RESUMEN
BACKGROUND: Social media is one of the major platforms for disseminating essential health messages. The present study examined the effect of message framing (self-interest motive, prosocial motive) on an online platform for parental intention to vaccinate against COVID-19. It also examined how the effect may vary across participants' levels of parental identity centrality/salience and community orientation before the vaccine was officially available. METHODS: Six hundred and sixty-three Hong Kong Chinese parents were recruited, and a total of 278 valid responses were retained in the analyses. Participants were randomly assigned to one of the three conditions: self-interest motive, prosocial motive, and control. Participants in the self-interest motive condition and the prosocial motive condition read a condition-specific message about the COVID-19 vaccine. Then, they reported their levels of intention to vaccinate against COVID-19, including parent-vaccination, child-vaccination, and medical information-seeking. RESULTS: A significant group effect on child-vaccination was found. Participants in the self-interest motive condition reported a higher intention to vaccinate their children against COVID-19 compared with the other two conditions. Results of moderation analyses indicated that communal orientation moderated the effect of a self-interest-motive-emphasized message on parental intention to vaccinate against COVID-19. The effect of a self-interest-motive-emphasized message appeared to be stronger on parent-vaccination, child-vaccination, and medical information-seeking among parents who reported lower levels of communal orientation. CONCLUSION: These findings provided some initial evidence of the effectiveness of message-framing in promoting parents' intention to vaccinate their children on online platforms.
RESUMEN
Personal growth and self-expressive goals have become increasingly important in modern marriages. In dual-earner couples, sharing work-related experiences with the partner can be particularly important in promoting mutual support for each other's personal growth. The current study examined dual-earner couples' sharing of work-related experiences and how it influenced both partners' relationship satisfaction and personal well-being. A total of 102 heterosexual dual-earner couples were recruited from communities in Hong Kong. They completed a pretest survey, a 14-day daily diary study, and a follow-up survey 1 year later. The Actor-Partner Interdependence Model was adopted to analyze the dyadic effects of sharing positive and negative work-related experiences on relationship satisfaction and personal well-being on the same day and 1 year later. In general, the sharing of both positive and negative work-related experiences had beneficial effects on the outcomes. Specifically, wives' sharing had more immediate effects on both partners' relational and personal well-being, whereas husbands' sharing had more long-term effects on the partner's personal well-being. The findings highlight the importance of work-related sharing in dual-earner couples. Practical implications are discussed.
RESUMEN
Background: Sepsis, a severe infectious disease, carries a high mortality rate. Early detection and prompt treatment are crucial for reducing mortality and improving prognosis. The aim of this research is to develop a clinical prediction model using machine learning algorithms, leveraging complete blood cell (CBC) parameters, to detect sepsis at an early stage. Methods: The study involved 572 patients admitted to West China Hospital of Sichuan University between July 2020 and September 2021. Among them, 215 were diagnosed with sepsis, while 357 had local infections. Demographic information was collected, and 57 CBC parameters were analyzed to identify potential predictors using techniques such as the Least Absolute Shrinkage and Selection Operator (LASSO), Random Forest (RF), Support Vector Machine (SVM), and eXtreme Gradient Boosting (XGBoost). The prediction model was built using Logistic Regression and evaluated for diagnostic specificity, discrimination, and clinical applicability including metrics such as the area under the curve (AUC), calibration curve, clinical impact curve, and clinical decision curve. Additionally, the model's diagnostic performance was assessed on a separate validation cohort. Shapley's additive explanations (SHAP), and breakdown (BD) profiles were used to explain the contribution of each variable in predicting the outcome. Results: Among all the machine learning methods' prediction models, the LASSO-based model (λ = min) demonstrated the highest diagnostic performance in both the discovery cohort (AUC = 0.9446, P < 0.001) and the validation cohort (AUC = 0.9001, P < 0.001). Furthermore, upon local analysis and interpretation of the model, we demonstrated that LY-Z, MO-Z, and PLT-I had the most significant impact on the outcome. Conclusions: The predictive model based on CBC parameters can be utilized as an effective approach for the early detection of sepsis.
