    In recent years, big data technology has revolutionised many domains, including policing. There is a lack of research, however, exploring which applications are used by the police, and the potential benefits of big data analytics for policing. Instead, literature about big data and policing predominantly focuses on predictive policing and its associated risks. The present paper provides new insights into the police’s current use of big data and algorithmic applications. We provide an up-to-date overview of the various applications of big data by the National Police in the Netherlands. We distinguish three areas: uniformed police work, criminal investigation, and intelligence. We then discuss two positive effects of big data and algorithmic applications for the police organization: accelerated learning and the formation of a single police organization.

Een planevaluatie van het Nederlandse systeem van Promoveren en Degraderen

SamenvattingAuteursinformatie

    Although reward systems are utilized in prisons worldwide, evaluations regarding their intended use are lacking. This contribution reconstructs the policy theory of such a system: Promotion and Demotion, as implemented in Dutch prisons in 2014. With a policy scientific approach the intended target group, means, goals and causal mechanisms of the system were delineated. The policy theory assumes three means, ten goals and 24 causal mechanisms. The policy theory is insufficiently empirically substantiated on a number of points and takes limited account of (cognitively) impaired prisoners. This accurate reconstruction offers a unique insight into the assumed functioning of a part of Dutch detention policy and provides starting points for international considerations of behavioral change in detention.

Vervalsingen van archeologische objecten

Tijdschrift Tijdschrift over Cultuur & Criminaliteit, Aflevering 2 2021
Trefwoorden archaeological forgery, James Ossuary, Shroud of Turin, Piltdown Man Skull, Archaeoraptor Fossil
Auteurs Noah Charney
SamenvattingAuteursinformatie

    This paper looks at a selection of famous forgeries of archaeological objects – the James Ossuary, the Shroud of Turin, the Piltdown Man Skull and the Archaeoraptor Fossil – to consider how these artefacts were falsified for personal benefit, whether in terms of fame or finance. The Shroud of Turin was identified as a forgery as early as 1389, and yet the value in terms of income from pilgrims was such that it continued to be displayed and venerated. The James Ossuary was forged for profit and notoriety, to gain renown and then to sell. The Piltdown Man Skull was one of many alleged forgeries by a man who sought renown by finding the ‘missing link’ that proved the Darwinian theory of evolution from ape to homo erectus. The same motivation drove the scientists who tried to pass off the Archaeoraptor Fossil as the ‘missing link’ that proved the relation of dinosaurs and birds.

Open heimelijke netwerken in de Nederlandstalige georganiseerde synthetische-drugscriminaliteit

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden synthetic drugs, poly-drug trafficking, organized crime, encrypted communication data, social network analysis
Auteurs Irma Vermeulen, Melvin Soudijn en Wouter van der Leest
SamenvattingAuteursinformatie

    In recent years, the authorities have dismantled several encrypted phone providers. These providers stored millions of messages about covert activities that were overtly exchanged between criminals. This type of communication offers a unique insight into serious organized crime and the people involved. Based on one such intercepted encrypted phone network, called PGP-Safe, we carried out a social network analysis on the Dutch-speaking synthetic drug market. Three findings stand out. Firstly, three-quarters of all accounts (N=4,158) are interconnected in a giant component, resulting in a criminal small-world effect. Secondly, the network appears to be robust. As a consequence, the removal of central accounts will hardly have any impact on the network as a whole. Thirdly, the majority of the accounts within the synthetic drug market is involved in poly-drug trafficking. The Dutch synthetic drug market is much more closely intertwined with other drug markets than is commonly known.

Het grensgebied als waterbed voor drugscriminaliteit?

