A leader - whether bird or person - could act first due to internal traits

adaptive systems, I would have to define a CAS in such a way that it can be
interpreted in any topos --then see if we can analyze CAS's by working in a
topos.

Thanks for asking the question. In my answer, below, I describe the technical terminology impressionistically. If you want more precision, the Wikipedia articles are usually pretty good at giving precise definitions, along with some sense of the underlying ideas.
Very good
John,
I am amazed. I had no idea you were this deep down this rabbit-hole.
Has anybody out there read Sommerhoff: (sp?) Analyical Biology? About 1950.
Is it relevant?
It was concerned with what I am going to call, for want of better terms,

Ted,
Perhaps I havent been following this thread closely enough to put my oar in,
but the following passage caught my eye:
The remarkable thing about the flocking models, such as the one in JASS, is
that they show that leadership doesn't have to be due to an internal trait. It

This fits with Leigh's announcement of Melanie's talk, or at least Melanie's
seminal work in Analogy Making as Perception.
YES!!! Does anybody have links to such work!

How similar to the sperm peloton and the cyclist peloton, now we have flocks
with leaders and cliques?.
If each model has a different organizing principle then why does my simple
mind think there are similarities?
I liked Hugh Trenchard's ideas the best, there was no need for more than a

Regardless of whether leaders act because of endogenous traits or a
circumstantial opening, they are indeed emergent throughout the system.
In human systems, however, unlike flocks, over-determined structures
suppress this emergent property of the system. Rather than

Thanks, John. I'll take a look.

But by your own definition, an emergent property requires correlated
feedback in the system
supression is as likely to emerge as leadership, and thus we revert to
the question in earlier conversations about the value systems of the
observer fabricating the label of emergent or not. Right?
Some in relation to your discussion of Jass and leadership traits, but also
just on emergence itself --
I believe that Emergence principles defend individual protest as not only
being useful, but as stimuli that could help cause change when that same
individual believes no change, based on all
One additional thought on leadership, Jass, and flocking birds --
I don't think leadership can be taught to someone who does not wish to lead.

No, it's a good question, Tory. I said I wasn't sure about the label
emergent being applied to suppression, and I'm not. Thinking about it
more, it's a good idea to clarify the terminology.
Let's see ... a single act of suppression is feedback that helps to preserve
the emergent feature of a
Correlated feedback? The example given is that of a pack of dogs chasing a
rabbit and keeping it running in a straight line. The straight line is the
emergent property. A similar example is a thermostat -- or a bunch of
thermostats distributed around an area. (If you like they can control

Leigh,
Is there a more complete title for the Dynamical System Theory in Biology
volume from 1970? Is it a journal? or a series? It does sound interesting.
Thanks.
This is a book.
