Bridget Conley and Alex de Waal enumerate several reasons why a perpetrator might choose to employ starvation: "(i) extermination or genocide; (ii) control through weakening a population; (iii) gaining territorial control; (iv) flushing out a population; (v) punishment; (vi) material extraction or theft; (vii) extreme exploitation; (viii) war provisioning; and (ix) comprehensive societal ...
Physiologist Ancel Keys was the lead investigator of the Minnesota Starvation Experiment. He was directly responsible for the X-ray analysis and administrative work and the general supervision of the activities in the Laboratory of Physiological Hygiene which he had founded at the University of Minnesota in 1940 after leaving positions at Harvard's Fatigue Laboratory and the Mayo Clinic.
The model-theoretic viewpoint has been useful in set theory; for example in Kurt Gödel's work on the constructible universe, which, along with the method of forcing developed by Paul Cohen can be shown to prove the (again philosophically interesting) independence of the axiom of choice and the continuum hypothesis from the other axioms of set ...
In any case, users of a model need to understand the assumptions made that are pertinent to its validity for a given use. Building a model requires abstraction. Assumptions are used in modelling in order to specify the domain of application of the model. For example, the special theory of relativity assumes an inertial frame of reference.
In control theory, the concept of positive feedback describes the same phenomenon, with the problem of balancing an inverted pendulum being the classic embodiment. The concept has also been applied to the popular acceptance of new technologies, for example being used to explain the success of VHS over Betamax. [citation needed]
Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition . In humans, prolonged starvation can cause permanent organ damage [ 1 ] and eventually, death .

Examples of toy models in physics include: the Ising model as a toy model for ferromagnetism, or lattice models more generally. It is the simplest model that allows for Euclidean quantum field theory in statistical physics.
