The recovery of latent fingermarks and DNA using a silicone-based casting material

There are many techniques available for the recovery of fingermarks at scenes of crime including the possibility of taking casts of the marks. Casts can be advantageous in cases where other destructive recovery techniques might not be suitable, such as when recovering finger marks deposited on valued or immobile items. In this research, Isomark (a silicone-based casting material) was used to recover casts of finger marks placed on a variety of substrates. Casts were enhanced using cyanoacrylate fuming. Good quality marks were successfully recovered from a range of smooth, non-porous surfaces. Recovery from semi-porous surfaces was shown to be inefficient. DNA was subsequently extracted from the casts using QIAamp Mini extraction kits, amplified and profiled. Full DNA profiles were obtained 34% of samples extracted.     

Child Medical Evaluation Program: a statewide system for the medical and mental health evaluation of abused and neglected children

The Child Medical Evaluation Program examines 1500 children per year suspected by county social service departments of having subtle physical evidence of abuse or neglect. The program utilizes private practitioners, primarily pediatricians, in a systematic manner and provides consultation, direction, and quality control. The system is a unique, cooperative effort between private practitioners and county departments of social service. It is administered from a state university department of pediatrics. The cost is low, government involvement minimal, and the service extensive. The system is recommended to other states.     

Male and female reasoning biases and offending behavior

Although the majority of the general population decides not to offend, a significant proportion decides otherwise. The research presented in this article explores whether offenders reason in manners that are comparable with a non-offender population, or if their decision to offend may be a consequence of inappropriate reasoning strategies. Psychologists have observed systematic deviations from logical predictions of reasoning behavior on a variety of tasks and that content specific information can have marked effects on reasoning behavior. Established reasoning tasks were adapted for use in a crime specific context to examine whether such biases were apparent in an offender population. Moreover, given a paucity of research into gender differences, the research conducted balanced for gender in a methodologically rigorous design. Data suggested that reasoning biases found with non-offender populations extended to an offender population and some interactions by gender and by offender group were noted. Implications of the results are discussed with suggestions on how the research may be extended and implications for policy.     

A rapid method for the determination of cocaine in brain tissue.

A rapid procedure is described for the extraction and analysis of brain samples for cocaine and benzoylecgonine. Human brain tissue was sectioned at autopsy, and samples were subjected to a lipase digestion, subsequent to solid-phase extraction. The distribution of cocaine and benzoylecgonine throughout different regions of the brain was determined by high-performance liquid chromatography.     

On National Self-determination

This paper argues in favour of a conception of self-determination which involves the equal recognition of different national identities. It proceeds by, first, criticizing the dominant territorial (in contrast to national) conception of self-determination. It then addresses three main criticisms of a principle of national self-determination. These are (1) the argument from indeterminacy; (2) the argument from instability; (3) the problem of overlapping nationalities.
