Again, in terms of our prison scenario, we see the apparent and pertinent aspects through the direct definitions of each stage; de-escalation (likely after some resolve has been implemented) and settlement (likely involved with the repercussions of the implemented course of action). An imperative move in resolving the racial divides that are undoubtedly formed within the model and infrastructure of this dilemma would exist in the sought counsel of a professional in terms of this issue. Whether that is some form of psychologist, anthropologist or other appointed and qualified expert in the field of group interactions and conflict, the expertise of such an individual, or group for that matter, may dictate the progression of resolution and the timeframe by which it will follow toward settlement. It may also prove effective to completely restructure the confined orders that permit any form of social development as a whole. The meal schedules, the meals themselves, the exercise allowance and those permitted to it, showering, working, etc. These are all aspects that must be dissected, analyzed and revised in a way suitable with the necessary changes that the prison seeks.

With the array of potentially successful conflict resolution methods available for implementation upon the prison scenario, there are likely a number of different ways by which their uses can be effectively deployed. My general opinion however,...

It is in this consideration that the conflict resolution methods would best suit this specific scenario by following the ideals of a suppressive resolve of conflict and clear and decisive promotion of aspects involved with playing down differences among the separate divides within both the prison population and the staff population. Including with these tactics, the implementation of authoritative command, whereby the superior authority of the prison control emphasizes a formal authority to resolve conflict followed by communication its desires with the parties involves (Bostrom, 1991). This method will systematically befall the ordinances of power or higher influences within each sect of division in both the prison population and also within the staff, as such has likely occurred through the conflict escalation of such nature.
