A robust procedure for testing the equality of mean vectors of two bivariate populations with unequal covariance matrices

A robust test is developed for testing equality of the mean vectors of two bivariate (multivariate) populations when the variance-covariance matrices are not necessarily equal. The test is an extension of the univariate robust test given by Tiku and Singh (1981).     

Exploration of associations between governance and economics and country level foot-and-mouth disease status by using Bayesian model averaging

Summary.  Using Bayesian model averaging, we quantify associations of governance and economic health with country level presence of foot-and-mouth disease (FMD) and estimate the probability of the presence of FMD in each country from 1997 to 2005. The Bayesian model averaging accounted for countries' previous FMD status and other possible confounders, as well as uncertainty about the 'true' model, and provided accurate predictions (90% specificity and 80% sensitivity). This model represents a novel approach to predicting FMD, and other conditions, on a global scale and in identifying important risk factors that can be applied to global policy and allocation of resources for disease control.     

Access to Higher Education for the Disabled Student: a building survey at the University of Liverpool

The problems associated with disabled students gaining access to higher education are complex and can be complicated further by difficulties encountered in the built environment of universities themselves. A survey of the built environment at the University of Liverpool was carried out using a group of occupational therapy undergraduate students. Students were able to learn about access audits and understand more fully the problems associated with access as part of their own studies. Results were recorded using a computer database, which enabled dissemination of information via the university's managed PC network and Home pages on the internet. Discussion and debate centre on the dilemma between a freely accessible environment for all students and the constraints imposed by the present day built environment and economic climate. The need for effective strategies in collaboration with disabled students is also considered.     

Social work and law in a foster care/adoption program

The push toward permanency planning has led to a blurring of distinctions between foster care and adoption, and consequent emotional and legal entanglements. The program described here was designed to emphasize cooperation between social workers and lawyers to safeguard the rights of all parties, and the authors discuss the pitfalls of casework with both biological and foster parents.     

Having It All? Women in High Commitment Careers and Work–Life Balance in Norway

The question if, or how, women can 'have it all' — high commitment career, partner and children — is regularly debated in popular media internationally. Drawing on qualitative research, this article examines work–life balance (WLB) for women in high commitment careers as politicians and non‐executive directors on corporate boards in Norway. Norway is lauded as one of the most gender equal countries in the world and in theory at least it is therefore a highly enabling environment for women to combine career and family. The article considers the WLB challenges women politicians and directors encounter and what types of WLB support — national, workplace and household level — are important for them in order to mitigate the potential strain caused by work–family conflict. This article's contribution is in highlighting the competing and sometimes contradictory policies, practices and discourses at multiple levels that surround WLB and the gendered social expectations of women in Norway who apparently 'have it all'.     

A Proof of Bell's Inequality in Quantum Mechanics Using Causal interactions

We give a simple proof of Bell's inequality in quantum mechanics using theory from causal interaction, which, in conjunction with experiments, demonstrates that the local hidden variable assumption is false. The proof sheds light on relationships between the notion of causal interaction and interference between treatments.
