Not by accident: An analytical approach to traffic crash harm reduction

Purpose

This study examines whether a problem-oriented approach used by police in Cincinnati, Ohio called the Crash Analysis Reduction Strategy (CARS) corresponded with a change in the number of traffic crashes that resulted in injuries after implementation onset. Under the CARS model, police developed tactics that focused on targeting high-risk driving behaviors, impaired drivers, and crash hotspot locations within the city.

Methods

Using a two-phase strategy we first assess local impact by examining injury-related traffic crash patterns at targeted locations. Second, we examine whether traffic crashes that resulted in injuries in Cincinnati significantly diverged relative to similar outcomes across a number of comparison sites.

Results

Difference-in-difference negative binomial regression analyses indicates that traffic crashes were significantly lower in Cincinnati - down roughly 5.7% to 10.3% in the post-intervention period - when contrasted with comparison sites.

Conclusions

Our findings suggest that comprehensive problem solving approaches can significantly reduce the risk of life changing events such as automobile crashes that result in injuries beyond traditional policing efforts that explicitly focus on crime and violence.     

The Search for “Fred”: An Unusual Vertical Burial Case,

Police witness intelligence stated a murdered adult male “Fred” had been vertically buried in wooded hilly terrain 30 years ago in the Midlands, U.K. Conventional search methods were unsuccessful; therefore, the police requested a geophysical investigation to be undertaken to determine whether “Fred” could be detected. A multiphased geophysical approach was conducted, using bulk ground conductivity and metal detectors, then follow‐up magnetics and ground penetrating radar (GPR) survey profiles on electromagnetic (EM) anomalous areas. A tight grid pattern was used to account for the reduced target size. Relatively high‐resolution EM and GPR techniques were determined optimal for this terrain and sandy soil. Geophysical anomalies were identified and the most promising intrusively investigated, and this was found to be a large boulder and tree roots. Study implications suggest careful multiphase geophysical surveys are best practice and give confidence in cold case searches. This study yielded a no‐body result, effectively saving police time and costs from further investigations.     

Public preferences regarding police facebook posts: a macro-level analysis

ABSTRACT

Police agencies have adopted social media quite widely, but researchers have paid relatively little attention to the phenomenon. To date few studies have explored public reaction to police use of social media. The current study uses a purposive sample with 7,116 police Facebook posts collected from 14 different police agencies during a one-year period to answer two principal research questions: (1) with respect to the number of likes, number of shares, or number of comments regarding different themes present in police Facebook posts, are there differences among police agencies corresponding to differences in the thematic content in their postings? and (2) What factors are related to the public reaction (i.e., likes, shares, comments) to a police Facebook post? The findings from ANOVA and negative binomial regression models clearly indicate that citizens do have definite preferences on police Facebook posts – they are more likely to like and make comments on posts of police personnel and police-public relations, but less likely to share posts of Social Networking Sites. Also, they are more prone to like posts with narratives and pictures, but less likely to favor posts containing hyperlinks. Policy implications and practice guidelines, study limitations, and future research are also discussed.     

Alexis de Tocqueville on the Covenantal Tradition of American Federal Democracy

Perhaps no analyst of democracy's potentials for despotism andself-government understood better than Alexis de Tocquevillethe importance of the "favorable circumstances" of America'srepublican and religious origins. America's covenantal heritageinspired the public philosophy of federal liberty and the federalprinciple used to establish governments and political associationsin colonial New England. The Puritans, Tocqueville explained,created the bonds and the liberties of citizenship by theirassent to eternal, transcendent principles, as well as by theirconsent to government. The principles of covenant ultimatelyprovided the institutional and conceptual foundation of constitutionalgovernment, making America's federal democracy less vulnerableto possessive individualism and democratic despotism. Federalprinciples fostered an important indirect role for religionin American politics. Tocqueville not only analyzed the tensionbetween the requirements of faith and democratic norms, butalso distinguished covenantal ways of negotiating these concernsfrom the approach taken by later advocates of religious freedom,fames Madison and Thomas Jefferson. He argued that federalism'smoral foundations will be difficult to preserve if this tensionis resolved in ways that promote individual autonomy by underminingcovenantal thinking.     

‘Strong,United and Independent’: the British Foreign Office,Anglo–Iranian Oil Company and the internationalization of Iranian politics at the dawn of the Cold War, 1945–46

This article challenges traditional accounts of the 1946 Cold War Crisis in Iran by moving beyond Soviet–American confrontation to focus on British policy. In contrast to the United States, Britain was a major stake-holding power in Iran due to the valuable holdings of the Anglo–Iranian Oil Company (AIOC). By comparing the reactions of the AIOC and Foreign Office, continuity between the events of the 1946 Crisis and later developments in the Mosaddegh premiership becomes apparent. Soviet interference in Azerbaijan prompted great concern from representatives in Iran, but the central Foreign Office pursued a more cautious policy. Only concerns relating to the growth of domestic Iranian communism in the form of the Tudeh Party and the threat this entailed to the British concession prompted the Foreign Office and AIOC to take measures rendering them partially complicit in the internationalization of Iranian politics, setting an important precedent for future action. This article evaluates the policy-making process and its impact on Anglo–Iranian relations by utilizing records from the UK National Archives, British Petroleum Archive and diplomatic personal papers.     

Nondestructive Biological Evidence Collection with Alternative Swabs and Adhesive Lifters

In forensic science, biological material is typically collected from evidence via wet/dry double swabbing with cotton swabs, which is effective but can visibly damage an item's surface. When an item's appearance must be maintained, dry swabbing and tape‐lifting may be employed as collection techniques that are visually nondestructive to substrates' surfaces. This study examined the efficacy of alternative swab matrices and adhesive lifters when collecting blood and fingerprints from glass, painted drywall, 100% cotton, and copy paper. Data were evaluated by determining the percent profile and quality score for each STR profile generated. Hydraflock^® swabs, BVDA Gellifters^®, and Scenesafe FAST? tape performed as well as or better than cotton swabs when collecting fingerprints from painted drywall and 100% cotton. Collection success was also dependent on the type of biological material sampled and the substrate on which it was deposited. These results demonstrated that alternative swabs and adhesive lifters can be effective for nondestructive DNA collection from various substrates.
