Estimating Particle Shape and Orientation Using Volume Tensors

We develop statistical procedures for estimating shape and orientation of arbitrary three‐dimensional particles. We focus on the case where particles cannot be observed directly, but only via sections. Volume tensors are used for describing particle shape and orientation, and we derive stereological estimators of the tensors. These estimators are combined to provide consistent estimators of the moments of the so‐called particle cover density. The covariance structure associated with the particle cover density depends on the orientation and shape of the particles. For instance, if the distribution of the typical particle is invariant under rotations, then the covariance matrix is proportional to the identity matrix. We develop a non‐parametric test for such isotropy. A flexible Lévy‐based particle model is proposed, which may be analysed using a generalized method of moments in which the volume tensors enter. The developed methods are used to study the cell organization in the human brain cortex.     

Use of unopposed systemic estrogen therapy in non-hysterectomized women: a population-based study in the UK

A population study of 28 general practices in Oxfordshire, UK found that 0.028% of 17,712 non-hysterectomized women aged 45-60 years were using systemic unopposed estrogen. This is significantly lower than that reported in the Million Women Study.     

Broken Interaction Rituals,Struggles for Membership,and Violence among Young Children in Two Danish Schools

Children's conflicts, understood as disagreements involving negative emotional energy, constitute a particularly intense type of social interaction. In this paper, we show that children's conflictual interactions in school differ with regard to interactional dynamics and levels of confrontational tension, which together potentially lead to violence. We discuss how these differences relate to issues of inclusion and exclusion, to levels of interactional resources, and to neighborhood differences. Our conclusions are based on analysis of fieldwork data on children aged five to eight in two Danish schools. The analysis applies Goffman's and Collins's perspectives on interaction rituals and violence and the concept of emotional capital based on Bourdieu's theory of practice.     

Gender Stereotypes and the Reshaping of Stigma in Rehabilitative Eldercare

Rehabilitation policies are becoming increasingly popular in eldercare as a means to ensure dignity and reduce costs. This paper examines the implications of rehabilitation within Danish homecare work, a type of work that is often stigmatized due to its associations with low‐status ‘dirty’ body work in old people's homes. The paper combines two research traditions: studies of dirty work and studies of body work. It draws on observations and focus groups in Denmark to explore how the introduction of rehabilitation changes the work of care workers, and how such changes are associated with a potential reshaping of stigma. In contrast to previous research, this paper shows that although rehabilitation was partly introduced to reduce stigma of this type of work, the practice of rehabilitation paradoxically reinforces the stigma that it attempts to manage. Thus, the analysis helps to improve our understanding of the ambiguous and varying ways rehabilitative eldercare reshapes and reinforces stigma and gender stereotypes among women who do ‘dirty’ body work.     

Urban pram strolling: a mobilities design perspective

This paper explores a neglected mode of mobility through an ethnographic study of pram strollers in Copenhagen. I illustrate the analytic advantages of mobilities design thinking to explore how pram strolling is shaped by material designs and experienced through affective atmospheres, embodied practices and social encounters. In so doing, the pram is seen as a significant, yet largely overlooked, designed artifact that affords urban mobility. In the creative vein of mobilities design, the paper experiments with a new style of visual ethnography, surface ethnography, to help unravel the affordances of surfaces. In this process, I relate pram strolling to questions of urban accessibility issues, and more generally, reflect on the future applications and potentials of mobilities design thinking.
