De rol van sociale media bij rampen en (mini)crises

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2016
Trefwoorden Sociale media, Crises, Crisiscommunicatie, geruchten
Auteurs Menno van Duin, Vina Wijkhuijs en Jan Eberg
SamenvattingAuteursinformatie

    Professionals dealing with crises are more or less forced to a next level of crisis communication and crisis management. This is because of the influence of social media. Messages on Twitter, Facebook and other social media can have a significant impact on the course of developments during a crisis. Sometimes in a positive way, when help is mobilized quickly and people can be informed almost instantly. On other occasions the impact is more negative, when for instance rumors lead to false accusations or threats. In the past several years, crisis management authorities have built up more experience with the use and application of social media and monitoring tools. There are still cases where officials and professionals are taken by surprise because of the shift stream of messages and their impact on public opinion and crisis control. But also lessons have been learned, e.g. in terms of online and offline reactions, cooperation with the public, and rumor control.
    This article gives an overview of research results in literature and summarizes the outcomes of a case study research project.

Politieonderzoek in open bronnen op internet

Strafvorderlijke aspecten

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 2 2012
Trefwoorden criminal investigation, surveillance, OSINT, investigation powers, legal basis
Auteurs Bert-Jaap Koops
SamenvattingAuteursinformatie

    Analysing large amounts of data goes to the heart of the challenges confronting intelligence and law enforcement professionals today. Increasingly, this involves Internet data that are ‘open source’ or ‘publicly available’. Projects such as the European FP7 VIRTUOSO aim at developing platforms for open-source intelligence by law enforcement and public security, which open up opportunities for large-scale, automated data gathering and analysis. However, the mere fact that data are publicly available does not imply an absence of restrictions to researching them. This paper investigates one area of legal constraints, namely Dutch criminal-procedure law in relation to open-source data gathering by the police. Which legal basis is there for this activity? And under what conditions can foreign open sources be investigated?
    After sketching the context of the VIRTUOSO project and legal constraints of open-source intelligence in general, this paper discusses provisions of the Dutch Police Act 1993 and the Code of Criminal Procedure to determine which is the correct legal basis for gathering data from openly accessible and semi-open sources. Next, cross-border gathering of data is discussed on the basis of article 32 of the Cybercrime Convention. The paper draws the conclusion that investigating open sources by the police will often go beyond what is allowed on the basis of the general task description of the police (art. 2 Police Act 1993); hence, an order from the Public Prosecutor for systematic observation or intelligence is required. Moreover, the tools used must meet the non-manipulability and auditing requirements of the Dutch Decree on Technical Devices in Criminal Procedure.

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
Auteurs Joyce Kerstens en Johan van Wilsem
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

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2010
Trefwoorden Online oplichting, Slachtofferschap, Slachtofferenquête, Lage zelfcontrole
Auteurs Johan van Wilsem
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.

De rol van de Nederlandse overheid in het blokkeren van kinderpornografische websites

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 4 2009
Trefwoorden filteren, internet, kinderporno, politie
Auteurs Rutger Leukfeldt, Wouter Stol, Rik Kaspersen e.a.
SamenvattingAuteursinformatie

    The distribution of child pornography on the internet is observed as a major social problem. In the Netherlands a lively political-social discussion has emerged concerning the manner in which this can be prevented. The discussion moves between two polarities. On the one hand the dangers of internet censure are emphasised and on the other hand the need for a clamp down in which every measure seems to be justified. The present government wants to combat child pornography and by doing so answer the moral indignation of society. A means that the Dutch government, and on her behalf the police, uses, is blocking websites with child-pornographic content. The possibilities of the Dutch government to filter effectively, however, are restricted. The accuracy of existing filters is low and it is easy to get around filters. In addition, opportunities are restricted by constitutional rights. A filter that stops all websites with child pornography is bound to stop legal internet traffic too. That is at odds with the constitutional rights of freedom of expression and freedom of information gathering. The realisation of a filter that respects fundamental rights and still is able to block child pornography requires a lot of police manpower. This comes at the expense of the tracking down of criminals who produce and distribute child pornography. Furthermore, it is unknown whether the use of the child-pornography filter leads to the purposes for which they are deployed, such as hindering the sale of child pornography or reducing the abuse of children. The police, therefore, is assigned to a task that requires a considerable amount of time, but the benefits of which are unclear.
