This article focuses on the ways the NVU, Pegida and Voorpost - three far-right groups from the Netherlands - make use of social media platforms in the year 2017. Our results show that these extreme right-wing groups use social media to spread their ideology, to construct a group identity, and to call for (democratic) forms of resistances. In addition, our findings illustrate that these far-right groups seem to adjust to their digital surroundings: they do not change or conceal their extremist ideas, but rather manage their online content to ensure that their ideologies can be disseminated through social media.

In our 2017 report “Profielen van outlaw bikers and outlawbiker clubs” we concluded, “Dutch members of outlaw motorcycle gangs disproportionally frequently have a history criminal justice contacts”. The attorney representing the Hells Angels in the civil law suit filed by the Dutch public prosecutor requesting a civil ban of the Hells Angels, after consulting an expert methodologist, challenged this conclusion due to the possibility of type 2 and type 1 errors in constructing our sample from a police gang database. Here we calculate the proportion of convicted Hells Angels members under different levels of potential bias resulting from these errors. We find that a realistic estimate of the proportion of convicted individuals among the Dutch Hells Angels membership is between 58-96%, which, at a minimum, is roughly twice that in an age-matched population of male motorcyclists who are not members of an outlaw motorcycle club.

This study describes the trend in victimization of homicide in the Netherlands in the period 1992-2016. Using data from the Dutch Homicide Monitor, the findings show that the homicide rate has been falling since the 1990s. This decrease is the greatest among male and female victims between the ages 20 and 39. This findings emphasize the importance of shifting the discussion about the general homicide drop to an in-depth analysis of gender and age of victims of homicide.

Recent studies show that neurocognitive functioning of people within the criminal justice system might be relevant for judicial intervention and reintegration programs, but the use of this information is hindered by – among other things – a lack of appropriate norm scores for neuropsychological tests. A total of 272 detainees completed the d2 attention and concentration test. This article shows that for the d2 attention and concentration test, the already available norm scores are not appropriate for the use within the criminal justice system. New norm scores for Dutch detainees are provided, based on outcomes of a regression based norm procedure. These norm scores are made freely available.

This contribution reflects on the criminological meaning of the still ongoing trend of digitalisation. What does this mean for crime as a phenomenon and for the explanation of criminal behaviour? Not only did we see the emergence of new types of offending, also the context of crime has changed. In principle, the underlying explanatory processes can remain the same, but their application in the online world is complex and deserves further attention. Online social interactions are not only important for online crime, but also for traditional offenses. However, systematic research on how this actually takes place is scarce.

If, as criminologists, we really want to contribute to solutions for the great challenges of our time, we should be…surfing more. In a dynamic environment full of contradictions, we should be constantly in motion, moving left and right between different theoretical-normative perspectives as well as between methodological perspectives. This paper clarifies that surfing movement with some illustrations. It then proposes three goals for a criminological research agenda that should help us address the great challenges: actual (as opposed to superficial) relevance for practice, causal ambitions and multidisciplinarity. The paper concludes with some reflections about the organization and funding of criminological research.

Two developments are discussed that have a significant influence on the scope and content of the penology of the future, but otherwise have little to do with each other: The expansion of the sentencing field has resulted in a completely fluid research field. However, the important questions of penology can only be answered by integrally mapping and analyzing that sentencing field. For that reason, penology should radically free itself of the limitation of its field of research to the penal sanction. Ongoing insight into the functioning of the brain and the predictability of behavior on the basis of algorithms shine a different light on the portraits of mankind on which we base punishment. It also exposes a range of new possibilities to influence behavior and prevent criminal behavior. It is also part of the research field of penology to question which of those possibilities we want to use and under which conditions.

In this contribution, I describe several key developments that have been fundamental to the development of criminology in the past 50 years. Next, I sketch the contours of several more recent developments, paying particular attention to three technologies, virtual reality, smartphones and wearables that will leave their imprint on the field. These developments will also imply a shift from the study of criminality to researching criminal behaviour.

Scenario techniques allow for dynamic explorations of possible futures. With the uncertainties about interdisciplinarity and the public role of criminology four scenarios for criminology in 2040 are presented. Crime Science and Criminal Policy describe situations which combine a strong public role for criminology to a low and high level of interdisciplinarity. Da Vinci and Theoretical Criminology portray futures with a limited public role for criminology and a high and low level of interdisciplinarity.

Forensic psychiatric treatment plays a mayor role in keeping society safe. However, the expectations about what can be achieved with forensic treatment do not seem to be realistic. This complicates the chances of a successful re-socialization. It is foreseen that the number of patients will increase significantly in the upcoming years.
More effective treatment programs and instruments for risk assessment are needed. For this, the causal relationship between psychopathology and delinquency must be better understood. This requires more criminological research.

Building on prior quantitative analyses by Rovers (1999) and Rovers and Boers (2009), the present article provides a quantitative overview of 60 years Dutch Journal of Criminology, with an emphasis on the period 1999-2018. Dutch criminology is beginning to lose sight of its first generation of researchers. Males still dominate the top 25 most published authors. A social network analysis of the co-author network on the one hand reveals a significant proportion of singletons. Many of the remaining authors on the other hand, are included in one giant component that links authors directly or indirectly by co-authorship.

