Analyzing the dynamics of international mediation processes Schrodt, Philip A. Gerner, Deborah J. Uploaded 07-16-2001 Keywords event data cross-correlation mediation Cox proportional hazard pattern recognition Abstract This paper presents initial results from a project that will formally test a number of the hypotheses embedded in the theoretical and qualitative literatures on mediation, using automated coding of event data from news-wire sources. In contrast to most of the existing quantitative literature, which emphasizes the structural aspects of mediation, we will focus on the dynamics. The initial part of the paper focuses on two issues of design. First, we discuss the advantages of generating data using fully automated methods, which increases the transparency and replicability of the research. This transparency is extended to the development of more complex variables that cannot be captured as single events: these are defined as pattern of the underlying event data. We also suggest that these can be usefully studied using conventional inferential statistics rather than computational pattern recognition. Second, we justify the "statistical case study" approach which focuses on a small number of cases that are limited in geographical and temporal scope. While the risk of this approach is that one will find patterns of behavior that apply only in those circumstances, we point out that the more conventional large-N time-series cross-sectional studies also carry inferential risks. The statistical tests reported in this paper look at three different issues using data on the Israel-Lebanon and Israel-Palestinian conflicts in the Levant (1979-1999), and the Serbia-Croatia and Serbia-Bosnia conflicts in the Balkans (1991-1999). First, cross- correlation is used to look at the effects of mediation on the level of violence over time. Second, we test the "sticks-or-carrots" hypothesis on whether mediation is more effective in reducing violence if accompanied by cooperative or conflictual behavior by the mediator. Finally, we estimate Cox proportional hazard models to assess the factors that influence (1) whether mediation is accepted by the parties in a conflict, (2) whether formal agreements are reached, and (3) whether the agreements reduce the level of conflict. Future work in the project involves development of a new event coding scheme specifically designed for the study of mediation, and expansion of the list of cases to include other mediated conflicts in the Middle East and West Africa.
