De ene graffiti is de andere niet

    Graffiti has been linked in empirical studies to disorder, fear of crime, avoidance behavior, vandalism and delinquency. In most of those studies, graffiti is treated as an abstract and uniform concept: no distinctions are made between one graffiti or another. Policies based on this assumption hold a zero tolerance approach, meaning all graffiti is deemed undesirable and is or should be removed. This has been criticized by several (theoretical) studies. On the other hand however, ethnographic studies present graffiti as a multifaceted phenomenon, serving as a means of communication, resistance and protest or as an art form. The current study investigates the assumption that graffiti is perceived as a homogeneous and undesirable environmental feature. This article examines whether graffiti is actually perceived uniformly by Dutch citizens, and if not how people distinguish between different graffiti; which types of graffiti are perceived as disorder and whether different types of people exist based on their attitudes towards graffiti. An extensive questionnaire was designed, based on a thorough analysis of the literature and empirical pilot studies. A nationally representative sample responded to general questions with respect to graffiti and judged eighteen specific examples of graffiti on a reliable scale that measured perceived disorder. Results indicate that people vary enormously in their ideas and attitudes. Also, not every graffiti is the same, meaning graffiti is not a homogeneous, uniform phenomenon. Both type of graffiti and the location on which the graffiti is situated relate to the degree of perceived disorder. For example, tags, small scribbles, were considered a public nuisance more than pieces, large colorful images. Also, graffiti on a house or car is perceived much more as disorder than graffiti in a skatepark. The diversity in views necessitates a normative

Agenten volgen via Twitter bevordert positieve beeldvorming, stimuleert de meldingsbereidheid en verandert de veiligheidsbeleving

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2012
Trefwoorden Twitter, community policing, transparency, perception, willingness to report

SamenvattingAuteursinformatie

    Since November 2009, the regional police of Groningen facilitated their community officers with Twitter. According to the principles of community policing, they are enabled to shorten the distance between the police and citizens by giving them a direct connection. Such a connection should stimulate interaction, while at the same time it should make people feel more safe. In addition, Twitter also creates possibilities for the police to be transparent. Sharing of information should alter citizens’ perception towards the police.
    A comparison has been made, by using an online questionnaire, between followers and two kinds of non-followers. The effects of following twittering community officers have been demonstrated by using statistical analyses, taking into account relevant control variables. On the basis of these analyses it has been demonstrated that following a twittering community officer did not positively or negatively alter the perception of safety of their followers. However, an enhanced information position has made followers much more aware of local disorder and crime. Thanks to shared information about police actions to sustain and improve local safety and livability, followers’ perception of safety has not been altered negatively.
    Followers’ perception towards the police organization has been positively altered, thanks to the twittering community officers. Especially the sharing of information and involving citizens into local policing helps the police to alter the perception of citizens towards their organization. In addition, it has been shown that followers’ willingness to report has been improved. Thanks to the ease of use of Twitter and the shortened distance between the police and citizens, followers do frequently contact the police or a community officer to share some information, or to report some crime or disorder. However, it has been shown that Twitter should just be presented as complementary to existing ways to contact the police.

Identificatie van Nederlandse jongeren die risico lopen op internet

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2012
Trefwoorden Youth, internet use, online victimization, risk profile, risk factors

SamenvattingAuteursinformatie

    This article describes the findings of a national representative survey on online victimization. The survey was conducted in the Netherlands in 2011 amongst youth aged 10 to 18. Purpose of this research is to identify various risk factors related to cyber bullying, online sexual activities and online financial crime (e.g. e-fraude and commercial deceit). More than 9 percent of the youths had negative experiences with cyber bullying, about 5 percent with e-fraude and over 11 percent with commercial deceit. Also unwanted online sexual solicitations (6%) and unwanted exposure to sexually explicit internet material (12%) occurred with some regularity.
    This research complements earlier research on youth victimization in two important respects. First, we paid explicit attention to determine whether the youngster experienced the online incident as negative, neutral or positive. Our strategy to address negative experiences ensures the identification of actual victims. Secondly, we made it possible to identify and compare risk factors on various types of online crime. Girls are more likely to be cyber bullied, to receive unwanted sexual solicitations and to be unwantedly exposed to online pornography, whilst boys are more at risk to be commercially deceived or scammed.
    Internet use and behaviour are significant risk factors to comprehend online victimization. Above average use of instant messaging and clicking on (advertising) hyperlinks without restraint, are important predictors for online victimization. Finally, online disinhibition - a loosening of social restrictions during interactions with others on the Internet - and low self-control, turn out to be significant risk factors.
    It is difficult to accept certain risks, especially when youth are involved. However, children have to learn themselves to assess risks, to deal with them and to learn from them. It is important youths built up resilience to adequately react on negative online incidents and to reduce online vulnerability.

Slachtofferschap van online oplichting nader onderzocht

SamenvattingAuteursinformatie

    Consumer fraud seems to be widespread, yet little research is devoted to understanding why certain social groups are more vulnerable to this type of victimization than others. The present paper deals with internet consumer fraud victimization, and uses an explanatory model that combines insights from self control theory and routine activity theory. The results from large-scale victimization survey data among the Dutch general population (N=6,201) reveal that people with low self-control run substantially higher victimization risk, as well as people performing ‘risky’ routine activities, such as online shopping and participation in online forums. Though a minority share of the self-control-victimization link is indirect – because people with low self-control are more involved in risk-enhancing routine activities – a large direct effect on internet fraud victimization remains. This suggests that, within similar situations, people with poor impulse control respond differently to deceptive online commercial offers.
