Kijkervaringen van moslimjongeren en politiestudenten met ISIS-video’s en Hollywoodfictie in Nederland

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2019
Trefwoorden Dutch youth, ISIS videos, Hollywood, Visual skills

SamenvattingAuteursinformatie

    Between 2013-2017 there were many ISIS videos circulating. It was generally assumed that these videos would encourage young Muslims to radicalize and join ISIS. But what do we actually know about the imaginary world of young people? Do sociological aspects such as the economic, cultural and religious background play a decisive role in this? Can we use the films and TV series that young people see as an entry into their imaginary world? To what extent can image analysis provide knowledge that contributes to safety issues? Commissioned by the Department of Counterterrorism, Radicalization and Extremism (CTER) of the Dutch National Police, the IVMV Foundation invited, in a comparative pilot study, twenty Dutch youngsters (10 with a Muslim background and 10 police students) to share their viewing experiences with five trailers (3 Hollywood, 1 Netflix, 1 not explicit violent ISIS video) that touched on the ISIS issue. This resulted in a research report and a film (in Dutch as well as in English) that was presented in November 2017 (De Mare et al. 2017a; De Mare 2017b). A remarkable result was that their viewing experiences and feelings showed a lot of similarity.

Access_open De historie van de operationeel leider

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2018
Trefwoorden Historie, Operationeel leider, Bureaupolitiek, Beethovenfout voor samenwerking
Auteurs Bernard Groot en Ira Helsloot
SamenvattingAuteursinformatie

    The operational leader, the ‘gold commander’, fulfils a crucial function in crisis- and disaster management in the Netherlands. He is held responsible for the total coordination of all collaborating emergency services and supports/advises the Mayor, the Commander in Chief. Unfortunately, this function has never been very effective in practise, as shown by many evaluations. From a scientific point of view, it is easy to understand why the operational leader cannot be effective in the Dutch crisis management organisation. The operational leader has no authorities and has been seated in an emergency operation centre far from the Mayor. This article examines why this issue has not been solved, despite 30 years of studying and adjusting the Dutch crisis management organisation.

De geschatte waarde van het preventieprogramma Brandveilig Leven op basis van de contingente waarderingsmethode (CV – Contingent Valuation)

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 3 2018
Trefwoorden willingness-to-pay, contingent valuation, impact assessment, community fire safety
Auteurs David Bornebroek, Ron de Wit, Marc van Buiten e.a.
SamenvattingAuteursinformatie

    The Dutch Regional Fire Services collectively aim at preventing fire, casualties and damage. The main activity is informing citizens about fire risks and the appropriate measures they can take. From both a political and social perspective, it is valuable to know what the return of the Community Fire Safety program is. One way to chart the return of the program is a comparison of the cost of, and society’s willingness-to-pay for, the program. To estimate this willingness-to-pay, this article applies the contingent valuation method to a national representative sample of 806 Dutch citizens. The results show that willingness-to-pay of an average Dutch household is estimated to be between € 25.00 and € 35.67 per year provided the Community Fire Safety program improves the fire safety by 10%. At the national level, this amounts to 200 – 270 million euro annually. This value is seven to ten times more than the approximate costs of the current Community Fire Safety program.

Persoonlijkheidskenmerken van e-fraudeslachtoffers

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1-2 2018
Trefwoorden Online fraud, Big Five personality traits, Phishing, online marketplace fraud, cybercrime prevention
Auteurs Jildau Borwell, Jurjen Jansen en Wouter Stol
SamenvattingAuteursinformatie

    With the digitization of society, perpetrators gained new tools to commit crimes. Online fraud, also referred to as e-fraud, is one of the most common types of cybercrime. The present study focusses on two types of e-fraud: phishing and online consumer fraud. Although e-fraud always contains a digital component, the human is the weakest link in such crimes. Perpetrators deceive their victims to acquire sensitive data or to conclude a fraudulent sale, which makes victims unwillingly participate in the offence. However, not every person adheres to such fraudulent schemes. This raises the question what makes some people comply with these schemes and thus become a victim of cybercrime, while others do not. In this study, the differences between personality traits of e-fraud victims and the Dutch population were investigated. Personality traits influence the way people process information and react to situations, which also applies when people are confronted with e-fraud. Data were collected through an online survey, in which 224 e-fraud victims participated. The outcomes of the survey were compared with norm groups representative for the Dutch population. E-fraud victims, compared to the Dutch population, scored higher on extraversion, altruism and conscientiousness, and lower on neuroticism. Based on the findings, recommendations have been made for the development of targeted preventive measures against e-fraud.

