The stream analogy of lethal violence (SALV) argues that homicide and suicide are similarly driven by frustration and aggression. SALV research has examined forces of production (i.e., lethal violence rate [LVR]) and forces of direction (i.e., suicide-homicide ratio [SHR]). The current study applies 6 foundational social disorganization theory (i.e., the systemic model) structural predictors and 3 unique social controls to help explain the LVR and SHR. Using data from 229 South Korean community areas, the study tracked lethal violence for 6 years for each area, yielding 1,374 observations for analysis. Findings reveal mixed support for the systemic model. Urban area was negatively associated with the SHR’s initial level, but positively associated with increased SHR rates of change. Variations in the residential instability and divorce rates had positive effects on only the initial LVR level. Children’s nursery facilities fully mediated the link between structural characteristics and increased SHR rates of change.

致命暴力（SALV）的流类比认为，凶杀和自杀同样是由挫折和侵略驱动的。SALV 研究检查了生产力量（即致命暴力率 [LVR]）和方向力量（即自杀-凶杀率 [SHR]）。目前的研究应用了 6 个基本的社会解体理论（即系统模型）结构预测因子和 3 个独特的社会控制来帮助解释 LVR 和 SHR。该研究使用来自 229 个韩国社区地区的数据，对每个地区的致命暴力进行了 6 年的跟踪，产生了 1,374 个观察结果进行分析。调查结果显示对系统模型的支持不一。城市地区与 SHR 的初始水平呈负相关，但与 SHR 变化率的增加呈正相关。居住不稳定和离婚率的变化仅对初始 LVR 水平产生积极影响。儿童托儿所充分调节了结构特征与增加的 SHR 变化率之间的联系。
