Automatic forensic face recognition from digital images.

Digital image evidence is now widely available from criminal investigations and surveillance operations, often captured by security and surveillance CCTV. This has resulted in a growing demand from law enforcement agencies for automatic person-recognition based on image data. In forensic science, a fundamental requirement for such automatic face recognition is to evaluate the weight that can justifiably be attached to this recognition evidence in a scientific framework. This paper describes a pilot study carried out by the Forensic Science Service (UK) which explores the use of digital facial images in forensic investigation. For the purpose of the experiment a specific software package was chosen (Image Metrics Optasia). The paper does not describe the techniques used by the software to reach its decision of probabilistic matches to facial images, but accepts the output of the software as though it were a 'black box'. In this way, the paper lays a foundation for how face recognition systems can be compared in a forensic framework. The aim of the paper is to explore how reliably and under what conditions digital facial images can be presented in evidence.     

New methods for examining expertise in burglars in natural and simulated environments: preliminary findings

Expertise literature in mainstream cognitive psychology is rarely applied to criminal behaviour. Yet, if closely scrutinised, examples of the characteristics of expertise can be identified in many studies examining the cognitive processes of offenders, especially regarding residential burglary. We evaluated two new methodologies that might improve our understanding of cognitive processing in offenders through empirically observing offending behaviour and decision-making in a free-responding environment. We tested hypotheses regarding expertise in burglars in a small, exploratory study observing the behaviour of ‘expert’ offenders (ex-burglars) and novices (students) in a real and in a simulated environment. Both samples undertook a mock burglary in a real house and in a simulated house on a computer. Both environments elicited notably different behaviours between the experts and the novices with experts demonstrating superior skill. This was seen in: more time spent in high value areas; fewer and more valuable items stolen; and more systematic routes taken around the environments. The findings are encouraging and provide support for the development of these observational methods to examine offender cognitive processing and behaviour.     

Civilization: “It Means Just What I Choose It to Mean”

Civilization is a complex and powerful word and idea that should neither be reviled nor revered, but it should be respected. It is said that the idea of civilization can be used simply to describe; but as a binary term, the ideal of civilization can be used to both to describe and evaluate; or pass judgement in the very act of describing. The nature of such concepts is that they can be used to either commend or condemn the actions or peoples they are used to describe.     

Negotiating Liberty: The Use of Political Opportunities and Civil Society by Barbary State Captives and Guantánamo Bay Detainees

This article contrasts two distinct sets of prisoners who were held by foreign governments: sailors from the United States held captive in Algiers in the late‐eighteenth century and British citizens detained in Guantánamo Bay in the early‐twenty‐first century. The article uses social movement theory to examine and compare the campaigns orchestrated by these men and their supporters, and the role of those campaigns in securing their freedom. It demonstrates the utility of social movement theory in comparing cases of foreign detention that transcend centuries, regions and communication technologies. We find that successful campaigns on behalf of citizens held captive abroad, and the timeline of those successes, are contingent on the exploitation of domestic political opportunities and an external event to trigger government action on behalf of the captives.     

Perceptions of Time and Their Impact on Negotiations in the Arabic-Speaking Islamic World

This article examines how perceptions of time affect Arabic-speaking Islamic negotiators and how their attitudes about time, and their corresponding behaviors, may differ from those of their Western counterparts. We begin by identifying cultural differences in the conceptualization of time and then comment on the role of time in negotiations, discussing how time influences bargaining, trust, and negotiation tactics. In the section on tactics, we discuss stall-and-delay tactics, the use of the past as an objective standard, and limits on negotiating the future. Our purpose is to encourage negotiators from the West to be knowledgeable about the way they, as well as negotiators from Arabic-speaking Islamic cultures, conceive of and use time in negotiations. We believe that understanding that the very concept of time is often quite different in these two cultures is an important step in facilitating negotiations that cross these cultural boundaries.     

Residential Community Associations and the American Intergovernmental System

Despite their growth and functional similarity to census-listedgovernments, residential community associations (RCAs) representa little-researched feature of American federalism. This studyemploys survey data from a national sample of RCAs to examinehow these organizations relate to other parts of local governmentsystems. The findings underscore the similarity of RCAs to localgovernment with regard to service provision, intergovernmentalcontracting, and lobbying with other units. Multivariate analysisshows that where RCAs are overlapped by other local units, includingother RCAs, they engage in more government-like actions. Thearticle also seeks to stimulate further research on RCAs byreflecting on measurement issues and the federalism implicationsof the study's findings.
