An individual measure of relative survival   总被引:2,自引:0,他引:2  
Summary.  Relative survival techniques are used to compare survival experience in a study cohort with that expected if background population rates apply. The techniques are especially useful when cause-specific death information is not accurate or not available as they provide a measure of excess mortality in a group of patients with a certain disease. Whereas these methods are based on group comparisons, we present here a transformation approach which instead gives for each individual an outcome measure relative to the appropriate background population. The new outcome measure is easily interpreted and can be analysed by using standard survival analysis techniques. It provides additional information on relative survival and gives new options in regression analysis. For example, one can estimate the proportion of patients who survived longer than a given percentile of the respective general population or compare survival experience of individuals while accounting for the population differences. The regression models for the new outcome measure are different from existing models, thus providing new possibilities in analysing relative survival data. One distinctive feature of our approach is that we adjust for expected survival before modelling. The paper is motivated by a study into the survival of patients after acute myocardial infarction.  相似文献

Based on a comprehensive review of literature, the paper examines how ‘managerial work’ as a fluid analytical category has been approached methodologically, theoretically and empirically for more than 60 years. In particular, it highlights the existence of competing scholarly understandings regarding its nature, performance, meaning and politics. The authors suggest that subsequent empirical investigations have too often worked, methodologically and theoretically, to slot in, and thus effectively reduce, the term to a particular pre‐existing box, rather than exploring open‐endedly the what and how, but also the why of ‘managerial work’ as a distinct mode of situated ordering. Having represented the concept's past and present by identifying four distinct research approaches reflected in representative publications, the authors suggest that more attention should be devoted to a mode of analytical departure that promises to address directly the suggested shortcomings in the literature. Specifically, it is argued that much could be gained if contemporary notions of practice were brought into the study of managerial work. To this end, the authors outline the contours of a practice‐based approach as a sensitizing framework for understanding managerial work by highlighting the situated, relational, sociomaterial, meaning‐making and consequence‐oriented analytical foci the approach suggests, and suggesting a number of conjoint research questions, as well as acknowledging subsequent limitations.  相似文献

In Sweden, all parents of children aged 0–18 years are entitled to attend free parenting courses as part of a national strategy presented by the Government in 2009. This broad parental support welfare strategy is expected to fulfil the intentions of the UN Convention on the Rights of the Child. In this study, two parenting training manuals were analysed: the Canadian Connect program, based on attachment theory, and the Swedish ABC program, based on social learning theory. The results indicate that the manuals use strategies that can both hinder and support children's rights, regardless of rhetoric of children's best interests.  相似文献

This study (a) assesses whether employed young people, unemployed school-leavers, and unemployed young people who have working experience differ in their psychological well-being, that is stress, depression, and general feelings of happiness; (b) examines the effects of these three work conditions on development and structure of identity; and (c) investigates the effects of identity structure on psychological well-being. The favorability hypothesis of social comparison theory seems fit to explain the relation between identity structure and psychological well-being.  相似文献

We examined how perceived acculturation expectations from parents and school, and ethnic discrimination predicted early adolescents’ heritage and mainstream acculturation orientations at home (private domain) and in school (public domain) one year later. We surveyed 263 early adolescents of immigrant background in Germany (Mage = 10.44 years, 60% female). Multigroup path analyses revealed that perceived acculturation expectations and ethnic discrimination were more strongly related to adolescents’ private than public acculturation orientations. Parental heritage expectations were the strongest predictor of adolescents’ acculturation orientations. Boys were more susceptible than girls to ethnic discrimination and acculturation expectations in school, which affected their private and public acculturation orientations. Results highlight the importance of integrating domain‐specific and gendered experiences when analyzing adolescents’ acculturative development.  相似文献

