The purpose of this paper is to describe the development and validation of the ProKid risk assessment tool, which was designed to enable Dutch police officers to identify youths with elevated risk of committing violent and/or property crimes.

The ProKid algorithms were based on the results of logistic regression analyses of police data from a sample of 31,769 adolescents in the former police regions “Amsterdam-Amstelland” and “Gelderland-Midden”. For the validation, logistic regression analyses were performed on police data of youths in the police region “Amsterdam-Amstelland” who had been in contact with the police in 2011 (n=39,977). Furthermore, receiver operating characteristic analyses were performed to assess the instrument’s accuracy.

Results indicated that higher ProKid risk categories were associated with greater odds of being registered as a suspect of either a violent or property offence. The instrument was found to have good predictive accuracy. Area under the curve values ranged from 0.83 to 0.84 for violent offences and from 0.82 to 0.83 for property offences.

The current study demonstrates that ProKid is a valid and accurate tool to be used by police officers to identify youths with elevated risk of future violent and property offending. The automated assessment procedure enables a quick screening of large numbers of both non-offenders and offenders. This study confirms the value of official police records for assessing the risk of future offending for preventive purposes.

The present study demonstrates the validity of a risk assessment tool based on Dutch police records for both non-offenders and offenders.

Real option valuation is capable of accounting for uncertainties in residential development projects but still lacks practical adoption due to limited evidence to support application of the theory in practice. The purpose of this paper is to use option valuation to value staging option embedded in residential projects and compare with results from DCF to determine which of the two methods delivers superior results.

The fuzzy payoff method (FPOM), a real options model that uses scenario planning approach to generate a range of figures, from which a single-numerical value is computed for decision-making.

The results showed that the use of a range of figures was able to represent uncertainties to a higher degree of accuracy than the static DCF. As a result, the FPOM was able to capture about 3 per cent of the value of the project that was missed by the DCF. The staging option offers an opportunity to abandon unprofitable phases of a project, thereby limiting downside losses. Thus, real option models are practically applicable to cases in property sector.

Residential property developers must consider flexibility in financial feasibility evaluation of development because of the embedded value in uncertain property projects. It is important to account for optionality in financial evaluation of property projects for value maximisation.

The FPOM has been used for the first time to evaluate a horizontal phasing of a residential development project.

Syrian refugees in the Netherlands frequently suffer from mental health problems. It is argued that mental health not only consists of the absence of psychiatric disorders but also of the presence of mental well-being. However, there is little attention to the mental well-being of refugees, and no intervention exists that focuses on fostering the mental well-being of refugees. Therefore, the new culturally sensitive positive psychology intervention “Mosaic” was developed and implemented in collaboration with the target audience and local partners. Mosaic is offered in the Arabic language, and the content is focused on (re)finding purpose in life and (re)discovering life values and subsequently acting upon these values. The purpose of this study is to assess the effect of Mosaic on the mental well-being of Syrians in the Netherlands.

The effect of Mosaic on the mental well-being of Syrians in the Netherlands is assessed by conducting a randomized controlled trial (RCT) with a waitlist control group.

Postintervention within sample t-tests showed that the intervention group (n = 66) experienced significantly more overall mental well-being, emotional well-being and purpose in life right after participating in the intervention when compared to the preintervention measurement. The effect on purpose in life persisted six months later. These improvements were not found among the control group (n = 60).

Mosaic is the first positive psychology intervention in the Netherlands that was developed for and in collaboration with Syrian refugees. To the best of the authors’ knowledge, this study is also the first study in the Netherlands and one of the first ones in Europe that assesses the effect of positive psychology for refugees specifically.

Benchmarking is increasingly considered a useful management instrument to improve performance in healthcare. The purpose of this paper is to assess if a nationwide long-term benchmarking collaborative between operating room (OR) departments of university medical centres in the Netherlands leads to benefits in OR management and to evaluate if the initiative meets the requirements of the 4P-model.

The evaluation was based on the 4P-model (purposes, performance indicators, participating organisations, performance management system), developed in former studies. A mixed-methods design was applied, consisting of document study, observations, interviews as well as analysing OR performance data using SPSS statistics.

Collaborative benchmarking has benefits different from mainly performance improvement and identification of performance gaps. It is interesting that, since 2004, the OR benchmarking initiative still endures after already existing for ten years. A key benefit was pointed out by all respondents as “the purpose of networking”, on top of the purposes recognised in the 4P-model. The networking events were found to make it easier for participants to contact and also visit one another. Apparently, such informal contacts were helpful in spreading knowledge, sharing policy documents and initiating improvement. This benchmark largely met all key conditions of the 4P-model.

The current study has the limitations accompanied with any qualitative research and particularly related to interviewing. Qualitative research findings must be viewed within the context of the conducted case study. The experiences in this university hospital context in the Netherlands might not be transferable to other (general) hospital settings or other countries. The number of conducted interviews is restricted; nevertheless, all other data sources are extensive.

A collaborative approach in benchmarking can be effective because participants use its knowledge-sharing infrastructure which enables operational, tactical and strategic learning. Organisational learning is to the advantage of overall OR management. Benchmarking seems a useful instrument in enabling hospitals to learn from each other, to initiate performance improvements and catalyse knowledge-sharing.
