The relation of attachment security to multiple domains of psychosocial functioning was examined in a community sample of 167 early adolescents. Security of attachment organization, assessed using the Adult Attachment Interview, was linked to success in establishing autonomy while maintaining a sense of relatedness both with fathers and with peers, even after accounting for predictions from qualities of the mother-teen relationship. Growth curve analyses revealed links of insecurity to increasing patterns of externalizing behavior and higher and stable patterns of depressive symptoms across adolescence. Implications for a developing theory of the connections of the attachment system to multiple domains of functioning in adolescence are discussed.  相似文献

In this study, we contrast two competing approaches, not previously compared, that balance the rigor of CFA/SEM with the flexibility to fit realistically complex data. Exploratory SEM (ESEM) is claimed to provide an optimal compromise between EFA and CFA/SEM. Alternatively, a family of three Bayesian SEMs (BSEMs) replace fixed-zero estimates with informative, small-variance priors for different subsets of parameters: cross-loadings (CL), residual covariances (RC), or CLs and RCs (CLRC). In Study 1, using three simulation studies, results showed that (1) BSEM-CL performed more closely to ESEM; (2) BSEM-CLRC did not provide more accurate model estimation compared with BSEM-CL; (3) BSEM-RC provided unstable estimation; and (4) different specifications of targeted values in ESEM and informative priors in BSEM have significant impacts on model estimation. The real data analysis (Study 2) showed that the differences in estimation between different models were largely consistent with those in Study1 but somewhat smaller.  相似文献

A large body of research in support of the reciprocal effects model of causal ordering demonstrates that prior academic self-concept predicts subsequent academic achievement beyond what can be explained in terms of prior achievement. Here we evaluate the generalizability of this support for the reciprocal effects model to a physical activity context in which achievement is reflected in gymnastics skills on a standardized gymnastics performance test evaluated by expert judges. Based on the responses of 376 adolescents collected at the start (T1) and end (T2) of a gymnastics training programme, there is support for a reciprocal effects model in which there are significant paths leading from both T1 gymnastics self-concept to T2 gymnastics skills and from T1 gymnastics skills to T2 self-concept. Although there were gender and age effects (girls and older participants had better gymnastics skills, boys had higher self-concepts), multiple group structural equation models indicated that support for the reciprocal effects model generalized over responses by boys and girls. In summary, self-concept and performance are both determinants and consequences of each other.  相似文献

In 2015 the government initiated reforms to GCSE English Literature which included a shift from open book to closed book examinations. This change, now being implemented in schools, has been overlooked in research and policy discourse. This study compares government intentions for the reforms with teachers’ experiences of teaching poetry, using data drawn from interviews with seven teachers. Teachers felt the demands of closed book examinations affected their autonomy, distribution of classroom time and students’ creative relationship with poetry. This study raises questions as to whether closed book examinations are appropriate for assessing poetry and are conducive to a fulfilling poetry education.  相似文献

This paper presents an analysis of three presidential candidates, George H. W. Bush, Bill Clinton, and Ross Perot, who participated in the 1992 presidential debates. The relationships among the three candidates and between each candidate and the issues were examined using semantic network analysis. The results indicate a two-against-one strategy that was issue specific. The candidates teamed up in different pairs, depending on the topic at hand. The results also show the issues that the candidates emphasized most. Specifically, Clinton and Perot had more focused communication consistent with their respective campaign themes of domestic and financial concerns, while Bush did not emphasize any one particular theme. The implications of these differences are discussed, as are the theoretical and practical implications for debater tactics and the strategic use of language for emphasizing political platforms.  相似文献
