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.

Unlike criminal career research into the criminal behavior of natural persons, longitudinal research into rule violations by corporations is still scant. The few available studies are mostly limited to US corporations, and suffer from either a small sample size or a short follow-up period, limiting the generalizability of their findings. The present study uses longitudinal data on rule violating behavior of 494 Dutch chemical corporations derived from yearly inspections (N=4.367) of the relevant safety and environmental agencies between 2006 and 2017. The study aims to gain insight in the patterning of rule violations by Dutch chemical corporations, and the extent to which these patterns are associated with sector and corporate characteristics. The results show that rule violation is common among Dutch chemical corporations. A small minority of chronically violating corporations however, is responsible for a disproportional share of all observed rule violations. Using group-based trajectory modelling (GBTM) we distinguish several longitudinal patterns of rule violations in our data. Available sector and corporation characteristics are only weakly associated with the patterns of rule violations identified.

Women are less likely to commit criminal acts than men. This gender gap appears to be particularly pronounced in white-collar crime. This systematic literature review examines existing theories, such as the situational hypothesis and the ‘gendered theory of focal concerns’ and evaluates to what extent they find support in empiricism. The results seem to offer the most support to the ‘gendered theory of focal concerns’. This nourishes the hypothesis that with an increase of women at positions in the upper tiers of the company ladder a decrease in the prevalence of white-collar crime can be expected. However, it is also possible that the explanation of corporate crime does not lie in a lack of femininity, but in a lack of gender diversity. Furthermore, limited access to informal criminal networks, the ‘old boys networks’, seems to play an important role in the gender gap of white-collar crime.

Internationally, research on the experiences of white-collar offenders with the criminal justice system and the consequences of prosecution and conviction is scarce. Such research becomes more relevant, as the response to white-collar crime has become more punitive and more offenders are convicted. This paper presents the experiences of the co-author as a convicted white-collar offender as an autobiographical case-study. In this cases study, the consequences and experiences during four phases (investigation, prosecution, sentence-execution and post-sentencing) are analysed on four live-domains: health, private life, social life and professional life. Such an approach could be a blueprint for further and more systematic study of the experiences with and consequences of criminal justice for white-collar offenders. Such study can shed light on the effects and actual achievement of goals of punishment for white-collar crime.

This article studies the development in the prison system over the period 1837-2016 in the Netherlands. It describes trends in three characteristics of the Dutch prison system: (a) the number of prisoners, (b) the number of cells, and (c) the inflow of persons from the free society. The findings are twofold. On the one hand – when examining absolute numbers – the article shows that three distinct periods can be distinguished: a period of 140 years with low stable numbers (1837-1975), four decades in which the numbers tripled (1975-2005), and a subsequent decade where the numbers halved (2005-2016). On the other hand – when examining relative numbers, i.e. per 100.000 inhabitants, and thus controlling for the growth in population – the article displays that developments in the prison system in the Netherlands between 1837-2016 can best be characterized by a long-term continuous decrease in detention.

In the United States, the term disproportionate minority contact (DMC) is used to refer to the disproportionate number of minority youth who come into contact with the juvenile justice system. Statistics on DMC in the United States put the issue on the political agenda and measures have been taken to reduce the inequality. In the Netherlands, there are some studies on the representation of ethnic minority groups in suspect statistics, but data regarding all ethnic groups at various stages of the juvenile justice chain are lacking. Due to this lack of information, DMC is not mentioned in Dutch research literature and is not a political issue. Therefore, the purpose of this article was to explore whether DMC existed in the Netherlands and whether elements of the US policy could be applied to the Dutch situation. To investigate this, the likelihood (odds ratio (OR)) was calculated for young people with a migration background to be registered and held as a suspect, to participate in an alternative punishment program (Halt) and their likelihood of incarceration. It turned out that the OR for young people with a non-Western migration background to be registered as a suspect was more than three times as high, with an OR of 5 or higher for some ethnic groups. The chances of a Halt-settlement were much lower for young people with a non-Western background. The odds of ending up in a youth prison was over six times higher for youngsters with a non-Western background compared to their Dutch native peers. For young people of Caribbean and Moroccan origin the likelihood was more than ten times higher. These results showed that DMC is present at all examined stages in the Dutch juvenile justice chain. The large overrepresentation of young people with a migration background (especially of Moroccan and Caribbean origin) shows that further research is needed in order to develop programs to reduce DMC. To establish this, it is important to register the ethnic origin of the individuals at all stages of the juvenile justice chain.

