Adolescent Attachment Trajectories With Mothers and Fathers: The Importance of Parent–Child Relationship Experiences and Gender 下载免费PDF全文
This longitudinal study investigated how attachment with mothers and fathers changes during adolescence, and how gender and parent–child relationship experiences are associated with attachment trajectories. The relative importance of specific positive and negative relationship experiences on attachment trajectories was also examined. An initial sample of 223 adolescents reported on relationship experiences and attachment avoidance and anxiety with mothers and fathers in Grades 6, 8, 10, and 12 (final N = 110; Mage = 11.90 years at onset, SD = .43). Mothers and fathers reported on relationship experiences with adolescents. Hierarchical linear modeling showed that security with parents increased during adolescence. Positive relationship experiences (companionship, satisfaction, approval, support) predicted increases in security, and negative experiences (pressure, criticism) predicted decreases in security. Females reported less avoidance than males. 相似文献

An assumption of multivariate normality for a decision model is validated in this paper. Measurements for the independent variables of a bond rating model were taken from a sample of municipal bonds. Three methods for examining both univariate and multivariate normality (including normal probability plots) are described and applied to the bond data. The results imply, after applying normalizing transformations to four of the variables, that the data reasonably approximate multivariate normality, thereby validating a distributional requirement of the discriminant-analysis-based decision model. The methods described in the paper may also be used by others interested in examining multivariate normality assumptions of decision models. 相似文献

The relationships of specific distinctive competencies to performance were examined for firm size, type of production system, and level of perceived environmental uncertainty (PEU). The size and dominant production system used by a firm were found to have main moderating effects on those relationships although PEU by itself did not. However, PEU did interact with size and production system to moderate those relationships. 相似文献
