Gaan veiligheidsmaatregelen ten koste van de servicebeleving?

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2014
Trefwoorden customer experience, service perception, surveillance measures, legitimateness
Auteurs Rick van der Kleij, Maaike Roelofs en Dianne A. van Hemert
SamenvattingAuteursinformatie

    Surveillance measures in public places such as train stations, large events or business premises are aimed at increasing security at those specific locations. They enable people to move around securely at public (high) risk locations. However, people often experience these measures as an obstacle. Too much security often results in limitations of freedom of movement and violations of privacy. Could surveillance measures be designed in such a way that they are perceived more as a ‘service’? The authors studied the variables that influence whether people experience surveillance as a service or as a hindrance. At three surveillance locations (Schiphol Airport, Hoog Catharijne shopping area and Amersfoort railway station) more than thousand visitors were surveyed. They were asked how they experienced service and security on the site. The results show that there are differences in service perception in relation to security measures at the three locations studied. They show how the tension between service and safety can be reduced and provide clues for improving security measures. The results can be used by owners of public locations, surveillance stakeholders or private companies for the optimalisation and re-design of a location, as their goal is to attract loyal visitors, who are not frustrated and are willing to use the location frequently, and who preferably speak positively about the location to others. Also the security measures themselves can be improved, both technical security measures as well as human security measures.

Jihadgang naar Syrië: een wetenschappelijke benadering

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2014
Trefwoorden Jihad, Foreign fighters, Syria, radicalisation
Auteurs Nick Platje Msc
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.

Het gebruik van Twitter door de wijkagent en het vertrouwen in de politie

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 3 2014
Trefwoorden social media, Twitter, police, confidence, trust, community policing
Auteurs Dick Roodenburg en Hans Boutellier
SamenvattingAuteursinformatie

    Community policing is a common strategy in the Dutch police organization: working in a geographically bounded area, in close proximity and engagement with the local population. The use of Twitter by local police-officers is an increasingly popular way of communicating in this context. Prior research has indicated that there is a positive relation between the use of Twitter by the local police officer and citizens’ confidence in the police. But what factors determine this confidence and how can it be strengthened by using Twitter? This article examines the nature of police tweets and shows how tweets can contribute to improving the degree of confidence between citizens and the police. To determine what factors influence confidence we made use of the model of trust and confidence by Jackson and Bradford. This model differentiates between ‘effectiveness’, ‘fairness’, and ‘engagement’. These three factors are used to explore the way tweets might influence confidence in policing. The empirical research included interviews with three police officers who twitter actively, as well as interviews with 30 ‘followers’ living in the neighbourhood where the police officer works. Also an analyses has been carried out of the tweets made by the police officers in one year, 3.506 tweets in total, by categorizing the tweets according to the model of Jackson and Bradford. We conclude that the model of Jackson and Bradford is useful to explore the possible relationship between the use of Twitter and citizens confidence in the police. Using Twitter by the local police officers seems to make a possible contribution to the degree of confidence in the police. Our categorization of Twittermessages allowed us to give practical recommendations to local police officers how to use Twitter in order to improve confidence among citizens. The data also suggest that followers appreciate the fact that local police officers show their knowledge of current affairs in the neighbourhood.

De samenhang tussen fysieke en sociale veiligheid in theorie en praktijk

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 3 2014
Trefwoorden safety, security, disciplinary boundaries, multidisciplinary collaboration, networked coordination
Auteurs Hanneke Duijnhoven, Kim van Buul-Besseling en Nathalie Vink
SamenvattingAuteursinformatie

    This article discusses the complex relations between the organizational fields of safety (i.e. disaster and crisis response) and security (i.e. crime prevention and public order), and the ways in which disciplinary and organizational boundaries make it difficult to come to a better integration or coordination in the safety and security domain. Based on results of a research project on cooperation and information-sharing between organizations in the fields of safety and security, the authors argue that it is not realistic to refer to safety and security as relatively independent fields. Instead, it would be more useful to approach it as a connected domain, encompassing both safety and security disciplines. Yet, the separation of the two fields is strongly embedded in the culture and responsibilities of organizations in these fields, which reinforces the disciplinary boundaries in the domain. Nevertheless, in the last few years it seems that there is an increasing recognition of the need for multidisciplinary collaboration in the safety and security domain. This paper explores possible directions for creating more coherence and integration in the safety and security domain. The authors believe that much progress can be made if key stakeholders in the safety and security domain are able to adopt a broader, multidisciplinary perspective when approaching safety and security events.

Een terughoudende praktijk

Over de praktische vraagtekens bij het bestrijden van onveiligheidsgevoelens

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 3 2014
Trefwoorden reducing fear of crime, reflective practitioners
Auteurs Remco Spithoven
SamenvattingAuteursinformatie

    Despite the international scientific inconclusiveness about the nature of the fear of crime, the strategic layer of the Dutch government aims to reduce the fear of crime in general by 2017. But their policy-goals were not accompanied with a plan how to realize them. Meanwhile, local practitioners claim to be in search of practical tools and substantive support how to fight back the public’s fear of crime. This study was aimed to feed the discussion with a constructive and realistic input from both the practitioners and the scientific view. The research question was: ‘What do local practitioners do against the public’s fear of crime and how can these activities be improved?’ 36 local practitioners from Dutch local municipalities, the police force and the public prosecutor were interviewed. Schön’s idea of the ‘reflective practitioner’ (1983) was the underlying argument to make practical knowledge about reducing the fear of crime explicit. The respondents from both institutional layers of local ‘policy advise’ and ‘policy implementation’ were quite reluctant about fighting back the public’s fear of crime. They aim to reduce the fear of crime in a doubtful and indirect way. Because many sources of the public’s fear of crime were unknown to them or were not in the reach of their professional activities. In this way, the interviewed local practitioners approach strongly aligned with the advice of international scientists to be reluctant and realistic about fighting back the public’s fear of crime. We advised an approach of ‘local fear of and worry about crime’ in dialog between international science and the interviewed local Dutch practitioners. The results of it will probably not contribute to quantitative policy goals at the national level, but rather to custom fit, qualitative improvements on the local level. This will probably be the most effective way to fight back the few tractable elements that make up the fear of crime.

    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.

    The economic analysis of (potential) disasters is an important method to determine the efficacy and efficiency of investments in disaster prevention and mitigation. The Dutch National Risk Assessment (NRA) provides an integrated, whole-of-government and all-hazard approach to Dutch national security. The strategy does not only intend to identify capacity gaps and define measures regarding individual threats and risks, but also to enhance capability planning and policy development concerning overall national security. The approach is multi-disciplinary and based upon scenarios which are evaluated and graded in terms of impact and likelihood according to a unified scoring method. Economic impact is one of the criteria in the NRA risk assessment methodology. This article provides a review of the (applied) scientific literature of the many economic tools and methods that have been used worldwide to estimate the (potential) impact of disasters and provides concrete applications at the micro and macro levels to Dutch cases and scenarios that were developed during the five annual cycles of the NRA's existence (2007-2011). We discuss pros and cons of applied methodologies.
