Multicenter evaluation of ultrafiltration, dialysis, and thermal coagulation as sample pretreatment methods for the colorimetric determination of paraquat in blood and tissues

Three methods of sample pretreatment for the rapid colorimetric determination of paraquat were compared: ultrafiltration, dialysis, and thermal coagulation. Spiked autopsy blood and tissue samples were examined in parallel in Groningen and Krakow and some samples were interchanged. All three methods gave recoveries between 87 to 102%; accuracy at the 20-mg/L level was within 10% of the target value and coefficients of variation in the 10 to 60-mg/L range were between 3 to 15%. Determinations in blood and liver in a fatal case of Gramoxone poisoning showed excellent agreement. Because of its reliability, speed, and simplicity, ultrafiltration is the method of choice.     

The Dutch Homo-Emancipation Policy and its Silencing Effects on Queer Muslims

The recent Dutch homo-emancipation policy has identified religious communities, particularly within migrant populations, as a core target group in which to make homosexuality more ‘speakable’. In this article we examine the paradoxical silencing tendencies of this ‘speaking out’ policy on queer Muslim organisations in the Netherlands. We undertake this analysis as the Dutch government is perhaps unique in developing an explicit ‘homo-emancipation’ policy and is often looked to as the model for sexuality politics and legal redress in relation to inequalities on the basis of sexual orientation. We highlight how the ‘speakability’ imperative in the Dutch homo-emancipation policy reproduces a paradigmatic, ‘homonormative’ model of an ‘out’ and ‘visible’ queer sexuality that has also come to be embedded in an anti-immigrant and specifically anti-Muslim discourse in the Netherlands. Drawing on the concept of habitus, particularly in the work of Gloria Wekker, we suggest that rather than relying on a ‘speakability’ policy model, queer Muslim sexualities need to be understood in a more nuanced and intersecting way that attends to their lived realities.     

The role of aggregation technologies in the provision of supranational public goods: A reconsideration of NATO??s strategies

Voluntary contributions to the provision of public goods do not necessarily follow a summation aggregation technology. The article investigates the alternative best-shot aggregation process and provides the corresponding Nash equilibrium conditions for allies in the context of joint products in a supranational alliance. The application deals with NATO over the period 1955–2006 and evidences new breakpoints and aggregation technology assessments, which leads to a reconsideration of the alliance’s strategy. We find that a best-shot technology prevails from 1955 to 1970. Afterwards, summation of contributions becomes the aggregation technology of the alliance, with increased strategic behavior after 1990.     

Age estimation by measurements of developing teeth: accuracy of Cameriere's method on a Brazilian sample

Developing teeth are commonly the criteria used for age estimation in children and young adults. The method developed by Cameriere et al. (Int J Legal Med 2006;120:49-52) is based on measures of teeth with open apex, and application of a formula, to estimate chronological age of children. The present study evaluated a sample of panoramic radiographs from Brazilian children from 5 to 15 years of age, to evaluate the accuracy of the method proposed by Cameriere et al. The results has proven the system reliable for age estimation, with a median residual error of -0.014 years between chronological and estimated ages (p = 0.603). There was a slight tendency to overestimate the ages of 5-10 years and underestimate the ages of 11-15 years.     

High resolution Y chromosome typing: 19 STRs amplified in three multiplex reactions

Nineteen Y-specific short tandem repeat (STR) loci have been amplified in 768 samples from the Iberian Peninsula in order to evaluate their usefulness in forensic casework. Two previously published multiplex reactions by Thomas et al. [Hum. Genet. 6 (1999) 577] (MS1, modified here: DYS19, DYS388, DYS390, DYS391, DYS392 and DYS393) and by Ayub et al. [Nucl. Acids Res. 28 (2000) e8] (CTS: DYS434, DYS435, DYS436, DYS437, DYS438 and DYS439) plus a novel one reported here (EBF: DYS385, DYS389, DYS460, DYS461, DYS462 and amelogenin) have been used. DYS385, DYS439 and DYS391 were the most informative loci with allele diversities of 0.7997, 0.6683 and 0.5940, respectively. A total of 635 different haplotypes were observed, of which 573 (90.24%) were found in single individuals. The overall haplotype diversity was 0.9988 and that obtained by each multiplex system was 0.9812 for EBF, 0.9292 for MS1 and 0.9089 for CTS.     

Fingermark Evidence Evaluation Based on Automated Fingerprint Identification System Matching Scores: The Effect of Different Types of Conditioning on Likelihood Ratios

In recent studies, the evidential value of the similarity of minutiae configurations of fingermarks and fingerprints, for example expressed by automated fingerprint identification systems (AFIS), is determined by likelihood ratios (LRs). The paper explores whether there is an effect on LRs if conditioning takes place on specified fingers, fingerprints, or fingermarks under competing hypotheses: In addition, an approach is explored where conditioning is asymmetric. Comparisons between fingerprints and simulated fingermarks with eight minutiae are performed to produce similarity score distributions for each type of conditioning, given a fixed AFIS matching algorithm. Both similarity scores and LRs are significantly different if the conditioning changes. Given a common‐source scenario, “LRs” resulting from asymmetric conditioning are on average higher. The difference may reach a factor of 2000. As conditioning on a suspect's finger(print) is labor‐intensive and requires a cooperating suspect, it is recommended to just condition on the number of minutiae in the fingermark.
