The possibility of lead isotope fractionation in ancient lead production is examined. Kinetic theory relating to isotopic fractionation in non-equilibrium evaporation is considered and the feasibility of the alteration of lead isotope abundance ratios in ore roasting and smelting is assessed. Previous experimental work is shown to have been inconclusive and conclusions are drawn on the need for further research to quantify the possible extent of fractionation in practice.  相似文献

This paper demonstrates that the morphology of ordinary rural roads tells much about regional development. It uses southern Ontario as a case study, but the principles may be applied widely. It is a plea for recognition of a deep heritage in unspectacular things: ditches, fence-lines, culverts, jogs in the survey, and more. This paper also encourages local and regional planners to conserve signs of change in the roadscape and to celebrate them. Roadside evolution is worth publicizing, and unnecessary destruction of elements that enhance the story must be discouraged.
Cet essai démontre que la morphologie des routes rurales ordinaires en dit beaucoup au sujet du développement regional. On peut employer cet exemple de /'Ontario du sud mais les principes peuvent s'appliquer d'une manière plus large. Dans ce manuscrit on doit reconnaître /'heritage profond des elements communs: des caniveaux, des clotures, des aqueducs, des irrégularity de I'arpentage, etc. Cet essai encourage aussi les planificateurs i conserver ces signes du paysage routier et à les mettre en Évidence. On doit les faire connaître au public, et décourager leur déstruction.  相似文献

While the cancellation of a number of high‐profile loans because of corruption concerns has made headline news, the World Bank's principal approach to poorly governed countries is lending in order to support reforms. Although designed to be an apolitical technocratic development financier, increasingly the Bank has focused its attention and resources on promoting good governance in its borrowers. Bank lawyers and presidents have attempted to hive of apolitical aspects of governance by arguing a distinction between the rule of law and the political character of government, but this distinction is illusory. The Bank's inability to address the political embeddedness of poor governance in neo‐patrimonial governments skews risk assessments and impedes the formation of effective strategies. Reform of the charter would not eliminate the Bank's bureaucratic and political constraints.  相似文献

This essay analyzes the carved footprints in the Iron Age temple at ‘Ain Dara, Syria from a broadly comparative perspective. This methodology is necessitated by the fact that footprint iconography is very rare in ancient Near Eastern art. The diverse examples utilized in this paper to help explicate the footprints at ‘Ain Dara range from the Footprints of the Buddha (Buddhapadas) to the sullied feet of Jesus. Through analysis of footprint iconography in other religious contexts, I have drawn conclusions concerning the form and function of the temple footprints at ‘Ain Dara that have escaped other scholars of the ancient Near East.  相似文献