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden displacement, cross-border crime, organized drug crime, policy effectiveness, balloon effect
Auteurs Rik Ceulen, Stephan Van Nimwegen en Toine Spapens
SamenvattingAuteursinformatie

    This paper concerns the question whether in the period 2011-2017 displacement effects occurred from the Netherlands to Belgium in the context of synthetic drugs production, cannabis cultivation, and retail of illicit drugs, and if so, how these may be explained. We conclude that displacement took place in modi operandi of retail drug dealers. This is explained foremost by the policy of banning non-residents from Dutch coffeeshops in border region municipalities. Dealers and traffickers responded by switching to local distribution in Belgium as well as deliveries by drug couriers. The synthetic drugs and cannabis cultivation markets show minor changes in modi operandi, but no changes occurred in choosing production locations. Displacement effects in the context of organized drug crime must be explained from a range of factors. Reality is therefore more complex than assuming that government interventions are the main cause of a balloon effect.

Een exploratieve studie naar de ambiguïteit van betrouwbaarheid van cocaïnedealers op Telegram Messenger

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden drug dealing, trust, signaling theory, social media, netnography
Auteurs Robby Roks en Joëlle Hendriksen
SamenvattingAuteursinformatie

    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.

De doorvoer van cocaïne via Nederland

Tijdschrift Tijdschrift voor Criminologie, Aflevering 2 2021
Trefwoorden cocaine trafficking, ping-pong trade, poly-drug trafficking, qualitative social network analysis, transnational networks of networks
Auteurs Vanessa Dirksen, Wouter van der Leest en Irma Vermeulen
SamenvattingAuteursinformatie

    This article describes traits of the hitherto underexposed transit trade of cocaine via the Netherlands, based on a qualitative social network analysis of a diversity of data. Research findings show that the transit trade via the Netherlands is dominated by poly-drug trafficking. It is noteworthy that streams of predominantly mono-drugs are entering the Netherlands, while mainly streams of poly-drugs are leaving the country. Our research furthermore shows that cocaine intended for European markets may be transited via the Netherlands to European countries to which the cocaine was initially imported. This is what we refer to as ping-pong trade. Another characteristic of the transit trade of cocaine via the Netherlands is that the actors involved, mainly coordinate parts of the cocaine supply chain. Although different groups within the cocaine distribution chain collaborate, this does not necessarily mean they actually know each other. Taken together, the organization of the distributive trade of cocaine is in this article positioned as an interdependent transnational network of networks (NoN). We suggest that future research into the transit trade of cocaine should apply such a transnational NoN perspective to fully grasp the interdependence of the micro and meso levels of the trade and, in so doing, ultimately comprehend the effect this may have on the macro level.

Uitdagingen voor een groene criminologie

Tijdschrift Tijdschrift over Cultuur & Criminaliteit, Aflevering 1 2021
Trefwoorden green criminology, environmental harm, non-anthropocentric perspectives, transspecies research
Auteurs Stephen Snelders en Nick Verouden
SamenvattingAuteursinformatie

    This essay discusses green criminology in relation to the development of non-anthropocentric research perspectives in history and cultural anthropology. Green criminological concepts of ‘environmental harm’ and ‘ecocide’ turn doing harm to nature and ecosystems, even when legal, into object of criminological research. Historical research exploring a wider time frame deepens and enriches criminological understanding of, e.g., wildlife trafficking and climate change. According active agency to animals and other non-human actors and attempts to create a new language transcending human-nature dichotomies, as undertaken in transspecies or multispecies history, anthropology, and narratology, offer substantial contributions to green criminologies of everyday life.

Het nieuwe activisme? Een kwalitatieve studie naar strategieën en betekenisgeving binnen de Nederlandse tak van Anonymous for the Voiceless

Tijdschrift Tijdschrift over Cultuur & Criminaliteit, Aflevering 1 2021
Trefwoorden green-cultural criminology, animal activism, impression management, new activism
Auteurs Anantha Thelen en Fiore Geelhoed
SamenvattingAuteursinformatie

    This article focuses on the ways in which animal activists that are affiliated with the Dutch branch of Anonymous for the Voiceless – a rapidly growing animal rights organization – shape their movement and actions in the context of the Anthropocene. Drawing on qualitative data, the results show that there are tensions between the way in which the organization presents itself to its audiences and the internal dynamics within the movement. In their frontstage performance, they highlight the open and non-coercive nature of their movement, which they describe as new activism. However, this performance contrasts with the abolitionist vision and internal dynamics within the movement, which is characterized by a clear hierarchy, strict rules for a vegan lifestyle and far-reaching consequences when not complying with those rules.