In the present study, the role of genetic and cultural transmission in intergenerational continuity of rule-breaking behavior (RBB) was investigated. Based on the resemblance within 3,982 Dutch twin pairs, aged 13 to 17 years, the relative importance of genetic (G), shared environmental (C), and unique environmental (E) influences on RBB was estimated. Cultural transmission, the process of passing on knowledge, norms and values, can lead to similarities within families, and forms part of the shared environment of children growing up in the same family. The authors found no evidence for shared environmental influences, and consequently no indication of a role for cultural transmission. Genetic influences explained 60 percent of the variance in rule-breaking behavior at age 13 to 17, implying that intergenerational continuity at this age is mainly driven by genetic transmission.

In criminology, explanations for engagement in externalizing or criminal behavior are often found within the direct (social) environment of the individual. More specifically, family functioning, the quality of family relations and parenting strategies during childhood and adolescence are found to be related to the development of externalizing problems or criminal behavior over the life-course. Although less well studied, the opposite might also be true: externalizing problems or delinquency during childhood and adolescence may in turn also affect some important (family-related) transitions over the life-course, such as engagement in romantic relationships, the transition to parenthood, parenting strategies and broader family functioning. Not surprisingly, in life-course criminology there is increasing attention for familial similarities in externalizing and delinquent behavior. What underlies intergenerational continuity of criminal behavior? Under which circumstances behavior is continued over the course of generations? What is the role of the family? What is needed to break intergenerational cycles and facilitate earlier and more effective interventions? In this article, a literature review is provided on the role of the family in intergenerational continuity of externalizing or criminal behavior over the life-course and across generations.

This study (N=921) examines whether living together with a criminal parent moderates the intergenerational continuity of crime. Results are mixed, but show that the intergenerational continuity of crime decreases when the child lived together with the criminal parent for a shorter period of time. This association is most strong for children whose criminal mothers live on a large distance from them. Longitudinal fixed effects models, however, show that these results are likely the consequence of between-individual differences and therefore do not reflect causal influences on the intergenerational continuity of crime.

Previous research on intergenerational continuity of crime is primarily focused on transmission from fathers to children. In this article, we aim to give insight in the role of mothers in (the prevention of) continuity of organized crime. The results of our explorative study on 25 organized crime offenders based in Amsterdam and their partners and children, show that parenting skills and norms and values of mother seem to have an important role in both the intergenerational continuity of organized crime and the prevention of the transmission.

A well-established body of epidemiological research suggests that the prevalence of mental health problems (mental disorders, psychological distress, and substance use) in prisoner populations far exceeds that of non-incarcerated people in the surrounding community. Poor mental health in prisoners is associated with multiple adverse outcomes, including suicidal behaviour. In the past decade, novel data in Belgium and the Netherlands have been published on this topic, which have not been synthesized to date. The aim of the current systematic literature review was to provide an up-to-date overview of the mental health of prisoners in Belgium and the Netherlands. Based on 24 empirical studies conducted in 1997-2018, the authors conclude that people with mental health problems are overrepresented in Belgian and Dutch prisons, providing both a challenge and a public health opportunity to address the mental health care needs of a vulnerable and hard-to-engage population. Investing in the prevention and treatment of mental health problems not only benefits the prisoners concerned, but equally, society at large.

Illegal weed cultivation is increasingly perceived as an important societal problem. Most of existing research in this area focuses on the criminal organisations active on the cannabis market and the criminal profits that are gained here. The current study however focuses on the actors at the bottom of the cannabis market – the home growers – and aims at answering the following research question: what factors influence the chance of encountering an illegal weed cultivation at a certain residential address? In this study, the risk and protecting factors are taken into consideration on both the individual level (e.g. family composition and financial position of residents) and the neighbourhood level (e.g. social cohesion, physical disorganisation, level of criminality in a certain neighbourhood). In the current study, data of 401 illegal hemp cultivation sites discovered between 2011 and 2016 in homes in Eindhoven, the Netherlands, were analysed. Data from various quantitative data sources – like municipal data (BRP and data from the Social Domain) and data from the municipal neighbourhood monitors – were combined and analysed through a multilevel logistic regression. The results suggest that the likelihood of an illegal weed cultivation site is most prominently influenced by individual factors. Being married for instance seems to decrease the risk, whereas being divorced seems to increase the risk. The housing type also turns out to be of influence. On a neighbourhood level, physical disorganisation and the presence of other hemp cultivation sites in the neighbourhood are the only predictors for hemp cultivation. The results are discussed in the light of criminological theories regarding participation in crime, using the theoretical concepts motivation, opportunity, and control.

The present article examines the financial life of 131 jihadi travellers (JTs), also known as foreign terrorist fighters, from the Netherlands. For the purpose of the research, access was acquired to all their banking transactions in the year preceding their departure: over 60,000 transactions in total. Their income from work or employment, various forms of social assistance, student grants, and other income or expenditure were examined. The data provided a good picture of their financial independence, i.e., the extent to which they were capable of making their own living or needed to claim assistance from the authorities. The analysis shows that it is highly exceptional for Dutch JTs to be financially independent. Only 5 percent have sufficient income from work or employment without making any claims on the government for financial assistance, and are free of mounting debts. The low score can for a large part be explained by the fact that almost half of the JTs are under 23 years of age and/or receive a student grant. Their financial picture largely resembles ordinary students. Older JTs (over 22 years of age, and not having received a student grant for at least one year) underperform, however. Only 9 percent are financially independent. Financial support could perhaps be used to monitor or steer recipients’ role in society.
