Sesame Street is broadcast to millions of children globally, including in some of the world's poorest regions. This meta-analysis examines the effects of children's exposure to international co-productions of Sesame Street, synthesizing the results of 24 studies, conducted with over 10,000 children in 15 countries. The results indicated significant positive effects of exposure to the program, aggregated across learning outcomes, and within each of the three outcome categories: cognitive outcomes, including literacy and numeracy; learning about the world, including health and safety knowledge; social reasoning and attitudes toward out-groups. The effects were significant across different methods, and they were observed in both low- and middle-income countries and also in high-income countries. The results are contextualized by considering the effects and reach of the program, relative to other early childhood interventions. 相似文献

The use of parenting measures that are developed for use with Western families without testing their validity among families from non-Western cultural backgrounds may not be appropriate. Similar parenting behaviors may affect child outcomes in different ways across different cultures. This study examined the cross-cultural validity of an observational Maternal Responsiveness coding system and of self-reports of lax/inconsistent parenting in Euro–Canadian (n = 23) and East Asian immigrant mothers (n = 23) of 4- to 7-year-old sons. In Euro–Canadian mothers, observed parenting responsiveness was associated with less lax/inconsistent parenting and fewer child behavior problems. In East Asian immigrant mothers, however, observations of greater responsiveness were not related to reports of lax/inconsistent parenting, and were associated with greater child behavior problems. Implications for the use of these parenting measures across culture groups are discussed. 相似文献

Results from impedance spectroscopy measurements at temperatures between 400 and 1000°C, for single crystal and highly pure and dense polycrystalline α-Al2O3 samples with well-defined grain size, are compared with that from molecular dynamics calculation. Between 650 and 1000°C, the measured activation energy for conductivity is 1.5?eV for the single crystal, and increases from 1.6 to 2.4?eV as the grain size decreases from 15 to 0.5?µm. The molecular dynamics calculation leads to the conclusion that the self-diffusion activation energy is about 1.5?eV for O and 1.0?eV for Al in single crystal α-Al2O3. The much higher mobility of O ions makes the O ions responsible for the conductivity of the single crystal oxide. It seems that the grain boundary leads to an increase in the activation energy. However, the quantitative influence of grain boundary still needs to be explained. Between 400 and 650°C, the measured activation energy is about 1.0?eV and independent of the grain size. 相似文献

The constructive episodic simulation hypothesis suggests that we imagine possible future events by flexibly recombining details of past experiences to produce novel scenarios. Here we tested this hypothesis by determining whether episodic future thinking is related to relational memory ability during the preschool years. Children (3- to 5-year-olds) were asked to remember a past event and imagine a possible future event using an adapted version of the recombination paradigm. Relational learning and inference were assessed using a task adapted from the neuroimaging literature. The results show that preschoolers were able to describe both past and possible future events; however, they produced more specific episodic details in relation to past events relative to future events. Episodic future thinking performance was correlated with performance on the relational inference task, consistent with the idea that the ability to flexibly recombine relational knowledge is critical in episodic future thinking. 相似文献

The Internet has emerged as an important communication platform for the support of collective action, but little is known about how it influences the psychosocial motives for participation. Two quantitative studies were conducted within two different mobilizing contexts, in which offline collective actions were launched through computer‐mediated communication. We examined whether and how the frequency with which people participated in online political discussions moderated the effects of the psychosocial predictors of collective action, specifically politicized identity, anger, collective efficacy, and morality. Results showed that collective action intention was predicted by politicized identity only when participants reported a higher versus lower frequency of online discussion. However, anger did not predict collective action when people had the chance to express this emotion through a higher versus lower frequency of online discussion. Moreover, collective efficacy and morality supported collective action intention in participants who reported a higher versus lower frequency of online discussion. We theorize on how computer‐mediated communication, and its specific features, can be studied as a mobilizing context that influences the psychosocial motives to participate in collective action.

This article uses the Theory of Gender and Power to examine women's vulnerability to HIV/AIDS in order to: understand the vulnerability of female sex workers/poor women due to poverty and lack of educational resources; explore women's vulnerability in the context of client/partner violence, alcohol use, male partner's high-risk behaviors, and women's lack of control in their intimate relationships; and explore the role of traditional heterosexual gender norms in the outcomes of sexual negotiation. Ethnographic data were collected from 32 women and 38 men in India as part of an ongoing National Institute of Mental Health study. Results highlighted women's vulnerability to HIV/AIDS stemming from partner violence, alcohol use, poverty, dangers of sex work environments, and tacit acceptance of cultural/gender norms. 相似文献

Young people with borderline personality disorder (BPD) commonly seek help but often go unrecognized. Screening offers a means of identifying individuals for more detailed assessment for early intervention and for research. AIMS: This study compared the McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), Borderline Personality Questionnaire (BPQ), the BPD items from the International Personality Disorder Examination Screening Questionnaire and the BPD items from the Structured Clinical Interview for DSM-IV Axis II disorders (SCID-II) Personality Questionnaire. METHOD: 101 outpatient youth (aged 15-25 years) completed the screening measures and were interviewed, blind to screening status, with the SCID-II BPD module. The screening measures were readministered two weeks later to assess test-retest reliability. RESULTS: All four instruments performed similarly but the BPQ had the best mix of characteristics, with moderate sensitivity (0.68), the highest specificity (0.90), high negative predictive value (0.91) and moderate positive predictive value (0.65). Compared to the other three instruments, the BPQ had the highest overall diagnostic accuracy (0.85), a substantially higher kappa (0.57) with the criterion diagnosis, the highest test-retest reliability (ICC = 0.92) and the highest internal consistency (alpha = 0.92). The only clear difference to emerge in the Receiver Operator Curve (ROC) analysis was that the BPQ significantly outperformed the MSI (p = 0.05). CONCLUSION: Screening for BPD in out-patient youth is feasible but is not a replacement for clinical diagnosis. 相似文献
