Practical applications of genotypic surveys for forensic STR testing

Legitimate genotype frequency estimation for multiallelic loci relies on component allele frequencies, as population surveys represent only a fraction of possible DNA profiles. Multilocus genotypes from two ethnic human populations, African American (n=195) and U.S. Caucasian (n=200), were compiled at 13 STR loci that are used worldwide in forensic investigation (D3S1358, vWA, FGA, D16S539, TH01, TPOX, CSF1PO, D8S1179, D21S11, D18S51, D5S818, D13S317, and D7S820). Sex-specific AmpFlSTR multiplexes provided stringent PCR-based STR typing specifically optimized for multicolor fluorescence detection. Heterozygosity at each STR locus ranged from 0.57 to 0.89 and encompassed from seven (TH01) to twenty-one (D21S11) alleles. Homozygosity tests, tests based on the distinct numbers of observed homozygous and heterozygous classes, log likelihood ratio tests, and exact tests assessed that the degree of divergence from theoretical Hardy-Weinberg proportions for all 13 STRs does not have practical consequence in genotype frequency estimation. Departures from linkage equilibrium, between loci, that imposed significance to forensic calculations were not indicated by observed variance of the number of heterozygous loci or Karlin interclass correlation tests. For forensic casework, reliable multilocus profile estimates may be obtained from the product of component genotype frequencies, each calculated through application of the Hardy-Weinberg equation to population database allele frequency estimates reported here. The average probability that two randomly selected, unrelated individuals possess an identical thirteen-locus DNA profile was one in 1.8x10(15) African Americans and one in 3.8x10(14) U.S. Caucasians.     

The Constitutional State and its Reform Requirements

In the first part, the author characterizes the fundamental contents (principles) of the constitutional state. In the second part, he describes the necessary reforms both at the level of the national constitutional state and at the global and humanity level. In the third part, he examines the methods and procedures of reform in the constitutional state, analysing: a) constitutional formation or complete revision; b) constitutional amendments or partial revision; c) parliamentary constitutional legislation; d) constitutional interpretation; e) government and non‐governmental “outlook” commissions. 1 Abstract by Giorgio Bongiovanni.
     

Developmental trends and gender differences in the relation between understanding of friendship and asociality

The relation between understanding of friendship and asociality was examined in 91 girls and 104 boys ranging in age from 9 to 17 years. Consistent with previous research, older children had higher understanding of friendship scores than younger children, and girls had higher understanding of friendship scores than boys. The relation between understanding of friendship and asociality was significant only for boys. Difficulty in understanding components of friendship appears to be one correlate of boys' delinquent tendencies.This article is based on the master's thesis of the first author, submitted to the University of Dayton.Received M.A. from University of Dayton.

Lessons learned from large-scale comparative dental analysis following the South Asian tsunami of 2004

The aim of this study was to examine the quality of the ante-(AM) and postmortem (PM) dental data that were submitted for entry into the PLASS data system in Phuket, Thailand, following the Boxing Day (December 26) Tsunami, 2004. The investigators were two forensic odontologists who were part of the New Zealand Disaster Victim Identification team that worked at Wat Yang Yao morgue and at the Information Management Center in Phuket. Our findings underline the usefulness of dental data in human identification, but point to a number of significant sources of error. Of the 78 PM records received, only 68% of radiographs and 49% of photos confirmed the accompanying dental charting. This underlines the value, particularly of photographs of the dental arches, in quality control. It also points to a large error component, which may have been due to inexperience of the operators, fatigue, poor conditions in the temporary morgue, or the problem of tooth-colored fillings. Of the 106 AM records received, 62% were of unacceptable quality and 64% were either not accompanied by radiographs or had poor quality radiographs. These results indicate that AM data collection ideally needs to be collated and checked by a forensically trained dentist(s) in the country of origin.     

Locus of control and sex offenders with an intellectual disability

Locus of control has been implicated as an important construct that is related to treatment outcome for several groups of offenders, including sexual offenders. However, little attention has been paid to how this construct is related to sexual offending by people with intellectual disabilities. Given this, 41 participants with intellectual disabilities were recruited into three groups: sex offenders who had undergone psychological treatment, sex offenders who had no history of treatment, and nonoffenders. All participants completed measures of locus of control and distorted cognitions. There was a significant difference between those who had and had not completed treatment in terms of cognitive distortions relating to sexual offending. There was no significant difference between the three groups on the measure of locus of control, with all three groups endorsing an external locus of control. Three possible explanations for how locus of control relates to sexual offending by people with intellectual disabilities is explored and discussed.
