Population dynamics is the type of mathematics used to model and study the size and age composition of populations as dynamical systems.Population dynamics is a branch of mathematical biology, and uses mathematical techniques such as differential equations to model behaviour.
Human Dynamics as a branch of statistical physics: Its main goal is to understand human behavior using methods originally developed in statistical physics.
The Work System Framework. The work system approach for understanding systems includes both a static view of a current (or proposed) system in operation and a dynamic view of how a system evolves over time through planned change and unplanned adaptations.
Estimates of world population by their nature are an aspect of modernity, possible only since the Age of Discovery.Early estimates for the population of the world [10] date to the 17th century: William Petty, in 1682, estimated the world population at 320 million (current estimates ranging close to twice this number); by the late 18th century, estimates ranged close to one billion (consistent ...
Labour process theory (LPT) is a Marxist theory of the organization of work under capitalism.Researchers in critical management studies, organization studies, and related disciplines have used LPT to explain antagonistic relationships between employers and employees in capitalist economies, with a particular focus on problems of deskilling, worker autonomy, and managerial control at the point ...
The term ergonomics (from the Greek ἔργον, meaning "work", and νόμος, meaning "natural law") first entered the modern lexicon when Polish scientist Wojciech Jastrzębowski used the word in his 1857 article Rys ergonomji czyli nauki o pracy, opartej na prawdach poczerpniętych z Nauki Przyrody (The Outline of Ergonomics; i.e. Science of Work, Based on the Truths Taken from the ...
The first principle of population dynamics is widely regarded as the exponential law of Malthus, as modelled by the Malthusian growth model.The early period was dominated by demographic studies such as the work of Benjamin Gompertz and Pierre François Verhulst in the early 19th century, who refined and adjusted the Malthusian demographic model.
Human overpopulation (or human population overshoot) is the idea that human populations may become too large to be sustained by their environment or resources in the long term.
