Early epidermal changes in heat- and electrically injured pig skin. I. A light microscopic study

In order to find methods applicable for disclosing electrical torture, pig skin was exposed to heat and electricity under controlled circumstances. Biopsies were obtained immediately after exposure and the morphology of the heat lesions was compared to that of electrical lesions. The cytoplasm of epidermal cells in heat lesions appeared granular or fibrillar, while the nuclei were rather unaffected. In electrical lesions the cytoplasm appeared homogeneous often with a peculiar white colour in hematoxylin-eosin stained sections. The nuclei were either dark and shadowy or enlarged and vesicular. The keratin in electrical lesions often showed a bright yellow colour. Small defects in the epidermis were seen in some electrical lesions. Thus the morphology of electrical lesions differed markedly from that of heat lesions. Although some of these differences may be due to differences in distribution and intensity of energy, it is probable that pH shifts in the cells due to electrolysis is the main cause of the specific morphology of electrical lesions.     

Funding the Cause: How Public Interest Law Organizations Fund Their Activities and Why It Matters for Social Change

Most of the work of public interest law organizations does not make money. How do these organizations survive, given the economic realities of law practice? Drawing on survey data from a national random sample of public interest law firms, we investigate how funding models vary across public interest organizations and how funding sources affect these organizations’ activities. We find funding structures have, over time, shifted away from foundation support toward government grants. Compared to other organizations, however, conservative organizations draw significantly less of their budget from federal and state grants, and significantly more of their budget from private contributions. Conservative organizations are significantly less likely than other organizations to rely on funding that prohibits engaging in class actions, receiving attorney's fees, or lobbying. Respondents reported that funding restrictions hamper their ability to negotiate favorable settlements, bring about systemic change, and represent vulnerable client communities. We close with a comparative institutional analysis of different funding models.     

Public Interest Law Organizations and the Two‐Tier System of Access to Justice in the United States

Public interest law organizations (PILOs) are important institutions for providing access to justice in the United States. How have political, economic, and institutional factors shaped PILOs? How do PILOs vary in the services they offer and in their geographical location relative to poverty and population in the United States? This article investigates these questions by combining original survey data from a representative sample of public interest law organizations with GIS data on population and poverty. We find that the presence of a PILO is positively related to political progressiveness and population at the county level, but negatively related to the concentration of poverty. Our analysis reveals a two‐tier system of public interest representation in which national organizations engage in a variety of social change strategies, whereas local and regional organizations utilize more limited strategies and depend more on governmental funding. These patterns have implications for access to justice in the United States today.     

An actor‐oriented approach for strengthening research and development capabilities in natural resource systems

This article is concerned with strengthening research and development capabilities in natural resource systems, especially systems oriented towards reducing rural poverty. It reviews current planning, monitoring and evaluation (PME) literature and identifies five major areas of concern: (1) the lack of systematic and usable methods for qualitative assessment; (2) the narrow focus of current activities; (3) the failure to address the political nature of evaluations; (4) the lack of integration of PME methods with the practice of research and development; (5) the need for methods that facilitate flexibility, learning and replanning in process projects. Major new approaches for PME in process projects are reviewed and some gaps are identified. The article develops an ‘actor oriented approach’ for strengthening research and development (R&D) capabilities in natural resource systems. This holistic approach identifies major actors in an overall R&D system and concentrates on the determinants of flows of information between actors. Two major tools are presented: an actor linkage matrix and a determinants' diagram. The use of these tools is illustrated with a retrospective case study from the Kavango region of Namibia, and the potential strengths and weaknesses of the approach are discussed.

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.     

Tracing the use of electrical torture

With the aim of being able to trace skin sequelae to electrical torture, an interdisciplinary group of scientists (the "electrical group" of Anti-Torture Research, ATR) has performed controlled morphological studies on skin biopsies from experiments with fully anesthetized pigs. "Vesicular nuclei" in epidermis and a characteristic pattern of collagen calcification in dermis were found to be typical of electrical damage. These alterations were produced by alternating current as well as by direct current.
