Given the increase of reconciliation processes initiated amid on-going violence, this study focuses on community reconciliation and its relation to structural transformation, or social reconstruction through reforming unjust institutions and practices that facilitate protracted violent conflict. Drawing lessons from the Caribbean coast of Colombia, mixed method analyses include eight in-depth interviews and 184 surveys. Four key dimensions of reconciliation – truth, justice, mercy, peace – are examined. In the interviews, participants prioritize reconstructing the truth and bringing perpetrators to justice as essential aspects of reconciliation. Notions of mercy and forgiveness are less apparent. For the participants, sustainable peace is dependent on structural transformation to improve livelihoods. These data, however, do not indicate how this understanding of reconciliation may relate to individual participation in reconciliation processes. Complementing the qualitative data, quantitative analyses identify some broad patterns that relate to participation in reconciliation events. Compared to those who did not participate, individuals who engaged in reconciliation initiatives report higher levels of personal experience with violence, live alongside demobilized paramilitaries, are more engaged in civic life, and express greater preference for structural transformation. The paper concludes with policy implications that integrate reconciliation and structural transformation to deepen efforts to rebuild the social fabric amid violence.

A novel way of cooking rice to maximize the removal of the carcinogen inorganic arsenic (Asi) is presented here. In conventional rice cooking water and grain are in continuous contact, and it is known that the larger the water:rice cooking ratio, the more Asi removed by cooking, suggesting that the Asi in the grain is mobile in water. Experiments were designed where rice is cooked in a continual stream of percolating near boiling water, either low in Asi, or Asi free. This has the advantage of not only exposing grain to large volumes of cooking water, but also physically removes any Asi leached from the grain into the water receiving vessel. The relationship between cooking water volume and Asi removal in conventional rice cooking was demonstrated for the rice types under study. At a water-to-rice cooking ratio of 12:1, 57±5% of Asi could be removed, average of 6 wholegrain and 6 polished rice samples. Two types of percolating technology were tested, one where the cooking water was recycled through condensing boiling water steam and passing the freshly distilled hot water through the grain in a laboratory setting, and one where tap water was used to cook the rice held in an off-the-shelf coffee percolator in a domestic setting. Both approaches proved highly effective in removing Asi from the cooking rice, with up to 85% of Asi removed from individual rice types. For the recycled water experiment 59±8% and 69±10% of Asi was removed, on average, compared to uncooked rice for polished (n=27) and wholegrain (n=13) rice, respectively. For coffee percolation there was no difference between wholegrain and polished rice, and the effectiveness of Asi removal was 49±7% across 6 wholegrain and 6 polished rice samples. The manuscript explores the potential applications and further optimization of this percolating cooking water, high Asi removal, discovery.

During Northern Ireland’s transition towards peace the role of the police as an actor in the conflict has been a key point of contention. As such, the reform of policing has been central to conflict transformation. Within this process, the role of dialogue about what policing had been and could be in the future has been vital. Such institutional post violence change processes have been hugely significant in illustrating both organisational resistance to change and the need for transitions to be powerfully manoeuvred through complex, political, organisational and cultural processes (Buchanan and Badham 1999; Pettigrew 2012). The radical and reforming nature of policing transition (Murphy 2013) has been both organisationally challenging (requiring significant transformational leadership, resourcing and external engagement from wider civic society) and politically unusual. Indeed, in a society emerging from violence the NI police are the only public sector organisation to have engaged structurally and culturally in understanding the point at which their core roles intersected with the ‘management’ of the conflict in NI generally. This paper presents an analysis of the role of historical dialogue in organisational change process, using the RUC / PSNI case. It proposes that historical dialogue is not just an external, societal process but also an internal organisational process and as such, has implications for managing institutional change in societies emerging from conflict. In doing so, it builds theoretical links between literature on conflict transformation and that on organisational memory and empirically explores messaging internal to the RUC before and during the four main periods of organisational change (Murphy 2013), with dialogue aimed at an external audience. It offers an analysis of how historical dialogue itself impacts on and is impacted by the organisational realities of change itself.
