Making environmental criminology smarter – A framework for directly measuring routine activities using passively collected geolocation data
We propose novel methods for analysing spatio-temporal tracking data collected via smartphones with the purpose of exploring the extent to which foundational, but as yet untested, assumptions within environmental criminology are observed in real-world behaviour. We provide systematic and replicable methods for identifying and quantifying nodes, trips, visits, paths and activity spaces – key elements of human mobility which underpin the vast major…
Seeking to quantify contributions that fisheries operations can make to a global Nature Positive goal
Amidst global efforts to address biodiversity loss, the concept of ‘Nature Positive’ has gained traction as a societal goal aligned with the Global Biodiversity Framework (GBF). While the goal is increasingly being embraced by governments and various business sectors, there has been little investigation into how fisheries, a key sector in the global economy and a major driver of marine biodiversity loss, could go beyond ‘sustainable fishing’ to c…
Literary Figures and International Thought
How may literary figures contribute to international thought? This article addresses this question using the previously neglected yet archetypal case of novelist and poet Thomas Hardy, who pioneered the term ‘international thought’ in the early 20th century. In its analysis of the Hardy case, the article offers a framework elucidating how literary figures may contribute to international thought not only through direct theoretical and conceptual a…

Can harm be predicted? On the development and validation of a statistical model for predicting harm in missing person incidents
Exploring criminal specialisation in co-offending groups
Researchers have studied criminal specialisation at the offenders’ level to understand criminal careers. Despite criminal careers comprising events in which offenders co-offend with others, we know less about the extent of co-offending groups showing signs of becoming specialists. To start addressing this gap, in this study we report a method through which we identified 1,796 co-offending groups in a network containing information about adult off…
Understanding the role of street network configurations in the placement of illegitimately operating facilities
The role of street networks in shaping the spatial distribution of crime has become a foundational component within environmental criminology. Most studies, however, have focused on opportunistic crime types, such as property offenses. In this study, we instead research a theoretically distinct phenomenon by examining the placement of venues that host criminal activity. In particular, we study the relationship between network structure and the pl…
Further evidence on the extent and time course of repeat missing incidents involving children
This study examines the extent and time course of repeat missing incidents involving children. Using data from one UK police force (n = 2,251), we find (1) that the majority (65%) of missing incidents are repeats, (2) that a small group of repeatedly missing children (n = 43; 6%) account for a sizable proportion of all missing incidents (n=739, 33%) and (3) that the likelihood of a child going missing repeatedly is elevated in the weeks immediate…
Offending with the accomplices of my accomplices
We measured triadic closure in co-offending networks - i.e., the tendency of two individuals to co-offend if they share an accomplice - using a method that addresses the risk of overestimating clustering coefficients when using one-mode projections. We also assess the statistical significance of clustering coefficients using null models. The data relates to adult offenders (N = 274,689) connected to criminal investigations (N = 286,591) in Colomb…
Routledge Handbook of NGOs and International Relations
"Offering insights from pioneering new perspectives in addition to well-established traditions of research and pioneering new perspectives, this Handbook considers the activities not only of advocacy groups in the environmental, feminist, human rights, humanitarian, and peace sectors, but also the array of religious, professional, and business associations that make up the wider Non-Governmental Organisation (NGO) community. Including perspective…
Spatial interaction and security
Sir Alan Wilson's ideas have been highly influential in the modelling of phenomena including migration, transport and economics. Latterly, research has explored the application of similar ideas to new problems at larger scales. Many of these studies relate to global challenges with significant policy implications. Here, we present an example in the form of original empirical work concerning forced migration associated with the current Syrian refu…
Patterns in the supply and demand of urban policing at the street segment level
Policing plays a critical role in crime prevention, incorporating both deterrent and responsive activities. Since many policing activities require the physical presence of officers, a crucial issue for police effectiveness concerns the extent to which officers are located where they are needed. Operationally, this can be framed as a ‘supply and demand’ issue, where the aim is to match the supply of police resource to the demand for service. In th…
Street Networks and Crime
Street networks are the primary structures around which urban areas are arranged. Perhaps more significantly, though, the network acts as a substrate for movement, and defines the paths that can be taken between locations. It therefore determines, among other things, how far places are from each other, and the extent to which different features will be used in the course of movement activity. In this way, street networks play a key role in shapin…
Street Network Structure and Crime Risk
Street networks shape day‐to‐day activities in complex ways, dictating where, when, and in what contexts potential victims, offenders, and crime preventers interact with one another. Identifying generalizable principles of such influence offers considerable utility to theorists, policy makers, and practitioners. Unfortunately, key difficulties associated with the observation of these interactions, and control of the settings within which they tak…
Examining the Relationship Between Road Structure and Burglary Risk Via Quantitative Network Analysis
Objectives To test the hypothesis that the spatial distribution of residential burglary is shaped by the configuration of the street network, as predicted by, for example, crime pattern theory. In particular, the study examines whether burglary risk is higher on street segments with higher usage potential. Methods Residential burglary data for Birmingham (UK) are examined at the street segment level using a hierarchical linear model. Estimates of…
Application of an entropy maximizing and dynamics model for understanding settlement structure
We present a spatial interaction entropy maximizing and structural dynamics model of settlements from the Middle Bronze (MBA) and Iron Ages (IA) in the Khabur Triangle (KT) region within Syria. The model addresses factors that make locations attractive for trade and settlement, affecting settlement growth and change. We explore why some sites become relatively major settlements, while others diminish in the periods discussed. We assess how politi…
Climate change and drought
Climate change is likely to increase drought risk during the 21 st century in many parts of the world. Climate model projections, under a range of emissions scenarios, consistently show that seasonal rainfall is likely to decrease across large parts of southern Europe, north Africa, central Asia and southern Africa, and reductions are also possible in other dry parts of the world. The effects of climate change, however, will be superimposed on th…
