Hair-MAP: a prototype automated system for forensic hair comparison and analysis

This paper demonstrates the feasibility of the automation of forensic hair analysis and comparison task using neural network explanation systems (NNESs). Our system takes as input microscopic images of two hairs and produces a classification decision as to whether or not the hairs came from the same person. Hair images were captured using a NEXTDimension video board in a NEXTDimension color turbo computer, connected to a video camera. Image processing was done on an SGI indigo workstation. Each image is segmented into a number of pieces appropriate for classification of different features. A variety of image processing techniques are used to enhance this information. Use of wavelet analysis and the Haralick texture algorithm to pre-process data has allowed us to compress large amounts of data into smaller, yet representative data. Neural networks are then used for feature classification. Finally, statistical tests determine the degree of match between the resulting collection of hair feature vectors. An important issue in automation of any task in criminal investigations is the reliability and understandability of the resulting system. To address this concern, we have developed methods to facilitate explanation of neural network's behavior using a decision tree. The system was able to achieve a performance of 83% hair match accuracy, using 5 of the 21 morphological characteristics used by experts. This shows promise for the usefulness of a fuller scale system. While an automated system would not replace the expert, it would make the task easier by providing a means for pre-processing the large amount of data with which the expert must contend.     

Measuring media oriented terrorism

Although long established, media oriented terrorist events have not been conceptualized or measured in a coherent manner. To forward the empirical study of media oriented terrorism, a measure that can be applied to terrorist events or to terrorist groups was developed and employed to compare terrorist activity for twenty terrorist groups and two hundred terrorist events. The media orientation measure taps into five factors of media orientation and successfully differentiates high from low media orientated events and active and inactive media oriented terrorist groups. The single most important factor regarding any group's individual media orientation level was their base of operation. Terrorist groups that were engaged in regional struggles were found to be less media oriented. Despite the news value of death and injury, the terrorist group with the highest fatality and injury averages ranked ninth in its media orientation score indicating that death and injury was not a necessary indicator of media orientation. Scores further suggest that media savvy well-known terrorist groups did not pursue media oriented activity as a constant strategy.     

Detecting Specialization in Offending: Comparing Analytic Approaches

Offending specialization continues to be a subject of empirical inquiry for scholars interested in criminal careers. Early research consistently spoke to the generality of offending profiles, but more recent work has revealed somewhat mixed findings. These results have emerged alongside newly developed and applied methods that detect and describe offending specialization. To what extent these methods shape divergent conclusions and/or provide overlapping insight remains unclear, however. Therefore, the degree to which more recent inquiries are actually studying the same operational definition of specialization is unknown. In order to consider this issue further, this study utilizes four frequently applied approaches with a single data set. The study indicates when and where findings converge and also describes any unique insights provided by each method. The work concludes with a discussion surrounding the utility of applying multiple strategies in assessing specialization in criminal offending.     

United States Hegemony and Globalisation: What Role for Theories of Imperialism?

This article examines the return of the subject of imperialism to the social sciences since 2001, focusing in particular on Marxist and Marxist-related attempts to reconstruct an analysis of the US-led international order based on this concept. It does so by first examining attempts to update Marxist and Marxian work to understand contemporary globalisation, and then points to both the weaknesses of these approaches and international events that have undermined these theories. The paper then examines the return of imperialism in some detail. While the international order can still be described as imperialist, the article is sceptical of many accounts of the ‘new imperialism’. This is partly because the utility of classical theories was questionable in the pre-1914 era, and are even more so now. Theorising imperialism in turns of surplus capital or a spatial fix ignores the direction of capital flows, both before the First World War, and in the current era. Moreover, as Marxist and Marxian theories of globalisation point out, the current era is one of greater openness and international integration than the pre-1914 era, and there is far greater cooperation between the core capitalist states, as well as sovereign states in the developing world. Contemporary imperialism is characterised by US hegemony but also greater global interdependence, and US military domination does not guarantee its economic domination. At the same time however, US hegemony is closely related to neo-liberalism and, despite as much as because of US intentions, these same policies undermine the prospects for development in the ‘South’. In this respect, US attempts to ‘Americanise’ the world are undermined by US hegemony and the imperialism of free trade.     

Insecure peace: understanding citizen and local government relations in a Maoist-affected region in India

This paper examines emerging citizen and local government relations in a village in the Junglemahal region of the state of West Bengal, once a major bastion of the Maoist insurgency in India. Since 2014, Junglemahal has not experienced a single Maoist-related incident. This has been widely attributed to the West Bengal government’s “model” handling of the insurgency, which rests on the rapid mobilization of public services through the non-elected arms of local governments, bypassing elected officials. How have Junglemahal’s residents experienced this particular form of post-conflict governance? Drawing on the culture-centered approach that ethnographically observes the processes of identifying development problems and developing community-grounded solutions to these problems, our findings indicate that the hyper-developmental state was paradoxically experienced by our respondents as a very distant entity. A recurrent theme in our interviews is the absence of a locally embedded party leadership that could be approached regarding issues of distributive justice. We argue that this desire for party mediation in public service delivery is an expression of a powerful social norm that has survived the conflict and ought to be integrated into post-conflict governance structures if the current peace is to endure.     

Risk aversion and rent-seeking: An extension and some experimental evidence

Theoretical investigations indicate that the risk attitudes of individuals will effect the amount of rent that can be assumed to be dissipated by rent-seeking activities. Following this line of investigation we extend Hillman and Katz's work to a small numbers case and demonstrate that the degree to which a monopoly rent is dissipated is dependent upon the structure of the risk attitudes of two risk averse individuals.Our earlier laboratory results were evaluated with respect to the risk neutral Cournot-Nash predictions. However, given the uncertainty present in the rent-seeking experiment, our ability to reject these risk neutral predictions may not be, in fact, a failure for the model but a result of risk aversion. In laboratory experiments in which we control for the relative risk attitudes of individual agents, we show that risk aversion matters. The relative risk aversion of individuals affects the level of rent-seeking activity and the extent to which rents are dissipated. In our experiments, the relatively less risk averse individuals dissipated relatively more rent.
