The Neuman systems model is a nursing theory based on the individual's relationship to stress, the reaction to it, and reconstitution factors that are dynamic in nature. [1] The theory was developed by Betty Neuman, a community health nurse, professor and counselor. The central core of the model consists of energy resources (normal temperature ...
The Comfort Theory (CT) is a broad-scope middle range theory because it contains concepts and relationships, is adaptable to a wide range of practice settings and experiences, can be built from many sources and it can be tested and measured. [7] It also qualifies as a middle range theory because of its direct applicability to nursing practice.

The nursing model is a consolidation of both concepts and the assumption that combine them into a meaningful arrangement. A model is a way of presenting a situation in such a way that it shows the logical terms in order to showcase the structure of the original idea. The term nursing model cannot be used interchangeably with nursing theory.
A von Neumann architecture scheme. The von Neumann architecture—also known as the von Neumann model or Princeton architecture—is a computer architecture based on the First Draft of a Report on the EDVAC, [1] written by John von Neumann in 1945, describing designs discussed with John Mauchly and J. Presper Eckert at the University of Pennsylvania's Moore School of Electrical Engineering.
The set N of natural numbers is defined in this system as the smallest set containing 0 and closed under the successor function S defined by S(n) = n ∪ {n}. The structure N, 0, S is a model of the Peano axioms (Goldrei 1996). The existence of the set N is equivalent to the axiom of infinity in ZF set theory.
The primitive notions of his theory were function and argument. Using these notions, he defined class and set. [1] Paul Bernays reformulated von Neumann's theory by taking class and set as primitive notions. [2] Kurt Gödel simplified Bernays' theory for his relative consistency proof of the axiom of choice and the generalized continuum ...
An initial segment of the von Neumann universe. Ordinal multiplication is reversed from our usual convention; see Ordinal arithmetic.. The cumulative hierarchy is a collection of sets V α indexed by the class of ordinal numbers; in particular, V α is the set of all sets having ranks less than α.
