Die Allgemeine Systemtheorie bei Ludwig von Bertalanffy [PDF]

open access: yes, 2015
Die Wissenschaftsauffassung von Bertalanffy erwächst aus der Kontroverse zwischen mechanistischen und vitalistischen Positionen in der Biologie. Der reduktionistischen Position steht ein metaphysischer Ganzheitsansatz gegenüber.

Optimal and near-optimal exponent-pairs for the Bertalanffy-Pütter growth model [PDF]

open access: yesPeerJ, 2018
The Bertalanffy–Pütter growth model describes mass m at age t by means of the differential equation dm/dt = p * ma − q * mb. The special case using the von Bertalanffy exponent-pair a = 2/3 and b = 1 is most common (it corresponds to the von Bertalanffy ...
