The accumulated published database of stable lead isotope analyses of ore and slag specimens taken from Anatolian mining sites that parallel the Black Sea coast has been augmented with 22 additional analyses of such specimens carried out at the National Institute of Standards and Technology. Multivariate statistical analysis has been used to divide this composite database into five separate ore source groups. Evidence that most of these ore sources were exploited for the production of metal artefacts during the Bronze Age and Phrygian Period has been obtained by statistically comparing to them the isotope ratios of 184 analysed artefacts from nine archaeological sites situated within a few hundred kilometres of these mining sites. Also, Appendix B contains 36 new isotope analyses of ore specimens from Central Taurus mining sites that are compatible with and augment the four Central Taurus Ore Source Groups defined in Yener et al. (1991). 相似文献

Aid agencies claim that their development expertise and advisory services are more important than their funds. Development research databases highlight broader problems in the knowledge management systems that have been established to record and distribute that expertise. In practice, distilled digested mini‐facts disseminated electronically risk perpetuating rather than reducing dependence. A banking model of knowledge and knowledge sharing stymies learning because it undermines and devalues learners’ initiative and responsibility. More consequential than detached bits of information is learning, largely initiated, maintained, and managed by those seeking to change their situation. Problem‐solvers must be directly involved in generating the knowledge they require. Achieving information affluence in poor countries cannot rest on transfer and absorption but rather requires a generative process with strong local roots. 相似文献

Prior literature suggests that presidents use signing statements to unilaterally move policy closer to their own ideal point after Congress has already voted on and passed a particular bill. Congress, however, retains the ability to revisit and amend the law by passing another bill. A presidential signing statement may thus make a law less durable and more likely to be amended in the future. To investigate this relationship, we examine all laws passed from the 95th through the 108th Congresses in order to demonstrate the specific influence of presidential signing statements on future congressional amendment activity. The results of our analysis lend support to the theory that laws receiving presidential signing statements are in fact more likely to be revisited and revised by Congress. These findings add to the literature both on presidential signing statements as well as the evolution of laws. 相似文献

Foundation myths by definition are politically focused tales, describing the origin of nations, states, ruling dynasties, clans, and other consanguineal groups. The myths of Tan’gun and Chumong are the oldest extant foundation myths of Korea, but only the Myth of Tan’gun has had a continuous influence on the affirmation of Korean polities and nationalism for over a thousand years. This article explores why that has been the case. 相似文献

THE RELEVANCE of ‘closure theory’ to archaeology is discussed, and it is argued that the role of material culture in shaping medieval group identities was enhanced by taxation on movable property during the 13th century. Emphasis on monetary value led to concepts of ranking expressed in sumptuary laws and the use of symbols in late medieval contractual society. 相似文献
