This week in research #139

Here's what caught my eye in research over the past week (a quiet week, it seems):

• List (open access) comments on how to address the generalisability of research
• Lehner et al. (open access) find that the opening of a Walmart Supercenter is associated with a 2.2 percentage point (18%) increase in poverty, and that the increase is largest for younger and less-educated adults

And the latest paper from my own research (led by my former PhD student Muhammad Irfan, along with Ushan Goonawardane, and Craig Robertson), which was also covered in the New Zealand Herald:

• Our new article (open access if you register for free) in the New Zealand Medical Journal performs a comparison of methamphetamine contamination of 423 properties across New Zealand, before and after the requirement to test for methamphetamine was eased in May 2018, and finds a significant increase in methamphetamine contamination
