The explanatory value of two theories expounding the quality of life are compared and discussed. To make this comparison possible, it is necessary to distinguish between rather clear theoretical assumptions and avoid a mix of theories: the variance explained by comparisons (multiple discrepancies) is compared with the variance explained by resource. Data obtained from the Vienna Student Survey (n=350) are presented. Although multiple-discrepancies theory (MDT) does explain far more variance than the resource approach, critical comments and proposals complete the study.  相似文献

This study (1) assessed whether parent health mediated associations between exposures to the 2010 BP Deepwater Horizon oil spill (BP-DHOS) and child health, and whether child health mediated associations between BP-DHOS exposures and parent health; and (2) assessed bidirectional longitudinal associations between parent health and child health following the BP-DHOS. The study used three waves of panel data (2014, 2016, and 2018) from South Louisiana communities highly impacted by the BP-DHOS. Parents with children (aged 4–18 at the time of the interview) were interviewed based on a probability sample of households. Focal measures included economic and physical BP-DHOS exposures, self-reported parent health, and parent-reported child health. Health measures were gathered at three time points. The analyses included mediation analysis and estimating and comparing effect sizes of longitudinal cross-lagged effects between parent health and child health. Results showed that parent health partly mediated associations between BP-DHOS exposures and child health, and that child health partly mediated associations between BP-DHOS exposures and parent health. Paths from prior waves of parent health to subsequent waves of child health were positive and statistically significant as were paths from prior waves of child health to subsequent waves of parent health. The differences in size of the child-to-parent health effects and the parent-to-child health effects were not statistically significant. This study’s results extend evidence for the post-disaster effect of parent health on child health and the effects of child health on parent health. These findings support the contention that harm to the health of one’s family member following disasters operates as a form of resource loss deleterious to one’s health.

This study evaluated the impact of housing services among child welfare-involved families using observational data. Propensity score matching with data from the National Survey of Child and Adolescent Well-Being compared intact families (n = 183) who received housing services 12 months after initial investigation to nontreated families balanced on characteristics at the time of investigation. Results suggested that general housing services failed, on average, to effectively address the needs of inadequately housed families.  相似文献

Objective: The objective of this study was to investigate whether misaligned or uncertain ambitions in adolescence influence the process of socioeconomic attainment. Methods: Using 34 years of longitudinal data from the British Cohort Study (BCS70), we considered whether youth with (1) misaligned ambitions (i.e., those who either over- or underestimate the level of education required for their desired occupation), (2) both low occupational aspirations and educational expectations (low-aligned ambitions), and (3) uncertainty with regard to their future occupations (uncertain ambitions) at age 16 experienced more unemployment spells, lower educational attainment, and lower hourly wages in adulthood compared to youth with high occupational aspirations and educational expectations (high-aligned ambitions). Results: Youth who hold misaligned or uncertain aspirations show long-term deficits in employment stability and educational attainment, which in turn leads to lower wage attainments at age 34. Conclusion: Misaligned and uncertain ambitions in adolescence compromise the construction of life paths and the realization of long-term educational and occupational goals.  相似文献

The origins of social insurance in industrialized and developing countries are discussed. In recent years social insurance programmes in many developing countries have come under sharp attack. Major issues have been raised with regard to how these programmes are operating, especially with regard to problems of inadequate coverage, adequacy and equity, shortfalls in financing, and administrative mismanagement. In addition to discussing these problem areas, the article reviews the major social insurance options: the family, social assistance, employer sponsored pensions, and savings plans encouraged or operated by governments.  相似文献

Based on data from 2091 call centre representatives working in 85 call centres in the UK, central assumptions of affective events theory (AET) are tested. AET predicts that specific features of work (e.g. autonomy) have an impact on the arousal of emotions and moods at work that, in turn, co‐determine job satisfaction of employees. AET further proposes that job satisfaction is an evaluative judgement that mainly explains cognitive‐based behaviour, whereas emotions and moods better predict affective‐based behaviour. The results support these assumptions. A clear separation of key constructs (job satisfaction, positive and negative emotions) was possible. Moreover, correlations between several work features (e.g. supervisory support) and job satisfaction were, in part, mediated by work emotions, even when controlling for gender, age, call centre type (in‐house versus outsourced centres) and call centre size. Predictions regarding consequences of satisfaction and affect were partly corroborated as continuance commitment was more strongly related to job satisfaction than to positive emotions. In addition, affective commitment and health complaints were related to both emotions and job satisfaction to the same extent. Thus, AET is a fruitful framework for explaining why and how specific management strategies used for designing work features influence important organizational attitudes and well‐being of employees.  相似文献
