Larvae of the flesh fly Boettcherisca peregrina (Robineau-Desvoidy) were reared on the tissues of rabbits to study the effects of heroin on the development rates of this species. The rabbits were given 6, 12, 18, and 24 mg of heroin by cardiac puncture. From Hours 18 to 96, larvae feeding on tissues containing heroin (as morphine) developed more rapidly than those feeding on tissues from the control. The time required for pupation was significantly greater for colonies fed on tissues from heroin-dosed rabbits than for the control colony. The differences observed in the rates of development were sufficient to alter postmortem interval estimates based on larval development by up to 29 h and estimates based on pupal development by 18 to 38 h. 相似文献

This essay is about the jazz musician and black variety stage artist Valaida Snow and the years she spent caught in Nazi occcupied Denmark. Despite rumors that she was held in a concentration camp, this essay argues that she may in fact have been shielded from the occupiers by the Danes. This essay argues that a masculinist bias in popular cultural/jazz studies obscures the histories of black women expressive artists and limits theoretical possibilities in the study of performance. It argues that the study of black women performers demands the development of more supple analytical models that attend to the heterogeneity of black expressive forms. 相似文献

The right to refuse treatment is the most controversial of the rights of mental patients, and usually polarizes the movement for mental health reform between providers of care and external activist reformers. A broad alliance supported earlier struggles for recognition of patients' rights, but most professionals oppose recognizing this most extreme right of treatment refusal. Professional opposition to treatment refusal is not based on a wide extent of actual refusal; rather it derives from a defense against challenges to professional and institutional autonomy, an opposition to legal interference, and a belief that the community as well as the patient must be protected. These three reasons for opposition are examined by reviewing studies of attitudes toward patients' rights, knowledge about patients' rights, and implementation of patients' rights. Finally, the implications of these studies for future directions in the movement for patients' rights are examined. 相似文献
