Abstract: This research uses four classification algorithms in standard and boosted forms to predict members of a class for an online community. We compare two performance measures, area under the ROC (Receiver Operating Characteristic) curve (AUC) and accuracy in the standard and boosted forms. The research compares four popular algorithms Bayes, logistic regression, J48 and Nearest Neighbor (NN). The analysis shows that there are significant differences among the base classification algorithms—J48 had the best accuracy. Additionally, the results show that boosted methods improved the accuracy of logistic regression. ANOVA was used to detect the differences between the algorithms; post hoc analysis shows the differences between specific algorithms. Collapse

Abstract: The effectiveness of threats in negotiations was examined by exploring two factors likely to affect it: implicitness, or the extent to which the threat mentions what action the perpetrator would take if the target does not comply; and timing, or the time when the threat is stated. Participants were given a negotiation scenario that differed only by the nature of the threat made by their counterpart. The design was a 2 (implicit vs. explicit threat) × 2 (early vs. late threat) factorial design with a control condition (no threat). The study showed that early-implicit and late-explicit threats were both more likely to elicit concessions than early-explicit and late-implicit threats. The two more effective threats were also the ones that made the perpetrator seem less aggressive. Further, perceived credibility mediated the positive effect that late-explicit threats had over late-implicit threats in eliciting concessions. These results support the claim that whether making the threat’s sanction implicit is effective depends on its timing, as the nature of bargaining moves and perceptions varies over time (Pruitt 1981). They suggest that the way in which a threat is stated may dramatically influence its effect on the target. Collapse
