Intergenerational Caregiving Patterns and Cognitive Health among the Sandwich Generation Within Four-Generation Families.

This study aims to investigate whether generational differences in intergenerational caregiving patterns (caring for parents only, caring for grandchildren only, and caring for parents and grandchildren simultaneously) are associated with cognitive health disparities among the sandwich generation within four-generation families, drawing upon the theories of intergenerational solidarity and intergenerational stake. Moreover, this study seeks to identify mediators that help explain these disparities. A nationally representative sample of 8,065 respondents was drawn from the 2011 and 2018 waves of the China Health and Retirement Longitudinal Study. The findings reveal that the sandwich generation caring for grandchildren only, as well as those caring for grandchildren and parents simultaneously, exhibit better cognitive health. However, caregiving for parents only is not significantly related to their cognitive health. This study identifies the inability to reduce depressive symptoms as a mediator explaining the insignificant association between caregiving for parents only and the cognitive health of the sandwich generation. The findings underscore the importance of offering support to the sandwich generation within four-generation families to enhance their cognitive health. Moreover, it is imperative to distinguish between different intergenerational caregiving patterns based on generational differences among the sandwich generation, with a specific emphasis on allocating public resources aimed at promoting cognitive health for those engaged in caring for parents.

The Effect of Ostracism on Adults' Materialism: The Roles of Security and Self-Construal.

With consumer culture becoming more prominent, the value of materialism is growing rapidly. This study explored the formation of materialism in adults, based on the temporal need-threat model of ostracism and the theory of materialistic values. Specifically, this study examined the link between ostracism and materialism from the perspective of security and the moderating role of self-construal in this process. A sample of 1,272 Chinese adults (M age = 35.90 ± 11.59, 47.2% male) was recruited to complete the Ostracism Experiences Scale, the Material Values Scale, the Security Questionnaire, and the Self-Construal Scale. The results showed that (1) ostracism positively predicted materialism in Chinese adults; (2) security partially mediated the relationship between ostracism and materialism; (3) and self-construal moderated this mediation model. The moderating effect of self-construal on the relationship between ostracism and security was significant. Specifically, the direct effect of ostracism on security was much stronger for adults with interdependent self-construal than for those with independent self-construal. However, self-construal had no significant moderating effect on the direct effect of ostracism on materialism. These findings suggest that ostracism may affect materialism by damaging adults' feelings of security, and independent self-construal can buffer the damage of ostracism on security.

The mechanisms underlying the negative effect of depression on life satisfaction among the elderly: the roles of ostracism and economic income.

OBJECTIVES: Depression is prevalent among older persons, which seriously threatens their life satisfaction. This study aimed to explore the internal mechanisms by which depression influences life satisfaction among the elderly, as well as the mediating and moderating effects of ostracism and economic income, respectively, in a sample of rural older adults across China. DESIGN: This was a cross-sectional survey conducted as part of the project "Thousands of People and Hundreds of Villages (2019)." SETTING: Participants were rural older adults from 31 provincial-level administrative units across China. PARTICIPANTS: The sample composed of 1,754 participants aged 60 years and over. MEASUREMENTS: Depression was assessed with the depression subscale of the Depression Anxiety Stress Scales, life satisfaction with the Satisfaction with Life Scale, ostracism with the Ostracism Experience Scale (OES), and economic income and other control variables with related demographic scales. Moderation and mediation analyses were performed using the regression-based approach as conducted by Hayes (). RESULTS: Depression negatively predicted life satisfaction among the elderly. Ostracism played a partially mediating role between depression and life satisfaction. Economic income moderated the effect of depression and ostracism on life satisfaction: High economic income weakened the negative effect of depression on life satisfaction and enhanced the negative effect of ostracism on life satisfaction. CONCLUSION: Improving depressed elderly people's interpersonal relationships and financial support could improve their life satisfaction.

Workplace Ostracism and Counterproductive Work Behaviors: The Chain Mediating Role of Anger and Turnover Intention.

