Expected Mean Squares for Hierarchical Factorial Layouts with Population Imbalance

We introduce an analysis of variance usable for two-factor hierarchical models where observations are incompletely sampled from unbalanced populations of finite effects. Our new approach enables unbiased estimation of the variance components for this type of model and allows hypothesis testing to identify significant effects/sub-class effects. An explanation of how these results can be generalized to factorial layouts with more than two factors is given.     

The significance of place in middle childhood: qualitative research from Wales

The paper presents some key findings of qualitative research with older primary school children in Wales on their attachments to places and cultures. There is discussion of children's perspectives on the global, national and local arenas. We argue both that there are continuities with adult perspectives and that the children's views on place and identity need to be understood in the context of the social location of middle childhood. The study shows children making relatively little use of culturally-filled categories of local, national and global place-identifications. The differences they articulate are largely framed in terms of divisions between groups of people rather than in the characteristics of place, and generally related back to the self.     

The effect of shiftwork related fatigue on the family life of train operators: implications for safety and health professionals

Drawing upon an original research study about the effects of fatigue on train operators, the present article focuses upon family issues as having the most significant impact on the participants. Family support, for example, represents an important mechanism for managing and coping with fatigue. Family support comprises understanding of the physiological and emotional issues surrounding shiftwork and erratic work schedules. This article explores the impact of fatigue upon a variety of family and relational issues. This inquiry describes the impact of family on the broader employee view of managing fatigue that considers such comprehensive issues as perception of the work environment, emotional stability, personal control concerns and other positive attributes. These issues ultimately impact the health, productivity and performance of employees. Final discussion includes implications for workplace application of the research findings.
