It has been suggested that the advance of science and technology in the West has changed both the relationship of man to nature and of man to man. With regard to human reproduction, science and technology in medicine may certainly change the relationship of man to nature and of man to man, but also the concept of what it means to be human. Efforts must be taken to guarantee the rights of all humans. The author explores developing reproductive medical technology to consider how it may change our concept of humanness and how that change may be accommodated, encouraged, or impeded by the relationship between the government and its pregnant citizens as defined by the US Constitution and the right to privacy. Sections discuss the Constitution at the beginning of life; sterilization and the right to procreate; contraception, abortion, and the right not to procreate; and surrogacy. The author also discusses constitutional issues when the interests of a pregnant woman conflict with those of the fetus in terms of fetal surgery, forced cesarean-section cases, and the fetal abuse case of Pamela Monson Stewart.  相似文献

Recently, an unusual case of autoerotic death in which a man died of hypoxia after having enclosed himself in plastic was reported in this Journal (1). We present a second case showing many similarities to the one published previously.  相似文献

This paper analyzes the role of coordination criteria in employment and training service delivery within the Job Training Partnership Act system. The evolution of coordination criteria is related to current initiatives in the Employment Service at the state and local levels. An operational set of program outcome measures for monitoring coordination efforts is discussed. This set of outcome measures is formulated in the broad context of stabilizing employment and averting the "structuralization" of unemployment impacts wrought by fundamental economic change in the labor market. The assessment and monitoring of such coordination efforts is discussed.  相似文献

A series of experiments were conducted using various types of pollen grain, powder and metal particulates to determine their persistence on a range of different types of materials. The decay curves generated in the repeated experiments all broadly conform to those obtained and already presented in the literature for fibres and glass particulates. The experiments presented in this paper were conducted for up to 647 hours for individual runs and it was found that a general rule existed that it was the material type rather than the particulate type that was the major controlling factor in the persistence of particles. For the pollen grain experiments the overall theory is sustained; there is a significant loss initially followed by a slower decay although this is not precise given the varied nature of palynomorph types. The manner by which the particulates were introduced onto the material had an initial immediate effect, however, the persistence of these particulates over longer periods of time was generally unaffected.  相似文献
