Subsequently, Lofdahl (2002) modeled the relationship between internal dynamics of growth and development rooted in the master variables, on the one hand, and propensities toward particular patterns of international trade and their environmental impacts, on the other. The fourth phase concentrates on the measurement of change in the master variables and implications for international relations. The focus is on the resulting distribution of states both within and across profiles (Wickbolt and Choucri 2006). Using fuzzy logic, made it possible to investigate more systematically and more accurate the distribution of states throughout the international system. This could be an important step in anticipating conflict-prone behavior. Also in this phase are some nascent efforts to conceptualize state behavior in cyberspace, and thus develop metrics to explore propensities for behaviors in cyberspace. Clearly an exact comparison between behaviors in ―real and virtual domains cannot be assumed. Considerable exploratory investigations are required. All of these initiatives are informative in their own right. Each one provides important insights and evidence about the antagonizing processes that lead to system-threatening dynamics and, in some cases, to overt conflict, violence and war.
