Where, when and how is crime committed?

One of the key questions of NSCR research focuses on where, when and how crimes are committed. Why does crime concentrate in certain locations rather than in others? Is it because offenders happen to know these locations, as they are close to their home, job or (previous) school? Data from crime scenes and activity patterns of perpetrators and victims provide insight into the underlying choice behaviour of perpetrators.

We investigate the way in which crimes are committed and in which situational context: are bystanders and law enforcement officers present and do they have an (active) role? Carefully studying and analysing CCTV footage is a game changer for the study of crime. Researchers see real-time how situations unfold and can thus study and unravel the behaviour of perpetrators, victims and bystanders.

How do people decide who to intervene towards in street conflicts?

Imagine that you are walking down a street and two individuals start to fight. Many of us want to believe that we would intervene and help in this kind of situation. But helping can be challenging – fights are often fast paced and can appear chaotic. There is oftentimes not a clear division between who […]

Securing Protected Areas: The Decision-making of Poachers and Rangers

Despite considerable effort to reduce the harm, poaching continues to be a serious threat to many wildlife populations around the world. Strong and robust security of protected areas is an essential element of long term conservation success. Formal law enforcement, such as rangers patrolling a protected area, is a common security strategy used to detect […]

Growing up in a single-parent family increases the risk of criminal behaviour during adolescence

In the European Union and the United States 15 and 27% of children, respectively, grow up in a single-parent family. Although the proportion of single-parent families has remained stable in recent decades, a clear shift is visible in how single-parent families come into being: this happens more often due to a divorce or with the […]

Short intensive course: Systematic Video Observation and Analysis of Human Conflict

Systematic video observation is a methodology developed as a joint venture of scholars from criminology, anthropology, psychology, ethology, and sociology over the last five years. The course is therefore also set up as a joint venture between the scholars that have been involved in this development. They will take on the role of instructors in […]

NWO-Veni and two NWO-Vidi’s for NSCR researchers and fellows

Veni | Choosing the good side: factors that lead to non-criminal hacking Dr Marleen Weulen Kranenbarg | VU University Amsterdam | Fellow NSCR Cybercrime In contrast to criminal hackers, non-criminal hackers actively help in securing IT-systems. By examining lifecourse characteristics of non-criminal hackers, as well as situational and cultural factors, this study will show why […]

Compliance, busyness and social distancing during the requirement to wear a face mask

By analysing images from security cameras in the face mask areas before and after the requirement to wear face masks and comparing these with areas where there was no such requirement, people’s behaviour could be accurately described. The research examined the wearing of face masks, busyness and changes in busyness, and compliance with the 1.5 […]

Marie Rosenkrantz Lindegaard professor by special appointment of Dynamics of Crime and Violence

How do crime and violence develop in sequences of interactions? What do people do if they become involved in such interactions and how can we understand and explain their behaviours? What are the consequences of their actions for the safety of all those involved and how can crime and violence be managed and controlled? These […]

Scientifically strengthen police research and practice

The research program is in line with the Strategic Research Agenda for the Police, and examines how police action works, in what circumstances those action work, for whom, and by whom it works. NSCR uses advanced scientific methods and the latest, current insights and theories, applied to the Dutch context. The program takes research into […]

Real-life observations of social distance in public: do people actually do it?

Rosenkrantz Lindegaard and Snoek draw on full time recordings of 55 surveillance cameras in Amsterdam to identify hotspots for rule-breaking of the social distancing measures. For their analysis, they apply video artificial intelligence and systematic behavioral coding, in order to establish where in the city people tend to break the rules, e.g. gather in groups […]
