Strategy-proof resolute social choice correspondences

We qualify a social choice correspondence as resolute when its set valued outcomes are interpreted as mutually compatible alternatives which are altogether chosen. We refer to such sets as “committees” and analyze the manipulability of resolute social choice correspondences which pick fixed size committees. When the domain of preferences over committees is unrestricted, the Gibbard–Satterthwaite theorem—naturally—applies. We show that in case we wish to “reasonably” relate preferences over committees to preferences over committee members, there is no domain restriction which allows escaping Gibbard–Satterthwaite type of impossibilities. We also consider a more general model where the range of the social choice rule is determined by imposing a lower and an upper bound on the cardinalities of the committees. The results are again of the Gibbard–Satterthwaite taste, though under more restrictive extension axioms.     

Self‐Employment as a Strategy for Dealing with the Competing Demands of Work and Family? The Importance of Family/Lifestyle Motives

In this paper, we test the argument that self‐employment may be a strategy for dealing with competing demands of work and family. We do this by comparing work–family conflict experienced by self‐employed and employed men and women. By examining to what extent the self‐employed versus regularly employed value time for themselves and their family — i.e., whether they are driven by family/lifestyle motives in their working life — we examine whether self‐employment can help reduce work–family conflict among those guided by family/lifestyle motives. Using data from a 2011 Swedish survey of 2483 self‐employed and 2642 regularly employed, the analyses indicate that experiences of work–family conflict differ between self‐employed and employees. Self‐employed men and women, especially those with employees, generally experience more work–family conflict than do employees. However, self‐employment can sometimes be a strategy for dealing with competing demands of work and family life. The presence of family/lifestyle motives generally decreases the probability of experiencing work–family conflict, particularly among self‐employed women with employees.     

Work–Life,Diversity and Intersectionality: A Critical Review and Research Agenda

Work–life issues have important implications at both organizational and individual levels. This paper provides a critical review of the work–life literature from 1990 onwards through the lens of diversity, with a particular focus on disparities of power induced by methodological and conceptual framings of work and life. The review seeks to answer the following questions: What are the gaps and omissions in the work–life research? How may they be overcome? To answer these questions, the review scrutinizes blind spots in the treatment of life, diversity and power in work–life research in both positivist and critical scholarship. In order to transcend the blind spots in positivist and critical work–life research, the review argues the case for an intersectional approach which captures the changing realities of family and workforce through the lens of diversity and intersectionality. The theoretical contribution is threefold: first, the review demonstrates that contemporary framing of life in the work–life literature should be expanded to cover aspects of life beyond domestic life. Second, the review explains why and how other strands of diversity than gender also manifest as salient causes of difference in experiences of the work–life interface. Third, the review reveals that social and historical context has more explanatory power in work–life dynamics than the micro‐individual level of explanations. Work–life literature should capture the dynamism in these contexts. The paper also provides a set of useful recommendations to capture and operationalize methodological and theoretical changes required in the work–life literature.     

Children with disabilities in Swedish child welfare – a differentiating and disabling practice

ABSTRACT

Research shows that children with disabilities are victims of violence and abuse to a higher extent than other children and thus need support from social services. In Sweden, cooperation between two different social services units is required to support children with disabilities in socially vulnerable families. In this study, we have examined the intersection between children and disability in a Swedish social services context from the perspective of childhood studies and disability studies. The reasoning of the two units including the child perspective emerged during focus group interviews based on two vignettes. The results show two different rationalities, which has consequences for the disabled child. In spite of a social policy where the ‘best interests of the child’ are meant to prevail and disabilities are meant to be interpreted as barriers in society, children with disabilities seem to be reduced to individuals who are lacking in ability and competency and who are profoundly victimised by power structures that favour the adult perspective in social services.     

The quotient of two correlated normal variables with applications

The purpose of this paper is to present new results on the distribution of the quotient of two correlated normal variables and its use to solve many outstanding problems in all fields of science, economics, industry, commerce, education, and medicine. The results are relatively simple and may encourage one to use the exact distribution of the quotient. Examples in medicine, economics and industry will illustrate the applications. Further, these results open a new vista for the solution not only of problems involving bivariate distributions but also multivariate distributions.     

Variability and Uncertainty in Swedish Exposure Factors for Use in Quantitative Exposure Assessments

Information of exposure factors used in quantitative risk assessments has previously been compiled and reported for U.S. and European populations. However, due to the advancement of science and knowledge, these reports are in continuous need of updating with new data. Equally important is the change over time of many exposure factors related to both physiological characteristics and human behavior. Body weight, skin surface, time use, and dietary habits are some of the most obvious examples covered here. A wealth of data is available from literature not primarily gathered for the purpose of risk assessment. Here we review a number of key exposure factors and compare these factors between northern Europe—here represented by Sweden—and the United States. Many previous compilations of exposure factor data focus on interindividual variability and variability between sexes and age groups, while uncertainty is mainly dealt with in a qualitative way. In this article variability is assessed along with uncertainty. As estimates of central tendency and interindividual variability, mean, standard deviation, skewness, kurtosis, and multiple percentiles were calculated, while uncertainty was characterized using 95% confidence intervals for these parameters. The presented statistics are appropriate for use in deterministic analyses using point estimates for each input parameter as well as in probabilistic assessments.     

New Results on the Small-Sample Properties of Some Robust Univariate Estimators of Location

This article compares eight estimators in terms of relative efficiencies with the univariate mean, some of which have not been compared previously. Four estimators, when testing hypotheses, are compared in terms of actual Type I errors. In terms of point estimation, the modified one-step M-estimator, one-step M-estimator, and rfch estimator are found to be the three best choices depending on the proportion of outliers. In terms of actual Type I errors, the modified one-step M estimator's and rfch estimator's level was between.045 and.055 in 5 out of 7 situations when real data were used in simulations.     

A generalized,multi-stage adjusted,latent class linear mixed model for testing genetic association

ABSTRACT

In this study, a Generalized, Multi-Stage Adjusted, Latent Class Linear Mixed Model is proposed for modeling the heterogeneous distributed phenotype and genetic information across the whole genome in the presence of both serial and familial correlations. Genome data were analyzed by applying the proposed model to Genetic Analysis Workshop (GAW) data, and the model results were compared to the results of standard models. Moreover, the potential of the model is discussed compared to simulated data. As a result of model comparisons, the information criteria and the genomic control parameter were found to be smaller. The results of a power analysis show that the proposed model is more powerful.
