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.     

Woman abuse in university and college dating relationships: The contribution of the ideology of familial patriarchy

Several theorists contend that male university/college students who physically, sexually, and psychologically abuse their female dating partners are more likely than men who are not abusive to adhere to the ideology of familial patriarchy. These scholars also argue that men who hold familial patriarchal attitudes and beliefs, and who are supported by their male peers, are most likely to victimize their dating partners. This research provides quantitative data from a national representative sample of Canadian male undergraduate students that support these hypotheses. This study was sponsored by a grant from the family Violence Prevention Division, Health and Welfare Canada The views expressed in this paper are those of the authors and do not necessarily reflect those of Health and Welfare Canada.     

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.     

Causes of death of patients in an institution for the developmentally disabled

The causes of death of 53 severely to profoundly developmentally disabled patients who died in an intermediate care facility were reviewed. Respiratory disease, predominantly pneumonia and aspiration, accounted for 72% of deaths. Seven patients died of nonrespiratory causes, and in 8 patients, no cause of death could be determined, even after a complete autopsy or investigation. The median age at death was 20 years. The weights of these patients' organs at autopsy were lower than those for normal individuals of the same age. The lifespan of these severely impaired individuals continues to be significantly shortened, even with improved methods of care.     

Technology transfer at land-grant universities

Improvement in the ability of universities in the United States to transfer technology to the private sector is seen as a factor in strengthening American competitiveness. To better understand the university's role in this process, a survey of formal university programs in technology transfer was performed through personal interviews at four midwestern land-grant universities. There are six basic types of programs in place: technical assistance, affiliate, licensing, business development, incubators and research parks, and information networks. For purposes of classifying these programs, we used the model developed by Janis et al. (1) It was found that, of the six modes of technology transfer, two could be considered active, three semi-active and one passive.
