KENT V. UNITED STATES SUPREME COURT JUVENILE CASE

As we went to press the decision was issued. Because of its significance the Journal will treat the case in two phases. The article that follows concerns itself with the facts and issues presented; the next issue will interpret the decision. This is the first time the U.S. Supreme Court has passed on the legality of juvenile court procedures.     

Isolation of deoxyribonucleic acid (DNA) from saliva and forensic science samples containing saliva.

Saliva and saliva-stained materials were examined as potential sources of deoxyribonucleic acid (DNA) for DNA analysis and identity testing. In this paper, the authors demonstrate that DNA was isolated and DNA banding patterns suitable for DNA typing were obtained from fresh saliva and various saliva-stained materials, such as envelopes, buccal swabs, gags, and cigarettes. Furthermore, DNA and DNA banding patterns were obtained from actual forensic evidentiary samples containing mixed saliva/semen stains. The DNA banding patterns obtained from saliva or saliva-stained material were indistinguishable from the patterns obtained from blood or hair from the same individual. Intact DNA was readily isolated and DNA banding patterns were obtained from saliva stored at -20 degrees C and dried saliva stains stored under varying conditions. We conclude that saliva and saliva-stained material can be good sources of DNA for analysis and for DNA typing in certain forensic settings.     

Human genotyposcopy: the identification of the species, sex and individual by DNA genetic imprints in a case connected with a murder attempt]

Blood stains on a knife were identified by DNA genotyposcopy. The statistical validation method has confirmed that the blood stains on material evidence belonged to the victim, the probability of random coincidence being less than 10(-11). The efficacy of using hypervariable locus-specific DNA probes and the possibility of detecting DNA impressions in blood stains stored for more than 3 months have been demonstrated.     

Pricing in the nuclear power industry: Public or private interest?

This paper tests empirically the Ramsey version of the public-interest theory of regulation by examining the pricing practices in the nuclear power industry, using a 1985 cross-sectional sample of 40 electric utilities. Other researchers have avoided this segment of the industry because of difficulties with nuclear fuel data, or perceived differences in the underlying production function. We show that regulators respond to political influences according to the Stigler-Peltzman version of regulation and that Ramsey pricing cannot be validated, at least for the nuclear segment of the electric power industry.     

The use of odontograms and panoramic roentgenography in personal identification]

Study of dental root surfaces prompted the authors to add to the routine odontogram 28 more maxillary surfaces and 22 mandibular surfaces, this making a total of 210 diagnostic signs. Employment of amplified panoramic roentgenography permitted the authors to detect specific features of the dental cavity, root canals, periodontal fissure structure, the presence of caries and its complications, inflammatory and systemic involvement, injury to the jaws and teeth. Visual examination of dental status and application of panoramic roentgenography will help improve forensic medical personal identification.     

A pathological study of sudden coronary death in China: report of 89 autopsy cases.

This paper reports the results of a forensic pathological study of 89 autopsy cases of Sudden Coronary Death (SCD). Of 89 cases, 63 (52 male, 11 female) were narrowed by 76-100% in cross-sectional area (XSA) of the coronary artery (CA) and 26 (22 male, 4 female), by 51-75%. Atherosclerotic plaques in the CA were serious and extensive, especially in the left anterior descending and often involved several branches of CA at the same time. Recent thrombosis was found in 18 cases, haemorrhage in plaques in 17 cases. Only 2 cases had visible acute myocardial infarction. Inflammatory cell infiltration was found in coronary plaques in 36 cases. Myocardial fibrosis or small scar formation was detected in 51 cases. It is suggested that although the incidence of coronary heart disease (CHD) is low in China, SCD is the commonest mode of Sudden Unexpected Death. The majority of SCD (52%) were middle aged males (30-49 years old). Most of the cases died suddenly during sleep without any clear precipitating factors. The characteristics of occurrence and pathological changes in the CA and myocardium and the pathological diagnosis of SCD are also analysed and discussed.     

Prevalence and distribution of premarital aggression among couples applying for a marriage license

This study used a modified version of the Conflict Tactics Scale to examine the prevalence of premarital aggression in a community sample of husbands and wives. The sample consisted of 625 couples participating in a longitudinal study of marital functioning and alcohol use. Consistent with past studies, the overall prevalence rate of husband-to-wife premarital aggression was 35%. Sociodemographic variables were associated with premarital aggression, with differences emerging primarily with regard to moderate aggression rather than mild aggression. Further, factors such as race, education, social class, cohabitation, and presence of children were independently associated with premarital aggression. This study is one of the first to examine premarital aggression in a large, heterogeneous sample of young husbands and wives at the same stage of relationship development. Future analyses will examine the prevalence, frequency, and continuity of husband and wife aggression over the first year of marriage.
