A network spatial analysis simulating response time to calls for service at variable staffing levels

Purpose – The purpose of this paper is to examine whether the distribution of police response time to in-progress burglaries differ according to the level of social disorganization across different neighborhoods. Design/methodology/approach – Using 2006 calls for service data collected from the Dallas and Houston Police Departments and from the 2000 US Bureau of Census statistics, the effects of social disorganization on police performance were examined through multilevel analysis of the distribution of police response time patterns across different neighborhoods in Dallas and Houston. Findings – The analysis of the DPD and HPD in-progress calls produced somewhat consistent findings on the relationship between the level of social disorganization and police response time. Concentrated disadvantage, immigrant concentration, and residential stability are important predictors of the distribution of police response time patterns in Dallas and Houston. Practical implications – Neighborhood social disorganization is related to the distribution of agency response time patterns. Detailed response time analysis is crucial for agencies to improve police performance and the community-police relationship. Originality/value – In the policing literature, researchers have tended to neglect rapid response when examining many aspects of policing. The present study expands on existing research by examining the theoretical link between the level of neighborhood social disorganization with the distribution of rapid police response to in-progress burglary in two cities.

Police administrators argue that they cannot experiment with reforms because of calls-for-service demand and lack of resources. This article looks at police staffing levels needed for a district operating under various models of police administration, such as the professional model and community-oriented policing. Using queuing theory as the methodology, the analysis illustrates that emergency service not only makes the most demands on staffing but also creates considerable idle time for administrators to implement reforms without sacrificing responsiveness to calls for service.

Neighborhood Level

Police response time to calls for service is a crucial factor in evaluation of police performance. While domestic violence is now considered serious interpersonal violence, factors associated with response time to domestic violence incidents are underexplored. Using hierarchical linear modeling, over 10,000 cases of calls for service for domestic violence across 438 census tracts in Houston, Texas, were examined. The result of multilevel analysis revealed that complainant’s race, weapon involvement, and day and time of incidents were associated with response time at the situational level. At the neighborhood level, concentrated disadvantage, immigration concentration, and residential stability were significantly associated with response time.

Access To Food

Recently, food security becomes a priority for many governments particularly in developing countries. Food security has four dimensions i.e. availability, accessibility, stability, and utilization. This study examined food accessibility in term of geographic access i.e. the contribution of the geographic environment to food choices and consumption. The study located in Tanjung Selor Subdistrict, the capital region of Bulungan Regency as well as North Kalimantan Province. Geographic access to food was analyzed based on spatial distribution of food stores, settlement, and availability of transportation network. Spatial analysis, i.e. coverage, density, and network analysis, as well as the spatial visualization were performed using tools available in GIS software. This study revealed some circumstance related to geographical access to food in the study area. Geographical access to food for non-motorized people is limited. Non-motorized people have to walk more than 1 km to the nearest food store. Access to food for motorized people is somewhat different. Their geographical access, in general, were categorized as easy to moderate. This situation indicates that the availability of public transport or vehicle ownership is necessary to improve access to food.
