Maia is the tale of an idea, and its improvement right into a operating speculation, that offers a cybernetic interpretation of the way development is managed. progress on the lowest point is managed through regulating the speed of progress. entry to the output of regulate mechanisms is equipped through perturbing the growing to be organism, after which filtering out the results to development expense. The output of the expansion keep an eye on mechanism is then available for interpretation and modeling. Perturbation experiments were used to supply interpretations of hormesis, the neutralization of inhibitory load and purchased tolerance to poisonous inhibition, and catch-up progress. The account starts off with an creation to cybernetics protecting the law of progress and inhabitants raise in animals and guy and describes this new method of entry the keep watch over of progress strategies. This ebook is appropriate for postgraduate scholars of organic cybernetics and researchers of organic progress, endocrinology, inhabitants ecology and toxicology.

Example text

Growth phenomena explained by Maia aspects of growth are controlled by feedback mechanisms that regulate specific growth rates, cell density, the size of organs in relation to functional load and overall size. The hierarchy of control mechanisms that exists, even in the simplest organisms, became more complex during evolution with the addition of new levels of organisation. From the perspective of growth control, each level capable of replication has its own growth control mechanism(s), creating a hierarchy of coupled control mechanisms in which none acts autonomously, as this would risk the order and stability of the organism.

A carrying capacity for the human population determined by ecological footprint analysis has already been exceeded, and there seems little hope of the population levelling out until 2100, by which time another 2 billion inhabitants will have been added to the present population. Overpopulation not only aggravates other man-made global problems, but we return to the problem with which we started (Chapters 2 and 3). Exponential growth is a positive feedback process resulting in the exponential growth rate of the global population, currently increasing at 77 million each year.

The important feature of r is that it is a measure of growth rate that is a constant, a measure that is intrinsic to the species, and independent of the number of individuals in the population. This leads to the term rN, which describes the growth rate of a population, showing that while r may be a constant, it is the increase in population size (N) that is the multiplier and is responsible for accelerating population growth. When r is multiplied by the actual size of the population (N), it gives the growth of the population.
