- Over the past 10 years, Oosterhof and Todorov's valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions. We addressed this question by replicating Oosterhof and Todorov's methodology across 11 world regions, 41 countries and 11,570 participants. When we used Oosterhof and Todorov's original analysis strategy, the valence-dominance model generalized across regions. When we used an alternative methodology to allow for correlated dimensions, we observed much less generalization. Collectively, these results suggest that, while the valence-dominance model generalizes very well across regions when dimensions are forced to be orthogonal, regional differences are revealed when we use different extraction methods and correlate and rotate the dimension reduction solution.

- Improvement in the performance of thermal barrier coatings (TBCs) is one of the key objectives for further development of gas turbine applications. The material most commonly used as TBC topcoat is yttria-stabilized zirconia (YSZ). However, the usage of YSZ is limited by the operating temperature range which in turn restricts the engine efficiency. Materials such as pyrochlores, perovskites, rare earth garnets are suitable candidates which could replace YSZ as they exhibit lower thermal conductivity and higher phase stability at elevated temperatures. The objective of this work was to investigate different multilayered TBCs consisting of advanced topcoat materials fabricated by suspension plasma spraying (SPS). The investigated topcoat materials were YSZ, dysprosia-stabilized zirconia, gadolinium zirconate, and ceria–yttria-stabilized zirconia. All topcoats were deposited by TriplexPro-210TM plasma spray gun and radial injection of suspension. Lifetime of these samples was examined by thermal cyclic fatigue and thermal shock testing. Microstructure analysis of as-sprayed and failed specimens was performed with scanning electron microscope. The failure mechanisms in each case have been discussed in this article. The results show that SPS could be a promising route to produce multilayered TBCs for high-temperature applications.

- Longitudinal data from the Parenting Across Cultures study of children, mothers, and fathers in 12 cultural groups in nine countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the USA; N = 1331 families) were used to understand predictors of compliance with COVID-19 mitigation strategies and vaccine hesitancy. Confidence in government responses to the COVID pandemic was also examined as a potential moderator of links between pre-COVID risk factors and compliance with COVID mitigation strategies and vaccine hesitancy. Greater confidence in government responses to the COVID pandemic was associated with greater compliance with COVID mitigation strategies and less vaccine hesitancy across cultures and reporters. Pre-COVID financial strain and family stress were less consistent predictors of compliance with COVID mitigation strategies and vaccine hesitancy than confidence in government responses to the pandemic. Findings suggest the importance of bolstering confidence in government responses to future human ecosystem disruptions, perhaps through consistent, clear, non-partisan messaging and transparency in acknowledging limitations and admitting mistakes to inspire compliance with government and public health recommendations. © 2022, Society for Prevention Research.

- Parent and child endorsement of reactive aggression both predict the emergence of child aggression, but they are rarely studied together and in longitudinal contexts. The present study does so by examining the unique predictive effects of parent and child endorsement of reactive aggression at age 8 on child aggression at age 9 in 1456 children from 13 cultural groups in 9 nations. Multiple group structural equation models explored whether age 8 child and parent endorsement of reactive aggression predicted subsequent age 9 child endorsement of reactive aggression and child aggression, after accounting for prior child aggression and parent education. Results revealed that greater parent endorsement of reactive aggression at age 8 predicted greater child endorsement of aggression at age 9, that greater parent endorsement of reactive aggression at age 8 uniquely predicted greater aggression at age 9 in girls, and that greater child endorsement of reactive aggression at age 8 uniquely predicted greater aggression at age 9 in boys. All three of these associations emerged across cultures. Implications of, and explanations for, study findings are discussed.

- The Family Stress Model of Economic Hardship (FSM) posits that economic situations create differences in psychosocial outcomes for parents and developmental outcomes for their adolescent children. However, prior studies guided by the FSM have been mostly in high-income countries and have included only mother report or have not disaggregated mother and father report. Our focal research questions were whether the indirect effect of economic hardship on adolescent mental health was mediated by economic pressure, parental depression, dysfunctional dyadic coping, and parenting, and whether these relations differed by culture and mother versus father report. We conducted multiple group serial mediation path models using longitudinal data from adolescents ages 12–15 in 2008–2012 from 1,082 families in 10 cultural groups in seven countries (Colombia, Italy, Jordan, Kenya, the Philippines, Thailand, and the United States). Taken together, the indirect effect findings suggest partial support for the FSM in most cultural groups across study countries. We found associations among economic hardship, parental depression, parenting, and adolescent internalizing and externalizing. Findings support polices and interventions aimed at disrupting each path in the model to mitigate the effects of economic hardship on parental depression, harsh parenting, and adolescents’ externalizing and internalizing problems. © 2022 Elsevier Ltd

