“What works?” is only the beginning. To improve investigative interviewing, we also need to ask: how, for whom, under what conditions, and at what cost? Our paper explores how EMMIE can help bridge research and practice. Open-access at: doi.org/10.1080/1561...

Most procedural justice research has been cross-sectional—making causal claims difficult. Our longitudinal study asks whether police legitimacy reduces delinquency, or whether delinquency shapes legitimacy beliefs. The stronger evidence points to the latter. journals.sagepub.com/doi/10.1177/...

Do greater investigative efforts lead to better case outcomes? In a preregistered systematic review, we found many positive associations across 38 studies—but major variation in measurement and few rigorous causal designs. More evidence is needed on what works, how and why. doi.org/10.1108/PIJP...

🚨 It's been a long time in the making, but I'm happy it's finally out! Standing on the shoulders of giants, in this preprint we propose an avenue for theoretical development in the field of environmental (cyber)criminology with practical applications for crime analysis. bsky.app/profile/soca...
The title page of the preprint.

Title: The Topology of Cyberspace and Cybercrime Journeys: A Framework for Analyzing Online Offender Mobility

Authors: Asier Moneva, Stijn Ruiter, and Wim Bernasco

Abstract: This paper introduces a novel framework for analyzing online offender mobility. Drawing on multidisciplinary insights, we extend two established criminological models for studying offline offending—the geometry of crime and crime journeys—by adapting their core concepts to cyberspace and developing a topology in which the cyber place is defined and becomes the unit of analysis. Just as offenders travel before, during, and after committing crime offline, we argue they also undertake trips before, during, and after committing cybercrime, and that like offline journeys these cybercrime journeys comprise identifiable and measurable components. We further distinguish between human journeys (what offenders perceive) and data journeys (what happens to the information they transmit). We explicitly demonstrate how concepts from the geometry of crime and crime journeys translate from offline to online crime and mobility. This approach enables the systematic formulation of research questions and the measurement of behavioral patterns, facilitating the generation and accumulation of knowledge on cybercrime offending. The paper illustrates the framework’s theoretical relevance within environmental criminology and its practical application for cybercrime analysis through concrete examples.Schematic representation of a cybercrime journey. Hindu-Arabic numerals represent the sequence of cyber places visited by the user, while Roman numerals indicate the sequence of infrastructure nodes traversed by the data.
