Event history models, also known as hazard models, are commonly used in analyses of fertility. One drawback of event history models is that the conditional probabilities (hazards) estimated by event history models do not readily translate into summary measures, particularly for models of repeatable events, like childbirth. In this paper, we describe how to translate the results of discrete-time event history models of all births into well-known summary fertility measures: simulated age- and parity-specific fertility rates, parity progression ratios, and the total fertility rate. The method incorporates all birth intervals, but permits the hazard functions to vary across parities. It can also simulate values for groups defined by both fixed and time-varying covariates, such as marital or employment life histories. We demonstrate the method using an example from the National Survey of Family Growth and provide an accompanying data file and Stata program. 相似文献

Recent research into school readiness has highlighted the importance of not only children's cognitive and socio‐emotional skills, but also the degree to which they have family support in the home. The current study examines the association between social success upon school entry and teacher‐ratings of school readiness as assessed by the Brief Early Skills and Support Index (BESSI), controlling for language ability. Importantly, social success was assessed using a “child's‐eye view” with peer‐reported assessments of both social preference and reciprocated friendships. A total of 244 children (131 boys, Mage = 61 months, SD = 4.78 months) in their first year of formal schooling participated. Child school readiness was found to be important for social preference, with the association being more marked for boys versus girls. Family support was the only independent predictor of children's reciprocated friendships. The use of the BESSI, with its broad scope compared to other measures of school readiness, highlights the importance of focusing both on a child's cognitive and socio‐emotional skills at school entry and their family support when exploring the association of school readiness to children's social success at the transition to formal schooling. 相似文献

‘Speak roughly to your little boy’? Sex Differences in the Relations Between Parenting and Preschoolers’ Understanding of Mind 总被引:1,自引:0,他引:1
The present study explores relations between young children's understanding of mind and parental emotional expression and disciplinary style, along with gender differences in these relations. Participants were recruited from a study of 125 same-sex twin-pairs (58% female; group mean age 5 43 months, SD 5 1 month). Each child received a comprehensive set of theory-of-mind tasks, and was filmed at home for 20 minutes in dyadic interactions with the primary caregiver, who was also interviewed about disciplinary strategies. Ratings of discipline and positive and negative parental affect and control were made from direct observation, from the interview, and from the videoed interactions. Strong correlations were found between family SES, parenting measures, and child verbal IQ and theory-of-mind score. However, regression analyses showed that parental behaviours were significant predictors of children's theory-of-mind performance, even when sex, verbal IQ and family SES were taken into account. Sex differences in these relations were also identified; parental affect was especially salient for understanding of mind in girls, while discipline was more salient for boys. Taken together, these findings highlight the importance of individual differences in the proximal processes associated with early understanding of mind, and suggest that development in mental-state awareness is associated with distinct aspects of parenting for girls and boys. 相似文献

Peers and friends are perceived as important role models for the formation of children's attitudes and behaviours. A wealth of research has aimed to establish the contribution of peers and friends to children's developing eating behaviours, and their attitudes towards eating. This review describes and evaluates such research. Experimental research examining peer modelling of food consumption and liking is reviewed, and several individual child factors that are suggested to make children more or less receptive to peer and friend influences are discussed. The influence of children's perceptions of their peers’ and friends’ eating behaviours upon their own eating practices is also explored. The benefits of future longitudinal research to improve understanding of peer and friend influences on children's eating are emphasized. 相似文献

Across the UK recent policy developments have focused on improved information sharing and inter‐agency cooperation. Professional non‐reporting of child maltreatment concerns has been consistently highlighted as a problem in a range of countries and the research literature indicates that this can happen for a variety of reasons. Characteristics such as the type of abuse and the threshold of evidence available are key factors, as are concerns that reporting will damage the professional‐client relationship. Professional discipline can also impact on willingness to report, as can personal beliefs about abuse, attitudes towards child protection services and experiences of court processes. Research examining the role of organisational factors in information sharing and reporting emphasises the importance of training and there are some positive indications that training can increase professional awareness of reporting processes and requirements and help to increase knowledge of child abuse and its symptoms. Nonetheless, this is a complex issue and the need for training to go beyond simple awareness raising is recognised. In order to tackle non‐reporting in a meaningful way, childcare professionals need access to on‐going multidisciplinary training which is specifically tailored to address the range of different factors which impact on reporting attitudes and behaviours.

The study describes an evaluation of a 48‐week physical activity and nutritional education programme for overweight/obese school‐age children using quantitative and qualitative methods. The majority of participants were obese or severely obese when enrolled, and while some improvements in body mass index, self‐esteem and engagement in a range of physical activities were noted, difficulties in evaluating a complex community‐based intervention were highlighted. Children, parents and health professionals described a range of benefits from attending the programme but more intensive services are likely to be needed for the most seriously obese children and for those families resisting intervention. 相似文献
