This article reports on a conceptual model that provides insight into the relationship between Twitter use by community policing officers and citizens’ safety perceptions. The model has been tested using data from a relatively large-scale survey study and these results are supporting the model. Furthermore, a small impact of Twitter use has been found on feelings of safety and judgments about the police. To confirm these findings, further research on a larger scale is necessary. To find out more about the exact positive and negative effects of Twitter use by community policing officers, a more experimental design is required.

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.
