The author presents some of the health risks and economic and job insecurities involved in working in the United States. He suggests ways for counselors to amend their practices to accommodate the changing work environment and to help clients prepare for and deal with the economic and physical realities of the job market.  相似文献

Magnitude estimates of haptic extent resulted in positively accelerated psychophysical power function with an exponent of 1.18. However, in two further experiments right-handed male subjects made rating-scale judgements of the combined width of two stimulus blocks. Six widths were used and five replications of the 36 factorial combinations were presented to each subject. In Experiment II both stimuli were out of view and one was held between the thumb and index finger of each hand. In Experiment III one stimulus was held out of view between thumb and finger of the right hand and the second was shown to the subject. Mean ratings in both experiments were fit by a model which assumes that responses are a weighted average of the scale values of the two stimuli (Anderson, 1974a).  相似文献

Memory for frequently encountered road signs was investigated. In Experiment 1, the average level of recall of road sign features was found to be only 47%. In Experiment 2, more left-handed than righthanded people recalled that a walking figure faces right on one sign, whereas more right-handed than left-handed people recalled that a digging figure faces left on another sign. Performance thus reflected not a difference in level of mnemonic ability between left-handed and right-handed groups but instead the compatibility between group and task. In Experiment 3, participants were asked to draw any figure walking and any figure digging, with a pattern of results similar to that of Experiment 2. It is suggested that handedness effects in recall are mediated by motor imagery.  相似文献

Many academics extol chaos theory and the science of complexity as significant scientific advances with application in such diverse fields as biology, anthropology, economics, and history. In this paper we focus our attention on structure-within-chaos and the dynamic self-organization of complex systems in the context of social philosophy. Although the modern formulation of the science of complexity has developed out of late-twentieth-century physics and computational mathematics, its roots may extend much deeper into classical thinking. We argue here that the essential ideas and predictions of the science of complexity are found within the social ordering principle of li (the rites) in Confucius's Analects .  相似文献
