The right to die may be among the most legally complex and culturally sensitive areas of civil rights to emerge in our time. The thorny issues associated with a terminally ill individual's right to self-determination, and the disposition of individuals who are incompetent to make right to die decisions for themselves, promises to keep all parties involved - health care professionals, medical ethicists, families, lawyers, judges, and state legislators -busy for some time to come. To this point, the state courts have taken the lead in the right to die debate, while the state legislatures have tended to drag their collective feet. This article lays the case law groundwork for right to die decision making, then goes on to assay the legislative responses to the issue that have been rendered in the fifty states.  相似文献

The Iran-Contra affair is an example of the type of event that is expected to give rise to a rally of public opinion behind the president. However, the public's response to this event, uncharacteristically, was a sharp decrease in support for President Reagan. This case study constitutes an attempt to explore the sources of the public opinion response to foreign policy events. Statements of political elites, news coverage and commentary, and public opinion assessments are examined to test the patriotism, priming, and opinion leadership explanations of the rally phenomenon. The actions of opinion leaders appears to provide the best explanation of the differential public response to the Iran-Contra affair.  相似文献

We report seven fatalities resulting from the ingestion of illicit drugs packaged in condoms, rubber balloons, or plastic bags which were observed in the last 4 years at the Office of the Chief Medical Examiner, State of Maryland. All the victims, with the exception of one, were men ranging in age from 19 to 37 years. There was no racial predominance. No drug paraphernalia was found at any scene. In two cases, seizure-like activity was documented. One victim had recently returned from Nigeria; therefore, Lassa fever was initially suspected. Two of the victims were "body packer" contrabanders who had just arrived from Africa. They used body cavities to hide large amounts of heroin to avoid U.S. Customs. The other five cases were "mini-packers," small-time illicit drug dealers who had swallowed a single bag of cocaine to avoid police detection. The possible mechanism of leaking or rupture of the latex container is discussed.  相似文献

Analysis of a sample of 1108 radii corresponding to 567 black and white North Americans in the Terry Collection at the Smithsonian Institution demonstrates that the diameter of the radial head is an accurate sex discriminator for human remains. A simple "radial-head method" of sex determination consists of measuring the maximum and minimum diameters of the head and comparing such measurements with the test cutoff points. The subject is female when the maximum radial head diameter (either left or right) is less than or equal to 21 mm, and male when the maximum diameter (either left or right) is greater than or equal to 24 mm. The same decisions apply to the minimum diameters of 20 mm or less and 23 mm or more, respectively. When the maximum diameter is 23 mm or the minimum is 22 mm, the subject is more likely male; when the maximum diameter is 22 mm or the minimum is 21 mm, the subject is more likely female. The sample frequency of any one of these latter diameters is never more than 16%. Cross-validation of the method with a sample of 50 pairs of radii of the Terry Collection, different from the original specimens, resulted in 92% sexing accuracy when using the left radius singly, 94% accuracy when using the right radius singly, and 96% accuracy when using both radii jointly.  相似文献

During preliminary examination of the body of a homicide victim, a peculiar red "fiber" was noticed and recovered. Initially believing this to be a carpet fiber, the item was subjected to fiber analysis. It was found to be a short coiled particle not like any known natural or synthetic fabric fiber. Subsequent examinations determined this "fiber" to be the larva of a common freshwater midge (Diptera; Chironomidae). Chironomid larvae have been observed on other bodies recovered from freshwater environments. Entomological studies of this organism have led to the conclusion that the presence of chironomid larvae indicates submersion of the body.  相似文献

Programme based on mathematical model of the process of dead body temperature changing was developed for estimation of postmortem interval. Automatic retrieval of problem solution was performed on programmable microcalculators of "Electronica MK-61" type using adaptive approach. Diagnostical accuracy in case of dead body being preserved in permanent cooling conditions is +/- 3%.  相似文献

<正> 在1987年8月24日的《北京周报》上,我第一次谈到的有关中国立法文选的一个短评。几个月后,在中国首都,我起初拟买两卷中国法律汇编。遗憾的是,在我所光顾的书店里,所有能买到的只有英译的刑法和刑事诉讼法,以及若干有关国家外资经济之立法的译本。据悉,我所要买的那两个版本,很快便销售一空。只是到了后来,通过一位在人大常委会秘书处工作的好心年青人,我才终于搞到那套书。这个两卷本的法律汇编共有约800页,外国人对之有兴趣是可以理解的。它提供了120多个当今中国有效的法规英译名。这个版本是"法制委员会  相似文献
