Understanding and negotiating identity: Children from cross-community families in public care in Northern Ireland.

In Northern Ireland, most research on the impact upon children of living through the 'troubles' and in a divided society has assumed that children are from either the Catholic or Protestant community. There has been very little researchwith children from cross-community families who have one parent from a Catholic background and one from a Protestant background. it is know, however, that these children are over-represented in the public care system in Northern Ireland. The study reported in this paper addresses this gap in knowledge by exploring the experiences and views of children from cross-community families who are in public care in northern Ireland. The study has key messages for the development of services for looked after children from cross-community families, if these are to be delivered in accordance with legislative duties in Northern Ireland and in an anti-sectarian manner.

The purification and characterization of phosphonopyruvate hydrolase, a novel carbon-phosphorus bond cleavage enzyme from Variovorax sp. Pal2.

Phosphonopyruvate hydrolase, a novel bacterial carbon-phosphorus bond cleavage enzyme, was purified to homogeneity by a series of chromatographic steps from cell extracts of a newly isolated environmental strain of Variovorax sp. Pal2. The enzyme was inducible in the presence of phosphonoalanine or phosphonopyruvate; unusually, its expression was independent of the phosphate status of the cell. The native enzyme had a molecular mass of 63 kDa with a subunit mass of 31.2 kDa. Activity of purified phosphonopyruvate hydrolase was Co2+-dependent and showed a pH optimum of 6.7–7.0. The enzyme had a Km of 0.53 mM for its sole substrate, phosphonopyruvate, and was inhibited by the analogues phosphonoformic acid, 3-phosphonopropionic acid, and hydroxymethylphosphonic acid. The nucleotide sequence of the phosphonopyruvate hydrolase structural gene indicated that it is a member of the phosphoenolpyruvate phosphomutase/isocitrate lyase superfamily with 41% identity at the amino acid level to the carbon-to-phosphorus bond-forming enzyme phosphoenolpyruvate phosphomutase from Tetrahymena pyriformis. Thus its apparently ancient evolutionary origins differ from those of each of the two carbon-phosphorus hydrolases that have been reported previously; phosphonoacetaldehyde hydrolase is a member of the haloacetate dehalogenase family, whereas phosphonoacetate hydrolase belongs to the alkaline phosphatase superfamily of zinc-dependent hydrolases. Phosphonopyruvate hydrolase is likely to be of considerable significance in global phosphorus cycling, because phosphonopyruvate is known to be a key intermediate in the formation of all naturally occurring compounds that contain the carbon-phosphorus bond.

Rambling in the Field of Modern Identity: Some Speculations on Irish Traditional Music

This article argues that Irish “traditional” music is modern in its form and history, and explores the ramifications of this thesis for understanding of the peculiarities of Irish modernity and identity. The article exhaustively surveys the historiography of Irish traditional music and uniquely interprets this literature in relation to competing conceptions of identity and modernity articulated by Taylor, Appiah and Žižek. It also interprets Irish traditional music in relation to conceptions of Irish modernity articulated in a wide range of disciplines within Irish studies. Reflecting on the author’s lifelong engagement with traditional music performance, the article argues that the resilience of traditional music within the broader culture is connected to the peculiar character of Irish modernity, and that it suffers from problems of aesthetic exhaustion shared by much modern art in the contemporary conjuncture.
