A roadmap on how to be as open as possible, and as closed as necessary.

On October 27th, the Young Academy Groningen, in collaboration with the Open Science Community Groningen and de Digital Competence Centers at our University organised a hackaton-style-event. The aim of the event was to produce a as-short-as-possible-as-long-as-necessary decision tree to help researchers navigate requirements from the GDPR and Open Science. Vera Heininga and Toon Kuppens were essential in all this. The outcome of that event was presented at the official launch of the Groningen Digital Competence Center.

Several interviews on the Dutch not getting taller

The CBS has published a great report on the Dutch not getting taller, or even shrinking. Naturally, I had to show up to do all sorts of interviews. Some greatest hits:





The Economist improving my graphs

Given the upcoming US elections, several media outlets have shown interest in my research on US presidential height. So did The Economist:

They definitely improved my graphs:

I should try and see if I can recreate those graphs in R.

Artikel op sociale vraagstukken

Renkse Verweij en ik hebben onlangs een artikel geschreven over ons onderzoek naar kinderloosheid voor de website van Sociale Vraagstukken: Eerst zekerheid, dan pas kinderen

Interview voor het Parool over het (jong) krijgen van kinderen

Recentelijk werd ik geïnterviewd voor het Parool over het (jong) krijgen van kinderen: De auteur van het stuk, Tom Grosfeld (25) en zijn vriendin (26) verwachten hun eerste kind. Tom beschrijft mooi hoe zijn omgeving reageert. Zijn stuk sluit nauw aan bij mijn onderzoek over sociale invloeden op de kinderkeuze!

Interview for BBC about secular trend in height

Recently, I had a hilarious and interesting interview with Professor Cregan-Reid and Kevin Mousley from the BBC about the historical changes in height and why the Dutch are so tall. You can find the interview here:

Winning hackaton “hack the educational gap"

The Groninger municipality organised an amazing hackaton “Hack the educational gap” (see here and here).

Annelene Bloemen, Denise Bouwman, Tina Kretschmer, Ymkje Anna de Vries, and I formed a team. And we won! Probably because we made neat visualisation of the existing data. See slides here.

Talk about the FLAG-research group

The Department of Sociology at Groningen celebrated its 80-year existence and a big party was thrown showcasing the diversity of research at our Department through several presentation. This was my talk presenting all members from the Families Lifecourse and Ageing Group, which I am coordinating:

New movie about research group

Creating interactive graphs: an example with twitter data

I recently had to make an interactive visualisation of some twitter-data. Here I’ll explain how I went about it. rtweet Getting twitter data is reasonably easy once you have the rtweet package going, although there are certainly some steps that you have to go through to set-up this package (with respect to the API authorization). You can read about these steps here. We’ll also use the tidyverse-package (as always, I will rely heavily on ggplot that is within the tidyverse).
