Ninety-nine bicycle and motorcycle accidents were analyzed that had taken place from 1980 to 1984 in and around Frankfurt on the Main. The postmortem examinations were done in the Center of Forensic Medicine at the University of Frankfurt. Twenty-five percent of the bicycle riders were children up to the age of 15 years and 25% were elderly people over the age of 60. Most of the people involved in motorcycle accidents were between 17 and 24 years of age. The greatest amount of accidents took place in the summer, but in October there was also a peak. On weekdays, Thursday was the day when most of the accidents happened and Sunday showed the least. About 50% of the bicycle accidents happened in the city; 44% of the motorcyclists had lethal accidents on normal roads in the country. The most dangerous situation for bicycle riders was created by fast vehicles following them, but intersections proved to be a danger point, too. Nearly 40% of the motorcycle accidents were not caused by other vehicles. The most frequent cause of death was head injuries (45%), followed by injuries of the internal organs and spine. Many bicycle riders caused the accidents themselves (43.6%). Most of the fatal motorcycle accidents were caused by others (56%). In all of the cases studied, 30% of the participants involved had a relevant blood-alcohol concentration. 相似文献

Gotha Canal is perhaps the most gigantic construction work ever undertaken in Sweden. It is a seaway through Sweden that connects the Baltic Sea with the Atlantic Ocean. It is nowadays considered to be one of the most famous cultural landmarks in Sweden from the time it opened for traffic the canal was in 1832 until 1978 the canal was privately owned. Since then, it has been owned by the state. Such a long time of private ownership of transportation link is remarkable. This paper analyses why the change from private to state ownership finally took place and also looks at the implication of this ownership change for profit maximising behaviour and maintenance of the canal. A discussion of how ownership of a cultural landmark like Gotha Canal can be structured is also provided. 相似文献

It is well known that psychopaths are a group with high risk for criminality. Despite that, researchers and clinicians have not yet agreed on a general cause of psychopathy. However Raine [Raine, A. (2002). Biosocial studies of antisocial and violent behavior in children and adults: A review. Journal of Abnormal Child Psychology, 30, 311-326.] advocated a biosocial model of violent behaviour where the greatest risk for criminal behaviour occurred when both heredity and environmental risk factors (e.g., social class, childhood history) were present. In this follow-up study, 35 men convicted of homicide were assessed retrospectively for psychopathy according to the Psychopathy Checklist-Revised (PCL-R). Information on personal history, as well as from legal documents and records of offences committed by the subjects was also obtained. Fourteen of the 35 men were classified as psychopaths. Two men, both rated as psychopaths, had criminal parents. Twenty-seven of the men had a social relationship with their victim, and eleven out of these were rated as psychopaths. There was no difference in PCL-R scores between those who had a social relationship with their victim and those who did not. The psychopaths relapsed more frequently than the nonpsychopaths into criminality after their prison term. This result confirms previous research indicating that psychopathy is a risk factor for recidivism. It is, therefore, very important that psychopaths get the best possible treatment, aftercare, and supervision. 相似文献
