Chinese adolescents' positive relationships with parents: The effects of the sex of their younger sibling.

We investigated how sibling status and sex of younger siblings influence Chinese adolescents' relationships with their fathers and mothers as a function of resource dilution and preference for sons. The sample included 1,093 adolescents from the 8th grade (Mage  = 13.96 years, SD = 0.75 years; 47% girls) and the 11th grade (Mage  = 17.25 years, SD = 0.74 years; 57% girls) in a longitudinal study. Consistent with expectations pertaining to the hypothesis of resource dilution and son preference in combination, girls with a younger brother reported less positive relationships with mothers than either singleton girls or girls with a younger sister. No significant difference was found between singleton boys and boys with a younger sibling. The current findings show implications that the resource-dilution theory and son preference culture together may place girls with a younger brother in an unfavorable condition of resource allocation.

The asymmetric effect of regulatory fit on moral judgments of other-oriented lies.

We examined whether regulatory fit effects are asymmetric-namely, whether they occur only among individuals with a promotion focus or a prevention focus. We adopted a task where individuals make moral judgments of other-oriented lies and conducted three studies. The results indicated that prevention-focused individuals judged other-oriented lies based on a vigilant strategy as more moral than lies based on an eager strategy (Studies 1 and 2). Meanwhile for promotion-focused individuals, there were no differences between eager and vigilant strategies on moral judgments of other-oriented lies. Additionally, the results suggested that the feeling of rightness is an underlying mechanism of the regulatory fit effects of prevention focus (Study 3).

Physical Illnesses and Medically Serious Suicide Attempts in Rural China.

Background: Physical illness is a strong correlate of suicidal behavior. However, its impact on attempted suicide in rural China is under-studied. Aims: This study was designed to assess the influence of physical illness on risk of suicide attempts and to identify distinguishing characteristics among medically serious suicide attempters with physical illnesses from those without. Method: Participants were medically serious suicide attempters identified through hospital emergency rooms (n = 659) as well as age- and gender-matched community controls (n = 659) from Shandong Province, China. Face-to-face interviews with the respondents were conducted with a semistructured protocol that included sociodemographic and psychological measures. Results: Physical illness was a significant risk factor for medically serious suicide attempts (OR = 1.739, 95% CI = 1.182-2.560). Older age was a significant risk factor, while female gender, no religion, and non-peasant occupations were significant protective factors for suicide attempts with physical illness. Limitations: Samples from only one province may not completely represent all serious suicide attempters in China. Furthermore, we did not assess the severity and the degree to which their physical illness limited the functioning of the individual. Conclusion: Physical illness is an important risk factor for suicide attempts in rural China. More efforts are needed to specifically target older people, males, those with religious beliefs, and peasant workers with physical illness.

Who Gains More? The Relationship Between Parenthood and Well-Being.

Two studies were conducted to explore the effect of parental sex on well-being due to parenthood. Study 1 analyzed the sixth wave of the World Values Survey data. The results indicated that parents were happier than their respective childless peers. However, the effect of motherhood was significantly higher than that of fatherhood. Furthermore, Study 2 analyzed the data from 354 single-child parents in China. The results showed that perceived parent-child facial resemblance moderated the sex difference in well-being. Specifically, in the high parent-child facial resemblance group, both fathers and mothers showed high levels of well-being; however, in the low parent-child facial resemblance group, the well-being level of mothers was higher than fathers. These results supported the renovated pyramid of needs and the hypothesis of paternal uncertainty.

Predicting Substance Use and Deviant Behavior from Prosociality and Sociability in Adolescents.

Social competence is commonly considered an important factor that impedes maladaptive development because individuals who lack adequate competence to direct or control their behaviors in social situations are likely to display problems. Despite the belief that social competence may be a multi-dimensional construct, existing research has not explored the unique contributions of its different aspects to development. The present two-wave longitudinal study examined relations of prosociality and sociability, two major aspects of social competence, with problem behaviors in a sample of adolescents. Peer assessment data on prosociality and sociability and self-report data on substance use and deviant behavior were obtained from a sample of adolescents in middle (N = 657, mean age = 13 years) and high (N = 675, mean age = 16 years) schools in China. The results showed that prosociality negatively predicted later problem behaviors, whereas sociability positively predicted later problem behaviors. In addition, gender and grade moderated the associations between sociability and problem behaviors. More specifically, the positive association between sociability and later substance use was significant for boys, but not for girls. Sociability was also more strongly associated with later substance use in middle school than in high school. The results indicate that prosociality and sociability may have different functional meanings in adolescent development and have implications for practical work with adolescents who display problem behaviors.

