In order to advance our understanding of digital drug markets on social media, this article examines the trustworthiness of cocaine dealers on Telegram Messenger. Based on an exploratory netnography, we illustrate that digital dealers on Telegram Messenger use a number of sales tactics to attract potential customers, emphasizing the quality of the goods and service and (competitive) pricing strategies. These sales tactics include various signals that seem intended to appear as trustworthy as possible to potential customers. Seen from the perspective of signaling theory, our study highlights the ambiguity of these signals that, depending on the online observer, could both signal trustworthiness and untrustworthiness.

This qualitative study examines how criminal careers in cybercrime start and can be explained. Based on offender and expert interviews, the authors conclude that traditional factors linked with the initiation, such as a maturity gap (for juvenile offenders) and opportunism (for adult offenders), in combination with different types of (online) disinhibition – social, technical, situational and psychological – can explain the start of a criminal career. Features of the digital context appear to play a major role in the development of a criminal career and this requires more online supervision and education about – among other things – legal alternatives and the risks and boundaries of the online environment.

In this study we examine whether parental monitoring remains a protective factor in the lives of emerging adults, as well as the extent to which monitoring in other settings replaces the protective role of the parents. We use data collected for the TransAM project, a longitudinal survey of 970 emerging adults (18-24 years) to examine monitoring in a range of different contexts using an instrument based on Stattin and Kerr’s parental monitoring scale (2000). Results indicate that whilst parental control plays a protective role in the first years of emerging adulthood, we find no evidence that monitoring in other settings replaces the protective role of parents. However, monitoring of the self, i.e., self-control, has an increasingly strong relationship with delinquency during emerging adulthood.

The aim of this study was to provide more insight in prevalence and aetiology of juvenile frequent offending, employing police registered data as well as self-report information. We combined data about 519 youths that participated in a self-report study in the region of The Hague with police register data (the HKS system) from the police unit of The Hague. The results indicate that a substantial part of youths that report a large amount of offenses themselves are not formally known as ‘juvenile frequent offender’. Causal factors derived from four major criminological theories can be found in a more pronounced way among juvenile frequent offenders than among youths that incidentally commit offenses. In general, there are similarities between the characteristics of juvenile frequent offenders defined by police register data and those defined by self-reports, but, on average, frequent offenders that are known by the police spend more time unstructured socializing with friends. We conclude that research using the method of self-report is well capable to find juvenile frequent offenders, and that this method also leads to useful information about the causes of their delinquent behaviour.

This article investigates whether cyber delinquent behaviour of school friends, other offline friends and online contacts is related to cyber delinquent behaviour of individuals, and whether this relation differs for cyber dependent, cyber enabled and traditional crime. We used both direct and indirect measures of cyber delinquency of friends. We employed data from the first wave of a large-scale study on the causes of online delinquency among Dutch juveniles (n=889; mean age=16.8 years). The results suggest that both direct and indirect measures of levels of friend delinquency were related to levels of individual cyber offending. However, indirect measures had a stronger association with individual online delinquency than direct measures. This suggests that respondents make incorrect estimates of their friends’ levels of online delinquency. Moreover, no differences were found in the strength of the relation between individual online offending and indirect measures of online offending of school friends, offline friends and online friends. This suggests that friends of different types all play an important role in individual online offending.

Young people’s delinquent behavior remains a social problem of concern to parents, local residents, teachers, police officers and administrators. With respect to effective interventions, the dominant focus is on ‘what works’. Relatively little is known about ‘who works’. In this study, based on a survey of 679 vmbo-pupils, it was investigated to what extent receiving ‘sternness with love’ from a professional may contribute to mitigating delinquency. For this research, unique graphically supported measuring instruments were developed that enable participants of the target group – including those who suffer from mild intellectual disabilities – to independently fill out the questionnaire. The results based on regression analyses suggest that there is no support for the supposed contribution of the interaction between sternness and love or of the three-way interaction between delinquent friends, sternness and love in explaining the variance of delinquent behavior. The results further show that having delinquent friends is related to participants’ delinquency. The results of these analyses also suggest that the relevant professional’s approach with ‘sternness’ or with ‘love’ moderates the relationship between delinquent friends and committing theft.

Studies investigating peer influence on risk behaviors, such as antisocial behavior and substance abuse, mostly study the amount of change in which adolescents adapt their risk behavior to become more similar to their friends. Onset of risk behavior, changing form having no experience to having any experience with risk behavior, has been studies far less. This study investigates friends’ influence on the onset of risk behavior and their influence in changes in risk behavior. Hypotheses were tested using SNARE (Social Network Analysis of Risk behavior in Early adolescence) data (N=1.144), containing information on risk behavior (i.e. antisocial behavior, alcohol use, and tobacco use) and friendship networks at three timepoints during the first year of secondary education (M_age= 12.7; SD=0.47). Analyses, using longitudinal social network analysis (RSIENA), showed that although adolescents adapt their risk behavior to become more similar to their friends, they are not influence in by their friends in the onset of risk behavior. These findings suggest s more nuanced role of friends in the onset of risk behavior. Interventions aiming at friends might benefit from differentiating between the onset and further (dis)continuation of risk behavior as these friendship influence processes might be less relevant for the onset of risk behavior.

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.

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.

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.

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.

Intimate partner homicide (IPH) constitutes one of the most prevalent types of homicide. This study aims to assess the nature and prevalence of intimate partner homicide in the Netherlands in the period 2009-2014. In doing so, we make use of police data, court data, and media articles. Findings show that IPH occurs 29 times per year, resulting in a victimization rate of 0.20 per 100,000, similar to other Western-European countries. Our results further show a decline in IPH in the last years. IPH in the Netherlands mostly occurs in heterosexual relationships, and involves male perpetrators and female victims. Finally, we reflect on possible causes for the decline of this type of homicide.
