In the 1950s, a small group of political, scientific and business leaders in West Germany were determined to build a center for nuclear reactor research and development. They characterized the venture as a three-way partnership, intending to set an example for a scientific-technical age. The project was eventually carried out, but not without much conflict. The attempts at cooperation show parties with divergent sets of criteria that they only inadequately reconciled, and the struggles display their conflicted understandings of both the public-private boundary and the scientific role. New archival material lets us inspect more accurately the workings of the proposed collaboration. It shows how the conflicts developed in practice, despite all parties' expressions of commitment to cooperation.  相似文献

Changes in resource use over time can provide insight into technological choice and the extent of long-term stability in cultural practices. In this paper we re-evaluate the evidence for a marked demographic shift at the inception of the Early Iron Age at Troy by applying a robust macroscale analysis of changing ceramic resource use over the Late Bronze and Iron Age. We use a combination of new and legacy analytical datasets (NAA and XRF), from excavated ceramics, to evaluate the potential compositional range of local resources (based on comparisons with sediments from within a 10 km site radius). Results show a clear distinction between sediment-defined local and non-local ceramic compositional groups. Two discrete local ceramic resources have been previously identified and we confirm a third local resource for a major class of EIA handmade wares and cooking pots. This third source appears to derive from a residual resource on the Troy peninsula (rather than adjacent alluvial valleys). The presence of a group of large and heavy pithoi among the non-local groups raises questions about their regional or maritime origin.  相似文献