Longitudinal associations between popularity and aggression in Chinese middle and high school adolescents.

The longitudinal associations between popularity, overt aggression, and relational aggression were assessed in middle school and high school cohorts drawn from a large urban Northwest Chinese city. The middle school (n = 880; 13.33 years.) and high school samples (n = 841; 16.66 years.) were each followed for 2 years. In the concurrent regression analyses, overt aggression was more strongly and consistently associated with popularity than relational aggression after controlling for likability. Cross-lagged analyses revealed that popularity predicted subsequent increases in overt and relational aggression throughout middle and high school whereas overt aggression at 7th and 10th grade predicted increases in popularity 1 year later. These findings provide further evidence that popularity is associated with aggression and suggest that overt and relational aggression may be a consequence rather than a contributor to popularity in Chinese adolescents.

Self-recovery reversible image watermarking algorithm.

The integrity of image content is essential, although most watermarking algorithms can achieve image authentication but not automatically repair damaged areas or restore the original image. In this paper, a self-recovery reversible image watermarking algorithm is proposed to recover the tampered areas effectively. First of all, the original image is divided into homogeneous blocks and non-homogeneous blocks through multi-scale decomposition, and the feature information of each block is calculated as the recovery watermark. Then, the original image is divided into 4×4 non-overlapping blocks classified into smooth blocks and texture blocks according to image textures. Finally, the recovery watermark generated by homogeneous blocks and error-correcting codes is embedded into the corresponding smooth block by mapping; watermark information generated by non-homogeneous blocks and error-correcting codes is embedded into the corresponding non-embedded smooth block and the texture block via mapping. The correlation attack is detected by invariant moments when the watermarked image is attacked. To determine whether a sub-block has been tampered with, its feature is calculated and the recovery watermark is extracted from the corresponding block. If the image has been tampered with, it can be recovered. The experimental results show that the proposed algorithm can effectively recover the tampered areas with high accuracy and high quality. The algorithm is characterized by sound visual quality and excellent image restoration.

Impact of Adult Attachment Anxiety on Deception Judgments: Examining the Moderating Effect of Motivation.

Several psychologists have paid attention to individual differences in deception detection, but only a few studies have found significant results. The present study aimed to explore the relationship between attachment anxiety and deception judgment when there are no obvious cues to distinguish lies from truth, and to examine the moderating effect of motives. Participants were instructed to judge each of 10 audios on whether they were true or false. Subsequently, the attachment anxiety of participants was assessed using the Experiences in Close Relationships questionnaire. Results revealed that, compared with people who had low attachment anxiety, those with high attachment anxiety tend to have higher truth biases in the low-motive condition and lower accuracy in the high-motive condition.

Gain or non-loss: The message matching effect of regulatory focus on moral judgements of other-orientation lies.

Previous studies found that individuals with promotion focus are more likely to be persuaded by messages framed in terms of gain-related words; individuals with prevention focus are more likely to be persuaded by messages framed in terms of loss-related words. This is known as the message matching effect of regulatory focus. The present study extended this effect into the field of moral judgement of other-orientation lies. Two experiments were conducted, revealing that (a) individuals with promotion focus judged gain-framed other-orientation lies to be more moral, while individuals with prevention focus judged non-loss-framed other-orientation lies to be more moral; and (b) the subjective processing fluency had a partial mediating role in the message matching effect. Theoretical implications and future research directions were discussed.

Tobacco Use by Middle and High School Chinese Adolescents and their Friends.

Understanding the similarity of the tobacco use of youth and their friends and unraveling the extent to which this similarity results from selection or socialization is central to peer influence models of tobacco use. The similarity between the tobacco use of Chinese adolescents and their friends were explored in middle (880, 13.3 years, 399 girls) and high school (849, 16.6 years, 454 girls) cohorts assessed yearly at three times. Boys were more similar to their friends in tobacco use than were girls. Growth curve models revealed escalation of use during middle school and stable use during high school for boys, whereas models for girls could not be computed. Evidence of selection effects emerged from cross-lagged panel analyses revealing pathways from boys' tobacco use to subsequent changes in their friends' use; assessment of selection and influence processes could not be assessed for girls. The results from this study suggest that peer influence processes may differ for Chinese boys and girls and that further quantitative and qualitative research is necessary to understand these processes.

In Situ Measurement of Voltage-Induced Stress in Conducting Polymers with Redox-Active Dopants.

