A common problem in ethics is that people often desire an end but fail to take the means necessary to achieve it. Employers and employees may desire the safety end mandated by performance standards for pollution control, but they may fail to employ the means, specification standards, necessary to achieve this end. This article argues that current (de jure) performance standards, for lowering employee exposures to ionizing radiation, fail to promote de facto worker welfare, in part because employers and employees do not follow the necessary means (practices known as specification standards) to achieve the end (performance standards) of workplace safety. To support this conclusion, the article argues that (1) safety requires attention to specification, as well as performance, standards; (2) coal-mine specification standards may fail to promote performance standards; (3) nuclear workplace standards may do the same; (4) choosing appropriate means to the end of safety requires attention to the ways uncertainties and variations in exposure may mask violations of standards; and (5) correcting regulatory inattention to differences between de jure and de facto is necessary for achievement of ethical goals for safety.  相似文献

The Colombian pension reform of 1994 introduced a privately administered defined–contribution programme, which coexists with a reformed public defined–benefit programme. This paper gives an overview of the Colombian pension system and evaluates its performance using four criteria: (1) effectiveness, (2) efficiency, (3) equity, and (4) sustainability, finding evidence of severe shortcomings. Both effective coverage and benefit levels are low, costs in the private programme are high, and there is evidence that insured persons are not fully informed about the actual system. The system is inequitable and the uninsured population bears part of the financial burden. The public programme is financially not sustainable. A current reform proposal from the Colombian government addresses only part of the problem.  相似文献

Identifying patterns of fearful behaviors early and accurately is essential to identify children who may be at increased risk for psychopathology. Previous work focused on the total amount of fear by using composites across time. However, considering the temporal dynamics of fear expression might offer novel insights into the identification of children at risk. One hundred and twenty‐five toddlers participated in high‐ and low‐fear tasks. Data were modeled using a novel two‐step approach. First, a hidden Markov model estimated latent fear states and transitions across states over time. Results revealed children's behavior was best represented by six behavioral states. Next, these states were analyzed using sequence clustering to identify groups of children with similar dynamic trajectories through the states. A four‐cluster solution found groups of children varied in fear response and regulation process: “external regulators” (using the caregiver as a regulation tool), “low reactive” (low reaction to stimulus), “fearful explorers” (managing their own internal state with minimal assistance from the caregiver), and “high fear” (fearful/at‐caregiver state regardless of task). The combination of analytic tools enabled fine‐grained examination of the processes of fearful temperament. These insights may help prevention programs target behaviors that perpetuate anxious behavior in the moment.  相似文献

The Health Behaviour in School-Aged Children survey contains scales intended to measure life satisfaction, mental health problems and socioeconomic status. This article takes inspiration from science and technology studies and analyse the survey as performative. It also examines subjective meaning-making through an analysis of interviews with 15-year-old teenagers. It shows how the survey enacts the subject position of an accountable teenager and how teenagers experience the survey as sending a message about how one should live. While some teenagers experience this as positive, others narrate feelings of shame. This could be interpreted as a way for them to be accountable for themselves.  相似文献
