# ecol: mycological jazz

<< "Mycological" draws conceptually from fungal networks in forests and their interactions. Inspired by the work of ecologist Suzanne Simard, author Michael Pollan, and mycologist Paul Stamets; Krolak saw many parallels between biological networks and the social network known as jazz, as well as, the acoustic networks created when musicians interact through their instruments. Aesthetically, the work is of the free and avant-garde traditions of jazz. Drawing inspiration from John Coltrane to Sonny Sharrock to Makaya McCraven, Krolak seeks to create a space for various elements to play out and find their own connections. >>

# acad: oops! published papers in top psychology, economics, and science journals that fail to replicate are cited more than those that replicate.

<< Papers in leading psychology, economic and science journals that fail to replicate and therefore are less likely to be true are often the most cited papers in academic research, >>

The study << explores the ongoing "replication crisis" in which researchers have discovered that many findings in the fields of social sciences and medicine don't hold up when other researchers try to repeat the experiments. The paper reveals that findings from studies that cannot be verified when the experiments are repeated have a bigger influence over time. The unreliable research tends to be cited as if the results were true long after the publication failed to replicate. >>

<< We also know that experts can predict well which papers will be replicated, (..) Given this prediction, we ask 'why are non-replicable papers accepted for publication in the first place?' >> Marta Serra-Garcia.

<< Their possible answer is that review teams of academic journals face a trade-off. When the results are more "interesting," they apply lower standards regarding their reproducibility. >>

<< Interesting or appealing findings are also covered more by media or shared on platforms like Twitter, generating a lot of attention, but that does not make them true, >> Uri Gneezy.️

A new replication crisis: Research that is less likely to be true is cited more. 
University of California - San Diego. May 21, 2021. 


<< Only 12% of postreplication citations of nonreplicable findings acknowledge the replication failure. >>

# acad: apropos of pulsating, nomadic entities; to generate and manage 'theories and vagrant thoughts', by Isaac

<< Presumably, the process of creativity, whatever it is, is essentially the same in all its branches and varieties, so that the evolution of a new art form, a new gadget, a new scientific principle, all involve common factors.

# acad: oops! the scientific world is abuzz ... scientists first and foremost should "embrace uncertainty" and "be thoughtful, open and modest." ...

<< The scientific world is abuzz following recommendations by two of the most prestigious scholarly journals – The American Statistician and Nature – that the term "statistical significance" be retired. In their introduction to the special issue of The American Statistician on the topic, the journal’s editors urge "moving to a world beyond 'p<0.05,'" the famous 5 percent threshold for determining whether a study’s result is statistically significant.  (..) scientists first and foremost should "embrace uncertainty" and "be thoughtful, open and modest." >>

<< Transparent reporting is essential for the critical evaluation of studies. However, the reporting of statistical methods for studies in the biomedical sciences is often limited. >>

<< Nonparametric tests, such as the Mann-Whitney U test, Wilcoxon sign rank test and Kruskal Wallis test, may sometimes be preferable as sample sizes in basic biomedical science research are often too small to determine the data distribution. However, these tests are not commonly used. A systematic review of physiology studies showed that 3.8% used only non-parametric tests to compare continuous data, 13.6% used a combination of parametric and non-parametric tests, and 78.1% of studies used only parametric tests >>

This month fast.ai, an education non-profit based in San Francisco, kicked off the third year of its course in deep learning. (..) The course and others like it come with a simple proposition: there is no need to spend years obtaining a PhD in order to practise deep learning. (..) Fast.ai’s course can be completed in just seven weeks. >>

<< Some of the most important rules we need to discover are about how to use technology and, just as importantly, how not to use it. >>

<< The great institutional economist Clarence Ayres wrote about how technology becomes incorporated into our lives in a way that is roughly equivalent to the way tribal societies use totems to interact with each other. >>

<< Every inventor is both a Prometheus stealing fire from the gods, and a Pandora unwittingly releasing a swarm of potential evils on the world. The competition of ideas between hype and doomsaying allows us to discover helpful rules which deal with both. >>

<< Technology doesn't come with a ready-made rulebook for how to use it. We have to discover this in a process of trial, error and argument. And for this the doomsayer is just as vital as the visionary. >>
