"International Peacebuilding: A Theoretical and Quantitative Analysis" by Doyle and Sambanis (2000). This article provided a quantitative analysis of archival data to determine the correlations between peacebuilding strategies and variables of hostility, local capacities, and international capacities. Thus archival research was used for this study. This type of research was appropriate for the study since the variables were operationally defined, based on theoretical assumptions, to represent data related to previous wars.
Data collection procedures included the gathering of statistics related to the variables. The data set included all civil wars since 1944 that ended by 1997. This allowed peacebuilding outcomes of at least two years following the end of wars to be included in the analysis. Civil war was defined as "an armed conflict that meets all the following conditions: causes more than 1,000 deaths overall and in at least a single year; challenges the sovereignty of an internationally recognized state; occurs with the recognized boundary of that state; involves the state as a principal combatant; includes rebels with the ability to mount organized armed opposition to the state; and has parties concerned with the prospect of living together in the same political unit after the end of the war" (p. 784). This definition allowed for data from several sets that combined wars, which provided a large and representative sample for analysis.
The variables measured represented factors that are theoretically viewed as interacting in a manner that presents a space for peace. An interactive model was used which stated that decisions to support peacebuilding are increased by local and international capacities for peace. For this model net local capacities are the difference between local capacities or developmental potential minus war-generated hostility, and international capacities substitutes for deficiencies in local ca...
