In the framework of meta‐analysis, moderator analysis is usually performed only univariately. When several study characteristics are available that may account for treatment effect, standard meta‐regression has difficulties in identifying interactions between them. To overcome this problem, meta‐CART has been proposed: an approach that applies classification and regression trees (CART) to identify interactions, and then subgroup meta‐analysis to test the significance of moderator effects. The previous version of meta‐CART has its shortcomings: when applying CART, the sample sizes of studies are not taken into account, and the effect sizes are dichotomized around the median value. Therefore, this article proposes new meta‐CART extensions, weighting study effect sizes by their accuracy, and using a regression tree to avoid dichotomization. In addition, new pruning rules are proposed. The performance of all versions of meta‐CART was evaluated via a Monte Carlo simulation study. The simulation results revealed that meta‐regression trees with random‐effects weights and a 0.5‐standard‐error pruning rule perform best. The required sample size for meta‐CART to achieve satisfactory performance depends on the number of study characteristics, the magnitude of the interactions, and the residual heterogeneity. 相似文献

AbstractTen years ago, I was a researcher with the Evaluation of Children’s Trusts which examined a key aspect of U.K. government policy, Every Child Matters. Every Child Matters was partly a response to Lord Laming’s 2003 report into the murder of 8-year old Victoria Climbié, which concluded that children’s services needed to be better integrated to avoid such tragedies in the future. Children’s Trusts were regional hubs, set-up across England to facilitate integrated professional practice; but Every Child Matters was bigger than this because it set out a policy vision for rethinking the child as a whole person. At the time, I was struck by the absence of any reference to spirituality in this new holistic view of the child, and this led me to write an article which was published in 2006 entitled, ‘Every Child Matters and children’s spiritual rights: does the new holistic approach to children’s care address children’s spiritual well-being?’.This article was originally a keynote talk at the 2016 International Conference on Children’s Spirituality with the theme Spirituality and the whole child: interdisciplinary approaches, and this provided the opportunity both to see where we are now with integrated working for children and young people more generally, and to focus our attention on interdisciplinary approaches to children’s spirituality and the whole child in particular. The article begins by summarising some of the current thinking spirituality, the whole child and interdisciplinary working. The article then goes on to consider a long-standing concern of mine, and one which was highlighted in my 2006 article, which is what we intend to mean – collectively, as academics and professional practitioners concerned with children’s (and adults’) spirituality – when we use the term ‘spirituality’ in the professional context. In my view, it is time to stop stating that spirituality is hard to define, and come to an agreement about what we mean when we use it. Interdisciplinary approaches to children’s (and adults’) spirituality, and holistic approaches to the child (and adult), will not be successful unless there is a clear, shared agreement about what we mean, and the article ends with suggestions for ways forward. 相似文献

Countries have adopted different laws, policies, and practices that allow immigration officers to request in certain cases DNA tests to confirm biological relationships in the context of family reunification. In Canada, Citizenship and Immigration Canada has adopted a policy of suggesting DNA testing only as a last resort in cases where no documentary evidence has been submitted or where the evidence provided is deemed unsatisfactory. However, in practice, there have been concerns on the increasing use of DNA tests in family reunification processes of nationals from certain regions including Africa, Asia, and Latin America. Moreover, the Immigration and Refugee Protection Regulations (IRPR) presents a biological definition of family as a determinant of parenthood in the context of family reunification that is inconsistent with the psychosocial definition used in provincial family laws. Although there are cases that can justify the request for DNA tests, there are also significant social, legal, and ethical issues, including discrimination and unfair practices, raised by this increasing use of genetic information in immigration. This policy brief identifies points to consider for policymakers regarding the use of DNA testing in Canadian family reunification procedures. These include (1) the need to refine the policy of “using DNA testing as a last resort” and its implementation, (2) the need to modify the definition of “dependent child” under the IRPR to reflect the intrinsic reality of psychosocial family ties, and (3) the importance of conducting more research on the use of DNA testing in other immigration contexts. 相似文献

