Small sample distribution of the likelihood ratio test in the random effects model

In this paper we examine the small sample distribution of the likelihood ratio test in the random effects model which is often recommended for meta-analyses. We find that this distribution depends strongly on the true value of the heterogeneity parameter (between-study variance) of the model, and that the correct p-value may be quite different from its large sample approximation. We recommend that the dependence of the heterogeneity parameter be examined for the data at hand and suggest a (simulation) method for this. Our setup allows for explanatory variables on the study level (meta-regression) and we discuss other possible applications, too. Two data sets are analyzed and two simulation studies are performed for illustration.     

Optimal Designs for Binary Logistic Regression with a Qualitative Classifier with Independent Levels

Dose response studies arise in many medical applications. Often, such studies are considered within the framework of binary-response experiments such as success-failure. In such cases, popular choices for modeling the probability of response are logistic or probit models. Design optimality has been well studied for the logistic model with a continuous covariate. A natural extension of the logistic model is to consider the presence of a qualitative classifier. In this work, we explore D-, A-, and E-optimal designs in a two-parameter, binary logistic regression model after introducing a binary, qualitative classifier with independent levels.     

Functional logistic regression: a comparison of three methods

Functional logistic regression is becoming more popular as there are many situations where we are interested in the relation between functional covariates (as input) and a binary response (as output). Several approaches have been advocated, and this paper goes into detail about three of them: dimension reduction via functional principal component analysis, penalized functional regression, and wavelet expansions in combination with Least Absolute Shrinking and Selection Operator penalization. We discuss the performance of the three methods on simulated data and also apply the methods to data regarding lameness detection for horses. Emphasis is on classification performance, but we also discuss estimation of the unknown parameter function.     

Women's experiences of self-reporting health online prior to their first midwifery visit: A qualitative study

Background

Information and communication technologies are increasingly used in health care to meet demands of efficiency, safety and patient-centered care. At a large Danish regional hospital, women report their physical, mental health and personal needs prior to their first antenatal visit. Little is known about the process of self-reporting health, and how this information is managed during the client-professional meeting.

Reshaping boundaries: Family politics and GLBTQ resistance in urban Vietnam

Although Vietnamese society is currently undergoing significant changes with regards to the rights and perceptions of gay, lesbian, bisexual, transgender, and queer (GLBTQ) people, dominant socio-cultural norms related to gender, sexuality, and the importance of the patrilineal family regime continue to cast a shadow over the lives of GLBTQ in contemporary Vietnam. Based on ethnographic fieldwork conducted in the urban centers of Hanoi and Ho Chi Minh City, as well as legal documents and secondary sources, this article illustrates how dominant heteronormative socio-cultural norms have contributed to the political, legal, and social exclusion of same-sex sexualities through a process of outlawing, whereby GLBTQ have been systematically excluded from the rights of law. Drawing on qualitative interviews with gay men and lesbian women between the ages of 20 and 50, the article also highlights how this relation of domination has allowed for instances of GLBTQ resistance, through subversive opposition, strategies of avoidance, and the seeking out of new opportunities in urban spaces outside the dominant sociality. The article thus provides a qualitatively nuanced account of family politics and GLBTQ resistance in urban Vietnam at a significant socio-political historical juncture.     

Revitalizing social work education through global and critical awareness: examples from three Scandinavian schools of social work

ABSTRACT

Increasing globalisation, reorganisation of the Scandinavian welfare regimes and the awareness of increasing global roots of local social problems necessitated change in the curriculum of social work in three Scandinavian schools of social work in Denmark, Norway and Sweden. Recent global transformations, increasing global inequalities, increasing forced migration and the emergence of glocal social problems make the traditional education and methods of social work ineffective and in some cases harmful for people in need of social work intervention. This article examines the need to provide critical, global and multilevel perspectives in social work education in order to prepare social work students for the increasing social problems with global roots. The article, which is based on cross-national collaborations in social work education between three Scandinavian countries, addresses global and critical components in theoretical courses, professional training and field practice in the social work education of the countries in question. It is argued that social work education should move beyond the old division of classical and international/intercultural toward including global and critical perspectives in an integrative manner in all programs.     

On the Parameter Estimation of the Asymmetric Multivariate Laplace Distribution

This article examines a family of three-parameter multivariate Laplace distributions ML _p (a, μ, Σ) which is closed under constant shifts. Parameter vectors a and μ are called shift and shape parameter, respectively, positive definite p × p-matrix Σ is a scale parameter. The first three moments are derived and used for estimating the parameters. The behavior of the obtained estimates is explored in a simulation experiment.     

‘You Can Stand on Your Head and Still End Up with Lower Pay’: Gliding Segregation and Gendered Work Practices in Danish ‘Family‐friendly’ Workplaces

This article explores the process of gliding segregation in two Danish workplaces. We address the questions of how and why women and men at the same workplace, with the same levels of education, often end up doing different work tasks. Drawing on a gendered organization perspective and sense of entitlement theory we illustrate the processes whereby structural and cultural expectations place women in predictable and routine work, and men in more developmental work. We also show that the level of education makes a difference to women's sense of entitlement to developmental work, but that the discourse of family friendliness disadvantages women in the allocation of interesting and valued work tasks. The findings illustrate the resilience of gendered work practices and the importance of focusing on workplace interactions to explain this.
