Even though the European Union's merger regime has been warmly received, three distinct critiques of European policy in this field are identified. In acknowledging these critiques, this article reviews EU merger policy and suggests ways in which it might be reformed in the future. However, in order to understand the particular form that the policy now takes, emphasis must be placed on the context within which the European model of merger control has evolved. Three factors are considered: the rationale underpinning the policy; the origins of the policy as a hard-fought compromise among the (then) 12 members of the Union; and the role played by supranational actors in the implementation and enforcement of the policy. These three European characteristics of the policy help to explain the distinctiveness of the EU model.  相似文献

The fastest retail-system transformation in history has beensweeping across the emerging markets of East Asia, Central andEastern Europe, and Latin America over the past decade withprofound impacts on economies and societies in those regions.Conceptualized by researchers in development studies and agriculturaleconomics as the ‘supermarket revolution in developingcountries’ (see, for example, Reardon et al., 2003; Reardon,2005; Reardon and Hopkins, 2006; Humphrey, 2007; Reardon etal., 2007), that transformation has been driven not only bydemand-side forces such as urbanization and income growth inthe emerging markets, but also by supply-side forces such  相似文献

We discuss a simple methodology to enable a statistical comparison of human population with the vegetation of North America over the past 13,000 years. Nonparametric kernel methods are applied for temporal and spatial smoothing of point data obtained from the Neotoma Paleoecology Database and the Canadian Archaeological Radiocarbon Database, which results in sequences of maps showing the development of population and different plant taxa during the Holocene. The estimation of smooth spatial and spatio-temporal cross-correlation functions is proposed in order to detect relationships between population and vegetation in fixed time intervals. Furthermore, the effects of varying environment on demographic changes as well as potential impacts of populations on plant taxa over time are analyzed. Pointwise confidence bands for cross-correlation functions are computed and a robustness analysis is performed to assess the significance of obtained results. Considering the example of oak, an interpretation of our results for eastern North America shows the value of this methodology.  相似文献

This paper reports on the results of archaeological field excavations at the site of Kara-tepe, in the semi-autonomous region of Karakalpakstan in northwestern Uzbekistan. Investigations at the site in 2008–2009 turned up an unusually rich assemblage of remains from a household context. Combined analysis of the household botanical and faunal remains has allowed us to reconstruct the agropastoral practices of local inhabitants in this oasis region during a critical period of social and environmental change in the Early Medieval transition (4th–5th centuries a.d.). The results of the study raise important new questions about agropastoralism in the oases of Central Eurasia, highlighting continuities of practice between oasis and steppe populations, and revealing dynamic changes in these systems over time.  相似文献

During the years 1610 and 1611, two Ursuline novices underwent an exorcism in southern France. In the spring of 1611, their confessor, Father Louis Gaufridy, was condemned of witchcraft and rape by Dominican inquisitors, and burned at the stake by state officials. The Dominican inquisitors found Father Gaufridy guilty of causing the Ursulines to be possessed by demons, and luring the young women to caves where they participated in illicit activities. Rather than accepting the role of victim, the Ursulines, working in collusion, accomplished the miraculous: public exoneration, and reintegration into their religious community accompanied not only by a reclaimed stature as women religious, but by an elevated stature. Through an intricate play of accusation and expiation, carefully worked through the demons that possessed them, the Ursuline novices reconstructed themselves as virtuous women religious.  相似文献
