In this article, I discuss the role of the three Scandinavian central banks in the establishment of the Bank for International Settlements (BIS) in 1930, and in the international lender of last resort operation towards Austria in 1931. I argue that small central banks were reluctant supporters in the establishment of the BIS and free riders in the Austrian crisis, even though there were marked differences in their attitude to international cooperation. These results run counter to the views of those International Political Economy (IPE) theorists who argue that small states should be in favour of international cooperation. On the other hand, the evidence seems to confirm Kindleberger's hypothesis that small countries were free riding during the international financial crisis of 1931, and that therefore there is a need for some coordinating mechanism, or a hegemon, in such crises. 相似文献

The process of globalization is increasing competition between urban areas for the attraction of investment. Within this context the paper initially highlights the impact of global change on city economies linking this to international investment within the real estate market. Factors influencing diversification strategies and international investment activity within property markets in central Europe are considered relative to a range of performance criteria. Office markets in Prague, Budapest and Warsaw are forwarded as case study examples to assess the degree of maturity that is occurring in these former socialist cities based on the activity of investors and end‐users including the extent to which there are dual markets operating for local and international actors. 相似文献

Experimental Heating of Moravian Cherts and its Implication for Palaeolithic Chipped Stone Assemblages 下载免费PDF全文
The applicability of colour, magnetic susceptibility and remanent magnetization measurements for the identification of heated or accidentally burned Palaeolithic cherts from Moravia (Czech Republic) is tested in this study. We conclude that all these methods are usable. Colour changes are best detectable in materials heated at between 250–350°C, while magnetic susceptibility and remanent magnetization change at higher temperatures, closer to 600°C. This latter temperature, however, is usually destructive for cherts and is probably evidenced by accidentally burned artefacts. With the use of the three methods, we managed to identify three probably heated chert artefacts from two early Upper Palaeolithic assemblages from Moravia. 相似文献

Was He Murdered or Was He Not?—Part II: Multi‐Elemental Analyses of Hair and Bone Samples from Tycho Brahe and Histopathology of His Bones 下载免费PDF全文
J. Kučera K. L. Rasmussen J. Kameník M. Kubešová L. Skytte C. Povýšil V. Karpenko V. Havránek P. Velemínský N. Lynnerup J. Brůžek J. Smolík J. Vellev 《Archaeometry》2017,59(5):918-933
Hair and bone samples procured from the remains of Tycho Brahe were analysed by several analytical techniques. In segmented hair samples, concentrations of Fe, As, Ag and Au at the tips exceeded values for the contemporary population; however, they decreased towards the hair bulbs, similarly to Hg, indicating that recent exposure that was discontinued ~2 months prior to Brahe's death. Several other elements did not follow this pattern. Analyses of bones revealed signs of long‐term exposure to Au, while many other elements were within expected ranges. Histopathological examination of bone sections yielded no signs of severe bone metabolic disorders. 相似文献

Phenol Formaldehyde Revisited—Novolac Resins for the Treatment of Degraded Archaeological Wood 下载免费PDF全文
Archaeological wood is usually severely degraded. The Norwegian Viking Age Oseberg find exemplifies problems arising due to past conservation treatments and the need for new types of preservatives. Phenol formaldehyde (PF) has been investigated as a consolidant for alum‐treated wood. X‐ray tomography has revealed that it is possible to obtain a porous structure inside the wood, ensuring ethical acceptability by allowing re‐treatment. In order to understand the curing mechanics, the kinetics of the initial condensation reaction were elucidated at room temperature. It was found that a second‐order reaction using both phenol and formaldehyde concentrations is the most probable mechanism. 相似文献