Household income loss, parental depression, and adolescent internalizing/externalizing behavior : A longitudinal study in seven countries.
- 2021

Konferensbidrag (refereegranskat)abstract
- A large body of previous research using the family stress model has examined relations among economic pressure, parental psychological distress, and child psychosocial development. However, the impact of income loss changes in the broader macro-economic cultural context in which families are situated. For example, in countries with more generous social safety nets or where helping extended family members is more normative, income loss may be less predictive of parent and child psychosocial outcomes. This study examined the longitudinal links among the adverse event of severe household income loss, parental depression, and adolescent internalizing and externalizing behavior. Longitudinal data from 1,082 families in 10 cultural groups in seven countries (Colombia, Italy, Jordan, Kenya, Philippines, Thailand, and United States) were included. The data on income were collected between 2011 and 2013, a period when Italy was in recession and many of the other countries had just started recovering from a period or multiple periods of recession. Across all countries, when the child was 12 years old (referencing a 12 month period somewhere between 2011 and 2013), 14% of families had experienced a decrease in their household annual income by more than 25% (ranging from 4% of families in Colombia to 25% of families in Naples, Italy). A multiple-group structural equation model was conducted with 5,000 bootstrap replications. We constrained all paths to be equal across cultures and then used an iterative process of referencing modification indices to indicate whether to release a path in a specific culture. We then used chi square difference tests to assess whether the restricted model with equal paths was significantly worse than the alternative model allowing a loading to differ in one culture. The final model released an average of 4.5 paths per culture (out of a possible 27) and fit the data well (RMSEA=.040 90% CI: .016, .056; CFI/TLI=.971/.962; SRMR=.073) revealed that controlling for child gender, parental education, household income, former severe income loss, and age 12 internalizing and externalizing behavior, maternal depression (age 13) fully mediated the relation between a family experiencing severe income loss (age 12) and child internalizing behavior (age 14) in all cultures except the Philippines. However, paternal depression did not mediate this relation. There was no significant relation with any of the variables and child externalizing in any of the cultural groups. Additionally, we found in Thailand, household income (standardized within cultural group) moderated the relation between severe income loss and both maternal and paternal depression. This study largely found effects of severe income loss on maternal depression and child internalizing, regardless of the level of income before the loss, indicating that although those living in poverty may be the most vulnerable to adverse effects on child development, in 9 out of 10 cultures in the study, the effects of severe income loss on family stress did not vary as a function of household income. This finding supports policies such as Universal Basic Income and cash transfers, to potentially mitigate the effects severe income loss.

Tidskriftsartikel (refereegranskat)abstract
- Introduction We sought to understand the relation between positive parenting and adolescent diet, whether adolescents’ internalizing and externalizing behaviors mediate relations between positive parenting and adolescent diet, and whether the same associations hold for both boys and girls and across cultural groups. Methods Adolescents (N = 1334) in 12 cultural groups in nine countries were followed longitudinally from age 12 to 15. We estimated two sets of multiple group structural equation models, one by gender and one by cultural group. Results Modeling by gender, our findings suggest a direct effect of positive parenting at age 12 on a higher quality diet at age 15 for males (beta = .140; 95% CI: 0.057, 0.229), but an indirect effect of positive parenting at age 12 on a higher quality diet at age 15 by decreasing externalizing behaviors at age 14 for females (beta = .011; 95% CI: 0.002, 0.029). Modeling by cultural group, we found no significant direct effect of positive parenting at age 12 on the quality of adolescent diet at age 15. There was a significant negative effect of positive parenting at age 12 on internalizing (beta = -.065; 95% CI: -0.119, -0.009) and externalizing at age 14 (beta = -.033; 95% CI: -0.086, -0.018). Conclusions We founder gender differences in the relations among positive parenting, adolescents’ externalizing and internalizing behaviors, and adolescent diet. Our findings indicate that quality of parenting is important not only in promoting adolescent mental health but potentially also in promoting the quality of adolescents’ diet.
