Georg Lind is being interviewed by Helen Haste about his work in moral psychology. In the interview, he discusses the meaning and measurement of moral competencies, which he sees as crucial to bridge the gap between moral ideals and action, and to maintain modern democracies, which rely on the enactment of shared moral ideals. Lind has carried out and inspired one of the largest research programs in moral psychology, including longitudinal, cross-cultural, intervention, and experimental studies. His new methodology, the Moral Judgment Test, has been translated and adapted into many languages. Lind has also contributed much to the improvement and dissemination of educational methods to foster moral competencies. The intellectual and biographical roots of his interests are explored.  相似文献

Summary. The cumulative number of human immunodeficiency virus (HIV) infections worldwide has reached 60 million in little over 30 years. HIV continues to spread despite a detailed understanding of the manner in which it spreads and measures which can prevent spread. Some governments have been highly successful in containing the spread of HIV through blood products and from mother to child and among injecting drug users. Lack of political will, lack of resources or challenges to widely accepted scientific evidence have held back similar interventions in other countries. It has proved much more difficult to reduce the sexual transmission of HIV in both high and low income countries. A wide range of strategies has been identified but it remains unclear which strategies deserve priority and what methods of promoting them have the greatest effect. There is ample evidence that awareness of HIV and changes in sexual behaviour have occurred widely but the penetration of information remains poor in some vulnerable groups especially adolescents and women in poorer countries. Further obstacles face those who have information about the risk. The subordinate position of women and a desire for large families are important obstacles to condom negotiation and use. Urbanization, poverty, conflict and declining public services all exacerbate unsafe sexual behaviour. We argue that so-called 'structural' interventions directed at these wider contexts of unsafe behaviour merit greater attention. Such approaches have the added benefit of being less susceptible to 'risk compensation' which has the potential to undermine strategies directed at reducing the transmission efficiency of HIV.  相似文献

Foot and mouth disease (FMD) is considered by many as the most important animal disease in the world. FMD is highly contagious and outbreaks incur significant costs as affected countries are severely limited in their ability to trade. A number of trade commodities may be contaminated with FMD virus (FMDV) including animal products, for example, meat. As a member of the European Union, Great Britain (GB) has put in place a number of regulations to prevent the importation of pathogens in imported meat products. However, the illegal importation of meat provides a route by which safety controls may be circumvented and meat from FMD affected areas may be imported. This study assesses the FMD infection risk posed to the livestock population of GB from the illegal importation of meat, and estimates the major contributors to this overall risk, through the development of a quantitative risk assessment model. From model results, the total amount of illegal meat entering GB each year is estimated on average to be 11,875 tonnes. with 90% certainty that this is between 4,398 and 28,626 tonnes per year; of which between 64.5 and 565 kg are contaminated with FMDV. This flow of illegal meat results in an estimate of a frequency of FMD infection in GB livestock of 0.015 cases of infected animals per year, with 90% certainty it is between 0.0017 and 0.053. Imports from the region Near and Middle East account for 47% of this risk, and 68% of the risk is attributed to bone-in and dried de-boned products.  相似文献

Which countries tend to sign international environmental treaties and why? This study tests the ability of quantitative cross-national political and economic analysis to predict participation in international environmental agreements over the period 1963–1987. Cross-sectional ordinary least squares regressions suggest that poor, highly indebted countries that are dependent on very few trading partners and that have repres-sive regimes are far more likely to be nonsignatories. The results suggest strategies for increasing the likelihood that nations will ratify hture environmental treaties.  相似文献

Working with a treatment and observing team at the same time, behind the oneway mirror, offers a variety of ways to: (a) generate multiple realities; (b) work with two different models of family therapy simultaneously; and (c) provide feedback on the teams' own roles, rules and group process. The process that 6 trainees and two supervisors used with T and O teams to examine their own coevolution as a therapeutic system using the Milan model of family therapy and Ericksonian hypnotherapy is described. The article concludes with a discussion of the advantages and pitfalls of this type of dual supervision.  相似文献

"The purpose of this article is to place Chinese labor migration from agriculture within the context of the literature on labor mobility in developing countries by comparing it to undocumented Mexican migration to the United States. The similarities fall within three general areas: the migration process, the economic and social position of migrants at their destination, and the agrarian structure and process of agricultural development that has perpetuated circular migration. The last section of the article draws upon these similarities, as well as differences between the two countries, to generate predictions concerning the development of labor migration in China."  相似文献

Ten days after the Symbionese Liberation Army's shoot out in Los Angeles in 1974, the Cedars-Sinai Medical Center, Department of Family Child Psychiatry, Thalians Community Mental Health Center, sent a crisis team of three psychotherapists to a school in the black community. The psychotherapists used an art therapy approach with a third grade classroom of 21 black children. The team's procedure helped the children ventilate their reactions to a frightening event which occurred in their neighborhood. This paper describes the art therapy techniques which were utilized, the children's vivid pictorial and verbal expressions accompanied by the psychological aspects of their responses.  相似文献

One indirect (PSQ) and two direct (CSQ-18B and ERS) measures of patient satisfaction were compared across a series of psychometric, acceptability, and concurrent validity criteria. None of the three measures was significantly related to health status or demographic characteristics. Each measure performed as expected from prior research on their psychometric properties. The scales contrasted, however, in regard to acceptability, with the PSQ being much less acceptable to patients than the other two. The PSQ also produced more missing data. The results on the PSQ reflected patient inconsistency on cross-check items and patients tended to be uncertain in their responses to many items. In multivariate analyses the three measures were used as predictors of patient-rated indices of global service satisfaction. The CSQ-18B and the ERS were significant predictors of patient-rated indices of global service satisfaction, whereas the PSQ was unrelated to these indices. It was concluded that the direct and indirect approaches measure different satisfaction domains. The PSQ likely assesses more generalized attitudes about health services while the CSQ-18B and the ERS efficiently reflect opinions about the specific setting in which they are administered.  相似文献