Minimization of stress-induced mechanical rupture and delamination of conducting polymer (CP) films is desirable to prevent failure of devices based on these materials. Thus, precise in situ measurement of voltage-induced stress within these films should provide insight into the cause of these failure mechanisms. The evolution of stress in films of polypyrrole (pPy), doped with indigo carmine (IC), was measured in different electrochemical environments using the multibeam optical stress sensor (MOSS) technique. The stress in these films gradually increases to a constant value during voltage cycling, revealing an initial break-in period for CP films. The nature of the ions involved in charge compensation of pPy[IC] during voltage cycling was determined from electrochemical quartz crystal microbalance (EQCM) data. The magnitude of the voltage-induced stress within pPy[IC] at neutral pH correlated with the radius of the hydrated mobile ion in the order Li(+) > Na(+) > K(+). At acidic pH, the IC dopant in pPy[IC] undergoes reversible oxidation and reduction within the range of potentials investigated, providing a secondary contribution to the observed voltage-induced stress. We report on the novel stress response of these polymers due to the presence of pH-dependent redox-active dopants and how it can affect material performance.

The Effect of Perceived Parent-Child Facial Resemblance on Parents' Trait Anxiety: The Moderating Effect of Parents' Gender.

Father-child facial resemblance is an important cue for men to evaluate paternity. Previous studies found that fathers' perceptions of low facial resemblance with offspring lead to low confidence of paternity. Fathers' uncertainty of paternity could cause psychological stress and anxiety, which, after a long time, may further turn into trait anxiety. Conversely, females can ensure a biological connection with offspring because of internal fertilization. The purpose of this study was thus to examine the role of parents' gender in the effect of parents' perceived facial resemblance with child on their trait anxiety. In this study, 151 parents (father or mother) from one-child families reported their facial resemblance with child and their trait anxiety. Results showed that (i) males tended to perceive higher facial similarity with child than did females and (ii) males' perceived facial resemblance with child significantly predicted trait anxiety, whereas females' perceived facial resemblance did not. These findings suggested that the uncertainty of paternity contributed to the trait anxiety of fathers, but not mothers.

Ethnic identity salience improves recognition memory in Tibetan students via priming.

OBJECTIVES: Social identity salience affects group-reference effect in memory. However, limited studies have examined the influence of ethnic identity salience on group-reference effect among minority group people in conditions where the minority group dominates. In the present research, we aim to investigate, in a Tibetan-dominant context, whether the salience of ethnic identity among Tibetan students could display an influence on their group-reference effect via priming method. METHOD: We recruited 50 Tibetan and 62 Han Chinese students from Tibetan University in Lhasa, the capital of Tibet Autonomous Region, where Tibetans were the majority. A month before the experiment, we tested the baseline of ethnic identity salience of both Tibetan and Han Chinese students using the Twenty Statements Test. In the formal experiment, we assessed the effectiveness of priming method first and then conducted a recognition memory test 2 week later via priming approach. RESULTS: The results showed that the ethnic identity both of Tibetan and Han Chinese participants was not salient in the baseline assessment. However, it was successfully induced via priming among Tibetan students. Tibetan students showed a significant group-reference effect in recognition memory task when their ethnic identity was induced via priming. On the contrary, Han Chinese students did not show increased ethnic awareness and superiority of ethnic in-group reference memory after being primed. CONCLUSIONS: Current research provides new evidence for the influence of salience of ethnic identity on group-reference effect, contributing to the application and extension of social identity theory among minority group people.

The impact of social support on postpartum depression: The mediator role of self-efficacy.

This study aimed to investigate the impact of perceived social support on the depression of postpartum women, and mainly focuses on confirming the mediator role of self-efficacy. A total of 427 new mothers from two general hospitals in Beijing accomplished the Multidimensional Scale of Perceived Social Support, General Self-efficacy Scale, and Edinburgh Postnatal Depression Scale. The results revealed that both social support and self-efficacy significantly correlate with postpartum depression. Structural equation modeling indicated that self-efficacy partially mediates the relationship between social support and postpartum depression.

The impact of power on humanity: self-dehumanization in powerlessness.

Power gives people the ability to control themselves and their environment, and this control is considered a fundamental human need. We investigated whether experiencing powerlessness induces the experience of self-dehumanization using three methods: priming, role-playing, and cueing. People in a position of low power viewed themselves (Experiments 1-3) as less human relative to people in a position of high power; furthermore, people with low power believed that they were viewed as less human by others as well (Experiments 2-3). In all of the experiments, human nature traits were most negatively affected by powerlessness in self-perception judgments, and uniquely human traits were most negatively affected by powerlessness in meta-perception judgments. Furthermore, the powerless believed they were viewed as less human not only by the powerful people but also the outside observers of the power dynamic. Self-dehumanization also appears to be a consequence of powerlessness rather than an incidental result of a change in mood or a negative self-view. Our findings are an important extension of previous work on the adverse effects of powerlessness and dehumanization.