Auteurs Frank van Gemert
SamenvattingAuteursinformatie

    The most important mechanism for crime prevention is just the presence of guardians. Some counter arguments against this thesis are discussed and rejected. By manipulating the presence of guardians it is possible to influence the level of prevention. It is argued that a large scale evaluation of such measures is wanted.

Veilig uitgaan: tegenstrijdige gevoelens over inzet politie en andere maatregelen

    Urban nightlife areas are widely renowned for their emotionally charged nature, affording greater opportunities for transgressions of social norms compared to daytime contexts. Yet, the ways nightlife consumers experience safety in the public spaces of nightlife areas has received limited attention in the academic literatures. This article approaches experienced safety in the public spaces of nightlife areas as emerging from encounters between human and non-human (material, social, cultural) elements grounded in time and space. Such elements include the characteristics of the built environment, the design of public space, police presence, lighting and also first and secondhand experiences and popular media discourses more generally. We hypothesized that encounters between such elements necessarily renders some ambiguity in experienced safety, in the sense that the effect of a particular element on experienced safety is always coproduced in the unfolding encounter. By drawing on a series of interviews with Dutch students in Utrecht, various types of ambiguity are shown to exist depending on both the particularities of the situation at hand and based on differences between individual circumstance and life course. Ambiguity is also shown to exist in the sense that mentioned elements may both comfort and alarm participants at the same time. Our findings infer that we should implement ‘safer nightlife’ initiatives that are tailored to particular contexts, situations and publics. The results also suggest that current interventions seeking to stimulate safety in urban nightlife settings might not be as successful in reducing/enhancing (un)safety as (popular) policy and media discourses have suggested.

Geweld tegen politieambtenaren

Beweegredenen en rationalisering door verdachten

Auteurs Danaé Stad en Jaap Timmer
SamenvattingAuteursinformatie

    This paper tries to answer the question why defendants use violence against police officers and whether, and if so how, they construct justifications for their own behavior. The study consists of an analysis of the situational aspects of violence against police officers and the characteristics of suspects. In addition, some suspects were interviewed about the incident in which they were involved. They were asked what their perception of the situation was, and what the background of the violence was. They were also asked for their opinion on the image of the police in general, and for their knowledge and perception of the relevant laws and regulations. The conclusion is that the motives for violence against a police officer lie in their belief that all men, police officer or not, are equal and should be treated with respect. Suspects feel treated unfairly and disrespectfully by police officers. Suspects feel that in such cases they are entitled to use force. Suspects are not aware of the differences between their own rights and responsibilities in such a situation and the authority that police officers legally have to use of force in order to perform their legal tasks.

Krachten op Straat: waar politiemensen uit putten en mee worstelen in hun alledaagse werk

Trefwoorden Police culture, Meaning, focus groups, values
Auteurs Merlijn van Hulst, Gabriel van den Brink, Wiljan Hendrikx e.a.
SamenvattingAuteursinformatie

    This article scrutinizes the forces that are at play during the work of police officers in the Netherlands in order to unravel how they shape and give meaning to police officers’ workaday practice. By doing so, we contribute to scholarly debates in the fields of criminology and public administration and give a new impulse to the Dutch debate on policy culture. Using insights from the literatures on police culture, policing, police morality and police styles as theoretical background, an empirical study was conducted using fifteen focus groups with a total of 83 police officers working at street-level as main method of data collection. After analyzing the transcripts through an iterative coding process, four main forces that influence police officers’ workaday practice emerged from the data, partly confirming and partly expanding existing research: 1) environment and public; 2) group culture; 3) organization and its supervisors; and 4) personal factors. However, by acquiring a deeper understanding of these forces in relation to each other and to their workaday practice, police officers’ ‘moral resilience’ will increase: it will help them to act well-considered, strengthening their ability to explain the logic of their actions.

