Further studies on spot tests and microcrystal tests for identification of cocaine

The presence of cocaine in illicit drug samples is still being determined in some laboratories using spot tests and microcrystal tests. Seventeen chemical species were tested using three different spot tests (Wagner, Marquis, and cobalt thiocyanate followed by stannous chloride reactions) and two microcrystal tests (gold chloride and platinic chloride) to determine whether the results could be differentiated from the results of these tests on cocaine. The data obtained indicated that nine of the 17 compounds gave results similar to those from cocaine using the three spot tests, but that the results from microcrystal testing allowed for differentiation of all nine compounds from cocaine.     

Brazilian population database for the 13 STR loci of the AmpFlSTR Profiler Plus and Cofiler multiplex kits

Allele frequencies for the 13 STR core loci (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317, D7S820, CSF1PO, TPOX, THO1 and D16S539) included in the AmpFlSTR((R)) Profiler Plus and AmpFlSTR((R)) Cofiler kits were obtained for a sample of 700-800 genetically unrelated Brazilians. The expected performance of these loci for personal identification and paternity testing in the Brazilian population was estimated.

Environmental Concerns in Contemporary Brazil: An Insight into Some Theoretical and Societal Backgrounds (1970s–1990s)

This article intends to unveil some of the main theoretical backgrounds and current tendencies of environmental sociology in Brazil. But we are mainly interested in providing a historical reconstruction of the societal internalization of environmental concerns in Brazil, on both state and civic levels, with an emphasis on the transformations that took place over the 1970–1990s period. We argue that environmental civil associations do not find either a legal idiom or public forums by means of which they could turn their demands and moral concerns into a binding juridical code. This is so because, on the one hand, their moral concerns, even when based on de-traditionalized and abstract principles, are not paralleled with an autonomous legal framework, strong enough to set limits to the functioning of both the political-administrative apparatus as well as to economic actors. As we contend, this helps to explain why the environmental legislation in Brazil is rhetorically manipulated on a regular basis—and, hence, set aside whenever it contradicts other priorities. On the other hand, environmental concerns have always met with difficulties to become a priority in the Brazilian polity. Ultimately, our main goal is to carry out a critical consideration of the theoretical links that are widely set in the field of sociological theory between environmental concerns and modernity.     

Blood droplet dynamics--I

The interpretation of bloodstain patterns at crime scenes has received increased attention in recent years. Important to an understanding of this is knowledge of the fundamentals of blood droplet formation and impact dynamics. A review of the literature reveals that a considerable amount of work has been done with aqueous drop dynamics. Workers in the forensic science area seem to have been unaware of this. In addition, some of the most important and comprehensive early work with blood droplet dynamics seems to have been forgotten. It is not cited in more recent publications dealing with bloodstain pattern interpretation. This literature is reviewed and discussed as well. The present study presents results of experiments with blood droplet dynamics and high-speed photographs of blood droplet impacts on stationary target surfaces. Some longstanding misconceptions of importance to forensic scientists engaged in crime scene reconstruction are discussed.     

Managing Equality in Social Dilemmas: Emotional and Retributive Implications

The equality rule is an important coordination rule in symmetric public good dilemmas. Although prior research emphasized that people use the equality rule out of efficiency concerns (as it helps to obtain the public good in the most efficient manner among group members), it may also reflect a true preference for fairness. More precisely, research examining emotional and retributive reactions as a result of a violation of the equality rule by a fellow group member showed that equality indeed is related to people’s personal values and what they consider to be fair. The present paper suggests that a violation of the equality rule results in emotional reactions, and these emotional experiences encourage further retributive actions. The different reactions following an equality violation are described as a function of three features: (1) the motives to use equality, (2) attributions for explaining the violation, and (3) the honesty of the given explanation.

Mediation in Italy: Exploring the Contradictions

This article sets Italy in the context of three primary approaches to promoting mediation use in Europe: cultural, pragmatic, and legalistic. Despite the fact that Italy could be considered a "front-runner" in the latter category, the actual number of cases going to mediation to date has remained low. Drawing on both data from a recent CPR European Committee survey and aspects of the broader Italian legal and social context, this article explores reasons for this apparent contradiction and concludes by suggesting general principles that can be extrapolated from the Italian experience.
