RESUMO

While a compassionate face for Germans mirrors others' suffering, for U.S. Americans, a compassionate face is one that expresses a slight smile, partly because U.S. Americans want to avoid feeling negative ("avoided negative affect"; ANA) more than do Germans. The present work examines what people in a non-WEIRD (i.e. Chinese) cultural context think a compassionate face looks like. Additionally, it investigates whether an individually-measured cultural variable (i.e. ANA) can explain differences in conceptualisations of compassion between Chinese and U.S. Americans. Participants in China and the U.S. selected the face that most resembles a compassionate face in a reverse correlation task and completed a measure of ANA. As predicted, Chinese mental representations of a compassionate face included more sadness and less happiness compared to U.S. American mental representations of a compassionate face, and Chinese participants wanted to avoid feeling negative less than did U.S. Americans. Finally, ANA mediated the cultural differences in conceptualisations of compassion. We discuss how ANA and conceptualisations of compassion might be related to how people view the experience versus the expression of different emotions. This work has important implications for therapeutic settings and the meaning of compassion in an increasingly globalised and connected world.

RESUMO

The reciprocity and variation of values and beliefs are dynamic features of the parent-child relationship. Parents and adolescents may hold congruent or incongruent views regarding the malleability of socioeconomic status (mindset of SES), potentially influencing adolescents' psychological and physiological stress outcomes, as reflected in stress perceptions and the hypothalamic-pituitary-adrenal (HPA) axis functioning. The current study investigated how patterns of parent-adolescent congruence and incongruence in mindset of SES were associated with adolescents' perceived stress and diurnal cortisol patterns four months later. A total of 253 adolescents (Mage = 12.60, 46.2% girls) and their parents (Mage = 40.09 years, 59.5% mothers) participated in this study. Polynomial regression analyses and response surface analyses showed that adolescents perceived lower levels of stress when they themselves or their parents reported a stronger growth mindset of SES. Additionally, adolescents with a stronger growth mindset of SES also exhibited a steeper diurnal cortisol slope. Moreover, parents' mindset significantly interacted with adolescents' mindset to influence adolescents' diurnal cortisol patterns such that when adolescents hold weaker growth mindset of SES, those with higher parental growth mindsets had significantly higher cortisol awakening response and steeper diurnal cortisol slope. Furthermore, adolescents who showed incongruence with their parents but had averagely stronger growth mindsets of SES reported a significantly steeper diurnal cortisol slope than those who had averagely weaker growth mindsets with their parents. The findings point to the beneficial impacts of the growth mindset of SES on stress-related outcomes among adolescents, as well as the significance of considering both parents' and adolescents' mindsets when exploring these associations.

RESUMO

Parental bonding is a strong determinant of children's health. One of the proposed pathways through which parenting impacts children's health is by altering the functioning of stress response systems. The current study aims to investigate the associations between two types of parental bonding (care and overprotection) and functioning of hypothalamic-pituitary-adrenal (HPA) axis (i.e., diurnal cortisol secretion) in a sample of 255 healthy adolescents (46.3% girls; aged 11-14 years). Participants completed the Parental Bonding Instrument and provided eight cortisol samples across two consecutive days to assess patterns of diurnal cortisol secretion. Multilevel modeling and multiple linear regression were utilized to test the main effects and interactive effects of parental care and overprotection on adolescents' wakeup cortisol, cortisol awakening response, cortisol slope, and total cortisol secretion. Results showed that parental care was associated with higher cortisol levels at awakening, while parental overprotection was associated with lower cortisol levels at awakening. Parental overprotection, but not parental care, was associated with flatter cortisol slopes. No interactive effects between parental care and overprotection on cortisol parameters emerged. The current findings add to the existing literature on parenting behavior and HPA functioning by showing that parental care and overprotection differently regulated daily cortisol parameters implicated in health.

RESUMO

The present study explored the trajectories of depressive symptoms over 12 years spanning from childhood to emerging adulthood and the between-trajectory differences in psychosocial adjustment among Chinese children (N = 492, 52.8% boys, aged 6 to 18 years at baseline) affected by parental HIV. Rebounding (12.6%), resilient (64.8%), and improving  (22.6%) trajectories were identified. Individuals in the rebounding trajectory reported the highest levels of psychological distress and the lowest levels of subjective well-being, positive self-regard, and personal strengths in adulthood. Individuals in the resilient trajectory reported lower levels of psychological distress and negative affect than those in the improving trajectory. The findings support the development of programs by policymakers and practitioners to improve the psychosocial adjustment of children who have been affected by parental HIV while considering individual differences in the trajectories of depressive symptoms.

