People ebb and flow across the city. The spatial and temporal patterning of crime is, in part, reflective of this mobility, of the scale of the population present in any given setting at a particular time. It is also a function of capacity of this population to perform an active role as an offender, victim or guardian in any specific crime type, itself shaped by the time-variant activities undertaken in, and the qualities of, particular settings. To this end, this paper explores the intra-daily influence of activities and settings upon the weekday spatial and temporal patterning of violent crime in public spaces. This task is achieved through integrating a transient population dataset with travel survey, point-of-interest and recorded crime data in a study of Great Manchester (UK). The research deploys a negative binomial regression model controlling for spatial lag effects. It finds strong and independent, but time-variant, associations between leisure activities, leisure settings and the spatial and temporal patterning of violent crime in public space. The paper concludes by discussing the theoretical and empirical implications of these findings.

人潮涌动，穿过城市。犯罪的空间和时间模式部分地反映了这种流动性，反映了特定时间任何给定环境中存在的人口规模。这也是这一群体作为罪犯、受害者或监护人发挥积极作用的能力的一个功能。在任何特定的犯罪类型中，其本身是由在特定环境中进行的随时间变化的活动及其质量所塑造的。为此，本文探讨了日常活动和环境对公共场所暴力犯罪的工作日时空格局的影响。这项任务是通过将瞬态人口数据集与大曼彻斯特（英国）研究中的旅行调查、兴趣点和犯罪记录数据相结合来实现的。该研究部署了控制空间滞后效应的负二项式回归模型。它发现了休闲活动、休闲环境与公共空间暴力犯罪的时空模式之间的强烈和独立但随时间变化的关联。本文最后讨论了这些发现的理论和实证意义。
