Modern cities in the open European space-economy are powerhouses of creative ideas, smart technologies, sustainable developments and socio-economic wealth. They play a pivotal role in the future of an urbanized Europe, but they are also confronted with grand challenges, notably far-reaching demographic transformations, environmental decay and climatological change, unequal social participation and ever-rising mobility trends. The challenges for urban environments may be turned into new opportunities, in particular, in such domains as advanced infrastructure and logistic systems, environmental and climate-neutral facilities, creative and knowledge-intensive strategies for socio-economic prosperity and well-being. Cities—and in particular metropolitan areas—may thus act as spearheads of sustainable economic growth for European countries. These observations call for appropriate long-range policy strategies for metropolitan areas—and networks of cities—in the highly diversified European space-economy. Such policy actions would need to be supported by solid, multidisciplinary and evidence-based research on the challenges and opportunities of urban environments in Europe. The main contribution of this paper lies in the systematic strategic approach to transform urban megatrends and challenges into research and policy concerns for Europe. The analytical framework employed to highlight and better understand such research and policy response in Europe from a typological perspective is built around four interconnected pillars (cornerstones) that form the focal points for identifying strategic future images that may be instrumental in mapping out the research and policy challenges for the “New Urban Europe”.  相似文献

In 1934, the Norwegian biochemist and physician Asbj?rn F?lling described an inherited metabolic disorder characterized by severe intellectual impairment, motor problems, and skin abnormalities. He found that affected individuals could be identified by the abnormal excretion of phenylpyruvic acid in their urine. The disorder, which F?lling initially termed imbecillitas phenylpyrouvica, would later come to be known as phenylketonuria or PKU. The present paper focuses on the story of F?lling's discovery and his subsequent contributions to the area of study. In the years that have followed, research on PKU has continued to play a major role in the neurosciences, shaping our understanding of genetic disorders, human metabolism, and brain development.  相似文献

Academic discourse about America's influence on Europe constitutes an important contribution to the understanding of intercultural transfer-processes. In this context particularly the twentieth century has to be considered, because it was during this period when the decline of more than 400 years of the Europeanisation of the world ran parallel to the beginning of its Americanisation. The thesis presented here pursues an aspect of Amercanisation which has hardly been analysed: namely, the direct and indirect American influences on the German universities and academic system after the Second World War. In this case, the term Americanisation does not mean a one-sided transfer of the American higher education system, but rather a gradual merging of American influences with the German university tradition.  相似文献

Recent research on American government and public life in the late 19th century suggests that the extensive growth of the American state during this time did not necessarily involve a corresponding expansion of national authority or effective executive bureaucratic administration. Rather, the American polity was characterized by what Wallace Farnham termed the “weakened spring of government,rdquo; a government that “failed to use the powers it had.” This study examines how the late 19th century Department of Justice exemplified this problem. Despite increased personnel, resources, and responsibilities, effective law enforcement by the department was often frustrated by corruption, partisan political activity by department personnel, and by traditional reliance on local, decentralized responsibility for law enforcement. Examples of this were the attempts by the Justice Department to protect federal timber lands and enforce the federal election statutes in the south. Moreover reforms within the department were little more than “patchwork” efforts to achieve effective enforcement capacities.  相似文献

This paper examines the relationship between the newly formed kingdom of Portugal and the papacy in the second half of the twelfth century. The kings of Portugal sought a close alliance with the papacy and their relationship has been seen as that of ‘vassal’ and overlord. However, it seems likely that this alliance owed more to the tradition of monastic protection grants. The act of homage performed to the papal legate by King Afonso I is an example of a wider use of the homage ceremony. Homage was not only used to cement ‘feudal’ bonds, but also to make peace or to confirm pacts and agreements. The annual census paid by the kingdom to Rome was part of the same grant of protectio. The papal–Portuguese letters used the same language and terminology as ecclesiastical protectio, which was awarded by the papacy to monasteries, churches and eventually kingdoms and kings.  相似文献

The heart‐shaped, or cordiform, maps of the sixteenth century, including those by Oronce Fine, Peter Apian and Gerard Mercator, have long intrigued historians. Most writers have considered the heart shape a product only of mathematics, but some have recently offered other interpretations for the use of the heart. A classificatory system devised by d'Avezac in 1863, however, has impeded our understanding of the cordiform map, particularly in the matter of what is considered to be such a map. The nature of his classification and its reception by other writers since the late nineteenth century are examined in order to elucidate new directions for the study of the use of the heart shape in sixteenth‐century cartography.  相似文献

The present article focuses on the epistemology of one of the leading lappologists of this country, the late J. Qvigstad (1853–1957). It is not surprising to find a preoccupation with the presence or absence of ?cultural traits? in his studies of the Sami of his time. A closer look at the micro demography of his informants does however suggest a misinterpretation on the part of Qvigstad, of the situation of the Sami and their local communities.  相似文献
