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

The New Midwifery, a form of community midwifery rooted in home birth and intensive prenatal and postnatal care, has attracted great controversy since its appearance in British Columbia in the early 1970s. On the one hand, this form of community midwifery has endured despite legal prohibition. Midwives derive an income from their practices, obtain necessary supplies and equipment, and are active in lobbying for recognition through the State. On the other hand, community midwifery is marginalized and illegal. Out-of-hospital births comprise less than one percent of births in British Columbia (and nationwide). Community midwives are excluded from the provincal Medical Services Plan and they lack hospital privileges if their clients are transferred to hospital. Community midwives are more likely than medical personnel to be tried for criminal negligence causing death and subject to prosecution under theMedical Practitioners Act of practicing medicine without a license.Community midwifery illustrates the structural limits placed on female birth attendants working outside the norm of professionally accredited, hospital situated childbirth. It is concluded that State measures in Canada structure power relations in a dialectical fashion. This includes measures to consolidate the monopoly status of the medical profession and the nursing profession, while temporizing about demands for independent midwifery practice. State powers are however relatively autonomous of dominant economic groups such as the Medical profession. Not all prosecutions of community midwives are successful, and contradictions in State policies surrounding monopolistic powers and civil liberties, and gender relations are evident.An earlier version of this paper was presented at the Canadian Sociology and Anthropology Association Meetings, University of Manitoba, June 1986.

Shime-waza or the "choke hold", when properly applied, should not cause death; therefore, its primary purpose should be to subdue violent suspects. When properly applied, the choke hold causes unconsciousness in 10 to 20 s. No fatalities as a result of shime-waza have been reported in the sport of judo since its inception in 1882. Among the methods of "control holds" taught to law enforcement officers is the choke hold similar or identical to shime-waza used in judo. Using the choke hold, officers may afford themselves maximum safety while subjecting the suspect to a minimum possibility of injury. The author has reviewed 14 fatalities with autopsy findings where death was allegedly caused by the use of choke holds.  相似文献

A 19-year-old school boy suffered from fluctuating uncharacteristic chest pain in the last 20 h before his death. He died unexpectedly within a few minutes of a hemopericardium, which resulted from an aneurysmal rupture of the ascending aorta. The patient's past history as well as the autopsy and ultrastructural findings led to the diagnosis of Marfan's syndrome with alterations of the cardiovascular skeletal system but no ophthalmological involvement ("oligosymptomatic" form of Marfan's syndrome). Appraisal of the cause of death is made more difficult by the fact that medical treatment was undertaken on the same day, whereby subtotal liver crushing was established that had resulted from attempts at resuscitation.  相似文献

Transfer trauma is alleged to be an increase in morbidity and mortality in institutionally relocated chronically ill elderly. Efforts by the legal profession to persuade courts that transfer trauma should be a legally recognized phenomenon invoking judicial protections against transfer (the "transfer trauma argument") have been unproductive. In O'Bannon v. Town Court Nursing Center, Inc., the United States Supreme Court denied standing to elderly persons claiming a property interest in remaining in alleged substandard facilities. The Court rejected the argument that the possibility of transfer trauma constituted a deprivation of life or liberty that would have required due process protections of notice and hearing. Despite the Court's preclusion of transfer trauma litigation in a constitutional context and the general unwillingness of lower courts to recognize the phenomenon, attorneys continue to burden the judicial system with frivolous transfer trauma arguments. The unfruitful pursuit of a judicial remedy for the ethical and social problems that arise with relocation of the elderly continues, in part, because of a misguided belief that this distressing social phenomenon is best remedied by the courts. Judicial unwillingness to recognize the transfer trauma argument, however, does not preclude legislative consideration of the humanitarian issues concerning the institutional relocation of elderly persons. This Article examines gerontological research in order to understand the judicial rejection of the transfer trauma argument and argues in support of legislative and educational solutions for the ethical and social problems attending transfer.  相似文献
