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.     

Cultural dimensions of South African employees and internal organisational communication satisfaction

Abstract

This article aims to help communication practitioners know which cultural dimensions are associated with communication satisfaction. The meta-theoretical framework is the Excellence Theory of Public Relations and Communication Management (Dozier, Grunig and Grunig 1995, 35). The conceptual theoretical framework; cultural dimensions by Geert Hofstede (Hofstede and Hofstede 2005, 39) and communication satisfaction by Downs and Hazen (1977, 68) and Gray and Laidlaw (2004, 427) fit into the Excellence Theory of Public Relations and Communication Management. The research design was a quantitative survey with an online questionnaire as a data collection method distributed among a random sample. Validity was improved through pilot tests and the sampling technique. In terms of reliability this survey's scores sufficed as accurate and consistent, scoring above the acceptable score of 0.7 (Van Heerden 2001); 0.72 for national culture and 0.83 for communication satisfaction. Regression analysis was used to analyse the relationship between cultural dimensions (independent variables) and communication satisfaction (dependent variable). The findings clearly showed that national cultural dimensions have significant relationships with communication satisfaction. The implication was that internal communication practitioners could now be informed about the dynamics of the interaction between the cultural dimensions prevalent amongst South African employees and internal organisational communication satisfaction.     

Size doesn't matter: emotional content does not determine the size of objects in children's drawings

Abstract

In Experiment 1 we examined whether children spontaneously alter the size of objects in their drawings of emotionally-laden events. To do this, we evaluated children's drawings of their own personal, past experiences. Children were asked to draw a picture of an event that had made them happy and an event that had made them sad. We found no differences in the size of object that children drew in their positive and negative emotional events. In Experiment 2, we asked adults with and without clinical training to discriminate children's drawings of happy events from their drawings of sad events. There was no difference in the accuracy of raters as a function of clinical expertise. Moreover, performance for both groups was at chance when we removed drawings with specific emotional indicators from the set (e.g. smiles or tears). We conclude that the emotional interpretation of drawings on the basis of the size of objects in that drawing is fraught with difficulty. We question the projective use of drawings in forensic and clinical practice.
