Evaluation of the composition of street cocaine seized in two regions of Brazil

This work evaluates cocaine purity and the concentration ranges of adulterants and inorganic constituents for 31 street cocaine samples seized in two different regions of Brazil from July 2008 to May 2010. Cocaine and adulterants, such as caffeine, lidocaine and benzocaine, were quantified by Gas chromatography–mass spectrometry (GC–MS), and the inorganic constituents were determined by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) and ion chromatography (IC). The cocaine concentrations in the samples seized in the Amazonas state (AM samples) ranged from 154 to 978 mg g^? 1, and these samples did not contain any of the adulterants studied. The cocaine concentrations in the samples seized in the Minas Gerais state (MG samples) ranged from 63.9 to 753 mg g^? 1. Caffeine was the main adulterant found in 76% of the MG samples, ranging in concentration from 5.5 to 645.3 mg g^? 1. Lidocaine was found in 66.7% of the MG samples, with concentrations ranging from 16.3 to 576.7 mg g^? 1. Benzocaine was found in only one MG sample, at a concentration of 84.8 mg g^? 1. Fourteen elements were identified by ICP-OES, and a wide variation was observed in the concentrations of Ca, Mg, Na, P, Al, Fe, Mn and Zn. Pearson Product–moment Correlations between the analytes allowed the constituents to be associated with the chemicals used in the manufacturing of cocaine and with some common diluents. The study of the purity of cocaine and the presence and concentration of adulterants and inorganic constituents is important because the latter can have deleterious effects on health.     

Resilience and Criminal Justice: Unsafe at Low Altitude

Resilience is increasingly featuring in crime and justice policy discussions. It appears in the fusion of military, security and criminal justice. It offers an alignment by which individual actors are to be adaptive to the uncertain conditions of high risk societies. This article unpacks the application of resilience to criminal justice to reveal at least one negative implication: by placing the focus on self-directed change resilient subjects have limited transformative power. The concept of resilience involves discounting a longer view that challenges the dominant social institutions and orders of neoliberalism. In contrast, we propose the dignified subject and the re-assertion of the discounted institutional context at a level above the individual and community. This analysis supports renewing the transformative agenda of a critical criminology.     

Rupture of liver cell adenoma with fatal massive hemoperitoneum resulting from minor road accident

Blunt abdominal trauma can cause rapid death resulting from serious injuries of internal organs. The liver is commonly involved and may show tearing, usually in its upper surface, resulting in hemoperitoneum eventually leading to death. Minor trauma implies serious liver damage only when previous pathologic changes causing enlargement of the organ are present. The case of a 25-year-old woman who died as a consequence of a minor road accident is reported. At autopsy, the body showed no external injuries, the only relevant finding being a massive hemoperitoneum from the rupture of an unusually large liver cell adenoma. Liver cell adenomas carry a serious risk of spontaneous rupture, which may result in the death of the patient. The occurrence of the rupture after a minor blunt abdominal trauma is highly unusual.     

Online reference database of European Y-chromosomal short tandem repeat (STR) haplotypes

The reference database of highly informative Y-chromosomal short tandem repeat (STR) haplotypes (YHRD), available online at http://ystr.charite.de, represents the largest collection of male-specific genetic profiles currently available for European populations. By September 2000, YHRD contained 4688 9-locus (so-called "minimal") haplotypes, 40% of which have been extended further to include two additional loci. Establishment of YHRD has been facilitated by the joint efforts of 31 forensic and anthropological institutions. All contributing laboratories have agreed to standardize their Y-STR haplotyping protocols and to participate in a quality assurance exercise prior to the inclusion of any data. In view of its collaborative character, and in order to put YHRD to its intended use, viz. the support of forensic caseworkers in their routine decision-making process, the database has been made publicly available via the Internet in February 2000. Online searches for complete or partial Y-STR haplotypes from evidentiary or non-probative material can be performed on a non-commercial basis, and yield observed haplotype counts as well as extrapolated population frequency estimates. In addition, the YHRD website provides information about the quality control test, genotyping protocols, haplotype formats and informativity, population genetic analysis, literature references, and a list of contact addresses of the contributing laboratories.     

Modeling Equilibrium Relationships: Error Correction Models with Strongly Autoregressive Data

Political scientists often argue that political processes movetogether in the long run. Examples include partisanship andgovernment approval, conflict and cooperation among countries,public policy sentiment and policy activity, economic evaluationsand economic conditions, and taxing and spending. Error correctionmodels and cointegrating relationships are often used to characterizethese equilibrium relationships and to test hypotheses aboutpolitical change. Typically the techniques used to estimateequilibrium relationships are based on the statistical assumptionthat the processes have permanent memory, implying that politicalexperiences cumulate. Yet many analysts have argued that thisis not a reasonable theoretical or statistical assumption formost political time series. In this paper I examine the consequencesof assuming permanent memory when data have long but not permanentmemory. I focus on two commonly used estimators: the Engle-Grangertwo-step estimator and generalized error correction. In my analysisI consider the important role of simultaneity and discuss implicationsfor the conclusions political scientists have drawn about thenature, even the existence, of equilibrium relationships betweenpolitical processes. I find that even small violations of thepermanent memory assumption can present substantial problemsfor inference on long-run relationships in situations that arelikely to be common in applied work in all fields and suggestways that analysts should proceed.
