The application of isotope ratio mass spectrometry (IRMS) in forensic science to establish the provenance of a range of questioned substances including soils, drugs, explosives, currency, ivory and rhino horn has been widely documented. The present study wishes to highlight the applicability of IRMS and specifically stable carbon IRMS in determining the provenance of a carbonate rock that was switched for nickel metal exported from South Africa to Israel. The technique employed effectively argued against a South African origin for the rock whilst simultaneously supporting an Israeli origin, enabling investigators to focus their attention accordingly. The study represents the first documented instance known to the authors where IRMS has been employed in the forensic geo-location of a rock. 相似文献

Communication professionals are increasingly found within government ministries. Based on classic work on bureaucracy and recent literature on mediatization and personalization, this article develops two ideal types: the government information provider and government spin doctor. These ideals are constituted by six dimensions: recruitment criteria, values, loyalties, reputational concerns, interactions, and tasks. A study of nonpartisan communication professionals in Norwegian ministries is used to illustrate the empirical relevance of the ideal types. The analysis shows that for loyalties and reputational concerns, Norwegian communication professionals resemble the government information provider. Regarding interactions and tasks, they resemble the government spin doctor. For recruitment criteria and values, the picture is mixed. The empirical application thereby illustrates a fruitful aspect of the framework as certain configurations will bring forth inbuilt tension in communication professionals' role. The framework allows a fine-grained approach to extend ongoing debates of appropriate and inappropriate practices of communication professionals in ministries. 相似文献

The present paper provides an analysis of unfunded social securityas the outcome of a public decision making process in an endogenousgrowth economy. It employs a model in which there is a non-monotonic relationship beween productivity growth and the scale ofpublic intergenerational redistribution. The paper shows thatalthough unfunded social security need not harm growth in general,it is likely to harm growth in a democracy. This effect isreinforced by population aging. 相似文献

Population: Fifty healthy unrelated individuals were randomly chosen from each of the three populations viz., Bhargavas, Chaturvedies, and Brahmins. Three generation pedigree charts were prepared to ensure sirname endogamy in Bhargavas Chaturvedies and group endogamy in Brahmins subjects were chosen from several parts of Uttar Pradesh, a northern state of the Indian republic. 相似文献
