Inter-observer error for area of origin analysis using FARO Zone 3D

In a bloodletting incident, the area of origin (AO) of an impact bloodstain pattern is crucial when establishing the sequence of events. The use of laser scanners and other three-dimensional (3D) technologies to document and analyse bloodstains have been the subject of previous papers, especially where AO analysis is concerned. FARO Zone 3D (FZ3D) is a relatively new software programme that can be used for bloodstain AO analysis. FZ3D requires a greater understanding of inter-observer errors associated with AO. This study looked at the inter-observer variation between 21 examiners when repeatedly calculating the AO six times for a single impact pattern on a plain white wall. An impact rig which consisted of a spring tension arm was positioned and fixed 45 cm from the X wall (right wall), and 45 cm from the Y wall (left wall). This experimental design resembles an impact blow for a bloodletting event. The AO was unknown to all examiners, making it a blind study. The collected results were documented in a Microsoft Excel datasheet and later analysed. From previous literature, a 30 cm acceptable allowance was utilised for AO analysis; however, there is currently no accepted standard error for this type of analysis. The overall total 3D mean error for all examiners was 5.62 cm. The maximum error for any one impact analysis was 24.27 cm. The variation of the data, which was collected by all examiners, was documented as X = 1.14 cm, Y = 1.24 cm, Z = 1.68 cm, and the total 3D error = 2.28 cm. The total 3D error for any one examiner and the variance between examiners did not exceed the 30 cm acceptable allowance utilised in previous literature.     

Islam,Islamism, and Post‐Islamism: Rediscovering Politics after the War on Terror

Over the past twenty years, an influential body of conservative scholarship has focused on the alleged conflict between Islam and the West. Following widespread criticism of this scholarship, a number of commentators have revived its core assumptions to claim that the real conflict is between liberal democracy within Muslim societies and the political ideology of Islamism. In this article we trace the evolution of this scholarship, and suggest that recent empirical developments in the Muslim world suggest the potential for post‐Islamist parties to successfully adapt to the demands of democratic competition within Muslim societies. In this context, the emerging conflict is not between Islam and the West, or Islamism and the West, but between two very different discursive practices within the Muslim world that invoke Islam for radically different purposes. A traveler enters the world into which he travels, but a tourist brings his own world with him and never sees the one he's in. ¹      

Changes in staff confidence and attributions for challenging behaviour after training in positive behavioural support within a forensic medium secure service

Positive behavioural support (PBS) is a non-aversive approach to preventing and managing challenging behaviours. Seventy-nine qualified and unqualified nursing, psychology and occupational therapy staff were trained in using PBS. To measure the effectiveness of the training, confidence in managing challenging behaviour and attributions for causality, control and stability were measured before and after the training. To measure confidence, an adapted version of the Confidence in Coping with Patient Aggression Instrument was used. Attributions were measured using the Challenging Behaviour Attributions Scale and the Causal Dimension Scale II. There was a significant increase in confidence after training. In addition, there were significant changes in attributions relating to causality and stability of challenging behaviour, particularly for qualified staff. The results suggest that confidence and attributions are affected positively by training in PBS within a medium secure forensic mental health setting.     

Comparative advertising and celebrity photographs--fair dealing under the CDPA 1988

Legal context. Legal context. This article reviews the conceptof ‘fair dealing’ under Copyright Designs and PatentsAct 1988, section 30. It does so in the context of to recentcases concerning the fair dealing defence, IPC Media Ltd v NewsGroup Newspapers Ltd and Fraser Woodward Ltd v BBC are considered. Key points. The traditional approach of courts to ‘fairdealing’ is based upon a number of ‘factors’considered relevant in determining whether a use of a copyrightwork is fair. The article argues that there are a number ofproblems with this approach. In particular, it claims that theapproach is unsystematic and rests upon a number of questionableassumptions. It suggests that the decision of Hart J in IPCMedia Ltd demonstrates these problems to a very significantdegree. In contrast, that of Mann J in Fraser Woodward Ltd provideswelcome guidance on the application of the concept of fairnessin certain cases. Practical significance. The criticisms made in this articlehighlight a number of discrepancies in the existing case lawand suggest a need for closer consideration and greater disciplinein decision-making in this area.     

The future of self-determination and territorial integrity in the Asian Century

Abstract

The twentieth century saw the rise of two important and interrelated norms. The first is the norm of self-determination, which advances the right of stateless nations to govern themselves. The second is the norm of territorial integrity, which upholds the principle that political borders should be respected. A consequence of these norms has been an increase in secessionism, a decline in conquest, and a proliferation of states. This paper will examine the development of these norms, their interrelationship, and their prospects for the future. Attention will be given to three important questions: (1) Under what conditions does a norm endure beyond a power transition? (2) How likely is an ascendant China or India to support the norms? (3) What does a power transition and the corresponding support of these norms augur for the future of secession, conquest, and the number of sovereign states?
