Tuk Tuk Uber

While I was in Dar es Salaam a few weeks ago, Manuel Santana drew my attention to these three-wheeler tuk tuks with "Uber" written at the back (photo below). At first, I thought that was just a marketing strategy or perhaps a funny joke. Little did I knew that those tuk tuks are regular service providers registered with Uber. This is quite telling of Uber's flexibility to adapt to the particularities of each local context (for better or worse).

ps. In case you're wondering, we didn't take Tuk Tuk Uber... We wouldn't be able to squeeze four people in a Tuk Tuk after dinner.

Chart of the day: The rich cultural diversity of 200 Years of US immigration

The accumulated history of US immigration visualized as rings in a growing tree trunk. The chart was created by Pedro M. Cruz and John Wihbey using IPUMS data. It's the first time I see migration data depicted in this way and it does a really terrific job drawing attention to composition diversity and population history.

UPDATE: Leah Boustan has just drawn my attention on Twitter for an important shortcoming of this cart. Leah has rightly pointed that:
"This graphic is great for visualizing changes in composition of immigrant flow to US over time but obscures dramatic fluctuations in magnitude. ~1 mil immigrants entered per year in 1910, down to 100k by 1930 — yet the concentric circles makes it seem like entry grows over time"

TSU/Oxford is recruiting a Research Associate in Urban Mobility

The Transport Studies Unit (TSU / Oxford University) is recruiting a Research Associate in Urban Mobility to work on the PEAK Urban project. If you are interested on questions of transport accessibility, knowledge co-production*, transportation equity and everyday mobilities, you should take a closer look at the Job Details.

* participatory research in which local community members are involved as co-researchers.





This is a really exciting project working with Tim Schwanen (Twitter) in an extremely supportive environment with great colleagues in an excellent research center. I would jump at this opportunity if I could.
