SamenvattingAuteursinformatie

    In this study the authors examined a criminal youth gang of 35 persons in the Netherlands, using social network analysis, to answer the following questions. To what extent is it possible by means of police records to estimate the size of the complete social network of this criminal youth gang? To what extent are members of this original group part of the core of the complete network? To what extent have members of the original group a central position in the complete network (key players) and are, as such, responsible for holding the complete network together? Information is derived from police records. Results show that the size of the total network of this criminal youth gang consists of 593 individuals with a core of around hundred persons. Seven persons were identified as key players, among which six persons belonged to the original group. The social network approach in this study provides police and justice important indications for a more tailored approach regarding individuals within criminal networks.

Het episodisch geheugen en getuigenverhoor

Wat weten politieverhoorders hiervan?

Tijdschrift Tijdschrift voor Criminologie, Aflevering 3 2015
Trefwoorden interview, interviewer, police, witness, episodic memory
Auteurs Dr. Geralda Odinot, Drs. MCI Roel Boon en Laura Wolters BSc
SamenvattingAuteursinformatie

    In this study, we examined what police interviewers know about factors that affect the reliability of eyewitness testimony. We asked 143 specialist investigative interviewers from the Dutch police to complete a questionnaire about eyewitness memory. The results indicate that the police interviewers have limited knowledge of episodic memory and accompanying interviewing issues. In addition, we analyzed the interview manual from the Dutch Police Academy on coverage of the topics in our questionnaire. The poor level of knowledge of the police interviewers was correlated with lack of knowledge in the manual. Results are discussed in relation to education in police interviewing in the Netherlands.

Klokkenluiden en veiligheid

De wegen die werknemers bewandelen bij verschillende typen misstanden op het werk

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 3 2012
Trefwoorden whistle-blowing, safety, employee, report, wrongdoing
Auteurs Doris van van Dijk, Marijke Malsch, Gezinus Wolters e.a.
SamenvattingAuteursinformatie

    In the Netherlands whistle-blowing regulations are still unbalanced and ineffective in the protection of whistle-blowers and the prevention of misconduct at work. This article focuses on the question how whistle-blowing behaviour is influenced by the type and severity of the wrongdoing. The study also examines to whom employees would report (internally and/or externally), if they would report anonymously, and why they would do that or not. As far as the authors know, this is one of the first studies on whistle-blowing behaviour that systematically investigates the characteristics of the wrongdoing by using vignettes. In a two by two design, two kinds of wrongdoing (safety problem or embezzlement) at two levels of severity are plotted against each other. When confronted with severe wrongdoing, respondents intend to blow the whistle more often (externally) than with mild wrongdoing. Of the four cases, the difference between mild and severe embezzlement is most pronounced. Internally, a difference is found between the vignettes in reporting anonymously. Most respondents prefer to report to their direct supervisor, especially when a mild safety problem occurs. With severe embezzlement however, respondents prefer to report to a confidential adviser within the company. Outside the company, reporting to one’s trade union is most popular. Nearly all respondents would only report externally after an internal report has not yielded any results, or they would not report outside the company at all. They often argue that it is an internal problem and that the company could be harmed if the wrongdoing would be disclosed. This argument is used in all vignettes. Anonymity is still considered important by the majority of the respondents. It is recommended in this article that policymakers specify whistle-blowing regulations that are adaptable to the specific characteristics of the wrongdoing and the reporting employee(s).
