The present study examined the association between theory of mind and indirect versus physical aggression, as well as the potential moderating role of prosocial behavior in this context. Participants were 399 twins and singletons drawn from two longitudinal studies in Canada. At five years of age, children completed a theory of mind task and a receptive vocabulary task. A year later, teachers evaluated children's indirect and physical aggression and prosocial behavior. Indirect aggression was significantly and positively associated with theory of mind skills, but only in children with average or low levels of prosocial behavior. Physical aggression was negatively associated with prosocial behavior but not with theory of mind. Each analysis included gender, receptive vocabulary, and the respective other subtype of aggression as control variables. These results did not differ between girls and boys or between twins and singletons. Theoretical and clinical implications of these findings are discussed.  相似文献

Recently, researchers have investigated the different structural forms of young children's nonsocial play behaviors. The primary goal of this research was to develop and validate the Preschool Play Behavior Scale (PPBS) , a teacher rating scale designed to assess the multiple forms of young children's solitary behaviors. In this regard, two studies were conducted. In Study 1, 39 preschool children were observed, and their social and nonsocial behaviors recorded over a three month period. Teachers then completed the PPB S. Results supported the construct validity of the PPBS ; teacher-rated and observed nonsocial and social behaviors were significantly associated in predicted ways. In Study 2, parental (e.g., demographic, child temperament) and teacher (e.g., PPBS , child behavior problems) ratings were collected for 337 preschoolers. Results established the psychometric properties of the PPBS (e.g., inter-rater reliability, factor structure, internal consistency, and convergent validity).  相似文献

The Monte Carlo (MC) simulation approach is traditionally used in food safety risk assessment to study quantitative microbial risk assessment (QMRA) models. When experimental data are available, performing Bayesian inference is a good alternative approach that allows backward calculation in a stochastic QMRA model to update the experts’ knowledge about the microbial dynamics of a given food‐borne pathogen. In this article, we propose a complex example where Bayesian inference is applied to a high‐dimensional second‐order QMRA model. The case study is a farm‐to‐fork QMRA model considering genetic diversity of Bacillus cereus in a cooked, pasteurized, and chilled courgette purée. Experimental data are Bacillus cereus concentrations measured in packages of courgette purées stored at different time‐temperature profiles after pasteurization. To perform a Bayesian inference, we first built an augmented Bayesian network by linking a second‐order QMRA model to the available contamination data. We then ran a Markov chain Monte Carlo (MCMC) algorithm to update all the unknown concentrations and unknown quantities of the augmented model. About 25% of the prior beliefs are strongly updated, leading to a reduction in uncertainty. Some updates interestingly question the QMRA model.  相似文献

A dynamic coupled modelling is investigated to take temperature into account in the individual energy consumption forecasting. The objective is both to avoid the inherent complexity of exhaustive SARIMAX models and to take advantage of the usual linear relation between energy consumption and temperature for thermosensitive customers. We first recall some issues related to individual load curves forecasting. Then, we propose and study the properties of a dynamic coupled modelling taking temperature into account as an exogenous contribution and its application to the intraday prediction of energy consumption. Finally, these theoretical results are illustrated on a real individual load curve. The authors discuss the relevance of such an approach and anticipate that it could form a substantial alternative to the commonly used methods for energy consumption forecasting of individual customers.  相似文献

We examined the potential role of three mediators—sexual self-esteem, sexual anxiety, and sexual assertiveness—of the association between romantic attachment insecurities (anxiety and avoidance) and two aspects of women's sexual functioning: sexual function and sexual satisfaction. A sample of 556 women aged 18 to 30 agreed to complete an online series of validated questionnaires assessing attachment insecurities and several aspects of sexual functioning. Lower sexual self-esteem and higher sexual anxiety mediated the associations between attachment anxiety and lower sexual function and satisfaction. Lower sexual self-esteem and higher sexual anxiety also partially mediated the links between attachment-related avoidance and the two sexual functioning variables. Sexual assertiveness, however, did not mediate these associations. A significant interaction between attachment anxiety and avoidance was also found to predict sexual satisfaction, with women high in avoidance and low in anxiety being the least satisfied. Results are discussed in terms of theoretical and clinical implications.  相似文献

ABSTRACT

This paper argues that we need to pay more theoretical attention to the ways in which migration industries come into being, how they produce a need for themselves within the management of migration processes. Using the example of the Global Mobility Industry (GMI), an industry that supports expatriate migration, the paper suggests that we can theorise migration industries as being part of the knowledge economy. It shows how the GMI is produced around the practices of knowing the successful expatriate which work to ‘calculate’ what expatriate migration should look like. In doing so, the paper shows the way in which the calculative practice of compartmentalisation, in producing knowledge about expatriate migration, produces a need for the GMI. This illustrates the importance of widening our understanding of the economy when researching the migration industries.  相似文献

Children of incarcerated parents are five to six times more likely to go to prison than their peers (Johnston, 1995). Yet, there is a lacuna in the literature that examines the effectiveness of interventions for children with an incarcerated family member. The purpose of the present study is to describe a solution-focused, mutual aid group intervention and to examine the effects of the group on the self-esteem of elementary-age Hispanic children of incarcerated parents when compared to a no-treatment comparison group. Implications for social work practice and research with this vulnerable population are addressed.  相似文献

This article conducts a critical analysis of the World Bank's current infrastructure strategy from a feminist perspective, arguing that failures to define gender and set meaningful targets and indicators have meant that gender has not been integrated into the implementation of infrastructure projects. It sets out three limitations to the Bank's approach to gender and infrastructure: lack of awareness of gender in the four sectors that comprise infrastructure; the Bank's narrow approach to gender equality and women's empowerment; and the failure of the Bank to mainstream gender in its current infrastructure strategy.  相似文献
