• Computation of Anticipatory Systems - weak versus strong anticipation
- incursive and hyper-incursive(Daniel Dubois; Sander Franse)
• Potential Generation of Negative Entropy in Triple-Helix Relation
(Klaus Krippendorff; Inga Ivanova)
recursive: x(t) = a x(t -1) [1 – x(t -1)]incursive: x(t) = a x(t -1) [1 – x(t)]
hyper-incursive: x(t) = a x(t +1) [1 – x(t +1)]
Example of an incursive system: Technologies develop historically with reference to their previous state;
but are selected on the market in the present
Example: The logistic curve

xt+1 = ½ ± ½ √[1 – (4/a) xt]
xt+1 = ½ ± ½ √[1 – (4/a) xt]

Mutual Information:
Tij = Hi + Hj - Hij
Tij ≥ 0; always positive
Configurational Information:
TUIG = HU + HI + HG – HUI – HIG – HUG + HUIG
TUIG is potentially negative(cf. spurious correlation)

Weaver (1949, p. 26): “Similarly one can imagine another box in the diagram which, inserted between the information source and the transmitter, would be labeled “semantic noise,” the box previously labeled as simply “noise” now being labeled “engineering noise.”

Conclusions• The scientific model (or paradigm) operates as a
system of rationalized (that is, codified) expectations;
• Codified knowledge can be considered as “a meaning that makes a difference”;
• The only system that can be reconstructed in terms of expectations (counter-factually) is the social system of communications;
• This generates redundancies; other options;• The mechanism of generating redundancy is
further codified in scientific communication.
