The application of infrared chemical imaging to the detection and enhancement of latent fingerprints: method optimization and further findings

Fourier transform infrared (FTIR) chemical imaging allows the collection of fingerprint images from backgrounds that have traditionally posed problems for conventional fingerprint detection methods. In this work, the suitability of this technique for the imaging of fingerprints on a wider range of difficult surfaces (including polymer banknotes, various types of paper, and aluminum drink cans) has been tested. For each new surface, a systematic methodology was employed to optimize settings such as spectral resolution, number of scans, and pixel aggregation in order to reduce collection time and file-size without compromising spatial resolution and the quality of the final fingerprint image. The imaging of cyanoacrylate-fumed fingerprints on polymer banknotes has been improved, with shorter collection times for larger image areas. One-month-old fingerprints on polymer banknotes have been successfully fumed and imaged. It was also found that FTIR chemical imaging gives high quality images of cyanoacrylate-fumed fingerprints on aluminum drink cans, regardless of the printed background. Although visible and UV light sources do not yield fingerprint images of the same quality on difficult, nonporous backgrounds, in many cases they can be used to locate a fingerprint prior to higher quality imaging by the FTIR technique. Attempts to acquire FTIR images of fingerprints on paper-based porous surfaces that had been treated with established reagents such as ninhydrin were all unsuccessful due to the swamping effect of the cellulose constituents of the paper.     

VERTICAL STRATEGIC ALIGNMENT AND PUBLIC SERVICE PERFORMANCE

We report the results of a study examining the effects of vertical strategic alignment (that is, the degree to which strategic stances are consistent across different organizational levels) on public service performance. Longitudinal multivariate analysis is undertaken on a panel of public organizations over four years. We find that alignment on a prospecting strategy leads to better performance, but that no such effect is observed for a defending strategy. We also find that high levels of prospecting alignment produce stronger positive performance effects in centralized organizations and when environmental uncertainty is high. The implications of these findings for research and practice are considered in the conclusion.     

Improving Russian Justice with Foreign Assistance: Model Courts and the Tactical Approach

This article argues that as an interactive, tactical approach to sharing good practices, model courts represent an especially fruitful vehicle for accomplishing judicial reform. This contention is illustrated with an assessment of Canadian and American judicial reform projects in Russia in creating model district courts and diffusing their experience to other courts throughout the country. Mechanisms of diffusion included both a new curriculum for the training of court staff and new instructions for case management, as well as the indirect spread of concepts and practices through social learning. The article goes on to explore the reasons for the success of these projects and the conditions under which the tactical approach is most appropriate.     

Corona over Cuba: The Missile Crisis and the Early Limitations of Satellite Imagery Intelligence

In the autumn of 1962, two weeks before U-2 aerial photographs confirmed Soviet deployments of nuclear missiles in Cuba, the US intelligence community attempted to image the island with the spy satellite Corona. Insufficient image resolution and extensive cloud cover, however, prevented this photography from providing solid evidence confirming or denying the presence of offensive missiles. This event – previously unaddressed either by Missile Crisis or Corona scholars – illustrates both the promise and the limits of early satellite imagery intelligence. It further provides insight into the early imagery tasking and coordination process and demonstrates needs that drove further development of national satellite reconnaissance in the years that followed.
