Getting to the Table in Oslo: Driving Forces and Channel Factors

Using the secret Middle East peace talks in Oslo, Norway as a case example, the authors develop a conceptual framework for analyzing prenegotiation processes in negotiation. The framework focuses on understanding changes in the balance of geopolitical, internal, political, and group psychological forces that lead parties to negotiate. The framework also highlights the importance of channel factors, such as the use of unofficial representatives, small-state sponsorship, co-mediation, secret diplomacy, and staged agreements. Although developed with reference to the Oslo peace process, the authors believe this framework has broader applicability to the analysis of prenegotiation processes in international and ethnic disputes and other situations of protracted conflict. They conclude with a series of questions for future prenegotiation research.     

Analyzing linked systems of negotiations

This article presents a conceptual framework for analyzing the structure and dynamics of what the authors call linked systems of negotiations. Even such seemingly straightforward transactions as the purchase of a family car tend to involve linked negotiations. The framework highlights the importance of internegotiation processes in shaping Zones of Possible Agreement, and proposes a typology of linkage. By mapping out and reengineering linked systems, negotiators can enhance their ability to shape the structure within which their negotiations take place.     

Estimating Individual Contributions to Complex DNA SNP Mixtures.,

High‐throughput sequencing (HTS) of large panels of single nucleotide polymorphisms (SNPs) provides an alternative or complimentary approach to short tandem repeats (STRs) panels for the analysis of complex DNA mixture forensic samples. For STRs, methods to estimate individual contribution concentrations compare capillary electrophoresis peak heights, peak areas, or HTS allele read counts within a mixture. This article introduces three approaches (mean, median, and slope methods) for estimating individual DNA contributions to forensic mixtures for HTS/massively parallel sequencing (MPS) SNP panels. For SNPs, the major:minor allele ratios or counts, unique to each contributor, were compared to estimate contributor proportion within the mixture using the mean, median, and slope intercept for these alleles. The estimates for these three methods were typically within 5% of planned experimental contributions for defined mixtures.     

Stochastic amortization and manufacturing profitability

The quantitative analysis of manufacturing operations usually considers the amortization of physical assets, and allows for the cost of such assets in product prices. Typically, this involves the use of an asset's P/A ratio, where P is its initial cost and A is the net cash-flow or profit it generates in unit time. The simplest case, regarding asset life as fixed, is seldom credible, and a more realistic approach is to model the stochastic nature of asset lifetimes. In this paper, we demonstrate the efficacy of the strategy of calculating an average P/A, and show that the earning power of assets should increase with variability in lifetimes. We then argue that pricings based around this average are most useful with large numbers of assets, and that analysis of a small number requires a more considered approach. Finally, we consider the impact of estimating lifetime parameters on the approaches outlined.     

Posttraumatic Stress Disorder Symptoms,Relationship Adjustment,and Relationship Aggression in a Sample of Female Flood Victims

This study tested a model examining the interrelationships among posttraumatic stress disorder (PTSD) symptoms, intimate relationship adjustment, and intimate relationship aggression in a sample of 205 adult female flood victims. At the bivariate level, higher PTSD symptoms were associated with higher physical and psychological aggression victimization, poorer relationship adjustment, and higher physical and psychological aggression perpetration. Results from structural equation modeling (SEM) analyses indicated that relationship aggression victimization influenced aggression perpetration directly, and in the case of physical aggression, indirectly through its relationship with PTSD symptoms and relationship adjustment. The influence of PTSD symptoms on physical aggression perpetration was fully explained by poorer relationship adjustment. These findings extend prior work from other traumatized populations documenting associations between variables reflecting PTSD symptomatology and indices of relationship functioning, and indicate a need for further investigation in this area of inquiry.

The Relationship Between Psychopathic Personality Features and Malingering Symptoms of Major Mental Illness

This study examined the relationship between psychopathy and malingering in a subsample of male prison inmates (n = 55) participating in a larger study of the clinical utility of various assessment measures in correctional settings. Participants' capacity to feign major mental illness successfully was evaluated using standard cutoff scores for the detection of malingering on a variety of instruments, including the Structured Inventory of Malingered Symptomatology (SIMS; G. P. Smith & G. O. Burger, 1997), the Structured Interview of Reported Symptoms (SIRS; R. Rogers, R. M. Bagby, & S. E. Dickens, 1992), and the Personality Assessment Inventory (PAI; L. Morey, 1991). Psychopathic traits were assessed via the Psychopathic Personality Inventory (PPI; S.O. Lilienfeld & B. P. Andrews, 1996). Correlations between the malingering indices and the PPI were low (–.14 to .14) and not statistically significant. These findings fail to support the clinical intuition that individuals with higher levels of psychopathy are likely to be more adept at malingering.