Normbeelden als alternatief voor politiecultuur: de integere, neutrale en loyale supercop

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 0203 2016
Trefwoorden police culture, norm image, integrity, neutrality, loyalty
Auteurs Sinan Çankaya
SamenvattingAuteursinformatie

    This article argues that the notion of norm images does more justice to the complexity of the police organization. The notion of ‘police culture’ is heavily criticized for its homogenizing tendencies, monolithic connotations and stereotypical and negative evaluation of police work. Norm images have an analytical value, because (1) the images are contextualized within and connected to the rule of law, (2) the images are sufficiently analytically flexible for a situational and relational interpretation of the cultural processes within the police organization, and (3) the notion theoretically presupposes the resistance strategies of social actors against the norm images. The article illustrates the theoretical value of norm images by focusing on the dominant images of the ‘trustworthy’, ‘neutral’ and ‘loyal’ police officer.

    This paper focusses on the cultural aspects of rural policing by analyzing the stories of rural police officers. It shows that some central elements can be found in these stories. The core element of these stories is the constructed contrast with the imagined urban police: the rural police are said to be better integrated in the local communities, have more personal and direct relations with citizens, and have other strategies to solve problems. Rural officers often feel that they are seen and treated as inferior police. In contrast to this image they emphasize that they are more competent and have better methods of policing than the urban police, by avoiding the use of violence and escalation. These stories are an important way to construct an identity as rural police. They become more manifest at the moments that the specific identity of the rural police is under threaten.

De film Project X en de rellen in Haren (2012)

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1 2016
Trefwoorden Film, public imagination, public safety, Riots, Youth
Auteurs Heidi de Mare
SamenvattingAuteursinformatie

    On September 21th 2012, a sweet sixteen party in Haren (a Dutch village), announced on Facebook as PROJECT X Haren, turned into a riot in which youngsters clashed with the police. The blame was put on the film Project X (2012) that would have inspired adolescents to become aggressive and violent. However, like other adolescent comedies, this movie offers an insight in the adolescent state of mind, the role of humor and their lack of risk assessments. Much violence is (harmless) slapstick-like, boundaries are exceeded (sex, alcohol, drugs) and transgression is often directed against parents, teachers and the police. What is tested in the adolescent imagination is the public order. Film functions as a symbolic rite of passage, with carnivalesque inversions. Reacting in Haren on this adolescent state of mind with an administrative prohibition (‘there is no party’) confirmed the juvenile joke. Acting as if it is not a party but a huge disaster (by enlarging police forces) contributed to make the riot a reality that the youngsters themselves never imagined. The commission of inquiry recommends taking serious film and other forms of public imagination, because they contribute to our understanding of reality, especially concerning the perceptions of societal actors.

Een eenvoudige diefstal of toch een mishandeling?

Verschillen in type delict tussen zelfrapportage door slachtoffers en registratiesystemen bij instanties

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1 2016
Trefwoorden Slachtoffers, Registratie misdrijf, slachtofferrapportage, Delictcategorie
Auteurs Maartje Timmermans, Joost van den Tillaart en Annemarie ten Boom
SamenvattingAuteursinformatie

    From a secondary analysis of data from a survey of victims of crime, commissioned by the WODC, it appears that more than occasionally the registration of the type of offence by the police, the Public Prosecution Service and Victim Support Netherlands does not match the victim’s own reporting of the offence. In this article, the differences between victims’ reports and registrations regarding the nature of the victimization are exposed and the background of the differences is explored. Some offences seem to have an increased chance of being classed by victims in offence categories which differ from those of the registrations.
    Based on the secondary analysis, the authors conclude that it is important for the interpretation of future research among victims to identify the registered offence and explicitly verify this with the respondent. It is also good to consider what registration data is useful in samples to be able to identify differences between the registrations and the victims’ reports later. A practical implication of the discrepancy in the nature of victimization is that bottlenecks may occur in the connection between the support needs of victims and the supply.