Early literature on female perpetrators of World War II focused on labelling the accused as deranged psychopaths, thereby distinguishing the group of perpetrators from the vast subdued and ‘normal’ population. While this perception has changed over the past decades, the perception of female perpetrators has remained limited either way, women are denied having a lot of agency when perpetrating crimes in conflict. Similar to the ‘mad Nazi’-theory these narratives imply that female perpetrators are different from ‘ordinary’ women, as their actions collide with notions of ideal femininity. This empirical research has shown that in the case of female perpetrators of World War II in the Netherlands it seems that they can be seen as ordinary women operating in extraordinary circumstances. In this study, a special group of female war criminals is described. Against the background of early post-war imaging of such women and more recent research on female perpetration during wartime, an analysis of Dutch perpetrators who received severe punishments after the War, is made. Based on unique historical data, the criminal career of these women as World War II perpetrators is analysed. The outcomes show that a notable part already had a criminal record before the war and that the perception of who they were and why they acted the way they did needs reconsideration, since they were not psychologically weak and incompetent. They were generally young, unemployed and low educated and they planned and committed their crimes of treasons in order to create better living conditions for themselves. In fact, one can claim that these women are likely to be ordinary people influenced by dispositional and situational factors.

In the current criminological literature surprisingly little is known about the development of partnerships of detainees during and after detention. In particular, it is unknown to what extent existing differences in the relationship quality at the start of the detention period continue. Therefore, this study examined how the partnerships of detainees developed by using data from the Prison Project. This is a longitudinal study in which 747 detainees with a partner were interviewed at various moments during detention and six months after detention. The results show that bad partnerships at the beginning of detention remain in general bad or end during and/or after detention, while the average to good relationships remain the same.

This study explores the influence of police detention centres environments on police suspects’ psychological wellbeing and sleep problems. Results showed that suspects detained in a police cell experience a decreased psychological wellbeing, that they sleep poorly, and that their psychological wellbeing is related to sleep problems. Implications for police detention in relation to suspects’ psychological wellbeing and sleep problems, as well as directions for future research on police detention centre environments, are discussed.

This article examines whether samples obtained through offline and online modes, within the context of juvenile delinquency research, differ from one another, when in principle the same population of youths could be reached. Youths participating through a computer-assisted web interviewing mode (CAWI) report less delinquent behaviour, fewer risk factors for delinquency, and exhibit a lower prevalence in police registration, compared to youths participating through a mixed computer-assisted personal interviewing and computer-assisted self-interviewing mode (CAPI/CASI).

Nuclear energy is a controversial topic in Belgium and the government strives for a nuclear exit by 2025. However, there are few notable policy efforts which prepare the country for such a future. The framing of nuclear energy is crucial in the ongoing debate about its usage. In this article, the author analyses the discourse of the nuclear lobby and government through a green criminological lens. She compares the discourse with academic literature about nuclear energy and identifies ideological strategies via the analytical framework of Larrain (1983).

Illegal (IUU) fishing is a relatively understudied area within criminology. In this article the authors briefly describe what IUU fishing entails, what is known about the consequences of such fishing, and will list law enforcement issues. They illustrate how illegal fishing can be organized in different ways, and will give some examples of fish fraud. The authors also discuss the (massive) measurement issues. The ecological impact of IUU fishing constitutes an important reason for more research into this phenomenon.

That criminal networks are active in the illegal exploitation of timber is increasingly acknowledged. The degree of organization of these networks, and the way in which they use (threats of) violence and corruption, is less known. This article describes and analyses, on the basis of various, including local, sources, how organized criminal groups in the Amazon rainforest illegally harvest trees which they sell on the (international) market and how they try to stay immune from the law by using threats, violence, fraud and corruption. This article also discusses the first results of a three-year pilot (2014-2017) of community-based forest monitoring and protection with waterproof GPS-camera’s, developed with communities and with support of the Brazilian Public Prosecutor’s Office.

Developing effective anti-poaching strategies is difficult because of complex interactions between animals, poachers, and rangers. This study shows the utility of agent-based models (ABM) for unraveling these interactions, and their underlying mechanisms, to identify relevant components for planning ranger operations. Here, two patrol strategies were simulated using an ABM for wildlife crime to quantify their effectiveness under different circumstances. The model showed border patrols to be more effective than search patrols in protecting both solitary and herd animals. Furthermore, the model suggests that rangers catch fewer poachers when patrols are overly focused on locations where poaching was detected previously. The study illustrates that disciplined model development and testing is required for useful conclusions to be drawn, from a fully understood ABM.
