This paper reports on the methodology and an application of a dialectical approach to research and development, planning. The methodology features a structured debate followed by argumentation analysis. The argumentation analysis in turn is followed by an assessment of the plausibility of the arguments. The application involved using the methodology to assess the level of funding for research and development for a transportation system that would employ advanced technology. The Dialectic Inquiry process, and specifically, the plausibility rating activity, were seen as valuable aids for policy analysis. 相似文献

Cobalt-blue colorant was first used in the 18th Dynasty in the New Kingdom of Egypt. The source of this cobalt was cobaltiferous alum from the Western Oases of Egypt. The use of this alum, especially in glass, was suddenly limited at the end of the 18th Dynasty. There is little evidence of the production of cobalt-blue glass in the Ramesside Period (the 19th–20th Dynasties) in the New Kingdom of Egypt. In this study, we brought a portable X-ray fluorescence spectrometer to two archaeological sites located in the Memphite region and used it for onsite analyses of Ramesside cobalt blue-colored glasses and faiences. This method revealed that the compositional characteristics of the cobalt-blue colorant in these Ramesside glasses and faiences is different from the colorant derived from cobaltiferous alum used in the 18th Dynasty, based on the comparison of transition metal composition and alumina content with those of the cobalt blue-colored artifacts from the 18th Dynasty. This result suggests that a new cobalt source other than cobaltiferous alum from the Western Oases was utilized in Egypt during the Ramesside Period. 相似文献

This article examines the potential future of the U.S. environmental justice movement in a time of economic uncertainty, increasing inequality, and an ascendant white right. It traces the origins of “whiteness” as a historically contingent concept within American history and its relationship to current politics in general and the politics of the environment in particular. It reviews the emergence of research, public concern, and action over the linkage between environmental pollution, race, and class. After offering a critique of the contrary empirical findings of academic researchers, the article identifies two roads for future work in the field, and their potential pitfalls. 相似文献
