Judicial decisions reviewed in this article indicate that courts have taken two disparate approaches to disputes over futility of treatment. To explore whether a consensus on medical futility is developing among hospitals, the authors conducted a nationwide survey of health care professionals at hospitals. Respondents assigned importance ratings to factors used in recent futility decisions made at their institutions. The resulting importance ratings showed significant variation by characteristics of the institution (comparing respondents from for-profit, not-for-profit, and government hospitals) and by profession of the respondent (comparing physicians and nurses). The respondents' judgments endorsed three distinct strategies for making futility decisions (i.e., emphasis on the patient's decision preferences, providing for the patient and family, and adhering to objective medical and social norms). © 1998 John Wiley & Sons, Ltd.  相似文献

The hypothesis that dreaming is mediated by the right hemisphere was evaluated by monitoring EEG power asymmetry during REM and NREM sleep, and obtaining mentation reports when short-term temporal shifts in the EEG indicated relative left- or right-hemispheric dominance. Content analyses provided no support for the right-hemisphere hypothesis; indeed, some scales showed higher content during relative left-hemispheric dominance. In contrast to earlier reports, no difference between REM and NREM in EEG asymmetry was observed.  相似文献

The authors discuss the development of the concept of prevention as it has evolved from the public health and mental health fields. Concepts of epidemiology, treatment, and community mental health are defined in terms of their contributions to the evolution of prevention thinking. Four models of prevention are presented and critiqued: the public health model, the operational model, the antecedent conditions model, and the injury control model. Essential ingredients for implementing effective preventive interventions are presented, as well as examples of practical preventive interventions.  相似文献

This paper identifies rational orderliness and moral appropriateness as 2 norms that the United States Constitution requires for sentencing in capital murder trials. The courts convey these norms directly to jurors through jury instructions in the penalty phase of capital murder trials. To follow the instructions, jurors require accurate declarative knowledge (rules of law) and procedural knowledge (processes required to execute the rules) of state and federal sentencing law. Undergraduate mock jurors showed low accuracy for both types of knowledge after reviewing and listening to pattern jury instructions. Participants failed to offset aggravating factors with mitigating circumstances as the Missouri Approved Jury Instructions direct. The less knowledge that participants mastered about mitigation, the more certain they were of invoking the death penalty.  相似文献

Research into the effects of cognitive aging on route navigation usually focuses on differences in learning performance. In contrast, we investigated age-related differences in route knowledge after successful route learning. One young and two groups of older adults categorized using different cut-off scores on the Montreal Cognitive Assessment (MoCA), were trained until they could correctly recall short routes. During the test phase, they were asked to recall the sequence in which landmarks were encountered (Landmark Sequence Task), the sequence of turns (Direction Sequence Task), the direction of turn at each landmark (Landmark Direction Task), and to identify the learned routes from a map perspective (Perspective Taking Task). Comparing the young participant group with the older group that scored high on the MoCA, we found effects of typical aging in learning performance and in the Direction Sequence Task. Comparing the two older groups, we found effects of early signs of atypical aging in the Landmark Direction and the Perspective Taking Tasks. We found no differences between groups in the Landmark Sequence Task. Given that participants were able to recall routes after training, these results suggest that typical and early signs of atypical aging result in differential memory deficits for aspects of route knowledge.  相似文献

The authors provide a comprehensive survey of the research literature on pretherapy training for group psychotherapy. The twenty studies identified during the twenty-five-year period 1962–1987 were fraught with various methodological and design inadequacies. Despite the widespread positive endorsement found in the clinical literature, the research evidence for the benefit of pretherapy training is not particularly impressive. While there is evidence of certain immediate effects (e.g., improved attendance), results concerning process and outcome effects are, at best, only suggestive. In the face of the disappointing findings, the authors are nonetheless optimistic regarding the potential value of pretherapy training.  相似文献

The authors describe a range of critical issues that are common within homogeneously composed groups for patients suffering from Acquired Immunodeficiency Syndrome (AIDS) and AIDS Related Complex (ARC). They examine the need for these patients to understand their physical symptomatology, to reconsider life's priorities, and to confront their ethical and moral dilemmas. The authors also highlight special affects, unique group atmosphere and process, and the nature of the group contract that is essential for these patients.  相似文献
