Electrical and thermal injuries in pig skin — Evaluated and compared by light microscopy

The morphology of pig skin after electrical (el) and thermal exposure was studied in order to find methods applicable for disclosing electrical torture.Biopsies from pig skin exposed 24 hours earlier to either heat or electrical current under general anesthesia were studied by light microscopy. The amount of energy used of either type ranged from about 6 to about 100 joule deposited on two circular areas of the skin measuring 12 mm in diameter.In sections stained with hematoxylin and eosin alterations were found in heat-influenced specimens following the administration of moderate and large doses of energy. Changes were observed in el-influenced specimens also after the administration of low amounts of energy, which did not lead to macroscopical changes in the skin. The two types of energy induced different patterns of alterations inside the epidermis. The most characteristic change following heat exposure was the presence of a granular or fibrillar eosinophilic cytoplasm and subepidermal clefts, while el-expoure often produced white homogeneous cytoplasm and shadowy nuclei (“white necrosis”) in the attached epidermis. The individual changes could be produced by both types of injury, but to a highly different degree. However, the alteration classified as “vesicular nuclei” was only observed in el-damaged skin. The dermis from the more severely injured skin of both groups showed a homogeneous appearance (“necrosis”). While the changes of epidermis and dermis in response to heat were diffusely distributed, the changes created by electrical injury were often present in segments. By electrical damage homogeneous areas with loss of stainability and shadowy nuclei were occasionally observed in sweat glands, hair sheaths and in vessel walls, structures which are suggested to serve as conductors for the electrical current. “Vesicular nuclei” were observed in similar structures.Some of the findings may be associated with differences in intensity of energy during exposure to heat and electricity. Furthermore, the existence of different biological patterns following the two types of exposure should be considered. The studies are being continued to elucidate these basic questions, and to study further the medical diagnostic potential of examining skin biopsies from tortured individuals.     

Protecting Local Governments from Arbitrary State and Federal Interference: What Prospects for the 1990s?

The number of local governments in Nigeria has been fixed at453 by the 1989 Constitution. The key purpose of this provisionis to prevent state governments from creating local governmentsand altering local-government boundaries for political purposes.The provision is part of a larger program of localgovernmentreform undertaken by the federal military government to ensurethe integrity and autonomy of democratically elected local governmentsunder the Third Republic. States are limited in their abilityto intervene in local government affairs, and the federal governmenthas certain direct powers and responsibilities for local governments.Whether these reforms will achieve their intended objectives,however, is arguable.     

Intergovernmental Management: Federal Changes, State Responses, and New State Initiatives

This article surveys state responses and new state initiativesin 1983 to three sets of successive federal changes in domesticpolicy. Collectively referred to as the New Federalism, thesechanges include the block grants and accompanying regulatoryreforms of 1981, the changes in Medicaid reimbursement policyof 1982, and the job training and development programs of late1982 and early 1983. Following a brief overview of these changesin intergovernmental management perspective, state responsesin 1983 are examined in three areas—policy development,policy and program management, and service delivery management.     

The Effects of Democracy on Economic Growth and Inequality: A review

What effects does political democracy have on such development outcomes as economic growth and socioeconomic equality? Competing theoretical models have been proposed that represent each of the possibilities: democracy as facilitating development, democracy as a hindrance to development, and democracy as bearing no independent relationship to development outcomes. Each of these theoretical models is explicated and, then, the evidence from quantitative, cross-national tests of the effects is reviewed. Overall, the evidence provided by the approximately dozen studies for each outcome yields few robust conclusions with respect to the theoretical models. To guide in the evaluation of the evidence, the studies are in turn distinguished by such design characteristics as sample, period observed, measures used, and form of relationship specified. This procedure, while it does not produce definitive support for any of the models, does assist in interpreting the results of past research as well as generating fertile guidelines for future research.