Daderschap in het antropoceen

Tijdschrift Tijdschrift over Cultuur & Criminaliteit, Aflevering 1 2021
Trefwoorden environmental crime, offenders, responsibilities, Anthropocene
Auteurs Lieselot Bisschop
SamenvattingAuteursinformatie

    Past and present human activity lies at the basis of the unprecedented environmental crisis we face today. This article explores the drivers and dynamics that are directly and indirectly responsible for the environmental crisis in the Anthropocene by using a green and organizational criminology perspective and combining it with insights from perpetrator studies. Responsible actors and responsibilities are discussed on societal, organizational and individual level. Lessons are drawn on how existing insights in criminology can be challenged to better accommodate for the ecological challenges in the antropocene and on what that means for criminologists experiencing and researching the Anthropocene.

Auteurs Janine Janssen en Marc Schuilenburg
SamenvattingAuteursinformatie

    ‘Antropocene’ is a wellknown concept among those that are concerned about the Earth’s future. Nevertheless, there is a heated scientific debat about the start of this era in history and the name ‘antropocene’in itself. In this contribution it is stated that that debate is helpful in raising important questions about the desatrous influence of mankind on live on this planet. Criminologists should take a stance and address these questions as well. This contribution includes a manifest that contains points for further action for criminologists.

Herstelrecht en recidivevermindering

Meningen van Surinaamse ex-gedetineerde jongemannen

Tijdschrift Tijdschrift voor Herstelrecht, Aflevering 1 2021
Trefwoorden Suriname, herstelrecht, jongvolwassenen, ex-gedetineerden
Auteurs Sabine de Vries
SamenvattingAuteursinformatie

    This article analyzes the opinion of twenty-four Surinamese ex-convicted young men on restorative justice. The results were obtained through four focus group sessions and a concise survey form. The factors (a) type of offense, (b) seriousness of offense and (c) prevention of recurrence were discussed. The opinions are divided, but the majority is of the opinion that restorative justice can mainly work for serious and violent crimes. Fear of revenge appears to be a barrier to participation. Employment has been indicated as the key to real recovery of the offender and prevention of recidivism (and thus satisfaction for the victim). The results provide insight into the susceptibility to restorative justice among this specific group in Suriname.

Burgers als institutioneel werkers. Een nieuw perspectief op burgerparticipatie in veiligheid

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 3 2021
Trefwoorden institutional work, citizen participation, fire, disruption, actor perspective
Auteurs Jasper Bongers en Wim de Jong
SamenvattingAuteursinformatie

    In this article we show how the concept of ‘institutional work’ can be used to study citizen participation in the field of security arrangements. Institutional work starts from the perspective of actors trying to influence security institutions, and not from the perspective of government (as concepts like the ‘participation society’ and ‘ladder’ do). As such, this dynamic concept can be a useful addition to the conceptual arsenal of security experts. By applying the concept to the case of the Voluntary Fire Brigade in nineteenth-century Utrecht (1879-1890) we show how institutional work can work in practice. Finally, we reflect on the contribution that institutional work can make to our understanding of citizen participation in the field of safety.

    Criminological research has emphasized the importance of procedural justice of authorities during encounters with citizens. Theory and prior research propose that the procedurally just treatment by the police influences, possibly via legitimacy, citizens’ willingness to cooperate with authorities in the criminal justice chain. This article tests the hypotheses of procedural justice theory using Dutch data of the European Social Survey (N=1,616). The results show an association between the procedurally just treatment of citizens by the police and cooperation with criminal justice authorities. However, this association has not been explained by the legitimacy of the police.

Een kijkje achter de schermen: een kwalitatieve studie over het ontstaan van cybercriminele carrières

Tijdschrift Tijdschrift voor Criminologie, Aflevering 1 2021
Trefwoorden cybercrime, cyber offenders, criminal careers, online disinhibition, pathways
Auteurs Sifra Matthijsse, Wytske van der Wagen, Elina van ’t Zand e.a.
SamenvattingAuteursinformatie

    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.

