A comparison of mediated and non-mediated juvenile offender cases in California

Juvenile delinquency is a major public concern in the United States, and increasingly in many other industrialized countries. The last few years have seen a decline in officially recorded juvenile delinquency (Snyder, 1997). However, projections are that with the anticipated increase of the U.S. teenage population because of the echo baby boom generation, serious juvenile crime will substantially increase in the next few years (see Fox, 1996).     

Sensitivity enhancement of ninhydrin-treated latent fingerprints by enzymes and metal salts

Lyophilized Sigma Type III trypsin has been applied to latent prints two weeks to two months old. This trypsin preparation eliminates the background problems that had been encountered with old prints in a previous study. Zinc chloride treatment of latent prints previously exposed to ninhydrin enhances their detectability upon laser examination. However, it has been reported that the zinc chloride reaction occasionally fails to occur. Accordingly, we have investigated the optimization of this reaction. We find that high humidity and elevated temperature, particularly the former, are needed. Cadmium nitrate, although it produces weaker fluorescence than zinc chloride, may at times be useful. Reaction conditions are much the same as those for zinc chloride.     

Filicidal abuse in the histories of 15 condemned murderers

This paper describes the family characteristics of 15 Death Row inmates. It documents extraordinary physical and/or sexual abuse in 13 cases. It describes murderous behaviors of parents toward children in 8 cases and documents ongoing hostility and neglect throughout childhood and adulthood. The paper explores the mechanisms by which such abuse may contribute to violent behaviors. It highlights the relevance of these findings to the outcome of sentencing in capital cases.     

Acute effects of carbon monoxide and cyanide on hepatic mitochondrial function

The effects of carbon monoxide and cyanide on the hepatic redox state and energy charge were investigated. Rats were used for the experiment under pentobarbital anesthesia. Immediately after laparotomy, a rat was placed in an animal chamber made of a transparent plastic box and exposed to a test gas for 3 min. Every test gas was produced in a gas chamber connected to the animal chamber with a flexible tube. HCN was produced from NaCN and H2SO4. In the CO inhalation experiment, various amounts of CO were introduced into the gas chamber. Immediately after an exposure, about 2 g liver was frozen in situ with a precooled clamp. Oozed blood from the wound surface was sampled. Concentrations of ATP, ADP, AMP, acetoacetate, and beta-hydroxybutyrate in hepatic mitochondria were determined, and the redox state and the energy charge were calculated. For cyanide as well as CO, significant negative correlations were found between the concentration in the blood and the redox state. The same held true for the energy charge. The redox state showed a slight increase at low concentrations of both gases; however, thereafter it began to decrease sharply with increases in concentrations. When concentrations of the toxicant in the blood reached certain levels, a kind of turning point, beyond which the redox state does not decrease any more, was observed. It was about 40% for HbCO and about 2.0 micrograms/ml for cyanide, and the points seemed to be related to the concentrations, beyond which cells are irreversibly damaged. On the other hand, the energy charge did not change at low concentrations. With an increase in toxicant concentrations, the energy charge decreased drastically. The rate of decrease in the energy charge became higher when blood concentrations exceeded certain levels. It was about 40% for HbCO and 2.0 micrograms/ml for cyanide. The presence of low levels of blood cyanide did not affect the relationship between the energy charge and the HbCO concentration.     

Police training in ethics: The need for an innovative approach in mandated programs

Instruction in ethics is included in state-mandated basic training programs in almost all states in America. A review of the relevant literature showed that the courses on police ethics need to highlight adherence to the higher values of law, cultivation of principled conduct, and personal integrity. Based on the examination of the core elements of the currently mandated ethics courses, it was observed that these recompendations are not generally taken into account in the preparation of the courses on ethics.
