Using judgments obtained in interviews with 33 Massachusetts physicians, the annual statewide volume of expenditures incurred for defensive medical reasons in 1982 was estimated to be $1.0 billion, 12% of all medical care expenditures. Estimates for the nation were $37 billion, 14% of expenditures. Nationally, 180,000 cesarean deliveries were thought to be performed for defensive motives. In their own institutions, respondents judged 43% of all skull x-rays following injury to be medically justified, 30% to be defensive medicine, 16% to be placebos, and 11% to be physician misjudgments. In considering the economic and noneconomic costs of medical malpractice procedures, the dollar costs of insurance were considered most serious, followed closely by defensive medicine, unfairness, and poorer relations with patients. Thirty-two percent of the responsibility for the negative aspects of malpractice processes was assigned to lawyers, 21% to physicians, 18% to legislatures and courts, 16% to patients, and 13% to insurance companies.  相似文献

This paper analyzes similarities and dissimilarities in French and American efforts to come to grip with irregular migration. The symbolic importance of immigration reform is argued to be a key political concern in both nations, although the politics of immigration reform has assumed a more partisan flavor in France, particularly since the municipal elections of 1983. In France, the theme of control and security, associated with the notion of preventing "automatic" immigration which would endanger the cohesion of French society, was widely utilized for political ends prior to and after May 10, 1981 (the date of Francois Mitterand's investiture). The American government, on the other hand, is confronted with the unenviable task of obtaining a legislative consensus on legalization and employer sanctions through an approach seeking to harmonize and integrate the demands articulated by various groups: employers, unions, and alien and ethnic interest groups (principally Hispanic groups divided into a hierarchy along a recently arrived/established cleavage). The American situation most sharply differs from the French case in terms of the absence of a right/left political cleavage. The real effects of clandestine immigration are to be found at the local level. In France, as in the US, the ability of local actors to exert pressure raises the fear that legalization and sanctions will change little, except in terms of symbolic legitimacy.  相似文献

"This article provides some empirical information pertaining to the benefits and costs of foreign labor to Singapore and subjects to critical analysis some of Pang and Lim's hypotheses concerning the costs of labor importation presented in a previous article.... The article concludes with a discussion of the real cost to Malaysia of Singapore's labor importation policies and its potential for disruption of Malaysia's development plans."  相似文献

From time to time during social encounters, people look at one another in the region of the eyes, and sometimes their eyes meet to make eye-contact. According to Argyle and Dean (1965), eye-contact in dyadic encounters signals the intimacy of the interaction and is controlled largely by the competing approach and avoidance forces that motivate the pair. In the present paper, new analyses are reported of three published experiments that were designed originally to test aspects of the intimacy model and it is shown that the duration of eye-contact is no more than a chance product of how long the two subjects look individually. Looking and not eye-contact, it is argued, should be the basis for models of visual interaction, and the intimacy model is ill-founded conceptually; the role of emotion in gaze has been overstressed at the expense of the concept of information; and the most important aspect of vision is in any case not looking and eye-contact but visual access to the whole person. The more cueless the encounter—that is, the fewer the social cues from vision and all the other senses combined—the greater the psychological distance; and the greater the psychological distance, the more task-oriented and depersonalized the content of what people say and, in turn, the less spontaneous their style of speech and the less likely a debate to end in compromise.Research for this article was sponsored by the Social Science Research Council of Great Britain.  相似文献

The biotechnical "revolution" has fast come upon us. It promises to produce both substantial benefits and difficult dilemmas for individuals and society. Despite the growing attention being paid to biotechnology, a major unanswered question is who shall control the development and use of the powerful array of human genetic and reproductive innovations. Should the decisions be left to individual consumers and private industry or should they be made by the government or other social institutions? After briefly reviewing development in human genetics and reproduction and describing trends toward commercialization of them, this article discusses the dilemmas these trends raise for a democratic society. It argues for the urgent need to delineate societal goals and priorities for the future and for technology assessment as early as possible in the developmental process. The article concludes by presenting some examples of the social policy problems now emerging.  相似文献
