Genetic testing in minor children presents a complex ethical and social problem. Current guidelines state that genetic testing of children is recommended only under circumstances where a clear medical or psychosocial benefit to the child can be demonstrated. Because of the difficulty in determining a psychosocial benefit, the discussion about genetic testing of minors ultimately tends to focus on who has the right to make the decision and whose right to autonomy is jeopardized, the parent's or the child's, when there is no identified medical benefit. Historically, a western bioethics paradigm, Principlism, has been used to guide genetic counseling sessions and genetic-testing guidelines for minors. This bioethics paradigm is guided by the principles: respect for autonomy, beneficence, nonmaleficence, and justice. Genetic testing in children, when viewed through a traditional bioethics filter is limited by its focus on the individual because children are not only individuals, they are also integral parts of a larger social context, that of their family. Because this bioethics paradigm places a strong emphasis on individual autonomy, the family's beliefs and values and the parents' concern for their children may be overshadowed by the medical community's attempt to preserve the child's "right" to an autonomous decision about genetic testing. The purpose of this paper is to present a theoretical and ethics-based conceptual framework that may be useful in the development of genetic counseling interventions.  相似文献

This study extends the data on the efficacy of cognitive interventions for patients with chronic medical problems and describes the case of a 37-year-old woman with an anxiety disorder related to diabetes. The effects on panic frequency, use of safety behaviour and related beliefs were investigated after the introduction of two main cognitive-behavioral interventions. The results are consistent with predictions from the cognitive model of panic. This case demonstrates the usefulness of directly challenging the 'meaning' of the feared situation in order to produce clinically significant improvements in the management of physical disease.  相似文献

The endowment effect occurs when ownership of a good leads consumers to value the good more than its market value. Students who were given College of Business Administration insignia mugs to keep valued them significantly more than students who were given the same mugs to examine and return (nonendowment condition). The endowment effect also occurred for plain white mugs. Students who were given plain white mugs to keep valued them more than students who were given the same mugs to examine and return. Ownership of insignia mugs not only resulted in the endowment effect but also resulted in an institutional affinity effect: Students provided higher satisfaction ratings with the College of Business Administration than did students endowed with plain white mugs and students in nonendowed conditions. This study demonstrates the impact of the endowment effect on institutional affinity for insignia goods. However, the tandem endowment-affinity effect occurs at the attitude formation stage, not when an attitude has already been formed.  相似文献

Lawyers are often called upon by their older clients to draft contracts, make up wills or powers of attorney, or provide other forms of legal advice or service. With the increasing numbers of older people in the population, the numbers of older clients for legal practitioners is likely to increase. Older people are also at increased risk for impaired cognitive processes that can affect their ability to make reasoned judgements in civil contracts and other legal arrangements. Here we report on the results of a survey of 302 Australian solicitors as to their experience and practices in determining the capacity of older clients to make legal decisions. The responses, reflecting a 20.7% return rate, showed a wide range of experience in conducting capacity assessments, with a mean of 15.7 years (SD = 10.59). There was a very wide range of practices in determining capacity with no consensus. The most frequent form of questions older clients were asked related to personal and family history. Less than one-quarter asked for the rationale of the decision: the most appropriate form of question in the literature. The results suggest a need for further training of solicitors in the assessment of the capacity of older clients to make legal decisions.  相似文献

The effects of aging on response time (RT) are examined in 2 lexical-decision experiments with young and older subjects (age 60-75). The results show that the older subjects were slower than the young subjects, but more accurate. R. Ratcliff s (1978) diffusion model provided a good account of RTs, their distributions, and response accuracy. The fits show an 80-100-ms slowing of the nondecision components of RT for older subjects relative to young subjects and more conservative decision criterion settings for older subjects than for young subjects. The rates of accumulation of evidence were not significantly different for older compared with young subjects (less than 2% and 5% higher for older subjects relative to young subjects in the 2 experiments).  相似文献

This study examined the relationship between biological and social risk factors and aggressive behavior patterns in an Australian high-risk sample of 370 adolescents. Perinatal, temperamental, familial, sociodemographic, and behavioral data were collected during interviews completed during pregnancy. immediately postpartum, and when the children were 6 months old and 5, 14, and 15 years old. Youths were given tests of verbal and neuropsychological functioning at the age 5 and age 15 follow-ups. Youths were divided into early-onset persistent aggression, adolescent-onset aggression, and nonaggressive behavior groups. Results revealed that the interaction of biological and social risk factors was significantly related to early-onset persistent aggression. Gender and developmental phase of measurement moderated the relationship between biosocial risks and the outcomes of early-onset persistent aggression and adolescent-onset aggression.  相似文献

It is commonly assumed across the language sciences that some semantic participant information is lexically encoded in the representation of verbs and some is not. In this paper, we propose that semantic obligatoriness and verb class specificity are criteria which influence whether semantic information is lexically encoded. We present a comprehensive survey of the English verbal lexicon, a sentence continuation study, and an on-line sentence processing study which confirm that both factors play a role in the lexical encoding of participant information.  相似文献

Previous work on the matching law has predominantly focused on the molar effects of the contingency by examining only one reinforcer ratio for extended periods. Responses are distributed as a function of reinforcer ratios under these static conditions. But the outcome under a dynamic condition in which reinforcer ratios change continuously has not been determined. The present study implemented concurrent variable-interval schedules that changed continuously across a fixed 5-min trial. The schedules were reciprocally interlocked. The variable interval for one key changed continuously from a variable-interval 15-s to a variable-interval 480-s, while the schedule for the other key changed from a variable-interval 480-s to a variable-interval 15-s. This dynamical concurrent schedule shifted behavior in the direction of matching response ratios to reinforcer ratios. Sensitivities derived from the generalized matching law were approximately 0.62, the mean absolute bias was approximately 0.11, and r2s were approximately 0.86. It was concluded that choice behavior can come to adapt to reinforcer ratios that change continuously over a relatively short time and that this change does not require extensive experience with a fixed reinforcer ratio. The results were seen as supportive of the view that all behavior constitutes choice.  相似文献

Pastoral theology needs to clarify its identity as an autonomous theological discipline by developing its own knowledge base, body of research, and practice methods. It needs to broaden its scope to include not only a concern for personal issues, but also larger sociocultural and anthropological ones as well. Additionally, there is a pressing need for moving beyond the confines of traditional methods of correlation. This essay offers a new method for pastoral theological reflection and practice that is grounded in Hans-Georg Gadamer's understanding of aesthetic truth and hermeneutics. It offers a new way of conceptualizing the relationship of pastoral theology to such conversation partners as the Bible and theological tradition, the social sciences, and practical wisdom, demonstrating how these can contribute to the pastoral theological task.  相似文献