De ervaren mogelijkheden om te re-integreren vanuit detentie

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 0304 2015
Trefwoorden Prison life, staff-prisoner relationships, correctional officers, rehabilitation, survey
Auteurs Toon Molleman en Karin Lasthuizen
SamenvattingAuteursinformatie

    In this article we examine which factors are correlated to the rehabilitation of prisoners. Central is the prisoners’ willingness during their imprisonment to work on a successful return in society. Assumptions derived from the theory were statistically tested with data from the Dutch Detainee Survey 2014; a large-scale study, in which prisoners held in all Dutch penitentiary institutions (N = 29) were surveyed (n = 2120). The results are in line with the theory and show that detainees are more positive about their (potential for) rehabilitation when they are more satisfied with a) the way they are treated by correctional officers (staff orientation); b) active deployment of the so-called Detention and Re-integration Plan; c) their daily program and activities, and; d) the experienced autonomy and personal decision-making. These outcomes offer fruitful perspectives on how the prison system can promote a successful return of prisoners in our society.

Gedragsprofiling: het bepalen van kwade bedoelingen en het meten van effectiviteit

Trefwoorden gedragsprofiling, afwijkend gedrag, psychologie, effectiviteitsmetingen, beveiligingspersoneel
Auteurs Helma van den Berg, Remco Wijn en Dianne van Hemert
SamenvattingAuteursinformatie

    Is behavioural profiling a viable alternative to more traditional approaches to profiling, viewed from the perspectives of underlying theoretical assumptions and measures of effectiveness? In this article we describe behaviour profiling in relation to other types of profiling, we review relevant psychological mechanisms that underpin behaviour profiling, and discuss effectiveness of this type of profiling as well as methodological aspects of measuring effectiveness. Behaviour profiling is a method largely used to select potential offenders before the offence is committed by observing and giving meaning to behaviours preceding incidents. Deviant behaviours exhibited by suspects can be either part of a modus operandi related to the offence, the consequence of increased stress, or an atypical response to prodding actions by security officers. Relevant psychological mechanisms to explain ways behaviour profiling works include direct characteristics of deception as well as indirect indicators of deception, such as a criminal being more self-focused and more cognitively engaged. Effectiveness of behaviour profiling is increased by training, including learning more about modi operandi and related behaviours, awareness of biases in general, specific relevant biases, and techniques to correct for these biases.

Burgerparticipatie en ‘crafting’ in het lokale veiligheidsbeleid

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 1 2015
Trefwoorden neighbourhood professionals, crafting, citizen participation
Auteurs Marco van der Land en Bas van Stokkom
SamenvattingAuteursinformatie

    An increasingly large degree of ‘public craftsmanship’ is demanded from professionals working in neighborhoods where citizens actively participate in security issues. The central question in this article is what role these neighbourhood professionals – mostly civil servants, (community) police officers and welfare professionals – play in facilitating and supporting civic projects in the field of security, how they create their ‘own’ social order outside of the formal policy domain of the organizations involved, and how they keep the public interest in mind. On the basis of three types of neighbourhood based projects – Neighbourhood Watches, ‘The Neighbourhood Governs’, and Residential Budgets – questions about the improvising and ‘crafting’ work of professionals are explored in this article. Such work is much needed in order to successfully establish connections between the different parties involved, navigate between the interests of citizens and organizations, recruit civilians while simultaneously amending their aspirations and expectations, safeguard public interests and ensure the progress of projects. Some professionals back away from these additional tasks and responsibilities they are increasingly face with. In many neighbourhoods much more is required from professionals however than the traditional roles as they were once defined by police, welfare and municipal organizations. In particular, the ‘new’ crafting professionals need to be able to deal with unreasonable expectations of ‘angry citizens’ who tend to dominate citizen participation in local security issues, act impartially and be accountable to the larger public, show personality and street credibility, and, finally, be attentive to unequal outcomes with regard to the distribution of safety and security projects in neighborhoods and districts.

SamenvattingAuteursinformatie

    This article describes a qualitative inquiry into Dutch people going to Syria for participating in Jihad. The inquiry compares theoretical findings with empirical facts, based on a content analysis and a document analysis, completed with ten depth-interviews. The results show that a combination of scientific findings on radicalisation and foreign fighters explains the jihad movement to Syria partly. The results also show that some factors, which have not recently be examined scientificly, are crucial for the character and extent of the movement towards Jihad.

