"Sexing" deoxyribonucleic acid (DNA) on DNA fingerprint gel: an internal control for DNA fingerprint evidence

Deoxyribonucleic acid (DNA) isolated from male and female fresh blood samples was processed exactly as for routine DNA fingerprint analysis; that is, the DNA was digested with particular restriction endonucleases and fractionated by agarose gel electrophoresis. Ultraviolet (UV) visualization of ethidium-bromide (EtBr)-stained gels revealed a sex-specific banding pattern, which depended only on the restriction enzyme used. By means of this test, which is based on direct detection of particular sex-specific restriction fragments in human DNA digests, the authors succeeded in determining the sex of DNA obtained from biological specimens recovered as criminal evidence in rape cases. The data obtained demonstrate that direct sexing of DNA on DNA fingerprint gel appears to be useful as an intermediate control step in DNA fingerprinting analysis used for the purpose of assailant identification.     

The transfer and persistence of trace particulates: experimental studies using clothing fabrics.

A series of experiments were conducted using various types of pollen grain, powder and metal particulates to determine their persistence on a range of different types of materials. The decay curves generated in the repeated experiments all broadly conform to those obtained and already presented in the literature for fibres and glass particulates. The experiments presented in this paper were conducted for up to 647 hours for individual runs and it was found that a general rule existed that it was the material type rather than the particulate type that was the major controlling factor in the persistence of particles. For the pollen grain experiments the overall theory is sustained; there is a significant loss initially followed by a slower decay although this is not precise given the varied nature of palynomorph types. The manner by which the particulates were introduced onto the material had an initial immediate effect, however, the persistence of these particulates over longer periods of time was generally unaffected.     

Law enforcement and civil society in Russia

Many Russian civil society organisations are directly engaging with state law enforcement agencies, particularly the police, in joint efforts to improve the performance and change the norms and values of state officials involved in administering justice. These activities are based upon a model of state–society relations that stresses the possibility of a positive relationship of mutual assistance and partnership between the state and civil society. Such assistance is often described by these organisations as helping low-level bureaucrats better perform their core organisational tasks. This model is contrasted with two alternative models of the role of civil society, which depict civil society either as teaching citizens the norms and values associated with liberal democracy, or as a potential counter-weight to an over-reaching state. Three cases studies of cooperation between NGOs and law enforcement agencies demonstrate the utility of such an approach. Although these projects suffer from some common pathologies of civil society work in Russia, they remain important, not least because of the presence of ‘uncivil society’ extremist groups who also are trying to influence the norms and beliefs of state law enforcement officials. The civil society activities profiled here suggest that direct, cooperative engagement with the state is one important component of long-term efforts to transform the Russian state in a more liberal, ‘civil’ direction.
