How to prevent and control community risks?Identifying community burglary risk hotspots based on time-space characteristics

Community security and risk management is essential for urban governance.To identify community risks more accurately,the space-time characteristics of community burglary cases in a community located in C city are analyzed in this study based on data from 2018 to 2020 using the hot police theory.The results are as follows:(1)In terms of time,the occurrence of theft cases is closely related to seasonal changes and daily work and rest and is affected by social activities.(2)In terms of space,the type of community and surrounding environment affect the generation and distribution of household theft hotspots,while urban planning and reconstruction cause the dissipation and transfer of hotspots.Therefore,to prevent and control risk,infrastructure and urban environment renovation should be carried out,community governance efficiency should be improved,and police work mode should be transformed to avoid potential hotspots,except for targeted interventions on existing hotspots.

Qualitative Exploration and Correction Strategies of the Criminal Psychological Mechanism of the Burglars

In order to explore the criminal psychological mechanism of burglars,this study adopts the qualitative research method of grounded theory to conduct in-depth interviews with 41 burglars in two prisons in Jiangxi Province,China.Nvivo 11.0 was used to code-construct and qualitatively analyze the interview content in order to refine the influencing factors and psychological evolution process of burglary behavior.Thefindings revealed that(1)burglary risk factors include burglary cognition,burglary motivation,burglary decision-making,delinquent peers,burglary opportunity,and incomplete reformation.(2)There are three stages in the psychological evolution pro-cess of burglars:cognitive formation,motivational dominance,and behavioral decision.(3)The interpretation of the criminal psychological mechanism of burglars is a comprehensive and dynamic outcome of the interaction of internal and external factors that shape the individual.Participants’inspection and non-participants’inspection were adapted to verify the research results’validity,which showed that the results were reliable.

On the Exploitation of Secondary Fibre Transfer： The Use of Flock Fibres as a Tracer

Objective Flock fibres are proposed as a tracer in cases where secondary transfer of the tracer is needed. Methods The research was carried out following a case in which people were suspected to commit large numbers of burglaries. Fibres were applied to the vehicle of the suspects and collected from later crime scenes. A device was developed to assist in the appli- cation of fibres and a number of experiments on secondary transfer were carried out. Results The device can be used to apply many fibres homogeneously in a short time. A single contact will not fully deplete the first surface from flock fibres. 1%~15% of the fibres are transferred to the 3rd surface representing the crime scene. The actual number of transferred fibres is dependent on variables such as the choice of surfaces. Conclusion The results indicate that, given the selected parameters, it is realistic to expect that relatively large numbers of fibres are transferred to a crime scene and can be collected.