This study aims to explore the mediating effect of anger and turnover intention on the relationship between workplace ostracism and counterproductive work behaviors. A two-stage follow-up survey of 426 employees born after 1990 was conducted using the Workplace Ostracism Scale, Counterproductive Work Behaviors Scale, Trait Anger subscale of the State-Trait Anger Expression Inventory, and Turnover Intention Scale. Workplace ostracism was found to be significantly positively correlated with anger, turnover intention, and counterproductive work behaviors. Furthermore, anger and turnover intention both separately and serially mediated the relationship between workplace ostracism and counterproductive work behaviors. This study confirms the chain mediating effect of anger and turnover intention on the relationship between workplace ostracism and counterproductive work behaviors.

Low Altruism as a Cause of Ostracism.

This study focused on the causes of ostracism and explored the relationship between altruistic personality traits and ostracism. Using a combination of questionnaire surveys and laboratory experiments, results showed that: individuals with lower altruism were more vulnerable to be ostracized than those with higher altruism (Study 1 and Study 2). The relationship between altruism and ostracism was partially mediated by social responsibility (Study 3). When facing a low-altruistic target, the source would infer that the social responsibility level of this target was also low, thereby leading the ostracism intention to the target. Empathy did not moderate the relationship between altruism and ostracism. On the one hand, empathy did not moderate the direct effect of altruism on ostracism (Study 2); on the other hand, it also did not moderate the mediating role of social responsibility (Study 3). The strengths and limitations of this research are also discussed.

Effects of security on social trust among Chinese adults: Roles of life satisfaction and ostracism.

The study aims to explore the effect of security on social trust and the roles of life satisfaction and ostracism among Chinese adults. Toward this end, the study recruited 1,206 Chinese adults to complete the Security Questionnaire, Social Trust Questionnaire, Satisfaction with Life Scale, and Ostracism Experiences Scale. Results show that (a) security is positively correlated with social trust among Chinese adults, (b) life satisfaction partially mediates the effect of security on social trust, and (c) ostracism moderates the relationship between security and social trust. Furthermore, findings indicate that security can directly predict social trust as well as indirectly predict social trust through life satisfaction for adults in China. Security has a strong predictive effect on social trust - especially for individuals with low levels of ostracism.

Association Between Job Stress and Organizational Commitment in Three Types of Chinese University Teachers: Mediating Effects of Job Burnout and Job Satisfaction.

Utilizing the Job Demands-Resources (JD-R) model as the theoretical framework, this study examines the relationship between job stress, job burnout, job satisfaction, and organizational commitment among 1,906 university teachers in China, and investigates teachers' differences across groups. The result of SEM indicates that job burnout and job satisfaction could play mediating roles between job stress and organizational commitment. The result of multi-group analysis shows that for national university teachers, the positive effect of job stress on job burnout is the highest among three types of university teachers, the negative effect of job burnout on organizational commitment is lower compared with provincial university teachers and the negative effect of job burnout on job satisfaction is lower compared with provincial university teachers. Only for provincial university teachers, the job stress can significantly positively predict organizational commitment, and the independent mediating effect of job burnout is significantly greater than job satisfaction. The practical advice to enhance Chinese university teachers' organizational commitment was provided in the end.

Ostracism Increases Automatic Aggression: The Role of Anger and Forgiveness.

While research on the "ostracism-aggression" link has focused on controlled processes in aggression, little effort has been devoted to examining the relation between ostracism and automatic aggression. Based on theories of aggression, we found that ostracized participants reported higher levels of automatic aggression than included participants (Studies 1 and 2). Furthermore, the association between ostracism and automatic aggression was mediated by anger and was especially prominent for people low in forgiveness (as compared to people high in forgiveness; Study 3). The implications of these findings are discussed.

Relationships Between Social Support, Loneliness, and Internet Addiction in Chinese Postsecondary Students: A Longitudinal Cross-Lagged Analysis.

