This study aimed to collect data on the effectiveness of most of the fingermark visualisation reagents currently used on porous surfaces on fingermarks aged for up to 90?years, significantly extending the timescales for which such information exists. A limited subset of the variables associated with processing of old fingermarks was explored, with a focus on the use of 1,8 diazafluoren-9-one (DFO), 1,2-indandione, ninhydrin, and physical developer. These techniques were used in sequence on batches of cheques between 11 and 32?years old, and on documents dating from the 1920s and 1940s. The potential for applying a physical developer enhancement process (blue toning) as the final step in the sequence was also explored. The benefits of using processing sequences on porous items were clearly demonstrated, with all processes in the sequence adding value in terms of additional marks found on the cheques up to 32?years old. In addition, physical developer was found to be capable of developing fingermarks up to 90?years old, whereas the amino acid reagents appear less effective on documents of 70?years and older. An experimental physical developer formulation with reduced environmental impact was found to be as effective as the existing process in these experiments. Blue toning was found to visualise an additional 10–25% of marks, and its wider use after silver-based deposition processes is recommended based on the evidence from this study. 相似文献

It was during the Second World War that the Allies developed a sophisticated intelligence system to harness information garnered from the hundreds of thousands of Axis captives taken during hostilities. Indeed, prior to 1942, many Allied field commanders displayed a healthy scepticism towards intelligence obtained from this source. Such suspicions were eventually overcome. This article examines British efforts during the formative period 1939–42 when an integrated infrastructure was painstakingly established to extract, collate and assess material obtained from Axis POWs. It not only examines the intelligence organisations which were established by each of the British armed services, but also analyses the variety of military and political information obtained and how it was interpreted and disseminated. 相似文献

Humanitarian assistance is becoming more complex and the environment in which it operates more competitive. Nevertheless, humanitarianism is shielded from such pressures by a set of principles that are reflected in International Humanitarian Law (IHL) which all governments ostensibly accept. The issue for the wider international community as well as for donor and recipi ent governments and humanitarian organizations is whether such principles can endure in light of the dilemmas posed in times of conflict and post-conflict. Humanitarian Dilemmas in War and Peace explores the dilemmas that humanitarianism not only confronts but also creates in seeking to protect and preserve life of the disaster and emergency-affected. In so doing, it views humanitarianism from three perspectives: (i) humanitarian principles in times of conflict; (ii) humanitarian principles from the perspective of many within the Group of 77; and (iii) humanitarianism from the perspective of institutional survival. The opinion piece concludes that, despite the dilemmas suggested by these perspectives, humanitarian principles can be upheld even amidst the complex and com petitive aid environment. It would require inter alia a more focused definition of humanitarian action, mechanisms that hold humanitarian organizations to higher standards of accountability, a commitment to more consistent and coherent advocacy and greater strategic perspectives to anticipate and respond to factors creating large-scale human vulnerability. 相似文献

International donors and development INGOs are increasingly recognising the potential contributions that Diasporas can make to developing countries. However, traditional peacebuilding literature has largely ignored the potential of Diasporas to contribute to post conflict reconstruction in the homeland. This article, therefore, assesses this potential through an examination of the Bosnian World Diaspora Network, created after the recent dispersal of refugees due to the conflict in Bosnia. It concludes that the relationship between, on the one hand, diaspora activities and, on the other, armed conflict and war recovery is considerably less straightforward than has been supposed. However, it does suggest a number of ways in which donors/host lands could assist the coordination of development agencies and diaspora networks. 相似文献

Drug users often define themselves as functional users and depict others as dysfunctional (i.e. junkies). Previous research on the social identities of drug users has focused on the symbolic boundaries they create to distance themselves from stigmatized others. Investigators have yet to focus on how users account for their own boundary violations. Here, we examine the narratives of 30 former women methamphetamine (meth) users to determine how they make distinctions between functional and dysfunctional meth users (i.e. “meth heads”). The distinctions they make are based on users’ abilities to maintain control of their lives and to hide their use from outsiders. Those who saw themselves as functional but who engaged in behaviors inconsistent with this image accounted for these behaviors to maintain desired identities. We show the complexity of drug users’ identities and illustrate how anti-drug campaigns that provide grotesque caricatures of drug users may prolong drug using careers. 相似文献
