On the waves: a new kind of surf in Rio de Janeiro

Surfmen are thus called young daredevils who climb to the roof of suburban trains in Rio de Janeiro, Brazil and vie with each other in agility and prowess, some of them often falling on the railway tracks and being killed. The practice started as a need to hang on anything outside the crowded train and became a sport of sorts. Even though repressed by the railway authorities and punished by fines and imprisonment, the practice has been going on since the eighties and developed into a competition with rules, code of honour, grading of achievement. It became a means of improving self-esteem as well as securing leadership and social prestige by people who otherwise carry on lives devoid of any charm or ludic stimulus. A substitute behavior, it results from processes of cultural elaboration at work in the youth culture of our cities.     

Corporate citizenship and social responsibility in a globalized world

This article addresses the rise of corporate citizenship in the context of the changes in the nature of individual citizenship and the emergence of new, non‐territorial forms of national identity that are occurring in the current era of intensifying globalization. It also ponders the power of corporate citizens and the role they play in the prevailing global governance framework, as well as the extent to which they can behave responsibly and pursue sustainable development goals. More generally, the article discusses the limits to corporate social responsibility and the extent to which capitalism can be ‘caring’. The argument advanced is that, by virtue of their very nature, transnational corporations (TNCs) cannot become fully responsible and accountable citizens. Nonetheless, they can be induced to transform themselves in ways that may be compatible with socially and environmentally desirable objectives. Lastly, the article explores paths for action and, in particular, the potential of NGOs and anti‐globalization social movements to become civil regulators able to push for the introduction of binding rules and regulations and the construction a governance framework capable of restraining and harnessing the power of TNCs.     

Population genetics of nine short tandem repeat loci: allele frequency distribution in a Brazilian population sample

Gene and genotype frequencies in relation to the D3S1358, vWA, FGA, TH01, TPOX, CSF1PO, D5S818, D13S317, and D7S820 loci were determined in a sample of 290 unrelated individuals (204 Caucasians and 86 mulattoes) living in the city of S?o Paulo, Brazil. The sex test Amelogenin was also performed in all subjects from our sample, revealing the expected sex in all instances. Allele frequency data obtained from the analysis of these samples were in the usual range of other population groups with similar racial background. In the sample of Caucasian individuals, panmictic proportions were ruled out in relation to TPOX and CSF1PO loci, but only in the latter was the overall frequency of heterozygotes significantly less than expected. In the sample of mulattoes, Hardy-Weinberg proportions were rejected in relation to FGA and CSF1PO loci, but in no instance were the overall numbers of heterozygotes different from the corresponding expected ones under panmixia. Taking into account all this and also the number of tests performed, the degree of genetic heterogeneity of Brazilian populations, and the critical level reached by the significant results (1% < alpha<5%), the departures from panmixia here observed can be considered to be negligible in altering significantly biologic relationship odds calculated under the assumption of random matings.     

Mitochondrial DNA error prophylaxis: assessing the causes of errors in the GEP'02-03 proficiency testing trial

A qualitative and quantitative analytical method was developed and validated for the determination of 49 licit and illicit drugs in oral fluid. Small oral fluid samples, volume 1mL, were collected from volunteers using a modified Omni-Sal device and the analytes were extracted from an oral fluid/buffer mixture using a single Bond Elut Certify solid phase extraction cartridge. Liquid chromatography-tandem mass spectrometry (LC-MS-MS) and gas chromatography-repetitive full scan mass spectrometry (GC-MS) were used in parallel to analyze the extracts for the targeted drugs. Extracts were analyzed by GC-MS in their underivatized form and as their pentafluoropropionyl derivatives. Deuterated internal standards were used for quantification of drugs of abuse by LC-MS-MS to minimize matrix effects. Methadone-d(9) and tumoxetine were used as the internal standards for quantification of non-derivatized and derivatized analytes respectively by GC-MS. Linearity was demonstrated over the range 5-200 ng/mL and limits of detection were less than 4 ng/mL for each drug analyzed. The method demonstrated acceptable recoveries for most of the analytes and good intra- and inter-day precision. Acquisition of data by repetitive full scan GC-MS allows the addition of further analytes to the target menu.     

Interpretation of postmortem change in cadavers in Spain

Estimating time since death is especially difficult in the examination of poorly preserved cadavers and depends on the experience of the examiner and comparison with previously documented cases showing similar characteristics. The present study reports on information obtained over the past ten years through the work of the Laboratorio de Antropología y Odontología Forense (LAF) of the Instituto Anatómico Forense de Madrid, Spain, in particular evaluating how the type of fracture influences postmortem change. From the original 225 forensic cases examined between 1992 and 2002 in the LAF, a sample of 29 cases were selected from various regions of the Spanish mainland. A data collection protocol was established to reflect factors which the existing specialized literature, documenting the relation existing in the sample analyzed between time since death and the extent of postmortem change, which in the environments examined are distributed into the following phases: Phase 1 (putrefaction): one week to one month on the surface and two months in water. Phase 2 (initial skeletonization): two months on the surface and five to six months in water. Phase 3 (advanced skeltonization): six months to 1.5 years on the surface and 2.5 years buried. Phase 4 (complete skeletonization): about one year on the surface and three years buried. This paper also provide useful information on the impact of carrion insect activity, location, climate, seasonality, and predator.
