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. The author is grateful for resources provided through the Social Sciences and Humanities Research Council of Canada, the Department of Anthropology and Sociology (University of British Columbia), and the School of Criminology, Simon Fraser University. Comments from Carol Bullock, Nanette Davis, Bob Ratner, Livy Visano and the Journal referees have been helpful in revising this paper.  相似文献

In 90 forensic autopsies (Craniocerebral injury, gunshot, stabbing, blow, strangulation, etc.), semithin sections of great arteries were prepared from around 770 Epon blocks and checked for vital reactions at the mural and intimal ruptures. In 21 cases in which death had occurred immediately or soon after the trauma, with three exceptions, there was a subsequent electron microscopic investigation. In all six mural ruptures and in five of ten intimal ruptures, thrombocyte aggregates were found at the rupture margins. In five intimal ruptures, the possibility of the occurrence of preparations injuries had to be considered. In five cases, the results of the histological study were negative. The success rate is limited in principle in such a screening test since there are technical difficulties in preparing serial sections on long vessels. Death was rapid and the thrombocytes were observed to adhere to the injured wall sites immediately after the trauma. The "thrombocyte sign" is thus of substantial importance as the earliest local vital reaction. In two control cases (strangulation), thrombocyte aggregates were found at intimal ruptures of the basilar artery, which were regarded as the results of stretching via the vertebral arteries during attacks to the neck. The healing processes of intimal ruptures and traumatic medial necrosis in incomplete ruptures occurring later in life are discussed. Even if a cadaver is a few days old, the histological findings at the level of the thrombocytes can be evaluated.  相似文献

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

Atypical entrance gunshot wounds may be produced by deflected or ricocheting bullets. One special type of atypical entrance wound involves abrasion of the skin at a site that is remote from the point of dermal penetration. These remote abrasions, termed "tumbling abrasions," are produced by bullets that tumble after impact with an intermediate target. Three cases of tumbling abrasions are presented.  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