RESUMO

OBJECTIVE: This research investigates how economic inequality shapes basic human values across three cross-national, cross-regional, and longitudinal studies (Ntotal  = 219,697). METHODS: Study 1 examined the relationship between objective economic inequality and values across 77 societies from all five continents (n = 170,525). Study 2 examined the relationship between objective economic inequality and values across 51 regions in the United States (n = 48,559). Study 3 used a two-year longitudinal design to examine the relationship between perceived economic inequality and values (n = 613). RESULTS: Results from multilevel modeling and longitudinal analysis suggested that people who lived in areas with higher economic inequality and who perceived higher economic inequality were more likely to endorse achievement and power values. Moreover, people who perceived higher economic inequality were less likely to endorse benevolence values. These effects were robust in within-country tests (Studies 2 and 3) but not in the cross-country tests (Study 1) when accounting for sociodemographic characteristics. CONCLUSIONS: Our findings suggest that economic inequality may act as an antecedent of self-enhancement values, particularly within countries. In a world of rising economic inequality, this may over time lead to an overemphasis on achievement and power which have been shown to erode social cohesion.

RESUMO

Purpose: Two studies were conducted to explore the patterns of positive affect (PA) and negative affect (NA) while considering collectivist cultural specificity (dialecticism) and to examine the associations of affective profiles with psychosocial adjustment. Methods: We used two Chinese samples, one comprising adults with adverse childhood experiences (N = 488) and one comprising ordinary adolescents (N = 635). The participants completed scales on PA, NA, and psychosocial adjustment, including mental health problems (depressive symptoms, anxiety), personal strengths (self-esteem, gratitude, resilience), and life satisfaction. Results: Three profiles were identified through latent profile analysis: well-adjusted (high PA, low NA), low affective (low PA, low NA), and moderate affective (moderate PA, moderate NA). Participants in the well-adjusted profile had the fewest mental health problems (depressive symptoms, anxiety) and scored highest on personal strengths (self-esteem, gratitude, resilience) and life satisfaction. Participants in the low affective profile had fewer mental health problems than those in the moderate affective profile. Conclusion: Individual differences and cultural variations should be considered when exploring affective profiles. Future interventions aimed at promoting affective well-being should accommodate dialecticism and individual differences in the target population.

RESUMO

OBJECTIVE: Subjective socioeconomic status (SES) is a well-established psychosocial determinant of adolescents' self-report health. However, whether low subjective SES is associated with stress-related physiological risks (e.g., dysregulations in the hypothalamic-pituitary-adrenal axis activity) remains uncertain. This study examined the impact of subjective SES with different reference groups (i.e., perception of family SES relative to other students in the school versus other people in the city) on adolescents' diurnal cortisol profiles. METHODS: A sample of 255 adolescents (aged 11-14 years; 53.7% boys) completed a battery of psychological scales, including school-referenced subjective SES and city-referenced subjective SES. Diurnal cortisol was assessed by collecting saliva samples four times a day across two consecutive days. Four cortisol parameters (cortisol at awakening, cortisol awakening response [CAR], cortisol slope, and total cortisol secretion [area under the curve with respect to ground {AUCg}]) were derived. RESULTS: Higher levels of school-referenced subjective SES were associated with higher cortisol levels at awakening (ß = 0.0483, standard error [SE] = 0.0219, p = .028), steeper cortisol slopes (ß = -0.0036, SE = 0.0017, p = .034), and higher cortisol AUCg (b = 0.50, SE = 0.24, p = .036), but not with CAR (p = .77), after adjusting for covariates. In contrast, city-referenced subjective SES was not associated with any of the cortisol parameters (cortisol at awakening [p = .90], CAR [p = .74], cortisol slope [p = .84], and cortisol AUCg [p = .68]). CONCLUSIONS: Our findings highlight the importance of the reference group for subjective SES and provide a further understanding of socioeconomic disparities in adolescents' stress physiology.

