Marginal Nested Interactions for Contingency Tables

We introduce a new definition of generalized marginal interactions, called marginal nested interactions, which includes baseline, local, continuation and reverse continuation logits and odds ratios as special cases. The significant aspect of this definition is the inclusion of new types of logits and odds ratios that can handle non-ordinal, ordinal and partially ordered categorical variables in a flexible and appropriate way. It is proved also that the marginal nested interactions define a saturated model of a multi-way contingency table.

重庆市经济发展与城乡统筹的动态关系研究

基于协整理论和向量自回归模型,利用重庆市1985-2006年的统计数据对其经济发展与城乡统筹的动态关系进行了实证分析.结果表明:重庆市经济发展与城乡统筹间存在着长期稳定的协整关系;短期内只存在重庆城乡统筹到经济发展的单向因果关系,但长期存在着一种双向的、互为因果的动态关系;同时,经济发展并不会自动促进城乡差距的缩小,若没有相关政策的调整,中长期内会继续加大城乡差距,而短期内城乡统筹对经济发展的影响并不明显,长期内在国家现有宏观政策的驱动下城乡统筹发展会促进经济发展.     

Interacting neighbour point processes: Some models for clustering

We introduce a class of spatial point processesinteracting neighbour point (INP) processes, where the density of the process can be written by means of local interactions between a point and subsets of its neighbourhood but where the processes may not be Ripley-Kelly Markov processes with respect to this neighbourhood. We show that the processes are iterated Markov processes defined by Hayat and Gubner (1996). Furthermore, we pay special attention to a subclass of interacting neighbour processes, where the density belongs to the exponential family and all neighbours of a point affect it simultaneously. A simulation study is presented to show that some simple processes of this subclass can produce clustered patterns of great variety. Finally, an empirical example is given.     

Person × Context Effects on Anticipated Moral Emotions Following Aggression

We investigated person (sex, aggression level), context (witness type, victim reactions), and person × context effects on children's anticipated moral emotions following hypothetical acts of aggression against a peer. Children (N = 378, mean age = 11.3 years) were presented a series of hypothetical vignettes in which the presence of witnesses (no witnesses/most liked classmates/all of the class) and victim's reactions (neutral/ sad/ angry) were manipulated. The results indicated several person effects (e.g., girls anticipated more guilt and shame but less pride than boys; aggressiveness was related to less guilt and shame), as well as context effects (e.g., anticipated shame depended on who witnessed the situation and the emotional reactions of the victim). However, person × context effects predominated. The overall pattern of results indicated that girls and low‐aggressive children were more sensitive to contextual cues than boys and high‐aggressive children. The findings support the importance of a person × context approach to understanding the emotional reactions of different children in different situations.     

Emotional Availability During Mother–Child Interactions in Divorcing and Intact Married Families

Low-quality parent–child interactions have been associated with children's behavioral and emotional problems. Further, research has shown that divorce can be a stressful time for both parents and children, and might be linked with children's negative adjustment. The hypothesis of this study was that parent–child dyads will show lower quality interactions in divorcing versus intact families. Specifically, we posited lower mean scores on emotional availability (EA), which includes four caregiver qualities and two child qualities, during mother–child interactions in divorcing as compared with intact married families. Secondary data analysis was conducted on these two groups drawn from two separate samples. The samples were comparable in terms of maternal education and child age. Nonparametric tests revealed that these groups differed significantly on one dimension of EA—maternal sensitivity—with mother–child dyads from married families displaying a higher level of sensitivity than mother–child dyads from divorcing families. This finding could prompt new research as well as an increased emphasis on parental support in divorce-related interventions and education about the meaning of maternal sensitivity and how it could be maintained during the divorce transition.     

Design,Utility, and History of the Colorado Adoption Project: Examples Involving Adjustment Interactions

This article describes the Colorado Adoption Project (CAP), a longitudinal study in behavioral development, and discusses how adoption studies may be used to assess genetic and environmental etiologies of individual differences for important developmental outcomes. Previous CAP research on adjustment outcomes in childhood and adolescence—which found significant interactions, including gene-environment interactions—is reviewed. New research suggests mediating effects of menarche and religiosity on age at first sex in this predominantly middle-class, Caucasian sample.

A revisit to two-way factorial ANOVA with mixed effects and interactions

Abstract

Two mixed models exist in analysis of two-way factorial ANOVA with mixed effects and interactions: the constrained and unconstrained models. The constrained model is unfavored because there is no convincing rationale for the enforced constraints on its random interactions and a lack of clear interpretation about its variance components. The purpose of this study is to further explore the relationship between these two models. We reveal some nice features of the constrained model on partition of the responsive variance. An alternative formulation of ANOVA that follows from this exploration is also presented.
