Reported incidence of clergy sexual misconduct is on the rise in the Christian church. This article reviews the literature describing those individuals involved in such misconduct. Included in this review are the characteristics of clergy, mostly men, who perpetrate the sexual abuse of others and an overview of the individuals, mostly women, who are victimized. An examination of the repercussions of this type of power abuse is included. Finally, a brief review describes what is being done by two Christian churches faced with clergy who have committed sexual misconduct.  相似文献

Administration of the pituitary hormone, arginine vasopressin (AVP), enhances memory in animals and humans. Since AVP is the antidiuretic hormone, its release can be inferred from reductions in urine flow. Forty-six male adults recalled the contents of a complex story and then either were exposed to achievement arousal or were not. Significantly more of the subjects in the aroused than the nonaroused condition showed a decrease in urine flow, and the greater the decrease in urine flow among the achievement-aroused subjects, the better the recall of achievement-related story content 24 hours later. Subjects high inn Achievement, in the achievement-oriented condition, showed lower urine output at the outset of the second day and greater improvement in learning to unscramble words. Since lower urine output was also related to improvement in unscrambling words, achievement arousal may have released AVP which in turn may have facilitated achievement-related retention and performance.I am greatly indebted to Sean Connelly for assistance in carrying out this research and to Dr. Franklin Epstein of the Beth Israel Hospital, Boston, for helping me to understand how the kidney functions in producing urine.  相似文献

Although traditionally associated with Parkinsons disease, the eosinophilic intracytoplasmic neuronal inclusion known as the Lewy body has recently been regarded as the primary neuropathologic finding in a variety of conditions affecting the aging brain. The term Lewy Body Disease (LBD) will be used in this review to refer to a spectrum of clinical states varying from those due to incidental or mildly symptomatic histopathologic changes to progressive dementia and psychosis. Many unanswered questions remain about the neurobehavioral and neuropathological implications of Lewy bodies, but it is useful to consider the LED spectrum in terms of the variable effects on neuropsychiatric function that can be observed clinically.  相似文献

To further test role constraint and socialization theories of gender differences in coping, two studies were conducted to examine coping strategies in individuals occupying similar roles. The relations between coping strategy frequency and effectiveness and between coping strategy use and psychological functioning also were examined. Predominantly Caucasian female and male college students participated in the studies. Results indicated support for both socialization and role constraint theories. Effectiveness and frequency of coping strategy use were moderately correlated. Gender differences in cognitive appraisal varied with dispositional vs. situational assessment. The need for a more integrated model to explain gender differences in coping and implications for existing theories are discussed.  相似文献

PHONOLOGICAL CODES ARE AUTOMATICALLY ACTIVATED DURING READING:   总被引:4,自引:0,他引:4  
Abstract— Subjects read sentences containing target words that were homophones (words with a single pronunciation but different spellings) while their eye movements were recorded A prime word was presented briefly at the onset of fixation on the target region The prime for a given target (e g, beach) was either identical to the target (beach, a phonologically similar word (the homophone beech), a visually similar nonhomophone (bench), or a dissimilar word (noise) Phonological priming effects were assessed by comparing fixation times on the target when It was preceded by the homophone versus the visually similar word Results suggest that phonological codes are automatically activated during eye fixations in reading  相似文献

PREFERENCE REVERSALS DUE TO MYOPIC DISCOUNTING OF DELAYED REWARD   总被引:7,自引:0,他引:7  
Abstract— A basic stationarity axiom of economic theory assumes stable preference between two deferred goods separated by a fixed time. To test this assumption, we offered subjects choices between delayed rewards, while manipulating the delays to those rewards. Preferences typically reversed with changes in delay, as predicted by hyperbolic discounting models of impulsiveness. Of 36 subjects, 34 reversed preference from a larger, later reward to a smaller, earlier reward as the delays to both rewards decreased. We conclude that the stationarity axiom is not appropriate in models of human choice.  相似文献
