Periventricular leukomalacia (PVL) is a form of cerebral infarction occurring in neonates, particularly in low-weight and premature infants. PVL is well-known to neonatologists, but generally considered nonfatal. Many infants with PVL die in the hospital with multiple medical problems. Those infants with PVL who survive because of intensive care will have serious motor and sensory deficits, but these problems are rarely recognized before one year of age. When infants with PVL die at home, death seems sudden and unexpected. However, it is important to distinguish death caused by PVL from the Sudden Infant Death Syndrome because the implications for the family are quite different. This case report emphasizes that PVL may be fatal.  相似文献

Citizens have always had an important role in the crime control process; they are most often responsible for the detection of crime. It is imperative, therefore, that citizens perceive police officers to be competent and just in the execution of their duties; in the absence of such confidence, the process suffers. Ironically, the groups which are most often the victims of crime hold the most negative attitudes toward the police. Minorities in urban communities, particularly blacks, fit this pattern. These attitudes appear to be linked to the perception of negative, differential experiences with the police, experiences which often lead to the filing of a formal complaint. Using a data set from the complaint files of a large American city, this article explores the relationship between the attitudes of blacks toward the police, experiences with the police, and complaints lodged against the police.  相似文献

This paper draws upon research done at the Centre for Law and Computing at the University of Durham into different types of Computer Assisted Learning ('CAL') programs in law. The research concentrates on linear CAL programs and the features which authors may wish to incorporate into their programs in order to increase their effectiveness. It examines four linear CAL programs which were written with the specific goal of developing an understanding of basic legal principles. The findings of the research highlight the limitations of linear CAL, whilst making several specific suggestions how such programs should be implemented and enhanced.  相似文献

In this paper we examine the actual legal situation concerning the attribution of geostatic positions and frequencies and the problems of frequency interference by other satellites due to not fully clear property rights. We analyze the property rights setting governing satellite communications and review the implications of the Coase theorem of these rules through a game theoretical approach between two players: Russia and Greece (Hellasat commercial communication attempt). The basic finding, in accordance with the theorem's prediction under non-zero and possibly high transaction costs, is that the end result may be sub-optimal due to the inappropriate present specification of property rights, leading either to non-use of scarce resources, or to total over-investment.  相似文献
