Comparative study of electrochromic enhancement of latent fingerprints with existing development techniques

To address the challenge of capturing latent fingerprint evidence from metal surfaces, a new method of latent fingerprint enhancement based on electrochromic polymer films has recently been developed. Here, we present a study comparing the development and visualization of nonvisible fingerprints on stainless steel substrates using this electrochromic enhancement approach with three classical methods (dusting, wet powder, and cyanoacrylate fuming). Two variants of the electrochromic enhancement method were utilized with polyaniline and poly(3,4-ethylenedioxythiophene) as the electrochromic materials. Fingerprint samples were taken from different donors (varying in age and gender) and were exposed to different environments for systematically varied periods of time (up to 28 days). The environments represent plausible evidential scenarios: left under ambient conditions, washed with aqueous soap solution, washed with acetone, submerged in water, and maintained at elevated temperature. The electrochromic enhancement procedure frequently outperformed the traditional methods, particularly for samples exposed to more challenging histories.     

International Cultural Affairs: A Fourteen Country Survey

Abstract

Alas there has been no serious effort to sponsor research in the field of cultural relations. Because governments and other major bodies concerned with funding cannot see any obvious application or “pay-offs” for such investigations, they simply have not been carried out. (Mitchell 1986)

PUBLIC ADMINISTRATION REFORM IN POST‐CONFLICT SOCIETIES: LESSONS FROM ACEH,INDONESIA

Post‐conflict reconstruction programs increasingly include components designed to strengthen the performance of the public service and to support public sector reform. Although there is a growing body of literature on the relationship between public administration, and peace and development, there have been few case studies of donor efforts to strengthen public administration as part of post‐conflict reconstruction. This study examines efforts to strengthen the civil service in Aceh, Indonesia, following the province's first post‐conflict elections in 2006. It examines the impact of a donor‐funded program designed to assist Aceh's first post‐conflict administration (2007–2012) to reform its personnel management practices. The case study sheds light on weaknesses in current donor approaches to public administration reform in post‐conflict situations. Copyright © 2012 John Wiley & Sons, Ltd.