RESUMEN
BACKGROUND: Parents are often involved in their child's homework with the goal of improving their child's academic achievement. However, mixed findings were observed for the role of parental involvement in homework in shaping students' learning outcomes. AIMS: The present study examined whether and how the effect of parental involvement in homework on students' performance in science and math varies across sociocultural contexts by considering the degrees of societal collectivism-individualism. METHODS: The present study used a large-scale dataset, consisting of participants from 43 countries/regions, to test whether societal collectivism-individualism would moderate the relationship between three types of parental involvement (asking, helping and checking) in homework and elementary school students' academic performance in math and science. RESULTS: The multi-level analyses revealed diverse effects of different parental involvement behaviours for homework. Helping and checking behaviours were generally negatively associated with elementary school students' academic achievement, but asking behaviours were positively associated with their academic achievement. Importantly, the positive effect of asking behaviours was stronger, while the negative effect of helping behaviours was weaker in collectivistic societies than in individualistic societies. CONCLUSIONS: The present study highlights the importance of considering the multifaceted nature of parental homework involvement and the sociocultural contexts that vary in collectivism-individualism when evaluating the role of parents in elementary school students' learning in math and science.

Egoistic value is conceptualized as anti-environmental in many environmental value theories, yet contradictory evidence exists for its relation with pro-environmental attitude and behaviour. To provide insights into these inconsistent findings, this research examined the moderating role of the psychological distance of environmental problems on their relationship. Across one cross-sectional survey study (1008 community participants from the United States) and one World Values Survey study (66,704 nationally representative participants from 46 countries/regions), results converged in showing that psychological distance of environmental problems (i.e. climate change and local pollution) moderated the relationship between egoistic value and pro-environmental attitude and behaviour. Their association became more positive as that psychological distance got closer. Different patterns were observed for altruistic and biospheric values. These findings highlight the potential pro-environmental utility of egoistic value and the importance of paying attention to contexts when theorizing its relation with pro-environmental attitude and behaviour.
RESUMEN
This study aimed to investigate the longitudinal association between theory of mind (ToM) and loneliness as well as the potential moderating effects of parenting style on this association. A total of 689 Chinese third-grade students (341 girls and 348 boys; Mage = 9.23 years, SD = 0.66) were recruited from eight primary schools and were followed from Grade 3 to Grade 5. These students reported their primary caregivers' parenting style in third grade and completed the same ToM task and loneliness questionnaire at each time point from Grade 3 to Grade 5. The study's results indicated a bidirectional relationship between ToM and loneliness, implying that children with less developed ToM abilities tend to feel lonelier and, conversely, that higher levels of loneliness are associated with lower ToM skills. Moreover, the study demonstrated that parenting style influenced the association between ToM and loneliness. Specifically, the impact of ToM at Grade 3 on reducing loneliness at Grade 4 was greater among children who experienced high levels of rejection from their caregivers compared with those with low levels of rejection. In addition, this study found that loneliness at Grade 3 had a greater influence on ToM at Grade 5 for children experiencing low levels of emotional warmth from their caregivers than for those who experienced high levels of emotional warmth. These findings highlight the significance of ToM as both a precursor and consequence of children's loneliness and emphasize the variation in these longitudinal relationships based on the parenting styles of primary caregivers.

BACKGROUNDS: The immunomodulatory properties of human chorionic gonadotrophin (hCG) have been identified to be critical for successful pregnancy. However, the effects of hCG on peripheral γδT cells during early pregnancy have not been reported previously. METHODS: We cocultured the purified γδT cells and peripheral blood mononuclear cells (PBMCs) with early pregnancy-relevant hCG concentrations and investigated the changes in the immune functional characteristics of γδT cells via flow cytometry assays. RESULTS: The ratios of CD69+ and IL-10+ γδT cells were increased in early pregnant women compared to nonpregnant women. γδT cells expressed low levels of the mannose receptor (CD206) instead of the classical hCG/LH receptor for hCG. The direct treatment of purified γδT cells with early pregnancy-relevant hCG concentrations may have no significant effects on their immune functions. Interestingly, when PBMCs were treated with the same broad range of hCG concentrations, the ratios of CD69+ and IL-10+ γδT cells to total γδT cells were significantly increased. CONCLUSION: Certain early pregnancy-relevant hCG concentrations could enhance the ratios of peripheral CD69+ and IL-10+ γδT cells, contributing to the activation of γδT cells and immunological tolerance during early pregnancy. However, these affects may not be strongly mediated by direct ligand-receptor interactions and they may highly depend on immune microenvironment. Our novel observations propose a perspective into the endocrine-immune dialog that exists between the fetus and maternal immune cells.
