- An important question for parents and educators alike is how to promote adolescents’ academic identity and school performance. This study investigated relations among parental education, parents’ attitudes toward their adolescents’ school, parental support for learning at home, and adolescents’ academic identity and school performance over time and in different national contexts. Longitudinal data were collected from adolescents and their parents in nine countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the United States). When adolescents were 16 years old, their mothers (N = 1083) and fathers (N = 859) provided data. When adolescents were 17 years old, 1049 adolescents (50% girls) and their mothers (N = 1001) and fathers (N = 749) provided data. Multiple-group path analyses indicated that, across cultures, higher parent education was associated with better adolescent school performance. Parents’ attitudes toward their adolescents’ school and parent support for learning in the home were not associated with adolescents’ school performance but were associated with academic identity. The findings suggest somewhat different pathways to school performance versus academic identity. Implications for helping parents and educators in different countries promote adolescents’ academic identity and achievement are discussed.

- Little is known about the developmental trajectories of parental self-efficacy as children transition into adolescence. This study examined parental self-efficacy among mothers and fathers over 3 1/2 years representing this transition, and whether the level and developmental trajectory of parental self-efficacy varied by cultural group. Data were drawn from three waves of the Parenting Across Cultures (PAC) project, a large-scale longitudinal, cross-cultural study, and included 1178 mothers and 1041 fathers of children who averaged 9.72 years of age at T1 (51.2% girls). Parents were from nine countries (12 ethnic/cultural groups), which were categorized into those with a predominant collectivistic (i.e., China, Kenya, Philippines, Thailand, Colombia, and Jordan) or individualistic (i.e., Italy, Sweden, and USA) cultural orientation based on Hofstede's Individualism Index (Hofstede Insights, 2021). Latent growth curve analyses supported the hypothesis that parental self-efficacy would decline as children transition into adolescence only for parents from more individualistic countries; parental self-efficacy increased over the same years among parents from more collectivistic countries. Secondary exploratory analyses showed that some demographic characteristics predicted the level and trajectory of parental self-efficacy differently for parents in more individualistic and more collectivistic countries. Results suggest that declines in parental self-efficacy documented in previous research are culturally influenced.

Tidskriftsartikel (refereegranskat)abstract
- In this study, we examine the predictions of a storm and stress characterization of adolescence concerning typicality and trajectories of internalizing, externalizing, and wellbeing from late childhood through late adolescence. Using data from the Parenting Across Cultures study, levels and trajectories of these characteristics were analyzed for 1,211 adolescents from 11 cultural groups across eight countries. Data were longitudinal, collected at seven timepoints from 8 to 17 years of age. Results provide more support for a storm and stress characterization with respect to the developmental trajectories of behavior and characteristics from childhood to adolescence or across the adolescent years than with respect to typicality of behavior. Overall, adolescents' behavior was more positive than negative in all cultural groups across childhood and adolescence. There was cultural variability in both prevalence and trajectories of behavior. The data provide support for arguments that a more positive and nuanced characterization of adolescence is appropriate and important.

- The global outbreak of COVID-19 has impacted all systems essential to human life and wellbeing (Masten & Motto-Stefanidi, 2020). The complex combination of health and economic stressors together with difficulty accessing protective factors may impact the family system in particular. Families differ in their responses to stressors (Bonanno et al., 2010), and the way in which families adjust to events and transitions related to the pandemic may be related to the distress perceived by children and their long-term wellbeing (Felix et al., 2013).This symposium will examine whether and through which processes families adjust during the global outbreak of COVID-19. We explore 2 research questions: 1)What did families do during the pandemic to maintain resilience? 2)What are the main protective and risk factors within the family context that are related to children’s and adolescents’ adjustment during this stressful and potentially traumatic event?Three strengths characterize the symposium. First, longitudinal designs with pre- and post-onset measurements enabled us to capture the dynamic nature of changes impacted by the COVID-19 outbreak. Second, the global nature of the outbreak is represented in cross-cultural perspective to understand commonalities and specificities of the processes activated by the event in different countries from Europe, North America, and Asia. Finally, mechanisms of resiliency and vulnerability examining the adjustment of the family members are assessed through longitudinal moderation and mediation analyses.

- INTRODUCTION: Creating romantic relationships characterized by high-quality, satisfaction, few conflicts, and reasoning strategies to handle conflicts is an important developmental task for adolescents connected to the relational models they receive from their parents. This study examines how parent-adolescent conflicts, attachment, positive parenting, and communication are related to adolescents' romantic relationship quality, satisfaction, conflicts, and management.METHOD: We interviewed 311 adolescents at two time points (females = 52%, ages 15 and 17) in eight countries (China, Colombia, Italy, Kenya, the Philippines, Sweden, Thailand, and the United States). Generalized and linear mixed models were run considering the participants' nesting within countries.RESULTS: Adolescents with negative conflicts with their parents reported low romantic relationship quality and satisfaction and high conflicts with their romantic partners. Adolescents experiencing an anxious attachment to their parents reported low romantic relationship quality, while adolescents with positive parenting showed high romantic relationship satisfaction. However, no association between parent-adolescent relationships and conflict management skills involving reasoning with the partner was found. No associations of parent-adolescent communication with romantic relationship dimensions emerged, nor was there any effect of the country on romantic relationship quality or satisfaction.CONCLUSION: These results stress the relevance of parent-adolescent conflicts and attachment as factors connected to how adolescents experience romantic relationships.

Failure Analysis of Multilayered Suspension Plasma-Sprayed Thermal Barrier Coatings for Gas Turbine Applications
- 2018
-

- 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.

- Sex-driven immune differences can affect tumor progression and the landscape of the tumor microenvironment. Deeper understanding of these differences in males and females can inform patient selection to improve sex-optimized immunotherapy treatments. In this study, single-cell RNA sequencing and protein analyses uncovered a subpopulation of myeloid cells in pancreatic lesions associated with an immune-excluded tumor phenotype and effector T-cell exhaustion exclusively in females. This myeloid subpopulation was positively correlated with poor survival and genetic signatures of M2-like macrophages and T-cell exhaustion in females. The G-protein coupled receptor formyl peptide receptor 2 (FPR2) mediated these immunosuppressive effects. In vitro, treatment of myeloid cells with a specific FPR2 antagonist prevented exhaustion and enhanced cytotoxicity of effector cells. Proteomic analysis revealed high expression of immunosuppressive secretory proteins PGE2 and galectin-9, enriched integrin pathway, and reduced proinflammatory signals like TNFα and IFNγ in female M2-like macrophages upon FPR2 agonist treatment. In addition, myeloid cells treated with FPR2 agonists induced TIM3 and PD-1 expression only in female T cells. Treatment with anti-TIM3 antibodies reversed T-cell exhaustion and stimulated their ability to infiltrate and kill pancreatic spheroids. In vivo, progression of syngeneic pancreatic tumors was significantly suppressed in FPR2 knockout (KO) female mice compared with wild-type (WT) female mice and to WT and FPR2 KO male mice. In female mice, inoculation of tumors with FPR2 KO macrophages significantly reduced tumor growth compared with WT macrophages. Overall, this study identified an immunosuppressive function of FPR2 in females, highlighting a potential sex-specific precision immunotherapy strategy.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- 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.
