Hodges' Model: Welcome to the QUAD: v WCCS26: World Conference on Complex Systems 20-22nd April

Hodges' model is a conceptual framework to support reflection and critical thinking. Situated, the model can help integrate all disciplines (academic and professional). Amid news items, are posts that illustrate the scope and application of the model. A bibliography and A4 template are provided in the sidebar. Welcome to the QUAD ...

v WCCS26: World Conference on Complex Systems 20-22nd April

Day 2 Tuesday 21st April (Revisiting) Keynote Speaker: Abderrazak El Albani - 
Emergence of Intercellular Cooperation: At the Origins of Eukaryotic Complexity
Session Chair: Khawla Tadist

This keynote was fasacinating. As I begin this post on the 100th birthday of Sir David Attenborough, who would have us all see life in the broadest terms, value life and diverse habits, and Earth as our collective and shared home.

Abderrazak El Albani explained the search for LUCA the last universal common ancestor - 3.8 billion years ago. Many dates in the emergence story of humanity, have been progressively pushed back. The first fire, art, languages, our co-habitation with Neanderthal, how many first 

In healthcare, as a practitioner you have to be aware of your scope of practice. At WCCS, scale (as in iv) was ever present across research in complexity, and complex systems. Not just physical size nano-to-mega but temporal too, as we journeyed billions of miles. Several of the slides are presented here:

There is a video (French): https://www.youtube.com/watch?v=bh3t26cU7xc

I asked a question, which may have been psychological preparation for own presentation to follow. Listening, I could see how the work Abderrazak El Albani and his team are doing, could be readily translated to the search for life on Mars. There has been a 'routine' interchange of planetary material between Earth and Mars over the aeons. Fitting surely that the sedimentary rocks sought lie in  A key lesson, is that light helps us see, but not all lights are equal. Light sources brighter than the sun become incredible scientific instruments. The longevity of the dinosaurs was highlighted, at least 140 million years. There is no comparison with homo sapiens then, even as those dates have been pushed further back in time. Time defeated me as I tried to make the observation that even the dinosaurs did not make it to their first galactic birthday (c.250 million years - and what a carousel). I like the thought (slide) of 'Earth as Memory'. 

What really counted was the expressed concern about what is happening now: in the Anthropocene.

The second keynote:
Nigel Gilbert - Policy in a Complex World: Towards Complexity-Aware Policymaking
Session Chair: Ali Idri 

Was helpful to me, as the dated conundrum of benefits realisation from our technologies, and evidence-based policy still leaves a gap (for me) within the POLITICAL care/knowledge domain of Hodges' model. The illustration/graphic elements of Prof. Gilbert's slides were a brilliant complement to the content:

Prof. Nigel Gilbert - WCCS26 21st April

I wonder if within policy the constant in the equation is continuity and as a quantity it is an unknown? This seems to the case in health policy, across successive governments. You may (also) find this chart informative: https://www.cecan.ac.uk/news/the-visual-representation-of-complexity/

Perhaps, a key factor in complexity is the fact that nothing stays the same, so continuity is nuanced? Michael Quinn Patton's book Developmental Evaluation was noted re. learning while doing. Now I wish I'd held on to Qualitative Research & Evaluation Methods (4th ed.). The discussion of 'obesity system map' and 'whole systems analysis' was appreciated here.*

Since Marrakech and WCCS, I've noticed acknowledgement in the literature that 'research' is currently flooded with AI tools. I'm sure PRSM Participatory System Mapper is a welcome addition, (as noted in iv) tools to facilitate participation are much needed:

Collaborative Creativity

The Participatory System Mapper (PRSM) is an app that makes it easy to draw networks (or 'maps') of systems, working together collaboratively.'

I will definitely check this resource out; and CECAN.
