The Physicians' End-of-Life Care Attitude Scale (PEAS) was developed as an outcome measure for palliative care education. PEAS assesses the willingness of medical trainees to care for dying patients. Sixty-four Likert-type questions were created on the basis of discussions with focus groups of medical trainees, then administered to sixty-two medical students and residents. Total PEAS scores as well as personal preparation and professional role subscales (where higher scores indicated greater concern) possessed excellent internal consistency and reliability. In addition, there were substantial correlations between PEAS scores and the CA-Dying scale, a measurement of laypersons' fears about interacting with dying persons. Thus, PEAS adequately assesses the unique communication concerns of physicians in training regarding working with dying persons and their families. Correlations between PEAS scores and age were negative, while those who had experienced the death of a loved one had higher PEAS scores than those who did not. This suggests that for some persons, life experiences may lessen difficulties in dealing with dying persons, while for others, personal losses may exacerbate such concerns. The utility of PEAS in evaluating the efficacy of palliative care education as well as its potential to measure medical trainee's willingness to care for the terminally ill is discussed. 相似文献

Health Risk Assessment of a Modern Municipal Waste Incinerator 总被引:2,自引:0,他引:2

During the modernization of the municipal waste incinerator (MWI, maximum capacity of 180,000 tons per year) of Metropolitan Grenoble (405,000 inhabitants), in France, a risk assessment was conducted, based on four tracer pollutants: two volatile organic compounds (benzene and 1, 1, 1 trichloroethane) and two heavy metals (nickel and cadmium, measured in particles). A Gaussian plume dispersion model, applied to maximum emissions measured at the MWI stacks, was used to estimate the distribution of these pollutants in the atmosphere throughout the metropolitan area. A random sample telephone survey (570 subjects) gathered data on time-activity patterns, according to demographic characteristics of the population. Life-long exposure was assessed as a time-weighted average of ambient air concentrations. Inhalation alone was considered because, in the Grenoble urban setting, other routes of exposure are not likely. A Monte Carlo simulation was used to describe probability distributions of exposures and risks. The median of the life-long personal exposures distribution to MWI benzene was 3.2·10–5 g/m3 (20th and 80th percentiles = 1.5·10–5 and 6.5·10–5 g/m3), yielding a 2.6·10–10 carcinogenic risk (1.2·10–10–5.4·10–10). For nickel, the corresponding life-time exposure and cancer risk were 1.8·10–4 g/m3 (0.9.10–4 – 3.6·10–4 g/m3) and 8.6·10–8 (4.3·10–8–17.3·10–8); for cadmium they were respectively 8.3·10–6 g/m3 (4.0·10–6–17.6·10–6) and 1.5·10–8 (7.2·10–9–3.1·10–8). Inhalation exposure to cadmium emitted by the MWI represented less than 1% of the WHO Air Quality Guideline (5 ng/m3), while there was a margin of exposure of more than 109 between the NOAEL (150 ppm) and exposure estimates to trichloroethane. Neither dioxins nor mercury, a volatile metal, were measured. This could lessen the attributable life-long risks estimated. The minute (VOCs and cadmium) to moderate (nickel) exposure and risk estimates are in accord with other studies on modern MWIs meeting recent emission regulations, however. 相似文献

Sometimes conducting an experiment to ascertain the state of a system changes the state of the system being measured. Kahneman & Tversky modelled this effect with support theory. Quantum physics models this effect with probability amplitude mechanics. As this paper shows, probability amplitude mechanics is similar to support theory. Additionally, Viscusi's proposed generalized expected utility model has an analogy in quantum mechanics. 相似文献

The authors use longitudinal data from the National Longitudinal Survey of Youth to investigate whether the wage trajectories of male high school dropouts are affected by the acquisition of the General Educational Development (GED) credential, by postsecondary education, and by training. The authors show that acquisition of the GED results in wage increases for dropouts who left school with weak skills, but not for dropouts who left high school with stronger skills. College and training provided by employers are associated with higher wages for male dropouts. 相似文献

Although male sexual abuse has co-existed with female sexual abuse, the professional literature has paid minimal attention to the impact of sexual abuse of male children to their adult adaptation. This paper concentrates on the negative impact of sexual abuse on the adult male's gender identity. Examples of eight male clients' responses to sexual abuse in their adult life and the therapeutic framework utilized to work with them are discussed in the paper.This paper was originally presented at the ICAPP conference, 1993.He teaches advanced clinical practice, Human Behavior and AIDS ELECTIVE. He maintains a private practice specializing in Gay men, persons with HIV virus. 相似文献

Disability issues are achieving increasing prominence in Great Britain and the rest of Europe. However, many of the main arguments, particularly those emphasizing social barriers models of disability, are located within structuralist frameworks. This can be regarded as problematic, as poststructural and postmodern orientations challenge the basic tenets of such formulations. This article explores the making of links between modern and structural and postmodern and poststructural perspectives using a gendered analysis drawn from feminism. It then examines the applicability of the resultant analysis for disability issues, social work and research. In conclusion, it is suggested that the making of such links can enable us to accept and effectively utilize difference and diversity, contradiction, change and fluidity without losing sight of enduring social divisions and associated oppressive responses. 相似文献

This article discusses the reciprocal relationship between public pension policy and age-based politics in Brazil, a nation with a public pension system that has the potential for influencing policy developments in other developing nations faced with the problem of how to extend social security coverage to the entire population. Our goal is to extend a line of analysis used in previous studies of industrial nations to the case of Brazil. Pension policy changes made during the 1960s and 1970s had a number of unintended consequences. One was the role these policy changes played with respect to the emergence of rural unions and age-based interest groups: both are becoming increasingly important actors with respect to pension policy. We discuss the implications of the Brazilian case for policy options and outcomes in other newly democratic nations, particularly those in Latin America. 相似文献
