Many activities of doctors in the acute hospital sector do not improve patient outcome because they are inappropriate. Curtailing interventions that are unnecessary (because the patient is not bad enough) or are unsuccessful (because the condition is too advanced) could both save resources and improve care. Rational rationing depends on knowledge about the expected benefits of various technologies when used in different clinical circumstances.  相似文献

A SIMPLE interactive programming language is shown to be useful for psychological research involving auditory stimuli and responses. It is helpful in recording spoken stimulus tapes with program control of event sequencing and timing; it can control on-line interactive auditory and bisensory experiments; and it can calibrate the stimulus durations and pause times for auditory events.  相似文献

The authors explored attitudes of young women in the United Kingdom (n = 108) and the United States (n = 91) toward (a) the possession and use of guns through the Attitude to Guns Scale (N. R. Branscombe, J. A. Weir, & P. Crosby, 1992) and (b) guns' perceived functional and symbolic significance through the Symbolic Nature of Guns Scale (C. A. Cooke & J. E. Puddifoot, 1997). There were significant differences in beliefs concerning the right to own a gun and the protective effect of guns but not in the perceived contribution of guns to crime. Although neither group strongly equated guns symbolically with power or control, the U.S. women were more likely to perceive guns as expressions of freedom or independence, and the U.K. women were more likely to view guns as expressions of danger and violence. The findings were contextualized by comparison with samples of male control participants of similar ages.  相似文献

Abstract

The authors explored attitudes of young women in the United Kingdom (n = 108) and the United States (n = 91) toward (a) the possession and use of guns through the Attitude to Guns Scale (N. R. Branscombe, J. A. Weir, & P. Crosby, 1992) and (b) guns' perceived functional and symbolic significance through the Symbolic Nature of Guns Scale (C. A. Cooke & J. E. Puddifoot, 1997). There were significant differences in beliefs concerning the right to own a gun and the protective effect of guns but not in the perceived contribution of guns to crime. Although neither group strongly equated guns symbolically with power or control, the U.S. women were more likely to perceive guns as expressions of freedom or independence, and the U.K. women were more likely to view guns as expressions of danger and violence. The findings were contextualized by comparison with samples of male control participants of similar ages.  相似文献

Nick Thompson studied many animals over the course of his career, including non-human primates, dogs, crows, human babies, and mockingbirds. Amidst such variation, Nick maintained a common focus. He sought to provide more accurate and truthful representations of the particular phenomenon of interest. His writings on mentalism, design, anthropomorphism and use of metaphor have provided fellow scientists with insight and helped advance his field of study.  相似文献
