This book offers new insights into the close relationship between political discourses and conflict resolution through critical analysis of the role of discursive change in a peace process.
Just as a peace process has many dimensions and stakeholders, so the discourses considered here come from a wide range of sources and actors. The book contains in-depth analyses of official discourses used to present the peace process, the discourses of political party leaders engaging (or otherwise) with it, the discourses of community-level activists responding to it, and the discourses of the media and the academy commenting on it. These discourses reflect varying levels of support for the peace process – from obstruction to promotion – and the role of language in moving across this spectrum according to issue and occasion. Common to all these analyses is the conviction that the language used by political protagonists and cultural stakeholders has a profound effect on progression towards peace.
Bringing together leading experts on Northern Ireland’s peace process from a range of academic disciplines, including political science, sociology, linguistics, history, geography, law, and peace studies, this book offers new insights into the discursive dynamics of violent political conflict and its resolution.

Hayes and Houston's positive review of Habermas's contribution to discourse in family group conferences (in this journal) has been challenged by Garrett. In this paper, one of the authors replies to Garrett but extends the analysis through a more considered, developed and detailed examination of Habermas's thoughts on power in social life. This leads to a conceptual framework that enables the participants in the conference to exercise power in a positive manner. In developing this earlier analysis, the paper also acknowledges Garrett's argument that Bourdieu helps us to understand the nature of constraining social structures in child protection. However, Bourdieu's ideas are subsequently challenged on the grounds that they lack a competent formulation on human agency - a faculty that Habermas cogently elucidates. This enlarged understanding of agency, it is argued, offers a theoretical resource that fits better with the ethos of emancipatory social work.

The discovery that the hypotensive sequela of envenomation by the South American viper, Bothrops jararaca, was mediated by peptides, represented a milestone in drug discovery research that led to the introduction of ACE inhibitors. These bradykinin-potentiating peptides (BPPs) have been found in the venoms of many species of viper and molecular cloning of biosynthetic precursors has revealed that each encodes several different BPPs in tandem with a single copy of a C-type natriuretic peptide (CNP) located at the C-terminus. Venoms of the African forest vipers (Atheris) have been poorly studied possibly because they do not represent a major danger to humans. However, initial studies have indicated that they contain some of the “classical” protein toxins of viper venoms and a novel class of peptide, the polyglycine/polyhistidine (pGpH) peptides. These peptides occur in several molecular forms with different numbers of repetitive glycine and histidine repeats. We have cloned the biosynthetic precursor of A. squamigera pGpH peptides from a venom-derived cDNA library and have confirmed that a single copy of CNP is located at the C-terminus and additionally that, like BPPs in other vipers, pGpH peptides are encoded in tandem within this single precursor. Solid phase peptide synthesis of pGpH peptides has proven to be extremely difficult but is progressing and acquisition of synthetic replicates of each peptide is a necessary prerequisite for systematic pharmacological characterisation as establishment of a biological function for these peptides remains elusive. pGpH peptides may prove to play a role as fundamental as that of the BPPs.
