailing interpretation, we claim that industrial suburbanization is the product of a combination of the economic logic of geographical industrialization, investment in real estate, and political guidance by business and government leaders. The result has been extensive, multinodal metropolitan regions.  相似文献
