New #FishSci #AcousticTelemetry positioning paper: PMC-TOA positioning.

I used adaptive importance sampling & mixture distributions to position fish in environments prone to tag reflections. Mixed with post-processing, this gives great tracks!

“I propose academic journals submit to independent regulation through an international quality-management standard. Organisations must demonstrate operations are customer-focused, committed to continual improvement, underpinned by systematic management approaches & evidence-based decision-making”
Put pressure on publishers to follow best practice — external regulation is the answer
Journals that work hard to meet the needs of both authors and readers should be acknowledged publicly — encouraging others to follow suit.

Dear #rstats,

Is there a good review paper (or vignette) that details when/how to use the tuning parameters for `optim(control = list())`.

The inner workings of these optimization algorithms are currently a blind spot for me, and i just use the default params and pray everything is fine.

"...we occasionally have to mention specific concepts before properly introducing and/or defining them---we ask the reader to bear with us in these cases."

It's always a pleasure to read papers where the author explicitly empathizes with the reader.

Just decline the peer review invitation.

What are you people even doing?
More than half of researchers now use AI for peer review — often against guidance
A survey of 1,600 academics found that more than 50% have used artificial-intelligence tools while peer reviewing manuscripts.

This sounds very cool! First time i've heard of random encounter modeling (estimating abundances from "encounters" rather than observations of individuals).

Looking forward to making some time to go through this paper in more detail.
My newest paper and 1st chapter from the PhD is also officially out!

I test how random encounter models work on reef fish 🐠Also great for anyone with a healthy dose of scepticism about reef fish survey methods

*Contains one of the most painful tables I've ever written.

That's me 👇! I'll be giving a quick overview of my #acoustictelemetry positioning and clock synchronization toolset this thursday at the OTN study hall.
This Thursday! Come chat with @rtbecard.bsky.social about kaltoa - a package for Kalman filtered time-of-arrival positioning of acoustic tag detection data. Check the User Guide linked here, and come by Study hall this Thursday for questions with James! rtbecard.gitlab.io/kaltoa/

#Rstats developers. How do you deal with windows builds of your packages? Any good CI solutions so I can always know my package is working on windows (without booting up a VM, and manually testing it myself).

Since AI slop is again all over Scientific Reports, a thread on the economics of grey-zone publishing.

Why does slop keep getting published? What does it mean for science? How can we stop this?

This is your regular reminder to please stop chasing impact factors and shitty metrics so we can stop feeding this awful system...

An alternative is to publish in more society journals (when possible).

It's frustrating that we are getting technologies that really will transform our lives, and we should be thinking carefully about what that means, but the possibility of thoughtful discussion is being squelched by a stream of soul-crushing visions and wild hyperbole coming from Silicon Valley.

Dear #Rstats, I'm looking to write some for loops that run in parallel. It's been a while since I did this and I don't know what the current state-of-the-art is... what is the generally preferred package for this within the community? thanx

(cross platform comparability is important to me).

Bluetorial-Jim Watson

I met Jim Watson a few times but did not know him well. However, I was greatly influenced by his book “The Double Helix”. He was a complicated human being with some very, very bad features, but some good contributions.

What follows is my personal perspective.
