Infant Distress and Regulatory Behaviors Vary as a Function of Attachment Security Regardless of Emotion Context and Maternal Involvement

Differences in infant distress and regulatory behaviors based on the quality of attachment to mother, emotion context (frustration versus fear), and whether or not mothers were actively involved in the emotion-eliciting tasks were examined in a sample of 98 16-month-old infants and their mothers. Dyads participated in the Strange Situation, a limiting task designed to elicit infant frustration, and a novelty task designed to elicit infant fear. Mothers were asked to remain uninvolved during the first minute of each task, and then instructed to engage with their infants as they wished for the remaining three minutes. Independent of concurrent maternal sensitivity, resistant infants were significantly more distressed than secure and avoidant infants. Avoidant infants engaged in fewer active mother-oriented regulation behaviors than secure and resistant infants and engaged in more self-soothing in the mother involved condition than the mother uninvolved condition. Resistant infants engaged in more physical comfort with their mothers and more venting than both secure and avoidant infants, and exhibited a smaller variety of adaptive non-mother-oriented strategies than did secure infants. There were few differences in infant distress and regulatory behaviors as a function of emotion task and maternal involvement. Limitations and implications for future research are discussed.     

Child Benefit Portfolios Across OECD Countries

Current research on the cross-national pattern of investment in child benefits mostly adopts the total resources approach and the model family method. The total resources approach conducts a broad comparison of the aggregate expenditure of different types of child benefit across countries. The model family method adds sophistication by comparing the values of child benefit packages of different countries, which combines different levels of spending in each type of child benefit, based on different family types with certain assumed characteristics. To complement the existing approaches, this study uses cluster analysis to classify countries into groups of similar investment strategies by simultaneously counting the different types and levels of child benefits of all countries. The findings show that four types of child benefit investment portfolio, namely Active, Moderate, Conservative, and Minimal, can be identified across OECD countries. While some studies have focused on the effects of individual types of child benefit on child outcomes, little is known about the effects of child benefits as a whole. The pattern of child benefits as investment portfolios could serve as a basis facilitating further investigation into its relationship with child outcomes. Preliminary findings indicate that child poverty, health, and satisfaction with school life differ significantly across investment portfolios, especially Active Investment outperforms Minimal Investment consistently.     

‘My Parents told us that they will always Treat my Brother Differently Because he is Autistic’ – Are Siblings of Autistic Children the Forgotten Ones?

Autism spectrum disorder (ASD) does not only affect the child alone, but the family unit as well. This qualitative study explored the impacts of ASD on the relationship between parents and their neuro-typical children and how the neuro-typical children cope with the impacts of having an autistic sibling in the family. Utilising principles of the social relations theory, five Singaporean families (n = 10) consisting of five mothers and five neuro-typical children were interviewed. Both the mothers and the neuro-typical children were seen to be equal agents in influencing the interactions with each other, and contributed in maintaining the close relationship through various strategies. Findings revealed that having an autistic child in the family imposed certain constraints and additional responsibilities for the family members. Despite so, the neuro-typical children coped well with such constraints. The in-depth data highlight the value of considering both the agency of mothers and the neuro-typical children and how they bidirectionally influence each other while sharing the caregiving roles for the autistic child in the family. It is strongly recommended for practitioners to incorporate elements of child's agency when expanding their scope of psychosocial intervention work with the neuro-typical children.     

Robust bootstrap forecast densities for GARCH returns and volatilities

Bootstrap procedures are useful to obtain forecast densities for both returns and volatilities in the context of generalized autoregressive conditional heteroscedasticity models. In this paper, we analyse the effect of additive outliers on the finite sample properties of these bootstrap densities and show that, when obtained using maximum likelihood estimates of the parameters and standard filters for the volatilities, they are badly affected with dramatic consequences on the estimation of Value-at-Risk. We propose constructing bootstrap densities for returns and volatilities using a robust parameter estimator based on variance targeting implemented together with an adequate modification of the volatility filter. We show that the performance of the proposed procedure is adequate when compared with available robust alternatives. The results are illustrated with both simulated and real data.     

