During the archaeobotanical investigation of Scythian–Sarmatian period (Early Iron Age), pits with crop processing waste, discovered in the floodplain of Donets River, eastern Ukraine, and charred remains of cereal grains, dominated by broomcorn millet, were recorded. The grains from the pits were radiocarbon dated to the fifth to first century BC. Those pits are distant from any known contemporaneous settlement. The apparent disconnection of these pits from any local settlement suggests that (1) millet was brought from other locations by mobile groups, or (2) millet was cultivated locally by populations whose settlements have left no discernible archaeological trace. The analysis of molecular biomarkers preserved in palaeosols that are stratigraphically connected to the pits revealed high levels of miliacin, a molecule that can be preserved in ancient soils and sediments, and that is consistent with broomcorn millet (Panicum miliaceum). High levels in miliacin in soils stratigraphically connected to the pits are interpreted as the result of a large biomass of P. miliaceum produced at time of soil formation. Our biogeochemical results applied to a palaeosol thus attest to the in situ cultivation of crops dominated by the broomcorn millet during the early Iron Age in the floodplain of Donets River. Biochemical examination of soils and palaeosols can thus provide useful information on past dynamics of land-use by ancient population, especially when settlements or macrobotanical remains are absent.  相似文献

The prose fiction that remembers the trials of starvation and eviction of the Great Famine (1845–50) often juxtaposes representations of blasted, infertile land with images of a green, idyllic Erin. Through a discussion of Mary Anne Sadlier's Bessy Conway (1861), Elizabeth Hely Walshe's Golden Hills: A Tale of the Irish Famine (1865) and John McElgun's Annie Reilly (1873), this article reveals that immigrant writers of the Famine generation often negotiate depictions of Famine-stricken wasteland with evocations of a pastoral homeland. In the case of the two Catholic novels, Bessy Conway and Annie Reilly, the pastoral becomes a point of ethnic identification through which the immigrants can recollect and reconstruct a sense of Irishness in exile. By contrast, Golden Hills, which focuses on the Anglo-Irish ascendancy, does not lament the mass exodus of afflicted Irish: the novel rather envisions emigration as a way to regenerate Ireland as locus amoenus.  相似文献

This article, which forms the introduction to a collection of studies, focuses on processes of state construction and deconstruction in contemporary Africa. Its objective is to better understand how local, national and transnational actors forge and remake the state through processes of negotiation, contestation and bricolage. Following a critique of the predominant state failure literature and its normative and analytical shortcomings, the authors identify four key arguments of the scholarly literature on the state in Africa, which concern the historicity of the state in Africa, the embeddedness of bureaucratic organizations in society, the symbolic and material dimensions of statehood and the importance of legitimacy. A heuristic framework entitled ‘negotiating statehood’ is proposed, referring to the dynamic and partly undetermined processes of state formation and failure by a multitude of social actors who compete over the institutionalization of power relations. The article then operationalizes this framework in three sections that partly conceptualize, partly illustrate who negotiates statehood in contemporary Africa (actors, resources and repertoires); where these negotiation processes occur (negotiation arenas and tables); and what these processes are all about (objects of negotiation). Empirical examples drawn from a variety of political contexts across the African continent illustrate these propositions.  相似文献
