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

Thomas Wieland's book is the first survey on the history of scientific plant breeding in Germany from 1889 to 1945. There are two mainlines of analysis: (1) The transformation of an agricultural practise of peasants into an academic discipline of scientists and (2) the importance of political arguments for this process of scientification. Most of the time Wieland's methods to present his thesis are exemplary: either as biographies or as breeding project histories. So he can write about a great diversity of aspects; but from his point of view – the discipline history as applied science – he cannot show the great importance of economic forces controlling plant breeding. This short article will not diminish the high value of Wieland's book. My aim is only to outline some desiderata for a history of plant breeding which is not yet written. 相似文献

For the past four years, the Fund for Peace has ranked the Central African Republic, Somalia and South Sudan as the ‘most fragile states’ in the world, in its annual Fragile States Index (FSI). The three countries’ almost identical scores suggest comparability; however, critics raise concerns about the FSI's data aggregation methods, and its conflation of causes and consequences. This article treads the uncharted path of unpacking the empirical realities that hide behind FSI indicators. Drawing on data collected during field research in the three states, the authors investigate three security indicators (security apparatus, factionalized elites, and external intervention) and propose an alternative, qualitative appreciation. Each country's fragility is based on how security forces, elites and interventions evolved over time and installed themselves differently in each region of the country. The qualitative assessment presented here shows that not every indicator matters in all cases at all times or throughout the country. Most crucially, the authors unveil enormous differences between and within the FSI's three ‘most fragile states’. Such variations call for better‐adapted and more flexible intervention strategies, and for quantitative comparisons to be qualitatively grounded. 相似文献