The moderating effect of parental warmth on the association between spanking and child aggression: a longitudinal approach 总被引:1,自引:0,他引:1
Ann Michele Stacks Toko Oshio Jean Gerard Jacqueline Roe 《Infant and child development》2009,18(2):178-194
Using data from the Early Head Start Research and Evaluation Study, this study analysed the stability of child aggressive behaviour beginning in infancy and tested whether spanking when the child was 36 months was associated with aggressive child behaviour among three ethnic groups and whether maternal warmth moderated the effect of spanking on aggressive behaviour in each ethnic group at 36 months, after controlling for earlier aggressive behaviour. Participants included 693 Hispanic parent–child dyads, 1013 African‐American dyads and 1086 Caucasian dyads who met qualifications for participation in the Early Head Start programme. Findings suggest that infant temperament was associated with aggressive behaviour at 24 and 36 months and that child aggression remained stable. Among the three ethnic groups, spanking was only associated with aggressive behaviour for children who had Caucasian mothers and maternal warmth did not moderate the effect of spanking on aggressive behaviour.

This study considers the relationship between perfectionism and perceptions of work–family conflict. A situational component to perfectionism was found, with higher standards and a higher perceived discrepancy between standards and performance at home versus at work. Findings suggest perfectionism predicts work–family conflict, beyond the effects of the Big Five, trait affectivity and achievement. Further, findings indicate those with adaptive perfectionism (AP; work and home) tend to have lower strain and time‐based family interfering with work and lower behaviour‐based work interfering with family, compared with maladaptive perfectionists (home) and non‐perfectionists (work and home). Gender differences were found and considered in a more exploratory manner. 相似文献

The current study examined the potential mediating role of sensation seeking in the well-established negative relationship between age and financial risk-taking. A total of 299 participants, aged 17–90 years, allocated hypothetical money into mutual funds that varied in risk and completed a sensation seeking measure. Hierarchical multiple regressions revealed that the amount of variability age accounted for in risk-taking (4.1%; β = −.22) was significantly reduced when sensation seeking was controlled for (0.8%; β = −.12). A Sobel test revealed that sensation seeking fully mediated the aforementioned relationship. Results suggest sensation seeking’s role as a mediator in more physiologically arousing risk-taking contexts (e.g., surfing). Discussion recommends investigating potential biologically and cognitively-rooted mediators and moderators of the age and risk-taking relationship. 相似文献

Using data from the first three waves (Grades 5, 6, and 7) of the 4-H Study of Positive Youth Development, this study assessed if being a bully or being a victim accounts for an adolescent's academic competence, if selected contextual and individual variables impact an adolescent's academic competence, and if such impact differs in relation to an adolescent's bullying status. The results of random coefficient hierarchical regression analyses indicated that being a bully predicted lower grades across time, and that being a bully was more detrimental for girls than for boys. Being a bully and being a victim negatively predicted self-perceived academic competence, but these predictive effects did not change over time or differ by sex. Teacher support positively predicted grades and greater parent support and teacher support independently predicted higher self-perceive academic competence. Greater educational expectations and school engagement independently predicted higher self-reported grades, while these two predictors positively interacted in explaining self-perceived academic competence. Unexpectedly, peer support negatively predicted self-reported grades for victims, and negatively predicted self-perceived academic competence for bullies. We discuss the importance of addressing the issue of academic competence in bullying interventions, as well as the utility of capitalizing on developmental assets in promoting academic competence among adolescents who bully and who are bullied. 相似文献

How to get “kissably close”: Examining how advertisers appeal to consumers’ sexual needs and desires 总被引:1,自引:0,他引:1
This paper explores the nature of sexual appelas—sex-related promises or benefits—in mainstream advertising by describing
types of sex appeals and findings from a sex-benefit content analysis. Overall, our findings reveal that sex is used to appeal
to women and men, although a higher proportion of sexual ads appear in men’s (12%) compared to women’s magazines (6%). In
addition, a variety of sex appeals are directed toward women (attractiveness, behavior, esteem), whereas most appeals directed
toward men emphasize more and better sex. Last, male-only images are relatively absent in sexual ads compared to female-only
(45%) and couples (47%) images. These findings, observations, and directions for future research are discussed. 相似文献
