The article discusses different conceptions of space and place in refugee studies, especially contributions from anthropology and geography. A main distinction is drawn between two understandings of space and place; an essentialist conception, stating a natural relationship between people and places and an alternative conception attempting to de-naturalize the relationship between people and places. The consequences of applying different conceptions of space and place for the development of refugee policies and representations of refugees and displaced persons are addressed. For many displaced persons, displacement is experienced as being physically present at one place, but at the same time having a feeling of belonging somewhere else. It is argued that though attempts to de-naturalize the relationship between people and places have been important for how the refugee experience is conceptualized, there has been too much focus on imagination accompanied by a neglect of the local perspective of migrants and displaced people. In the local perspective of forced migration, the present lives of displaced people are emphasized. Especially the attitudes from the host communities, the policy environment that displaced people are part of, and their livelihood opportunities are the focus of regard. 'Territoriality' and 'reterritorialization' of the relationship between people and places are discussed as tools to analyse the local perspective of forced migration in general and the strategies of internally displaced persons and their hosts in Sri Lanka in particular.  相似文献

The general premise for successful archaeological in situ preservation in wetlands is that raising the water table will ‘seal the grave’ by preventing oxygen from reaching the deposit. The present review reveals that this may not be the entire picture, as a change in habitat may introduce new plant species that can damage site stratigraphy and artefacts. However, reviews on the types and degree of damage caused by vegetation to archaeological remains preserved in situ in wetlands have hitherto only been sporadically treated in the literature. Thus, this paper provides an overview of the adverse effects that various plants species have on the preservation status of wetland archaeology.Disturbance, due to growth of roots and rhizomes of the surrounding soil is denoted contextual disturbance, whereas deterioration of archaeological remains per se acts by several root-related factors that may be spatially and temporally concomitant. In waterlogged anoxic environments, deterioration is mainly related to (i) preferential growth of roots/rhizomes due to nutrient uptake and lesser soil resistance, (ii) root etching due to organic acid exudates, (iii) microbial growth due to root release of oxygen and labile organic compounds, and/or (iv) precipitation of hydroxides due to root release of oxygen. For example, roots of some wetland plants, such as marsh horsetail (Equisetum palustre), have been documented to penetrate archaeological artefacts down to c. 2 m in waterlogged anoxic soils. Here, we demonstrate that cultural heritage site management may unintentionally introduce deep-rooted or exudate aggressive plants by invoking change in hydrological conditions. Moreover, the implementation of biomass energy utilization and agricultural root depth optimization on a worldwide basis stresses the need for more research within root and rhizome impact on archaeological remains in wetlands. In conclusion, the worst-case scenario may be in situ deterioration instead of preservation, and one essential threat to archaeological wetland sites is the impact of wetland vegetation.  相似文献

Today, exactly 500 years after the discovery of America, there is still a lot of controversy about the history of syphilis in Europe, especially about the Columbian and pre-Columbian hypotheses. This paper presents evidence for the presence of venereal treponematosis in the late Antiquity in France. The case that we examined comes from the necropolis of Costebelle (3rd-5th centuries AD; Hyères, Var, France). Grave no. 1 contained the well-preserved skeleton of a relatively old woman with the skeletal remains of an approximately 7-month-old fetus in her pelvic cavity. The osseous lesions of the fetal remains can be described in four groups: periosteal appositions on the skull vault (frontal and parietal); signs of periostitis on the long bones (bilateral cortical irregularities, predominantly on the left side, which affect first of all tibiae, femora, fibulae, radii and humeri, particularly in the metaphyseal region); some infraperiosteal detachment reminiscent of an infraperiosteal haematoma surrounding the distal extremity of the left forearm and the left hand; and finally, the irregular lesions of the humeral distal and proximal tibial metaphyses reminded us radiologically of Wimberger's signs. The most probable diagnosis of all the lesions mentioned above is that of a precocious congenital syphilis. This case consists of an argument against the epidemiological theories about the migration of Treponema pallidum from the New World back to the Old World starting at the end of the 15th century.  相似文献

This article focuses on how northern non-governmental organizations (NGOs) and their partners, community-based organizations (CBOs), are ‘working’ gender after a crisis. It explores the relationship between one NGO aiming to mainstream gender and a women's CBO in a village in southern Sri Lanka after the 2004 tsunami. The gender policies of the NGO and how the CBO has co-opted these policies are analysed in terms of discourse, interdependence, power and performance. Structural and individual challenges for working gender in post-crisis situations are analyzed and the constraints for making deep reaching changes that can alter gender relations are identified. Because of differences in the conceptualization and implementation of gender policies and practices, the CBO has manoeuvred to maintain its own interests, while the NGO has experienced disconnections in working gender between organizational levels and locations of implementation. In conclusion, it is argued that for changes to take place, knowledge production on gender needs to be locally situated and sensitive to the structural conditions and power relations with which organizations and communities engage.  相似文献
