This paper highlights the role of narratives in expressing, shaping and ordering urban life, and as tools for analysing urban conflicts. The paper distinguishes analytically between two prominent epistemological meta-narratives in contemporary urban studies and multiple ontological narratives in a given city-in this case Belfast. The first meta-narrative represents cities as sites of deepening coercion, violence and inequality and the second sees them as engines of new forms of transnational capitalism. Both are marked by the strategy of specifying 'exemplar' or 'paradigm' cities. The core of the paper addresses how these two meta-narratives map onto and interact with, three contemporary ontological narratives of urban regeneration in Belfast. We conceive of narratives-epistemological and ontological-as analytical tools and objects of analysis but also as tools for social action for competing political and economic interests and coalitions. While in the urban studies literature Belfast is typically studied as an exemplar 'conflict city', it is now being promoted as a 'new capitalist city'. In the context of post-Agreement Belfast, we explore not only the 'pull' of exemplar narratives but also resistances to them that are linked to multiple and hybrid senses of place in the city. We conclude that any significant move beyond the exigencies of rampant commodification or recurring inter-communal antagonism must firstly, encourage new forms of grassroots place-making and, secondly, reform of Belfast's (and Northern Ireland's) fragmented governance structures. © 2013 Copyright Taylor and Francis Group, LLC.

This paper examines the experiences of children in post-conflict Belfast as peace and social change afford new opportunities at the same time as they regulate behaviours and spatial practices. Theoretically and empirically it draws on the concept of environmental affordances in order to map the experiences of 11-year-old children in separate inner-city segregated and middle-class communities. Whilst the recession has affected the pace of urban restructuring, children in the expanding mixed and largely middleclass city extract multiple advantages from their area in ways not available to segregated communities. The paper concludes by highlighting the implications for effective listening strategies in the management of divided communities. © 2011 Taylor & Francis.

Perhaps the weakest dimension of the ‘triple bottom line’ understanding of
sustainable development has been the ‘economic’ dimension. Much of the thinking
about the appropriate ‘political economy’ to underpin sustainable development has
been either utopian (as in some ‘environmental’ political views) or ‘business as usual’ approaches. Rejecting both of these utopian and realist views, it is clear from the papers presented here and the conference debates that something like ‘ecological modernisation’ is the preferred conceptualisation of ‘sustainable development’ within policy circles in Northern Ireland, the UK and other European states.

Despite the growing use of apologies in post-conflict settings, cases of non-apology remain unaddressed and continue to puzzle scholars. This article focuses on the absence of apology by non-state and anti-state actors by examining the case of the Cypriot armed group EOKA, which has refused to offer an apology to the civilian victims of its ‘anti-colonial’ struggle (1955–1959). Using field data and parliamentary debates, and drawing on comparisons, this article analyses the factors that contributed to a lack of apology. It is argued that the inherited timelessness of Greek nationalism, and the impression of a perpetual need for defence, set up textbook conditions for the development of a hegemonic discourse and prevented an apology for human rights violations.

Cytosolic phospholipase A2 (cPLA2) is thought to be the rate-limiting enzyme in the arachidonic acid/eicosanoid cascade. The ability of various agonists to increase steady-state cPLA2 mRNA levels has previously been reported. The current study delineates the contributions of transcriptional and post-transcriptional processes to the regulation of cPLA2 gene expression in response to a variety of agonists in cultured rat glomerular mesangial cells. Epidermal growth factor, platelet-derived growth factor, serum and phorbol myristate acetate all increase the half-life of cPLA2 mRNA transcripts, indicating a role for post-transcriptional modulation of gene expression. The presence of three ATTTA motifs in the 3' untranslated region (3'UTR) of the rat cPLA2 cDNA is ascertained. Heterologous expression of chimeric constructs with different 3'UTRs ligated into the 3' end of the luciferase coding region reveals that the presence of the cPLA2 3'UTR results in reduced luciferase activity compared with constructs without the cPLA2 3'UTR. Furthermore, the luciferase activity in the constructs with the cPLA2 3'UTR is increased in response to the same agonists which stabilize endogenous cPLA2 mRNA. A negligible effect of these agonists on transcriptional control of cPLA2 is evident using promoter-reporter constructs expressed in transient and stable transfectants. Taken together, these results indicate predominant post-transcriptional regulation of cPLA2 mRNA levels.

Northern Ireland is in the early stages of transition from conflict, but progress is regularly affected by political and public discontent. A divided landscape, segregated and under-resourced communities are enduring legacies of ‘the Conflict’. Yet the political will to tackle social and community division, consult with and support communities has been lacking. Grounded in six communities most affected by poverty and the Conflict this paper illustrates the difficulties, tensions and contradictions experienced during transition and how, in the process of ‘change’, children and young people have been silenced, marginalised and
demonised.

In societies emerging from conflict/war, sustained occurrence of violence appears to be a common feature. In Northern Ireland, while incidents of violent deaths and injuries specifically related to the political conflict have decreased dramatically since 1998, regular riots and paramilitary activity confirm continuing division and conflict. The study described here explored children’s perceptions of their own lives and their predecessors’ lives in the country, through a draw-and-tell technique (n=179). While multiple positive elements of peace/hope were depicted by the majority of children, especially in the pictures portraying the present, negative elements and violent references mostly appeared in the pictures representing the past. Violence was more likely to be portrayed by boys, older children, and those attending segregated education.
