Situating events and traces in time is an essential problem in investigations. To date, among the typical questions issued in forensic science, time has generally been unexplored. The reason for this can be traced to the complexity of the overall problem, addressed by several scientists in very limited projects usually stimulated by a specific case. Considering that such issues are recurrent and transcending the treatment of each trace separately, the formalisation of a framework to address dating issues in criminal investigation is undeniably needed. Through an iterative process consisting of extracting recurrent aspects discovered from the study of problems encountered by practitioners and reported in the literature, common mechanisms were extracted and provide understanding of underlying factors encountered in forensic practise. Three complementary approaches are thus highlighted and described to formalise a preliminary framework that can be applied for the dating of traces, objects, persons and indirectly events. 相似文献
Negotiation requires communication, but not necessarily verbal exchanges. Adjustments can be achieved incrementally by other means. This article will examine how some parties have managed to strike a deal in situations characterized by total distrust and even hostility, asymmetric power relations, major cultural differences, extreme logistical difficulties in reaching the place in which the trade is to be made, and several additional process risks by employing a type of bargaining known as “dumb barter.” This process presents a distinct paradigm with a specific and unique rationale. Sometimes called “silent trade,” it has been observed in many places (especially West Africa) for more than two millennia. It may well be the oldest form of trade negotiation and is still practiced in some parts of the world. An examination of this unlikely but real and effective process can also provide negotiation theorists with some useful insights into the fundamental nature of negotiation. 相似文献
Organised criminality is a great concern for national/international security. The demonstration of complex crimes is increasingly dependant on knowledge distributed within law-enforcement agencies and scientific disciplines. This separation of knowledge creates difficulties in reconstructing and prosecuting such crimes. Basic interdisciplinary research in drug intelligence combined with crime analysis, forensic intelligence, and traditional law enforcement investigation is leading to important advances in crime investigation support. Laboratory results constitute one highly dependable source of information that is both reliable and testable. Their operational use can support investigation and even provide undetected connections or organisation of structure. The foremost difficulties encountered by drug analysts are not principally of a chemical or analytical nature, but methodologies to extract parameters or features that are deemed to be crucial for handling and contextualising drug profiling data. An organised memory has been developed in order to provide accurate, timely, useful and meaningful information for linking spatially and temporally distinct events on a national and international level (including cross-border phenomena). Literature has already pointed out that forensic case data are amenable for use in an intelligence perspective if data and knowledge of specialised actors are appropriately organised, shared and processed. As a particular form of forensic case data, the authors' research focuses on parameters obtained through the systematic physical and chemical profiling of samples of illicit drugs. The procedure is used to infer and characterise links between samples that originate from the same and different seizures. The discussion will not, however, focus on how samples are actually analysed and compared as substantial literature on this topic already exists. Rather, attention is primarily drawn to an active and close collaboration between magistrates, forensic scientists, law enforcement investigators and crime analysts from different institutions with the aim of generating, using and validating relevant profiling case data as integral part of investigative and crime analysis processes. Original advances are highlighted through experiences from criminal investigations of offences related to the unlawful importation, exportation, supply and possession of illicit drugs. 相似文献

AbstractThe objective of this paper is to show how a formal approach to networks can make a significant contribution to the study of cross-border trade in West Africa. Building on the formal tools and theories developed by social network analysis, we examine the network organisation of 136 large traders in two border regions between Niger, Nigeria and Benin. In a business environment where transaction costs are extremely high, we find that decentralised networks are well adapted to the various uncertainties induced by long-distance trade. We also find that long-distance trade relies both on the trust and cooperation shared among local traders, and on the distant ties developed with foreign partners from a different origin, religion or culture. Studying the spatial structure of trade networks, we find that in those markets where trade is recent and where most of the traders are not native of the region, national borders are likely to exert a greater influence than in those regions where trade has pre-colonial roots. Combining formal network analysis and ethnographic studies, we argue, can make a significant contribution to the current revival of interest in cross-border trade in the policy field. 相似文献
