Prisoners' expectations of the national forensic DNA database: surveillance and reconfiguration of individual rights

In this paper we aim to discuss how Portuguese prisoners know and what they feel about surveillance mechanisms related to the inclusion and deletion of the DNA profiles of convicted criminals in the national forensic database. Through a set of interviews with individuals currently imprisoned we focus on the ways this group perceives forensic DNA technologies. While the institutional and political discourses maintain that the restricted use and application of DNA profiles within the national forensic database protects individuals' rights, the prisoners claim that police misuse of such technologies potentially makes it difficult to escape from surveillance and acts as a mean of reinforcing the stigma of delinquency. The prisoners also argue that additional intensive and extensive use of surveillance devices might be more protective of their own individual rights and might possibly increase potential for exoneration.     

Why Muslims like democracy yet have so little of it

This paper explains the observed combination of relatively low levels of democracy and positive attitudes towards it in the Muslim world. It argues that this democracy paradox is understandable from the perspective of the principle of diminishing marginal utility: people value highly that of which they have little. This reasoning implies, however, that surveys like the World Values Surveys (WVS) elicit circumstance-driven marginal preferences rather than culturally determined attitudinal traits. Empirical evidence showing that individuals living in undemocratic societies have much more favorable inclinations towards democracy supports our argument.     

Jenseits von Zentrum und Peripherie

The central question for Karl Marx concerning the specific role of symbolic domination in capitalism challenges us down to the present day. We continue to improperly perceive the symbolic and immaterial structure subjacent to capitalism that is responsible for its peculiar ??symbolic violence.?? This article analyzes two interrelated issues: first, the racism implicated by concepts that articulate central and peripheral capitalism; and secondly, its principal consequence, which is the absence of broad and encompassing concepts in modern social theory. This eliminates a chance to articulate universal contexts??at least as universal as capitalism in its global expansion. The reach of contemporary critical theory is therefore limited in terms of central questions. Among the concepts that are abandoned by the fragmentation and contextualization is that of social class and that of the symbolic violence produced by structural changes that encompass capitalism as a whole. The following article draws on empirical studies concerning under class and the ??new?? middle class conducted in Brazil to illustrate its thesis.     

The International Movement of Prisoners

This article analyses and compares the evolution of the procedures and motivations for the international movement of prisoners under two systems operating in the United Kingdom ?C the inter-state prisoner transfer system and the international criminal justice enforcement system. It sets out the basic conditions for transfers under the current systems before outlining recent changes in the inter-state system to the requirement to obtain the consent of the proposed transferee (the prisoner) and the state that will implement the sentence. It proceeds to discuss the potential consequences and benefits these procedural modifications may entail for both systems. The paper concludes by evaluating the different and changing rationales used to justify the international movement of prisoners.     

Demystifying "oxi" cocaine: Chemical profiling analysis of a "new Brazilian drug" from Acre State

Recent information from various sources suggests that a new illicit drug, called "oxi", is being spread across Brazil. It would be used in the smoked form and it would look like to crack cocaine: usually small yellowish or light brown stones. As fully released in the media, "oxi" would differ from crack cocaine in the sense that crack would contain carbonate or bicarbonate salts whereas "oxi" would include the addition of calcium oxide and kerosene (or gasoline). In this context, this work presents a chemical profiling comparative study between "oxi" street samples seized by the Civil Police of the State of Acre (CP/AC) and samples associated with both international and interstate drug trafficking seized by the Brazilian Federal Police in Acre (FP/AC). The outcome of this work assisted Brazilian authorities to stop inaccurate and alarmist releases on this issue. It may be of good use by the forensic community in order to better understand matters in their efforts to guide local law enforcement agencies in case such claims reach the international illicit market.     

Comparison of methods to determine sex by evaluating the greater sciatic notch: Visual, angular and geometric morphometrics

Sex estimation is the first step for biological profile reconstruction of an unknown skeleton (archaeological or contemporary) and consequently for positive identification of skeletal remains recovered from forensic settings. Several tools have been developed using different osseous structures. With the intention to provide an objective method comparison, we reported the analysis of three different methods (visual, metric and geometric morphometrics) for sex assessment of the greater sciatic notch. One hundred and thirty pelvic bones (45.4% females and 54.6% males) from the National Autonomous University of Mexico Skeletal Collection pertaining to the contemporary Mexican population were analyzed. We used the ROC-analysis to test between desired false positive thresholds (1-specificity) and expected true positive rates (sensitivity) in order to predict the best approach to sex assessment. The comparison of the area under the ROC-curves shows significant differences among visual and metric methods. At the same time, the analysis suggested that higher morphological variation among the sexes is independent of the methodological approach. The results indicate that the metric (angle), with a high percent of indeterminate cases (34.6%), and visual, with 26.2% of the cases allocated as intermediate cases, were poorly accurate; we cannot recommend these techniques for sexing an unknown specimen. On the other hand, the geometric morphometrics approach improves sex estimation in 82.3% of correctly classified individuals with more than 95% of posterior probability. In addition to the method comparison, the major sexual variation of the greater sciatic notch was determined to be located on its posterior border.     

Challenging DNA: Assessment of a range of genotyping approaches for highly degraded forensic samples

It is common in forensic casework to encounter highly degraded DNA samples from a variety of sources. In this category bone and teeth samples are often the principal source of evidential material for criminal investigations or identification of long-deceased individuals. In these circumstances standard STRs are prone to fail due to their long amplicon sizes (since DNA becomes progressively more fragmented as it degrades). To successfully resolve such cases alternative markers can be used and until recently the only other tool available was mitochondrial DNA, which despite being more resistant to degradation, is much less informative. A rapidly developing approach to analyzing degraded DNA is the typing of loci from short-amplicon PCR products based on markers such as mini-STRs and autosomal SNPs. We have performed an analysis of several cases with naturally degraded DNA using established STRs plus mini-STRs and autosomal SNPs in order to make an objective comparison of the performance of each method using challenging DNA. The main aim was to establish the benefits and drawbacks of each marker set to help the practitioner choose the DNA analysis method most suited to the circumstances of each case.
