Thomas H. Champney 《Anatomical sciences education》2019,12(4):432-434
The value that willed body donors provide to medical education is priceless. Their precious gift helps to teach anatomy, spatial relationships between morphological structures, anatomical variation, and professionalism to medical students in a way that plastic models, podcasts, and lectures cannot. They are also an important resource for medical research and a wide variety of postgraduate training opportunities. While many body donation programs throughout the world are nonprofit organizations, there are body donation companies in the United States that sell donors for-profit. These “body brokers” have accumulated large profits from this business. It is incongruous that others would profit from such a priceless, freely donated gift. To prevent this incongruity, it is proposed that the international anatomical community develop a normative culture (a bioethos) for body donation programs. This would involve the conscious and systematic development of ethical principles for the day-to-day policies and practices of institutions that collect and use human bodies. With the development of this bioethos, a cultural shift in how donors are treated would occur and, over time, this would become the normal practice. These principles would become fundamental and foundational for the procurement and use of priceless human tissues. 相似文献

Thomas L. Bonn 《Publishing Research Quarterly》1994,10(1):55-65
The role of the literary agent and the reception granted agents by publishers have changed markedly over the course of the
twentieth century. Henry Holt’s views of agents, written in the first decade of the century, help define the status and activities
of agents at that time. These are compared with the role of agents today, using archival sources, the book trade literature,
and interviews.
Thomas L. Bonn, review editor of this journal, is a librarian, Library at State University College at Cortland. He is the
author ofUnder Cover: An Illustrated History of American Mass Market Paperbacks andHeavy Traffic and High Culture: The New American Library as Literary Gatekeeper. He is working on a study of American literary agents. 相似文献
