This article draws upon data from an indepth ethnographic study of five- and six-year-old children in an English multi-ethnic, inner city primary school. It focuses on the significance of ‘race’ within young girls’ peer group relations and the ways in which the social dynamics that underlie those relations provide the context for understanding the particular nature and form that racism takes among the girls. This is done through a focus on the experiences of South Asian girls within the group. Within this, the article has two main aims. First, it aims to contribute to the literature within the sociology of education by extending the existing research focus on racism within teacher/pupil interactions to include an understanding of racism as it manifests itself among the children’s peer-group relations. Second, in adapting and applying Pierre Boudieu’s concepts of capital and field, the article also offers a contribution to the literature within the sociology of ‘race’ and ethnicity by suggesting one potentially fruitful way in which racism can be understood within specific social contexts.

It is well known that millimetre waves can pass through clothing. In short range applications such as in the scanning of people for security purposes, operating at W band can be an advantage. The size of the equipment is decreased when compared to operation at Ka band and the equipments have similar performance.
In this paper a W band mechanically scanned imager designed for imaging weapons and contraband hidden under clothing is discussed. This imager is based on a modified folded conical scan technology previously reported. In this design an additional optical element is added to give a Cassegrain configuration in image space. This increases the effective focal length and enables improved sampling of the image and provides more space for the receivers. This imager is constructed from low cost materials such as polystyrene, polythene and printed circuit board materials. The trade off between image spatial resolution and thermal sensitivity is discussed.
