This report examines 174 young children's language outcomes in the Bucharest Early Intervention Project, the first randomized trial of foster placement after institutional care. Age of foster placement was highly correlated with language outcomes. Placement by 15 months led to similar expressive and receptive language test scores as typical age peers at 30 and 42 months. Placement from 15 to 24 months also led to dramatic language improvement. In contrast, children placed after 24 months had the same severe language delays as children in institutional care. Language samples at 42 months confirmed that placement after 24 months led to lower expressive skill. 相似文献

Sports characterized by little or moderate weight bearing or impact have a low osteogenic effect. However, the action of such sports on bone turnover remains unclear. The objective of this study was to determine the effect on bone remodelling of physical activities that induce moderate external loading on the skeleton. Thirty-eight male athletes aged 18–39 years (cyclists, n?=?11; swimmers, n?=?13; triathletes, n?=?14) and 10 age-matched sedentary controls aged 22–35 years participated in the study. The study combined measurement of bone mineral density by dual-energy X-ray absorptiometry and bone turnover assessment from specific biochemical markers: serum bone-specific alkaline phosphatase, osteocalcin, urinary type I collagen C-telopeptide and calcium. Compared with the controls and swimmers, adjusted bone mineral density was higher (P?<?0.05) in triathletes at the total proximal femur and lower limbs. No differences in bone mineral density were found between cyclists, swimmers and controls. Compared with controls, osteocalcin was higher (P?<?0.05) in triathletes and swimmers and urinary type I collagen C-telopeptide was higher in swimmers only. Serum bone-specific alkaline phosphatase was lower (P?<?0.05) in cyclists than in all other groups. In conclusion, an osteogenic effect was found only in triathletes, mainly at bone sites under high mechanical stress. Bone turnover differed in athletes compared with controls, suggesting that bone turnover may be sport-practice dependent. Despite some encouraging observations, it was not possible to show that changes in the bone remodelling process were sport-discipline dependent. 相似文献

《野草》主题的佛学解读 总被引：2，自引：0，他引：2

《野草》主题隐含着一个与佛学苦、空观相吻合的逻辑层次。在现世苦难的打击下,鲁迅常常觉得唯“黑暗与虚无”乃是“实有”,佛学无常无我价值观促使他走向“绝望之为虚妄,正与希望相同”的空无状态。由空开拓出生命的抗争之路,承担起现世世界扫滞除执、反抗绝望的责任是《野草》哲学的关键。诗文吸收佛教勇猛精进的精神,同时消解了佛教因果轮回的唯心思想。 相似文献

Abstract The applications of network technology to pre-service and in-service teacher training are wide in scope but may nevertheless be grouped into two broad categories: the network as a source of assistance (or self-help) for teachers during the classroom transfer of knowledge which they have gained on an on-site training course; and the network as an environment where the training process actually takes place. This article describes the study of a mixed on-site/on-line approach adopted for a training course called EDIT (EDucating with Internet and Telematics); the topic of the course itself was the use of the Internet to support teaching. The distinguishing feature of the approach used is the alternation between complementary on-site training and on-line activities. 相似文献

This contribution considers a variety of aspects of the bloodstock breeding world during the three decades following World War Two, focusing in particular on the breeders of thoroughbred horses and the attitudes of those breeders towards their calling. It is argued that even at this late stage of its history, the persistence of the Corinthian amateur ideal, a dogged indifference to the realities of social and economic change, and a high degree of institutional social exclusiveness was in part responsible for the relative decline of what had been, in the inter-war years, the world's pre-eminent bloodstock industry. 相似文献
