Sustainability is usually defined as a requirement of each generation to manage its stocks of man-made and natural capital
such that the utility that it ensures itself can be shared by all future generations. Here we extend this definition to the
case where capital management does not have deterministic consequences. A characterization is offered where the sustainability
of one generation's behavior can be determined by comparing its utility with the utility of the succeeding generation, provided
that the latter behaves in a sustainable manner. The properties of the definition are investigated and illustrated.

Securing collective action in the field of asylum regulation is high on the European political agenda. In this article, we look at one country's partial pullback from the regional cooperation during the high influx of asylum seekers in 2015. We use Norway as a case to analyse the challenges to common European asylum regulations and the drivers of a region-wide tendency of what we call renationalisation. Against this background, we seek to contribute to the discussion on the dynamics of Europeanisation and the future of the Common European Asylum System. While the Europeanisation of migration policies has been well covered in the literature, tendencies of renationalisation have been less so. To contribute to the knowledge base, we create a typology of the drivers of renationalisation. These drivers include necessary political and institutional preconditions, resource limitations, triggers, expectations and aspects of time. 相似文献

This study aimed to evaluate the effectiveness of the International Child Development Programme (ICDP), a group-based parenting programme used internationally and implemented nationally in Norway. We used a cluster randomized controlled trial in which 81 groups were randomly assigned to either the intervention or waitlist control condition after the baseline data collection. A total of 590 parents completed at least one of three questionnaires (administrated before and after ICDP and 4 months after completing the intervention). Primary outcomes included parental self-efficacy, parental emotion sensitivity and positive involvement with their child. Secondary outcomes included parents' perceptions of their relationship with the child, child-rearing conflicts and the child's psychosocial health. We found significant effects favouring the intervention arm following the intervention and at follow-up on two primary outcomes (parental self-efficacy and emotion sensitivity). For the secondary outcomes, we found a significant reduction in child-rearing conflict at the 4-month follow-up, increased closeness to the child, reduced child internalizing difficulties and increased prosocial behaviour immediately following the intervention. However, ICDP seems to have limited effects on parent-reported changes in children. We conclude that ICDP as a universal preventive programme offered to parents in groups can be effective in strengthening parental self-efficacy and improving parental emotion sensitivity. 相似文献
