The Effect of a Standard to Improve Person Descriptions by Children

This study examines whether or not using a person as a standard/comparison improves the ability of a child witness to provide more accurate detail about a previously observed person. Study participants included 135 children who observed a male stranger and were then later asked to describe and answer various questions about that person using a third-person standard/comparison. Despite the fact that one-half of participants were exposed to a standard/comparison, neither participants’ gender or exposure to the standard/comparison improved recollection outcomes. However, the gender of the standard/comparisons - especially where female - did have a significant effect on the recall ability of male participants.     

Case law of the EPO Boards of Appeal in 2006

Legal context: The article reviews significant decisions handed down by theBoards of Appeal of the European Patent Office (EPO) in 2006,concentrating on decisions of the Enlarged Board and the Boardsof Appeal issued in 2006 and published or to be published inthe OJ EPO. Key points: The article discusses the application of Art. 24 EPC on exclusionand objection to members of the boards of appeal in the lightof the following decisions: G 1/05, T 281/03 and J 15/04; referralspending before the EBA on the subject of divisional applications(Art. 76 EPC and R. 25 EPC) and exclusion from patentabilityunder R. 23d(c) in conjunction with Art. 53a EPC; and decisionsof technical boards of appeal on exclusions from patentability(Arts. 52 (2)(3) and (4) EPC), the requirement of industrialapplicability (Art. 57 EPC) and re-establishment of rights (Art.122 EPC). Practical significance: The article provides an overview of the 2006 case law of theboards of appeal which is particularly useful since most ofthe decisions discussed have not yet been published in the OJEPO. The author is critical of the recent case law on the applicationof Art. 24 EPC (exclusion and objection to members of the boardsof appeal) and reports on several decisions of particular legalinterest.     

Violent victimization among males and economic conditions

Research Summary In this article, we use data from the 1973 to 2005 National Crime Victimization Survey (NCVS) to estimate previously unknown trends in serious nonfatal violent victimization for Latino, non-Latino Black, and non-Latino White males in the United States. Past research has shown that Blacks and Latinos have been more susceptible than Whites to financial hardship during economic downturns and that economic disadvantage is an important correlate of violence in cross-sectional analyses. If significant declines in the national economy contribute to increases in violence, then crime trends disaggregated by race and ethnicity should show greater changes among minorities during periods of economic downturn. Although rates of violence have declined for all groups, we find that trends for Latino and Black males are similar and closely follow changes in consumer sentiment. In contrast, trends for White males display fewer fluctuations coinciding with changes in economic conditions. Continued disaggregation shows that these patterns appear primarily in stranger violence and not in violence by known offenders. The patterns also suggest that the association between changing economic conditions and male victimization trends might have weakened in recent years. Policy Implications The findings raise concerns about the potential impact of recent economic changes on the risk for serious victimization, particularly among Blacks and Latinos. In light of the possible recent weakening of the relationship between economic changes and crime, future research should assess whether criminal justice policies and other factors moderate the relationship between economic conditions and victimization and use group-specific measures of violence so that important variability across race and ethnicity is not masked. These analyses also should be expanded to consider the potential effects on violence of government policies designed to alleviate poverty and unemployment.     

Characterization of human DNA in environmental samples

Environmental samples from indoor surfaces can be confounded by dust, which is composed largely of human skin cells and has been documented to contain roughly tens of micrograms of total DNA per gram of dust. This study complements previous published work by providing estimates of the quantity of amplifiable human DNA found in environmental samples from a typical indoor environment, categorized by the intensity of human traffic and visible quantity of dust. Dust was collected by surface swabbing standard 576 cm² areas in eight locations, and evaluated for total DNA quantity, presence of human DNA (mitochondrial and nuclear loci using conventional PCR), quantity of human nuclear DNA using quantitative PCR, and STR analysis. The total DNA content of 36 dust samples ranged from 9 to 28 ng/cm², and contained 0.2–1.1 pg/cm² of human DNA. Overall, human DNA was detected in 97% of 36 dust samples and 61% of samples yielded allele distributions of varying degrees of complexity when subjected to STR analysis. The implications of this study are twofold. First, the presence of dust in evidence can be a significant contamination source in forensic investigations because the human DNA component is of sufficient quality and quantity to produce allele calls in STR analysis. This can be effectively managed by implementing stringent protocols for collection and analysis of potential biological samples. A second implication is the use of dust as a source of evidence for identification of inhabitants within a defined location. In the latter case, a number of additional studies would be necessary to identify relevant pretreatments for environmental dust samples and to develop the necessary deconvolution techniques to separate the composite genotypes obtained.