The complementarity of internal integration and product modularity: An empirical study of their interaction effect on competitive capabilities

Modular product design and internal integration are commonly adopted by manufacturers to improve operational performance. A number of studies argue that the adoption of product modularity significantly alters organization design, which affects the impact of internal integration on competitive capabilities. This paper thus aims to empirically explore the individual effects as well as interaction effects of product modularity and internal integration on competitive capabilities. The competitive capabilities studied in this paper include product innovativeness, low price, product quality, delivery, flexibility and customer services. After analysing the data from 251 Hong Kong manufacturers through moderated multiple regression analysis, the study found that better internal integration can significantly improve product innovativeness, product quality, delivery, flexibility and customer services, while a high level of product modularity enhances product innovativeness, flexibility and customer services. More importantly, the study shows that internal integration and product modularity can interact to improve product innovativeness and product quality. These results enhance our understanding of the interaction of product design and organizational coordination.     

Rational-experiential thinking style and rational intergroup cooperation: the moderating role of intergroup conflict / Estilos de pensamiento racional-experiencial y la cooperación intergrupal racional: el rol modulador del conflicto intergrupal

Cooperative relationships between groups are difficult because of the high human capability to differentiate between in-group vs. out-group members. This obstacle exists even when the groups can obtain benefits for themselves from cooperation with other groups (rational cooperation). Based on an interactionist approach, the authors propose that personal (individual differences) and situational (conflicts) factors contribute to rational intergroup cooperation. The authors conducted a preliminary correlational study (Study 1) and an experimental investigation (Study 2). In Study 1, the authors examined, with 105 participants, the psychometric properties of the Spanish version of the Rational–Experiential Inventory (REI), measuring individual differences in information processing. In Study 2, the authors conducted an experimental investigation with 141 participants, testing the role of individual differences and conflict in intergroup rational cooperation. Findings of Study 1 showed that the scale has adequate psychometric properties. Results of Study 2 confirmed that the existence of both manipulated and perceived intergroup conflict reduces the magnitudes of the relationships between rational ability and rational cooperation. In addition, perceived intergroup conflict increased the magnitude of the links from experiential ability and experimental engagement to rational cooperation. Both individual differences and previous conflict have a role in predicting rational intergroup cooperation. According to the interactionist approach, personal and situational factors should be considered in the understanding of intergroup relationships.     

European‐American and African‐American Mothers' Emotion Socialization Practices Relate Differently to Their Children's Academic and Social‐emotional Competence

The current study examines whether the relation between mothers' responses to their children's negative emotions and teachers' reports of children's academic performance and social‐emotional competence are similar or different for European‐American and African‐American families. Two hundred mothers (137 European‐American, 63 African‐American) reported on their responses to their five‐year‐old children's negative emotions and 150 kindergarten teachers reported on these children's current academic standing and skillfulness with peers. Problem‐focused responses to children's negative emotions, which have traditionally been considered a supportive response, were positively associated with children's school competence for European‐American children, but expressive encouragement, another response considered supportive, was negatively associated with children's competence for African‐American children. The findings highlight the need to examine parental socialization practices from a culturally specific lens.     

Differentiating Processes of Control and Understanding in the Early Development of Emotion and Cognition

In this study, we examined the hypothesis that preschoolers' performance on emotion and cognitive tasks is organized into discrete processes of control and understanding within the domains of emotion and cognition. Additionally, we examined the relations among component processes using mother report, behavioral observation, and physiological measures of emotion control. Participants were 263 children (42 percent non‐White) and their mothers. Results indicated that the three approaches of measuring emotion control were unrelated. Regardless of the measurement method, a four‐factor solution differentiating emotion control and understanding and cognitive control and understanding fits the data better than did either of two two‐factor models, one based on domains of emotion and cognition across processes, and one based on processes of control and understanding across domains. Results of this research replicate those of Leerkes et al. in describing a differentiated underlying structure of emotion and cognition processes in early childhood while also extending these conclusions across samples and across measurement approaches for assessing emotion control.     

Spatially varying dynamic coefficient models

In this work we present a flexible class of linear models to treat observations made in discrete time and continuous space, where the regression coefficients vary smoothly in time and space. This kind of model is particularly appealing in situations where the effect of one or more explanatory processes on the response present substantial heterogeneity in both dimensions. We describe how to perform inference for this class of models and also how to perform forecasting in time and interpolation in space, using simulation techniques. The performance of the algorithm to estimate the parameters of the model and to perform prediction in time is investigated with simulated data sets. The proposed methodology is used to model pollution levels in the Northeast of the United States.
