Multi-isotope analysis of elephant ivory artefacts from Amsterdam
Abstract: During the last couple of decades, excavations in Amsterdam, the Netherlands, have uncovered many artefacts from post-medieval contexts made of elephant ivory. Historical and archaeological sources show the import of great quantities of elephant ivory by the Dutch West India Company to the Dutch Republic in the seventeenth and eighteenth centuries. These sources, however, mention only the West African coast, and the Gold Coast in particular, as the source of this ivory and do not shed any light upon the exact locations from which the ivory originated. In order to try to better determine the geographical origins of post-medieval ivory found in Amsterdam, multi-isotope analyses were conducted on twenty-one samples from objects excavated by the Office for Monuments & Archaeology. The results are the first of their kind for West Africa and suggest that ivory was derived from elephants that inhabited different parts of coastal and interior West Africa.

Wanneer wordt waterkwaliteit een probleem?
Beleidsmakers zien een goede waterkwaliteit pas sinds een aantal decennia als een beleidsverantwoordelijkheid. Deze bijdrage laat de historische achtergrond zien van de erkenning van deze problematiek. Ze belicht de strijd die wetenschappers als Han Golterman hebben geleverd om het probleem van eutrofiering op de beleidsagenda te krijgen. Naast wet- en regelgeving die leidde tot beperking van de lozing van fosfaat op oppervlakte water, is een tweede opbrengst van deze strijd, dat water beheerders nauwer zijn gaan samenwerken met wetenschappers om innovatieve benaderingen en technologieën in waterbeheer te ontwikkelen. Die samenwerking krijgt vandaag de dag vooral vorm via een goed ingeregelde kennisfunctie. Deze wordt bijvoorbeeld ingevuld door organisaties als STOWA, KNMI, KWR en diverse universitaire vakgroepen. We pleiten tot slot voor een geregelde evaluatie van de manier waarop deze kennisfunctie is toegerust op de uitdagingen in het waterbeheer van morgen.

Contextual Entity Disambiguation in Domains with Weak Identity Criteria
This article tries to use Artificial Intelligence to identify individual inhabitants of Amsterdam in the 17th century, which is difficult because of a lot of names it is unclear whether they designate the same person.

Analyzing Potential Age Cohort Effects in Car Ownership and Residential Location in the Metropolitan Region of Amsterdam
Previous research on car ownership has described ownership using a combination of socio-economic factors, demographics, individual preferences and residential factors. However, over the years people’s attitudes towards car ownership have changed as new generations are being formed. A new generation of young adults has a different view on car ownership compared to the older generation when car ownership was still a display of status. In this research a first attempt is made to disentangle the effects of age on car ownership and residential location. A discrete choice modelling approach is used where we jointly model car ownership and residential location in the metropolitan region of Amsterdam. We will start from the multinomial logit model and from there try more complex models which capture correlation among alternatives, and introduce a cohort effect for people of a certain age using a nested panel model. The main result of the model shows that car ownership in the city shows more variation in age than car ownership outside of the city.