Is the excessive use of microblogs an Internet addiction? Developing a scale for assessing the excessive use of microblogs in Chinese college students.

More and more college students are using microblogs, with some excessive users demonstrating addiction-like symptoms. However, there is currently no published scale available for use in assessing excessive use of these microblogs, a significant impediment to advancing this area of research. We collected data from 3,047 college students in China and developed a Microblog Excessive Use Scale (MEUS) for Chinese college students, comparing it with criteria used for assessing Internet addiction. Our diagnostic scale featured three factors, two of which--"withdrawal and health problem" and "time management and performance"--are already included in Internet addiction assessment scales. The third factor, "social comfort," does not appear in Internet addiction assessment scales. Our study found that females have significantly higher MEUS scores than males, and that total MEUS scores positively correlated with scores from "self-disclosure" and "real social interaction" scales. These findings differ from results obtained in previous investigations into Internet addiction. Our results indicate that some characteristics of the excessive use of microblogs are different to those of Internet addiction, suggesting that microblog overuse may not correspond exactly to the state of Internet addiction.

The bad apple effect and social value orientation in public-goods dilemmas: replication and extension of research findings.

Two studies were conducted to replicate and extend previous findings on the effect of uncooperative behavior on group cooperation (the "bad apple" effect). Study 1 (56 women, 40 men; M age = 23.5 yr.) manipulated information about contributions from the bad apple, controlling for overall contributions to a group account. Study 2 (50 women, 34 men; M age = 20.4 yr.) compared the effects of a bad apple and a good apple on cooperation. The social value orientation of participants was measured to explore individual differences in the bad apple effect. The results revealed a bad apple (a) decreased cooperation among individuals with proself and prosocial orientations in Study 1, and (b) had a greater effect than a good apple on those who were proself compared to prosocial in Study 2.

Motivational cues: the role of perceived senders' self-control ability in raters' deception judgements.

Previous studies have found that senders' personal traits may be used by others to make judgements about the senders' truthfulness. Two studies were conducted to examine whether perceived self-control ability has an effect on deception judgement. Perceived self-control was hypothesized to act as a motivational cue that participants would use to assess the sender's motivation to lie, which in turn would influence their deception judgement. Results revealed that when participants assessed the sender as having higher self-control ability, they would consider the sender to be less motivated to lie in daily life (Study 1), and judge the sender more truthful in a text-based deception judgement task (Study 2). However, the effect of perceived self-control ability disappeared in a video-based task (Study 2), likely due to the multitude of various cues available in audio-visual stimuli. The theoretical and applied implications of the results are discussed.

[Detection of serum autoantibodies to melanocyte and correlation between melanoma antigen recognized by T-cells and vitiligo in children].

OBJECTIVE: To detect the serum levels of melanocyte antibodies and explore the relation between melanoma antigen recognized by T-cells (MART-1) and vitiligo in children. METHODS: The serum samples were collected from children with vitiligo to test the autoantibodies, and divided into low- and high-titer group according to the test results. Melanocytes were incubated with the serum samples, and the changes of melanocyte surface antigen were evaluated using specific MART-1 antibody. RESULTS: The serum melanocyte antibody levels in children with vitiligo were significantly higher than those in normal subjects. The expression level of melanocyte surface antigen MART-1 increased obviously after incubation of the melanocyte with high antibody titer serum samples, and MART-1 was found to specifically bind to specific MART-1 antibody. CONCLUSION: Melanocytes MART-1 may correlate to the autoimmune mechanism in children with vitiligo.

Disability and work-related attitudes in employers from Beijing, Chicago, and Hong Kong.

Employers are primary and necessary agents in the return of people with disabilities to the work force. In this study, employment attitudes about two key constructs for vocational rehabilitation are examined: hiring the person with a disability and accommodating the person with disabilities at work. One hundred employers from Beijing, Hong Kong, and Chicago were surveyed regarding their attitudes. Results showed employers from Beijing were less likely to endorse hiring people with disabilities compared with those from Chicago and Hong Kong. In addition, people with psychiatric disabilities were less likely to be hired compared with those with physical disabilities. No clear pattern by city emerged for accommodations. Reasons why this pattern of attitudes emerged are discussed. Implications of these findings for attitude change are also considered.
