Chronicling the Complexification of Negotiation Theory and Practice

The essay reviews the content of twenty-five years of Negotiation Journal , identifying themes and issues explored on its pages in the past, the current issues challenging the field's scholars and practitioners, and the issues likely to confront us in the future. It argues that while we in the field hoped for simple, elegant, and universal theories of negotiation and conflict resolution, the last twenty-five years have demonstrated the increasing complexification of negotiation theory and practice, from increased numbers of parties and issues, and dilemmas of intertemporal commitments, ethics, accountability, and relationships of private action to public responsibility.     

The link between recurrent maltreatment and offending behaviour

This article considers recurrent maltreatment and offending behaviour. The sample was 60 males and 19 females (11 to 18 years) resident within a secure institution in England and considered a risk to themselves and/or others. Overall, 20.8% had not experienced maltreatment, 6.5% had experienced a single incident, 11.7% were repeat victims (same perpetrator), 6.5% were revictimised (different perpetrators), and more than half (54.5%) had suffered both repeat and revictimisation. Of those who had committed a violent and/or sexual crime, 74% had experienced some form of revictimisation, compared to 33% of those who committed nonviolent offences. Those young people most likely to have committed violent and/or sexual crimes were those who had been victims of recurrent extrafamilial maltreatment (many of whom had also experienced recurrent intrafamilial maltreatment). Thus, in this sample, revictimisation was associated with serious crimes. However, these findings are preliminary, and prospective research with a larger sample is needed.     

Informativeness of the CODIS STR loci for admixture analysis

Population admixture (or ancestry) is used as an approach to gene discovery in complex diseases, particularly when the disease prevalence varies widely across geographic populations. Admixture analysis could be useful for forensics because an indication of a perpetrator's ancestry would narrow the pool of suspects for a particular crime. The purpose of this study was to use Fisher's information to identify informative sets of markers for admixture analysis. Using published founding population allele frequencies we test three marker sets for efficacy for estimating admixture: the FBI CODIS Core STR loci, the HGDP-CEPH Human Genome Diversity Cell Line Panel and the set of 39 ancestry informative SNPS from the Shriver lab at Pennsylvania State University. We conclude that the FBI CODIS Core STR set is valid for admixture analysis, but not the most precise. We recommend using a combination of the most informative markers from the HGDP-CEPH and Shriver loci sets.
