Description:Hughes analyzes the occurrence and resolution of dispute-related incidents involving black and white youth street gangs in Chicago. Quantitative analysis involves assessing situational variables suggested by the literature as relevant to the occurrence of violence. When possible, interaction sequences also are examined. Qualitative analysis emphasizes themes related to the conditions under which disputes are likely to emerge and either escalate into violence or be "squashed." The result is a conceptual scheme that is useful for understanding how factors and processes operating at the micro-social level contribute to the occurrence of disputes and impact the decision to engage in violence or to back down.
