Mental health clinicians, charged with treating a growing number of incestuous daughters, have little empirical data on which to base their clinical judgments. The present study explored the hypotheses of child psychiatrists on the impact of incest. The results suggest that these clinicians view incest as almost always causing serious psychological disorder. While there appears to be little agreement on the nature of acute sequela, disturbed heterosexual functioning was frequently cited as a long-term consequence. In addition, the results suggest that psychiatrists consider factors related to the make-up of the incestuous family, and not the actual sexual behavior, as most pathogenic. The implications of the present results for future research are discussed.  相似文献

面对“实践美学终结论”的冲击,朱立元主张从实践存在论出发建构美学理论,初步形成了“实践存在论美学”思想。“实践存在论美学”从实践的概念入手,认为实践原本是作为人的存在方式来理解的人生实践,应从存在论角度理解和阐释实践。由此,实践美学应以实践论与存在论的结合作为哲学基础,走向“实践存在论美学”。“实践存在论美学”包括三大基本思想:美是生成的而不是现成的,审美活动是一种基本的人生实践,审美是一种高级的人生境界。  相似文献

The study examined whether age, prior work experience, number of courses taken, and number of internship hours have a positive relationship with counseling self‐efficacy. Participants were 116 counselor education students. The results from correlation and multivariate analyses of covariance revealed that the length of internship hours and prior related work experience were positively correlated with counseling self‐efficacy. The differences in counseling anxiety, affection adjustment, and assessment found between the students in programs accredited by the Council for Accreditation of Counseling and Related Educational Programs (CACREP) and those in non‐CACREP‐accredited programs disappeared when the background variables were controlled as covariates.  相似文献

The aim of the study was to investigate age and sex differences in performance in an 11‐plus selective examination. The sample was made up of 3460 pupils who were born in 1981 and who had sat the examination for the first time. Results based on a data set consisting of raw scores in Maltese, English, mathematics, social studies and religious knowledge showed a strong and consistent age effect in all five attainment measures: performance decreased with age from the ‘oldest’ pupils to the youngest’. In regard to sex differences, girls outperformed boys in Maltese, English and religion, with differences being most marked in the two languages. The performance of the two sexes in mathematics and social studies was very similar, with the boys’ performance being slightly, but not significantly, better. These age and sex effects were also evident in the proportions of pupils who passed or failed the examination. Older pupils tended to be more successful than younger pupils, and girls were more likely to pass the examination than boys.  相似文献
