Blood and protein residue identification in archaeological research has been a controversial subject for the last 20 years. This paper reports on the use of an improved protein radioimmunoassay (pRIA) technique in identifying protein residues. Results from the blind testing of the original and improved pRIA techniques in identifying bloodstains on experimental lithic artifacts are described and compared. We argue that the improved pRIA technique is highly sensitive and accurate for identifying protein residues to genus, and thus has excellent applications for archaeological research.  相似文献

Irish America today is at a stage of “late generation ethnicity,” designating an ethnic formation that reaches back many generations in the US and is not being significantly replenished from the country of origin. This is not necessarily a terminal state of ethnic affairs, but it is a transitional one, and the analytical challenge is to identify and understand the features and implications of “lateness,” what the sense of an ending means in the Irish American case. This essay will explore this question, drawing on field study among Irish communities in Chicago, and also consider some of the differences in worldview among Irish-Americans, particularly as these pertain to matters of immigration reform and undocumented Irish in the US.  相似文献

The declaration in 1932 of the United States to allow Philippine independence in March 1934 was an act that had a number of unintended consequences for the stability of the Far Eastern balance of power system. Given the state of tension existing in the international system between the major actors in the region: Japan, China, the Soviet Union, Great Britain and the United States, any movement in the existing boundaries of the international spheres of influence between them could generate a significant destabilizing reaction. The American proposal to allow Philippine independence was such an act. If America surrendered its position and interests in the Philippines, who would replace it? What would happen if it was not replaced? Was it realistic, given the nature of the international competition for resources and strategic position, all linked to the creation and use of maritime power, that the Philippines could exist ‘on its own..’. This essay will analyse how the United States and Great Britain dealt with this instability, as well as how those interactions allowed a closer and more harmonious Anglo-American informal strategic relationship to be developed. That relationship would thereafter evolve into a collaborative alliance aimed at deterring further Japanese expansion.  相似文献
