Y-chromosome STR haplotypes in Somalis

A total of 201 males from Somalia were typed for the Y-chromosome STRs DYS19, DYS385a/b, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 with the PowerPlex Y kit (Promega). A total of 96 different haplotypes were observed and the haplotype diversity was 0.9715. The number of unique haplotypes was 71 while the most common haplotype was observed 24 times.     

Y-chromosome STR haplotypes in Danes

A total of 185 unrelated Danish males were typed for the Y-chromosome STRs DYS19, DYS385a/b, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439 using the kits PowerPlex Y (Promega), ReliaGene Y-Plex 6 and ReliaGene Y-Plex 5 (Reliagene Technologies). A total of 163 different haplotypes were observed and among these, 144 haplotypes were unique. The gene diversity was 0.9985. In DYS392, a variant allele migrating as a 10.2 allele was observed. Sequencing of the allele showed a deletion upstream the repeated area.     

EMPOWERING CHILDREN IN MEDIATION

The available research in the mediation arena regarding child custody disputes indicates a lack of and growing need for effective intervention techniques. The authors present practicing mediators with a specific intervention model for interviewing, safeguarding, and empowering children in the process of mediating custody disputes. The mediation model utilizes a structured, strategic, and process-oriented approach with a family systems theoretical orientation and may be used in private or court-connected settings. The model presented here goes beyond the child-centered interview norm to the inclusion of the child in the process to assist parents in decision making. The model supports the current California statute under Family Code Section 3023, which states that "if a child is of sufficient age and capacity to reason so as to form an intelligent preference as to custody, the court shall consider and give due weight to the wishes of the child in making an award of custody or modification." The model does, however, maintain the position that the final decision continues to lie with the parents or the courts and not the child.     

Courts between Democracy and Hybrid Authoritarianism: Evidence from the Venezuelan Supreme Court

This article offers a theoretical discussion about courts in “hybrid regimes” that evolve from formerly democratic countries. The evolution toward authoritarianism typically allows governments more latitude to reduce judicial independence and judicial power. Yet, several reasons, including legitimacy costs, a tradition of using courts for judicial adjudication and social control, and even the use of courts for quenching dissent may discourage rulers from shutting down the judicial contestation arena and encourage them instead to appeal to less overbearing measures. This usually leads to a decline of the judiciary's proclivity to challenge the government, especially in salient cases. To illustrate these dynamics, I discuss the rise and fall of judicial power in Venezuela under Chávez's rule, focusing on the Constitutional Chamber of the Supreme Court. Formerly the most powerful institution in the country's history, the Chamber briefly emerged as an influential actor at the beginning of the regime, but a comprehensive intervention of the judiciary in 2004 further politicized the court and effectively reduced its policy‐making role.     

Visual detection of trace nitroaromatic explosive residue using photoluminescent metallole-containing polymers

The detection of trace explosives is important for forensic, military, and homeland security applications. Detection of widely used nitroaromatic explosives (trinitrotoluene [TNT], 2,4-dinitrotoluene [DNT], picric acid [PA]) was carried out using photoluminescent metallole-containing polymers. The method of detection is through the quenching of fluorescence of thin films of the polymer, prepared by spray coating organic solutions of the polymer, by the explosive analyte. Visual quenching of luminescence (lambda(em) approximately 400-510 nm) in the presence of the explosive is seen immediately upon illumination with near-UV light (lambda(ex)=360 nm). Detection limits were observed to be as low as 5 ng for TNT, 20 ng for DNT, and 5 ng for PA. In addition, experiments with normal production line explosives and their components show that this technology is also able to detect composition B, Pyrodex, and nitromethane. This method offers a convenient and sensitive method of detection of trace nitroaromatic explosive residue.
