Fundamental to any ballistic armour standard is the reference projectile that is to be defeated. Typically, for certification, consistency of bullets is assumed. Therefore, practical variations in bullet jacket dimensions can have far reaching consequences. Traditionally, internal dimensions could only be analysed by cutting bullets which rules out any subsequent ballistic assessment. Therefore, the use of a non-destructive X-ray computed tomography (CT) method is explored in this paper. A set of 10 bullets (9 mm DM11) was taken for analysing both intra and inter bullet jacket thickness variation. CT measurements of jacket thickness were validated with high resolution scanning electron microscope (SEM) images. An image based analysis methodology has been developed to extract the jacket thickness map and the centre of gravity. Thickness variations of the order of 200 μm were found commonly across all the bullets along the length and an angular variation of up to 100 μm was found in a few bullets. Jacket thickness and centre of gravity were also calculated for the same bullets after impact and the variations between the pre- and post-impacted bullets were compared, by establishing a common physical reference. The results show that the proposed CT scanning approach and subsequent image analysis method can bring out the statistical variations in bullet geometry pre- and post impact effectively.  相似文献

Identity fraud as a term and concept in its formative stages was often presumed to be identity theft and visa versa. However, identity theft is caused by the identities (or tokens) of individuals or organisations being stolen is an enabling precursor to identity fraud. The boundaries of identity fraud and identity theft are now better defined. The absence of specific identity crime legislation could be a cause of perpetrators not classified as breaching identity crimes but under other specific entrenched law such as benefit fraud, or credit card fraud. This metrics overlap can cause bias in crime management information systems. This study uses a multi-method approach where data was collected in both a quantitative and qualitative manner. These approaches are used as a lens for defining different classes of online identity crimes in a crime management (IS) security context. In doing so, we contribute to a deeper understanding of identity crime by specifically examining its hierarchical classes and definitions; to aid clearer structure in crime management IS. We seek to answer the questions: should current law around identity fraud continue to be reinforced and measures introduced to prevent identity crime; should laws be amended; or should new identity crime laws be constructed? We conclude and recommend a solution incorporating elements of all three.  相似文献

Deterrence lies at the heart of the criminal justice system and policy. There is a lack of information on citizen??s perceptions regarding a critical element of the deterrence process as it manifests through the communication of sanction threats. This study uses data from over 400 adults to examine their knowledge regarding the probability of detection and the average punishments for DUI, and also assesses the contribution of demographic and theoretical variables in predicting perceptions of detection probabilities and punishment estimates. Results show that persons over-estimate the likelihood of detection and provide higher estimates for average sentence lengths, but very few variables predict deterrence perceptions. An investigation of the resetting effect shows that persons tend to lower the estimated likelihood of punishment after experiencing a punishment. Deterrence may work better if researchers and policy officials understand what influences these perceptions and how they may be modified.  相似文献

The Curious Attraction of Wagner's Law   总被引:1,自引:0,他引:1  
Peacock  Alan  Scott  Alex 《Public Choice》2000,102(1-2):1-17
Wagner's ‘law of increasing state activity’ has recently been subjected to intensive use of recondite econometric testing procedures. An examination of the relevant articles reveals ignorance both of Wagner's definition of ‘state activity’ and of his insistence that he was not engaged in prediction. Consequently, the omission of public enterprises contained in Wagner's definition leads to a model misspecification and the object of testing his hypothesiss remains obscure.  相似文献

This article reports the first perceptual deterrence study of a sample of police officers. The study investigated the influence of traditional deterrence considerations, extralegal sanctions, and impulsivity on the intention to commit several hypothesized acts of police misconduct. The results were largely consistent with perceptual deterrence findings from samples of college students, experienced offenders, and corporate managers. In particular, this study found that both legal and extralegal sanction threats potentially deter police misconduct. Further, it found that impulsivity diminished the deterrent influence of both sanction forms. The study also found that some of the effects of the explanatory variables depended on whether officers had prior punishment experience. The article discusses the implications of its findings for combating police misconduct and for deterrence research generally.  相似文献

Well-being involves various levels: the individual, the institutional-distributive, and the societal. These levels are interrelated. Social indicators of well-being must be theoretically based so as to take into account these levels. A societal process model is proposed to describe the levels of society and the nature of well-being at each level. Social indicator types regarding the output and distribution of well-being, the effect of policy manipulatable and nonmanipulatable inputs, and the secondary consequences of inputs are suggested and examples are provided.The ideas presented herein have evolved from the authors' participation in a research project conducted for the U.S. Agency for International Development (AID/csd—3642), but do not necessarily reflect the views of that agency. Thanks are extended to J. Steven Picou, James Copp, Jon Alston, Bill Howard, and Ben Crouch, as well as to the then editor of this journal, Garry Brewer, and several anonymous reviewers who were kind enough to provide both cogent critique and encouragement.
