Restriction fragment length polymorphism analysis of forensic science casework in the People's Republic of China.

Restriction fragment length polymorphism (RFLP) analysis for the purpose of individualization is now being used in casework in the People's Republic of China. This report describes the use of the multilocus minisatellite probe 33.15 to solve three cases, including two homicides and a rape. In the third case, fetal tissue was analyzed to prove that the alleged rapist was, in fact, the father. In each case, analysis of deoxyribonucleic acid (DNA) resulted in a positive match. The probability of chance association of the DNA fingerprint was calculated as 5.6 x 10(-12), which is similar to the figures reported in the literature.     

The individuality of fibres used to provide forensic evidence--not all blue polyesters are the same.

Fibres used in forensic casework suffer from a disadvantage common to other forms of trace evidence--it is not possible to state with absolute certainty that they originate from a specific source. Target fibre studies, population studies and research on 'blocks of colour' have effectively demonstrated the polymorphism of textile fibres (particularly man-made ones) and have shown that when a fibre is believed to have a specific putative source, the chance that it has originated from a different source purely by coincidence is extremely remote. A study by Houck MM (Houck MM, Inter-comparison of unrelated fibre evidence. Forensic Science International 2003; 135: 146-149) has shown that no coincidental matching fibres were recovered from items of clothing examined in 20 unrelated crimes. The study involved over two million comparisons. This work goes a step further, and using the example of blue polyester fibres shows that even within a very narrow segment of the whole general fibre population, many examples of a specific colour/type of man-made fibre taken from random sources can be compared and the chance of any two being the same is very low. These studies should help to show the specificity and value of transferred fibres in providing forensic evidence.     

The Trilateral cooperation

Legal context: The relatively informal agreements setting up the TrilateralCooperation (TC) among the world's three most important patentoffices are contrasted with formal multinational treaties suchas the Patent Law Treaty and the abortive Substantive PatentLaw Treaty. Key points: After its inception in 1983, the TC concentrated initially ondeveloping and implementing standards for electronic storageand retrieval of prior art documents, and facilitation of searching.This was later extended to electronic sharing of priority documentsand to standardization and searching of DNA sequence databases.More recently emphasis has been placed on harmonization of searchingand examination procedures, and working groups have comparedthe approaches of the Trilateral Offices (TOs) to the patentabilityof claims in areas of new technology. Encouragingly, the resultsare usually the same, although the specific objections raisedmay differ. The ultimate goal is to reach a situation in whicha claim allowed by one TO would be accepted by the others withoutfurther examination. Practical significance: The TC has already facilitated search and examination, leadingto lower costs and shorter pendency times than would otherwisebe the case. Further progress depends on harmonization of substantivepatent law, which in turn depends on the willingness of theUSA to accept a first-to-file system.     

IDENTIFYING THE PSYCHOLOGICAL FACTORS THAT MEDIATE THE ASSOCIATION BETWEEN PARENTING PRACTICES AND DELINQUENCY*

Past research has largely ignored the developmental changes within the child that account for the association between parenting and risk for delinquency. We used structural equation modeling and data from a longitudinal study of several hundred African‐American families to test the contentions of various theories regarding the sociocognitive and emotional factors that mediate the impact of parental behavior on a youth's risk for delinquency. Our findings largely supported the theories. The impact of monitoring/discipline was indirect through low self‐control and acceptance of deviant norms, whereas the effect of hostility/ rejection was indirect through low self‐control, hostile view of relationships, and acceptance of deviant norms. These two dimensions of parenting were no longer related either to affiliation with deviant peers or to conduct problems once the effects of these psychological characteristics were taken into account; the impact of these parenting practices was completely mediated by these four cognitive/affective variables. Contrary to expectation, however, these psychological factors did not mediate any of the relationship between caretaker involvement in antisocial behavior and child conduct problems.     

Failed States After 9/11: What Did We Know and What Have We Learned?

This paper addresses the relationship between accumulated knowledge and U.S. policy dealing with failed states and terrorism. The central thesis is threefold: (1) that more was known about the possible linkages between failing states and terrorism than appears in pre-9/11 U.S. policies; (2) that since 9/11 some important realignment of knowledge and practice has occurred, but it remains partial and incomplete; and (3) that new knowledge, especially about the policies to sustain and promote legitimate governance, needs to be generated in order to support an effective grand strategy for addressing the threats and challenges of the twenty-first century. The paper recommends such a grand strategy and, in addition to the required new knowledge, a significant reorganization of the U.S. national security policy-making apparatus. International studies curricula appear well suited for contributing to that new knowledge and the practitioners we require.
