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.     

小说社会学研究的理论范式及其转换空间

在20世纪文学批评领域内，小说社会学研究的理论模式与批评范式在历史与审美的交融中，逐步由“外在批评”转向与“内在研究”的结合。其中，戈德曼的“发生学结构主义”文学社会学理论、深入研究文本结构要素与特定社会精神结构三者间的复杂关系，生成了独特的批评视角。由此，运用“社会学的想像力”，将“发生学结构主义”文学研究方法在中国小说文本研究中加以转换，便可探讨社会学方法与其他方法结合的可能性，拓展小说社会学领域广阔的再生空间。

From climate change victims to climate change actors: The role of eco-parenting in building mitigation and adaptation capacities in children

Studies have acknowledged children not as climate change victims only, but also as climate change actors. However, only a few have addressed the preparatory stages of children as climate change actors. However, the few studies that addressed these preparatory stages gave attention only to the roles of schools and government agencies without adequate attention to that of parents. This article therefore attempts to discuss the role of eco-parenting in building mitigation and adaptation capacities in children. Relying on the authoritative parenting model, the article avers that eco-parenting can have significant effects on children's ability to protect the environment, mitigate, and adapt to climate change impacts.
