This study builds an interactive, quantitative model to explain U.S. foreign aid allocations. We develop an explanation based on Kingdon's multiple streams model to argue that aid decisions are the result of trade ties, socialist orientation, human needs, and the political ideologies of the administration and the senate interacting with adjustments to baseline funding. We find that there are significant conditional relationships between economic and security-related assistance and our external and domestic variables with external variables generally being more important. The findings have implications for the study of public policy, the future of the foreign aid program, and theoretical attempts to develop more generalizable explanations of policy that encompass foreign and domestic issues. 相似文献

这篇寓言小说叙述了“我”的一次坐飞机旅行的不寻常的经历,以考古学家最常用的发掘工具-一把金色的手铲为线索,以文学性的语言刻画了上世纪80年代三个美国考古学家的生动形象。新生哲学家是一个理论家,自诩为“理论的创造者”,而将他人贬为“理论的消费者”。70年代为骄子以编辑他人的见解为生,擅长将他人的观点变成自己的观点。以上二位从不参加田野发掘,但是却位居要津,声名显赫。老前辈是个传统而又守旧的考古学家,常年奔波在野外考古工地,但由于跟不上形势的发展而被迫提前退了休。他们争论的话题包括:考古学理论、基建考古学、课题考古学、考古学家的道德等等。小说发表后,由于其语言生动风趣,切中了考古学界的种种弊端,立即在学术界引起了轰动,堪考古学史上的一篇旷世奇文。 相似文献

先秦时期.天灾和人为的灾荒给人民带来极大的困苦,先秦诸子为此提出以农为本的思想和储仓措施,探讨赈济策略,并提出诸多有效的措施。其中某些抗灾救荒的思想至今还有借鉴意义。 相似文献

微生物是影响古代壁画安全保存与展示的一个重要因素,其检测是壁画保护研究的重要环节。分子生物学技术通过直接分析微生物遗传物质确定种属,可以避免传统检测技术必需的微生物培养过程,不仅快速、全面,更重要的是能够确定主要致病菌。本研究用分子生物学技术检测中国北方两个5世纪壁画墓,确定导致壁画菌害的主要种群为假诺卡氏菌(Pseudonocardia sp.),为微生物病害治理和预防提供了基本依据。 相似文献

Guest editorial by Sophie Day 《Anthropology today》2009,25(3):1-3
The 1990s saw government initiatives restricting immigration in many countries, and a good deal of popular unease. Associated policies have targeted sex workers, as with the Policing and Crime Bill that is currently in its Third Reading in the House of Commons (UK). In the name of 'victims' of a trade organised by 'evil' traffickers, this Bill seeks further sanctions against all of those involved. This editorial asks whether initiatives during the current recession might not seem to succeed but for the wrong reasons. Immigrants are already leaving the UK in search of a living while local workers, who were promised safer working conditions in the wake of the murder of five women in Ipswich (2006), will be punished more and more. With its apparently humanitarian efforts to 'stop the traffic', the UK government will turn out to have replaced our 'slaves' from abroad with home-grown substitutes, and effectively solidified and further excluded an underclass. This situation suggests striking parallels with the panic over white slavery during the last comparable period of globalisation culminating in the First World War. 相似文献

The beginnings of extractive metallurgy in Eurasia are contentious. The first cast copper objects in this region emerge c. 7000 years ago, and their production has been tentatively linked to centres in the Near East. This assumption, however, is not substantiated by evidence for copper smelting in those centres. Here, we present results from recent excavations from Belovode, a Vin?a culture site in Eastern Serbia, which has provided the earliest direct evidence for copper smelting to date. The earliest copper smelting activities there took place c. 7000 years ago, contemporary with the emergence of the first cast copper objects. Through optical, chemical and provenance analyses of copper slag, minerals, ores and artefacts, we demonstrate the presence of an established metallurgical technology during this period, exploiting multiple sources for raw materials. These results extend the known record of copper smelting by more than half a millennium, with substantial implications. Extractive metallurgy occurs at a location far away from the Near East, challenging the traditional model of a single origin of metallurgy and reviving the possibility of multiple, independent inventions. 相似文献