RESUMO

Perceptions of social mobility vary across countries. However, past studies have mostly focused on populations in Western developed countries. Little is known about perceptions of social mobility in non-Western developing countries. The current paper focuses on Chinese perceptions of social mobility using a large-scale nationally representative sample. We found that, overall, Chinese believed in upward social mobility. Moreover, different patterns of perceptions of social mobility were identified, which suggest that respondents experienced either upward or downward social mobility in the past, but all of them thought that they can move up in the future. Perceptions of social mobility were also linked to important sociodemographic and economic factors. We discuss these findings in relation to the Chinese economic context.

RESUMO

ABSTRACT Several studies have highlighted that facilitators' attitudes toward interventions are crucial for implementing innovative psychosocial interventions. However, in the emerging implementation science field, little research has examined how organizational and individual factors may influence teachers' positive attitudes and readiness toward evidence-based interventions. The current study investigated the association between teachers' quality of work life and their attitudes toward an innovative psychosocial intervention for children affected by parental HIV/AIDS; the study also probed the potential indirect roles of self-efficacy and burnout. A total of 157 teachers with different levels of involvement in the intervention study were recruited from 47 schools. Our results revealed that teachers' quality of work life was positively associated with their attitudes toward the intervention directly and indirectly through enhanced self-efficacy and reduced burnout. The findings highlight the importance of organizational and individual factors in successfully implementing innovative psychosocial interventions for vulnerable children in organizations such as schools. Researchers should work with organizations to provide the necessary quality of work life and sufficient training to semi-professionals in order to boost their self-efficacy, reduce their burnout, and improve their attitudes toward innovative intervention programs to achieve the expected effectiveness of the interventions, particularly in resource-limited regions.

RESUMO

This study aims to examine the mechanisms of how experiences of stigma affect suicidal behaviors through depression and substance use among migrant workers in China. A sample of 641 young rural-to-urban migrants was recruited in Beijing, China. Participants were assessed on their sociodemographic characteristics, suicidal behaviors, experiences of stigma, depression, and substance use. Path analysis was used to examine the relationship between experiences of stigma and suicidal behaviors as well as the mechanistic roles of depression and substance use. The path model showed a good model fit. While the direct path from experiences of stigma to suicidal behaviors was not significant, the indirect paths between these two concepts were significant. Experiences of stigma were positively associated with both depression and substance use, which in turn were positively related to suicidal behaviors. The chain effect from experiences of stigma, depression, substance use to suicidal behaviors was also significant. To prevent and reduce suicidal behaviors among migrant workers, targeted interventions focusing on reducing experiences of stigma and improving mental and behavioral health are needed.

RESUMO

BACKGROUND: Detection of ceftazidime/avibactam (CAZ/AVI) antibacterial activity is absolutely vital with the rapid growth of carbapenem resistant Enterobacteriaceae (CRE). But now, there is no available automated antimicrobial susceptibility testing card for CAZ/AVI, so Kirby-Bauer has become an economical and practical method for detecting CAZ/AVI antibacterial activity against Enterobacteriaceae. RESULT: In this study, antimicrobial susceptibility testing of CAZ/AVI against 386 Enterobacteriaceae (188 Klebsiella pneumoniae, 122 Escherichia coli, 76 Enterobacter cloacae) isolated from clinical patients was performed by broth microdilution. Of the 386 strains, 54 extended spectrum ß lactamases negative (ESBL(-)), 104 extended spectrum ß lactamases positive (ESBL(+)), 228 CRE. 287 isolates were susceptible to CAZ/AVI and 99 isolates were resistant to CAZ/AVI. At the same time, to obtain optimal content avibactam (AVI) disk containing ceftazidime (30 µg), inhibition zone diameter of four kinds of ceftazidime (30 µg) disk containing different AVI content (0 µg, 10 µg, 25 µg, 50 µg) were tested by Kirby-Bauer method. The microdilution broth method interpretation was used as the standard to estimate susceptible or resistance and then coherence analysis was carried out between Kirby-Bauer and broth microdilution. The result shows the inhibition zone diameter of 30 µg/50 µg disk, susceptible isolates: 20.5 mm-31.5 mm, resistance isolates: 8.25 mm-21.5 mm. The inhibition zone diameter of 30 µg/25 µg disk, susceptible isolates: 19.7 mm-31.3 mm, resistance isolates: 6.5 mm-19.2 mm. The inhibition zone diameter of 30 µg/10 µg disk, susceptible isolates: 19.5 mm-31 mm, resistance isolates: 6.5 mm-11 mm. The inhibition zone diameter of ceftazidime (30 µg), susceptible isolates: 6.5 mm-27.5 mm, resistance isolates 6.5 mm. CONCLUSION: Our results show that 30 µg/50 µg, 30 µg/25 µg, 30 µg/10 µg CAZ/AVI disk have significant statistical differences to determinate CAZ/AVI antibacterial activity, but for 30 µg/50 µg disk, there has a cross section between susceptible isolates (minimum 20.5 mm) and resistance isolates (maximum 21.5 mm). For 30 µg/25 µg disk, it is hard to distinguish the difference between susceptible isolates (minimum 19.7 mm) and resistance isolates (maximum 19.2 mm), so 30 µg/10 µg CAZ/AVI disk is more conducive to determinate antibacterial activity.

