Particle size analysis of soils under simulated scene of crime conditions: the interest of multivariate analyses

Two simulated scenes of crime have been studied. Soil traces adhering to boots, sport shoes and tissues have been compared with control samples using particle size analysis. Comparisons of percentage of particles per class interval and multivariate analyses were used to determine how the size distribution of each suspect sample varied compared to the original distribution. A loss of coarse fractions characterized most of the suspect samples even though they were derived from soils having different distributional patterns. However, the differences between control and suspect samples were found to be more important for soils dominated by extreme size classes than for soils rich in medium size particles. The differences among soil samples from the same source were found to be restricted to the extreme size classes. The finding of significant differences within size classes ranging from 1 to 0.063 mm should be then considered as a dissimilarity sign between trace sample and hypothetic control soil.     

Sexual Violence Against Women Through the Lens of Environmental Criminology: Toward the Accumulation of Evidence-based Knowledge and Crime Prevention

Sexual violence against women is a serious problem worldwide. In this study, we organize and critically review previous empirical studies on sexual offenses against women through the lens of environmental criminology. For this purpose, we use the questions asked by environmental criminologists/crime analysts in the study of crime events; that is the: who, what, where, when, and how this phenomenon typically occurs. Based on the current state of the criminological research literature, we then provide a discussion on the prevention of sexual offenses against women drawing on a situational crime prevention framework. By engaging in this exercise, we argue that environmental criminology can substantially contribute to understanding and informing prevention practices in the field of sexual offenses against women.     

French nuclear idiosyncrasy: how it affects French nuclear policies towards the United Arab Emirates and Iran

This article elaborates the notion of ‘nuclear idiosyncrasy’ as a specific understanding of what nuclear weapons and energy are, what they stand for and what they can do. It then assesses the persistence of nuclear idiosyncrasy over time and its effects on French nuclear policies in the United Arab Emirates (UAE) and Iran. Based on interviews in France, Geneva and the UAE, this article contributes to three debates within foreign policy analysis and nuclear history. Is a regional approach necessary to understand the framing of foreign policies in the twenty-first century? Does a change in leadership fundamentally affect the orientations of nuclear policies? Are the risks of nuclear proliferation in the Middle East and the measures to prevent it similarly understood by all the players in the international community? First, it shows that French nuclear policies in the Middle East are not shaped by dynamics specific to the region as the often invoked notion of an ‘Arab policy of France’ would suggest. Secondly, in-depth analysis leads one to reject the idea of a major change between the nuclear policies of Presidents Chirac and Sarkozy. Thirdly, persistent French nuclear idiosyncrasy leads also to rejection of the idea of convergence towards a shared understanding of the proliferation threat in the Middle East.     

Process Tracing in Public Administration: The Implications of Practitioner Insights for Methods of Inquiry

The field of public administration is often seen as a late adopter of cutting-edge research methods. Related disciplines like political science use more advanced research methods for single or small-n case studies including techniques like process tracing. Many elements of process tracing are analogous to investigations. To inform process tracing practices, political scientists looked at Sherlock Holmes novels. We draw on the experiences of a police inspector and a former soldier who worked with intelligence to offer insights on the implementation of process tracing, bridge the academic–practitioner gap, and increase the methodological rigor in public administration research.     

The Campaign Value of Incumbency: A New Solution to the Puzzle of Less Effective Incumbent Spending

A puzzle in research on campaign spending is that while expenditure is positively related to votes won, this effect is far more strongly, or even exclusively, enjoyed by challengers rather than by incumbents. We unearth a new explanation for the puzzle, focusing on the hidden, yet variable, campaign value of office perquisites which incumbents deploy in their campaigns to win votes. When these variable office benefits are unobserved, then the effect is to make observed incumbent spending less effective than spending by challengers. Using data from the 2002 Irish general election, where incumbency was assigned a variable campaign value and included in declared campaign spending, we are able to demonstrate this hidden incumbency effect and estimate its relationship to electoral success, in terms of overall votes, share of votes, and probability of winning a seat. Contrary to previous research showing ineffective incumbent spending, we find that when the campaign value of office is also measured, public office value “spending” is not only very effective in winning votes, but also seems to be more effective than regular incumbent spending.     

Modus operandi and situational aspects in adolescent sexual offenses against children: a further examination

The relationship between situational factors and the modus operandi of 103 adolescents involved in sexual offenses against children (12 years old or younger) is analyzed. Situational factors taken into account in this study are the location of the crime, the offender-victim relationship, and the presence of deviant sexual fantasies involving the victim prior to the offense. Modus operandi strategies were measured on the basis of participants' responses to Kaufman's Modus Operandi Questionnaire. Results indicate that modus operandi strategies are influenced by situational factors and that the offender's home, when no one else is home, is likely to be the place and the situation for adolescent offenders to adopt manipulative strategies. Suggestions are made regarding future modus operandi studies.     

Mujahideen Mobilization: Examining the Evolution of the Global Jihadist Movement’s Communicative Action Repertoire

Abstract

Drawing on Tilly’s notion of “repertoire of action,” this article shows how the evolution of the global jihadist movement’s communicative action repertoire has increased the potential resonance of its discourse. It foresees the construction of the global jihadist movement’s discourse of mobilization as the result of the evolution of its network of actors, the context in which its communications are undertaken, and its adaptation to new communication technologies. Accordingly, it argues that the decentralization of the global jihadist movement has led to a widening of its communicative action repertoire and a diversification of its discourse offering.
