The information provided in this research will help to get policies waiting to be reviewed by legislators, and any new proposal that reaches the appropriate legislative chamber, reviewed without obstacles and will help to prevent youth violence. Upon completion of this research, the study shows that rates of youth violence have decreased based on programs implemented at the state government level with a stronger juvenile justice system holding offenders accountable to ensure public safety and reduce youth violence and victimization. The study shows that community and school involvement with law enforcement and government agencies are some of the strategies needed to help reduce gun violence and rebuild communities.展开更多

To better understand the role of each region, the relations between city regions need to be carefully studied. In this work, the human mobility relations between regions of Shanghai based on mobile phone data is explored. By formulating the regions as nodes in a network and the commuting between each pair of regions as link weights, the distribution of nodes degree, and spatial structures of communities in this relation network are studied. Statistics show that regions locate in urban centers and traffic hubs have significantly larger degrees. Moreover, two kinds of spatial structures of communities are found. In most communities, nodes are spatially neighboring. However, in the communities that cover traffic hubs, nodes often locate along corridors.展开更多
