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

The National Abortion Rights Action League (NARAL) and the Women's Legal Defense Fund (WLDF) co-authored an "amicus curiae" brief in "Webster." The brief was written for 77 organizations who believe in equality of women. The brief said that constitutional protection of a woman's right to choose is guaranteed by the right to privacy. The brief said that if abortions were illegal, women would not be able to take place in society equally with men. Liberty would be taken away from women. If the state interferes with abortion, the principle of bodily integrity is violated. In "Winston v. Lee," the Supreme Court found that the state could not compel a criminal to undergo an invasive surgical procedure to retrieve a bullet necessary for the state to prosecute with. 1 in 4 women have a cesarean section, which requires a larger incision in the abdomen, and has many risks. Bearing and raising children often puts a damper on women's employment opportunities. Therefore, if the Supreme Court denied women the right to bear children when and where they wanted, women would not have the right to plan their futures. If the Supreme Court were to agree that "interest in potential life outweighs" a woman's tight to procreate autonomously, states could declare all abortions illegal, investigate them to see if they were induced on purpose, and murder women who induced them. Contraceptive devices could be declared illegal. Laws could be used to force women to submit to cesarean sections and other fetal surgery. Pre-viability abortion restrictions should be rejected because they have old-fashioned notions of women's role in society. They reinforce stereotypes. Missouri's law stresses aiding "potential," rather than actual life. 相似文献

The authors present a historical overview of urbanization in Venezuela. The impact of the oil economy on population change and spatial distribution is emphasized. A typology of cities based on socioeconomic function and on a demographic classification of urban centers is devised. Future trends in urbanization are also considered. (SUMMARY IN ENG) 相似文献

The paper by Gaudette and Keeping on "An Attempt at Determining Probabilities in Human Scalp Hair Comparison" in the Journal of Forensic Sciences (Vol. 19, No. 3, July 1974, pp. 599-606) has provoked considerable controversy. This paper highlights two of the sources of the controversy and shows how the probability, 1/4500, quoted by Gaudette and Keeping should be treated with caution. The necessity of the use of a likelihood ratio statistic is described. It is suggested that the hair examination form resulting from the responses to the questionnaire recently distributed by the authors and also the discussions at Quantico (Proceedings of the International Symposium on Forensic Hair Comparisons, 25-27 June 1985, Quantico VA) should be used to facilitate the collection of the data which will be necessary to enable a likelihood ratio statistic to be estimated effectively. 相似文献
