Leveraging Wireless Broadband to Improve Police Land Mobile Radio Programming: Estimating the Resource Impact

Despite rapid growth in criminological studies of police technology, examinations of police land mobile radios are absent in the literature. This is troubling given the central role mobile radios serve in police operations and their significant management costs. The present study seeks to fill this gap by introducing the functionality of wireless broadband radio programming. Current practice requires a police officer to physically drive to a radio programming location to manage their mobile radio. Wireless programming remedies this burdensome reality, thereby saving officer time and cost. Geospatial analyses are used to estimate distance saved associated with wireless programming. We then conduct a number of calculations to determine time and cost savings related to the observed differences between existing and wireless radio programming within the context of the North Carolina State Highway Patrol. Results suggest wireless radio programming can save significant personnel and financial resources. Implications are discussed

Does GPS supervision of intimate partner violence defendants reduce pretrial misconduct? Evidence from a quasi-experimental study

Objectives This research examines the effect global positioning system (GPS) technology supervision has on pretrial misconduct for defendants facing intimate partner violence charges. Methods Drawing on data from one pretrial services division, a retrospective quasi-experimental design was constructed to examine failure to appear to court, failure to appear to meetings with pretrial services, and rearrest outcomes between defendants ordered to pretrial GPS supervision and a comparison group of defendants ordered to pretrial supervision without the use of monitoring technology. Cox regression models were used to assess differences between quasi-experimental conditions. To enhance internal validity and mitigate model dependence, we utilized and compared results across four counterfactual comparison groups (propensity score matching, Mahalanobis distance matching, inverse probability of treatment weighting, and marginal mean weighting through stratification). Results Pretrial GPS supervision was no more or less effective than traditional, non-technology based pretrial supervision in reducing the risk of failure to appear to court or the risk of rearrest. GPS supervision did reduce the risk of failing to appear to meetings with pretrial services staff. Conclusions The results suggest that GPS supervision may hold untapped case management benefits for pretrial probation officers, a pragmatic focus that may be overshadowed by efforts to mitigate the risk of pretrial misconduct. Further, the results contribute to ongoing discussions on bail reform, pretrial practice, and the movement to reduce local jail populations. Although the cost savings are not entirely clear, relatively higher risk defendants can be managed in the community and produce outcomes that are comparable to other defendants. The results also call into question the ability of matching procedures to construct appropriate counterfactuals in an era where risk assessment informs criminal justice decision-making. Weighting techniques outperformed matching strategies

Officer Perceptions of the Impact of Mobile Broadband Technology on Police Operations

Research examining police departments' use of technology is underdeveloped relative to other areas of policing. This gap in the literature is troubling as policing models are becoming more data-driven and thus, relying more heavily on information technologies. Arguably, the most commonly utilised technology in policing practice, and examined in policing research, has been mobile computers. However, there has been little insight into the technological advancement in data communications that directly influence the functionality of mobile computers. This research seeks to inform this shortcoming by examining a police department that implemented a dedicated wireless mobile broadband system. A mixed-methods approach is employed within a medium-sized department in the northeast region of the USA. Survey data were gathered from 76 uniformed police personnel. Semi-structured interviews were conducted with key personnel to further contextualise survey results. Survey results suggest tentative support for improved time savings and execution of job tasks after the implementation of wireless broadband. Perceptions of mobile broadband impacts on information flow, quality, and accessibility appear positive. Considerations for future research and study limitations are discussed

Police as Alert Responders? Lessons Learned about Perceived Roles and Responses from Pretrial GPS Supervision of Domestic Violence Defendants

There is a substantial body of literature that examines police practices, behavioural responses, and victim cooperation when the police respond to intimate partner or domestic violence (IPV/DV) incidents. Less scholarly attention is given to the complex justice system response to IPV/DV incidents in which the police are one of many collaborative actors. A critical time in IPV/DV justice system processing is the period of time after arrest and before court disposition. Increasingly, the supervision of defendants in this pretrial period has been facilitated with the use of technology that creates new roles for the police. The present study seeks to explore perceived police roles and responses through an in-depth case study of a city-county municipality employing global positioning system pretrial supervision of IPV/DV defendants. Using interview data from pretrial probation officers, victim advocates, and victims of IPV/DV, this research offers lessons learned and police practice recommendations for working as a unified systems front to curtail IPV/DV crimes and improve communication between multiple justice system stakeholders

Wireless Broadband for Municipal Police: Evaluating Clearance Times of Calls for Service

Though research has explored impacts of mobile computing and information technology on police operations, the literature lacks exploration of large-bandwidth data-sharing technologies that enhance the utility of mobile computing terminals. As part of a federally funded project, the present study employs a longitudinal pre- and postdesign utilizing 7 years of computer-aided dispatch data from a medium-sized municipal police department in the New England region. Pooled time series analyses are employed to examine the effect of wireless broadband implementation on clearance time of calls for service. Findings offer tentative support that clearance times for service calls decreased with the implementation of a wireless broadband network. Implementation did not appear to generate differential effects in areas that had experienced past challenges with cellular communication signals. Implications are provided, with an emphasis on the development of additional knowledge on technological evaluations

Spatiotemporal Convergence of Crime and Vehicle Crash Hotspots: Additional Consideration for Policing Places

