Hyperextension of the head can cause injury to the vessels at the base of the brain. These lacerations are believed to be caused by stretching of the vessels due to the abrupt movement of the head and rotational acceleration of the brain within the cranium, and they usually occur in the intracranial portions of the vessels, producing a subarachnoid hemorrhage. This is the case of a 35-year-old man who received a blow to the face that forcefully hyperextended and rotated his head to the left. Autopsy revealed an intracranial right internal carotid laceration extending from a calcified atherosclerotic plaque. This unusual injury may be due to a combination of blunt force applied to the head and the alteration of the vessel's structural and functional capacities secondary to atherosclerosis. 相似文献

In relations with their state-owned enterprises, governments try to capture the advantages that are thought to exist in operating through autonomous institutions. At the same time, they attempt to prod the enterprises toward a set of governmental goals. The resulting relationships between ministers and managers have produced a pattern of behavior by state-owned enterprises that differs considerably at times from those of private enterprises. But articulating the goals of the government in ways that are internally consistent has proved difficult, as has securing the benefits of autonomy. Some governments are attempting to improve the relationship with their state-owned enterprises by developing explicit agreements, even contracts, between ministers and managers. Although this approach does not face up to some basic problems in the manager-minister relationship, it cannot be ruled out as a significant step in improving the link. 相似文献

The role of biological maturity in behaviors in adolescence which most often are considered as negative by adults was investigated for a normal group of girls. In mid-adolescence early matured girls were found to play truant, smoke hashish, get drunk, pilfer, ignore parents' prohibitions, considerably more often than did late maturing girls. These differences between biological age groups were mediated by the association with older peer groups and they leveled out in late adolescence. Data on alcohol consumption and crime at adult age showed little association with biological maturation. A hypothesis was tested suggesting that early biological maturation may have negative long-term consequences within the education domain. In accord with this assumption, a considerably smaller percentage of girls among the early maturers had a theoretical education above the obligatory nine-year compulsory schooling than among the late maturing girls. The association between biological maturation and adult education was significant also after controlling for standard predictors of education, such as the girls' intelligence and the social status of the home. The requirement of conducting longitudinal studies when investigating issues connected with maturation was strongly emphasized.The research presented here was supported by funds to D.
