Considering the steady and rapid growth of product counterfeiting and the damage it causes to society, it is important for criminology and criminal justice scholars to assist criminal justice officials, industry practitioners, and law makers in understanding the product counterfeiting problem and developing strategies to combat it. However, for researchers to be effective in their advisory role they must first establish what is known about product counterfeiting. As a first step in this process, we investigated relevant published research through a content analysis of 47 articles discussing product counterfeiting published in criminal justice and criminology journals through 2014. We analyzed various characteristics about the articles themselves, their authors, the journals they appeared in, and the nature and extent of their focus on product counterfeiting. We conclude this study with an evaluation of the state of product counterfeiting research and recommendations for future research.  相似文献

This article reflects on the turmoil in the states of the Levant, particularly seen in the context of broader tensions between Iran and Saudi Arabia. Particular regard is given to the radical challenge of Sunni and largely Salafi jihadism; the disabling of large parts of the Middle East state system in the wake of the Arab Spring; the dramatic fall in global energy prices; the fraying of traditional alliances between Saudi Arabia, the US and other powers. The increase in sectarianism and conflicts over authority in Islam are also discussed.  相似文献

The limits of the expert system, TrueAllele® Casework (TA), were explored using challenging mock casework profiles that included 17 single‐source and 18 two‐, 15 three‐ and 7 four‐person DNA mixtures. The sensitivity (ability to detect a minor contributor) of the TA analysis process was examined by challenging the system with mixture DNA samples that exhibited allelic and locus dropout and other stochastic effects. The specificity (ability to exclude nondonors) was rigorously tested by interrogating TA derived genotypes with 100 nondonor profiles. The accuracy with which TA estimated mixture weights of contributors to the two‐person mixtures was examined. Finally, first‐degree relatives of donors were used to assess the ability of the system to exclude close relatives. TA demonstrated great accuracy, sensitivity, and specificity. TA correctly assigned mixture weights and excluded nearly all first‐degree relatives. This study demonstrates the analysis power of the TrueAllele® Casework system.  相似文献