Using the Internet has become one of the most popular leisure activities among postsecondary students in China. Concern about the large number of students using the Internet has led to an increase in research on the influencing factors of Internet addiction and the negative consequences caused by it. This short-term longitudinal study examined the associations among three dimensions of social support [objective support (OS), subjective support (SS), and support utilization (SU)], loneliness, and the four dimensions of Internet addiction (compulsive Internet use [CIU] & withdrawal from Internet addiction [WIA], tolerance of Internet addiction [TIA], time-management problems [TMPs], and interpersonal and health problems [IHPs]) in a Chinese sample. A total of 169 postsecondary first-year students (88 girls and 81 boys; mean age = 18.31 years) participated in the study. The questionnaire measurements were taken at the beginning of the school year (T1), 6 months later (T2), and 1 year later (T3). Cross-lagged and structural equation modeling analyses indicated that (a) OS (T1) and SU (T1) negatively predicted loneliness (T2); and loneliness (T2) negatively predicted OS (T3) and SU(T3); (b) CIU & WIA (T1) and TMPs (T1) positively predicted loneliness (T2); and loneliness (T2) positively predicted CIU & WIA (T3), TIA (T3), TMP (T3), and IHP (T3); (c) SS (T1) directly affected TIA (T3) and TMP (T3); and (d) loneliness (T2) played a mediating role in the relationships between OS (T1) and CIU (T3), OS (T1) and TMP (T3), OS (T1) and IHP (T3), and SU (T1) and IHP (T3). Finally, interventions for Internet addiction and implications for future studies were discussed.

Preparation and Characterization of Methylene Blue-Incorporated Folate-Functionalized Fe3O4/Mesoporous Silica Core/Shell Magnetic Nanoparticles.

In the present work, a multifunctional nanomaterial, methylene blue-incorporated folate-functionalized Fe3O4/mesoporous silica core/shell magnetic nanoparticles, has been developed. Firstly, highly biocompatible monodisperse superparamagnetic Fe3O4@mSiO2 core/shell nanoparticles with mesoporous silica shells were synthesized. Then these particles were coated with the covalently bonded biocompatible polymer poly(ethylene glycol) (PEG) and modified with the cancer targeting ligand folic acid (FA). Finally, the water-soluble photosensitizer methylene blue (MB) was loaded into the mesoporous silica shell. Systematic experiments were performed to carefully evaluate the physical and chemical properties, cytotoxicity and cellular uptake of the multifunctional nanomaterial.

A functional drug delivery platform for targeting and imaging cancer cells based on Pluronic F127.

Functional polymeric micelles play an important role in the efficient delivery of therapeutic drugs into tumours. In this study, a functional drug delivery platform with ligands for targeting and fluorescent imaging was designed based on Pluronic F127 (PF127). Using folic acid (FA) and fluorescein isothiocyanate (FITC) to chemically conjugate with PF127, two functional polymers, Pluronic F127-FA (PF127-FA) and Pluronic F127-FITC (PF127-FITC), were synthesized. Solasodine-loaded micelles were then prepared via the thin-film hydration method. By employing A549 and HeLa cells, the results of in vitro cell assays performed using confocal laser scanning microscopy and flow cytometry suggested that the proposed micelles could provide the desired specific targeting and fluorescent imaging functions. In addition, the results of in vitro cytotoxicity experiments showed that the growth inhibition rates of A549 and HeLa cells treated with solasodine-loaded micelles were remarkably higher than those of cells treated with free solasodine. Solasodine-loaded micelles exhibited a more distinct inhibitory effect against HeLa cells than against A549 cells. Thus, an effective drug delivery system for targeting and imaging cancer cells was developed.

Physical attractiveness, attitudes toward career, and mate preferences among young Chinese women.

We examined young Chinese women's mate preferences as a function of their self-perceived attractiveness and career attitudes. A total of 264 young Chinese women rated their own attractiveness, reported their attitudes toward career, and rated the importance of 20 mate characteristics. The characteristics encompassed four facets that individuals typically consider when seeking a long-term mate: good-genes indicators, good investment ability indicators, good parenting indicators, and good partner indicators. We found that both self-perceived attractiveness and attitudes toward career were positively associated with the importance attached to several of the characteristics. Moreover, women who had high career focus but low self-perceived attractiveness attached more value to intelligence, ambition, and industriousness than women who had low career focus but high self-perceived attractiveness; women with low career focus but high self-perceived attractiveness attached more value to physical attractiveness in a mate than women with high career focus but low self-perceived attractiveness. We discussed the limitations of our research and directions for future research.
