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.

This article relates criminological research on youth delinquency to the social development of adolescents. Starting point is a goal-framing approach which assumes that young people aim for the achievement of two goals: status (‘getting ahead’) and belonging (‘getting along’). Peers form an important context for achieving these goals. Therefore, the role of delinquency in peer networks is examined: on the one hand, the extent to which delinquency contributes to peer status, and on the other hand, how delinquency contributes to the formation of network relationships and, vice versa, how network relationships influence adolescents’ delinquency. Finally, several directions for further research are discussed.

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.

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.

In this introductory chapter we provide an overview of criminological research into intergenerational transmission of criminal behaviour that currently is, and has been, conducted both internationally and in the Netherlands. The most important findings of these studies are also discussed. Next, possible explanations are discussed for intergenerational transmission of crime in general, and more particularly for families that are involved in more serious and organized crime. Moreover, possible ways in which intergenerational transmission of crime can be prevented are discussed. Finally, we give some directions for future research on this topic and will introduce the contributions to this special issue.

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.

In The Netherlands not much attention has been paid towards the relationship between domestic violence and organized crime. In this contribution the question is addressed why this is. One of the answers is that there is doubt about the moral status of the victim of organized crime: it assumed that the victim has benefited from the proceedings of organized crime. When domestic violence and involvement with organized crime by one of the family members come together, the case becomes more complex and difficult to deal with. For that reason professionals and researchers should pay more attention to the overlap of both phenomena.

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.

Terrorism could be regarded as an extreme type of (violent) criminal behaviour. Against this background, there is much to gain if criminological attention would be extended to terrorism. In this overview, the authors describe how and to what extent criminological theories may provide a significant contribution to underlying causes of terrorism. Previous criminological contributions to the field of terrorism have primarily taken a theory-extended approach, including routine activity theory, rational choice theory and strain theory. However, so far such studies lacked empirical data. Further, to this day, not much is known about the empirical applicability of other criminological theories, including desistance theories, which warrant particular attention. In order for criminology literature to contribute effectively to our understanding of terrorism and to pursue better counter-terrorism policies, empirical evidence should first be obtained. In this way, terrorism researchers, in close collaboration with criminologists, can deepen our theoretical and empirical understanding of this relatively underexplored field.
