Experimental research suggests the differentiation of ‘nice’ and ‘nasty’ theory of mind (ToM). Over 5000 parents from the Twins Early Development Study reported on nice (e.g., being considerate) and nasty (e.g., blaming others) behaviours following their twins’ second, third, and fourth birthdays. Factor analyses yielded four factors and it was proposed that these related to prosocial behaviour necessitating ToM (Nice ToM), antisocial behaviour necessitating ToM (Nasty ToM), and prosocial and antisocial behaviour not necessitating ToM (Nice and Nasty). Interscale correlations, gender differences, and their relationship with language were consistent with this distinction. Both ToM scales showed moderate heritability and significant environmental influences (shared and nonshared). Bivariate analyses indicated somewhat distinct aetiological influences on Nice ToM versus Nasty ToM. However, further research is needed to confirm whether this distinction reflects interactions between ToM and temperament, or two underlying genetic and cognitively distinct ToM abilities. 相似文献

Leveraging historical data into the design and analysis of phase 2 randomized controlled trials can improve efficiency of drug development programs. Such approaches can reduce sample size without loss of power. Potential issues arise when the current control arm is inconsistent with historical data, which may lead to biased estimates of treatment efficacy, loss of power, or inflated type 1 error. Consideration as to how to borrow historical information is important, and in particular, adjustment for prognostic factors should be considered. This paper will illustrate two motivating case studies of oncology Bayesian augmented control (BAC) trials. In the first example, a glioblastoma study, an informative prior was used for the control arm hazard rate. Sample size savings were 15% to 20% by using a BAC design. In the second example, a pancreatic cancer study, a hierarchical model borrowing method was used, which enabled the extent of borrowing to be determined by consistency of observed study data with historical studies. Supporting Bayesian analyses also adjusted for prognostic factors. Incorporating historical data via Bayesian trial design can provide sample size savings, reduce study duration, and enable a more scientific approach to development of novel therapies by avoiding excess recruitment to a control arm. Various sensitivity analyses are necessary to interpret results. Current industry efforts for data transparency have meaningful implications for access to patient‐level historical data, which, while not critical, is helpful to adjust for potential imbalances in prognostic factors. 相似文献

Introducing continental European approaches to UK child welfare practice raises a problem of comparison: to what extent are the problems and issues similar to or different from one country compared to another. Social pedagogues trained in continental Europe and working in English residential care services often encountered the phrase ‘our young people are worse’ from their English colleagues, with the implication that the social pedagogic approach was not suitable for the client group. This paper examines two propositions: (1) that in the context of introducing the continental European approach of social pedagogy into children's residential care services in England, young people are ‘different’ in England compared to other European countries and (2) that the placement options and practices for young people living away from their birth parents in continental European countries differ from those in England. Using data from a five nation study of young people from public care backgrounds, the paper argues that while family backgrounds are remarkably similar there are marked differences in the child welfare systems that might account for the perception that young people in care are ‘worse’ in England. 相似文献

Much debate surrounds the issue of whether allowing candidates to listen to recordings twice is more desirable in language tests than offering just one opportunity. Using regression models, this study investigates, analyses and interconnects both item difficulty and stimulus length in relation to the frequency of stimulus presentation and its effect on test results. The study involved 1,266 eighth-grade learners with perceived A2/B1 level in English as a first foreign language. The final discussion seeks to offer explanations for the results that clearly indicate the advantages of listening once; likewise, potential implications for listening tests and classroom practice are raised. 相似文献

Using a social dilemma game, we study the cooperative behavior of individuals who reintegrate their group after being excluded by their peers. We manipulate the length of exclusion and whether this length is imposed exogenously or results from a vote. We show that people are willing to exclude the least cooperators and they punish more, and more severely, chronic defections. In return, a longer exclusion has a higher disciplining effect on cooperation after reintegration, but only when the length of exclusion is not chosen by group members. Its relative disciplining effect on cooperation after reintegration is smaller when the length of exclusion results from a vote. In this environment, a quicker reintegration also limits retaliation. The difference in the impact of long versus short exclusion on retaliation is larger when the length of exclusion is chosen by group members than when it is exogenous. Post-reintegration cooperation and forgiveness depend not only on the length of exclusion but also on the perceived intentions of others when they punish. (JEL C92, H41, D23) 相似文献
