This article examines how a regional NGO and a local‐issue GRO in Puerto Rico have approached health and environmental concerns over water pollution from pharmaceutical production, and the consequences this has had for corporate–community–government relations. Through the analysis of historical material, public meetings and interviews, the processes through which micropolitical patterns have developed, and through which residents least conciliatory towards the drug companies are silenced, are discussed. The article questions whether persistent conflict between the corporate–government alliance and grassroots environmentalists is attributable to a ‘gap in understanding’ and suggests that the relationship is better understood through the complementary theories of ‘coercive harmony’ and ‘deep capture’. In conclusion it points out that researchers should be wary of assisting or supporting negotiations, and rather should focus on critically examining the dynamics of ‘stakeholder dialogue’ as a negotiation between relative equals.  相似文献

We have explored laser depth profiling to obtain data sets for U-series as well as Sr analyses. Laser probing with an 81 μm spot size allows for the exploration of low uranium domains of up to 400 μm below the outer surface in tooth enamel. These low U domains will contain Sr isotope compositions of the individual, that are least affected by diagenetic Sr overprints. The small holes drilled for U surveying are not visible to the naked eye. Using larger spot sizes of around 233 μm, laser drilling can be used to obtain reliable U-series isotope data to a depth of approximately 1000 μm in enamel and around 1300 μm in bone. Furthermore, meaningful 87Sr/86Sr isotope data can also be obtained with this spot size. Using our sampling strategy, the overall damage to a human tooth is minute, as demonstrated on a Neanderthal tooth from Moula-Guercy. We expect that laser ablation depth profiling will become routine for gaining insights into the age of human fossils and the migrations of ancient humans.  相似文献

Abstract  

This paper primarily presents analyses from geophysical data and archaeological remains collected at one of a few known sites to the west of Lake Chad associated with fired-brick structures. It reports on previous fieldwork at the location, considers its alleged relationship with the early history of the Borno kingdom and then turns to present new data that provide fresh insights into the physical appearance, dating, material remains, economy and environment of the site. A brief discussion of the historical purpose of the fired-brick structures and the site itself concludes the paper.  相似文献
