This article is a review of the world-wide efforts of clinicians and researchers in the area of diagnosis, treatment, and prevention of multiple substance abuse. Represented are studies in cross-cultural prevention research and substance abuse which address the new and burgeoning area of clinical prevention research from a multidisciplinary perspective. The article also discusses the theory and methods in prevention in New York City, Israel, Italy, Spain, and in Cali, Columbia. The authors hope that this information will result in greater recognition for the need to understand effective measures of drug prevention, and to develop new research directions which shall enrich and enhance our present state of knowledge in substance abuse prevention programming.  相似文献

Editorial note:The following bibliographic survey of computer ethics is intended as a general introduction useful to guide both preliminary research and course development. It is the first of a series that Carl Mitcham will be doing on a number of specific discussions of ethics in science and technology. Future installments are projected on nuclear ethics, engineering ethics, ethics in scientific research, and biomedical ethics. With this [book] I issue “a call to arms.” The world needs much more discussion and writing on the social and ethical issues surrounding computing. I hope readers .... will take up the challenge.  相似文献

A pragmatic existential therapy was developed to help patients stuck in intractable life situations make the psychic turn of death camp survivors who learned to adapt to savage conditions in extremity. Using a model of absurd heroism inimical to therapies seeking to modify intrapsychic dynamics, this hardminded intervention thematizes (a) the clinical activation of biological intelligence; (b) reconciliation with the existential situation; (c) problem-solving; (d) therapeutic shaping of realistic, life-affirming attitudes; and (e) absurd happiness. Phenomenological evidence of the survivors' existential posture is drawn from death camp literature, while a comparative case application features a patient afflicted with neurofibromatosis.  相似文献

The effects of several different schedules of primary reinforcement were compared in a picture-naming task with retarded children. In Experiment I, number of correct responses and learning rate were higher under fixed-ratio schedules than under continuous reinforcement. In Experiment II, number of correct responses and learning rate tended to be greater under intermediate than under low or high fixed-ratio schedules. In Experiment III, number of correct responses was higher under interlocking schedules, in which the response requirement increased with time following the previous reinforcement, than under comparable fixed-ratio schedules. Learning rates were generally low and, perhaps because of this, not very different under the two types of schedules in this experiment. Accuracy (i.e., proportion of trials on which correct responses occurred) was typically high and insensitive to variations in schedule and schedule parameter throughout each experiment.  相似文献

Two groups of subjects adapted to prismatic displacement. One adapted in a visual target condition, in which they pointed to an external visual target with their right index fingers. The other adapted in a body target condition, in which they pointed to their left index fingers with their right index fingers. The visual target group showed more adaptation of the right hand and less adaptation of the left hand than did the body target group. These results are consistent with an assimilation tendency within the proprioceptive modality, namely that body parts that are in contact tend to be perceived as occupying the same spatial position.  相似文献
