Medical technology has made tremendous strides in extending the lives of patients who have suffered organ failure. Machines can now replace the function of the kidneys, the heart, and other vital organs. Much has been written about a patient's right to refuse or direct the withdrawal of medical treatment, especially at the end of life, under the guise of “death with dignity.” However, little attention has been paid to the situation where a patient elects to deactivate their life-sustaining medical device without a physician's involvement. This raises the challenging question of whether the patient's manner of death should be classified as suicide or natural. Surprisingly, common law, statutes, medical ethics, and public health practice are not in alignment on the answer. This article will explore the ramifications and far-reaching impact that such divergence has on the survivors and the medical community, as well as recommend corrective actions and practical approaches for the medical and legal practitioner. 相似文献

A family relations model for the study of adolescent egocentrism was tested in an exploratory study of the relationship between parental socialization styles and adolescents' imaginary audience behavior. A sample of adolescent boys (n=58) and girls (n=57) responded to Heilbrun's Parent-Child Interaction Rating Scale and Schaefer's Parent-Behavior Inventory and completed Elkind and Bowen's Imaginary Audience Scale. As hypothesized, rejection-control was associated with increased imaginary audience behavior, while physical affect was negatively related to self-consciousness. Sex differences were noted, with rejection-control being most important in predicting self-consciousness for boys and physical affect being the best predictor of girls' egocentrism behavior. The data provide an alternative model to a cognitive developmental perspective of adolescent egocentrism development.Research was partially supported through the Western Regional Research Project W-144, Development of Social Competency in Children, with funding in part from the Science and Education Administration/Cooperative Research of USDA, and the Utah State University Agricultural Experiment Station.Received his M.A. in psychology from the University of Nebraska at Omaha and Ph.D. in human development from the Pennsylvania State University.

Two theoretical perspectives have been advanced to account for heightened egocentrism during early adolescence. One perspective assumes that formal operational thought is associated with increased self-consciousness. The second perspective proposes that parental support and affection diminish egocentrism, while parental rejection enhances self-conscious reactions by young adolescents. Data analysis using responses from 251 early adolescents (131 males, 120 females) on measures of cognitive development and perceived parental support revealed that (a) formal operations diminished adolescent egocentrism, while (b) perceived parental relations were predictive of self-consciousness. Contrary to posttheoretical assumptions, seventh graders functioning at the level of concrete operations were higher in self-conscious egocentrism than were formal-operations youths. Further, perceived parental support was associated with diminished egocentrism, while perceived parental rejection was predictive of heightened self-consciousness.Her research interests focus on early adolescent development.His research interests focus on personality and social development during adolescence.His research interests focus on clinical and counseling psychology and psychotherapy. 相似文献

The primary goal of this research is to examine the overall utility of nonradiographic dental records for the establishment of individual identifications. It was found that even without radiographic lines of comparison, charts and notes that accurately detail a missing individual's antemortem dental condition can be essential for establishing an identification. Based on an analysis of two large datasets, individual dental patterns were determined to be generally unique, or at least very uncommon. Through this type of empirical comparison, it is possible to establish a strong, quantifiable association with a missing individual. The results of this research indicate that a definitive number of points of concordance do not need to be established in dental identification cases. Each case must be assessed individually. The critical factor is to remove subjective judgment calls from dental comparisons. This research has proposed a new method of empirical comparison that allows forensic odontologists to derive objective frequency information regarding the occurrence of specific dental patterns in the general population. The method is similar to that used for mtDNA casework, and a computer program (OdontoSearch) has been developed to make the technique accessible. It was found that even a small number of common dental characteristics may produce a very rare dental pattern, a point that may be counterintuitive to many forensic odontologists. 相似文献