Auteurs Birte Vandaele, Thom Snaphaan en Wim Hardyns
SamenvattingAuteursinformatie

    The media are a main source of information on crime for citizens. Prior research shows that media and fear of crime are not independent of each other. Since fake news is spread through (social) media, the question arises what the relationship is between (perceived) fake news and fear of crime. To date, no large-scale representative research has been conducted on this topic. This study is based on a representative population survey (n = 1566) from 2019. This exploratory study shows a small but significant relation between the perceived prevalence of fake news and fear of crime.

Auteurs Martine School, Maurits de Graaf, Marie-Colette van Lieshout e.a.
SamenvattingAuteursinformatie

    In this paper, we present a mathematical model for the prediction of chimney fires using data collected by the Twente safety region over the years 2004 up to 2015. The explanatory variables used are the number of inhabitants per areal unit of 500 by 500 metres, the daily mean temperature and an indicator variable for October. Spatially and temporally correlated noise is added to be able to capture latent factors such as human behaviour. The model is validated using the data over the years 2016 and 2017. The model is implemented as a dashboard on a public website and yields as output a hazard map for chimney fires in Twente based on the weather forecast for the coming six days. This way, the dashboard can be used for prevention and planning purposes.

Een integrale veiligheidsmonitor als hulpmiddel bij het sturen op beleidsdoelen: theorie, praktijk en geleerde lessen

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2021
Trefwoorden monitoring, safety goals, cooperation, lessons learned, governance
Auteurs Ike Kroesbergen en Arthur Rijkers
SamenvattingAuteursinformatie

    This article provides a case description of the development of an integrated safety monitor for the governance on policy goals. The governance on these safety goals took place in cooperation between eight municipalities and Police, Justice, Fireworks, Health Care providers for addiction or domestic violence and partners in incident and crisis management. Two problems were adressed. The first problem is that the evidence on process and results of monitoring from data to interpretation and policy choices in cooperation with different safety partners, is scarce. The second problem is that monitoring of a wide range of indicators on integrated safety is also scarce. In our case, the gathering of data and the interpretation of these data together with all the partners formed a cyclical process. This corresponds with the theory of governance developed by Ansell and Gash in a meta-analysis in 2008. The starting conditions were made clear. The design of the monitoring process was translated into themes of working sessions with a group of policy advisors, giving them a structure for the governance on the policy goals. This group developed a layered set of indicators. These set of indicators was broken down in the four policy goals as well as in different steps in the safety chain. Indicators from different registrations of the safety partners were combined with indicators about the perception of safety measured by a representative sample of the residents. The layered set of indicators was supportive in the discussion about a well balanced monitoring on prevention, signals, interventions and effect. The data were interpreted together with the safety partners. This was helpful in creating a joint perspective on safety problems and in the discussion about meaningful policy actions. The challenge now is to persevere in the cyclical process from data to interpretation and shared understanding about policy goals.

Ontwikkelingstrajecten van hackers: een longitudinale studie naar defacements op Nederlandse websites

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2021
Trefwoorden Web defacements, hackers, cybercrime, trajectory analysis, Zone-H
Auteurs Steve van de Weijer, Rutger Leukfeldt en Thomas Holt
SamenvattingAuteursinformatie

    In this study we examined the developmental trajectories of hackers, based on their self-reported web defacements. During a web defacement, the content of a website is altered without permission. In total, 50,330 defacements of websites with a Dutch extension (.nl websites) were analyzed, which were executed by 3,640 defacers between January 2010 and march 2017. Using trajectory analysis, six different groups of defacers could be distinguished: two chronic groups of attackers and four groups who only defaced websites during a limited time period. These groups also differed in their motivations and modus operandi. The high frequent chronic attackers consist of less than 2% of the hackers, but were responsible for more than half of all defacements. It would therefore be most efficient when future interventions focus on this small group of chronic offenders. For future studies it would be an interesting topic to examine the content of the web defacements.
