Map showing tens of thousands of protests across the US between Trump's inauguration last year and January 31, 2026.
The volume & geographic distribution of protest nationwide during year 1 of Trump's second term was extraordinary.

Completely agree.
The fates of Ukraine and Europe are linked.
European security system will be destroyed without Ukraine.
Ny rapport om högskolornas budget: Det statliga "produktivitetsavdraget" innebär effektiviseringskrav på 1-2 % av budgeten/år. Idag har högskolorna 40 % mindre resurser per elev än för 30 år sedan, vilket minskat den lärarledda undervisningen drastiskt. tankesmedjanbalans.se/ny-rapport-o...

Israeli military's own data shows 83% of deaths in Gaza were civilians.
UCDP's Therese Pettersson calls the ratio "unusually high", comparable to Rwanda 1994 and Mariupol 2022.
This article highlights immense civilian suffering and raises questions about the reliability of wartime casualty data.

What drives differences between the conflict events datasets UCDP and ACLED? Contrary to previous claims, @magnusoberg.bsky.social and Mert Can Yilmaz find most differences are due to auxiliary coding rules and standards for source evaluation, not sourcing strategies or inclusion thresholds.
… we show that most of the differences are due to auxiliary coding rules, standards for source evaluation and misrepresentations of UCDP data in the Raleigh et al article (4/4)
… and how strategies for dealing with uncertainty and ambiguity impact the data. Contrary to Raleigh et al claims, the differences between ACLED and UCDP are not primarily due to differences in sourcing or inclusion thresholds. Analyzing the same cases … (3/4)
In the article, we investigate their claims about what drives differences between UCDP and ACLED. In the process we address some general issues arising in event data collection, including the importance of stable definitions, how demands on sourcing varies with the type of data collected, … (2/4)
