ABSTRACT

The article analyzes the impact on statebuilding as an aspect of Ukraine’s integration with the EU. The Euromaidan had a profound, yet hardly recognized, effect on EU-Ukraine relations, particularly in terms of the EU’s subsequent support of domestic reforms in Ukraine. Following the Euromaidan, the EU supported Ukraine’s aspirations to enter “economic integration and political association” by concluding an Association Agreement – an agreement which exceeded the capacity of the Ukrainian state to implement it. To increase this capacity, the EU has supported reform of public administration and has provided far-reaching assistance on capacity building in the government. This article posits that since 2014 European integration has become tantamount with (re)building the state structures in Ukraine. Therefore, the significance of European integration for Ukraine goes beyond the implementation of the Association Agreement and extends to root-and-branch reform of Ukrainian state structures.  相似文献

Assurance , a British warship of 44 guns, was lost on the Needles of Wight, UK, in 1753. Pomone , a British 5th rate 38-gun frigate of the Leda class, followed in 1811. Designated a'protected wreck' in 1975 this multi-period site was investigated under a UK Government licence. Despite her total disintegration, Pomone left artefact scatters attesting to her size, character, resting position and evidence of her cabin plan. This archaeological evidence is compared with two surviving sister ships, and the presumption of incomprehensible 'scrambling' on Muckelroy Class 5 wreck sites is robustly challenged. The licencee reviews the organization and methodology of 25 years of licenced activity on this site and concludes that the UK policy of promoting invasive investigation of historic shipwrecks cannot be readily reconciled with the principles of sustainability which are now embodied in European Agenda 21.  相似文献

20世纪初,中国古物大量流散欧美,价格高、易携带的古玉尤为大宗。笔者于1979年-1980年曾旅行探访20余所博物馆,在各馆库房仔细研究玉器。到1990年代,再多次前往重要的馆藏从事专题研究。"良渚玉器上的刻画符号"就是当时我密切关注的专题之一。在本篇中,笔者除回顾百余年流散欧美的良渚古玉收藏及出版情况,介绍四件圆周有刻符的良渚玉璧外,也略论约16至20世纪仿赝良渚古玉的特征。  相似文献

The eagle owl (Bubo bubo) is the main leporid predator among nocturnal raptors. Although its role as an accumulator of leporid remains in archaeological sites has already been demonstrated, the taphonomic signature of this predator has not been properly characterised. Here we present the analysis of two samples of modern leporid remains recovered from eagle owls' nests with the aim of contributing new data to this subject. Results show that although variability occurs, the observed anatomical representation, breakage and digestion patterns allow us to distinguish this raptor from other rabbit predators. Finally, several characteristic features are noted to distinguish eagle owls as agents of leporid bone accumulations in the fossil record. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献