RESUMO

Economic inequality has been found to be detrimental to psychological well-being. However, previous studies were mostly based on cross-sectional data, drew exclusively on adults, and confined to Western developed countries. To address these shortcomings, the current study investigated the longitudinal association of income inequality with adolescent psychological well-being in a non-Western developing economy (i.e., China). We used the China Family Panel Studies data set with a representative sample of 3,042 adolescents (Mage  = 12.59) from 20 provinces in China. Analyses showed that adolescents in more unequal provinces had lower happiness and more psychological distress. The associations between economic inequality and well-being varied across adolescents from different socioeconomic strata.

RESUMO

BACKGROUND: Children orphaned by parental AIDS or those of parents with HIV infection demonstrate many negative mental health outcomes. Different types of psychosocial interventions have been conducted to improve the psychological well-being of these children. The efficacy of these psychosocial interventions has been reviewed and synthesized recently (Skeena et al., Vulnerable Child Youth Stud 12:91-116, 2017), but not quantified. METHOD: This study therefore adopted meta-analytic approach to quantify the efficacy of the existing psychosocial interventions on depressive and anxiety symptoms in children affected by parental HIV/AIDS. Eight intervention studies-four randomized controlled trials (RCT) and four pre-post intervention trials-were included. RESULT: In general, psychosocial interventions could effectively reduce anxiety or depressive symptoms in children of parents with HIV/AIDS. The overall intervention effect size (Cohen's d) was 1.298 and 1.100 for depressive and anxiety symptoms, respectively. Publication bias and exploratory moderating effects of study design (RCT vs. pre-post intervention trials), study location, and intervention levels were also analyzed. CONCLUSION: Future studies reporting the detailed outcome data, which could be used for research integration, are warranted. Further research should also focus on the implementation of evidence-based interventions sensitive to the target population in a developmentally appropriate manner.

RESUMO

OBJECTIVE: This study seeks to understand the ways in which spouses' gender-related attitudes are configured within couples and how such configurations are linked to marital satisfaction in Chinese marriage. METHOD: Latent profile analysis was conducted using dyadic data from a nationwide large sample of Chinese couples from the China Family Panel Studies (N = 7,257 couples; Myears of marriage = 28.36, SD = 12.84; Mage for wives = 52.38, SD = 12.63; Mage for husbands = 50.51, SD = 12.37). RESULTS: Four profile groups were identified: the "modern female and traditional male" group (MFTM); the "traditional female and modern male" group; the "child-oriented" group; and the "traditional female and traditional male" group. Husbands' and wives' marital satisfaction varied across groups in different patterns (yet all relevant effect sizes were modest). In general, husbands in the congruent group reported higher satisfaction than did those in the incongruent groups, whereas wives in the "MFTM" group reported lower satisfaction than did those in the other groups. CONCLUSIONS: Such findings shed light on the understudied heterogeneity that inherently exists in the within-couple patterning of gender-related attitudes and its implications for marital well-being in a Chinese cultural context.

RESUMO

RGO/SnO 2 nanocomposites were prepared by a simple blending method and then airbrushed on interdigitated electrodes to obtain the corresponding gas sensors. The characterizations of SEM, TEM, Raman, XRD and FTIR were used to characterize the microstructures, morphologies and surface chemical compositions of the nanocomposites, indicating that the two materials coexist in the composite films and the concentration of surface defects is affected by the amount of SnO 2 nanoparticles. It is also found that the room temperature sensing performance of RGO to NO 2 can be improved by introducing appropriate amount of SnO 2 nanoparticles. The enhanced NO 2 sensing properties are attributed to the rough surface structure and increased surface area and surface defects of the nanocomposite films. Since further reduction of RGO, heat treating the sensing films resulted in a decrease in the response and recovery times of the sensors. Furthermore, the sensor annealed at 200 ∘ C exhibited a small baseline drift, wide detection range, good linearity, high stability and better selectivity.

