ABSTRACT

We integrate functional weed ecology with crop stable carbon and nitrogen isotope analysis to assess their combined potential for inferring arable land management practices in (semi-)arid regions from archaeobotanical assemblages. Weed and GIS survey of 60 cereal and pulse fields in Morocco are combined with crop sampling for stable isotope analysis to frame assessment of agricultural labour intensity in terms of manuring, irrigation, tillage and hand-weeding. Under low management intensity weed variation primarily reflects geographical differences, whereas under high management intensity fields in disparate regions have similar weed flora. Manured and irrigated oasis barley fields are clearly discriminated from less intensively manured rain-fed barley terraces in southern Morocco; when fields in northern and southern Morocco are considered together, climatic differences are superimposed on the agronomic intensity gradient. Barley δ13C and δ15N values clearly distinguish among the Moroccan regimes. An integrated approach combines crop isotope values with weed ecological discrimination of low- and high-intensity regimes across multiple studies (in southern Morocco and southern Europe). Analysis of archaeobotanical samples from EBA Tell Brak, Syria suggests that this early city was sustained through extensive (low-intensity, large-scale) cereal farming.  相似文献

Studies of transnational families tend to filter understandings of mobility and stasis through a bi-national framework that juxtaposes the movement of migrants across international borders with the immobility of in-place kin within equally static national spaces. This article examines the concept-metaphors of mobility and stasis through the eyes of later-life (over 50 year-old) Western migrants living in Penang, Malaysia and Bali, Indonesia. By treating “in-place” kin as mobile subjects I examine the extent to which the movement of individuals and families within and across a range of national borders affects the lives, concerns and movements of these older, Western migrants and retirees in Southeast Asia. By examining the concept-metaphors from the perspective of these migrants I illustrate the extent to which such people both succumb to yet exceed scholarly imaginings of im/mobility and juxtapositions between mobile selves and immobile others. Migrant thinking about these concept-metaphors, I suggest, complicates an ongoing tendency within the field of transnational family studies to view mobility and stasis as categorical opposites and offers fresh insights into the role and relevance of these concept-metaphors in the lives of Western migrants in Southeast Asia and their transnational relations with teenage and adult children, ageing parents and grandchildren.  相似文献

The Civil War and Reconstruction and the South's postbellum industrialization produced economic dislocation on a tremendous scale. One product of that economic upheaval was an increasing problem of infanticides and infant abandonments. This case study of Richmond, Virginia, examines patterns of abandonment and neonaticide as documented in records of the city almshouse and the city coroner. It demonstrates that race shaped the options available to women with problem pregnancies in that African American women had access to fewer social welfare unstitutions such as maternity homes. As a result, unmarried black women kept their out-of-wedlock babies more often than did whites, but they also committed infanticide at higher rates than did whites. Moreover, racial trends in infanticides and infant abandonment suggest that Ricomond's white working class experienced economic advancements at the turn of the twentieth century, while the city's black working class continued to live in depression-like conditions throughout the period.  相似文献
