Statistical Power of the Multiple Domain Latent Growth Model for Detecting Group Differences

The latent growth model (LGM) in structural equation modeling (SEM) may be extended to allow for the modeling of associations among multiple latent growth trajectories, resulting in a multiple domain latent growth model (MDLGM). While the MDLGM is conceived as a more powerful multivariate analysis technique, the examination of its methodological performance is very limited. Hence, the present study compared the power of the MDLGM with that of a set of univariate LGMs for detecting group differences in growth rates over time using a Monte Carlo study with a two-group and two-domain design. The results indicated that there were different scenarios where the power rates for the MDLGM were greater than that of the set of LGMs (and vice versa) due to a joint function of the two domains’ intercorrelation size and the group difference effect size.     

“Montrose” child life protection unit: A treatment and assessment model in child abuse intervention

In New South Wales, Australia, the Department of Youth and Community Services is empowered by statute to deal with cases of child abuse and neglect. Its child protection services include the Montrose Child Life Protection Unit which is designed to support and complement the work of both the Intake Service, Field Service and most importantly the work of child protective facilities in the community. The service has intake crisis counselling and call out resources; maintains a central register; provides a facility for crisis residential care for children and families, diagnostic assessment, and a day programme. The emphasis in service delivery in New South Wales in the area of child protection is on multidisciplinary intervention. The Department of Youth and Community Services is involved in promoting interagency cooperation and co-ordination. Over and above a philosophy that underlies service delivery is the Montrose Unit's involvement in sensitising the community to the difficult and often demanding role of parenting. Montrose represents an attempt to create an environment where parenting myths can be examined from a reality base and strategies implemented for reeducation.     

带锈铸铁脱盐缓蚀后的耐蚀性能研究

在加入钼酸盐与硅酸盐复合缓蚀剂的碱性脱盐溶液中,对带锈铸铁进行脱盐缓蚀处理,对带锈铸铁处理前后的耐蚀性能进行了测试评价,并运用扫描电子显微镜和傅里叶变换红外光谱仪对锈层形貌结构进行了分析。结果表明,在该体系中脱盐缓蚀处理后,铸铁的腐蚀速度下降至5%以下,脱盐缓蚀改善了锈层结构,锈层主要组成由不稳定锈γ-FeOOH向稳定的α-FeOOH转变,锈层结合紧密,铸铁的耐蚀性能提高。
