Generally not a fan of Nicholas Kristof but he's a sound person to track the deaths that Elon claims haven't occurred on his watch.

Achol Deng, an 8-year-old girl, was also infected with H.I.V. at birth and likewise remained alive because of American assistance. Then in January, Achol lost her ID card, and there was no longer a case worker to help get her a new card and medicines; she too became sick and died, said Labani.

Yes, this may eventually save money for United States taxpayers. How much? The cost of first-line H.I.V. medications to keep a person alive is less than 12 cents a day.

I asked Labani if he had ever heard of Musk. He had not, so I explained that Musk is the world’s wealthiest man and has said that no one is dying because of U.S.A.I.D. cuts.

“That is wrong,” Labani said, sounding surprised that anyone could be so oblivious. “He should come to grass roots.”

Another household kept alive by American aid was that of Jennifer Inyaa, a 35-year-old single mom, and her 5-year-old son, Evan Anzoo, both of them H.I.V.-positive. Last month, after the aid shutdown, Inyaa became sick and died, and a week later Evan died as well, according to David Iraa Simon, a community health worker who assisted them. Decisions by billionaires in Washington quickly cost the lives of a mother and her son.

Figure 1. Stephanie’s (Left) and April’s (Right) Paper Dolls From Initial Play.

This paper examines the ways that artful inquiry affords qualitative research students
newly creative and embodied opportunities to understand and engage with subjectivity
and bias—important concepts in the eld of qualitative inquiry. Moving beyond the
inadequacy of traditional teaching practices, such as student-generated written sub-
jectivity statements, we share here an artful methodological approach using paper dolls
to disrupt conventional engagements with these concepts. Inspired by Donna
Haraway’s emphasis on layer(ing)s of subjectivity and Karen Barad’s discussion of
cutting together-apart as a creative process, we draw from collaging in/as research to
offer this paper doll activity as a constructive and disruptive way to invite students to
consider themselves as complex, messy, and inevitable aspects of the research process.

Sometimes, when reviewing a manuscript, it's really unclear to me what precisely the authors are trying to do -- which makes it hard to evaluate the work properly.

So, here's some advice for how to ensure that readers don't get lost.

For any central statistical analysis that you report in your manuscript, it should be absolutely clear for readers why the analysis is being conducted in the first place – that is, the analysis goal s...

I think this assumption of infinite populations is not in there. In your model you can assume variation between stimuli regardless of there is a finite or infinite population of stimuli. I might be wrong of course. Moreover, inference works different there, not relying on estimated standard errors
