Research on the use of municipal corporations to deliver local and regional public services has evolved significantly in the past decade. Most of this work addresses the performance of this service-delivery mode in relation to local bureaucracies. However, much less is known about the drivers for the adoption of municipal corporations in the first place. This article reviews the main determinants of adoption – service characteristics, institutional and regulatory settings, political constraints and financial conditions – and highlights the need for comparative research across countries. 相似文献

The authors evaluated the usefulness of the postmortem biochemical analysis of ionic ratios in different parts of the heart and their relation to cardiac damage caused by chest trauma, as observed by anatomopathologic study. Fifty-nine 59 cases were studied, selected from routine necropsies, and samples were taken from different sites of cardiac tissue. The cause of death was trauma in 40 cases and nontraumatic causes in 19 cases. The object of this study was to analyze the levels of Na+, K+, Ca+2, Mg+2, and Zn+2 in different zones of the heart, and the relationship between intracellular and extracellular ion ratios and the different causes of death and any anatomopathologic alterations observed. The biochemical tests revealed a possible relation between the ionic values and cause of death. Alterations in cell membrane permeability and corresponding modification of the ionic ratios were produced earlier than histologic alterations, which need longer to establish themselves whether or not they follow a traumatic process. 相似文献
