title: Magnetic annihilation and reconnection in two dimensions

authors: Watson, P.G.

subjects: MHD—plasmas

abstract: The problems of incompressible, planar, magnetic annihilation and reconnection are discussed. We first emphasize that steady-state reconnection solutions can be constructed from annihilation models involving harmonic velocity fields. We show, however, that the only harmonic velocity profile capable of supporting inviscid magnetic annihilation is the traditional stagnation point flow φ= −αxy. The implication is that further steady-state planar reconnection models derived from annihilation solutions are impossible. We go on to show that certain classes of nonharmonic stream functions allow reconnection solutions to be developed, once the constraint of time independence is relaxed. In particular, we construct an exact reconnection model based on cellular inflows into a periodic assemblage of magnetic X-points.

title: Strangers in their own land: friendship issues when children have cancer

authors: Fraser, Deborah

subjects: child cancer

abstract: More children than ever before are surviving childhood cancer. While treatment protocols have improved, there is little consideration given to their ongoing educational needs, including their social needs for positive peer relationships and friendships. This qualitative study of 12 families included children from four to 15 years of age. Most of the children were attending primary school and half were still undergoing treatment. Interviews in family homes were undertaken with parents, children with cancer and their siblings. The results show that most of these children with cancer have special social relationship needs beyond the impact of absence from school. This article focuses specifically upon friendships and peer relationships which often change dramatically when a child has cancer. Such changes can place children with cancer at risk both academically and emotionally. Some suggestions for addressing this issue are explored.
