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.     

Forensic casework analysis using the HVI/HVII mtDNA linear array assay

The mitochondrial hypervariable regions I and II have proven to be a useful target for analysis of forensic materials, in which the amount of DNA is limited or highly degraded. Conventional mitochondrial DNA (mtDNA) sequencing can be time-consuming and expensive, limitations that can be minimized using a faster and less expensive typing assay. We have evaluated the exclusion capacity of the linear array mtDNA HVI/HVII region-sequence typing assay (Roche Applied Science) in 16 forensic cases comprising 90 samples. Using the HVI/HVII mtDNA linear array, 56% of the samples were excluded and thus less than half of the samples require further sequencing due to a match or inconclusive results. Of all the samples that were excluded by sequence analysis, 79% could be excluded using the HVI/HVII linear array alone. Using the HVI/HVII mtDNA linear array assay, we demonstrate the potential to decrease sequencing efforts substantially and thereby reduce the cost and the turn-around time in casework analysis.     

Forensic Applications of the Miller Forensic Assessment of Symptoms Test (MFAST): Screening for Feigned Disorders in Competency to Stand Trial Evaluations

Forensic evaluations must systematically assess malingering and related response styles. In the criminal forensic domain, competency to stand trial evaluations are the most common referrals. Effective screens for feigned incompetency would be valuable assets for forensic evaluations. This study evaluates the effectiveness of the Miller Forensic Assessment of Symptoms Test (MFAST) as a screen for feigned incompetency. Using a simulation design, the MFAST was tested on jail and competency-restoration samples. Most notably, recommended MFAST cut score (6) was useful for the identification of feigning cases in competency evaluations. Recommendations for forensic practice, including the advantages and disadvantages of systematic screens, are discussed.     

Understanding rape and sexual assault: 20 years of progress and future directions

During the past 20 years, researchers have documented the widespread problem of rape in American society. Approximately one in four women are raped in their adult lifetime, which causes severe psychological distress and long-term physical health problems. The impact of sexual assault extends far beyond rape survivors as their family, friends, and significant others are also negatively affected. Moreover, those who help rape victims, such as rape victim advocates, therapists, as well as sexual assault researchers, can experience vicarious trauma. Future research and advocacy should focus on improving the community response to rape and the prevention of sexual assault.     

Age differences in eyewitness testimony

This study examined age differences in eyewitness testimony. Children, three and six years of age, and adults interacted with an unfamiliar man for 5 minutes. Four or five days later, the witnesses answered objective and suggestive questions, recalled what happened, and tried to identify the confederate from a target-present photo line-up. The adults and 6-year-olds did not differ in their ability to answer objective questions or identify the confederate, but 6-year-olds were more suggestible than adults and recalled less about the event. Compared to the older age groups, the 3-year-olds answered fewer objective questions correctly, recalled little about what happened, and identified the confederate less frequently. In addition, they were the most suggestible. The experiment extends our knowledge of children's ability to provide accurate eyewitness reports to a very young age group and to a situation in which participants are not merely bystander witnesses but instead directly interact with the confederate.     

Child care quality in different state policy contexts

Using data from the Child Care Supplement to the Fragile Families and Child Wellbeing Study, we test associations between the quality of child care and state child care policies. These data, which include observations of child care and interviews with care providers and mothers for 777 children across 14 states, allow for comparisons across a broader range of policy regimes and care settings than earlier research on this topic. Using multilevel linear and logistic models, we found that more generous subsidy policies (that is, greater investment, higher income eligibility) were positively associated with the quality of care in nonprofit child care centers, as well as with the use of center care. The stringency of regulations (that is, teacher education requirements, teacher‐child ratios/thresholds) was also associated with both quality and type of care, but in more complex ways. Higher teacher training requirements were positively associated with the quality of both family child care and nonprofit centers, while more stringent regulations decreased the number of children attending center care. No links were found between state policies and the quality of for‐profit center care. The implications for policy makers, advocates, and policy analysts are discussed. © 2007 by the Association for Public Policy Analysis and Management
