In der Logik von #dasSystem geschieht nichts zufällig. So können #Pandemie, #Ukrainekrieg o. #Krise problemlos auf 1 Ursprung zurückgeführt werden. Dieses vage #Unbehagen gg alles verzerrt die Wahrnehmung der Realitäten, die dann oft als absichtsvolle #Inszenierungen gelten

"Before articulating prescriptions, we first need a comprehensive diagnosis of the patient. In 2019, we are beyond a #piecemeal listing of what’s wrong. A coherent description of the global economy requires a #systems view"

#systemism
"Ecological economics acknowledges that real economies are completely dependent on energy. However, orthodox economic theory remains blind to this reality. As a result, so do our institutions and our citizenry. The disconnect has massive implications for our future."

"policymakers&many transition-scholars have too high hopes that ‘green’ innovation will be sufficient to bring about low-carbon transitions.Future agendas in research&policy should therefore pay much more attention to the #destabilization&#decline of existing fossil fuel regimes"
"The specific contribution ... is to conceptualize regime stability as the outcome of active resistance by incumbent actors. Furthermore, the paper will discuss various ways in which these actors use power and politics to resist fundamental transitions to new low-carbon #systems"

Here's a post refactoring causal layered analysis with systems lens. By linking the four layers through a #systems lens, we have a better idea of the systems intervention that we might need.

medium.com/open-source-fu…

#systemsthinking #futuresthinking #causallayeredanalysis
Myths and metaphors lead to worldviews through framing and planning assumptions. Deep stories are the base for which we view the world.

Could those planning assumptions be changed?
Worldviews get translated to causes, through policies and strategies. Could those strategies be tweaked?

Pollyanna Principle

Thread 👇
Ringelmann Effect

As a group size increases, individuals tend to become increasingly less productive

Consider a tug of war. As more people are involved, their average performance tends to decrease because each participant feels that their own effort is not critical
Group Attribution Error

Falsely assuming that the views and decision outcomes of a collective group reflect the view of each member in that group, even when information is available that indicates that all members do not support the decision

Closely related to steretyping

5 concepts to level up:

Delayed Gratification
Base Rate Neglect
Neglect of Probability
Friendship Paradox
Woozle Effect

Thread 👇
Delayed Gratification

The process an individual undergoes when resisting the temptation of an immediate reward in preference for a later reward

We live in a world of instant gratification: those who master the power of delayed gratification are the ones who win long term
Base Rate Neglect

A tendency to ignore the a priori probability of something by putting heavier weight on appealing information about an individual’s case

Only 3% of applicants make it into this school, but my daughter is brilliant. I’m sure they’re going to accept her!

Persian Messenger Syndrome

The act of blaming the bearer of negative news

Ancient Persians actually killed some messengers whose sole fault was that they brought home truthful bad news, say, of a battle lost

#HistoryofEVT

It’s no secret that #EVT for AIS has been a complete game changer for the field resulting in dramatic reduction in death & disability

Join us to explore the #history of EVT in collaboration with @SVINJournal, to celebrate the inaugural issue Image
Many thanks to @Mahmoudneuro, #RaulNogueira and @DiogoHaussen whose review entitled:
👉“Tx Advancements in the Endovascular Management of Stroke” celebrates the advances in #ETV

1st #Fun fact: Interventional treatment of AIS dates all the way back to 1950s‼️
Sussman & Fitch reported 3 cases of IA infusion of fibrinolytics
Didn’t work 😫. Probably because they were performed in a non-hyperacute fashion
But this laid the foundation for years of refinement Image

Para celebrar el 30 aniversario de Linux, os voy a contar 30 cosas que tal vez no sabíais #linux #opensource #softwarelibre #systems #sistemas
Linux fue el primer sistema operativo en incorporar controladores USB 3.0. Sage Sharp anunció el 7 de junio de 2009 que su controlador para dispositivos USB 3.0 estaba disponible y su código se incluyó en la versión 2.6.31 del núcleo.
El kernel se marca a sí mismo como "tainted" (manchado) cuando ocurre algún evento que podría ser útil para la resolución de problemas. No supone problema ejecutar un kernel "manchado". Si algo va mal, uno de los primeros pasos para solucionar el problema es intentar (1/2)

¡OpenSSL 3.0 ha sido publicado!

Tras 3 años de trabajo de desarrollo, 17 versiones alfa, 2 versiones beta, más de 7.500 commits y contribuciones de más de 350 autores diferentes, ¡por fin ha sido publicado OpenSSL 3.0!

Abro hilo...
OpenSSL 3.0 pasa a la licencia Apache 2.0. Las antiguas licencias "duales" de OpenSSL y SSLeay siguen aplicándose a las versiones más antiguas (1.1.1 y anteriores)
Esta versión mayor no es totalmente compatible con la anterior. La mayoría de las aplicaciones que funcionaban con OpenSSL 1.1.1 seguirán funcionando sin cambios y simplemente tendrán que ser recompiladas (es posible que aparezcan avisos sobre el uso de APIs obsoletas).

