In this article, we discuss under what conditions an estimated cost per statistical life saved can be interpreted as an implied lifevalue. Furthermore, we state optimality conditions with respect to variation in implied lifevalues. The cost-effectiveness, together with references, are presented for 165 lifesaving interventions in Sweden. The cost-effectiveness of interventions has been found in publicly available analyses, or in some cases been calculated by us. Several of these interventions produce net savings for society. The most expensive interventions cost several hundred million SEK, or more, per life saved. To improve the comparability of the interventions, certain criteria have been used to standardize the estimates. Still, dissimilarities in the calculation of implied life values remain and the quality of the original data is in some cases uncertain. Despite this and the fact that the interventions are not a representative sample, it is nevertheless possible to conclude that implied life values vary greatly both within and between different sectors of the Swedish society, much in the same manner as in current U.S. analyses.  相似文献

Subjective fatigue and reaction time performance were measured in a group of 24 aeroplane mechanics, during 1 week of high noise exposure and 1 week of low noise exposure. Subjective ratings were collected before and after each work day. On the last day of each week subjects also completed a reaction time task before and after work. The mechanics felt more sleepy and less energetic during the high noise week. This effect was most evident towards the end of the day and there was a build-up of the effect during the week. Reaction times were prolonged during the high noise week. Possible confounding factors are discussed and found to be less likely explanations of the effects.  相似文献

This is a study of risk perception in relation to New Age (NA) beliefs, including traditional folk superstition and belief in paranormal phenomena, as well as use of alternative healing practices. Data were also obtained on trust dimensions and on personality and psychopathology variables, as well as religious involvement. It was found that four factors accounted for the investigated NA beliefs, which were termed higher consciousness beliefs, denial of analytic knowledge, traditional superstition, and belief in the physical reality of the soul. NA beliefs were strongly and positively related to religious involvement, and negatively to educational level. These beliefs were also positively related to maladjustment and to concerns over tampering with nature. In regression analyses, it was found that NA beliefs explained about 15% of the variance of perceived risk, and that the most powerful explanatory factors were higher consciousness beliefs and beliefs in paranormal phenomena. Traditional superstition and use of healing practices did not contribute to explaining perceived risk.  相似文献

This paper analyses the characteristics of good strategic performance that contribute to the overall performance of a successful company. We apply a framework of pragmatic constructivism in order to analyse and measure strategic performance. We use the model for performance measurement based on pragmatic constructivism for the more specific topics of measuring, assessing and analysing strategic performance as opposed to operational performance. This paper analyses the characteristics of strategic performance that successfully enhance the overall performance of the company. The purpose is to outline a framework for strategic performance measurement that can be used to guide and measure strategic leadership. The framework focuses on the concepts of coherence and coherence tracing as the basic concepts for strategic performance and thus the task for strategic performance measurement.  相似文献

Factors in Risk Perception   总被引:12,自引:0,他引:12  
Risk perception is a phenomenon in search of an explanation. Several approaches are discussed in this paper. Technical risk estimates are sometimes a potent factor in accounting for perceived risk, but in many important applications it is not. Heuristics and biases, mainly availability, account for only a minor portion of risk perception, and media contents have not been clearly implicated in risk perception. The psychometric model is probably the leading contender in the field, but its explanatory value is only around 20% of the variance of raw data. Adding a factor of "unnatural risk" considerably improves the psychometric model. Cultural Theory, on the other hand, has not been able to explain more than 5–10% of the variance of perceived risk, and other value scales have similarly failed. A model is proposed in which attitude, risk sensitivity, and specific fear are used as explanatory variables; this model seems to explain well over 30–40% of the variance and is thus more promising than previous approaches. The model offers a different type of psychological explanation of risk perception, and it has many implications, e.g., a different approach to the relationship between attitude and perceived risk, as compared with the usual cognitive analysis of attitude.  相似文献

Risk Perception by Offshore Oil Personnel During Bad Weather Conditions   总被引:1,自引:0,他引:1  
This article presents the results of analyses of employee subjective risk assessments caused by platform movements on an offshore oil installation in the Norwegian sector of the North Sea. The results are based on a self-completion questionnaire survey conducted among 179 respondents covering three shifts on the platform. The data collection was carried out during the spring of 1994. A minority expressed worry due to platform movements. A greater proportion of the personnel stated worry about the construction of the platform. The personnel were more unsafe when they assessed their own safety attitudes with regard to specific potentially hazardous consequences of platform movements. Two approaches aimed at modeling worry and concern caused by platform movements were tested. The models were the mental imagery approach and the rationalistic approach. The rationalistic and mental imagery models fitted equally well. Implications of the results for risk communication are discussed.  相似文献

Children and youth who have shown serious difficulties or if it is surmised that parents over time will not be able to care for the child or youth, could be placed in a child protection institution. The therapeutic work in such institutions is often described as milieu therapy. There has been little focus on the milieu therapist's relational work in child protection institutions. The research question for this study was: What factors are described by milieu therapists as significant for relational work with youth placed in institutions? To answer this question, we collected data from qualitative semi‐structured interviews with four milieu therapists working in child protection institutions. Interpretative phenomenological analysis helped us identify three overarching categories: (1) structural and personal factors as a basis for relational work; (2) various forms of communication in relational work; and (3) relational work with a starting point in everyday events.  相似文献

While research on Asian American students has overwhelmingly emphasized family ties as an important contributor to student success in high school, what it neglects is how family ties can constrain students in their educational endeavors. Based on a study of 30 low-income Hmong American high school students, I argue that poverty can create conditions in which family ties bind students to gender-based expectations and obligations that prevent them from pursuing opportunities for social mobility. In their discussion of mobility obstacles, Hmong students consistently brought up family as a significant barrier. Whereas males were concerned about fulfilling family obligations related to performing cultural and religious rituals, females were distressed about providing social and economic support for their families. Both males and females framed family obligations as obstacles that interfere with their schooling but females were also concerned that family obligations would restrict their ability to pursue opportunities away from home.  相似文献

The aim of the study was to examine submaximal and maximal physiological responses and perceived exertion during deep-water running with a vest compared with the responses during treadmill running in healthy elderly women. Eleven healthy women 70 +/- 2 years old participated. On two different occasions they performed a graded maximal exercise test on a treadmill on land and a graded maximal exercise test in water wearing a vest. At maximal work the oxygen uptake was 29% lower (p < .05), the heart rate was 8% lower (p < .05), and the ventilation was 16% lower (p < .05) during deep-water running than during treadmill running. During submaximal absolute work the heart rate was higher during deep-water running than during treadmill running for the elderly women. The participants had lower maximal oxygen uptake, heart rate, ventilation, respiratory-exchange ratio, and rate of perceived exertion during maximal deep-water running with a vest than during maximal treadmill running. These responses were, however, higher during submaximal deep-water running than during treadmill running.  相似文献
