Mitochondrial DNA control region variation in a population sample from Hong Kong, China

Entire mitochondrial control region sequences were generated from 377 unrelated individuals from urban Hong Kong. In line with other control region datasets from China, the sample from Hong Kong exhibited significant genetic diversity that was reflected in a random match probability of 0.19% and a mean pairwise difference of 13.14. A total of 305 haplotypes were identified, of which 262 were unique. These sequences will be made publicly available to serve as forensic mtDNA reference data for China.     

Genetic variation for 15 autosomal STR loci (PowerPlex 16) in a population sample from northern Greece

Fifteen autosomal STR loci were typed in a population sample of 318 unrelated individuals from northern Greece. Allele frequencies were determined, and Hardy-Weinberg equilibrium tested, for the following loci: D5S818, D7S820, TH01, TPOX, vWA, CSF1PO, D16S539, D13S317, D8S1179, D3S1358, FGA, PENTA D, PENTA E, D21S11, D18S51.     

Legal Decisions of Preadolescent and Adolescent Defendants: Predictors of Confessions,Pleas, Communication with Attorneys,and Appeals

While there is an increasing recognition that developmental differences may exist in legal decision-making, little research has examined this. This study examined the legal judgments of 152 defendants aged 11–17 (73 females, 79 males). Adolescents aged 15 and younger were more likely than older adolescents to confess and waive their right to counsel, and less likely to report that they would appeal their case or discuss disagreements with their attorneys. Also, while adolescents aged 15–17 were more likely to confess, plead guilty, and accept a plea bargain if they perceived that there was strong evidence against them, younger defendants’ legal decisions were not predicted by the strength of evidence. Importantly, defendants with poor legal abilities were more likely to waive legal protections, such as the right to counsel and to appeal. Defendants from below-average socioeconomic backgrounds were more likely to waive their interrogation rights, and defendants from ethnic minority groups were less likely to report that they would disclose information to their attorneys. The advice of attorneys, parents, and peers emerged as important predictors of plea decisions. None of the defendants reported that their parents advised them to assert the right to silence during police interrogation.     

The Impact of Nonprofit Collaboration in Early Child Care and Education on Management and Program Outcomes

The use of interorganizational relationships such as collaboration, partnerships, and alliances between public, private, and nonprofit organizations for the delivery of human services has increased. This article contributes to the growing body of knowledge on collaboration by exploring one kind of interorganizational relationship—interagency collaboration—in the field of early care and education. It examines variations within interagency collaborations and their impact on management and program outcomes. The findings show that interagency collaboration has a clear impact on management, program, and client outcomes: Specifically, the intensity of the collaborative relationship has a positive and statistically significant impact on staff compensation, staff turnover, and school readiness.     

Forensic handwriting examiners' expertise for signature comparison

This paper reports on the performance of forensic document examiners (FDEs) in a signature comparison task that was designed to address the issue of expertise. The opinions of FDEs regarding 150 genuine and simulated questioned signatures were compared with a control group of non-examiners' opinions. On the question of expertise, results showed that FDEs were statistically better than the control group at accurately determining the genuineness or non-genuineness of questioned signatures. The FDE group made errors (by calling a genuine signature simulated or by calling a simulated signature genuine) in 3.4% of their opinions while 19.3% of the control group's opinions were erroneous. The FDE group gave significantly more inconclusive opinions than the control group. Analysis of FDEs' responses showed that more correct opinions were expressed regarding simulated signatures and more inconclusive opinions were made on genuine signatures. Further, when the complexity of a signature was taken into account, FDEs made more correct opinions on high complexity signatures than on signatures of lower complexity. There was a wide range of skill amongst FDEs and no significant relationship was found between the number of years FDEs had been practicing and their correct, inconclusive and error rates.     

Age differences (or lack thereof) in discriminability for lineups and showups

Previous research reveals that showups are an inferior eyewitness identification procedure to lineups, but no single study has compared younger and older adults' identification decisions for both of these procedures. We had witnesses watch a mock crime video and then make an identification decision from a fair lineup, a biased lineup, or a showup that contained the perpetrator or a designated innocent suspect. Receiver operating characteristic (ROC) analysis showed that identification accuracy was higher from a lineup than from a showup for both age groups, even if the lineup was biased. In addition, calibration curves revealed that witnesses were underconfident when choosing from a fair lineup but overconfident when choosing from a showup. These results reinforce prior research asserting the superiority of lineups over showups.
