A new individualization marker of semen: deoxyribonuclease I (DNase I) polymorphism.

We describe a method for obtaining specific and reproducible deoxyribonuclease I (DNase I) typing from liquid semen. Isoelectric focusing of the enzymes on polyacrylamide gel (IEF-PAGE, pH 3.5-5) was accomplished using a 0.5-mm thick gel. The separated isozymes were visualized by a new activity staining method, dried agarose film-overlay (DAFO). Pretreatment of semen samples with neuraminidase markedly enhanced the isozyme-band resolution and sensitivity. The method was simple and reliable, with high resolution and sensitivity. The DNase I types in semen samples were correlated with the types found in corresponding blood and urine samples. DNase I typing could therefore provide an additional discriminant characteristic in the forensic examination of semen.     

Drinking and driving in Singapore, 1987 to 1989.

Between 1987 and 1989 there were approximately 5,000 cases of fatal and injury-sustained road traffic accidents, of which 2.3-3.0% were alcohol related (blood alcohol levels greater than the legal limit of 80 mg% ethanol). The offenders of alcohol-related accidents are mostly Chinese (> 79%), male (> 98%), and more often 30-40 years old. The majority of the alcohol-related accidents (> 74%) took place between 8 P.M. and 4 A.M. in fine weather and light traffic. Rear-end, head-on, and side-on collisions comprised > 60% of all the alcohol-related accidents, and losing control of vehicles approximately 30%. Drunken driving cases for the same period that were not accidents showed a number of characteristics similar to those for accidents. In Singapore, motorcycle riders and pedestrians are more prone to road fatality than other road-user groups. International comparisons of road fatalities per 100,000 population gave Singapore one of the lowest accident rates (8.1-8.4) as compared with countries such as Australia, the United Kingdom, the United States, New Zealand, Canada, and Japan.     

Homicides in Auckland, New Zealand. A 14-year study.

In the 14-year period from 1976 to 1989, there have been 174 homicide victims in the Auckland colonial area. Data accessed from autopsy and police reports show that victims of marital conflict, family dispute, and arguments developing between nonmarried couples made up the largest proportion of homicide cases. Stabbing and assault with a blunt weapon were the most common causes of death. The data also show that homicide is relatively uncommon in Auckland in comparison with other cities of similar size.     

Analysis of preliminary procedures in suits against physicians at the Aachen Public Prosecutor's Office between 1978 and 1981

Altogether, 318 preliminary proceedings were initiated against physicians, compared to 2 against nonmedical practitioners. The majority i.e., 192 proceedings, dealt with charges of torture and deprivation of freedom committed against patients under psychiatric treatment. Ninety-nine proceedings were based on negligent bodily injury and negligent homicide and 15 on failure to give medical assistance. Other reasons were given in isolated cases only. The proceedings were mostly initiated against surgeons, psychiatrists, general practitioners, internists, gynecologists, and 2 against nonmedical practitioners (42 because of negligent bodily injury and 48 because of negligent homicide). The charges were dropped in accordance with Section 170,2 StPO in 78 cses, Section 153, 153a and 154 StPO in 7 cases, and there were 7 acquittals and 2 sentences after trial. In the remaining preliminary proceedings, the charges were dropped in 215 cases according to Section 170,2 StPO, and in 2 cases according to Section 153a StPO. Three defendants were sentenced to punishment and 1 received a verdict of not guilty. Thus in most of the preliminary proceedings the charges were dropped.     

Transborder data flow issues and technology transfer

Transborder data flow and technology transfer issues have a substantial overlap. Transborder data flows represent flows of information with economic and/or cultural value. Electronic access to “know-how”, information, data, etc. is becoming more and more important to technology transfer and sharing. National transborder data flow policies either affect or can themselves be technology transfer policies.
