Summary. Recent archaeological work has thrown fresh light on the region of Moravia and SW Slovakia (ČSSR) at the time of the Roman Empire. It is now apparent that, as on other frontiers, Roman influence extended far beyond the Danubian Limes . This paper describes six sites with Roman-style masonry buildings; one of the sites, Mušov, has produced evidence of Roman military occupation and is associated with the Marcomannic Wars of Marcus Aurelius; the other five, however, are of civilian character with an interesting admixture of Roman and German structures and artefacts. These sites provide us with an insight into the relationship of the client kingdom of the Quadi with Rome.  相似文献

Abstract: The term “neoliberalism” has come to be used in a wide variety of partly overlapping and partly contradictory ways. This essay seeks to clarify some of the analytical and political work that the term does in its different usages. It then goes on to suggest that making an analytical distinction between neoliberal “arts of government” and the class‐based ideological “project” of neoliberalism can allow us to identify some surprising (and perhaps hopeful) new forms of politics that illustrate how fundamentally polyvalent neoliberal mechanisms of government can be. A range of empirical examples are discussed, mostly coming from my recent work on social policy and anti‐poverty politics in southern Africa.  相似文献

A problem which has arisen in discussions of an elm-disease explanation for the Neolithic elm decline has been the lack of fossil records of Scolytus scolytus (F.) (elm bark beetle), which is the main carrier of the fungus which causes the present epidemic of Dutch Elm Disease. Now, the discovery of wing cases of two individuals from elm decline deposits at Hampstead Heath, London, proves that the beetle was present in Britain during this episode. The deposits in which it occurs are described, and the various implications for elm disease causing, aiding or at least occurring during this stage of the early Neolithic are discussed.  相似文献

An investigation of three Andean towns in their regional setting forms the basis for an assessment of urban-rural demographic differences. The towns are found to have been ethnically distinct, with a larger proportion of whites than the mainly Indian rural areas. The urban populations also had a larger surplus of women, lower average marriage ages for women but lower proportions married, a higher illegitimacy rate and a slightly older age structure. Trends in urban districts differed from those in rural areas. The towns suffered major population losses, and their share of the regional population fell from nearly 10% in 1778 to around 5% in 1841. The factors affecting population trends are examined in order to identify those which had a differential urban-rural impact. Earthquake and warfare were of key significance. In a regional context of economic depression and population stagnation, these two catastrophes instigated a major urban recession. The three towns shared in the urban decline experienced in many parts of Latin America, but their recession was particularly pronounced owing to the impact of catastrophes.  相似文献