The present study examined indirect over-time relations between parenting and adolescent sexuality through global self-esteem. Three waves of online questionnaire data were collected among a community sample of 1,116 Dutch adolescents (M = 13.9 years at baseline). Participants rated the quality of their relationship with parents, their global self-esteem, and their experience with various sexual behaviors. Sexually experienced adolescents (n = 168) evaluated their sexual experiences using six emotions. Path model results showed that a higher-quality relationship with parents at T1 predicted higher levels of self-esteem at T2, which in turn predicted less experience with sexual behaviors and more positive sexual emotions at T3. The indirect over-time path from relationship quality through self-esteem to adolescents’ sexual emotions was significant; the indirect path to adolescents’ experience with sexual behaviors was not significant at the .05 level. No significant age or gender differences were found in the path models. The findings indicate that self-esteem plays an important role in adolescent sexuality and that parents can contribute to positive sexual experiences of adolescents indirectly—through the enhancement of self-esteem—by fostering a high-quality relationship with their children. Implications for theory, future research, and strategies to promote healthy and positive youth sexuality are discussed.  相似文献

In this study we investigated longitudinal associations among parenting, children's temperamental negative affectivity, and internalizing and externalizing behavior. Second, we tested whether findings confirmed the diathesis‐stress model or differential susceptibility theory when conducting stringent interaction tests. The sample included 129 children and their families. Parenting quality (age 5) was measured by parent–child interaction observations. Parents evaluated child negative affectivity (age 7) and teachers reported on problem behavior (age 12). Multiple regression analyses revealed an interaction effect of negative affectivity and parenting on externalizing behavior. Visual inspection suggested ‘for better and for worse’ effects of parenting for children with negative affectivity. However, more stringent tests failed to show convincing evidence for differential susceptibility theory. For internalizing behavior, negative affectivity may render children vulnerable regardless of parenting. Our results point at the importance of further testing interaction effects to distinguish between differential susceptibility theory and the diathesis‐stress model.  相似文献

By exploiting the unique social and economic differences between East and West Germany, the authors investigated how macro‐level opportunities interact with couple‐level decision making to explain gender differences in the determinants and economic outcomes of household migration. By incorporating regional socioeconomic conditions into household bargaining theory, 4 hypotheses for each region were derived. The hypotheses were tested using cross‐classified multilevel regressions and the German Socio‐Economic Panel (1992–2012) combined with regional economic indicators. First, gender‐specific determinants of couples' West–West (i.e., within West Germany) and East‐to‐West migration were analyzed; second, subsequent economic consequences were investigated by comparing couples with singles. The results confirm that gender differences in macro‐conditions can impose decision logics that seemingly contradict the initial power relation within couples. Despite more traditional gender arrangements in West Germany, well‐educated partnered women earn significant absolute and relative income gains from migration; their egalitarian East German counterparts suffer significant losses compared with single women and East German men.  相似文献

In Sweden, children’s health and development are promoted through Primary Child Health Care (PCHC) visits. The children participate in these visits from their own perspective through bodily and verbal expressions. This study explores four‐year‐old children’s expressions when they as actors take part in a PCHC situation. The conceptualisation of the children’s expressions reveals various actions that exhibit their affirmative and delaying negotiation strategies to influence and deal with these situations. For PCHC nurses, these findings may encourage to view children as negotiating participants and inspire to sensitivity when inviting children and guiding them through health visits. © 2011 The Author(s).

It is unclear whether infants differentially process emotional faces in the brain at 5 months of age. Contradictory findings of previous research indicate that additional factors play a role in this process. The current study investigated whether five-month-old infants show differential brain activity between emotional faces. Furthermore, we explored the relation between emotional face processing and (I) stimulus characteristics, specifically the spatial frequency content, and (II) parent, child, and dyadic qualities of interaction characteristics. Face-sensitive components (i.e., N290, P400, Nc) in response to neutral and fearful faces that contained only lower or higher spatial frequencies were assessed. Quality of parent–child interaction was assessed with the Manchester Assessment of Caregiver Infant Interaction (MACI). The results show that, as a full group, none of the components differed between emotional expressions. However, when splitting the group based on median MACI scores, infants who showed high quality of interaction (i.e., more attentiveness to caregiver, positive and negative affect, and liveliness) processed emotions differently, whereas infants who showed low quality did not. These results indicate that a sub-group of infants show differential emotional face processing at 5 months of age, which seem to relate to quality of their behavior during the parent–child interaction.  相似文献
