EXPLORING THE IMPACT OF BODY-WORN CAMERAS ON DOWNSTREAM CRIMINAL JUSTICE AND EXTERNAL STAKEHOLDERS

Body-worn camera technology is a relatively new player in the field of criminal justice. As much as they are being reported on or discussed, in reality, body-worn cameras have not been in use long enough to have strong empirical support. Recent studies outlined some of the perceived benefits and costs of the body-worn cameras. Research has been done on both officer and citizen perceptions of the cameras, but little has been done in regards to other stakeholders, especially those in the criminal justice system. This study takes 13 interviews of community and criminal justice stakeholders in Tempe, Arizona and examines trends to identify unifying themes. The study found that 11 out of 13 stakeholders believed that the positives of the body-worn cameras outweighed the negatives. There was agreement among the parties that the strongest benefit of the cameras would be the transparency that it provides police departments, while most regarded the largest negative to be a lack of available resources to deal with the amount of data produced. As this is a small qualitative dataset, further research should be conducted about stakeholder perceptions in other cities, as well as solutions to some of the concerns raised by Tempe interviewees.

Evaluation of flood mitigation strategies for the Santa Catarina watershed using a multi-model approach

The increasingly recurrent extraordinary flood events in the metropolitan area of Monterrey, Mexico have led to significant stakeholder interest in understanding the hydrologic response of the Santa Catarina watershed to extreme events. This study analyzes a flood mitigation strategy proposed by stakeholders through a participatory workshop and are assessed using two hydrological models: The Hydrological Modeling System (HEC-HMS) and the Triangulated Irregular Network (TIN)-based Real-time Integrated Basin Simulator (tRIBS).

The stakeholder-derived flood mitigation strategy consists of placing new hydraulic infrastructure in addition to the current flood controls in the basin. This is done by simulating three scenarios: (1) evaluate the impact of the current structure, (2) implementing a large dam similar to the Rompepicos dam and (3) the inclusion of three small detention dams. These mitigation strategies are assessed in the context of a major flood event caused by the landfall of Hurricane Alex in July 2010 through a consistent application of the two modeling tools. To do so, spatial information on topography, soil, land cover and meteorological forcing were assembled, quality-controlled and input into each model. Calibration was performed for each model based on streamflow observations and maximum observed reservoir levels from the National Water Commission in Mexico.

Simulation analyses focuses on the differential capability of the two models in capturing the spatial variability in rainfall, topographic conditions, soil hydraulic properties and its effect on the flood response in the presence of the different flood mitigation structures. The implementation of new hydraulic infrastructure is shown to have a positive impact on mitigating the flood peak with a more favorable reduction in the peak at the outlet from the larger dam (16.5% in tRIBS and 23% in HEC-HMS) than the collective effect from the small structures (12% in tRIBS and 10% in HEC-HMS). Furthermore, flood peak mitigation depends strongly on the number and locations of the new dam sites in relation to the spatial distribution of rainfall and flood generation. Comparison of the two modeling approaches complements the analysis of available observations for the flood event and provides a framework within which to derive a multi-model approach for stakeholder-driven solutions.