Warum in #Deutschland ein überfordert und fehlinformiert wirkender Armin #Laschet - dem zudem immer wieder seine #Lügen aufgezeigt werden - zum #Bundeskanzler werden kann?
Mit nur noch 17% Zutrauen durch die Wahlberechtigten?
Ein Thread (mit Hilfe von @GeorgeMonbiot) Image
Kurz nach der Wahl in #Grossbritannien 2020, die Labour verloren hat und die den "Politclown" Boris #Johnson an die Macht spülte, analysierte der Journalist @GeorgeMonbiot in knappen 10min. Video die Gründe. Brilliant und wichtig, vor allem für die #Btw21
Weil er schmerzhaft die Ursachen auf den #Punkt bringt, versuche ich im #Thread, seine Aussagen über Grossbritannien sinngemäss für #Deutschland zu übersetzen und die Beispiele zu adaptieren. Hat mich erstaunt, wie einfach das oft ist.

The #game of “economic moats” within most public #blockchains has made it hard for people to join in by forcing people to choose between geek and geeker. Go ahead and ask anyone new to #crypto how to get started and its like deer in headlights!

Time for a thread:
2/ Blockchain is a #technology that is meant to bring safety and freedom to you, yet most #dapps today have it's users completely at the control of the company that created it!
3/ When we try to use #blockchain networks, you feel like you are treated like a machine, instead of a person. Making people feel controlled and manipulated through poor system designs that have not fixed the hard part, treating you like a person.

“A Tedious Explanation of #Cannabis #Oilpens” - PART TWO starts here! You can find PART ONE here:

We are continuing our look into #hybrid #oilpen #systems:
16. Jupiter Research: I can’t quite figure out where @we_are_jupiter ends and @CCELLofficial begins. These two companies are very inter-related. The company founders helped develop the #CCell heating technology. They then brought over #CCell products to the US beginning in 2016.
They also create 510 carts, and offer several pod-based systems. There’s the #Liquid #Que - their first pod system that uses a magnetic snap-in pod with ceramic heating. There’s the #Jupiter #Liquid9 with a unique 9-sided design and pod with a built in “septum”. ImageImage

This is VERY important because we already have a mistaken belief that being "a good person" or "having empathy" can erase or mitigate racial bias or disparity when study after study proves opposite. Now we're encoding bias into #algorithms and #AI that will be called #DataDriven
This is the new frontier of #systems driven #bias. Look at the demographics of who is in #technology and #BigDataAnalytics and #AI. Look at the reputation of culture of these spaces. This puts everyone at risk even if you think you "benefit" from the bias. Inaccuracy is harm.
Just look at the #COVID19 #pandemic. Who correctly predicted AND took correct actions for good outcomes?

The risk of the most vulnerable became YOUR risk

if your #sytems and #bigdata and #BigDataAnalytics fail to capture reality

your real life results will be failure.

When people who seek control
and who monetize fear

are faced with evidence their narrative of control is false

rather than embrace reality
(or develop courage)
they double down

At times of high stress you see bizarre overpolicing & bullying increase over petty non-issues.
There is a gender difference in bullying tactics.
Men: physical
Women: social (exclusion)

Later looks/sounds like
“Don’t talk to her”
“Club”
“No one likes you”

(Yes, really adults resort to grade school tactics)

Faculty/teachers need to stay aware:

apa.org/topics/bullyin…
Whereas adults are taught “just shake it off” or “ignore it”, students or children are especially vulnerable to faculty or teacher over-policing.

This over-policing starts not just in preschool but in the cradle.

“The police” in schools: teachers.

Doctors, especially female doctors, are rushing to defend Dr. Birx

“male-centered” world is problem = latest knee jerk “feminist” defense

Men cause female doctors to not speak on scientific facts in public?
Huh?

Why isn’t female doctors saving lives of WOC part of “feminism”?
The same doctors who will jump on the “racism!” bandwagon vs @JAMA_current if vs a *man*

will rush to cover up for a woman/peer who *operationalizes* structural racism

The face of structural & medical racism is female

And women will defend women rather than be held accountable
@DrJRMarcelin published this in @JAMA_current. Women of color, specifically black women, need to be leading the conversation on #COVID19 in America because when #publichealth systems fail on top of medical racism, you get exactly the results we got.

« Comment savoir à tous les coups qu’une idée ne marchera PAS » - Episode 2

Exemple de « Lack of Control » appliqué à la vaccination en Belgique (ok, ca marche MAL plutôt que PAS).

#Requirements #Agile #Systems
L’épisode précédent a introduit la notion de « Lack of Monitoring »

Un système centralisé qui n’est pas omniscient a tendance à exposer plein de “bugs” parce qu’il prend ses décisions sur une information obsolète et/ou incomplète, qui reflète donc mal le monde réel.
Dans cet épisode, on explique le miroir « Lack of Control ».

Un système qui ne sait pas contrôler directement certaines choses, va chercher à en contrôler d’autres et “espérer” une cascade positive. Sauf qu’en pratique ça ne marche souvent pas.

C’est par là 👇

« Comment savoir à tous les coups qu’une idée ne marchera PAS »

Exemple de « Lack of Monitorability » appliqué à la vaccination en Belgique (ok, ca marche MAL plutôt que PAS).

Ou encore: pourquoi décentraliser, c’est souvent mieux?

#Requirements #Agile #Systems
Dans le thread précédent, j’indiquais l’importance d’étudier ce qui va foirer, plutôt que de foncer sur LA bonne solution.

C’est l’objectif général de l’analyse de risque, ou d’obstacles. Méthodes fort codifiées, qui peuvent être aussi “légères”.
Attention: il est facile de découvrir *après coup* les raisons pour lesquelles un système foire. Y a un côté “charognard” au requirements engineering (RE) académique, qui reste utile pour enseigner.

Cela dit, le RE invite à réfléchir *avant*, pour éviter les ennuis *après*
