Now that this platform seems to be (blue)skyrocketing, it is probably good time to share my research topic: cracking the brain with #dMRI

Is this a tractogram of the default mode network or a Romulan warship from Star Trek?

📢 Excited to share our new paper from Synnöve Carlson’s team! We show how prematurity impacts higher-order brain network dynamics in school-aged children and adolescents:

Some publisher like Elsewier take this even further: they say that if you review 3 or more papers in a year, you will get this reward. I *bet* that most reviewers will get at th3 most 2 papers to review per year.

Viljami Sairanen @viljamisairanen.bsky.social · Jul 28

Yes. Since there is no guarantee on getting the reduction and even less guarantee that reviewer could get a paper published in the same journal (or even publisher), this is not a reward but gambling (masked as a reward).

Gambling in science vol 56: this time I refused to review a paper in MDPI journal as they practice gambling (reviewer has a random chance to obtain reduction on their APC fee).

What do you think? Is this gambling or are you just wrong?

Onko edessä ensimmäinen konferenssi? Etkö oikein tiedä, mitä siellä tapahtuu tai mitä esimerkiksi työpaja tarkoittaa? Ei hätää. Blogissani selitän konferenssiin liittyvää sanastoa.

Konferenssisanastoa - Nuoren tutkijan elämää

Miten konferenssiesitelmä eroaa posteriesitelmästä? Tai mitä tarkoittaa konferenssin työpaja? Oma mielikuvani on, että työpajassa korjataan ja rakennetaan tai upotetaan kädet saveen. Konferenssin työp...

5) I might sound pessimistic but then again the publishers make a shitload of money by providing PDFs and are well known of abusing whatever they can for profit.

I'm just waiting for the microtransactions! Review one paper and you can use *bold font* in your next paper in our prestigious journal!

Viljami Sairanen @viljamisairanen.bsky.social · May 31

4) The journal can simply reject the paper or delay the review process until the 40% discount is no longer valid (12 to 18 months).

Sure, a few will manage to get this done so the word gets out that the 'deal is true'. The rest just got scammed.

Viljami Sairanen @viljamisairanen.bsky.social · May 31

3) Skip a good night's sleep and the 4th review gets done! Yay, did you win the game?

No! The *game* has just begun. Now you need to make a paper suited to this journal.

Guess what, it is the journal's decision wether they publish or not your work. Why would they publish with reduced fee? ...

Viljami Sairanen @viljamisairanen.bsky.social · May 31

2) They don't state if 2 reviews are enough. So you are tempted to do 3rd and 4th to secure the entry ticket for the actual game*. Enter December and all the normal hurdles of end of the year. Then an editor asks you for the fourth review. You really don't have time, but you are already hooked...

Viljami Sairanen @viljamisairanen.bsky.social · May 31

1) The journal selects reviewers. There is no reason for them to offer fourth reviews equally. Some *will* get it, likewise some might win in a lottery. Majority, however, never will. This is the same old shit with a new color to exploit scientists - but even worse! ...

Viljami Sairanen @viljamisairanen.bsky.social · May 31

1/5 Loot boxes of academic publishing?

A journal asked me to review a paper. The journal "recognizes reviewers’ contributions via APC waivers". If you review 2-4 papers per year, you will get 40% off the (insanely high) pay-to-win (publish) fee.

Basically, this is the same as playing at casino...

Welcome to the dark side! I like how that gets represented even in the gui coloring on the screens (assuming left is Matlab and right is Python)

One point on the opening lecture was that the number of members hasn't increased since 2017 but costs are rising and something has to change. And at the same time stuff like this doesn't get support? Seems weird.. Highlights was a true highlight. Sad it is gone.

Does anyone with a Siemens Trio have the gradient distortion correction .coef file they'd be willing to send us?

It's hard to overstate what a big deal this paper is: onlinelibrary.wiley.com/doi/10.1002/.... Head motion in dMRI is NOT like head motion in BOLD.

Head Motion in Diffusion Magnetic Resonance Imaging: Quantification, Mitigation, and Structural Associations in Large, Cross‐Sectional Datasets Across the Lifespan

We characterized motion during diffusion MRI scans across 16,995 image sessions and find that (1) modern preprocessing pipelines effectively mitigate motion to the point where biases are not detectab....

Miten ennen tutkimuksen aloittamista voisi edes olla varma, että tulokset ei jossain kohtaa saattaisi olla ristiriidassa turvallisuuspolitiikan (=mielipide) kanssa? Katkaistaanko rahoitus kesken ja kenen päätöksellä? Jäätävää, jos tuommoinen muutos menee läpi 🥶

Tortinon rakenne koostuu lehtevästä pohjataikinasta, jonka päällä on rapeaksi paistunut marenkimainen ja makea kuorrute sekä kirpeä luumumarmeladi. Marmeladin määrällä voi säätää leivonnaisen happamuutta. Liikaa ei sovi laittaa, koska tällöin taikina ei jaksa nousta
