Change within the academic discipline of geography comes about as a result of internal struggles for disciplinary hegemony, for its ‘heart and soul’ and for resources. One approach to the study of these struggles is through examination of textbooks, authoritative statements of the discipline's contemporary condition. Analysis of a small number of recent texts shows that they reflect a current contest within human geography between two groups, stereotyped as ‘spatial analysts’ and ‘social theorists’. The former are being ‘written out’ of disciplinary history, despite their continued vitality. Reasons for the continued presence of, and investment in, spatial analysis within human geography are rehearsed. 相似文献

Summary. A number of settlements and other traces of occupation have been identified in the mountainous areas near to tin and copper deposits in the Erzgebirge, and some of them excavated. The newly collected evidence seems to suggest that many small sources of metals, both tin and copper, were exploited, the former metal by washing from the river and creek beds. Though these sources were more modest than the British and Spanish tin supply, they seem to have served the Bohemian and Saxon Bronze Age cultures well. 相似文献

American constitutional history in the early national period seems at times to be a conversation—or an argument—among Virginians. There's James Madison, George Washington, George Mason, John Taylor of Caroline County, Judge Spencer Roane, John Randolph of Roanoke, to mention only some. At the center of this constellation were John Marshall and Thomas Jefferson. 相似文献

Summary. Epigraphic and isotopic analysis of the lead ingots recovered from a shipwreck off Capo Passero (in Sicily) in mid-2006 suggests that the ingots were produced in Spain, in the Cartagena region. The shipwreck is estimated to have occurred around 38 BC, at the beginning of the Hispanic era. This provides further evidence that the Romans were trading lead throughout the Mediterranean Sea. 相似文献

Abstract: This article builds upon the literature on neoliberalism and environment as well as studies on community forestry by examining the creative accommodations that rural producers have made in navigating Mexico's neoliberal turn. In contrast to previous work that emphasizes macro‐level processes (eg privatization of public natural resources) and local resistance, I employ Bourdieu's theory of practice to examine the symbolic and material dimensions of local responses to neoliberal policy reform. Drawing on research from nine communities in the state of Quintana Roo, I argue that local producers have accommodated neoliberal policies and programs by adopting hybrid logics, property regimes, forms of organization, and modes of exchange. Moreover, I contend that these creative responses constitute elements of a longstanding “culture of accommodation” to institutional change that predates Mexico's neoliberal reforms. 相似文献
