This study explores patterns of collaboration between Swedish professionals involved in the repatriation of unaccompanied asylum-seeking refugee children. A qualitative case study methodology was used. Semi-structured interviews were conducted with a total of 20 statutory social workers, social workers at care homes, police officers, Swedish Migration Board officers, and legal guardians. A thematic approach was used to analyse the data. The results showed low levels of collaboration among the professionals and the use of different strategies by the professionals to manage their work tasks. Patterns were found among the professionals: some tended to isolate themselves from interaction and acted on the basis of personal preference, and others tended to behave sensitively, withdraw, and become passive observers rather than active partners in the repatriation process. These behaviours made it difficult for the relevant professionals to employ dignity and efficiency in the repatriation of unaccompanied asylum-seeking refugee children.  相似文献

Abstract

In this article we study the relationship between principal component analysis and a multivariate dependency measure. It is shown, via simulated examples and real data, that the information provided by principal components is compatible with that obtained via the dependency measure δ. Furthermore, we show that in some instances in which principal component analysis fails to give reasonable results due to nonlinearity among the random variables, the dependency statistic δ still provides good results. Finally, we give some ideas about using the statistic δ in order to reduce the dimensionality of a given data set.  相似文献

The aims were to describe Swedish social work students' personality characteristics upon entry to their training and to analyze relationships between personality traits, mental health, and some sociodemographic variables. One hundred and twenty-one female social work students completed a sociodemographic form, the Temperament and Character Inventory, and the Symptom Checklist. They scored significantly higher on harm avoidance, reward dependence, and self-transcendence and reported more somatization, obsessive compulsive, and phobic-anxious symptoms, and less hostility, than Swedish individuals from the general population of the same age. Personality traits significantly predicted the various mental symptom scores. It is recommended to implement modules or training courses within social work training in Sweden that bring an improvement of self-directedness and cooperativeness character trait into focus.  相似文献

We propose a double-robust procedure for modeling the correlation matrix of a longitudinal dataset. It is based on an alternative Cholesky decomposition of the form Σ=DLL ? D where D is a diagonal matrix proportional to the square roots of the diagonal entries of Σ and L is a unit lower-triangular matrix determining solely the correlation matrix. The first robustness is with respect to model misspecification for the innovation variances in D, and the second is robustness to outliers in the data. The latter is handled using heavy-tailed multivariate t-distributions with unknown degrees of freedom. We develop a Fisher scoring algorithm for computing the maximum likelihood estimator of the parameters when the nonredundant and unconstrained entries of (L,D) are modeled parsimoniously using covariates. We compare our results with those based on the modified Cholesky decomposition of the form LD 2 L ? using simulations and a real dataset.  相似文献

Pregnant CD-1 mice were exposed to cortisone acetate at doses ranging from 20 to 100 mg/kg/ day on days 10-13 by oral and intramuscular routes. Multiple replicate assays were conducted under identical conditions to assess the reproducibility of the dose–response curve for cleft palate. The data were fitted to the probit, logistic, multistage or Armitage-Doll, and Weibull dose-response model separately for each route of exposure. The curves were then tested for parallel slopes (probit and logistic models) or coincidence of model parameters (multistage and Weibull models). The 19 replicate experiments had a wide range of slope estimates, wider for the oral than for the intramuscular experiments. For all models and both routes of exposure the null hypothesis of equality of slopes was rejected at a significant level of p < 0.001. For the intramuscular group of replicates, rejection of slope equality could in part be explained by not maintaining a standard dosing regime. The rejection of equivalence of dose-response curves from replicate studies showed that it is difficult to reproduce dose-response data of a single study within the limits defined by the dose-response model. This has important consequences for quantitative risk assessment, public health measures, or development of mechanistic theories which are typically based on a single animal bioassay.  相似文献

Using the Integrated Mission System of the Equal Employment Opportunity Commission, the employment discrimination experience of Americans with diabetes is documented. Researchers compare and contrast the key dimensions of workplace discrimination involving Americans with diabetes and persons with other physical, sensory, and neurological impairments. Specifically, the researchers examine demographic characteristics of the charging parties; the industry designation, location, and size of employers against whom complaints are filed; the nature of discrimination (i.e., type of adverse action) alleged to occur; and the legal outcome or resolution of these complaints. Findings indicate that persons with diabetes were more likely to encounter discrimination involving discharge, constructive discharge, discipline and suspension - all job retention issues. Persons with diabetes were less likely to encounter discrimination involving hiring, reasonable accommodation, non-pension benefits, and layoff. They were also more likely to encounter discrimination when they were older or from specific ethnic backgrounds, or when they worked for small employers or in the Southern United States. Implications for policy and advocacy are addressed.  相似文献

Given an undirected graph with a source node s and a sink node t. The anti-risk path problem is defined as the problem of finding a path between node s to node t with the least risk under the assumption that at most one edge of each path may be blocked. Xiao et al. (J Comb Optim 17:235–246, 2009) defined the problem and presented an \(O(mn+n^2 \log n)\) time algorithm to find an anti-risk path, where n and m are the number of nodes and edges, respectively. Recently, Mahadeokar and Saxena (J Comb Optim 27:798–807, 2014) solved the problem in \(O(m+n \log n)\) time. In this paper, first, a new version of the anti-risk path (called contra-risk path) is defined, which is more effective than an anti-risk path in many networks. Then, an algorithm to find a contra-risk path is presented, which runs in \(O(m+n \log n)\) time.  相似文献

In this paper, we discuss some stochastic comparisons for the sample median in a random sample from a normal distribution. Specifically, we establish that the sample median is stochastically farther than the sample mean to the population mean. To verify the result of comparison, we derive an upper bound for some distributional characteristics of the distance between the sample median and the population mean. The stochastic ordering considered here is the likelihood ratio order.  相似文献
