Diamond Open Access is a scholar-led publishing model in which content is made freely accessible to readers, under an open licence, at no cost to authors. In recent years this model has gained increased visibility and popularity as it is seen as an alternative to commercial publishing.This guide has been written for all journal editors (in the Netherlands and beyond) who find themselves uncomfortable with the hold of commercial publishers over their journals and would like to transition their journal to a Diamond Open Access publication model. It provides an overview of which steps to take while considering the flip to Diamond Open Access, which routes are possible (subscribe to open, university presses, publishing platforms and do-it-yourself publishing) and which are the costs and possibility of funding the journal under the new model.

In many graduation projects in Spatial Planning and Strategy (SP&S), empirical research and spatial design are intertwined. This chapter introduces regression analysis; a ’family’ of related models of quantitative statistical analysis in empirical research. It is very appropriate to study interactions between the built urban environment and people’s spatial behaviour in a project location at a high level of quantitative precision. The outcomes of such quantitative studies can be very useful in urban design or planning, either in preliminary empirical research, i.e. prior to design, or in the iterative cycles of Research by Design. There are several types of regression models; which one is most appropriate for your project (if any) depends on the specific questions about that interaction you want to answer, and on the empirical data that is available for that answer.