Policing strategies that seek to simultaneously combat crime and vehicle crashes operate under the assumption that these two problems have a corollary relationship—an assumption that has received scant empirical attention and is the focus of the present study. Geocoded vehicle crash, violent crime, and property crime totals across were aggregated to Indianapolis census blocks over a 36-month period (2011-2013). Time series negative binomial regression and local indicators of spatial autocorrelation analyses were conducted. Results indicate that both violent and property crime are significantly related to vehicle crash counts, both overall and during the temporal confines of patrol tours. Relationship strength was modest. Spatiotemporal analysis of crime and crash data can identify places for police intervention and improved scholarly evaluation

Predicting Initiator and Near Repeat Events in Spatiotemporal Crime Patterns: An Analysis of Residential Burglary and Motor Vehicle Theft

Near repeat analysis has been increasingly used to measure the spatiotemporal clustering of crime in contemporary criminology. Despite its predictive capacity, the typically short time frame of near repeat crime patterns can negatively affect the crime prevention utility of near repeat analysis. Thus, recent research has argued for a greater understanding of the types of places that are most likely to generate near repeat crime patterns. The current study contributes to the literature through a spatiotemporal analysis of residential burglary and motor vehicle theft in Indianapolis, IN. Near Repeat analyses were followed by multinomial logistic regression models to identify covariates related to the occurrence of initiator (the first event in a near repeat chain) and near repeat (the subsequent event in a near repeat chain) events. The overall findings provide additional support for the argument that neighborhood context can influence the formation and context of spatiotemporal crime patterns

Impact of Mobile Broadband Data Access on Police Operations: An Exploratory Case Study of One Medium-Sized Municipal Police Department

As used in this study, “mobility” refers to “an inherent ability to move about,“ and “mobile computing” is a generic term that refers to the functional capabilities possible for end users as they complete tasks from various physical locations. “Broadband” refers to the relatively wide bandwidth characteristics of the wireless transmission medium and its corresponding ability to support multiple users and/or transport suitable quantities of data. “Mobile broadband” is used as a generic term to collectively refer to both terms in the context of the aggregate capabilities made possible through their use compared to other available mobile solutions and/or data. This study notes the lack of public-safety access to wireless broadband data, given resource limitations and a lack of independent evidence that would justify procurement of such technologies for police work. The current study’s deployment and assessment of this technology involved its use by the Brookline Police Department (BPD). Overall, the semi-structured interviews suggest that the wireless broadband technology was implemented with minimal difficulties and produced a number of perceived benefits for the BPD. The most direct benefit was the ease with which departmental technologies could be managed. Additional benefits were associated with increased access to timely information, increased information flow, and increased quality of reports. Structured interviews indicated that a few weeks of training sessions and ongoing informal bulletin and email disseminations were needed to overcome skepticism about the transition to wireless broadband. Most of the uniform personnel did not oppose the implementation nor did they perceive that the department was opposed to the transition. 39 tables, 3 figures, 93 references, and appended methodological details and supplementary data.National Institute of Justice (NIJ), US Department of Justice, Grant Number: 2010-IJ-CX-K02

A Case Study of Mississippi State Penitentiary’s Managed Access Technology

Managed access technology allows the completion of authorized calls placed from approved phone numbers (numbers that have been vetted and entered into a database) while blocking calls to or from devices or numbers that have not been pre-approved. This process is often referred to as “white-listing.“ The overall conclusion of this study is that managed access technology does capture a large quantity of cellular transmissions, but it is impossible to determine the rate with which attempted calls or texts successfully elude detection by the system. Even if a hypothetical rate of successful transmission detection was only 40 percent, however, that 40 percent would provide a substantial value-added effect to combating contraband cell phones. Thus, the decision about whether or not to use managed access technology is whether its possibly limited impact (blocking less than 100 percent of contraband calls) is sufficient to warrant the cost of installing and maintaining the managed access system. A series of interviews and teleconferences, in addition to the secondary analysis of managed-access system data, were used to produce a fundamental understanding of managed access technology operations, identify challenges and lessons learned, and develop a baseline of contraband cell phone activity. This report acknowledges that the study did not attempt to quantify potential vulnerabilities or manipulations of managed access systems. Although such an evaluation would be beneficial, it was beyond the scope of this study. 18 figures, 13 tables, 40 references, and appended examples of contraband cell phone activity, MSP managed access system infrastructure, and evaluation protocolsNational Institute of Justice (NIJ), U.S. Department of Justic

The Thiol-Rich Interlayer in the Shell/Core Architecture of Mussel Byssal Threads.

The mussel byssus thread is an extremely tough core-shelled fiber that dissipates substantial amounts of energy during tensile loading. The mechanical performance of the shell is critically reliant on 3,4-dihydroxyphenylalanine's (Dopa) ability to form reversible iron-catecholate complexes at pH 8. However, the formation of these coordinate cross-links is undercut by Dopa's oxidation to Dopa-quinone, a spontaneous process at seawater conditions. The large mechanical mismatch between the cuticle and the core lends itself to further complications. Despite these challenges, the mussel byssus thread performs its tethering function over long periods of time. Here, we address these two major questions: (1) how does the mussel slow/prevent oxidation in the cuticle, and (2) how is the mechanical mismatch at the core/shell interface mitigated? By combining a number of microscopy and spectroscopy techniques we have discerned a previously undescribed layer. Our results indicate this interlayer is thiol rich and thus will be called the thiol-rich interlayer (TRL). We propose the TRL serves as a long-lasting redox reservoir as well as a mechanical barrier
