Anticipating the reevaluation of the Dutch organ procurement system, in late 2003 the Rathenau Institute published a study entitled 'Gift or Contribution?' In this study, the author, Govert den Hartogh, carries out a thorough moral analysis of the problem of organ shortage and fair allocation of organs. He suggests there should be a change in mentality whereby organ donation is no longer viewed in terms of charity and the volunteer spirit, but rather in terms of duty and reciprocity. The procurement and allocation of donor organs should be seen as a system of mutually assured help. Fair allocation would imply to give priority to those who recognize and comply with their duty: the registered donors. The idea of viewing organ donation as an undertaking involving mutual benefit rather than as a matter of charity, however, is not new. Notwithstanding the fact that reference to charity and altruism is not required in order for the organ donation to be of moral significance, we will argue against the reciprocity-based scenario. Steering organ allocation towards those who are themselves willing to donate organs is both an ineffective and morally questionable means of attempting to counter organ shortage.  相似文献

We have determined that the temporal context of drinking can modulate latent inhibition of learned saline aversions in Wistar rats by changing the time of day of drinking of the preexposure and conditioning phases. Latent inhibition was absent in the group preexposed and conditioned to saline at different times of the day, but not in the group that was preexposed and conditioned at the same time of day. The results confirm a previous report that the time of day can modulate taste aversion learning independently of other environmental cues. It is proposed that the features and duration of the habituation training to the temporal contexts used may be critical for time-dependent latent inhibition to appear.  相似文献

Four dual-task experiments are reported in which a short-term memory task is performed concurrently with a random interval repetition task, which was designed to interfere with functions normally attributed to the central executive in the working memory model of Baddeley and Hitch (1974). The task was found to interfere with supra-span serial recall and with backward memory span, but did not disrupt performance on a forward-memoryspan task. The effects were observed in dissociation with effects of articulatory suppression and matrix tapping, so that the locus of the effects of the new task is not due to the slave systems. In addition, single-task random-interval repetition performance was sampled and compared to performance in the dual-task conditions of all four experiments. Although quality of tapping performance differed between the single-task and the dual-task conditions, it was not related to recall performance. All the results are discussed with reference to the working memory model.  相似文献

Negative behavioral contrast on multiple treadle-press schedules   总被引:2,自引:2,他引:0       下载免费PDF全文
Eight pigeons pressed treadles for food reinforcers delivered by several multiple variable-interval schedules. The rate of reinforcement for responding during one component schedule was held constant at 30 reinforcers per hour. The rate of reinforcement for responding during the other component varied from 0 to 120 or 240 reinforcers per hour. The schedules were presented in different orders for different subjects. The rate of responding emitted during the variable component schedule varied directly with the rate of reinforcement it provided. The rate of responding during the constant component did not increase consistently when the rate of reinforcement obtained from the variable component decreased from 30 to 0 reinforcers per hr. The rate of responding emitted during the constant component decreased when the rate of reinforcement obtained from the variable component increased from 30 reinforcers per hour to a higher rate. That is, negative but not positive behavioral contrast occurred. The failure to find positive contrast is consistent with one of the predictions of the additive theories of behavioral contrast. Finding negative contrast has ambiguous implications for the additive theories.  相似文献

Two experiments examined the reactions of victims of disadvantage to compensation designed to improve their lot. In Experiment 1, subjects participated in an organizational simulation where they were disadvantaged with respect to their pay. Subsequently, a third party intervened with one of a number of strategies which varied according to whether or not the subjects received compensation and whether or not the person responsible for their disadvantage suffered. The interaction between compensation and suffering was significant on a satisfaction measure and the pattern indicated that subjects were most satisfied when the harmdoer suffered to provide compensation. This interaction was not significant on a measure of perceptions of fairness. Experiment 2 examined the possibility that the intervention of the third party in Experiment 1 may have created feelings of indebtedness. In a similar paradigm, subjects were either disadvantaged by a harmdoer or by external events and received compensation that either was or was not accompanied by a request for repayment. When subjects had been disadvantaged by external events, they were more satisfied and felt more fairly treated when there was an opportunity for reciprocation than when there was not, while the opposite pattern was the case when the harmdoer was responsible for the disadvantage. The results were discussed in the context of the complexity of the receipt of aid phenomenon and possible implications for the design of ameliorative social programs.  相似文献

This article is a response to D. A. Helminiak's (2001) “Treating Spiritual Issues in Secular Psychotherapy” from the perspective of K. Wilber's integral psychology. The article consists of 3 sections: (a) a selective summary of integral psychology, including the perennial philosophy, 10 levels of development, lines of development, temporary states, types of orientations, the self, and the 4 quadrants; (b) various conceptual issues; and (c) usefulness to mental health practitioners (MHPs). Although D. A. Helminiak's endeavor to formulate a clear and functional definition of spirituality is commended, his claim of novelty is shown to be unwarranted. It is argued that K. Wilber's integral model is more comprehensive, clear, coherent, and helpful to MHPs.  相似文献

In this article the authors describe the program of the Hospital Real y General de Nuestra Señora de Gracia in Saragossa (Spain) and its importance in the history of occupational therapy. It is believed to be the first hospital in the world to use occupations as therapy for psychiatric patients. Pinel knew about this new trend through a report by Iberti and wrote about it in his book Medico-Philosophical Treatise on Mental Alienation.  相似文献

Biallelic germline mutations in mismatch repair genes predispose to constitutional mismatch repair deficiency syndrome (CMMR-D). The condition is characterized by a broad spectrum of early-onset tumors, including hematological, brain and bowel and is frequently associated with features of Neurofibromatosis type 1. Few definitive screening recommendations have been suggested and no published reports have described predictive testing. We report on the first case of predictive testing for CMMR-D following the identification of two non-consanguineous parents, with the same heterozygous mutation in MLH1: c.1528C > T. The genetic counseling offered to the family, for their two at-risk daughters, is discussed with a focus on the ethical considerations of testing children for known cancer-causing variants. The challenges that are encountered when reporting on heterozygosity in a child younger than 18 years (disclosure of carrier status and risk for Lynch syndrome), when discovered during testing for homozygosity, are addressed. In addition, the identification of CMMR-D in a three year old, and the recommended clinical surveillance that was proposed for this individual is discussed. Despite predictive testing and presymptomatic screening, the sudden death of the child with CMMR-D syndrome occurred 6 months after her last surveillance MRI. This report further highlights the difficulty of developing guidelines, as a result of the rarity of cases and diversity of presentation.  相似文献
