"Y-chromosome results highlight a significant genetic differentiation between the North-Western and South-Eastern part of the Mediterranean, the Italian Peninsula occupying an intermediate position therein. In particular, Sicily and Southern Italy reveal a shared paternal genetic background with the Balkan Peninsula and the time estimates of main Y-chromosome lineages signal paternal genetic traces of Neolithic and post-Neolithic migration events."

I've had repeated experiences in academia where someone pumps me for free information or just outright lifts my work without permission/credit/citation. e.g. https://docs.google.com/document/d/1N1HCiHed7A6G2_e3-jPVKzYSPAiURVYM-unOfyI8UdQ/edit?usp=sharing

How do you remain open so that you can be reachable for truly collaborative work that respects you & remunerates you, yet closed when it comes to being viewed as someone whose work can be exploited? How do you approach this? @academicchatter

Amazing opportunity to hear Prof Martin Hammersley speak - especially for graduate students.

'Beyond the Great Divide: can qualitative and quantitative research be integrated?'

Friday, 1 December 13:00 - 14:30 online.

Prof Hammersley quite literally wrote the book(s) through which much of social science research methods are taught, and particularly in education.

I'm copying a public post below from an interesting Assistant Professor of Philosophy and Data Science at UNCC (not a medical doctor or psychologist).

Everything he is discussing is TENTATIVE but very interesting. I'm sending this out now because there is so little in the popular press about what can actually be done to help people with brain fog and other Long COVID symptoms. The research is still very early, and of course medical professionals should be consulted.

  1. The article link from Nature Magazine describes brain damage caused by SARS-CoV-2 related to cell death and especially to synapse loss, leading to cognitive impairment.

  2. The study in Bioelectric Medicine is extremely small, yet shows the potential of nicotine patches in the treatment of Long COVID symptoms including brain fog. (Another paper from the same publication also goes into why nicotine might help with Long COVID: https://bioelecmed.biomedcentral.com/articles/10.1186/s42234-023-00104-7 )

  3. He then points to a study on the NIH PubMed site reporting the encouragement of synapse growth from psilocybin.

  4. A comment in the discussion thread also links to a British Medical Journal article on Metformin improving Long COVID symptoms ( https://www.bmj.com/content/381/bmj.p1306 )

There's further speculation in the discussion thread that other psychoactive substances might be helpful. There are perhaps AI bots in the discussion thread discussing psilocybin microdosing, so be aware of that and maybe not get excited that so many "people" are discussing it.

…HUH. Long-COVID destroys synapses, and is a major contributor to the brainfog. <https://www.nature.com/articles/s41380-022-01786-2>

This goes some way to shining a light on the promising results they've been seeing in testing nicotine patches as treatment for long covid: nicotine effects synapse formation and receptivity (tests using patches because they don't habit-form and aren't, y'know, SMOKE [<https://bioelecmed.biomedcentral.com/articles/10.1186/s42234-023-00104-7>]).

But what's super interesting to me is that another thing that's also been shown to encourage synapse growth? Is psilocybin.

Two years ago, Dan Akarca & I wondered: Could the various features we observe in brains across species be caused by shared functional, structural & energetic constraints? 🧠⚡️

With our now published spatially embedded RNNs we show this is true!

"Our approach consists of a pipeline with two components: a sign detector and a wedge detector. The sign detector uses a RepPoints model with a ResNet18 backbone to locate individual cuneiform characters in the tablet segment image. The signs are then cropped based on the sign locations and fed into the wedge detector. The wedge detector is based on the idea of Point RCNN approach. It uses a Feature Pyramid Network (FPN) and RoI Align to predict the positions and classes of the wedges. The method is evaluated using different hyperparameters, and post-processing techniques such as Non-Maximum Suppression (NMS) are applied for refinement."

An evidence-based approach to accelerate flight reduction in academia

"[...] if we want to reach in all fields of , [...] we need to go beyond reducing some and strive for an adaptation of the current framework conditions. [...] we need a transformation of the academic system to keep the excellence and the necessary exchange amongst scientists but with strongly reducing the negative effects."
