Reliability of a two-dimensional footprint measurement approach

Although footprint evidence can be taken from the scene of a crime, the science underpinning such measurement in forensic science has not been fully explored.A literature search revealed various measuring approaches, all of which demonstrated either little or no measurement rigour in terms of reliability. The aim of this study was to apply a robust measurement approach for testing the reliability of two-dimensional footprint impressions.Three dynamic and three static footprints were taken from the right foot of thirty female and thirty one male volunteers using the ‘Inkless Shoeprint Kit’. The images were digitised. Lengths, widths and angles were measured using a selection of currently employed methods.An investigation of the reliability of the chosen measuring method suggested high intra-rater agreement: for example, the length measurement suggested an intraclass correlation coefficient (ICC) 0.99, 95% Confidence Interval (CI) ? 0.28 to 0.01, standard error of measurement (SEM) 0.07, Limits of Agreement (LOA) ? 0.91 to 0.65.Inter-rater reliability between three operators was also high: SEM ranged from 0.05 mm to 0.07 mm, ICC 0.99.Our study has established a reliable two-dimensional measuring technique that could be used for footprint comparison in further research.     

Meta Risk Management and Responsive Regulation for Tax System Integrity

Risk society and reflexivity as themes in contemporary sociology are brought together in a concrete way in the concept of meta risk management. Two case studies of the risk management of corporate risk management systems by the Australian Taxation Office are used to argue that meta risk management can be a cost-effective and responsive regulatory strategy, at least in the context of a complex risk environment such as business taxation. Meta risk management is a promising strategy when risks are volatile and difficult for the regulator tocomprehend when the risks are effectively under the control of an organization over which the regulator has leverage.     

Thatcherism and the Conservative Party

Neither spatial models of party competition nor the 'Westminster' model of British politics explain the phenomenon of Thatcherism. One explanation of its success, examined by Crewe and Searing, suggests that Mrs Thatcher sought to convert the Conservative party and the wider electorate to her distinctive brand of liberal Whiggism and traditional Toryism. They found little evidence of the success of this, however, among the British electorate as a whole. In this paper, data from the first national survey of Conservative party members demonstrates that she had little success in converting the Conservative party to these ideas either, although she did have a secure ideological base within the party. The results also suggest that her successor, John Major, has a rather different support base within the party from that of Mrs Thatcher. The implications of these findings for spatial models of party competition and the Westminster model of British politics are discussed.     

Mass Political Behaviour: Is There More to Learn?

Research progress in voting studies and party competition, the mass media, work on social movements, interest groups and collective action, is reviewed for the last decade. Theoretical impetus in applied work seems weak in British studies; sub-fields of research are being pursued in isolation. In electoral studies at least there are signs of over-specialization and loss of valuable interconnections with the mainstream of political science. A number of pathways for improving the state of the art are identified, focusing on a renewal of theoretical input, the correction of some 'system biases', greater methodological pluralism and more integration of demand-side and supply-side studies.     

Emergency relief programmes for pastoral communities

This article makes the case that emergency relief programmes in pastoral areas of Africa do little to relieve the fundamental effect of famine, which is destitution. It argues that traditional mechanisms of coping with drought are often disrupted by food-aid programmes, especially Food-For-Work. Three case studies from Sudan and Kenya are used to support the argument. The article concludes by making policy recommendations for emergency programmes to be more effective in meeting the primary need of pastoralists following severe drought, which is to rebuild herds and therefore their livelihoods.     

Intergovernmental grants and successful tax limitation referenda

Analyses of fiscal limitation referenda have typically ignored the role of institutional structure in referenda outcomes. This article demonstrates the importance of such structure through the investigation of intergovernmental grants in a model of federal tax rate determination. Tax limitation referenda are shown to depend upon both the use of tax rates as a grant disbursement criterion as well as the size of the proposed tax cut.     

Rent-seeking and X-inefficiency

This paper discusses the social cost of monopoly with special attention given to the geometric representation of that social cost, notably rent-seeking and X-inefficiency. The possibility of an overlap between these two measures is examined. In particular the paper addresses a problem of measure identification which highlights the need to reconsider the normative microfoundations of rent-seeking.     

Postmortem analysis of anastomotic suture line disruption following carotid endarterectomy

The tensile strength of a surgical suture is essential in maintaining the integrity of vascular anastomoses. While faulty operative technique and the loading strength of individual sutures have been implicated in spontaneous suture line disruptions, there has, to date, never been a published postmortem analysis of a suture that has known to have failed. We present the case of suture line disruption leading to fatal exsanguination in a 77-year-old man following carotid endarterectomy with a facial vein patch. Using both dissecting and scanning electron microscopy, we determined that surgical technique (an untied knot) was the cause of the suture line disruption. The removal of a broken or untied suture at surgery or at autopsy should not preclude proper analysis of the failed suture, because the results can have both medico-legal and public health implications.     

Forensic applications of chemical imaging: latent fingerprint detection using visible absorption and luminescence

Chemical imaging technology is a rapid examination technique that combines molecular spectroscopy and digital imaging, providing information on morphology, composition, structure, and concentration of a material. Among many other applications, chemical imaging offers an array of novel analytical testing methods, which limits sample preparation and provides high-quality imaging data essential in the detection of latent fingerprints. Luminescence chemical imaging and visible absorbance chemical imaging have been successfully applied to ninhydrin, DFO, cyanoacrylate, and luminescent dye-treated latent fingerprints, demonstrating the potential of this technology to aid forensic investigations. In addition, visible absorption chemical imaging has been applied successfully to visualize untreated latent fingerprints.
