Can computational methods assess the #sentiment of complex texts? In an article with my fabulous colleagues from the @WZB_Berlin, @unipotsdam @LMU_Muenchen @JungeAkademie, we answer this question by applying #dictionary and #scaling methods on a sample of #literature reviews🧵
The article is also a practical #guide to help researchers select an appropriate #method and degree of preprocessing for their own data. Our #corpus consisted of 6.041 summaries of reviews of contemporary German #literature acquired from @perlentaucher00 (2/9)
The linguistic #complexity of #literature reviews differ from other texts with regard to their #language-- ambiguity, irony, metaphors, etc.-- are comparatively difficult to capture with #computational approaches. So how did our different methods fare? (3/9)

Can one combine agent-based modelling (ABM) with qualitative comparative analysis (QCA)? For the past few days, we’ve attempted such a mixing of methods. Three teams worked on different prototypes @lorentzcenter. A thread about some of our findings. 👇 #complexity
Why combine QCA & ABM? QCA shows configurations of conditions that co-occur with an outcome (i.e., is case-based) but not the mechanisms that drive the outcome. QCA is also (mostly) static. ABM is dynamic, highlights the mechanisms but misses the configurational, case-based bit.
The two main challenges: (1) QCA runs on a set-theoretical approach to causality; ABM runs on vector causality. (2) QCA reconstructs what has happened; ABM simulates what could happen given a set of assumptions. There are technical challenges, too, of course.

Finally, the #GoldacreReview is published! (During Parliamentary Easter holidays, mid-ping-pong on the #HealthAndCareBill...)

It's 221 pages - each PDF page is a double page spread - so this could be a lo-o-o-ong [Thread].

Here goes...
First point to note, in the Terms of Reference (p5), is that this is about "access to #NHSdata by #researchers, #commissioners, and #innovators" - i.e. #Planning and #CommercialReUse - so it is directly relevant to the operation of millions of people's #NationalDataOptOuts... Terms of reference for the review  1. How do we facilitate a
"185 wide-ranging recommendations for us to explore", says @sajidjavid (p6). Gulp! Time for some coffee...

"systems that ensure #underrepresented groups are well represented" may (partly) refer to this "landmark review", which got off to a slow start:

Some people do bad things, but, they don't look bad.
They are others who do good, but, they don't look good.
It's how we are intrinsically made, that shapes our personality, defines our intentions and describes our actions.
Our #DNA is the repository that informs our evolution.
Ask the maker why he made it?
Not from the doer.
We human beings are at the receiving end, always!!
We are what we are!
We all are made according to a certain specification list.
If we try to mutate ourselves forcefully too much, we won't remain what we are.
Be #Adaptative without violating the complex laws of nature.

A select case of #Evolution and #Leftist Progression in the History of Economic Thought ->
From #Marxism to #Keynesian Economics to #MMT
#Complexity
Negative events will lead to negative outcomes :
#Bolshevik Revolution => #Intenational #Proletarianism & #Leninism
#Great #Depression -> #Keynesian Economics
#Chinese Cultural Revolution -> Gang of Four
#GFC -> Modern Monetary Theory #MMT
That is how to interpret history.
Anticipating #tippingpoint is the most essential thing a gifted leader has to his credit.
All non-linear events should be studied carefully by applying #physics in social sciences, such as #Chaos #Theory and Law of #Thermodynamics.
Yes, and #Murphy's #First Law might also help.

"Americans increased the Defence Budget to the tune of USD 200 Billion per year between 1980 and 1987"
#MacNamara.
One must learn Crisis Management from Military leaders and Geostrategic Affairs Experts.
Leadership, management and entrepreneurship can all benefit from wargaming and decision-making did on the battlefield.
An interdisciplinary approach to problem-solving helps a lot!
#MacNamara is right about three things when he sums up a crisis situation
1. Misinformation exacerbates a crisis
2. Emotionalism can ruin strategic decision-making
3. First information received in the event of a crisis is always wrong leading to an error of judgement

In the last few days, everything and its opposite has been said about the Australian submarine contract. The safety of Australians and the performance of our industrialists deserve better than peremptory statements. A #thread to better understand the Australian submarine affair.
➡️ France and submarines are serious business.⤵️
Over the past 120 years, France has built more than 250 submarines, including more than 230 conventional-powered ones. The feedback in terms of engineering and know-how is considerable.

There is a vested commercial interest in increasing #complexity around everything.
Some scholars and intellectual propagandists would like to make things appear overly complicated because that is how they can make money.
#Complexity problem can be broken down by asking relevant straightforward questions and providing equally relevant simple-minded answers which address the root causes and understands the effects.
