Digital evidence from peer-to-peer networks

In this paper we examine the legal aspects of the forensic investigation of peer-to-peer networks. Organisations may encounter instances where employees have used peer-to-peer software for a variety of types of computer misuse including the dissemination of copyrighted materials or indecent images, or instances where peer-to-peer software has been involved in the transmission of malware for malicious or criminal purposes. In this paper we examine the process of the forensic investigation of peer-to-peer networks, and the issues relating to obtaining digital evidence from such peer-to-peer networks.     

A randomized controlled trial of different policing strategies at hot spots of violent crime

Focusing police efforts on “hot spots” has gained acceptance among researchers and practitioners. However, little rigorous evidence exists on the comparative effectiveness of different hot spots strategies. To address this gap, we randomly assigned 83 hot spots of violence in Jacksonville, Florida, to receive either a problem-oriented policing (POP) strategy, directed-saturation patrol, or a control condition for 90 days. We then examined crime in these areas during the intervention period and a 90-day post-intervention period. In sum, the use of POP was associated with a 33% reduction in “street violence” during the 90 days following the intervention. While not statistically significant, we also observed that POP was associated with other non-trivial reductions in violence and property crime during the post-intervention period. In contrast, we did not detect statistically significant crime reductions for the directed-saturation patrol group, though there were non-significant declines in crime in these areas during the intervention period. Tests for displacement or a diffusion of benefits provided indications that violence was displaced to areas near the POP locations, though some patterns in the data suggest this may have been due to the effects of POP on crime reporting by citizens in nearby areas. We conclude by discussing the study’s limitations and the implications of the findings for efforts to refine hot spots policing.     

The Challenges of Moving into Middle Management: Responses from Police Officers

The role of the middle manager is crucial to a police organization. Despite this, little research exists concerning the characteristics of effective police managers, or the role that the promotional process and/or training plays in identifying and developing effective managers. To examine these issues, 328 Canadian police officers were surveyed and interviews were conducted with an additional 50 police professionals. The results highlight: (1) the importance of management in achieving organizational goals, (2) key characteristics of effective managers and common mistakes managers make, and (3) concerns surrounding the promotional process and the lack of managerial training. The implications of these findings are discussed.     

Bill Passage Speed in the US House: A Test of a Vote Buying Model of the Legislative Process

This article constitutes a test of central tenets of vote buying theories using data on the number of days it takes to pass important bills in the US House. Survival analyses of a model of bill passage length provide confirmatory evidence of vote buying by presidents and the congressional leadership. Bills that attract buyers of votes to maintain the status quo are shown to pass more quickly than those that do not. Bills on the president's agenda and those that are relatively close to members' ideal points also pass quickly. The analyses furnish some interesting insights into possible efforts to make the legislative process quicker.     

Research Note: Hassan al-Turabi,Osama bin Laden,and Al Qaeda in Sudan

This research note explores the events and circumstances surrounding Osama bin Laden's stay in Sudan from 1991 to 1996. In particular, it discusses the role that the Sudanese politician, Hassan al-Turabi may have played in the development of bin Laden and al Qaeda. It draws particular attention to the role of the Popular Arab and Islamic Congress (PAIC) in the emergence of a distinctive form of Radical Islam and offers a preliminary discussion of the emergence of particular qualities of al Qaeda ideology.     

The Radicalization of Homegrown Jihadists: A Review of Theoretical Models and Social Psychological Evidence

This article attempts to consolidate theorizing about the radicalization of Western homegrown jihadists. Five major models of radicalization are reviewed. The commonalities and discrepancies among these models are identified and analyzed in the context of empirical evidence in the field of terrorism research and social psychology. Three psychological factors emerge as contributors to radicalization: group relative deprivation, identity conflicts, and personality characteristics. Avenues for future research concerning the radicalization of homegrown jihadists are suggested, focusing on research that may not only be practical for counter-terrorism, but also feasible given the challenges of research with radicalized individuals.     

Book reviews

The article attempts to model structural adjustment patterns in a single, middle‐income oil exporter, Mexico. It explores the economy‐wide costs, in terms of economic growth, income inequality and poverty, of Mexico's economic stabilisation policies of the 1980s. On the basis of counterf actual simulation, it also explores the likely impacts of alternative adjustment strategies. This analysis utilises a modified Social Accounting Matrix (SAM) approach designed to overcome one of the major shortcomings of the conventional SAM: the assumption of unitary expenditure elasticities in household accounts. The base model is calibrated to track the overall and sectoral growth performance of the Mexican economy from 1980 to 1986 and becomes the foundation upon which our policy experiments are built. The article is part of an on‐going study of economy‐wide impacts of alternative structural adjustment policies in Mexico [Adelman and Taylor, 1990], and proceeds as follows: the SAM framework and estimated SAM are described in parts I and II; part III presents the base SAM model solution for 1980 to 1986; part IV presents the results of the policy experiments; and the conclusions are summarised in part V.     

Globalisation studies and the developing world: making international political economy truly global

For all the rhetoric surrounding globalisation, its meaning remains both vague and elusive and symbolises a host of different things to different people. In the main, however, most studies are marked by a restricted theoretical and empirical base, which precludes such studies from being truly global. They are generally predicated on selected examples from the core, with an occasional nod in the direction of experiences outside the familiar. While there are sporadic references to Asia and Latin America (invariably in the context of collapsing currencies and capital flight) there is almost no mention at all of Africa, South Asia, the Pacific region or Central Asia. That this neglect impoverishes the discipline of International Political Economy (ipe) is self-evident. It is argued that an ipe that is comparative by nature and takes into account the multi-variegated nature by which globalisation affects the global political economy, in particular recognising that the developing world has been, to a large extent, left out of the debate, is required if we are to make ipe truly global in scope.     

Policy making/implementing activities of elected county executives and appointed county administrators: Does form of government make a difference?

This article undertakes a comparative analysis of the policy making/implementing behavior of elected county executives and appointed county administrators. While both sets of actors are engaged considerably in the policy making and implementing processes, the manner in which they undertake these activities varies, suggesting that form of government and method of (s)election do make a difference in how counties are governed.