Automatische gedragsanalyse voor effectiever cameratoezicht in de openbare ruimte

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2014
Trefwoorden Behavior analysis, Threat detection, Action recognition, Tracking, Re-identification
Auteurs Dr. Henri Bouma, Drs. Jeroen van Rest, Dr. ir Gertjan Burghouts e.a.
SamenvattingAuteursinformatie

    To improve security in crowded environments, such as airports, shopping malls and railway stations, the number of surveillance cameras (CCTV) is rapidly increasing. However, the number of human operators remains limited and only a selection of the video streams can be observed. This makes it hard for an operator to be proactive. This paper gives an overview of novel developments that may lead to more efficient camera surveillance and a more proactive role for camera operators. It focuses on three main steps in this process of video content analysis: pedestrian tracking, action recognition and behavior analysis. Tracking and re-identification (i.e. recognizing a person in another camera) was initially only evaluated on off-line benchmark datasets, though recently it has gained in maturity with live demonstrations in realistic crowded environments and measured improved operator efficiency. For action recognition and automatic behavior recognition, we observe that the simple patterns, such as loitering detection, are emerging in many applications. Human action recognition obtains very high performance values in controlled environments and it is progressing towards more realistic environments. More advanced approaches, such as pickpocket recognition in a shopping mall and the detection of threats to trucks on a parking lot have been developed and the first systems have been presented in live demonstrations. Our main contribution is that we structure the recent advances and the emerging applications of video analysis for security applications, explain and interpret the results, and identify opportunities for the near future.

    On 1 January 2009, the Dutch Temporary Restraining Order Act (Wth) entered into force. This act allows mayors to impose a ten-day restraining order (which may be extended to 28 days) on (potential) perpetrators of domestic violence, which prohibits these perpetrators from entering their own house and contacting their partner and/or children. During the restraining order everyone involved (evicted persons, those who stay behind and children) is offered a range of support and intervention measures. The law requires that within five years after its entry into force the Dutch parliament is informed of the effectiveness. To this end, a study was conducted between September 2011 and August 2013. The aim of this impact assessment is to gain insight in the effectiveness of the restraining order and the support services that are connected to it. The study was designed as a quasi-experimental study with an intervention group (restraining orders) and a control group (similar situations in which no restraining order was imposed). The study shows that the restraining order is associated with less incidence of new domestic violence. After imposing a restraining order new domestic violence occurs less frequently, and in case it does occur, fewer incidents occur than in (comparable) situations where no restraining order was imposed. The main explanation for the correlation found between the restraining order and the lower incidence of new domestic violence seems to lie in the support that is offered after the imposition of a restraining order. Moreover, the support seems to be more effective in the more serious cases than in the lighter cases. The degree in which antecedents of the evicted person are present and whether or not the evicted person is criminally prosecuted are not related to a lower degree of repeated domestic violence.

Professionele weerbaarheid en de politie

Naar een persoonsgerichte aanpak

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2014
Auteurs Geeske ten Wolde, Barbara Zwirs en Nelleke Kruse
SamenvattingAuteursinformatie

    The aim of the article is to analyse the correlations between social cognitive factors and behaviour that increases resilience by police officers and to assess in which way intention mediates the possible correlations. The study was based on Ajzen's theory of planned behaviour. A cross-sectional survey study was conducted in which 1.799 police officers in the Netherlands completed a questionnaire. Data was also collected by organising qualitative expert meetings with police officers. The data has been analysed using linear regression. The results show that intention had the highest correlation with behaviour that increases resilience and mediates the correlations of the social cognitive factors partially. Perceived behavioural control and attitude also had a direct correlation with behaviour that increases resilience. Subjective norm had a weak correlation with behaviour. This is the first study which tested TPB for behaviour that increases resilience by police officers. Because the design of this study was cross-sectional, more research is needed to better understand the causal relations between social cognitive factors and intention with behaviour that increases resilience by police officers.
