Overzicht van Publicaties

Onze website staat vol met voorbeelden van het onderzoek dat we voor verschillende opdrachtgevers uitvoeren. De resultaten publiceren we veelal in rapporten, memo's of presentaties. Vaak zijn deze publicaties alleen bestemd voor de opdrachtgever en daarom niet openbaar. Sommige onderzoeken publiceren we echter ook in openbare literatuur en wetenschappelijke tijdschriften. Hieronder geven we een overzicht van de openbare publicaties die we de afgelopen jaren hebben uitgebracht al dan niet in samenwerking met andere internationale onderzoeksinstellingen en universiteiten.
