Never say never. Negligible carboxyhemoglobin in the victim of a smoldering mattress fire

For many years, a high blood carboxyhemoglobin concentration has been used as a criterion for determining that a victim of conflagration was alive in the fire. We report a case in which a man died from the combined effects of burns and hypertensive cardiovascular disease. He had a negligible blood carboxyhemoglobin concentration, but the environmental evidence and autopsy findings are indicative of life in the fire, which arose in a smoldering mattress. We conclude that uncritical, rigid adherence to the requirement that fire victims have high carboxyhemoglobin concentrations can be misleading.     

Can Mercosur Survive? Domestic and International Constraints on Mercosur

Mercosur has survived several crises by resorting to presidential diplomacy, but it risks becoming an empty shell unless member states work to coordinate macroeconomic policies. Its survival depends on the outcome of domestic political struggles in Brazil and Argentina and on the harmonization of exchange-rate policies between the two countries. This article examines the Argentine-Brazilian "trade wars" provoked by successive devaluations of the Brazilian currency, aggravated in 2001 by the Argentine economic crisis. The social explosion in Argentina in December 2001 showed that domestic actors can successfully challenge proglobalization policies. To consolidate, Mercosur will have to address the democratic deficit while building supranational institutions and an effective dispute-settlement system.     

Self-esteem in early adolescence: The identification and prediction of contrasting longitudinal trajectories

The present study focused on differences in self-esteem trajectory in early adolescence rather than on average change across all children. Longitudinal data from 128 adolescents were obtained over a 2-year period that encompassed the transition from elementary school to junior high school. Cluster analysis revealed four markedly divergent self-esteem trajectories: consistently high (35%), chronically low (13%), steeply declining (21%), and small increase (31%). Attempts to predict trajectories were only partially successful. Peer social support was the strongest predictor, but its relation to self-esteem appears more circumscribed than had been thought. The discussion considers differences in the experience of early adolescence, as well as implications for the design and evaluation of preventive intervention.Funding for this research was provided via awards to Barton J. Hirsch from the National Institute of Mental health (New Investigator Research Award in Prevention), the University of Illinois Research Board, and the Northwestern University Research Grants Committee. Abbreviated versions of this article were presented at the meetings of the Society for Research on Adolescence, Alexandria, Virginia, March 1988, and the Society for Research in Child Development, Kansas City, April 1989.

Research interests include community psychology, ecology of adolescent development, social networks, and social policy.Research interests include peer relations and school-based preventive intervention.     

Commotio cordis as a result of a fight: report of a case considered to be imprudent homicide

The report describes a fatal outcome in a 5-year-old male who died after drinking a fatal dose of ethanol at the party held by his parents. Urine and blood alcohol level of the deceased was 0.4 and 0.5 g/dL, what might explain the sudden death of the child. In addition, the analysis of the boy's hair demonstrated the presence of ethyl glucuronide (EtG), a marker of alcohol consumption; hair EtG concentration levels indicated that the boy might have occasionally imbibed alcohol prior to death. Pathological lesions of the liver observed in histopathology did not contradict such a hypothesis.     

Spatial mobility of knowledge transfer and absorptive capacity: analysis and measurement of the impact within the geoeconomic space

This paper analyses the spatial mobility of knowledge and technology transfer and measures the economic impact on the geo-economic space. The data of laboratories operating in different research and technological fields are used. The results show that, when the distance from the source of knowledge (research institute) to users increases, the impact of knowledge and technology transfer decreases with damped pulsations. The magnitude of knowledge and technology transfer shows a high intensity within the industrial district because small businesses are able to acquire externally scientific knowledge, without conducting in-house research, but by interactions with public scientific bodies and adopting both collective rules that act as collective knowledge devices, making collective learning possible, and skilled labor.
