A developmentally disabled person should be treated at all times as a unique individual and not as some anonymous "disabled person." The developmentally disabled should not be subjected to invasive medical treatment that is unduly burdensome or nonbeneficial, or be forced to endure a quality of life not meaningful to them as individuals. They have a right to refuse or accept treatment that a surrogate must exercise on behalf of each individual in a responsible and careful manner. Three cases and a preliminary approach to the ethical analysis of decisions to allow developmentally disabled persons to die by forgoing medical treatment are offered. The "best interests" of a developmentally disabled individual, properly understood, can serve as a useful and ethically defensible standard for determining the ethical propriety of surrogate decision making about forgoing life-sustaining medical treatment of the disabled. 相似文献

Social identity theory (SIT) proposes that the more strongly individuals identify with their group, the less favorable attitudes they hold toward dissimilar groups. In contrast, multicultural theory proposes that affirmation toward one's group--particularly with respect to ethnicity--should correspond with higher levels of acceptance toward dissimilar groups. These competing theories were examined with 486 non-Hispanic White, African American, and Hispanic/Latino university students to determine if support would be found for either theory. Consistent with SIT, levels of ethnic identity correlated significantly with levels of ethnocentrism for Whites and Hispanics but not for African Americans. African Americans obtained significantly higher ethnic identity and self-esteem scores than the other 2 groups. Implications of the findings are discussed. 相似文献

The application of functional neuroimaging to the study of human emotion has yielded valuable data; however, the conclusions
that may be drawn from any one study are limited. We applied novel statistical techniques to the meta-analysis of 106 PET
and fMRI studies of human emotion and tested predictions made by key neuroscientific models. The results demonstrated partial
support for asymmetry accounts. Greater left-sided activity was observed for approach emotions, whereas neural activity associated
with negative/withdrawal emotions was symmetrical. Support was also found for affect program emotion accounts. The activation distributions associated with fear, disgust, and anger differed significantly. These emotions
were most consistently associated in activity in regions associated with selective processing deficits when damaged: the amygdala,
the insula and globus pallidus, and the lateral orbitofrontal cortex, respectively. In contrast, the distributions for happiness
and sadness did not differ. These findings are considered in the context of conceptualizations of the neural correlates of
human emotion. 相似文献

In the current cultural context, clinically trained ministers, lay and ordained, offer themselves to troubled souls through at least three distinct varieties of assistance: pastoral care, pastoral counseling, and pastoral psychotherapy. This essay delineates three accepted disciplines, emphasizing the importance of ascertaining, and perhaps re-evaluating, the particular needs and desires of persons who are in physical, mental, or spiritual distress. "Pastoral care," "pastoral counseling," and "pastoral psychotherapy" each play an important role in fulfilling the traditional mandate for "the cure of souls." 相似文献

The aim of this study was to identify reliable and valid subgroups of spinal pain patients, using data from the Swedish version of the Multidimensional Pain Inventory (MPI-S). A second aim was to test the generalisability of the three patient profiles described in earlier studies on the MPI ("adaptive coper", "dysfunctional" and "interpersonally distressed" patients). The study base consisted of two samples of individuals suffering from long-term, non-specific spinal pain and the results were validated across these samples. Cluster analysis was used to detect distinct groups of patients and the validity of these subgroups was evaluated on variables not used to generate the cluster solution. One subgroup was characterised by lower pain severity, lower interference with everyday activities, lower affective distress and higher life control than the other two subgroups. This patient profile was similar to the MPI adaptive coper patients. A second subgroup resembled the dysfunctional patient profile, thus displaying a worse adjustment to chronic pain than the AC patients. The third patient group reported significantly lower levels of social support from "significant others" than the other subgroups. This patient profile was similar to that of the interpersonally distressed patient group. Taken together, the results support the reliability, validity and generalisability of three subgroups of chronic pain patients derived from the MPI-S. 相似文献

Developmental changes in the kinematics and kinetics underlying balance control were studied in 61 children, 9 months to 10 years of age. The children were classified according to developmental milestones as standers; new, intermediate, and advanced walkers; runners-jumpers; hoppers; gallopers; and skippers. The children experienced support-surface translations of varying size and speed. Children with greater locomotor experience withstood larger balance threats without collapsing or stepping. Analyses of scaled trials (perturbations normalized in size to foot length and center of gravity height) revealed that improvement in balance was not related to initial configuration parameters surrounding the task (degree of crouch or lean). Children with advanced locomotor skills had faster recovery times and relatively larger muscle torques than children with less experience. Relative torque-time histories of the more experienced children began to match the adult response to similar perturbations. With increased experience and changing muscle torque regulatory abilities, balance skills became more robust. 相似文献

The relationship between suicide and birthdays, and suicide and public holidays has been studied from data on 32,291 Danish suicides by persons ages 15 years and older in the 25-year period 1970-1994. Evidence was found to support the theory of the "broken-promise effect" for major public holidays in that there appears to be a postponement of a significant number of suicides from before a holiday until after. The division of holidays into nonworking and (half-time) working days showed that a "holiday effect" could only be found around major public holidays, particularly Christmas, Easter, and Whitsun. The postponing or transpositioning effect is relevant to prevention, especially because of the availability and accessibility of help at the end of and after major public (nonworking) holidays. 相似文献
