This article presents a preliminary attempt to characterise Upper Thai-Malay Peninsula prehistoric iron technologies based on assemblages from two recently excavated coastal sites: Khao Sam Kaeo and Phu Khao Thong. These are the earliest known sites involved in the early trans-Asian exchange that connected the eastern Indian Ocean to the South China Sea from the mid-first millennium bc. It is from this period that iron assemblages start appearing at both continental and insular Southeast Asian sites. Three models have been offered confronting an indigenous vs. Chinese or South Asian impetus for the introduction of iron metallurgy in Southeast Asia. These models are discussed in the light of the metallographic and compositional analyses of iron and slag assemblages from these two sites using optical microscopy, scanning electron microscopy with energy dispersive spectrometry, energy dispersive X-ray fluorescence and slag inclusion analysis techniques, together with other production materials from these and other contemporaneous Southeast Asian sites.  相似文献

Abstract: This article explores the ways that responsibility for social welfare and wellbeing is framed by service providers, activists and the state in two moments of welfare restructuring in the United States. Many service providers and activists rework notions of obligation and responsibility to challenge the state to meet its obligations to its citizens. They enact an oppositional politics of obligation and care that is rooted in normative values rooted in family and faith. The article concludes with a consideration of the potential for an oppositional politics of obligation.  相似文献

This article will examine requests for repatriation submitted by Nigerian subjects in the last decade of colonial rule in Nigeria. Requests for repatriation from this time provide insights into the motives, outcomes and impact of a growing trend among Nigerians to travel abroad for work, studies, pilgrimages and adventure. This mobility reflected both easier access to the means to travel and the empowerment of Nigerians to realise their economic, social and cultural aspirations beyond the borders of Nigeria. Once abroad, many became destitute and unable to pay for their return back home, and requests for their repatriation were then made to the colonial administration in Nigeria. A review of the files regarding the process of repatriation exposes divergent perceptions between colonisers and colonised of the rights and obligations structuring the colonial relationship. It will be seen that a very limited range of options was available to the British administration in Nigeria in dealing with those who defied, ignored or reinterpreted rules aimed at monitoring and regulating the identities and movement of Africans. Thus, the history of repatriations reveals both the impotence of the colonial regime in imposing limits on the mobility of its African subjects, and the various ways in which Africans imposed their own notions of flexibility and ambiguity in response to colonial policies.  相似文献

We compare the relative impacts of political and socioeconomic factors on state restrictiveness toward abortion during the pre-Roe, pre-Webster and post-Webster time frames. This analysis tests the value of cycle theory, where shifting epochs dominated by liberalism and conservatism enhance the role of political variables in shaping policy formation. It also tests the explanatory value of public opinion theory which holds that bimodal issues which cut across party lines accentuate the role of socioeconomic variables in shaping issue evolution. The results of this analysis lend support to cycle theory and public opinion theory, although public opinion theory receives stronger support. When socioeconomic independent variables are regressed against our dichotomous measures of state restrictiveness toward abortion, they explain more variance than political independent variables. Political variables were more important in the conservative era (1989) than in the liberal era (1972).  相似文献

In West Africa, containment practices have long been localized in their production, moulded by environmental forces, and scaled to the human body. In the twentieth century, fossil fuels have changed how people keep and carry things. But newer technologies have tended to alter, rather than eliminate, older forms of storage.  相似文献
