Emerging evidence suggests that abuse and neglect in childhood may play a role in subsequent development of obesity. One population group particularly at risk is children and young people living in out-of-home care (OOHC). Given this population is already a vulnerable group, identifying potential mechanisms by which childhood abuse and neglect increases risk for obesity is essential. A possible explanation is that problematic eating and food-related behaviours (i.e., emotional eating, compulsive eating, overeating, binge eating, stealing or hoarding food) might mediate the association between adverse childhood experiences and obesity. Hence, the overall goal of this paper was to provide a narrative review of eating and food-related difficulties for children in care and their possible association with unhealthy and excessive weight gain. This review revealed a shortage of existing empirical papers and signalled particular need for further examination of the mediating effects of problematic eating.  相似文献

It has been claimed that women experience fewer career opportunities than men do mainly because they are over-represented in ‘Dead-end Jobs’ (DEJs). Using Swedish panel data covering 1.1 million employees with the same employer in 1999 and 2003, measures of DEJ are empirically derived from analyses of wage mobility. The results indicate that women are over-represented in DEJs, especially in the public sector. The findings are interesting from (a) a methodological viewpoint, as it is indicated that the career opportunities associated with occupations can be indicated using one measure for both men and women, (b) the glass ceiling perspective, which arguably under-emphasizes gender inequality in relation to low positions, and (c) a class perspective, which basically ignores gender and sector in explaining career chances.

We use semi-parametric efficiency theory to derive a class of estimators for the state occupation probabilities of the continuous-time irreversible illness-death model. We consider both the setting with and without additional baseline information available, where we impose no specific functional form on the intensity functions of the model. We show that any estimator in the class is asymptotically linear under suitable assumptions about the estimators of the intensity functions. In particular, the assumptions are weak enough to allow the use of data-adaptive methods, which is important for making the identifying assumption of coarsening at random plausible in realistic settings. We suggest a flexible method for estimating the transition intensity functions of the illness-death model based on penalized Poisson regression. We apply this method to estimate the nuisance parameters of an illness-death model in a simulation study and a real-world application.  相似文献

The current study investigated the development of online reach control. Six- and 11-month-old infants reached for a toy while their hand position was tracked. The toy either remained stationary (baseline trials) or unexpectedly displaced left- or rightward during the reach (perturbation trials). To obtain a measure of online reach correction, we compared reaches in the perturbation trials to reaches in baseline trials using autoregression analysis. Infants of both age groups adjusted their reach trajectories in the direction of the displacement. Moreover, we divided the reaching movements into movement units, defined as the submovements of a reach between local minima in hand speed. Eleven-month-old infants adjusted their reach within the span of a single movement unit; corrections in 6-month-olds spanned multiple movement units. These results suggest that the reach control system has a rudimentary replanning capacity by 6 months of age, which, with age, further develops to a more sophisticated online control mechanism for ongoing reaches.  相似文献

The ways that parents respond to children's negative emotions shape the development of self-regulation across early childhood. The objective of this study was to examine child self-regulation in the context of intimate partner violence (IPV) exposure in a sample of Black, economically marginalized mothers and their young children (aged 3–5 years, N = 99). The study investigates the conditional effects of emotion socialization practices that (1) encourage expression of and problem-solving around negative affect (“supportive”), and (2) encourage suppression of affective displays (“suppressive”) on children's self-regulation. We found a significant association between higher child self-regulation and supportive parental reactions in the context of psychological IPV. We also found a significant association between higher child self-regulation and suppressive parental reactions in the context of psychological IPV. Our findings are consistent with prior research suggesting Black parents who teach varied strategies for emotional expression may promote children's adaptation in high-stress family environments. Macrosystem factors such as systemic racism and discrimination as well as the threat of family violence may shape how parents approach emotion socialization and the teaching of affective self-expression and self-regulation.  相似文献

‘Theory’ is a seminal term in sociology. Sociologists tend to ask that articles, chapters and monographs are ‘theoretical’, ‘develop theory’ or ‘make a theoretical contribution’. Yet, as demonstrated in Gabriel Abend’s 2008 article ‘The Meaning of ‘Theory’, it is generally unclear what sociologists mean when they talk about theory. Abend distinguishes seven different meanings sociologists tend to impute to ‘theory’ and argues that no single definition can usefully capture these substantively different meanings. Counter to Abend, we propose and defend a minimal and versatile theory of theory, which does capture the important common denominators in sociologists' various uses of the term theory. The major strengths of our proposal are that it enables informed and synthetic discussion and fosters reflexivity about differences and similarities between different types of theory. Our minimal theory of theory thus serves as an invitation to a broader conversation about theory in sociology.  相似文献

We explore the idea that prosocial behavior in experimental games is driven by social norms imported into the laboratory. Under this view, differences in behavior across subjects is driven by heterogeneity in sensitivity to social norms. We introduce an incentivized method of eliciting individual norm‐sensitivity, and we show how it relates to play in public goods, trust, dictator, and ultimatum games. We show how our observations can be rationalized in a stylized model of norm‐dependent preferences under reasonable assumptions about the nature of social norms. Then we directly elicit norms in these games to test the robustness of our interpretation.  相似文献
