Transport corridors are viewed as a promising way forward in European Union (EU) transport policy, assumed to contribute positively to regional economic development. However, the validity of this assumption is not evident. The aim of this paper is to empirically test whether agglomeration economies in European transport corridor regions are positively related to indicators of regional economic development compared to regions outside the scope of corridors. The results build on the notion that the type of agglomeration economy in combination with the structure of the economy matters for prospects of structural economic growth in different regions. In this way, the analysis not only contributes to enhancing the empirical scrutiny of the corridor concept in EU transport policy, but also provides new insights into how corridors contribute to regional economic growth. We find only limited evidence for a corridor effect across European regions on productivity and employment growth externalities. Instead, we find a large degree of spatial heterogeneity interacting with corridors—a heterogeneity that has been little recognized in EU policies. We suggest that recent attention to place-based development strategies may accord well with the kinds of agglomeration effects related to corridor development observed in this study. 相似文献

Optically stimulated luminescence dating of young fluvial deposits of the Middle Elbe River Flood Plains using different age models 总被引:1,自引:0,他引:1

In the last few decades optically stimulated luminescence (OSL) dating has become an important tool in geochronological studies. The great advantage of the method, i.e. dating the depositional age of sediments directly, can be impaired by incomplete bleaching of grains. This can result in a scattered distribution of equivalent doses (DE), leading to incorrect estimation of the depositional age. Thoroughly tested protocols as well as good data analysis with adequate statistical methods are important to overcome this problem. In this study, samples from young fluvial sand and flood plain deposits from the Elbe River in northern Germany were investigated to compare its depositional ages from different age models with well-known historical dates. Coarse grain quartz (100–200 μm and 150–250 μm) and polymineral fine grains (4–11 μm) were dated using the single aliquot regenerative (SAR) dose protocol. The paleodose (DP) was calculated from the DE data set using different approaches. Results were compared with the development of the Elbe River, which is well-documented by historical records and maps covering the last 1,000 years. Depending on the statistical approach it can be demonstrated that depositional ages significantly differ from the most likely depositional age. For the investigated coarse grain quartz samples all ages calculated from the MAM-3UL, including their uncertainties, are within the historical documented age. Results of the polymineral fine grain samples are overestimating the historically documented depositional age, indicating undetectable incomplete bleaching. This study shows the importance of using an adequate statistical approach to calculate reliable OSL ages from fluvial sediments. 相似文献

The guest coeditors of this issue set a context in which to view a previously unpublished article of Frank Harary. The Harary article is followed here by contemporary material of Joseph Kerski that addresses similar real‐world issues. The two together, along with the context, serve as a springboard to launch the reader into the rest of the materials in this special issue devoted to graph theory and network science. Los coeditores invitados de esta edición establecen marco contextual para una lectura de un manuscrito inédito de Frank Harary. El artículo de Harary es presentado y complementado con material contemporáneo de Joseph Kerski que aborda problemas similares del mundo real. Los dos juntos y el marco conceptual sirven de base al lector para el resto de los materiales en este número especial, dedicado a la teoría de grafos y la ciencia de la redes. 本专辑的客座合作主编发表了一个评论,回顾Frank Harray先前未发表的论文。Harary的论文和当代Joseph Kerski的论文均关注相似的现实世界问题。将两者内容进行对比,结合原文,可以使读者更深入地了解本专辑中有关图论和网络科学之外的其他内容。 相似文献

The Internet is an interconnected network and cyber security requires collective action. How that action is organised has important implications for national security, including the defence against cyber attacks and malicious activities. This article explains the origins and institutionalisation of cyber security in Australia—particularly ‘civilian cyber security’. The authors trace the origin of Australia’s first computer emergency response team and explain how this organisational form spread from the USA. Through it, Australia helped enable international cooperation. Domestically, however, the authors argue that the Australian government has struggled with the delegation, orchestration and abdication of responsibility for civilian cyber security, underinvesting in civilian organisations while overrelying on military and intelligence agencies. The history of this organisational field provides valuable insight into how to improve national policy and operations for cyber security. 相似文献

AbstractThe history of both the Red Cross and the Japanese Red Cross is based on a teleological and eurocentric narrative which is strongly shaped by national histories and focused on persons. To assume 1863 as the founding date of the Red Cross is highly debatable, considering that most national relief organisations were renamed ‘Red Cross Societies’ only in the 1880s. In this Japan is no exception, since first a Haku-Ai-Sha (Philanthropic Society) was founded in 1877 and then turned into the Japanese Red Cross Society in 1887. Japanese actors must be regarded as intrinsically motivated and active participants in the Red Cross movement who saw an ideal and a model in the Euro-American ‘way of civilisation’ and humanity. It has taken about 30 years to turn the Haku-Ai-Sha in Japan into a humanitarian society which is accepted both at home and abroad and, with its 728,507 members in 1900, which constituted the largest Red Cross Society in the world. 相似文献

ABSTRACTThis article is a historiographical exploration of the special forms of knowledge generation and knowledge transmission that occur along local cultural boundaries in the modern neurosciences. Following the inauguration of the so-called “Law on the Re-Establishment of a Professional Civil Service” in Nazi Germany on April 7, 1933, hundreds of Jewish and oppositional neurologists, neuropathologists, and psychiatrists were forced out of their academic positions, having to leave their home countries and local knowledge economies and traditions for Canada and the United States. A closer analysis of their living and working conditions will create an understanding of some of the elements and factors that determined the international forced migration waves of physicians and clinical neuroscientists in the twentieth century from a historiographical perspective. While I am particularly looking here at new case examples regarding the forced migration during the National Socialist period in Germany, the analysis follows German-speaking émigré neurologists and psychiatrists who found refuge and settled in Canada. These individuals form an understudied group of refugee medical professionals, despite the fact that the subsegments of refugee neurologists and clinical psychoanalysts in the United States, for example, have been a fairly well-investigated population, as the works of Grob (1983), Lunbeck (1995), or Ash and Soellner (1996) have shown. This article is primarily an exploration of the adjustment and acculturation processes of several highly versatile and well-rounded German-speaking physicians, who had received their prior education in neurology, psychiatry, and basic brain research. They were forced out of their academic home institutions and had to leave their clinical research fields as well as their disciplinary self-understanding behind on the other side of the Atlantic. 相似文献
