Sexual division of antibacterial resource defence in breeding burying beetles, Nicrophorus vespilloides

A key component of parental care involves defending resources destined for offspring from a diverse array of potential interspecific competitors, such as social parasites, fungi and bacteria. 2. Just as with other aspects of parental care, such as offspring provisioning or brood defence, sexual conflict between parents may arise over how to share the costs of this form of care. There has been little previous work, however, to investigate how this particular burden might be shared. 3. Here, we describe a hitherto uncharacterized form of parental care in burying beetles Nicrophorus vespilloides, a species which prepares carrion for its young and faces competition from microbes for this resource. We found that parents defend the carcass with antibacterial anal exudates, and that the antibacterial activity of these exudates is only upregulated following the discovery of a corpse. At the same time, phenoloxidase activity in the anal exudates is downregulated, indicating parallels with the internal insect immune system. 4. In unmanipulated breeding pairs, females had higher antibacterial activity in their anal exudates than males, suggesting sex-specific roles in this aspect of parental care. 5. When we experimentally widowed males, we found that they increased levels of antibacterial activity in their anal exudates. Experimentally widowing females, however, led them to decrease levels of antibacterial activity in their anal exudates. Widowed beetles of each sex thus produced anal exudates of comparable antibacterial activity. We suggest that this flexible division of antibacterial activity may be coordinated by Juvenile Hormone. © 2009 British Ecological Society.

Rethinking Amnesties: Atrocity, Accountability And Impunity In Post-Conflict Societies.

The notion of accountability that is propagated in transitional justice often appears limited to demands for the prosecution and imprisonment of those who have been involved in serious human rights violations. Amnesties, widely understood as the absence of punishment for wrongdoing, are in turn considered by many scholars and activists as an example par excellence of the kind of Faustian pacts which are made in the name of political expediency in transitions from conflict. Drawing from a range of interdisciplinary literature, as well as research completed by the authors in a number of societies with a violent past, this paper uses amnesties as a case-study to argue for a more rounded interrogation of the notion of accountability in transitional justice. The paper charts the various forms of intersecting accountability which both shape and delimit amnesties at key ‘moments’ concerning their remit, introduction and operation. The paper concludes that the legalistic view of amnesties as equating to impunity and retribution as accountability is inaccurate and misleading. It argues that a broader perspective of accountability speaks directly to the capacity for amnesties to play a more constructive role in post conflict justice and peacemaking.

Punishment, blame and stigma after conflict: the experience of politically motivated former prisoners in Northern Ireland

This paper examines the relationship between the politics of blame in post-conflict Northern Ireland and the treatment of politically motivated former prisoners. Using the examples of direct and indirect discrimination in the areas of employment and access to mental health services, the paper considers how the discursive operation of blaming produces evasions and attributions of guilt. It argues that such blaming practices have very real material consequences for the allocation or withholding of goods and burdens in the community. The paper notes also that the ‘cause of victims’ is often appropriated by the press and other political actors for their own purposes, frequently to block the provision of public goods to one particular group of ex-combatants: ex-politically motivated prisoners. It concludes by posing a series of questions about blaming, justice and the moral authority of the victim in a transitional justice context. The claim of the paper is simply to offer some starting points for understanding the relationship between processes of blame, stigma and social exclusion.

Policing for peace in Northern Ireland: Change, conflict and community confidence

The fundamental change in policing that began in 2001 was a critical part of the Northern Ireland peace process. Seventy years after its establishment the Royal Ulster Constabulary (RUC) remained distrusted and unrepresentative of the Catholic – nationalist community. This book explores how policing changed and the significant contribution that overhaul made to the most successful conflict transformation process in recent decades. It looks at policing from an organizational perspective and focuses on leadership, strategy and culture as it traces the journey from RUC to PSNI. In this way it reflects the views of many key figures inside the organization and of key political decision makers outside of it. This book will be of tremendous interest to those seeking to explore the underlying dynamics of one of the most radical and challenging change processes in recent history and is a must read for anyone interested in the Northern Irish peace process.

Unlocking synergies between business units: internal value creation at Royal Vopak.

This paper examines the process of creating and exploiting synergies between business units of a multi-unit corporation and the creation of internal value by combining and exploiting knowledge. It offers a framework to create and manage such synergies and undertakes an empirical test through in-depth study across three business units of Royal Vopak, a Dutch-based global multi-unit corporation. Finally, it offers lessons for corporate managers trying to create and manage cross-unit synergies.
