The relations between the Norwegian Child Welfare Services (CWS) and various migrant groups are notably strained. Numerous media accounts and a growing body of research reveal that many migrants to Norway fear the CWS. By combining quantitative and qualitative analyses of media accounts, this paper addresses the historical evolvement of such strained relations in Norway. Previous research has neglected this aspect. Findings show that migration issues related to the CWS have been topics of public debate in Norway for three decades, with foster care being a particularly intractable concern. With the onset of the decade beginning in 2010, however, matters have intensified and taken on transnational dimensions. In the discussion of our findings, we emphasize in particular how digital and social media have contributed to the recent changes. 相似文献

To what extent substitute long term care modifies intergenerational transmission of substance abuse has rarely been investigated. Using register data, we followed a national cohort born 1973–1985 consisting of 1012 national adoptees, 2408 former children from long term foster care, 348/846 environmental siblings of adoptees/foster children, and 952,935 majority population peers, from their 15th birthday to age 27–35. Using Cox regression, we calculated hazard ratios (HR) for hospital care and criminality associated with illicit drug/alcohol abuse, with adjustments for socio-demographic indicators of caring families, and substance abuse in caring and birth parents. 相似文献

This study investigated the moderating role of intrinsic motivation on the relationship between trainee programme reactions and work performance among trainees enrolled in formal trainee programmes. The results from a cross-sectional survey among 114 trainees representing three Norwegian service organizations showed that the relationships between perception of the trainee programme and facets of self-reported work performance were positive only for trainees low in intrinsic motivation. Implications for practice and directions for future research are discussed. 相似文献

It is not unusual for old data to be used in epidemiological studies. Recently developed instruments for measuring work-related stress did not exist when the data collection was carried out. Therefore, approximate questions are sometimes used. An apparent problem is the lack of validation of proxy questions. The aim of this study was to compare the original questions for measuring Effort-Reward Imbalance (ERI) with approximate questions. The study population corresponded with a subgroup in the WOLF-n (WOrk, Lipids, Fibrinogen–north) cohort study of cardiovascular risk in a working population in the north of Sweden: 655 men and 178 women. The agreement in exposure between the original and the approximate ERI single questions was relatively low throughout, whereas the correlation between the ERI subscales and the ERI ratios was reasonable. The latter agreement between the original and the approximate ERI ratio indicates that the approximate measures might have been useful in the past. Yet, whenever possible the implementation of the original questionnaire in study protocols is recommended since a complete measurement of ERI might help to further improve the internal consistency and the predictive validity of this exposure to effort-reward imbalance. 相似文献

Recent work has shown that the Lasso-based regularization is very useful for estimating the high-dimensional inverse covariance matrix. A particularly useful scheme is based on penalizing the ?1 norm of the off-diagonal elements to encourage sparsity. We embed this type of regularization into high-dimensional classification. A two-stage estimation procedure is proposed which first recovers structural zeros of the inverse covariance matrix and then enforces block sparsity by moving non-zeros closer to the main diagonal. We show that the block-diagonal approximation of the inverse covariance matrix leads to an additive classifier, and demonstrate that accounting for the structure can yield better performance accuracy. Effect of the block size on classification is explored, and a class of asymptotically equivalent structure approximations in a high-dimensional setting is specified. We suggest a variable selection at the block level and investigate properties of this procedure in growing dimension asymptotics. We present a consistency result on the feature selection procedure, establish asymptotic lower an upper bounds for the fraction of separative blocks and specify constraints under which the reliable classification with block-wise feature selection can be performed. The relevance and benefits of the proposed approach are illustrated on both simulated and real data. 相似文献

This article explores gender differences in political communication among blogging politicians. The article sets out to explore two baseline questions: (1) Are distinct gendered ‘blogstyles’ to be found among political representatives? and (2) How do gender and gendered blogstyles interplay and affect the impact of political blogs? The empirical study draws on a survey targeting blogging politicians in Sweden (N?=?523). The analysis identifies substantial differences in how female and male politicians communicate in the blogosphere as well as the outcomes in terms of feedback and impact. Female politicians, to a greater degree than their male counterparts, utilize blogging for the purpose of fostering a stronger connection with their readers as well as to enquire about ideas and policy perspectives. This strategy seems to be successful for fostering qualitative feedback from readers; yet, female bloggers have far less impact than their male colleges. We discuss two potential understandings of these results: relating to gender stereotypes and the network power structure of the blogosphere. 相似文献
