There is limited empirical research on the correlates of conduct problems (CP) and depression comorbidity during childhood. This study investigated 479 elementary school children (48.2% girls). It compared children with comorbidity to children with CP only, depression only, and control children on individual, academic, social, and family characteristics. The study also analyzed gender differences in the associations between correlates and comorbidity. Multinomial logistic regression results revealed that children with CP and depression had higher levels of anxiety and more school difficulties than children with CP only, more social difficulties and more severe attention deficit and hyperactivity disorder (ADHD) symptoms than children with depression only, and more difficulties in all domains than control children. Girls with CP and depression presented a particularly negative profile, including lower school abilities than CP and control girls, and lower social skills and more severe ADHD symptoms than control girls. Implications for evaluation and intervention planning are discussed. 相似文献

Home environment quality is a well-known predictor of school readiness (SR), although the underlying processes are little known. This study tested two hypotheses: (a) child language mediates the association between home characteristics (socioeconomic status and exposure to reading) and SR, and (b) genetic factors partly explain the association between language and SR. Data were collected between 6 and 63 months in a large sample of twins. Results showed that home characteristics had direct effects on SR and indirect effects through child language. No genetic correlation was found between language and SR. These results suggest that home characteristics affect SR in part through their effect on early language skills, and show that this process is mainly environmental rather than genetic in nature. 相似文献

The genetic-environmental etiology of cognitive school readiness and later academic achievement in early childhood 总被引：1，自引：0，他引：1

Using a genetic design of 840 60-month-old twins, this study investigated the genetic and environmental contributions to (a) individual differences in four components of cognitive school readiness, (b) the general ability underlying these four components, and (c) the predictive association between school readiness and school achievement. Results revealed that the contribution of the shared environment for cognitive school readiness was substantial. Genetic effects were more important for the core abilities underlying school readiness than for each specific skill, although shared environment remained the largest factor overall. Genetic, shared, and nonshared environmental factors all accounted for the predictive association between school readiness and early school achievement. These results contribute to a better understanding of the early determinants of school readiness. 相似文献

Students with conduct problems (CPs) may present heterogeneity in terms of behavioral manifestations and service needs. Previous studies using Latent Class Analysis (LCA) to capture this heterogeneity have been conducted mostly with community samples and have often applied a narrow definition of CP. Considering this context, this study investigated CP subgroups among elementary students with CP receiving special education services. LCA was conducted on 10 CP indices for 297 6–9 year old children. Latent CP subgroups were compared with 201 controls without CP. LCA suggests a three‐class solution based on severity of CP and context/informant reports (home/parent, school/teacher). Multinomial logistic regressions indicated that all CP subgroups differed from the control group on social competence and surgency/extraversion temperament scale in the expected direction but varied on specific personal, family, or school correlates. Interventions aimed at reducing CP should consider differences in CP subtype and in correlated risk factors. 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
孟宏峰 《内蒙古师范大学学报(哲学社会科学版)》2005,34(3):97-101
《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

This article examines approaches to creating museum Web sites that offer quality experiences to online users. In six case studies, museum Web developers in the U.S. and Canada describe how they have made the most of available human and financial resources. The development history of each site offers insights into the origins of a design and its subsequent versions, and describes the influence of institutional missions, philosophies, success indicators—and financial and human resources, the most crucial factors. The study found considerable variety in the backgrounds, expertise, titles and training of people developing Web sites within institutions. Web teams developed “exchange” experiences through online discussion, and by creating links among users, or between museum staff and users. In three case studies, Web sites encouraged visitors to cycle between online and on‐site museum visits. Web developers describe using quantitative and qualitative online audience research strategies. WebTrendsTM software has enabled Web teams to report complex log analyses. Creating online experiences in partnership with users is the intention of Web developers. 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