RESUMO

An reduced graphene oxide (RGO) resistive gas sensor was prepared to detect ammonia at room temperature, the result indicated that the desorption of gas (NH 3 ) molecules from a graphene-based sensor was difficult, which lead to a baseline drift. The responses of different concentrations were compared and studied. It was found that both the response rate and its acceleration were affected by the gas concentration. An Intermolecular Forces Based Model was established to explain the adsorption and desorption dynamic response curves. A new method was proposed based on this model. The first and second derivative extrema (FSDE) of the response curve can be attained quickly to calibrate the gas concentrations. The experiment results demonstrated that this new method could eliminate the baseline drift and was capable of increasing the efficiency of gas calibration significantly.

RESUMO

Despite substantial global efforts to reduce HIV-related stigma, stigma and discrimination remain widespread and are among the most poorly understood aspects of the epidemic. However, there has been little research on whether HIV stigma in a country is associated with HIV prevalence. This article offers a socioecological perspective for understanding HIV stigma in a context of HIV prevalence. Using two international data sets (the UNAIDS 2009 HIV Epidemiological Report and the World Values Survey), we investigated whether and how HIV prevalence is associated with individual- and country-level HIV stigma. Results showed that in countries with higher HIV prevalence, people reported less HIV stigma (Studies 1 & 2). HIV knowledge mediated the relationship between HIV prevalence and stigma (Study 2). People in countries with higher HIV prevalence reported more knowledge about HIV transmission, which reduced their stigmatizing attitudes. These findings suggest that stigma-reduction programs should incorporate a socioecological perspective and consider the roles of prevalence rate of and knowledge of the disease.

RESUMO

Meaning in life has been posited to improve psychological well-being. People facing adversities can reduce psychological distress through pursuing a sense of purpose in life. However, the effectiveness of meaning in life in promoting psychological well-being has been found varied, and what factors may affect the function of meaning in life remain unclear. In this paper, the authors suggest that resilience, the positive adaptation during or following significant adversity, can strengthen the protective effects of meaning in life on psychological well-being. To test this hypothesis, we analyzed data from a sample of 518 vulnerable children of parents living with HIV about their meaning in life, resilience, depression, and loneliness. Results showed that resilience moderated the relationship between meaning in life and depression, and between meaning in life and loneliness. Meaning in life was associated with lower levels of depression and loneliness among children high in resilience, in comparison to children low in resilience. Future interventions targeting meaning in life and well-being should consider children's resilience, which can allow for better individualization of the treatment.

RESUMO

Eleven new monoterpenoids including three 1-methyl cantharimide-type derivatives (1-3), five 1,2-dimethyl cantharimide-type derivatives (4, 5, 7-9), and three 1-hydroxymethyl-2-methyl cantharimide-type derivatives (10-12), together with seven known cantharimides (6, 13-18), were isolated from Mylabis phalerata Palla. The planar structures and absolute configurations of compounds 1-14 were fully elucidated on the basis of spectroscopic analysis, ECD spectra, single-crystal X-ray diffraction analysis, and chemical methods. Compounds 6, 15, 16, and 18 were found to be potent inhibitors of HBV virus, with IC50 values of 62, 42, 58, and 19 µM.

RESUMO

Previous studies have shown that depression is negatively associated with hope and social support. However, little research has been undertaken to investigate the theoretical mechanisms underlying the connections among hope, social support, and depression. This study examined how two types of self-esteem (personal and relational) would mediate the relationship of hope and social support to depression among 384 Hong Kong adolescents (age: 12-18 years; M = 14, SD = 1.19). Participants reported their levels of hope, social support, personal self-esteem, relational self-esteem, and depressive mood. Results of the path analysis showed that both personal and relational self-esteem mediated the associations of hope and social support with depression. Hope and social support were associated with higher levels of personal and relational self-esteem, which were in turn related to decreased levels of depression. Theoretical and practical implications are discussed.
